发明名称 Wireless audio signal and control signal device and method thereof
摘要 A signal transmission arrangement includes a signal transmitter and a signal receiver wirelessly communicating with the signal transmitter. The signal transmitter includes a hybrid signal device to hybridize the audio signal with the control signal to form a consolidating signal, a frequency modulator to high-frequency modulate the consolidating signal, wherein the consolidating signal is amplified and sent to the signal receiver in a wireless manner. The signal receiver includes a frequency demodulator to demodulate the consolidating signal and a signal dissociating unit to dissociate the consolidating signal to restore the audio signal and the control signal. Therefore, the signal transmission arrangement provides a low-bit rate coding transmission in control signals, in lieu of the high-bit rate coding transmission which requires the expensive high performance integrated circuit, so as to ensure the quality of the audio signal while being cost effective.
