[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] During the assembly process of the speaker, rubber material is used for edge pressing. After edge pressing, the speaker has some burrs on the edge and needs to be cut. During cutting, the speaker is usually placed in the specified position manually and removed after cutting. However, the manual loading and unloading method is time-consuming and labor-intensive, and the speaker cannot be placed in place. In addition, there will be some scraps during the cutting process, and these scraps are small in size and are not easy to collect. Utility Model Content
