| titleOfInvention | Electret loudspeaker |
| abstract | The invention belongs to the technical field of loudspeakers, and particularly relates to an electret loudspeaker which comprises a shell, a first magnetic circuit system and a second magnetic circuit system, wherein a containing cavity is arranged in the shell, the electret loudspeaker also comprises a magnetic conduction vibrating diaphragm, the magnetic conduction vibrating diaphragm is arranged between the first magnetic circuit system and the second magnetic circuit system, and a convex vibration enhancing part is arranged on the magnetic conduction vibrating diaphragm. According to the invention, the first magnetic circuit system and the second magnetic circuit system are arranged, and the magnetic conduction vibrating diaphragm is arranged between the first magnetic circuit system and the second magnetic circuit system, when the first magnetic circuit system and the second magnetic circuit system generate an alternating electromagnetic field, the magnetic conduction vibrating diaphragm vibrates, and the convex vibration enhancement part is arranged on the magnetic conduction vibrating diaphragm, so that the rigidity of a diaphragm vibration area on the magnetic conduction vibrating diaphragm is enhanced, the vibration frequency is further improved, the high-frequency performance of the loudspeaker in the use process is greatly improved, and the high-frequency use requirement of a user is met. |
