[0002] The emergence of earphones has brought great convenience to people's work. Among them, TWS earphones are widely popular because they are free from the bondage of wires, greatly improving convenience and portability. To ensure the use quality of TWS earphones, tests need to be carried out during the R & D and production stages, such as active noise cancellation test (ANC test), microphone test (MIC test), and speaker test (SPK test). To simplify the test process and save labor, the above - mentioned tests are carried out at the acoustic test workstation, but the current automation of the acoustic test workstation still has deficiencies. Traditional operations require staff to manually put the earphones to be tested into the automatic test device, clamp them and turn on the machine, and then turn off the machine and take them out after the test. The production volume of earphones is generally large, while the number of earphones that can be tested simultaneously by a single test device is small. When there are many test items to be carried out, the number of test devices involved is also large. The repeated labor intensity of the staff is high and the test efficiency is low. At the same time, the transfer time of earphone products between multiple devices is long, further reducing the efficiency.
