| Abstract: | Infrared emission control and infrared receiver tube constituting the channel to transmit audio signals, phase-locked loop technology, through frequency modulation to achieve modulated audio signal demodulation, designed a headset and loud speaker can choose to use wireless voice transmission system. System uses voice circuits for communication and information forwarded, analog phase-locked loop technology, within meters of the speech in real-time lossless transmission, the system supports the function of the audio signal for wireless communication with low power consumption, low cost, low electromagnetic interference, high security and other advantages. |
