Now many audio speakers will be coated with a layer of oily glue on the paper cone, this layer of glue is generally damping glue. Why do the paper cones of the audio speakers need to be oiled? Ocean Wave Electronics is here to answer your questions.

Due to some characteristics of the paper cone itself, it is easy to get wet, which leads to the deformation of the paper cone and affects the sound quality of the speaker. Therefore, a layer of oily glue is applied on the paper cone of the audio speaker to achieve the effect of waterproof and moisture-proof, so as to keep the whole paper cone from deformation, and at the same time achieve the purpose of protecting the audio speaker. One of the characteristics of the damping glue itself is that it will not harden all the year round and maintain elasticity, thereby extending the service life of the speaker, and a thin layer will not affect the sound quality of the speaker. In addition, if there is damping glue on the paper cone of the audio speaker, the damping of the audio speaker can be optimized, the rigidity of the speaker diaphragm can be increased, and the distortion can be reduced. Finally, apply oil on the paper cone of the speaker, which can increase the overall appearance of the speaker and make it look more beautiful.

I believe that through the above description, you already know the function of oiling the paper cone of the audio speaker, and you also know where to buy speakers and custom speakers Manufacturer of loudspeakers.
