Abstract

The invention discloses a low-noise wireless audio transmitting system. The low-noise wireless audio transmitting system is characterized by mainly comprising a processing chip U, a capacitor C8, a resistor R5 and the like, wherein a negative electrode of the capacitor C8 is connected with a GND pin of the processing chip U through a resistor R7; a positive electrode of the capacitor C8 passes through a resistor R4 to serve as an input end of an audio signal; the resistor R5 is connected with the capacitor C8 in parallel. According to the low-noise wireless audio transmitting system disclosed by the invention, the audio signal is processed, and the amplitude of the audio signal is effectively improved, thereby making up the attenuation, generated in a long-distance transmitting process, of the audio signal and improving an auditory effect of a receiving end. Meanwhile, current noise can be eliminated, the interference of the current noise to the audio signal is avoided, the definition of the audio signal is improved, and the transmission quality of the signal is effectively improved.

Description

technical field [0001] The invention relates to the field of wireless transmission, in particular to a low-noise 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, resulting ...
