Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and particularly relates to a loudspeaker housing. Background Art

[0002] A loudspeaker is a device that converts electrical signals into sound waves and is widely used in audio systems, televisions, mobile phones, etc. Its main components include a vibration system, a magnetic circuit system, and a housing. The vibration system consists of a diaphragm, a voice coil, and a bracket, which is responsible for converting electrical signals into mechanical vibrations; the magnetic circuit system includes a permanent magnet and a pole piece, which provides a stable magnetic field; the housing protects the internal components and optimizes the sound quality.

[0003] Mounting holes are usually provided on the loudspeaker housing for aligning the various components of the loudspeaker. A mounting rod is arranged in the mounting hole for fixing between the loudspeaker housing and the components. To improve the assembly effect of the loudspeaker housing and other components, the mounting rod is heated by a heating element, and the heat emitted by the mounting rod melts the loudspeaker housing, so as to make a tighter connection between the loudspeaker housing and the mounting rod.

[0004] However, when the mounting rod heats the plastic housing, the heat will dissipate from the disc of the mounting rod, resulting in poor effect of the mounting rod melting the loudspeaker housing. The resulting heat loss will cause gaps to appear at the connection between the outer surface of the mounting rod and the side wall of the mounting hole, resulting in a loose connection between the mounting rod and the loudspeaker housing. The mounting rod is prone to movement or misalignment, resulting in loosening of the overall structure of the loudspeaker housing, thus affecting the assembly concentricity and height of the loudspeaker housing and being unfavorable for the subsequent assembly work.
