V. Description of the invention (1) The present invention relates to speakers, especially to curved wave plate speakers, such as the speaker published in the international patent application W097 / 09842 and the method for manufacturing the same type of speaker. The speakers are "dispersive" or DM speakers, or simple speakers such as £)] ^ 1 ^. BACKGROUND OF THE INVENTION Most curved wave plate speaker applications use unstructured flat plates. Although these boards are most suitable for producing the highest quality sound effects, these boards also have the need for dual functions. The speaker board is formed in a composite structure. A typical example is a trim panel that acts as a speaker inside a car door. The composite formed plywood is usually made by manually stacking the heat-curable surface mold fish =-layers, but the costs and time related to the manual means that this process can only be used in high-added-value and low-output industries As a result of the space industry and Formula One racing, this technology has not been able to tune the curved wave plate speakers that have yielded.

(It takes 5 to 25 seconds). The main requirement for entering a thermoformable board is the material specifications. Usually these are:…, which can be formed under pressure 1. Thermoplastic surfaces, such as polymer layers or fiber-reinforced polymers. 2 _ Thermoplastic adhesive. 3 · Thermoplastic sandwich, such as foam or nest. The main advantage of this type of board is that the board maker can produce a range of flat plates. This can be used directly as a flat plate or to form a structure. Forming, and: The degree of complexion can range from the formation of the area (such as the formation of the exciter position) to the complete formation of the board (such as the trim plate of the door). The main requirement is that the temperature of the heating surface exceeds its softening point (τ &), and the shackle clip ~ Shaofen is just below the softening point temperature (τ.) Then the board can be formed with a cold mold under grace, where the use The tension frame prevents surface distortion. The complexity of the shape formed after removal depends on the plasticity of the surface. It is mainly determined by the reinforcing material used (see table 丨), especially the amount of Γ sliding between fibers. .It should be noted that this applies to all fiber types (such as carbon, glass, aromatic, natural fibers, etc.). -5- No A 诋 and no weekly T-pictures (CNS) A4 size (210 x 297) Public love)

The hangability of the fiber direction of the machine depends on the weaving method (locking angle). Fiber weaving stretcher / Shi Xi --- J_jingled Fibers are not all fibers. All are suitable when the curved wave board mops are made of continuous fiber cloth. Although these have turned one degree of curvature, their plasticity is severely limited in terms of hyperbola. The reason is that the fiber weave is deformed due to the "lockup" of the fiber chips. This problem can be solved by the use of short fiber chips to reduce the "tension" of the fiber deformation. The soil-reinforced plastic surface can use random short fiber yarns. The advantage of this material in all short-fiber materials is that it can be used at a low weight (-25 gsm), making them more suitable for smaller boards. The main requirement of the sandwich material is that the softening point (Tg) of the sandwich is greater or softer than the softening point of the shame surface. This means that under the correct processing conditions " Ac formation will not damage the structure and make the thickness of the entire forming apparatus uniform. ;,: In some applications, the destruction / compression sandwich can be used to "isolate" the curved wave plate from the main structure.

Description of the invention (4) Thermoplastic layer adhesive can be used in two main forms, namely layer and net. These are often used to fine tune the interior of manufactured automotive equipment, combining fiber threads to the main board. The main requirement when forming triple plywood is to soften at the forming temperature as an adhesive. This is particularly important when using surfaces that limit plasticity, such as continuous fiber cloth, as this allows displacement between the surface and the sandwich. Empirically, carbon polymer sandwich panels have proven their weight and thermoplastic adhesives to reduce the level of cross acoustic waves on the board, and have become a method of controlling the acoustic standing of the board.
