Abstract

The invention discloses a high-linearity wireless audio transmission system. The system is characterized by mainly comprising a processing chip U and a capacitor C8. A negative electrode of the capacitor C8 is connected with a resistor R7 and then a GND pin of the processing chip U, and a positive electrode of the capacitor C8 is connected with a resistor R4 and then used as an audio signal input end. The system can process an audio signal. The system can improve the amplitude of the audio signal, thereby compensating for the weakness of the audio signal caused during long-distance transmission and improving the hearing effect of the receiving end. The system can also make the amplitude of an output audio signal proportional to the amplitude of an input audio signal, avoid non-linear distortion of the audio signal, improve the stability of the audio signal, and thus facilitate long-distance transmission of the audio signal.

Description

technical field [0001] The invention relates to the field of wireless transmission, in particular to a high-linearity 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, resul...
