The carbon nanotube membrane structure has a plurality of micropores. The amorphous carbon structure includes a plurality of amorphous carbon particles filled in the pores of the carbon nanotube membrane structure. [0010] ο Compared with the prior art, the carbon nanotube film structure and the amorphous carbon particles of the vibrating membrane are carbon materials, and the carbon material has a small density, so the carbon nanotube and amorphous The diaphragm made of carbon particles has good high temperature resistance and low quality. At the same time, since the carbon nanotube itself has excellent mechanical properties, the carbon nanotube film structure formed by the plurality of carbon nanotubes also has excellent mechanical properties; and the amorphous carbon particles are dispersed in the carbon nanotube film. The structure t can increase the compactness of the layered carbon nanotube composite structure and the bonding force between the carbon nanotubes, and further increase the specific strength of the layered carbon nanotube composite structure. Therefore, when the diaphragm vibrates, 形[0011] [0012] the deformation, stress and tension formed by the vibration can be completely transmitted or shared to each of the carbon nanotubes and the amorphous, obstructing particles.

Slice 160. The magnetic field system 120, the voice coil 130, the voice coil bobbin 140, the vibrating membrane 150, and the centering support 160 are fixed by the bracket 110. The voice coil 130 is disposed on the outer surface of the voice coil skeleton 140 and is received by the voice coil bobbin 140 in the magnetic 098143547 Form No. A0101 Page 5 / Total 33 page 0982074604-0 201123931 Road system 120. One end of the diaphragm 150 and the centering piece 160 is fixed to the bracket 110, and the other end is fixed to the voice coil bobbin 140. [0013] The bracket 110 is a truncated cone structure with one end open, and has a cavity 111 and a bottom portion 112. The cavity 111 accommodates the diaphragm 150 and the centering piece 160. The bottom portion 11 2 also has a central aperture 113 for nesting the magnetic field system 120. The bracket 110 is relatively fixed to the magnetic field system 120 by the bottom portion 11 2 . [〇〇14] The magnetic field system 120 includes a magnetically permeable lower plate 121, a magnetically permeable upper plate 122, a magnet 123, and a magnetic core post 124. The opposite ends of the magnetic body 123 are respectively arranged by concentricity. The magnetic lower plate 121 and the magnetic conductive upper plate 122 are sandwiched.

The voice coil 130 is received in the magnetic field gap 125, which is a driving unit of the speaker 1 , and the voice coil 130 is formed by winding a thin wire on the voice coil bobbin. Preferably, the wire is Enameled wire. When the voice coil 13〇 receives the 9-frequency signal, the voice coil 130 generates a magnetic field that changes with the audio current, and the interaction between the changed magnetic field and the constant magnetic field in the magnetic field gap 1 2 5 The voice coil 130 generates vibration. 098143547 Form No. 101 0101 Page 6 / Total 33 Page 0982074604-0 201123931 [0016] The voice coil bobbin 140 is a hollow tubular structure that is concentrically disposed with the magnetic core stud 124 and spaced apart from the magnetic core post 1 24 . And partially received in the magnetic field gap 125. The outer surface of the voice coil bobbin 140 is fixed to the voice coil, and is fixed away from the center of the vibrating membrane 15 at one end of the magnetic field system 120.

[0017] The centering piece 160 is a wavy annular structure composed of a plurality of concentric rings. The inner edge of the centering piece 160 is sleeved on the voice coil bobbin 14 , for supporting the voice coil bobbin 140 ′. The outer edge of the centering piece is fixed to the 支架 支架 bracket 110 near one end of the center hole 113 The centering piece has a large radial rigidity and a small axial rigidity, so that the voice coil 13 is freely moved up and down in the magnetic field gap 125 without lateral movement, avoiding the voice coil 130 and the magnetic circuit. System 120 touches. [0018] Please refer to FIG. 3, the diaphragm 150 has a speaker unit 1 and the shape and structure of the diaphragm 150 is not limited, and is related to its lift application, such as when the diaphragm 150 is applied to a large speaker 1 The diaphragm 15 can be a hollow and inverted cone structure; when the diaphragm 15 is applied to the micro diaphragm 150, the diaphragm 150 can be a circular or elliptical sheet structure. .

Structure 152. The carbon nanotube film structure 151 includes a plurality of carbon nanotubes 1511. Further, the carbon nanotube film structure 151 includes a plurality of micropores 1512 formed by the plurality of carbon nanotubes 1511. Specifically, the adjacent carbon nanotubes 1511 are combined by van der Waals force to form the self-supporting carbon nanotube film structure. The plurality of amorphous carbon particles 1521 (Amorphous carbon) are combined by a covalent bond to form an amorphous carbon structure 152. [0020] The so-called "self-supporting structure", that is, the carbon nanotube film structure 151 can maintain its own specific shape without being supported by a support. Since the large number of carbon nanotubes 511 in the self-supporting carbon nanotube film structure 151 are attracted to each other by the van der Waals force, the carbon nanotube film structure 151 has a specific shape to form a self-supporting structure. The carbon nanotube film structure 151 may be a film-like structure formed of at least one carbon nanotube film. When the carbon nanotube film structure 151 includes a plurality of carbon nanotube films, the plurality of carbon nanotube films are laminated.

Carbon tube film. Each nano carbon tube film comprises a plurality of carbon nanotubes 1511 which are substantially parallel and parallel to the surface of the carbon nanotube film. Specifically, the plurality of carbon nanotubes are arranged end to end by van der Waals force and are arranged in a preferred orientation in substantially the same direction. The preferred orientation means that most of the carbon nanotubes in the carbon nanotube film have a larger 098143547 in a certain direction. Form No. A0101 Page 8 / Total 33 Page 0982074604-0 201123931 Orientation probability, preferred orientation can also be understood as the majority The axial directions of the carbon nanotubes extend substantially in the same direction. It can be understood that since the large number of carbon nanotubes 1511 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, the carbon nanotube film is made specific. The shape forms a self-supporting structure. The carbon nanotube segments have any width, thickness, uniformity, and shape. The thickness of the carbon nanotube film is from 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. [0022] When the carbon nanotube film structure 151 comprises a laminated multilayer carbon nanotube film, a preferred orientation alignment of the carbon nanotubes 1511 in the adjacent two layers of carbon nanotube film is formed. A crossing angle α, 〇: greater than or equal to 0 degrees and less than or equal to 90 degrees. There is a gap between the adjacent carbon nanotube film or between adjacent carbon nanotubes 1511 in a carbon nanotube film, thereby forming a plurality of micropores 1512 in the carbon nanotube film structure 151. The pores 1512 have a pore size of less than about 10 microns. [0023] The carbon nanotube membrane structure 151 can be a carbon nanotube flocculation membrane, which is obtained by flocculation of a carbon nanotube raw material to obtain a self-supporting nanometer. Carbon tube membrane. The carbon nanotube flocculation membrane comprises carbon nanotubes which are intertwined and uniformly distributed.

Carbon tube membrane. The carbon nanotube rolled film comprises a uniformly distributed carbon nanotube 1511, and the carbon nanotubes 1511 are arranged in the same direction or in different directions. The carbon nanotubes in the carbon nanotube rolled film are partially overlapped with each other and are attracted to each other by the van der Waals force, so that the carbon nanotube film structure 151 has a good slick property. Fold into any shape without breaking. Moreover, since the carbon nanotubes 1511 in the carbon nanotube rolled film are closely attracted to each other by the van der Waals force, the carbon nanotube (four) film is a self-supporting structure. The carbon nanotubes in the film block form an angle with the surface of the carbon nanotube-shaped growth substrate to form an angle of /3 'the tenth of which is greater than or equal to the degree of twist and less than or equal to ^ degrees. The force on the carbon nanotube array is related to the force. The larger the movement, the smaller the angle. Preferably, the carbon nanotube (098) in the carbon nanotube (four) film is 098143547.

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 1 511 can be arranged in disorder; when the pressure is blocked in different directions, the carbon nanotubes 1511 are preferentially oriented in different directions; when the pressure is blocked in the same direction, the nanotubes 1511 are in a fixed direction. Preferred orientation. The carbon nanotube rolled film allows the length of the carbon nanotube 1511 to be greater than 5 μm. [0025] The area and thickness of the carbon nanotube rolled film are not limited, and may 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 from 丨 micrometer to 丨 millimeter. It can be understood that the height of the carbon nanotube array is larger and the wish is applied. The smaller the force, the larger the thickness of the prepared carbon nanotube rolled film; on the contrary, the smaller the height of the carbon nanotube array is, the applied pressure The larger the diameter, the smaller the thickness of the prepared carbon nanotube rolled film. There is a certain gap between the adjacent carbon nanotubes 1511 in the nano-carbon nanotubes, so that a plurality of micropores 1δ12 and micropores 丨5丨2 are formed in the Nailong tube rolling film. It is less than about 1 micron. When the carbon nanotubes 1511 are arranged in a regular order, in the direction in which the carbon nanotubes are arranged, the carbon nanotube film can fully utilize the large strength and Young's modulus of the carbon nanotubes in the axial direction, thereby The carbon nanotube film has a large strength and a Young's modulus along the axial direction of the carbon nanotube 1511 therein. Therefore, the intensity and Young's modulus of the vibrating membrane 15 can be changed according to the position and direction of the vibrating membrane 150 to increase the strength and the Young's modulus by changing the direction in which the carbon nanotube film is disposed.

Further, the plurality of amorphous carbon particles 1521 are attached to the wall of the carbon nanotube 1511 or coated on a part of the surface of the carbon nanotube. In the present embodiment, the amorphous carbon structure 152 further includes a plurality of amorphous carbon particles 1521 disposed on both sides of the carbon nanotube film structure 151 to form two amorphous carbon layers. That is, the carbon nanotube film structure 151 is completely coated by the amorphous carbon structure 152 and is composited inside the amorphous carbon structure 152.

Specifically, the covalent bond includes a sp2 or sp3 bond formed between carbon-carbon atoms. Therefore, from the macroscopic view, the amorphous carbon structure 152 has a sponge-like structure, and the carbon nanotube film structure 151 is buried therein. In other words, the plurality of carbon nanotubes 1511 are disposed in the amorphous carbon structure 152 in the form of a self-supporting carbon nanotube film structure 151, and the amorphous carbon structure 152 and the plurality of carbon nanotubes pass through the van der Waals Valli and covalent bonds are combined.

Irregular. The amorphous carbon particles 1521 include bone charcoal, carbon black, and the like. The amorphous carbon particles 1521 can be obtained by low-temperature carbonization of a polymer material such as polyacrylonitrile fiber, pitch fiber, viscose or phenolic fiber. In the present embodiment 098143547 Form No. A0101 Page 12 of 33 0982074604-0 201123931 Ο The amorphous carbon particles 1 5 21 are prepared by carbonizing the polyacrylonitrile fiber around 100 Å. Further, the method for preparing the layered carbon nanotube composite structure comprises the following steps: First, a polymer material is formulated into a solution and infiltrated into the carbon nanotube film structure 151, the polymer material and the nanometer The carbon nanotube 1511 in the carbon tube membrane structure 151 can be bonded by a covalent bond and a van der Waals force. Next, the carbon nanotube treatment impregnates the carbon nanotube membrane structure 151 of the polymer material solution, so that the polymer material loses part of nitrogen, hydrogen, and oxygen to form an amorphous carbon structure 1 52, and the carbon nanotube membrane structure 151 Embedded in it. The amorphous carbon structure 152 is a unitary structure, and a part of the amorphous carbon particles 1521 in the amorphous carbon structure 152 is filled in the carbon nanotube film structure 151; a part of the amorphous carbon particles 1521 is disposed on the carbon nanotube film structure. 151 sides. [0030] The vibrating membrane comprises a carbon nanotube membrane structure formed of a plurality of carbon nanotubes and a plurality of amorphous carbon particles dispersed in the carbon nanotube membrane structure. The carbon nanotubes and the amorphous carbon particles have a small density, so that the diaphragm made of the carbon nanotubes and the amorphous carbon particles has a smaller mass. At the same time, since the carbon nanotube itself has excellent mechanical properties, the carbon nanotube film structure formed by the plurality of carbon nanotubes also has excellent mechanical properties; and the amorphous carbon particles are dispersed in the carbon nanotube film. In the structure, the compactness of the layered carbon nanotube composite structure and the bonding force between the carbon nanotubes can be increased, and the specific strength of the layered carbon nanotube composite structure is further increased. Therefore, when the diaphragm vibrates, the deformation, stress and tension formed by the vibration can be completely transmitted or shared to each of the carbon nanotubes and the amorphous carbon particles, so that the diaphragm has a good specific strength. Further, the carbon nanotubes and the amorphous carbon particles are all carbon materials, so the vibration 098143547 Form No. 1010101 Page 13 of 33 0982074604-0 201123931 The film has the advantages of corrosion resistance and moisture resistance.

The method of weaving is not limited, for example, the nanometer carbon line-like structure can be divided into two rows of nano-line-like structures, and a column of nano-carbon line-like structure. The structure is woven with the nano carbon line structure; please refer to step 7, or the trunk structure after the complex nanometer can be divided into a circular nano-shirt line corresponding to the arc of the annular structure of the centering piece. The radial nanocarbon line-like structure directly corresponding to the arc is further woven with the annular nanocarbon line structure and the nanocarbon line structure. The nanocarbon line-like rise single carbon carbon line may also be a strand formed by a plurality of nano carbon lines. The plurality of nano-bundles, or mutually twisted, are arranged in parallel to form a non-twisted nanocarbon pipeline twist line structure. The nano carbon line X button is turned into a nano carbon line. The non-twisted nanocarbon line is obtained for processing. The non-twisted = m " tube pulled through the organic solvent line length direction of the nano carbon camp = line includes a plurality of carbon nanotubes along the carbon nanotube line including a plurality of carbon nanotubes through the body, the f twisted nano Nano carbon pipeline axial preferred orientation demolition ^ Deval force is connected end to end and along the sound = with 〆 m by the side carbon nanotube segments have any length, thickness, uniformity, length and length of the line is not limited, the diameter is 〇.5 ^1. The non-twisted carbon nanotubes are not 400 microns. The twisted nanocarbon line is obtained by twisting (four) in opposite directions. 2 mechanical force (four) nano carbon tube film several round nano carbon line axial spiral row 3 turn nano carbon pipeline including complex twisted nano carbon pipeline including plural ": carbon nanotubes. Specifically, the tail is connected and along the axial direction of the nanocarbon pipeline = the tube passes through the van der Waals force fragment to have an arbitrary length and thickness: the carbon nanotube uniformity and shape. 5纳米至100微米。 The twisted form number is Α0101. Since the nano carbon line is obtained by treating the above carbon nanotube film with an organic solvent or mechanical force, the carbon nanotube film is a self-supporting structure, so the nano carbon official line is a self-supporting structure. In addition, the nanocarbon pipeline has a gap between adjacent carbon nanotubes, so the nanocarbon pipeline has a large number of micropores, and the pore diameter of the micropores is less than about 10 μm. With respect to the speaker 100 in the first embodiment, the speaker 200' of the present embodiment has a carbon nanotube film structure in the diaphragm 250 formed of a plurality of carbon nanowire structures. Since the carbon nanotubes in the carbon nanowire structure are arranged substantially parallel or spirally along the length direction of the nanocarbon line, the carbon nanotube linear structure has a large strength and a Young's modulus in the longitudinal direction. The strength and Young's modulus in this direction can be increased by designing the orientation of the nanocarbon line-like structure. Referring to Fig. 8, a method for preparing a vibrating membrane according to a first embodiment of the present invention includes the following steps. Step S1G1: providing a self-supporting carbon nanotube membrane structure and a polymer, the nanocarbon membrane membrane structure having a plurality of micropores. The carbon nanotube membrane structure comprises a plurality of nano-tubes, and adjacent carbon nanotubes are combined by van der Waals to form a plurality of micropores. The polymer comprises a combination of several of the polyacrylonitrile, asphalt, viscose and mysterious fibers. In this embodiment, the polymer is polyacrylonitrile. Step S102: dissolving the polymer in a solvent to form a polymer solution. The solvent is volatilized and (iv) the polymer has a solvent having a relatively high ability to dissolve, such as tetrahydrofuran or tetra-carbonized carbon. 098143547 Form No. A0101 Page 16 / Total 33 Page 0982074604-0 201123931 [0041] 004 ❹ Step S1〇3 · Make the polymer solution in the carbon nanotube membrane structure as a self-supporting structure丨二S骐, structure. The nanocarbon nanotube membrane structure can be selected by immersing the carbon nanotube membrane structure in the polymer solution. The polymer =: after the polymer is wetted: a part of the polymer solution will penetrate into the nanopore pores and be in contact with the carbon nanotubes in the structure of the carbon nanotube membrane. . Step SUM: carbonization infiltrated with a polymer solution. (4) The polymer is carbonized to amorphous carbon. The Wei temperature channel structure is below the degree and below the degree of high vacuum. Due to the good heat resistance at room temperature, the carbon nanotube structure has no structure or performance change in the carbon bicarbon tube. The nitrogen, hydrogen and oxygen of the fractions of the ridge polymer material form amorphous carbon. Which 'removed most of the ==:=^_ compound solution forming part == ^ filled in the money hole towel, the body of the whole material and the material of the ship's structure formed part of the 妓-shaped carbon distributed in the carbon nanotube film structure ^ The two surfaces. The striated carbon and the carbon nanotube are sewn through a van der Waals force and a valence bond, and the covalent bond is included in the carbon-carbon pro-sub-arc shape of the SP2 or sp bond. And the plurality of amorphous carbons form an indefinite rhyme structure with a monolithic structure through covalent bonding. Thereby, a layered carbon nanotube composite structure is formed. [0042] The preparation process of the vibrating membrane does not involve a complicated chemical reaction process, and the reaction conditions are relatively mild. Therefore, the preparation method of the vibrating membrane is simple and low in cost. Referring to Figure 9, a second embodiment of the present invention provides a method of preparing a vibrating membrane comprising the following steps. 098143547 Form No. A0101 Page 17 / Total 33 Page 0982074604-0 [0043] Step S201: providing a self-supporting carbon nanotube membrane structure and a polymer 4 monomer, the carbon nanotube membrane structure With a plurality of micropores. The polymer monomer is a compound capable of undergoing polymerization such as a double bond, a hydroxyl group, a carboxyl group or an epoxy group. In this embodiment, the polymer monomer is polypropylene having a double bond. [0045] Step S202: dissolving the polymer monomer in a solvent to form a polymer monomer solution. The solvent is a solvent which is volatile and has a strong dissolving power for the polymer monomer, such as tetrahydrofuran or carbon tetrachloride. [0046] Step S203: the polymer monomer solution is impregnated into the carbon nanotube film structure and the polymer monomer is polymerized, and the polymer monomer is polymerized and reacted to become a polymer. The polymer monomer solution penetrates into the interior of the carbon nanotube membrane structure, and after polymerization, the polymer monomer is polymerized in situ in the solution to form a polymer, wherein the polymer penetrates into the inner structure of the carbon nanotube membrane structure. The polymer formed by in-situ polymerization of the monomer solution is also combined with the carbon nanotube film structure to form a composite structure. In this embodiment, the polymer monomer is polypropylene which is polymerized in situ to form polyacrylonitrile. [0047] Step S204: carbonizing the composite structure of the carbon nanotube film structure and the polymer to carbonize the polymer into amorphous carbon. [0048] Compared with the method for preparing the vibrating membrane provided by the first embodiment, the present embodiment is obtained by infiltrating the polymer monomer into the carbon nanotube membrane structure and in-situ polymerization of the carbon nanotube membrane structure. The polymer is capable of complexing into the carbon nanotube membrane structure. The polymer can be selected to a wider range even if the carbon nanotube film structure is capable of infiltrating a polymer which is poorly soluble in a solvent.
