Abstract

The invention provides a power supply isolated wireless audio receiving device which comprises a direct current input connector, a power supply isolation circuit, an audio receiving circuit and an audio output connector, and the direct current input connector is used for receiving first direct current input by an external power supply; the power supply isolation circuit is used for inverting the first direct current, rectifying the first direct current into second direct current and isolating grounding ends of the first direct current and the second direct current; the audio receiving circuitis electrically connected with the power supply isolation circuit, is connected with the second direct current and is used for wirelessly receiving a sound signal and converting the sound signal intoan analog audio signal; and the audio output connector is used for outputting the analog audio signal to the external playing device for sound playing. Due to the fact that the power supply isolationcircuit is arranged between the direct current input connector and the audio receiving circuit, in the process of inversion and rectification of first direct current input by the external power supply, high-frequency interference signals stacked on the first direct current can be eliminated, and the high-frequency interference signals are prevented from being transmitted to the audio receiving circuit in a common-ground mode.

Description

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