A speaker module

Abstract

The embodiment of the invention provides a loudspeaker module group. The loudspeaker module group comprises a magnetic circuit system, a vibration system and a module group housing for accommodating and fixing the magnetic circuit system and the vibration system. The magnetic circuit system comprises a central magnet for forming a magnetic gap. The vibration system comprises a vibrating diaphragmand voice coils which are disposed at one side of the vibrating diaphragm in a combined manner. The voice coil is suspended in the magnetic gap. The loudspeaker module group has a first end and a second end, wherein the first and second ends are opposite to each other. The sound load of the first end is less than the sound load of the second end. The distance from the voice coil located at the first end to the central magnet is greater than the distance from a voice coil located at the second end to the central magnet. According to the technical scheme provided by the embodiment of the invention, through the adjustment of the distances from a small sound load side and a big sound load side to the central magnet, the loudspeaker module group enables the force applied to the voice coil at the big sound load side to be bigger, and enables the force applied to the voice coil at the small sound load side to be smaller so as to achieve the vibration balance between two sides of the vibrationsystem, thereby effectively reducing the polarization degree caused by the difference of the sound loads at two sides, and improving the performances of a product.

Description

Technical field [0001] The present invention relates to the field of electroacoustic technology, in particular to a speaker module. Background technique [0002] A speaker is a device that can convert electrical energy into sound energy, and is widely used in electronic devices such as mobile phones and computers. In the prior art, when a speaker is assembled with a terminal device, it is usually necessary to place the speaker unit in an external housing and assemble it into the terminal device in the form of a module. [0003] Due to the setting of side sound holes or leakage holes in the housing of the speaker module, the sound load at different positions in the speaker module is different, which in turn causes the vibration system to exhibit polarization. In severe cases, the voice coil may even hit the magnet and make abnormal noises. This phenomenon affects the sense of hearing and user experience. Summary of the invention [0004] The embodiment of the present invention prov...
