Abstract

A power supply isolated wireless audio receiving device, comprising a DC input connector, a power supply isolation circuit, an audio receiving circuit and an audio output connector, wherein the DC input connector is used to receive the first DC power input from an external power supply; the power supply isolation circuit is used to connect the first The direct current is inverted and rectified into the second direct current and the ground terminals of the first direct current and the second direct current are isolated; the audio receiving circuit is electrically connected with the power supply isolation circuit and connected to the second direct current for wirelessly receiving the sound signal and converting it into Analog audio signal; the audio output connector is used to output the analog audio signal to the external device for sound playback. Since the power supply isolation circuit is set between the DC input connector and the audio receiving circuit, the first DC power input from the external power supply can eliminate the high-frequency interference signal superimposed on itself during the process of inversion and rectification, and avoid high-frequency interference signals. It is transmitted to the audio receiving circuit through a common ground.

Description

technical field [0001] The invention relates to the electronic technical field of audio playback, in particular to a wireless audio receiving device with power supply isolation. Background technique [0002] With the improvement of material conditions, home audio and video entertainment systems and car audio reception and playback systems have gradually become popular. While providing users with a comfortable entertainment experience, some inconveniences have also been exposed. The physical connection between audio equipment and data source equipment The ports are diverse and the connections are complicated. The relevant standards and technical applications in various audio fields are obviously differentiated and incompatible with each other. The current high-fidelity audio equipment has poor flexibility, which makes the power supply connection inconvenient. [0003] At present, many manufacturers use wireless communication technology to optimize the communication connection...
