[0002] With the popularization of mobile devices such as smart phones, the market demand for micro-speakers is increasing continuously, and the performance test requirements for micro-speakers are also increasing. In a micro-speaker test tooling fixture, a pressure probe on a pressing plate will press against a micro-speaker to be tested. When the pressure applied by the pressure probe to the micro-speaker to be tested is different, the performance of the micro-speaker will also be different. However, in the existing micro-speaker test tooling fixture, the pressure probe is fixedly installed on the pressing plate. Therefore, the pressure applied by the pressure probe to the micro-speaker to be tested cannot be adjusted, and thus the influence of pressure on the acoustic performance of the micro-speaker to be tested cannot be measured.
