Earphone fixing structure and earphone electroacoustic test fixture comprising same

Abstract

The invention relates to an earphone fixing structure, which comprises a first shell and a second shell, the first shell and the second shell are provided with correspondingly arranged concave spaces, the groove bottom of the first shell is provided with a sound hole, the fixing structure is characterized in that inner concave space of the first shell and the inner concave space of the second shell are combined with each other to form an accommodating space to clamp an earphone to be tested, a sound production hole of the earphone to be tested is opposite to a sound production hole of the first shell, and the split upper shell and lower shell can be combined with each other to fix the earphone; by combining the pressure applying devices combined on the upper shell and the lower shell, the earphone to be tested can be further positioned and fastened, so that the earphone to be tested is accurately fixed, and the sound outlet hole of the earphone to be tested can be better attached to the mounting groove to achieve the testing effect.

Description

technical field [0001] The present application relates to the technical field of audio testing technology, in particular to an earphone electroacoustic test fixture including the earphone fixing structure. Background technique [0002] In the current related technologies, with the rapid development of electronic products such as mobile phones and tablet computers and the continuous improvement of intelligence, the relevant supporting equipment or products (eg, earphones) are also constantly updated to be intelligent. In the earphone industry, earphone acoustic testing is an important part of product quality inspection and a verification method to ensure that the earphone acoustics meet customer standards. Especially with the emergence of TWS (True Wireless Stereo) Bluetooth headsets, the requirements for the sound quality of the headset are getting higher and higher. It is required that the frequency response curves of the left and right headsets should be consistent to enha...

AI Technical Summary

Problems solved by technology

The problem with the test fixture in the related art is: in the area to be tested, there may be a gap between the earphone and the fixture, which will cause air leakage or air leakage during the test; secondly, although the shape of the mounting groove 2 has been as close as possible to the However, due to the wide variety of earphones and the artificial differences in installation work, the earphones may not be placed in the correct position, which will also affect the test results; moreover, due to the development of earphones, it is necessary to Acoustic holes at specific positions are tested, while non-acoustic hole positions need to be wrapped and closed, so the traditional single-side installation can no longer meet the testing requirements of earphones; in addition, with the passage of time, due to the wear and tear of the flexible fixture, the test Accurate confirmation and consistency of results will get worse and worse
