[0002] A loudspeaker, also known as a "horn", is a transducer device that converts electrical signals into sound signals. The performance of the loudspeaker has a great impact on the sound quality. The loudspeaker is an electroacoustic transducer that can convert electrical signals into sound signals and radiate them into the air. Traditional loudspeakers are divided into electric, electromagnetic, electrostatic, piezoelectric, ionic and pneumatic types according to their working principles. At present, the existing loudspeakers are prone to dust being contaminated on the diaphragm during long-term use. The long-term accumulation of dust can easily affect the sound quality during the use of the loudspeaker.
