[0002] A speaker is an electroacoustic transducer that can convert electrical signals into sound signals and radiate them into the air. Traditional speakers are divided into electric, electromagnetic, electrostatic, piezoelectric, ionic and pneumatic types according to their working principles. With the rapid development of electronic technology, more and more electronic products use speakers as sound-generating devices. Existing speakers have certain disadvantages when used. Existing speakers will generate certain vibrations when used. When the speaker vibrates and collides with the outer casing or dust cover, it will generate certain noise, affecting the quality of the speaker, which is relatively inconvenient.
