Abstract

The invention discloses a signal high-fidelity wireless audio receiving system. The system is characterized by mainly consisting of a processing chip, a capacitor C12, a capacitor C13 and the like, wherein the anode of the capacitor C12, after passing through a resistor R12, is connected with the -IN pin of the processing chip U, the cathode of the capacitor C12 is connected with the GND pin of the processing chip U, the capacitor C12 is grounded at the same time, the anode of the capacitor C13 is connected with the OUT pin of the processing chip U, and the cathode of the capacitor C13 is taken as an output end. According to the invention, interference signals doped in audio signals in a wireless transmission process can be filtered at a receiving end and an output end, the interference signals are filtered by use of a dual-filtering mode, the filtering effect is enabled to be more thorough, the output audio signals are cleaner, the play quality of sound is improved, and the hearing effect of people is enabled to be better.

Description

Technical field [0001] The invention relates to the field of wireless transmission, in particular to a signal high-fidelity wireless audio receiving system. Background technique [0002] The wireless audio signal transmission system is composed of a wireless transmitting system and a wireless receiving system. It is used for long-distance wireless transmission of audio signals. It has been widely used in people's lives and brought great convenience to people's lives. With the continuous improvement of people's living standards, people have higher and higher requirements for sound quality. However, the wireless audio signal transmission system usually has interference signals doped into the audio signals during the wireless transmission of audio signals. Due to the influence of the interference signals, the sound output at the receiving end will have a lot of noise. Seriously affect people's hearing effect. Therefore, it is an urgent task to improve a new type of wireless receiv...
