Problems solved by technology

[0003] 1. If the diameter of the cable is too large, it is easy to hinder the flow of air in the module;
[0004] 2. The existing cable lines are all fixed by glue coating, and the fixing effect is not good, resulting in poor consistency of the internal structure of the speaker module
[0005] The above two reasons will lead to a decline in the acoustic performance of the speaker module and poor product consistency

Embodiment Construction

[0030] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention.

[0031] The orientation mentioned in this manual refers to the direction of the vibration system of the speaker unit, and the orientation refers to the direction of the magnetic circuit system of the speaker unit.

[0032] Such as figure 1 , figure 2 and image 3 Commonly shown, a loudspeaker module includes a shell, and the shell is composed of an upper shell 10, a middle shell 20 and a lower shell (not shown in the figure) that are sequentially combined, and the upper shell 10, the middle shell 20 and the lower shell are in common The enclosed space accommodates speaker units. The loudspeaker unit divides the entire module inner cavity into two cavities, the front acoustic cavity and the rear acoustic cavity. The loudspeaker unit, the upper case 10 and the middle case 20 jointly form the front sound chamber of the module. The loudspeaker unit, the middle case 2...

Abstract

The invention discloses a loudspeaker module, which relates to the technical field of electro-acoustic products, and comprises a housing, wherein a loudspeaker unit is accommodated, and the loudspeaker unit is electrically connected to an external circuit of the module through a cable line, and the cable line One end located inside the module is electrically connected to the speaker unit, one end of the cable line located outside the module is electrically connected to the external circuit of the module, and the shell is correspondingly located inside the module The position of the cable line is provided with a positioning groove, the cable line is limited in the positioning groove, and the side wall end faces on both sides of the positioning groove are provided with thermal fuses, and the thermal fuses are thermally fused Finally wrap the cable wire in the positioning groove. The loudspeaker module of the present invention realizes the effective positioning of the cable wires in a limited space, effectively reduces the influence of the cable wires on the airflow in the module, and the product has high acoustic performance and good consistency.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a loudspeaker module. Background technique [0002] The loudspeaker module is an important acoustic component in portable electronic equipment, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. The loudspeaker module usually includes a casing, in which a speaker unit is accommodated, and an electrical connection component for electrically connecting the speaker unit with an external circuit of the module. Because the cable wire (a metal wire with an insulating sheath) has the advantages of strong tensile strength, high reliability and low resistance, and it is very easy to assemble during product assembly, it is currently used to electrically connect the speaker unit and the module Most of the electrical connection parts of external circuits use cable wires, but because portable electronic ...
