Problems solved by technology

[0004] However, the above-mentioned adjustment methods are all based on laminar flow control, and the influence of turbulence in the flow process has not been utilized. The cavity of the speaker is still in a relatively fixed state. It can be seen that the current adjustment of the acoustic performance of the speaker lacks flexibility, so It is necessary to provide a new loudspeaker structure

Abstract

The invention provides a speaker system, which is applied to a mobile terminal. The mobile terminal includes a housing, a cover plate, and a speaker system placed in a storage space formed after the cover plate is connected to the housing. The first speaker module on the edges of the two short sides of the casing; the first speaker module includes a first speaker housing with a receiving cavity, a first speaker unit placed in the first speaker housing, and the first speaker unit Close the first valve of the first speaker housing; when an audio signal is input into the first speaker module, open or close the first valve according to the audio signal, so as to increase the resonance frequency of the speaker system or reduce the vibration amplitude of the shell of the mobile terminal. The invention can realize the pressure equalization and damping adjustment of the whole loudspeaker system.

Description

【Technical field】 [0001] The invention belongs to the technical field of loudspeakers, in particular to a loudspeaker system and a driving method based on the loudspeaker system. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of the mobile phone have been diversified, and one of the important functions is the high-quality music function, and the speaker in the mobile phone is one of the necessary conditions for realizing the high-quality music function. [0003] The main function of the leakage hole of the magnetic circuit of the loudspeaker in the related art and the BOX pressure equalization hole of the speaker cavity are to balance the air pressure, and the scheme of damping cloth, lengthening the pipeline, and the cooperation of dust-proof net and f...
