WIRELESS AUDIO TRANSMITTING METHOD AND SYSTEM ADOPTING THE METHOD

摘要

PURPOSE: A wireless sound transmitting method is provided to automatically search idle frequencies and transmit sound data through the searched frequency. CONSTITUTION: A wireless transmission unit(20) modulates by synthesizing low frequency sound signal and high frequency signal. A channel search unit searches the idle frequency channel in the transmission frequency band of the radio frequency. The frequency control part(30) controls the transmission frequency of the radio frequency corresponding to the searched idle channel. The radio frequency comprises the voltage controlled oscillator. The frequency control part generates the voltage corresponding to the transmission frequency.
