Abstract

The invention discloses a phase locking wireless audio transmitting system. The system is characterized in mainly comprising a processing chip U, a capacitor C8 of which cathode passes a resistor R7 and then is connected with the GND pin of the processing chip U, and anode passes a resistor R4 and then is taken as an audio signal input end, a resistor R5 which is connected with the capacitor C8 in parallel, and so on. According to the system, an audio signal can be processed, the amplitude of the audio signal is effectively improved, the weakness of the audio signal generated in a remote transmission process can be compensated, and the hearing effect of a receiving end can be improved. Moreover, according to the system, the phase of the audio signal is enabled to be more stable, thereby facilitating remote transmission of the audio signal.

Description

technical field [0001] The invention relates to the field of wireless transmission, in particular to a phase-locked wireless audio transmission system. Background technique [0002] The wireless audio signal transmission system consists of a wireless transmitting system and a wireless receiving system, and is used for long-distance wireless transmission of audio signals. It has been widely used in people's lives and has brought great convenience to people's lives. With the rapid development of modern technology, people have higher and higher requirements for the quality of audio signal transmission, and the audio signal will weaken during the transmission process. Therefore, the audio signal is usually processed at the transmitter, by making up for the signal The attenuation that occurs during transmission improves the hearing effect at the receiving end. However, the existing wireless audio transmission system does not have a good effect on audio signal processing, resulti...
