[0002] Speakers are devices that can produce sound and can be found everywhere in our daily lives. The cone as its main structure is crucial to the sound of the speaker. When an audio signal is input into the speaker, the voice coil fixed on the cone vibrates in the magnetic field, forcing the air to resonate and produce sound. Therefore, the stability of the voice coil affects the working state of the speaker.
