Abstract

The invention provides a noise canceling earphone testing device and a noise canceling earphone testing system, a microphone fault diagnosis device, a microphone fault diagnosis system and a microphone fault diagnosis method thereof. The testing device comprises a base, a vertical plate and a fixing frame, wherein the vertical plate and the fixing frame are both mounted on the base; the fixing frame is used for supporting the head beam of the noise canceling earphone to be tested; and the vertical plate is used for fitting the earphone cover of the noise canceling earphone to be tested. The testing device is used to fix the noise canceling earphone to be tested, and ensure the stability and reliability of the test data obtained by the earphone to be tested during the testing process, and the test device has the advantages of simple structure, easy realization, and low cost. The testing system consisting of the testing device and the data collecting device and the computing device is capable of acquiring the transfer function of the acoustic characteristics of the noise canceling earphone based on the acoustic characteristic data of the noise canceling earphone collected, thereby laying a foundation for the filter design of the noise canceling earphone.

Description

technical field [0001] The present invention relates to the field of active noise reduction, in particular to a noise reduction earphone testing device and system, a microphone fault diagnosis device, system and method thereof. Background technique [0002] The core technology of active noise-cancelling headphones (hereinafter referred to as noise-cancelling headphones) lies in the design of filters with excellent noise-cancelling effects. The filter is designed based on the acoustic characteristics of active noise-cancelling headphones. The acoustic characteristics of the noise canceling earphone need to determine the acoustic transfer function of the main channel and the secondary channel. Since different noise-canceling headphones use different components, such as speakers with different impedances and transfer coefficients, and the elastic pads and front and rear acoustic cavities of each noise-canceling headphone are different, the acoustic transfer functions of differe...
