Abstract
The invention provides a sound detection apparatus for an automobile electronic control unit, relates to a sound detection apparatus, belongs to the detection field, and aims at solving problems of low efficiency and poor accuracy of manually detecting sound quality of a to-be-detected automobile instrument. The sound detection apparatus comprises a core processor, an audio signal acquisition module, a memory module, a power supply module and a display. The power supply module is used for supplying power. The audio signal acquisition module acquires sound signals of a to-be-detected automobile electronic control unit, and outputs the sound signals to the core processor. An audio memory signal output end of the core processor is connected with an audio memory signal input end of the memory module. An audio acquisition control signal output end of the core processor is connected with an audio acquisition control signal input end of the audio signal acquisition module. A display signal output end of the core processor is connected with a display signal input end of the display. A power receiving end of the power supply module is connected with a power supplying end of an external power supply. The sound detection apparatus is used for detecting sound during the operation of the automobile electronic control unit.
