DESCRIPTION
The proposed device relates generally to sound
reproduction hardware, to sound-amplifying and reproducing devices in particular.
PRIOR ART
Sound reproduction systems are used to amplify acoustic playback. To enhance ease of use, improve consumer qualities, reproducing hardware, besides acoustic electromagnetic units (speakers), nowadays is mainly made active, i.e. containing at least an amplifier and sometimes a power supply unit, .
There are active sound reproducing systems equipped except for
® the amplifier, with a device for radio input (e.g., BLUETOOTH ,
®
iFi } .
E.g., the US Patent 7406294. The unit allows to transmit audio signal via radio channel to the end device.
The US Patent 7925307 describes assembly common for the patent family for sound reproduction devices that enhance receiving and transmitting signals to end units via radio channel .
Disadvantages of such units are complexity and lack of mobility.
The US Patent 7653344 describes most similar assembly of a sound playback device, allowing to receive signals from a large number of devices (not simultaneously) and transfer them to end devices over radio channel.
Disadvantages of units are complexity and lack of
mobility.
This devise was chosen as prior art.
Technical result attained by the proposed device is enhancing convenience, mainly by simplifying the design by denying all controls on the outer surfaces thereof, mobility, due to absence of wires, possibility to install the device in any room without additional special means, fasteners, tools and labor, external power supply, expanding the range of devices of this type, increasing consumer qualities.
Known devices do not allow to fully or in part reach these results .
DESCRIPTION OF INVENTION
BRIEF SUMMARY
A sound reproducing system is proposed hereinafter
comprising central-control unit and one or more peripheral speaking units made with the possibility of transmitting and receiving an input multi-channel signal over a wireless
(mainly radio) channel, and with a possibility of transmittal and receiving of peripheral unit diagnostic data, namely autonomous power supply charge level and any other data.
DETAILED DESCRIPTION
Proposed herein is a sound reproducing system made in form of a polyhedron, with the possibility to use each side as base with the possibility of receiving an input multi-channel signal over a wireless (mainly radio) channel, with possibility of that selection and application of the channel received or operation mode
unambiguously depending on the unit spatialization, i.e., which side is used as the base.
The unit is in a switched off mode when placed on front or back side of the unit.
The unit powered on mode can be achieved either by placing the device in a certain side as a base (by simultaneously assigning one side to be used as base for switching on) or by turning on one of radiochannels or operation modes.
Input signal is preferably received via radiochannel .
However, input signal may be transmitted by ultrasound, sound, infrared or another well-known type of wireless channel.
The number of sides of the device is selected basing on number of channels and operation modes.
Switching means may contain one or more gravity sensors that react to unit's position. Position of the unit may be detected with an optical, ultrasound, super-high-frequency sensor or any type of sensor suitable by accuracy, size, efficiency and other operational parameters .
Power supply means can operate both connected to mains and in standalone mode - it may contain an autonomous power source, such as a rechargeable battery.
Switching means is performed with ability to directly connect to one of a number of possible channels and/or activate one of several operation modes of the unit depending on what side of the unit is used as the base.
Tuning to another channel and/or changing to another operational mode occurs after the unit has changed its spatial orientation, e.g. has been turned and placed on another side as a base.
Installation on wall or another support is possible. In this case operation mode and/or channel received depends on what side of the unit is facing downwards. This implementation of the unit requires to provide suspending mechanism with the possibility to rotate the unit along one or more axes.
UNIT OPERATIO .
Initial position is that the unit is on its shut-off side - say, face side or back side.
In order to switch it on, select the mode in which the unit is to operate (for a hex body) - - "MONO", "LEFT FRONT", "CENTER FRONT", "RIGHT FRONT" , "LEFT REAR", "RIGHT REAR" and select the corresponding side as the base. At this moment power supply is switched on and the spatial-orientation- dependent switch engages necessary channel. Input channel is received from a designated channel, amplified in power amp and played back via speakers. In order to change received signal the body is to be turned and placed on corresponding side as a base. After work the unit is to be placed on its face or back side to be switched off.
