Current status of bonding and solidification of micro loudsp

Typical micro loudspeakers generally include sound diaphragm, voice coil, basin frame, magnetic pole, magnetic core, magnetic cylinder and so on. All these small parts are assembled with glue. A small microspeaker sometimes uses as much as eight glues. Because of this, there are people in the industry.

 

 

 

An unwritten statement is that making microspeakers is actually making glue. This proves the role of glue in micro loudspeakers. But it has always been a headache for the industry to make its glue curing quickly. The general curing equipment will release a lot of heat, which will affect the curing process.

 

 

 

The parts of micro loudspeaker are damaged. UVLED irradiator is a kind of cold light source curing machine, which can quickly cure without causing damage to the equipment.

 

 

 

Generally speaking, the bonding of micro loudspeakers can be divided into two parts: the bonding around the magnetic core and the bonding around the sound film. The bonding around the core is the bonding between the core and the pole, the core and the cylinder. Anaerobic adhesives and hot melt adhesives are commonly used. Adhesion around sound film includes sound

 

 

 

Adhesion of membrane and coil, wiring glue and fixing glue, sound film and basin frame, etc. At present, the most efficient adhesive for micro loudspeakers on the market is UV glue. The working principle of UV glue is UV curing or activation, which causes chemical reaction and the process of using UV glue.

 

 

 

Additional ultraviolet curing equipment is needed, which emits ultraviolet light through the ultraviolet curing equipment to make it fast curing.
