Loudspeaker with cone positioning device and manufacturing method thereof

Abstract

A loudspeaker with a sound cone positioning device and a manufacturing method thereof. The loudspeaker with a sound cone positioning device includes a voice coil, a sound cone assembly, and a centering support. The sound cone assembly includes a sound cone, a sound cone positioning ring, and fixing glue. The sound cone positioning ring includes a fitting edge, an outer folded edge, and a glue seepage hole. The included angle between the extension direction of the outer flange and the central axis of the voice coil is an acute angle or a right angle. The free edge of the sound cone abuts against the joint between the fitting edge and the outer fold, and the fixing glue permeates through the glue hole and fills between the fitting edge, the voice coil and the sound cone, and Between the outer flange and the sound cone. The damper is spaced apart from the sound cone. This loudspeaker ensures that the batch products of the position of the sound cone and the voice coil meet the design requirements, and ensure the consistency of the batch products. At the same time, the bonding area and bonding strength are increased to ensure the reliability of the product.

Description

technical field [0001] The invention belongs to the technical field of sound box equipment, in particular to a loudspeaker with a sound cone positioning device and a manufacturing method thereof. Background technique [0002] The ability of the speaker to produce sound is actually to generate sound waves through the piston movement of the diaphragm, and the generation of piston movement is formed by the interaction between the voice coil and the driving magnet. When the sound passes through the voice coil in the form of current, a correspondingly changing electromagnetic field is generated according to the strength and frequency of the current, and the direction of the magnetic field is determined according to Faraday's right-hand law. The magnetism of the voice coil changes continuously with the change of the current, and interacts with the permanent magnet to generate vibration, which drives the diaphragm to move as a piston, and then emits sounds of different frequencies ...

AI Technical Summary

Problems solved by technology

Since the suspension edge of the sound cone is made of soft elastic material, it is often impossible to quickly and effectively control the position of the sound cone shank fixed on the voice coil during the production process, which will cause the sound cone edge to go up or down. Deformation, which affects the symmetry of the internal and external stiffness coefficients of the entire vibration system, resulting in DC offset and low-frequency distortion increase during the movement of the vibration system under the action of the driving force
