TUNING PARAMETERS TRANSMISSION

Background

[0001] Audio output devices may utilize techniques to convert an audio signal into a corresponding sound. Audio output devices can be included in computing devices. For example, an audio output device included in a computing device may be utilized to play sounds, including instructions, alerts, voice, multimedia including video and/or music, and/or other types of sounds.

[0003] Figure 2 illustrates an example of a computing device including a controller, amplifier, and audio output device for tuning parameters transmission consistent with the disclosure.

[0004] Figure 3 illustrates an example of a computing device including a controller, amplifier, and audio output device for tuning parameters transmission consistent with the disclosure.

[0005] Figure 4 illustrates a block diagram of an example system for tuning parameters transmission consistent with the disclosure.

Detailed Description

[0006] Some computing devices can include audio output devices to output sounds. As used herein, the term “audio output device” refers to a device capable of converting electrical signals to sound and/or pressure waves. For example, a computing device may include an audio output device to output instructions, alerts, voice, multimedia including video and/or music, and/or other types of sounds.

[0007] A computing device may include an amplifier. As used herein, the term “amplifier” refers to an electronic device to increase the power of a signal. For example, an amplifier can increase the amplitude of a signal for output by an audio output device.

[0008] Certain amplifiers may be tuned so that an audio output device can produce an audio output having an acceptable sound quality. For example, an amplifier can include parameters that can be tuned so that the audio output device can output audio at an acceptable sound quality.

[0009] Certain computing devices can include a controller that can transmit a tuning parameter to an amplifier. Such a tuning parameter may be generated according to a user such as an audio engineer using a separate computing device and transmitted to the controller of the computing device having the amplifier and audio output device via a controller firmware update mechanism. The controller can then transmit the tuning parameter to the amplifier. The user can then cause the audio output device to output sound to determine whether the tuning parameter causes the audio output device to output sound that is of acceptable sound quality.

[0010] However, such an approach can rely on subjective listening by the user to determine whether the output sound is of acceptable sound quality. For example, one user may find the output sound to be of acceptable sound quality, whereas another user may not be able to find the output sound to be of acceptable sound quality. Such differences may lead to inconsistent sound output between computing devices.

[0011] Additionally, such users may rely on amplifiers on a separate computing device including a testing and evaluation sound board to generate the initial tuning parameter. Accordingly, the audio output device included in the separate computing device is not housed in the same mechanical enclosure as that of the amplifier on the testing and evaluation sound board, which can result in tuning parameters which can produce unacceptable sound quality.

[0012] Further, when a user subjectively deems the output sound to be of unacceptable sound quality, the user has to generate a modified tuning parameter on the separate computing device. This modified tuning parameter has to then be re-transmitted to the controller of the computing device having the amplifier and audio output device via the controller firmware update mechanism, which can then transmit the modified tuning parameter to the amplifier. The user can then cause the audio output device to output sound to determine whether the modified tuning parameter causes the audio output device to output sound that is of acceptable sound quality, if the output sound is still of unacceptable sound quality, the user has to then perform the process again until there is a subjective determination of acceptable sound quality.

Such approaches can be time consuming and lead to inconsistent results.

[0013] Tuning parameters transmission according to the disclosure can allow for a controller to receive a tuning parameter and transmit the tuning parameter to an amplifier for use by the amplifier. Such tuning parameters can be generated and transmitted by the computing device having the amplifier and an audio output device in the same mechanical enclosure, allowing for more consistent tuning of the amplifier and audio output of the audio output device. Additionally, the controller can directly receive the tuning parameter and transmit the tuning parameter to the amplifier using an established communication channel and protocol, foregoing the use of the controller firmware update mechanism allowing for tuning parameters to be generated, modified, and/or transmitted easier and faster than previous approaches. Further, the controller can analyze audio data from the amplifier which can be utilized by the computing device to modify tuning parameters so as to avoid subjective listening tests by a user, allowing for consistent audio tuning of audio output devices as compared with previous approaches.

[0014] Figure 1 illustrates an example of a computing device 100 for tuning parameters transmission consistent with the disclosure. As illustrated in Figure 1, the computing device 100 can include a controller 102, an amplifier 104, and an audio output device 106.

[0015] As Illustrated in Figure 1, the computing device 100 can include an audio output device 106. As used herein, the term “computing device” refers to an electronic system having a processing resource, memory resource, and/or an application-specific integrated circuit (ASIC). Examples of computing devices can include, for instance, a laptop computer, a notebook computer, a desktop computer, networking device (e.g., router, switch, etc.), and/or a mobile device (e.g., a smart phone, tablet, personal digital assistant, smart glasses, a wrist-worn device, etc.), among other types of computing devices. As used herein, a mobile device can include devices that are (or can be) carried and/or worn by a user. For example, a mobile device can be a phone (e.g., a smart phone), a tablet, a personal digital assistant (PDA), smart glasses, and/or a wrist-worn device (e.g., a smart watch), among other types of mobile devices. [0018] The computing device 100 can include the audio output device

106. For example, the computing device 100 may utilize the audio output device 106 to output instructions, alerts, voice, multimedia, etc. For instance, the computing device 100 may be utilized by a user to play multimedia (e.g., video, music, etc.), and the audio output device 106 can accordingly audibly output the multimedia via sound and/or pressure waves. The audio output device 106 can be a speaker. However, examples of the disclosure are not so limited. For example, the audio output device 106 can be any electroacoustic device to audibly emit an audio output.

[0017] The audio output device 106 can be connected to an amplifier 104. The amplifier 104 can increase the amplitude of a signal for output by the audio output device 106. For example, the computing device 100 can transmit a signal to the amplifier 104, where the signal is to cause the audio output device 106 to emit an audio output. The amplifier 104 can increase the amplitude of the signal and transmit the signal to the audio output device 106, as is further described herein.

[0018] The computing device 100 can include a controller 102. The controller 102 can be connected to the amplifier 104. The controller 102 can transmit a tuning parameter to the amplifier 104, as is further described in connection with Figure 2.

[0019] As described above, the amplifier 104 can amplify an audio signal for output by the audio output device 106. The amplifier 104 can utilize a tuning parameter to amplify the audio signal and transmit the amplified audio signal to the audio output device 106. The audio signal can be amplified according to the tuning parameter in order to produce an audio output of a particular sound quality. Accordingly, the audio output device 106 can utilize the amplified audio signal to emit an audio output, as is further described in connection with Figure 2.

[0020] Figure 2 illustrates an example of a computing device 200 including a controller 202, amplifier 204, and audio output device 206 for tuning parameters transmission consistent with the disclosure. As illustrated in Figure 2, the computing device 200 can include a controller 202, an amplifier 204, and an audio output device 206.

[0021] Although not illustrated in Figure 2, the controller 202 may include a processing resource for retrieval and execution of non-transitory machine- readable instructions stored in a memory resource (not illustrated in Figure 2). For example, the processing resource may fetch, decode, and execute stored instructions to perform actions related to tuning parameters transmission, as is further described in connection with Figure 4.

[0022] The memory resource may be any electronic, magnetic, optical, or other physical storage device that stores the non-transitory machine-readable executable instructions and/or data. Thus, memory resource may be, for example, Random Access Memory (RAM), an Electricaily-Erasabie Programmable Read-Only Memory (EEPROM), a storage drive, an optical disc, and the like. The memory resource may be disposed within the computing device 200. Additionaliy, the memory resource may be a portable, external or remote storage medium, for example, that causes the computing device 200 to download the instructions from the portab!e/externai/remote storage medium. [0023] The controller 202 can, at 212, establish a communication channel 208 between the amplifier 204 and the controller 202. As used herein, the term “communication channel” refers to a transmission medium to convey an information signal. For example, the controller 202 can establish the communication channei 208 in order to transmit a signal from the controller 202 to the amplifier 204.

[0024] The controller 202 can, at 214, disable a control logic for the amplifier 204 in response to a tuning mode of the computing device 200 being enabled. As used herein, the term “control logic” refers to instructions that control operation of a hardware component. For example, the control logic that controls the amplifier 204 and/or the audio output device 206 according to an operating parameter (e.g., a tuning parameter) can be disabled in response to a tuning mode of the computing device 200 being enabled. As used herein, the term “tuning mode” refers to a mode of operation of a computing device which can allow for modification of an operating parameter of a hardware device of the computing device. For example, the tuning mode of the computing device 200 can allow for modification of an operating parameter (e.g., a tuning parameter) of a hardware device (e.g., an amplifier 204 which controls an audio output device 206) when enabled, as is further described herein.

[0025] The controller 202 can, at 216, receive a tuning parameter for the audio output device 206. As used herein, the term “tuning parameter” refers to an adjustable variable that characterizes an aspect of an audio output. For example, a tuning parameter can characterize an aspect of the emission of an audio output from the audio output device 206.

[0028] Although the controller 202 is described above as receiving a tuning parameter for the audio output device 206, examples of the disclosure are not so limited. For example, the controller 202 can receive multiple (e.g., more than one) tuning parameters for the audio output device 206.

[0027] In some examples, the tuning parameter can include an equalizer setting for the audio output device 206. As used herein, the term “equalizer setting” refers to a variable that characterizes a balance between frequency components within an electronic signal. For example, the tuning parameter can include an equalizer setting that can specify the balance of particular frequency ranges included in a signal that includes information relating to an audio output to be emitted by the audio output device 206.

[0028] In some examples, the tuning parameter can include a hardware configuration for the amplifier 204 and/or the audio output device 206. For example, the hardware configuration can include a voltage level for the amplifier 204 and/or the audio output device 206, impedance level for the amplifier 204 and/or the audio output device 206, Automatic Gain Control (AGC) for the amplifier 204, excursion protection (e.g., parameters for Thiele/Small parameters of the audio output device 206), thermal protection (e.g,, parameters for thermal characteristics of the audio output device 206), etc.

[0029] in some examples, the tuning parameter can include frequency settings for the amplifier 204 and/or the audio output device 206. For example, the frequency settings can include a resonant frequency of the audio output device 206, a frequency resolution of the audio output device 206, parametric equalization (e.g., application of different filters and/or adjustment of gains at different frequency bands), multiband dynamic range compression (MBDRC) (e.g., application of different compressions in different frequency bands), etc.

[0030] Although the tuning parameters are described above as including equalizer settings, hardware configurations, and/or frequency settings, examples of the disclosure are not so limited. For example, the tuning parameters can include any other adjustable variable that can characterize an aspect of the audio output from the audio output device 206.

[0031] The controller 202 can, at 218, transmit the tuning parameter to the amplifier 204. The controller 202 can transmit the tuning parameter via the communication channel 208. For example, the controller 202 can receive an equalizer setting and frequency resolution for the audio output device 206, and can transmit the equaiizer setting and frequency resolution to the amplifier 204 through the communication channel 208 for use by the amplifier 204.

[0032] In some examples, the controller 202 can transmit a tuning parameter to the amplifier 204 via an i-squared~C (i 2 C) bus. Continuing with the example above, the controller 202 can transmit a signal including the equalizer setting and frequency resolution to the amplifier 204 through the communication channel 208 using an i 2 C bus and communication protocol. The tuning parameter (e.g., the generated equalizer setting and frequency resolution) can be transmitted to the amplifier 204 as a packet having a particular number of bytes using the i 2 C bus and protocol.

[0033] The amplifier 204 can utilize the tuning parameter to amplify an audio signal and transmit the amplified audio signal to the audio output device 206. For example, a user may desire to listen to music, and the computing device 200 can generate and transmit an audio signal (e.g., the music) to the amplifier 204, The amplifier 204 can amplify the audio signal according to the tuning parameters and transmit the amplified audio signal to the audio output device 206. The audio output device 206 can utilize the amplified audio signal to emit an audio output For example, the music the user desires to listen to can be audibly output by the audio output device 206.

[0034] In some examples, a user may be an audio technician. While the tuning mode of the computing device 200 is enabled, the user may test the audio output from the audio output device 206 for sound quality. For example, the computing device 200 may be in testing prior to being shipped to a customer, and the audio technician may test the audio output device 206 to ensure sound quality is of an acceptable level. The audio technician may generate a tuning parameter via a processor of the computing device (e.g., as is further described in connection with Figure 3) and cause the audio output device 206 to emit an audio output utilizing the tuning parameter. The user may listen to the audio output and/or review analyzed audio data from the amplifier 204 to modify the generated tuning parameter, as is further described in connection with Figure 3.

[0035] Figure 3 illustrates an example of a computing device 300 including a controller 302, amplifier 304, and audio output device 306 for tuning parameters transmission consistent with the disclosure. As illustrated In Figure 3, the computing device 300 can include a controller 302, an amplifier 304, an audio output device 306, and a processor 311. The controller 302 can include an input/output (I/O) port 310.

[0036] Although not illustrated in Figure 3, as previously described in connection with Figure 2 the controller 302 may include a processing resource and a memory resource. The processing resource may fetch, decode, and execute instructions stored in the memory resource to perform actions related to tuning parameters transmission.

[0037] The controller 302 can establish a communication channel 308 between the amplifier 304 and the controller 302. For example, the controller 302 can establish the communication channel 308 in order to transmit a signal from the controller 302 to the amplifier 304, as is further described herein. [0038] The controller 302 can, at 320, disable a control logic for the amplifier 304. For example, a user may desire to test the amplifier 304 and/or the audio output device 308 for sound quality. The user can cause a tuning mode of the computing device 300 to be enabled, in response to the tuning mode being enabled, the controller 302 can disable the control logic for the amplifier 304 in order to transmit a tuning parameter, as is further described herein.

[0039] In some examples, the tuning mode can be enabled in response to the computing device 300 being powered on. For example, when a user turns on the computing device 300, the tuning mode may be enabled in order to transmit a tuning parameter to the amplifier 304.

[0040] As illustrated in Figure 3, the computing device 300 can include a processor 311. The processor 311 can be a processing resource for retrieval and execution of non-transitory machine-readable instructions stored in a memory resource (not illustrated in Figure 3). For example, the processor 311 may fetch, decode, and execute stored instructions to perform actions related to tuning parameters transmission.

[0041] The processor 311 can generate a tuning parameter. For example, a user may specify an equalizer setting for the amplifier 304. The processor can transmit the generated tuning parameter (e.g., the equalizer setting) to the controller 302.

[0042] The controller 302 can, at 322, receive the tuning parameter for the audio output device 308 connected to the amplifier 304. The received tuning parameter can characterize an aspect of the emission of an audio output from the audio output device 306. The tuning parameter can be received from the processor 311 via an I/O port 310, as is further described herein.

[0043] As illustrated in Figure 3, the controller 302 can include an I/O port 310. As used herein, the term I/O port” refers to a memory address used to transfer data. The I/O port 310 can be utilized to exchange information (e.g., signals) between the controller 202 and the processor 311. The signal can be, for example, a tuning parameter.

[0044] The tuning parameter can be transmitted between the processor 311 and the controller 302 and the amplifier 204 via an advanced configuration and power interface (ACPI) protocol. As used herein, the term “ACPI protocol” refers to a standard for an operating system to use to discover and manipulate computer hardware components, perform power management for computer hardware components, and/or perform status monitoring for computer hardware components.

[0045] Although the controller 302 is illustrated in Figure 3 as including one I/O port 310, examples of the disclosure are not so limited. For example, the controller 302 can include two I/O ports or more than two I/O ports, in some examples, the controller 302 can utilize the two I/O ports 310 to exchange signals between the processor 311 and the controller 302.

[0046] The controller 302 can, at 324, transmit the received tuning parameter to the amplifier 304. The tuning parameter can be transmitted to the amplifier 304 through the communication channel 308.

[0047] The audio output device 306 can emit an audio output utilizing an audio signal from the amplifier 304 that has been amplified according to the tuning parameter. For example, the tuning parameter can include the equalizer setting, and the audio output emitted by the audio output device 306 can be from an audio signal amplified by the amplifier 304 according to the equalizer setting.

[0048] The controller 302 can receive audio data from the amplifier 304. As used herein, the term “audio data” refers to information that describes an audible output in a digital format. For example, audio data can include MBDRC and/or AGC gains, diaphragm displacement for the audio output device 306, coil temperatures of the audio output device 306, and/or any other detectable and/or measurable tuning parameter associated with the amplifier 304 and/or the audio output device 306, among other types of audio data. The amplifier 304 can record audio data from the audio output device 306 and can transmit the audio data to the controller 302 via the communication channel 308.

[6049] The controller 302 can transmit the received audio data from the amplifier 304 to the processor 311. The processor 311 can analyze the audio data. For example, the processor 311 can compare the diaphragm displacement of the audio output device 306 to a predetermined range of displacement values. In response to the comparison, the processor 311 can provide an indication as to whether a tuning parameter is within the predetermined range of values or outside the predetermined range of values, (e.g., whether diaphragm displacement is outside of the predetermined range of displacement values or inside the predetermined range of displacement values). [0050] The processor can, at 325, modify the tuning parameter. For instance, a user may review the analyzed audio data received from the amplifier 304 and determine that based on the analyzed audio data, the tuning parameter should be modified. In some examples, the user may review the analyzed audio data and determine that the diaphragm displacement of the audio output device 308 is a value that is outside of a predefined range of values,, and the user may decide to modify a tuning parameter based on the diaphragm displacement of the audio output device 306 being outside of a predefined range of values. In some examples, the user may review the analyzed audio data and determine that, based on gain settings from AGC, the user may decide to modify a tuning parameter. Accordingly, the user can cause, via a user input to the computing device 300, the processor 311 to modify a tuning parameter. [0051] In some examples, the processor can modify the tuning parameter automatically based on the analyzed audio data. For example, the processor 311 can determine that a diaphragm displacement of the audio output device 306 is outside of the predetermined range of displacement values and in response, modify a tuning parameter. The tuning parameter modified by the processor 311 can be a tuning parameter that can cause the diaphragm displacement of the audio output device 306 to be within the predetermined range of displacement values.

[0052] Although the processor 311 is described above as analyzing audio data including diaphragm displacement and/or gain settings from the AGC and modifying a tuning parameter associated with the diaphragm displacement and/or modifying gain settings, respectively, examples of the disclosure are not so limited. For example, the processor 311 can analyze any audio data from the amplifier 304 and can modify any tuning parameter based on the audio data. [0053] The processor 311 can transmit the modified tuning parameter to the controller 302. For example, the modified tuning parameter associated with diaphragm displacement for the audio output device 306 can be transmitted to the controller 302.

[0054] The controller 302 can, at 326, transmit the modified tuning parameter to the amplifier 304 for use by the amplifier 304. Similar to the generated tuning parameter, the modified tuning parameter can be transmitted to the amplifier 304 through the communication channel 308.

[0055] The amplifier 304 can utilize the modified tuning parameter to amplify an audio signal and transmit the amplified audio signal to the audio output device 306. The audio output device 306 can emit an audio output utilizing the audio signal from the amplifier 304 that has been amplified according to the modified tuning parameter. For example, the audio output emitted by the audio output device 306 can be from an audio signal amplified by the amplifier 304 according to the modified equalizer setting. A user may repeat this process for other tuning parameters for the amplifier 304 and/or the audio output device 306 until the user Is satisfied with the sound quality of the audio output device 306.

[0056] The controller 302 can enable, in response to the tuning mode of the computing device 300 being disabled, the control logic for the amplifier 304. For example, an operational mode of the computing device 300 may be enabled such that the control logic for the amplifier 304 can control operation of the amplifier 304 and/or the audio output device 306. As used herein, the term “operational mode” refers to a mode of operation of a computing device which does not allow for modification of an operating parameter of a hardware device of the computing device. For example, when the operational mode of the computing device 300 is enabled, a tuning parameter is not able to be modified. Accordingly, during normal operation of the computing device 300, the control logic for the amplifier 304 is enabled, preventing generation and/or modification of a tuning parameter. In some examples, the tuning mode of the computing device 300 can be disabled and the control logic for the amplifier 304 enabled after a user has completed tuning of the audio output device 306 by generating and/or modifying tuning parameters until the audio output device 306 can emit an audio output that is of an acceptable sound quality.

[0057] The amplifier 304 can utilize the tuning parameter (e.g., generated tuning parameter and/or modified tuning parameter) while the computing device 300 is powered on. For example, as previously described above, the tuning mode of the computing device 300 can be enabled in response to the computing device 300 being powered on. When the computing device 300 is powered on, the controller 302 can disable control logic for the amplifier 304 and enable a tuning mode, transmit the tuning parameter to the amplifier 304 for use while the computing device 300 is powered on, and disable the tuning mode such that the amplifier 304 can utilize the tuning parameter while the computing device 300 is powered on.

[0058] Tuning parameters transmission according to the disclosure can allow for generation and/or modification of tuning parameters for an amplifier and an audio output device to provide more consistent tuning of the amplifier and audio output device as compared with previous approaches. Further, the controller can directly transmit the tuning parameters to the amplifier via a communication channel, allowing for tuning parameters to be generated, modified, and/or transmitted easier and faster than previous approaches.

[0059] Figure 4 illustrates a block diagram of an example system 430 for tuning parameters transmission consistent with the disclosure in the example of Figure 4, system 430 includes a processing resource 432 and a non- transitary machine-readable storage medium 434. Although the following descriptions refer to a single processing resource and a single machine- readable storage medium, the descriptions may also apply to a system with multiple processors and multiple machine-readable storage mediums. In such examples, the instructions may be distributed across multiple machine-readable storage mediums and the instructions may be distributed across multiple processors. Put another way, the instructions may be stored across multiple machine-readable storage mediums and executed across multiple processors, such as in a distributed computing environment. [0080] Processing resource 432 may be a centra! processing unit (CPU), microprocessor, and/or other hardware device suitable for retrieval and execution of instructions stored in machine-readable storage medium 434. In the particular example shown in Figure 4, processing resource 432 may receive, determine, and send instructions 436, 438, and 440. As an alternative or in addition to retrieving and executing instructions, processing resource 432 may include an electronic circuit comprising a number of electronic components for performing the operations of the instructions in machine-readabie storage medium 434. With respect to the executable instruction representations or boxes described and shown herein, it should be understood that part or all of the executable instructions and/or electronic circuits included within one box may be included in a different box shown in the figures or in a different box not shown.

[0081] Machine-readable storage medium 434 may be any electronic, magnetic, optical, or other physical storage device that stores executable instructions. Thus, machine-readable storage medium 434 may be, for example, Random Access Memory (RAM), an Electrically-Erasable Programmable Read-Only Memory (EEPROM), a storage drive, an optical disc, and the like. The executable instructions may be “installed” on the system 430 illustrated in Figure 4. Machine-readabie storage medium 434 may be a portable, external or remote storage medium, for example, that allows the system 430 to download the instructions from the portable/external/remote storage medium. In this situation, the executable instructions may be part of an “installation package”. As described herein, machine-readabie storage medium 434 may be encoded with executable instructions associated with tuning parameters generation.

[0082] Disable instructions 436, when executed by a processor such as processing resource 432, may cause system 430 to disable control logic for an amplifier of a computing device. For example, in response to a tuning mode of the computing device being enabled, the controller 402 can disable the control logic for the amplifier. [0083] Receive instructions 438, when executed by a processor such as processing resource 432, may cause system 430 to receive a tuning parameter for an audio output device connected to the amplifier. The tuning parameter can characterize an aspect of the emission of an audio output from the audio output device. The tuning parameter can be received from a processor of the computing device (e.g., not illustrated in Figure 4).

[0084] Transmit instructions 440, when executed by a processor such as processing resource 432, may cause system 430 to transmit the tuning parameter to the amplifier for use by the amplifier. The tuning parameter may be transmitted to the amplifier via a communication channel. The amplifier can utilize the tuning parameter to amplify an audio signal and transmit the amplified audio signal to the audio output device. The audio output device can emit an audio output utilizing the tuning parameter.

[0085] In the foregoing detailed description of the disclosure, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration how examples of the disclosure may be practiced. These examples are described in sufficient detail to enable those of ordinary skill in the art to practice the examples of this disclosure, and it is to be understood that other examples may be utilized and that process, electrical, and/or structural changes may be made without departing from the scope of the disclosure.

[0088] The figures herein follow a numbering convention in which the first digit corresponds to the drawing figure number and the remaining digits identify an element or component in the drawing. Similar elements or components between different figures may be identified by the use of similar digits. For example, 104 may reference element “04” in Figure 1, and a similar element may be referenced as 204 in Figure 2.

[0087] Elements illustrated in the various figures herein can be added, exchanged, and/or eliminated so as to provide a plurality of additional examples of the disclosure. In addition, the proportion and the relative scale of the elements provided in the figures are intended to illustrate the examples of the disclosure and should not be taken in a limiting sense. As used herein, "a plurality of an element and/or feature can refer to more than one of such elements and/or features.
