Problems solved by technology

However, the thermal conductivity of the adhesive is low, and the heat generated in the voice coil bobbin cannot be smoothly transferred from the adhesive to the cone and dust cap, so that the heat cannot be transferred from the top of the speaker
Overheating inside the speaker will cause problems such as demagnetization of the magnetic circuit and structural deformation, which will seriously affect the sound quality of the speaker
On the other hand, the adhesive is different from the material of the diaphragm, voice coil frame, and dust cap, and the strength of the bonding position is also different. This difference will cause defects in the sound quality of the speaker.
Such problems cannot meet the high sound quality requirements for speakers

Abstract

The invention relates to a loudspeaker device. The loudspeaker device comprises a shell, a magnetic circuit system, a vibrating diaphragm, a voice coil skeleton and a dustproof cap; the magnetic circuit system is installed on the shell for generating a magnetic circuit system of a magnetic field; the vibrating diaphragm is installed on the shell, and an opening is formed in the middle of the vibrating diaphragm; the voice coil skeleton is fixedly installed on the opening of the vibrating diaphragm, and suspended in the shell, and a first joining seam is formed between the voice coil skeleton and the vibrating diaphragm; the dustproof cap is fixedly installed on the vibrating diaphragm to cover the open of the vibrating diaphragm, and a second joining seam is formed between the dustproof cap and the vibrating diaphragm; the first joining seam and / or the second joining seam are joined in an intermittent welding manner, and an adhesive is coated on the first joining seam and / or the second joining seam joined in the intermittent welding manner; the dustproof cap is used for separating the upper side from the lower side of the vibrating diaphragm. The loudspeaker device provided by the invention is capable of improving the sound quality of the loudspeaker, and enhancing the heat dissipation.

Description

technical field [0001] The invention belongs to the technical field of acoustic-electrical energy conversion, and in particular relates to an improvement in the structural design of a speaker device. Background technique [0002] A speaker device is an important device in the field of acoustic-electrical conversion technology. From tweeters to micro speakers, those skilled in the art usually use a moving coil speaker device as a sound-generating element. In the existing moving coil loudspeaker, especially in the horn, the sound-emitting diaphragm is usually composed of a paper or fiber ring and a cone. Inside the speaker, there is a voice coil skeleton connected with the cone and suspended in the magnetic field. The voice coil skeleton generates vibration through the electromagnetic induction effect, thereby driving the diaphragm to vibrate and produce sound. Usually, a person skilled in the art evenly coats the adhesive at the connection between the cone and the voice coil...
