Abstract

An audio circuit arranged in a display includes an audio input connector configured to connect to an audio output connector of a computer to receive audio signals therefrom, an audio input circuit receiving the audio signals, an audio amplifier circuit connected to the audio input circuit to amplify the audio signals, an audio output circuit outputting the amplified audio signals, a first output connector connected to the audio output circuit, a volume adjusting circuit, a micro control unit (MCU) of a motherboard of the display connected to the volume adjusting circuit, and a speaker connected to the first output connector. The volume adjusting circuit receives a control signal from the MCU to control the volume adjusting circuit to adjust the audio signals, and the speaker receives the adjusted audio signals.

Description

technical field [0001] The invention relates to an audio circuit, in particular to an audio circuit for a display. Background technique [0002] At present, most of various displays such as liquid crystal displays do not contain speakers, and the audio signal must be listened to through an external speaker; The audio signal is relatively low, and the sound quality is also poor. At the same time, its circuits are designed on traditional circuits, and the components are used more and the cost is higher. Contents of the invention [0003] In view of the above, it is necessary to provide a display audio circuit with adjustable volume, which effectively solves the difficulty of not being able to adjust the volume when listening to audio signals. [0004] A display audio circuit, comprising an audio circuit and a loudspeaker, the audio circuit comprising an audio input connector, an audio input circuit, an audio amplification circuit, an audio output circuit, a first audio outp...
