Description

Technical Field

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

[0002] With the popularity of smart phones and mobile devices, the market demand for speaker modules continues to increase. At the same time, more and more users want their devices to be waterproof to avoid damage to the device due to accidental water drop during use. For this reason, existing speaker modules need to be tested for waterproof performance.

[0003] Testing the waterproof performance of the speaker module is achieved by testing its air tightness. The existing speaker module testing tooling includes a base, a driving member arranged on the base, and a test block connected to the driving member. The base is provided with a placement slot for placing the speaker module to be tested. The test block is located on one side of the placement slot and is driven by the driving member to approach or move away from the placement slot to contact or move away from the sound outlet of the speaker module to be tested. At present, the side where the sound outlet of most side-sounding speaker modules is located is an inclined surface. However, the inclination of the inclined surface is not necessarily the same in different speaker modules. Therefore, in actual testing, different test heads need to be replaced to adapt to different speaker modules. It can be seen that the existing speaker module testing tooling has the problem of poor versatility. Utility Model Content
