Loudspeaker module

Abstract

The loudspeaker module comprises an elastic piece, a vibrating diaphragm assembly, a driving assembly and a basin stand, the elastic piece further comprises an outer fixing part, a central elastic piece located on the inner side of the outer fixing part and a connecting arm connected with the outer fixing part and the central elastic piece, the outer fixing part is connected with the basin stand, the central elastic piece is connected with the driving assembly, and the central elastic piece is connected with the driving assembly. The central elastic piece is further connected with a transmission part, the vibrating diaphragm assembly is connected with the transmission part, the driving assembly is controlled to drive the central elastic piece and the connecting arm to vibrate, the vibrating diaphragm assembly is driven by the transmission part to synchronously vibrate and produce sound, the connecting arm is further connected with a balance weight, and the compliance of the connecting arm and/or the weight of the balance weight are/is used for adjusting the output characteristic of vibration sound production. According to the loudspeaker module provided by the invention, the output characteristic is adjusted through the elastic sheet and the counterweight, the loudspeaker module is easy to implement in a thin space, and the low-frequency response performance is improved while the medium-high frequency playback quality is ensured, so that the full-band sound playback quality of the loudspeaker is improved.

Description

[0001] This application claims the priority of the Chinese patent application No. 202110097689.4 filed on January 25, 2021, entitled "A Loudspeaker Module", the entire content of which is incorporated in this application by reference. technical field [0002] The invention relates to the field of electroacoustic conversion, and specifically designs a loudspeaker module. Background technique [0003] Existing speaker modules are limited by the space design of the voice coil and magnetic circuit system, and it is difficult to ensure better acoustic performance under the condition of satisfying the thickness condition. When the diaphragm vibrates with large amplitude, it is prone to rocking and rolling vibration, which affects the performance of the speaker. . The piezoelectric speaker can guarantee a certain medium and high frequency sound reproduction, but the low frequency performance is not good. Contents of the invention [0004] In view of this, the object of the prese...

Problems solved by technology

[0003] Existing speaker modules are limited by the space design of the voice coil and magnetic circuit system, and it is difficult to ensure better acoustic performance under the condition of satisfying the thickness condition. When the diaphragm vibrates with large amplitude, it is prone to rocking and rolling vibration, which affects the performance of the speaker.

The piezoelectric speaker can guarantee a certain mid-high frequency sound reproduction, but the low frequency performance is not good.
