New description: [New technical field] This creation is related to a kind of composite fabric, especially a high-performance composite fabric used as a damper for loudspeakers and a vibrating membrane edge. . [Prior Art] Press, the basic structure of the speaker (10) is as shown in the first and second figures, and generally includes: - a voice coil (11), when a sound signal current output from the amplifier flows through the voice coil, The variable magnetic field produced by ± is used to drive a vibrating diaphragm (12) to vibrate = vocalization, and an edge (13) acts to fix the vibrating diaphragm (12) to the peripheral surface of the frame; a damper (15) Its function is to make the voice coil (11) move to the center of the magnetic gap without touching the magnetic plate or the yoke (16), and the voice coil and the cone can be in the correct center position when they are at rest. . Therefore, the damper (Μ) is also called a central retainer, and is generally made of cotton and synthetic fibers. However, with the demand of the speaker, the requirements for the damper Gy or the vibrating diaphragm edge (13) are becoming higher and higher, for example, it is necessary to withstand 2 〇 (Γ: high temperature, high strength, high rigidity and fatigue resistance) ·... and other characteristics, otherwise the speaker will become shorter and smaller, and the service life will be shortened, which will affect the original sound reproduction effect and distortion. Therefore, the damper (15) and the edge (13) are now pure cotton ( Cotton) or polyester (P〇lyeSter), the material of T/C blended material, has not met the requirements of high quality. So DuPont and other companies have developed a mixture of aromatic polyamide fibers, because of the required High performance, so it has been used to make dampers or edges. However, these fibers are expensive, and the dampers (15) and edges (13) made of 100% meta-aramid fiber are quality. Good, but the cost is too high, not the average audio can afford. So 50% Cotton and 50% of the meta-aromatic M300939 polyamine fiber made of synthetic fiber, is now widely used in the industry. a fiber-forming, quasi-sexuality is higher than pure cotton, polyester or T/c However, the price is inconvenient, and it is only a simple addition of c〇tt〇n material, so its performance is not as good as 100% meta-aramid fiber; so, there is still room for improvement. Contents】 The main purpose of this creation is to improve the problems of the prior art, to extract/replant s fabrics, and the mussels are lower than the meta-aramid fibers, but have high strength and high rigidity. The characteristics of high temperature resistance and fatigue resistance make the damper and the edge of the composite fabric have the advantage of making the material longer, so as to ensure that the sound can be reproduced without distortion after long-term use of the sound. Objective, the technical means adopted in the present invention comprises: a cloth body; and a strong tough fiber, which is woven in a warp and weft direction in a lattice shape on the body of the cloth. According to the characteristics of the present invention, the composite The fabric can be made into a high-performance damper or a vibrating membrane edge. [Embodiment] Eight first, as shown in the second and fourth figures, the composite fabric (20) package 3 of this creation has: 21), which may be selected from Any of the materials such as cotton, polyester stretch y = r) and the spinning (T/c), or the combination thereof, is limited to this 'these fabrics are of lower quality The material of the damper or the edge is really cheap, and its price is low, which is economical, and it still has a damper or a desired physical property, but it cannot be _ high temperature (2GG ° C), when used -6 - M300939 for a long time, That is, it is easy to degrade the original physical properties, even to the extent that it cannot be used. Therefore, the present invention is to use high-strength and high-toughness fibers (22) on the body (21) of the above-mentioned cloth material, and when weaving the body (21) of the cloth material, That is, the high-strength and high-tough fiber (22) is composited in the warp and weft direction on the main body (21) of the fabric to form the composite fabric (20) of the present invention. The high-strength and high-tough fiber (22) is selected from the group consisting of: meta-aramid fibers (such as Nomex, Conex, etc.) and para-aramid fibers (such as ballistic fibers, Kevlar, Twaron, Technora, etc.). Any one or a combination thereof may be formed, but is not limited thereto, and other high performance fibers equivalent thereto may be used. By means of the high-strength and high-toughness fiber (22), the warp and weft are interwoven on the main body (21) of the fabric, and the amount used is about 5% to 20% of the main body (21) of the fabric, so that the high-performance fiber is used. Although the price is high, but the amount is small, so the cost is not much. However, these composite fabrics (20) have been able to improve their performance, especially by immersing the composite fabric (20) in a resin (not shown), which is combined with a resin composition and then pressed to become the damping shown in the fifth figure. (3〇) or the vibrating membrane edge (40) shown in the sixth figure, the damper (3〇) has a central through hole (3丨) and a disk of a plurality of concentric circles (32); The edge (4〇) is ring-shaped. After testing at temperatures above 2 °C, the strength, rigidity and fatigue resistance are significantly improved compared with the simple fabric body (21). The performance is close to all by the meta-aromatic polyfluorene. Dampers and edges made of amine fibers. For example, the fatigue degree varies depending on the warp and weft density of the high-strength Weaver blade fiber (22), which is between 4.71% and 6.89%, so that the damper (3〇) or the edge (40) has elastic wave fatigue resistance. Good, other strengths and rigidity are relatively improved; therefore, the composite fabric (2〇) of this creation, and the damper (30) and edge (40) made of the composite fabric (20) can be The best balance between price and performance is in line with the needs of the industry. M300939 Please refer to the seventh figure. The composite fabric (20) of this creation can be directly pressed into a damper (30) or edge (40), but if it encounters a large damper (30) or edge (40) When two or more layers can be laminated and pressed into a damper (30) or edge (40), the performance of the elastic wave can meet the requirements. As for the damper (30) and the edge (40) press forming method, it belongs to the technical category of the sound manufacturer, and is not a patent of the original creation. In summary, the structure revealed by this creation is unprecedented, and it can achieve the expected effect, and it can be used for industrial utilization. It fully complies with the new patent requirements, and invites your review committee to grant a patent to encourage Innovation, no sense of morality. However, the drawings and descriptions disclosed above are only preferred embodiments of the present invention. Modifications or equivalent changes made by those skilled in the art in accordance with the spirit of the present invention should still be included in the scope of the patent application. -8- M300939 [Simple description of the diagram] The first figure is an exploded perspective view of the conventional speaker structure.
