Description

Technical Field

[0001] The utility model relates to the technical field of electroacoustic converter testing devices, and particularly relates to a testing tooling for a speaker module. Background Art

[0002] With the rapid development of portable mobile devices such as smart phones, more and more users hope that portable mobile devices have better sound quality. To solve this pain point, a new type of speaker module has emerged on the market (as Figure 1 shown), and this speaker module includes a module housing 1 and two speaker units 2 provided in the module housing 1.

[0003] However, the speaker module needs to be subjected to a sound emission test. Since the above-mentioned speaker module has two sound outlets 11, when using the existing testing tooling to test the speaker module, two sets of testing tooling need to be prepared. After the sound emission test of one speaker unit in the speaker module is completed, the speaker module needs to be removed from this testing tooling and then assembled to another testing tooling for the sound emission test of another speaker unit. The entire testing process is very cumbersome and complex, seriously affecting the testing efficiency, and the tooling preparation cost is also relatively high. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a testing tooling for a speaker module that can improve the testing efficiency and reduce the equipment cost.
