Specifically, the adjacent carbon nanotubes are combined with U by van der Waals force to form the self-supporting carbon nanotube film structure. The plurality of amorphous carbon particles 1631 (Amorphous carbon) are combined by a covalent bond to form an amorphous carbon structure 163. The so-called "self-supporting structure" means that the carbon nanotube film structure 162 can maintain its own specific shape without being supported by a support. Since the large number of carbon nanotubes in the self-supporting carbon nanotube film structure 162 are attracted to each other by the van der Waals force, the carbon nanotube film structure 162 has a specific shape to form a self-supporting structure. The carbon nanotube film structure 162 may be a film structure formed by at least one carbon nanotube film shape 098143546 Form No. A0101 Page 8 / 28 pages 0982074602-0 201123933, when the carbon nanotube film structure 162 includes When the carbon nanotube film is complex, the plurality of carbon nanotube films are stacked, and the adjacent carbon nanotube film is combined by van der Waals force. The carbon nanotube film can be a carbon nanotube film, a carbon nanotube film or a carbon nanotube film. [0022] The carbon nanotube film structure 162 may include at least one carbon nanotube film, which is obtained by directly pulling from a carbon nanotube array. Supportive nano carbon tube film. Each nano carbon tube film comprises a plurality of carbon nanotubes which are substantially parallel and parallel to the surface of the carbon nanotube film. Specifically, the plurality of carbon nanotubes are connected end to end by van der Waals force and are preferably aligned in the same direction. The preferred orientation means that most of the carbon nanotubes in the carbon nanotube film have a large orientation probability in a certain direction, and the preferred orientation can also be understood that the axial direction of the majority of the carbon nanotubes extends substantially in the same direction. It can be understood that a large number of carbon nanotubes in the self-supporting carbon nanotube film are attracted to each other by Van der Waals forces and are connected end to end by Van der Waals force, so that the carbon nanotube film has a specific shape. Forming a self-supporting structure. The carbon nanotube segments have any width, thickness, uniformity, and shape. The thickness of the carbon nanotube film is 0.5 nm to 100 μm, and the width is related to the size of the carbon nanotube array for pulling the carbon nanotube film, and the length is not limited. When the carbon nanotube film structure 162 comprises a stacked multi-layered carbon nanotube film, a preferred angle between the adjacent two layers of carbon nanotube film forming an intersection angle α is formed between the carbon nanotubes. α is greater than or equal to 0 degrees and less than or equal to 90 degrees. A gap is formed between the plurality of carbon nanotube films and/or one of the adjacent carbon nanotube films, thereby forming a plurality of micropores in the carbon nanotube film structure 162. 1621, the aperture 098143546 of the micro hole 1621 form number Α 0101 page 9 / total 28 page 0982074602-0 201123933 is less than ίο micron. [0024] The carbon nanotube membrane structure 162 can be a carbon nanotube flocculation membrane, which is a self-supporting nanocarbon obtained by flocculation of a carbon nanotube raw material. Tube membrane. The carbon nanotube flocculation membrane comprises carbon nanotubes which are intertwined and uniformly distributed. The length of the carbon nanotubes is greater than 10 microns, preferably between 200 microns and 900 microns, thereby allowing the carbon nanotubes to entangle each other. The carbon nanotubes are attracted and distributed by Van der Waals forces to form a network structure. Since the large number of carbon nanotubes in the self-supporting carbon nanotube flocculation membrane are attracted to each other and entangled by van der Waals force, the carbon nanotube flocculation membrane has a specific shape to form a self-supporting structure. . The carbon nanotube film is isotropic. The carbon nanotubes in the carbon nanotube flocculation membrane are uniformly distributed and randomly arranged to form a large number of microporous 1621 structures, and the micropores 1621 have a pore size of less than about 10 μm. The length and width of the carbon nanotube film are not limited. In the carbon nanotube flocculation film, the carbon nanotubes are intertwined with each other, so the carbon nanotube flocculation film has a good flexibility, and is a self-supporting structure, which can be bent and folded into an arbitrary shape without breaking. . The area and thickness of the carbon nanotube flocculation film are not limited, and the thickness is 1 micrometer to 1 mm, preferably 100 micrometers. The specific structure of the carbon nanotube flocculation membrane and the preparation method thereof are described in Taiwan Patent Application No. 200844041, published on Nov. 6, 2008. To save space, reference is made only to this, and all technical disclosures of the application should be considered as part of the technical disclosure of the present application. [0025] The carbon nanotube membrane structure 162 can be a carbon nanotube rolled membrane, which is a self-supporting nano-particle obtained by rolling a carbon nanotube array. Carbon tube membrane. The carbon nanotube rolled film comprises a uniform distribution of 098143546 Form No. A0101 笫 10 pages / 28 pages 0982074602-0 201123933 of carbon nanotubes, the carbon nanotubes are arranged in the same direction or in different directions. The carbon nanotubes in the carbon nanotube rolled film partially overlap each other and are attracted to each other by the van der Waals force, so that the carbon nanotube film structure 162 has good flexibility and can be bent and folded. In any shape without breaking. Moreover, since the carbon nanotubes in the carbon nanotube rolled film are attracted to each other by the van der Waals force, the carbon nanotube film is a self-supporting structure. The carbon nanotubes in the carbon nanotube rolled film form an angle /3 with the surface of the growth substrate forming the carbon nanotube array, wherein the angle is greater than or equal to 0 degrees and less than or equal to 15 degrees, and the angle is applied to 0 The pressure on the carbon nanotube array is related. The larger the pressure, the smaller the angle. Preferably, the carbon nanotubes in the carbon nanotube rolled film are arranged parallel to the growth substrate. The carbon nanotube rolled film is obtained by rolling a carbon nanotube array, and the carbon nanotubes in the carbon nanotube rolled film have different arrangement depending on the manner of rolling. Specifically, the carbon nanotubes may be arranged in disorder; when rolled in different directions, the carbon nanotubes are arranged in different orientations; when rolled in the same direction, the carbon nanotubes are arranged in a preferred orientation along a fixed direction. . The carbon nanotubes in the carbon nanotube rolled film have a longness of more than 50 μm. [0026] The area and thickness of the carbon nanotube rolled film are not limited and can be selected according to actual needs. The area of the carbon nanotube rolled film is substantially the same as the size of the carbon nanotube array. The thickness of the carbon nanotube film is related to the height of the carbon nanotube array and the pressure of the rolling, and may be 1 micrometer to 1 millimeter. It can be understood that the larger the height of the carbon nanotube array and the lower the pressure applied, the greater the thickness of the prepared carbon nanotube rolled film; on the contrary, the smaller the height of the carbon nanotube array, the more the applied pressure Large, then prepared carbon nanotube rolled film 098143546 Form No. A0101 Page 11 / 28 pages 0982074602-0 201123933 The smaller the thickness. A gap is formed between the adjacent carbon nanotubes in the carbon nanotube rolled film, thereby forming a plurality of micropores 1621 in the carbon nanotube rolled film, and the pore size of the micropores 1621 is less than about 10 μm. [0027] When the carbon nanotubes are arranged in a regular order, the carbon nanotube film can fully utilize the large strength and Young's modulus of the carbon nanotube axial direction in the direction in which the carbon nanotubes are arranged. Therefore, the carbon nanotube film has a large strength and a Young's modulus along the direction in which the carbon nanotubes are arranged. Therefore, according to the position and direction of the centering support piece 160, the position and direction of the Young's modulus can be changed to change the direction of the arrangement of the carbon nanotube film, and the strength and Young's mode of the centering piece 160 in different f directions can be changed. Amount to accommodate the needs of different speakers.
