[0002] In consumer electronic products, speakers and microphones are important sensor devices for the interaction between electronic devices and people. However, due to their high sensitivity during the production process, audio products such as speakers and microphones need to be subjected to factory quality inspections. They are easily interfered with during testing, so special test rooms are set up to shield the interference of external electromagnetic waves. However, testing audio equipment in a shielded room not only takes up a considerable amount of space, increasing the usable area and increasing costs, but also increases the reverberation of the test sound in the space, resulting in inaccurate tests. Furthermore, test staff need to stay in the test room for a long time to operate, which makes them easily affected by the sound and causes certain damage to the eardrum. Utility Model Content
