Audio test fixture for headphone

Abstract

The invention discloses an audio test fixture for a headphone. The audio test fixture for a headphone comprises left and right earpieces with symmetrical structures, each earpiece comprises a coupling fixture and an artificial ear, and the coupling fixture is provided with a coupling cavity for accommodating a headphone earmuff to be tested; the artificial ear is connected with the coupling fixture in interference fit, and the annular edge of the front cavity of the artificial ear and the attachment plane of the headphone earmuff to be tested and the coupling fixture form a plane. According to the technical solution, the audio test fixture is simple in structure, and can well position the headphone earmuffs, effectively avoid extrusion deformation of foam in the headphone earmuffs during testing, eliminate the influence of the difference between the left and right earpieces thereof on the headphone clamping force balance, control the difference of test results due to repeated pick and place, reduce retest and improve the test first pass yield and efficiency of the headphone; the audio test fixture is convenient to pick and place; and when the headphone is tested, the left and right earmuffs of the headphone are fixed via the clamping force of the headphone, so that the situation that the headphone is worn on ears is truly reflected.

Description

technical field [0001] The invention relates to audio testing tooling, in particular to an audio testing tooling for earphones. Background technique [0002] With the advancement of technology and the popularization of electronic products, consumers have higher and higher requirements for products. Especially people also more and more higher to the quality requirement of headset product. Not only is it required to have clear high, medium and low levels and theater-like sound quality performance, but also requires the product to have a beautiful appearance and good wearing comfort, and it will not cause fatigue under long-term use. feel. [0003] In order to meet consumers' requirements for comfort, a circle of foam with a thickness of more than 6 mm will be added to the earmuffs of the headset as the inner village, and the earmuffs made of comfortable cloth or soft leather and protein silk leather will be added. cover etc. The design of this type of earmuffs can make the...

AI Technical Summary

Problems solved by technology

[0006] In view of the fact that the audio test tooling for headphones in the prior art cannot effectively avoid the extrusion and deformation of the foam in the earmuffs of the earphones, nor can it position the earmuffs well during the test, and it is difficult to ensure that the earphones are repeatedly taken and placed. The problem of the consistency of the result proposes a kind of audio frequency test equipment of headphone of the present invention, so that solve or at least partly solve the above-mentioned problem
