Audio detection circuit, audio detection equipment and audio detection system

Abstract

The invention discloses an audio detection circuit, audio detection equipment and an audio detection system. The audio detection circuit is used for being connected with a data acquisition device and a to-be-tested device, the data acquisition device is used for conducting audio testing on the to-be-tested device, and the audio detection circuit comprises a first connection module used for being electrically connected with the data acquisition device; a detection module, wherein one end of the detection module is electrically connected with the first connection module; a second connection module which is electrically connected with the equipment to be detected and the other end of the detection module, wherein the detection module is used for detecting the working state of the to-be-detected equipment, and conducting or turning off the to-be-detected equipment according to the working state. According to the audio detection circuit in the embodiment of the invention, the situation that the audio test is carried out when the to-be-tested equipment is abnormal can be avoided, the problem that a test blind area exists in an audio automatic test method used at the present stage is solved, and the test reliability of the to-be-tested equipment is improved.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to an audio detection circuit, audio detection equipment and an audio detection system. Background technique [0002] At present, the methods for testing audio functions are complex and diverse, and the testing methods generally have the problem of high testing cost or testing blind spots in functional testing. [0003] For example, when performing manual testing, human ears are used to judge whether there is sound output, volume level, and audio level, but this method increases the cost of testing and is affected by human factors, thus forming a blind spot in artificial testing and affecting testing efficiency; One is to use the USB data acquisition card for automated testing, and connect the data acquisition card and the computer through the USB, but the USB connected to the computer can provide an effective bias voltage for the device under test, and cannot intercept th...
