Abstract

The earphone test method comprises the following steps: placing an earphone sample under a first standard test condition to obtain a first test parameter; placing the earphone sample under a second standard test condition to obtain a second test parameter; obtaining a transfer function according to the first test parameter and the second test parameter; placing the to-be-tested earphone under a second standard test condition to obtain performance test parameters of the to-be-tested earphone; correcting the performance test parameter according to the transfer function to obtain a standard testparameter of the earphone to be tested; calculating an EQ compensation parameter of the earphone to be tested according to the standard test parameter, wherein under a first standard test condition, the earphone sample extends into a test fixture configured with a standard microphone or an ear simulator, and under the second standard test condition, the earphone sample or the earphone to be testedand the standard microphone are arranged at intervals. Also disclosed is an earphone. According to the invention, the performance test parameter is converted into the standard test parameter simulating the real wearing effect according to the transfer function to carry out EQ compensation, so that the consistency of the earphone performance and the standard performance can be fully ensured.

Description

technical field [0001] The present invention relates to the technical field of audio equipment, and more specifically, relates to an earphone testing method and an earphone. Background technique [0002] Any earphone product needs to undergo multiple performance tests before leaving the factory to ensure that the acoustic performance of the earphone monomer is consistent with that of the standard product. [0003] Among them, in the mass production process of semi-in-ear headphones, due to differences in the performance of different speaker units and speaker-related structural components, the individual performance of the headphones is also different from that of standard products, and the performance of the left and right ears of the same headset is also different. In order to make up for individual performance differences or performance differences between the left and right ears, the conventional method is to perform EQ compensation through software, that is, to compensat...
