Abstract

The invention discloses a high-linearity phase lock type wireless audio transmission system, which is characterized by mainly consisting of a processing chip U, and a capacitor C8, wherein the negative electrode is connected with a GND pin of the processing chip U after passing through a resistor R7, and a positive electrode is used as an audio signal input end after passing by a resistor R4. The high-linearity phase lock type wireless audio transmission system disclosed by the invention can process audio signals to effectively improve the amplitudes of the audio signals, so that the fading of the audio signals generated in a long distance transmission process can be compensate to improve the auditory effect of a receiving end. Meanwhile, the high-linearity phase lock type wireless audio transmission system disclosed by the invention can ensure more stable phases of the audio signals and can also form a direct proportion between the amplitudes of the output audio signals and the amplitudes of the input audio signals, thereby avoiding nonlinear distortion of the audio signals, and improving the stability of the audio signals to facilitate long distance transmission.

Description

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