Background
The diaphragm of the traditional micro loudspeaker takes a plastic film as a sound-producing co-whining carrier, which is commonly called as a 'dangling edge'. The magnet is used for electrifying the coil to drive and connect so as to generate the whining and sounding effect, and the plastic material TPE and the plastic film of TPE compounded with other materials are always used as the suspension edge sounding body of the micro-speaker because the current production process limits and the light and thin characteristics are required. The plastic material has the defect of no elasticity, so that the micro-speaker cannot exert a better sound field effect.
Due to the limited size and space of the product, the material of the rubber mould pressing suspension edge of the common traditional loudspeaker monomer can not be used for application. But also the production process precision of the rubber mould pressing suspension edge is not enough. Therefore, the rubber mold pressing suspension edge is not developed and applied to the micro-speaker as a breakthrough in the application and the manufacturing process of the improved micro-speaker.
In view of the above, a technical problem to be solved by those skilled in the art is urgently needed.
