Abstract

The invention discloses a voice detection method, device and system of display equipment. The display equipment comprises a signal source interface. The voice detection method includes following steps: acquiring audio frequency output by the display equipment and collected by an audio frequency collection device, wherein the audio frequency output by the display equipment is generated on the basisof an audio frequency detection signal input to the signal source interface; analyzing the audio frequency collected by the audio frequency collection device to acquire a voice detection result. Thedisplay detection method can replace workers to detect the display equipment to avoid manual detection errors like missing detection and mistaken detection.

Description

technical field [0001] The present invention relates to the field of equipment detection, and in particular, to a method, device and system for sound detection of 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 the screen, but also play sound at the same time. In particular, LCD screen display devices such as televisions are usually equipped with a sound playing device, and the sound playing device plays the sound according to the received various video or audio signal sources. When the display device has been assembled and tested before leaving the factory, it is generally the workers who test each signal source interface and function of the display device one by one in the assembly line. There is no real objective testing standard for whether the equipment is qualified or ...
