Testing device and testing method for noise reduction earphone

Abstract

The invention relates to the technical field of earphone noise reduction testing, in particular to a testing device and method for a noise reduction earphone, and the device comprises an isolation box body which is provided with a sealing door used for sealing the isolation box body; the table top is connected into the isolation box body in a displaceable manner through a first adjusting mechanism and can extend out of the isolation box body or be stored in the isolation box body; the earphone placing frame is arranged in the middle of the table top; the loudspeakers are arranged on the two sides of the earphone placing frame in a displaceable mode through second adjusting mechanisms, and the position angles of the loudspeakers can be adjusted relative to the earphone placing frame. Through the arrangement, the table top can be moved into the isolation box body, so that the whole testing device is located in a closed space, the testing result is not influenced by external factors, the accuracy of the testing result is ensured, noise testing in different directions can be carried out on the earphone by moving the position of the loudspeaker, and the testing efficiency is improved. Therefore, the noise reduction function of the earphone is comprehensively tested, and the accuracy of a test result is improved.

Description

technical field [0001] The present application relates to the technical field of earphone noise reduction testing, and more specifically, to a testing device and testing method for noise-canceling earphones. Background technique [0002] With the development of smart earphone technology, more and more consumers are purchasing noise-canceling earphones due to their excellent experience. Noise-cancelling earphones are earphone products that use technical means to reduce noise. The technology is divided into two categories: one is passive noise-cancelling technology that forms a closed space to block external noise through the formation of a good surrounding structure between earmuffs and ears, and the other is Active Noise Cancellation technology that achieves noise reduction electronically. [0003] Passive noise reduction technology mainly isolates the external environment by surrounding the ears to form a closed space, or uses sound insulation materials such as silicone ea...
