Abstract

The invention discloses a phase shift type high-definition wireless audio receiving system. The system is characterized in mainly comprising a processing chip U, a capacitor C12 and a capacitor 13. The anode of the capacitor C12 passes through a resistor R12 and then is connected with the -IN pin of the processing chip U, and the cathode is connected with the GND pin of the processing chip U and is connected to the ground at the same time. The anode of the capacitor C13 is connected with the OUT pin of the processing chip U, and the cathode is taken as an output end. According to the system, an interference signal doped into an audio signal in a wireless transmission process can be filtered at a receiving end and an output end; the double-filtering mode is adopted to filter the interference signal, so that a filtering effect is more thorough, an output audio signal is more clean, the playing quality of sound is improved, and a hearing effect of people is better.

Description

technical field [0001] The invention relates to the field of wireless transmission, in particular to a phase-shifting high-definition wireless audio receiving system. Background technique [0002] The wireless audio signal transmission system consists 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 has brought great convenience to people's lives. With the continuous improvement of people's living standards, people's requirements for sound quality are also getting higher and higher. However, when the wireless audio signal transmission system wirelessly transmits the audio signal, there are usually interference signals doped into the audio signal. Due to the influence of the interference signal, there will be a lot of noise in the sound output at the receiving end. Seriously affect people's hearing effect. Therefore, it is an urgent task to im...
