Abstract

The invention discloses a microphone tightness test method and a microphone tightness test device. The microphone tightness test method comprises the steps of providing a sound reducing box; placing atest product provided with at least one microphone into the sound reducing box; starting one microphone on the test product, closing the other microphones on the test product to generate test sound in the sound reducing box, and acquiring a normal frequency response value of the started microphone; blocking sound holes, corresponding to the started microphone, in the test product to generate testsound in the sound reducing box, and acquiring a blocked frequency response value of the started microphone; and comparing the normal frequency response value with the blocked frequency response value to acquire a frequency response difference, and judging whether the frequency response difference is more than a preset difference. According to the method provided by the invention, the tightness test can be conveniently performed on the microphone on the test product.

Description

technical field [0001] The invention belongs to the technical field of electronic product testing, and in particular relates to a microphone airtightness testing method and device. Background technique [0002] In recent years, the technology of consumer electronic products has developed rapidly, and the technology applied to earphone products has become more and more complex. Among them, whether it is a music earphone or a Bluetooth earphone for calling, active noise reduction technology has gradually been adopted to improve the user's auditory application experience. [0003] Headphones with active noise reduction technology need to be equipped with a microphone to receive external noise, and then according to the configuration of the software program, active noise reduction can be realized through the sound generating device. The active noise reduction technology has high requirements on the performance of the microphone configured on the electronic product and the runni...
