INSTRUCTIONS: [Technical field to which the invention pertains] In particular, the invention relates to a sounding device for a carbon tube of a sounding device. [Prior Art] The sounding device is generally composed of a signal age person, a class j π# transmission device, and a sounding element. The electric signal is input through the No. 4 input device, and the sound is generated by the electric signal, electric, irrigation, and sound. First ❹ ❹ : The sounding component in operation is generally a speaker. The speaker is an electroacoustic device that converts the sound into a sound signal. Specifically, the speaker can convert the 曰 frequency electric power signal in the range of 疋 to a audible sound with a small distortion and sufficient sound pressure level. There are many types of speakers, which are divided into: electric speakers, electromagnetic speakers, electrostatic speakers and electric speakers. Although: their J1 is made in a different way, it is a kind of “electric-force-acoustic” conversion by generating mechanical vibration to push the surrounding air and causing the air medium to fluctuate. Among them, electric speakers are the most widely used. Referring to Fig. 1, the prior electric speaker 100 is generally composed of three parts: a voice coil 102, a magnet 1〇4, and a diaphragm 1〇6. The voice coil 1〇2 usually uses a current-carrying conductor. When an audio current signal is input to the voice coil 1 〇2, the voice coil 102 corresponds to a current-carrying conductor. Since the magnet 1〇4 is placed in the morning, the principle of the motion of the current-carrying conductor in the magnetic field will be subject to the principle that the voice coil 102 will be proportional to the audio current and the direction will vary with the audio current. And the power of change. Therefore, the voice coil 1〇2 generates vibration under the action of the magnetic field generated by the magnet 104, and drives the diaphragm 1〇6 200950569. Vibration, the air before and after the diaphragm 106 also vibrates, and the electrical signal is converted into, The sound waves radiate around. However, the structure of the electrodynamic speaker 1 (9) is complicated, and it must operate under magnetic conditions. Since the early 1990s, nanomaterials represented by nano-carboniferous tubes (see nncrotubules of graphitic carbon, Nature, Sumio Iijima, v〇1 354, p56 (1991)) have their unique structure and Nature ^ people have great concern. In recent years, with the carbon nanotubes and nano-nano, the continuous application of Yanjiu's continuous ice has been revealed. For example, due to the unique electromagnetic, optical, and force winds of the carbon nanotubes, there is a large amount of research on the fields of electrons, sensors, new materials, soft ferromagnetic materials, etc. It has been reported 1 and the carbon nanotubes have not been found in the prior art for acoustics. In view of the fact that this type of structure is simple, it can be used in a non-magnetic sounding device. SUMMARY OF THE INVENTION A sounding device includes a signal input device and a sounding element, wherein the sounding element includes a carbon nanotube junction device input signal to the carbon nanotube 31 ί5 (4) hot ambient gas The medium emits sound waves. Compared with the prior art, the sounding device has the following advantages: the sounding component in the device only includes the carbon nanotube structure, and the no-input signal causes the temperature of the nanotube structure to be utilized. The input is not branched so that the surrounding gas is 8 200950569. In turn, the sound wave is emitted, so the carbon nanotube structure is composed, and the '" can work under non-magnetic conditions. Thirdly, due to the small heat capacity and large specific surface area of nano magnetic and ΐ::!, the carbon nanotubes, rice, carbon tube: catch, heat lag is small, heat exchange speed is fast, so The nanophone, and the sounding device can emit a sound dioxin effect in a wide spectrum range. Fourth, when the carbon nanotube structure is thick, for example, less than 10 micrometers, the carbon nanotube structure For the sake of transparency, the sounding device constructed by the text is (4) Anming sounding device. Its five, _ two-sided strong production and carbon tube structure have good mechanical strength and toughness, 'durability is good, and the various shapes and sizes of the structure are composed. Sounding ^Unfilled carbon pipe joints in various fields. Ding's hairpin device, and then conveniently applied to the [embodiment]. The vocal-mounted electrode 142 of the embodiment of the present technical solution will be described in detail below with reference to the accompanying drawings. The pole (4) and the second electrode 144 are spaced apart from each other, and the first electrode 121 is electrically connected to the k-type input device. The first electrode 142 and 14 are firstly connected. The electrode 144 can serve to support electricity. In addition, the first electrode 142 And the second electrode 144 is connected to the two ends of the input device 12 by the external wire 149. The first embodiment of the present invention provides a sounding device 14, 2, 10 including a signal input device. 12, a sound element 9 200950569 is electrically connected for inputting a signal in the signal input device 12 into the sound emitting element 14. " The sounding element is small, 丨, π e and secluded. The crucible is layered or otherwise shaped and has a large specific surface area. The carbon nanotube structure includes uniformly distributed carbon nanotubes, and the carbon nanotubes are tightly bonded by van der Waals force. The carbon nanotubes in the carbon nanotube structure are disordered or ordered. Specifically, when the carbon nanotube structure includes a disordered arrangement: the carbon nanotubes are intertwined or isotropically arranged: Too much: When the carbon tube structure includes ordered carbon nanotubes, the carbon nanotubes are arranged along the 0 to 5 or the most preferred orientation. The thickness of the carbon nanotube structure is the area of the nanocarbon. The thickness of the tube structure is too large, then the ratio; the carbon nanotube structure The thickness is too small, then:: ί 〇 〇 too: the use is not good enough. Preferably, the structure of the carbon nanotubes is as small as two:;;:! The thickness of the carbon nanotube structure is relatively small, the case is not, The carbon nanotube structure is transparent: the sounding device of the tube structure is a transparent sounding device, and the display device such as the display crying can be kindly displayed. The direct women's clothing is in each sounding device, and the surface is used as a space-saving transparent Lu double-walled carbon nanotube. And the wall of the multi-walled wall is not the diameter of the carbon-carbon tube is Μ nanometer ~ 50 nm 'the double-walled nano μ & 1 ', ', · not meters ~ 50 nm, the multi-wall too half The basic answer is that the ancient 仏 is 1.5 nm ~ 5 〇 k k 2 2 is not uncarbonized, the specific structure is not limited, the mouth, the solution, the shape of the carbon nanotube structure, and has two conditions, namely: It is a layered or large specific surface area; it includes a nano-carbonized carbon 200950569 tube with a uniform hook distribution, and a thickness of 〇·5 nm to 丨 mm. In the embodiment of the technical solution, the non-minol tube structure comprises an ordered arrangement of carbon nanotubes, and the carbon nanotubes are arranged in a preferred orientation along the .-solid direction. The carbon nanotube structure has a thickness of nanometer. The first electrode 142 and the second electrode 144 are formed of a conductive material, and the specific shape structure thereof is not limited. Specifically, the first electrode 142 and the second electrode 144 may be selected in the form of a layer, a rod, a block, or the like. The material of the first electrode 142 and the second electrode 144 may be selected from a metal, a conductive paste, a carbon nanotube, an indium tin oxide, or the like. In the embodiment of the present invention, the first electrode 142 and the second electrode 144 are rod-shaped metal electrodes. Both ends of the sound emitting element 14 are electrically connected to the first electrode 142 and the second electrode = 4, respectively, and are fixed by the first electrode 142 and the second electrode 144. Since the first electrode 142 and the second electrode 144 are spaced apart, the sounding element can be applied to the sounding device 1 能 to access a certain resistance value to avoid short circuit phenomenon. Since the carbon nanotube has a large specific surface area under the action of © Van der Waals force, the carbon nanotube structure itself has good adhesion, so when the carbon nanotube structure is used as the sounding element 14, the The first electrode 142 and the second electrode 144 and the sound emitting element "can be directly adhered and fixed" and form a good electrical contact. - In addition, the first electrode 142 is oscillating the second electrode 144 and the sounding element Further, a conductive dot layer (not shown) may be further included between the U. The conductive bonding layer may be disposed on the surface of the sound emitting element 14. The conductive bonding layer implements the first electrode 142 and the second electrode 144. The first electrode 142 and the second electric 200950569-pole 144 can be better fixed to the sound-emitting element 14 while being in electrical contact with the sound-emitting element 14. In this embodiment, the conductive bonding layer is The signal input device 12 includes an audio signal input device, an optical signal input device, an electrical signal input device, an electromagnetic wave signal input device, etc. Accordingly, the signal input by the signal input device 12 is not limited. Including electromagnetic waves, alternating current signals, audio signals, optical signals, etc. It can be understood that the signal input by the signal input device U is related to the specific application of the sounding device 1〇, for example, when the sounding device 1〇 is applied. In the case of the radio, the signal input by the signal input device 12 is an electromagnetic wave; when the sounding device 1 is applied to the earphone, the signal input by the signal input device 12 is an alternating current signal or an audio electrical signal. The signal input device is an electrical signal input device. It can be understood that, according to the signal input device 12, the first electrode 142 and the second electrode 144 are optional structures, such as when the input signal is light or electromagnetic waves. In the case of a signal, the signal input device 12 can directly input a signal signal to the sound emitting element 14 'without electrodes and wires. The sounding device 1 is used, because the carbon nanotube structure is uniformly distributed by the carbon nanotubes. Composition, and the carbon nanotube structure is layered, has a large specific surface area, and has a small thickness, so the carbon nanotube structure has a small hot valley And a large heat-dissipating surface, after inputting the signal, the carbon nanotube structure can rapidly rise and fall aa, generate periodic temperature changes, and quickly exchange heat with the surrounding gas medium, so that the surrounding gas medium rapidly expands and contracts, and then makes a sound. Therefore, in the embodiment of the technical solution, when the input signal is an electrical signal, the sounding principle of the sounding element 14 is ''electric_hot_sound,' conversion; when the input 12200950569 input signal is an optical signal, The principle of sounding of the sounding element 14 is "light· ♦ heat-to-sound conversion. The sounding device 1 composed of the above-described sound emitting element 14 has a wide range of applications. The sounding device 10 provided by the embodiment of the present technical solution can achieve a sound intensity of 100 dB, and the sounding frequency ranges from iHz to ^10,000 (i.e., ΙΗζ-lOO kHz). Item 3 is a frequency response characteristic curve of the sounding device 1〇 when a carbon nanotube film having a length and a width of 3 〇 and a carbon nanotube tube arranged in the same direction as the sounding element 用作14 is used. . As can be seen from FIG. 3, the sounding device 1 has a good sounding effect. In addition, the carbon nanotube structure in the embodiment of the technical solution has a good edge and mechanical strength. The carbon tube structure can be conveniently made into various shapes and sizes of the sound emitting device 1G, and the sound generating device 1G can be conveniently applied to various electronic fields such as audio, mobile phones, Mp3, deletion, television meters, and the like. The sounding device is in the middle of the sounding device.

The hair 13 200950569 = member 24 is disposed around the first electrode 242, the second electrode (10), the third electrode ♦ ^46 and the fourth electrode (10) and is associated with the first electrode (10), Second, ^44, the third electrode (10) and the fourth electrode (four) are respectively electrically connected, and the H 2 shaped sounding element 24 is 4. The two adjacent electrodes are respectively electrically connected to the two sides of the:: input device 22 Connected so that the poles located between adjacent electrodes are connected to the input signal by using ::24. Specifically, the two electrically-disconnected wires 249 that are not adjacent are first connected and then electrically connected to one end of the signal input device 22. The two electrodes of the arm are electrically connected to the other end of the signal input device 2 by the wire 2 (four). In the embodiment of the present invention, the wire 242 and the third electrode 246 may be used first. After the state is connected, it is electrically connected to the end of the signal input device 22, and then the second electrode (10) and the ::= pole 248 are connected by a wire 249 and then connected to the other of the signal input device 22. The method can realize the parallel connection of the nano carbon between adjacent electrodes. The carbon nanotube structure after parallel connection has a small resistance, ❹ ::: operating voltage. Moreover, the above connection manner can make the sound emitting element 24 have a larger radiation area' and the sound intensity is enhanced; the sound effect. Further, when the area of the sound emitting element 24 is large and the fourth electrode 248 is further advanced, it functions to support the sound generating member 24. It is to be understood that the first electrode 242, the second electrode 244, the third electrode 246, and the third electrode 248 may also be disposed in the same plane as the utterance elements 4. The manner in which the electrodes disposed in the same plane are connected is the same as or similar to the manner in which the electrodes are connected. It can be understood that the present technical solution can provide a plurality of electrodes, the number of which is not limited, and 200950569 only needs to ensure that any two adjacent electrodes are respectively electrically connected to both ends of the signal input device 22.发 Compared with the prior art, the sounding device has the following advantages: First, the sound emitting element of the sounding device towel only includes a carbon nanotube structure, and no other complicated structure such as a magnet is needed, so the structure of the sounding device is better. For the sake of simplicity, there is a reduction in the cost of the sounding device. Secondly, the sounding device uses the input No. 7 to form a Heinemi carbon tube structure temperature change, so that the surrounding gas rapidly expands and contracts, and then emits sound waves, so the (four) carbon tube junction of the sounding device can be Working under magnetic conditions. Third, because the carbon nanotube structure has a small hot valley and a large specific surface area, the carbon nanotube structure has the characteristics of rapid temperature rise, small thermal hysteresis, and fast heat exchange rate. Therefore, the sounding device composed of the carbon nanotube structure can emit sounds within the width of the system (1Ηζ_1_Ηζ), and has a good sounding effect. Fourth, when the thickness of the carbon nanotube structure is relatively small, for example, less than 1 ( Micron, the carbon nanotube structure is transparent. Therefore, the sounding device is a transparent sounding device, and can be directly mounted on various display devices such as a display, an oil painting, etc., that is, a space-saving transparent sounding device. The carbon nanotubes have better mechanical strength and dynamic properties, so the carbon nanotube structure composed of carbon nanotubes has better mechanical strength and toughness, and has better durability, which is beneficial to the structure of the carbon nanotubes. The various shapes and sizes of the hair (four) are conveniently used in various fields. In summary, the invention has indeed met the requirements of the hair-type, and the patent application is filed according to law.
