Electronic product loudspeaker and microphone testing system and testing method

Abstract

The invention relates to the technical field of electronic product loudspeaker test and provides an electronic product loudspeaker and microphone testing system and a testing method. The testing system comprises an airtight box, a voice frequency signal transmit-receive unit and testing terminal; an electronic product, a measurement microphone and a measurement loudspeaker are arranged inside the airtight box; the voice frequency signal transmit-receive unit is used for sending a first voice frequency electrical signal, controlling the measurement loudspeaker to play a first voice frequency signal and obtains a second voice frequency electrical signal; a to-be-tested microphone obtains a first voice frequency signal; a to-be-tested loudspeaker is used for playing a second voice frequency signal; the test terminal is used for transmitting a test control signal to the voice frequency signal transmit-receive unit and receives the second voice frequency electrical signal which is fed back by the voice frequency signal transmit-receive unit, analyzes and compares the first voice-frequency electrical signal and the second voice-frequency electrical signal, stores and outputs a testing parameter, achieves rapid test of the loudspeaker and the microphone of the electronic product. The testing request is high in accuracy due to the fact that the testing parameter is stored through the testing terminal.

Description

technical field [0001] The invention belongs to the technical field of electronic product testing, and in particular relates to a testing system and testing method for loudspeakers and microphones of electronic products. Background technique [0002] In the assembly process of electronic products with speakers (RCV) and microphones (MIC), in order to avoid the situation that the product RCV and MIC have no function after dispensing and assembling the electronic products into a complete machine, the whole product will be disassembled and scrapped, so in During the product assembly process, the RCV and MIC functions of the product are initially tested to ensure that the RCV and MIC of the product can work normally, and the test of the Bluetooth headset is the most common. [0003] At present, the preliminary detection of RCV and MIC functions of electronic products generally adopts the following methods: [0004] (1) The tester blows or speaks to the MIC of the electronic pro...

AI Technical Summary

Problems solved by technology

[0012] The object of the present invention is to provide a speaker and microphone testing system for electronic products, aiming to solve the problem of inaccurate test results, strong subjectivity, and untraceable data caused by manual participation in the detection methods of RCV and MIC functions of electronic products provided by the prior art and the problem of low test efficiency
