[0002] The receiver speaker net is an important part of the receiver assembly of electronic products, such as the receiver net of a mobile phone. The receiver assembly of an electronic product is set inside the electronic product. The shell of the electronic product generally has a sound expansion hole, and the receiver speaker net is installed on the sound expansion hole. The receiver speaker net is provided with a through hole with a very small aperture. The reason for the small aperture of the through hole is that it needs to be dustproof and dirtproof. The sound waves output by the speaker in the receiver assembly are transmitted through the through hole on the receiver speaker net. The receiver net needs to be tested and processed after production. Among them, the sound test after the sound passes through the receiver net is of great significance. It can help evaluate the sound transmission capability of the receiver net, detect performance, ensure that user needs are met, and improve product quality and reliability. Therefore, during the production and use process, volume testing is a necessary step to ensure that the performance and quality of the receiver net meet the requirements.

[0003] Traditional testing equipment usually uses a clamp to clamp the earpiece net. The clamp is used to clamp the earpiece net. Usually, a rotating bolt is used to move the clamp plate, thereby clamping both sides of the earpiece net. The installation and removal of the earpiece net require relatively cumbersome operations. In addition, since the earpiece net of a mobile phone is usually small in size, there is a certain inconvenience in operation. Therefore, a mobile phone earpiece net testing device is proposed to address the above situation. Utility Model Content
