DETAILED DESCRIPTION

Aspects of the present disclosure are directed to systems and methods suitable for use with a mobile and/or handheld device capable of participating in video and/or teleconferencing. Many individuals use a smart phone, tablet, or similar device to participate in video teleconferences, generally using a software application available for the device from a service provider.

The mobile device used in these instances typically includes hardware and software for capturing and displaying video, e.g., having a camera and a display screen, capturing and rendering audio, e.g., having at least one microphone and at least one speaker, and for controlling the user's interaction with the videoconference and/or application software, e.g., having a touchscreen or other user input means, to allow the user to operate such functions as joining and leaving the conference, muting the microphone or the speaker, starting and stopping video (incoming or outgoing), sharing content with other participants, etc.

FIGS. 1A-1C illustrate a front, side, and rear view, respectively, of an example device 100 intended for use with a mobile device (e.g. , a smart phone, tablet, or similar), to physically support the mobile device in a position useful for a user's participation in a video teleconference, to provide control inputs to the mobile device useful to control participation in the video teleconference, and to provide audio pick-up (microphone) to capture the user's voice and provide a microphone signal to the mobile device, and to render audio from the mobile device via a loudspeaker. While participation in a video conference may be described throughout this specification, systems and methods in accord with those described herein are not necessarily limited to video conferencing systems, and may be applicable to audio conferencing and/or other applications used on the mobile device with the benefit of the systems and methods herein, including the example system of device 100 and the methods implemented thereby.

The device 100 includes a main body 110 (or housing, or enclosure) enclosing a loudspeaker 120, which may be covered by a grille that allows acoustic energy, e.g., audio signals, from the loudspeaker 120 to he emitted out of at least a portion of the main body 110. The device 100 also includes a microphone 130. The device 100 is an audio device, capable of providing audio input and output, via the microphone 130 and the loudspeaker 120, respectively, to and from a mobile device. The device 100 includes various components to allow communications with a mobile device and may be coupled to the mobile device by one or more wired and/or wireless interfaces, such as by a Bluetooth© or equivalent wireless protocol. Additionally, the device 100 includes a controller (not explicitly shown) that manages the various audio input, audio output, and control inputs and outputs to and from the mobile device, including managing the communication interface with the mobile device.

According to various examples, the device 100 includes an elevated support structure for the mobile device, such as having a cradle 140 for supporting a mobile device. The cradle 140 includes at least one footing 150 and a support surface 160. In some examples, the support structure and/or the cradle 140 may have an adjustable height. According to certain examples, a top of the cradle 140 may be about 360 millimeters (mm) higher than a bottom or base of the audio device 100. In some examples, the top of the cradle 140 may be between about 240 mm and 360 mm higher than the bottom or base of the audio device 100.

In the illustrated example, the microphone 130 is located on a front facing portion of a footing 150. Accordingly, the microphone 130 is beneficially located away from the loudspeaker 120 (to reduce feedback or echo) and at a beneficial height and orientation to pick up the voice of a user when using the device 100.

The cradle 140 is supported from the main body 110, or a base thereof, by a spine 170. In various examples, the spine 170 may include an open slot 180.

The device 100 is also, according to certain examples, a control device equipped with sensor(s) to detect user input and upon which control signals may be exchanged with the mobile device. The illustrated example device 100 includes a control puck 190, having various sensors, buttons, or the like to detect user input upon which the controller may provide appropriate control signals to the mobile device. In various examples, the control puck 190 may be removable from the main body 110. FIG. 2 illustrates a closer perspective view of a portion of the device 100. In FIG. 2, various buttons 192 and a scroll wheel 194, each associated with the control puck 190, are visible. Other examples may include different types of sensors for control inputs, and the sensors may be located elsewhere in some examples. Sensors may include physical buttons, touch-sensitive surfaces, scroll wheels, proximity sensors, or any other type of sensor suitable for detecting user actions, interactions, movements, gestures, and the like.

FIG. 3 illustrates yet another view of the control puck 190, in this case removed from the main body 110. The various buttons 192 (or other sensors) may be programmed to cause the controller to send control signals to the mobile device to perform various functions, such as may be functions or features of an application running on the mobile device. Examples include muting or unmuting the microphone 130, turning on or off outgoing video, turning on or off incoming video, adjusting volume up or down, a "panic" function (a "panic" function may, for instance, carry out numerous emergency actions, such as muting the microphone 130 and turning off the outgoing video with one press), or other functions or actions. In various examples, each of the buttons 192 (or other sensors) may have pre-defined functions, may have user-configurable functions, and/or may have application specific functions depending upon the mobile device. For example, when using video teleconferencing software on the mobile device, a certain button 192 may turn off the outgoing video, but when using a music streaming application on the mobile device, the same button 192 may skip tracks.

For the example device 100, the control puck 190 also includes a scroll wheel 194, which may provide user input for various pre-configured, user- configured, or application specific actions. For example, rotating the scroll wheel 194 clockwise may increase volume while rotating the scroll wheel 194 counter-clockwise may decrease the volume, in some instances, the scroll wheel 194 may he linked to a selection displayed on the mobile device, such as scrolling through a menu or a list of options. The scroll wheel 194 may include a button 192, such that when the scroll wheel 194 is depressed lightly by the user, a selection is made and/or a function or action is activated or taken.

FIG. 4A illustrates a closer perspective view of a different portion of the device 100, and in particular illustrates the cradle 140 and spine 170. The cradle 140 includes one or more footings 150. In the instant example device 100, the cradle 140 includes two footings 150 separated by a gap. The cradle 140 also includes a support surface 160. The spine 170 includes an open slot 180. In various examples, the device 100 accommodates providing power to a mobile device when in use. In certain examples, the device 100 may include wireless charging components behind the support surface 160. For example, the cradle 140 may include a wireless charger in compliance with any of various wireless charging standards, such as from the Wireless Power Consortium, Inc. Additionally, the open slot 180 in combination with the gap between the footings 150 accommodates wired charging of a mobile device, by providing a pathway to a bottom edge of the mobile device for wire routing.

In various examples, at least a portion of the support surface 160 may be coated with a non -slip coating, such as a rubber· like or silicone material.

With reference to FIG. 4B, in certain examples, the cradle 140 may have a rearward tilt of about 5 degrees. Thereby the cradle 140 may bold the mobile device securely without the need for a clamp or other locking mechanism. Such a rearward tilt of about 5 degrees maintains physical stability, provided an ergonomic viewing angle, as well as a flattering camera angle. In various use cases, a camera is provided in the mobile device.

With reference to FIG. 4C, in various examples, each of the one or more footings 150 has a flat surface 152, substantially perpendicular to the support surface 160 of the cradle 140, upon wh ich an edge of the mobile device will rest when in use. The flat surface 152 transitions to a curve 154 which ends at an angled flat face 156. The flat surface 152 allows for curved and V- shape profiled mobile devices to not fall forward. And the curve 154 and angled flat face 156 allow for thick cases to wedge into the cradle 140, again without falling forward.

At least a portion of each of the flat surface 152, curve 154, and angled flat face 156 is covered by a non-slip coating 158, such as a rubber-like or silicone material. The non-slip coating 158, in combination with the substantially perpendicular angle between the flat surface 152 and the support surface 160, accommodates squared-edge mobile devices, retaining such mobile devices in place without the mobile device slouching or sliding forward.
