Abstract

The invention discloses a sound detection method, device and system of a display device, wherein the sound detection method of a display device includes a signal source interface, and the sound detection method includes the following steps: The audio output by the display device, the audio output by the display device is generated based on the audio detection signal input to the signal source interface; the audio collected by the audio collection device is analyzed to obtain a sound detection result. The display detection method provided by the present invention can replace workers to detect display devices, so as to avoid manual detection errors, such as missed detection, false detection and the like.

Description

technical field [0001] The invention relates to the field of equipment detection, in particular to a sound detection method, device and system for display equipment. Background technique [0002] Display devices are used to display various information, and are widely used in office, teaching, entertainment, business presentations, etc. However, the existing display devices can not only display on the screen, but also play sound at the same time. In particular, liquid crystal display devices such as televisions are usually equipped with sound playing devices, which play according to receiving multiple video or audio signal sources. When the display device has been assembled and tested before leaving the factory, workers generally test each signal source interface and function of the display device one by one in the assembly line. The sound detection mainly depends on the subjective judgment of the sound played by the display device. Whether the equipment is qualified can le...
