Abstract:
1. A proximity-based audio sharing system comprising two identical units in wireless communication with each other, each unit comprising: a wireless transceiver module, the wireless transceiver module comprising a first antenna configured for communicating audio signals with the first antenna of the other unit; an audio output device connected with the wireless transceiver module and configured for playing back audio signals transmitted from the wireless transceiver module; a mute control circuit connected with the wireless transceiver module and the audio output device, and configured for selectively muting the audio output of the audio output device; a microcontroller unit connected with the wireless transceiver module and configured for controlling the wireless transceiver module and the mute control circuit; and a second antenna connected with the microcontroller unit and configured for transmitting a control signal to the second antenna of the other unit; wherein: the two units are in touch or in proximity of each other; and the control signal is originated by the microcontroller unit and configured to generate a link signal for linking up with the other unit; wherein each unit further comprises a modulator and a demodulator, the microcontroller is connected to the second antenna through the modulator and the demodulator respectively, the modulator is configured to modulate a mute control signal generated by the microcontroller into the control signal, and the demodulator is configured to demodulate the modulated control signal back to a mute control signal.
