The diaphragm of the pitch sound membrane of the loudspeaker is one of its key components, which directly affects the performance of sound quality and volume. In the production and maintenance of loudspeakers, it is very important to choose the appropriate glue for adhesive the diaphragm sound film to the diaphragm frame of the horn. This paper will introduce how to select the glue, and recommend the use of high-performance environmentally friendly water-based adhesive for bonding.

 When choosing a glue, the first thing to consider is the stability and bonding properties of the glue. The diaphragm sound film of the loudspeaker needs to withstand the higher frequency and amplitude, so the adhesive strength of the glue needs to be high enough. In addition, the glue should have good weather resistance and high temperature resistance to ensure that the diaphragm sound film can work steadily for a long time.

 Secondly, the first choice of the diaphragm sound film material harmless and environmentally friendly glue. The EG 206 is just one such option. Its main material is a kind of water-soluble modified polyurethane material, non-toxic, odorless, harmless and low VOC (volatile organic compound) glue, used without obvious smell, will not produce harmful gas, are very safe to the human body and the environment. In addition, this glue also has excellent bonding properties and anti-aging properties, which can ensure that the diaphragm diaphragm is stably adhered to the diaphragm frame of the horn for a long time.

 Another important reason for choosing this glue is that it is suitable for different materials of diaphragm sound film. The common materials are paper, rubber, polyester fiber and aluminum. This glue has excellent adhesive performance, and can be well applied for these different materials of the diaphragm sound film, to ensure that the adhesion is firm without damaging the diaphragm sound film.

 The following points are noted when using this glue for bonding. First, the surface of the diaphragm and the frame should be clean and dry to improve the bonding effect. Secondly, evenly apply the glue on the contact surface of the diaphragm sound film and the diaphragm frame to avoid the overflow of excess glue. Finally, the diaphragm sound film is gently pressed onto the diaphragm frame to ensure that the glue evenly covers the whole contact surface, and then placed for a certain time to ensure the curing and adhesive strength of the glue.

 In conclusion, choosing the right glue is very important for the diaphragm sound membrane of the loudspeakers. ENIENT Waterborne diaphragm adhesive is an ideal choice, it not only has excellent bonding properties and anti-aging properties, but also is very safe and environmental protection. The use of this glue bond can ensure that the diaphragm sound film works steadily for a long time, providing a solid guarantee for the sound quality and performance of the loudspeaker.
