[Prior Art] The flat-type speaker n is mainly composed of a frame, a sounding vibration plate, a vibration device and a suspension edge, wherein the sounding vibration plate is connected to the frame by a suspension edge and is driven by a shock absorber. In the reciprocating vibration, the sound is oscillated by the sounding vibration plate to form a sound wave 'according to the change of the sounding plate vibration rate and amplitude' to generate sound of various frequencies. I know that there are two main types of sounding vibration plates for flat-panel speakers. One is a wooden sandwich panel. The other is a foamed plate. The sandwich plate is made of a thin clip-shaped plate made of wood as a substrate and on the surface of the substrate. The coating resin forms a waterproof layer, and the water-repellent layer is used to block moisture, thereby preventing the wooden substrate from being deformed by moisture; the foamed board is made of a plastic foamed board as a substrate, and is sandwiched between the two carbon fiber sheets on the substrate by the carbon fiber board Avoid deformation and damage of the substrate to extend the service life. The sounding vibration plate made of the foamed board is made of a heterogeneous material made of the foamed board, and the carbon fiber board is made of a heterogeneous material, and the adhesive is adhered therebetween, and the strength is not good, and the substrate and the carbon fiber board are between the substrate. It is easy to peel off due to vibration. Once the substrate and the carbon fiber board are peeled off, the peeling part cannot be synchronized with the main body of the vibrating plate during vibration and sound generation, and the sound of the sound of the sound is affected by the sound of the sound of the speaker. The vibrating plate made of wood board, because the wood board is an anisotropic material, the rigidity of the fiber direction is perpendicular to the direction of the vertical fiber, and the surface of the board becomes a discontinuous surface due to the void, resulting in a decrease in the strength and strength of the board. When the vibration sounds, the wooden board is prone to deformation, or even cracks due to too much deformation, affecting the sounding effect. Please refer to the first 'When the vibrating plate vibrates, the vibrating plate is generally body-shaped from the low range to the middle range. Movement back and forth, however, due to insufficient rigidity and strength, the vibrating plate is easily deformed, so that the plate is moved early, so it arrives At a certain frequency of the range, the vibrating wire will be in the opposite part of the opposite edge (Edge), which will produce a reverse phase motion with the (4) part, so that the sound pressure of the itj sound is reduced' on the solution curve. , the depth of the valley, and the so-called "Woyin Valley", its sound quality is not ideal. If the resin is sewed on the vibrating board, the resin can be made from the pores on the surface of the board to increase the weight of the board, thereby reducing the sounding efficiency of the vibrating board. In response to the above-mentioned shortcomings, the inventors actively carried out research and creation, and after many trials, finally obtained the invention which is innovative and available for industrial use. SUMMARY OF THE INVENTION The main object of the present invention is to provide a vibrating plate structure of an i-shoe, which is coated on a surface of a substrate by using a resin having micro and navel green, and the surface of the substrate is formed by a micro or a nephew. According to this, the rigidity and strength of the vibrating plate are improved, and the effect is lowered. The invention relates to a sounding vibration board structure of a speaker, which mainly comprises a core board and a surface layer, wherein the core board is a thin light and light board made of wood, and the surface layer is coated with a rouge paint on the Wei surface. _成, according to the protection of 1307610 the core board; the resin coating is composed of 1~50% by weight of high-strength particles and 99~5〇% by weight of high-molecular polymer 'according to high-strength particles filled into the core The surface of the plate surface is such that the surface of the core plate forms a continuous surface without voids, thereby improving the rigidity and strength of the core plate, and by using the surface layer to improve the flexibility of the surface, and for reducing the effect of the middle valley effect.
