Loudspeaker module

Abstract

The invention discloses a loudspeaker module, and belongs to the technical field of audio-video equipment. The module comprises: a first cavity; a second cavity which is arranged adjacent to the firstcavity; and a vibration module which is arranged in the first cavity, wherein the vibration module comprises a first vibrating diaphragm and a second vibrating diaphragm which are horizontally arranged at intervals. The first cavity comprises a first sub-cavity and a second sub-cavity which are located on the two sides of the vibration module respectively, and the second sub-cavity is communicated with the second cavity. According to the loudspeaker module provided by the invention, the condition that sharp peaks and valleys exist in a medium-high frequency curve can be improved, and a good hearing feeling is achieved; the arrangement of a powder net structure can increase the ventilation capacity between the second sub-cavity and the second cavity and prevent foreign matters in the product from contacting the second vibrating diaphragm to influence the tone quality, and a rear cavity is directly arranged below the second vibrating diaphragm, so that the design compactness of the product is improved, the space of the rear cavity is greatly increased, the low frequency is further improved, the product quality is improved, and the medium-high frequency adjusting function of the second vibrating diaphragm is not influenced.

Description

technical field [0001] The invention relates to the technical field of audio-visual equipment, in particular to a loudspeaker module. Background technique [0002] At present, the entertainment audio-visual equipment is provided with speakers to play the sound in the entertainment audio-visual equipment, and with the update of the size of the entertainment audio-visual equipment, there is a higher requirement for the size of the speakers. [0003] In the prior art, a loudspeaker usually includes a casing and a vibration module disposed in the casing, wherein the vibration module includes a diaphragm, a voice coil, and a magnetic circuit system. At present, due to the limitation of the internal space of the mobile phone and the requirements of the thickness of the speaker, most of the built-in speaker modules of the smart phone are side-firing sound, so there will be a problem, the mid-high frequency curve will have a sharper mid-high frequency due to the resonance of the fro...

AI Technical Summary

Problems solved by technology

At present, due to the limitation of the internal space of the mobile phone and the requirements of the thickness of the speaker, most of the built-in speaker modules of the smart phone are side-firing sound, so there will be a problem, the mid-high frequency curve will have a sharper mid-high frequency due to the resonance of the front cavity Acoustic peaks and valleys. At this time, the sound from the speaker is harsh, resulting in poor hearing experience for the user, which in turn leads to low practicality and applicability of the speaker.
