[0002] A speaker, also known as a "horn", is an electroacoustic transducer device that is responsible for converting electrical signals into sound signals. Speakers play an important role in audio systems and are widely used in electronic devices such as sound systems, televisions, computers, and mobile phones. Its working principle is mainly based on electromagnetic induction or piezoelectric effect. In an electromagnetic induction speaker, current passes through a coil to generate a magnetic field, which interacts with a magnet, causing the coil and the connected film to vibrate, thereby producing sound.

[0003] After searching, the patent (application number: 201922477138.1) discloses "a fixture for speaker testing". The device has a simple structure and is easy to use. It only needs to insert the speaker into the cylinder to fix it, saving time and effort. To remove the speaker, you only need to open it. This utility model is equipped with a clearance groove, which is convenient for testing the electrical performance of the speaker. However, the device has the following problems in actual operation:

[0004] Firstly, the device is a single fixture that can only hold one speaker at a time, which results in slow detection efficiency in the assembly line production mode. In addition, the device can only take out materials manually, which is cumbersome, time-consuming and labor-intensive to operate. Utility Model Content

[0023] In this embodiment, a rotation detection method is adopted. A plurality of positioning seats 5 are installed on the cross-connecting frame 4. A loudspeaker can be placed in each positioning seat 5. In the actual detection process, the cyclic detection of the loudspeaker is realized by the rotation of the rotating column 3, which greatly improves the detection efficiency.

[0024] Example 2, refer to Figure 3 A fixture for speaker testing, a first cylinder 6 is arranged on one side of a fixture plate 1, and the piston rod of the first cylinder 6 is connected to a top block 7, a support frame 8 is welded to the outer wall of one side of the fixture plate 1, and a rotating cylinder 9 is fixedly connected to the outer wall of the top of the support frame 8 by bolts, the rotating axis of the rotating cylinder 9 is connected to a second cylinder 10, and the piston rod of the second cylinder 10 is connected to an air clamp 11.

[0025] In this embodiment, the speaker can be directly placed in the positioning seat 5. The size of the speaker is well matched to the positioning seat 5. The speaker can be pushed out of the positioning seat 5 by the first cylinder 6 pushing the top block 7 upward. With the clamping of the air clamp 11, the extension and retraction of the second cylinder 10 and the flipping of the rotating cylinder 9, the speaker can be automatically removed, which is easy to operate and saves manpower.
