Abstract

The invention discloses an amplitude-adjustable miniature loudspeaker, which comprises a loudspeaker single body, central magnetic steel is arranged in the loudspeaker single body, the amplitude-adjustable miniature loudspeaker further comprises an electromagnet assembly arranged outside the loudspeaker single body, and the electromagnet assembly is arranged corresponding to the central magnetic steel. The electromagnet assembly is arranged outside the loudspeaker single body. By adjusting the polarity and the magnetic force of the electromagnet assembly, the magnitude of the overall BL driving force of the vibration assembly of the miniature loudspeaker can be changed, so that the vibration assembly of the miniature loudspeaker can reach the rated amplitude, distortion of the miniature loudspeaker during working is avoided, the acoustic performance of the miniature loudspeaker can be guaranteed, and the user experience is enhanced.

Description

technical field [0001] The invention relates to the technical field of electro-acoustic transducers, in particular to a micro-speaker with adjustable amplitude. Background technique [0002] A micro-speaker usually includes a pot frame, a magnetic circuit assembly and a vibrating assembly respectively arranged on the pot frame. The vibrating assembly includes a connected voice coil and a diaphragm. [0003] The amplitude of some existing micro-speakers sometimes fails to reach or exceed the rated amplitude, which will cause sound distortion of the micro-speaker and seriously affect the acoustic performance of the micro-speaker. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a micro-speaker with adjustable amplitude. [0005] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a micro-speaker with adjustable amplitude, including a speaker unit, a ...
