Description

Elastic wave mold and elastic wave molding product with inner and outer boosting areas Technical Field The present utility model relates to a wave mold and a wave molded product, and more particularly, to a wave mold for hot press molding a wave molded product on a substrate and a wave molded product having an inner and outer booster areas. Background A general moving coil type loudspeaker generates sound by utilizing the principle that the reaction force of a fixed magnetic field makes the other magnetic field move in opposite directions (i.e. opposite attraction and opposite repulsion). Further, the power alternating current generated by the power amplifier is transmitted to the voice coil through the lead wire to change the polarity of the magnetic field, so that the voice coil generates a reaction force relative to the fixed magnetic area generated by the magnetic return device. Positive pulses cause outward movement of the diaphragm relative to the magnet and negative pulses cause inward movement of the diaphragm relative to the magnet. When the voice coil pushes the diaphragm to reciprocate, the diaphragm pushes air, and the air pressure changes to form sound waves. The spring wave is used for keeping the voice coil at the correct position in the gap of the iron core of the magnet, so that the voice coil can reciprocate along the axial direction when being stressed. The suspension edge is arranged between the vibrating diaphragm and the outer frame and used for supporting the vibrating diaphragm. The conventional method for manufacturing the wire elastic wave comprises the following steps of combining and weaving a plurality of warps, a plurality of wefts and a plurality of wires into a base material, immersing the base material in a resin solution, drying the base material, heating and pressurizing a wire elastic wave forming block of the base material to form a wire elastic wave, and separating the wire elastic wave from the base material. However, since the shrinkage force of the wire elastic wave forming block is dispersed on the whole substrate when heated and pressurized, the degree of the wire elastic wave forming block bearing the shrinkage force cannot be controlled, and the deformation degree of the wire elastic wave cannot be controlled. Furthermore, the existing wire bullet wave manufacturing method is automatic and continuous, and the base material has certain elasticity, so that each flat wire bullet wave forming block can be wrinkled into a wave-shaped wire bullet wave in the heating and pressurizing process, and the shrinkage force can pull each subsequent wire bullet wave forming block to move forwards for a certain distance, so that the positions of the plurality of wire bullet wave forming blocks which are not formed in the follow-up process can slightly deviate from the original preset positions. Therefore, the hot press forming device can form the wire elastic wave at the position slightly deviated from the position of the plurality of wire elastic wave forming blocks which are not formed later, but not completely form the wire elastic wave at the position of the plurality of wire elastic wave forming blocks which are not formed later originally, so that the interval distance of the plurality of wire elastic waves formed later is larger than the preset value. Since the substrate between two adjacent wire springs will form waste, the above problem will generate more waste than originally imagined. In addition, when the two wire elastic wave forming blocks are continuously formed into two wire elastic waves, yarns between the wire elastic wave forming blocks are simultaneously pulled and broken by two shrinkage forces, so that the base material is further torn. Disclosure of utility model The utility model mainly aims to provide a spring wave die and a spring wave molding product with an inner and an outer boosting areas, which can control the degree of the wire spring wave molding block bearing the shrinkage force and achieve the purpose of controlling the deformation degree of the wire spring wave. Another object of the present utility model is to provide a damper mold and a damper molding product having an inner and outer booster region, which can ensure that the position of the wire damper molding block remains unchanged. It is still another object of the present utility model to provide an elastic wave mold and an elastic wave molded product having an inner and outer pressurizing area, in which the substrate is not torn. In order to achieve the above-mentioned objective, the present utility model provides an elastic wave mold, which includes a pressing mold and a forming mold. The pressing die comprises a pressing surface, the pressing surface comprises an upper body forming part, an upper wire elastic wave forming part, an outer boosting area lug and a plurality of inner boosting area lugs, the upper wire elastic wave forming part is arranged on the inner side of the upper bod
