Description of the new type: [Technical field to which the new type belongs] This creation is about a composition structure of a back pole type capacitor microphone. [Previous technology] According to the current practice, a back-type condenser microphone is generally used in a microphone ', which is formed by the change in capacitance caused by sound waves and converted into an electrical signal. As shown in the first figure, the conventional back pole type capacitor microphone is attached to an aluminum casing 10, and a plurality of sound holes 12 are formed on the front panel 11 of the casing. A diaphragm ring 13 is provided inside the front panel 11 A vibrating membrane 14 is provided on the upper layer of the vibrating membrane ring 13, and the vibrating membrane 14 is in contact with the vibrating membrane ring 13; a gasket 15 is provided on the upper side of the vibrating membrane, and a pole is on the other side of the gasket 15 Plate i 6, the metal is steamed on the surface of the electrode plate to form -polymer_, which is polarized, and the film and the vibrating film 14 form an opposite state, and a plastic cavity 17 is located -The copper ring 18 and the housing i 〇 are used as insulation, and the copper ring 18-end is connected to the electrode plate 16 'and the other end is connected to the wiring substrate 丄 9, and on the back of the copper ring 18 In room 2 0, there is an amplification transformer c element 191, and the-end of the copper ring 18 is connected to! The input terminal 丄 9 2 of the c element i 9 i, and the output terminal χ 9 3 of the IC element 191 is located outside the wiring substrate 丄 9; and the outside side of the wiring substrate i 9 is bent at the end behind the casing i Q, Fix each component. However, the number of parts is relatively high. 'While increasing assembly and assembly time, its manufacturing cost is also M265878 to address the above-mentioned shortcomings.' The f-world has caused Laifa in recent years—a type that can reduce the number of parts. ' A metal cylindrical small box with a sound hole formed on the front panel, and the above-mentioned heteropolymer on the front panel arranged in this small box, and a conductive vibration film disposed near the opposite side of this high position It is composed of a conductive retainer that holds the peripheral edge of the conductive vibration film, and a front electret type backside condenser microphone that seals the wiring substrate on the back of the small box. The design is mainly made of metal. The shell is formed with an electret film on the inner surface of the front panel, which greatly reduces the number of parts. However, after an electret film is formed on the inner surface of the front panel, the film must be peeled off at the rear edge of the shell about 0.8 mm. In order to make the rear end of the casing in an insulated state, if a microphone with a smaller size is to be manufactured, it will cause difficulty in processing and indirectly cause a relatively high manufacturing cost. In view of this, there is a need to improve a back-type capacitor microphone that solves the above problems and achieves both low manufacturing cost and low assembly cost. [New content] The main purpose of this creation is to provide an assembly structure of a back-end capacitor microphone. Through the improvement of the assembly structure, a metal-made tube-shaped casing is formed; several sounds are formed on the front panel. The front panel is provided with an electrode plate, and the surface of the above electrode plate is provided with a polymer miscellaneous plate, and a # 穿 航 卜 振 _ is provided, which is a slightly larger area of the conductive vibration film. A __ skirt is formed on the outside, which can be insulated from the shell; a diaphragm is provided between the diaphragm and the plate to form a state close to the opposite side; a ring of diaphragm, made of metal, is connected to the electrical institute , Located on the side of the diaphragm;-wiring board, M265878 ° zoomed again! c component, the input terminal of the wiring substrate is also connected to the diaphragm ring ^ The output terminal is led out of the wiring substrate and connected to its wiring; the moon surface of the wiring substrate is also external ^: the rear end is folded When assembling, the polar plate, the diaphragm, the diaphragm, the diaphragm ring, and the wiring substrate are placed in order, and then the rear end of the shell is bent to secure the body, thereby reducing the assembly structure. Under the double consideration of the number of parts and then reducing the cost of manufacturing, the ease of self-assembly is improved. In the manufacture of parts, the manufacturing cost and manufacturing technology of simple parts, especially in the era of advanced information, are both small and compact. Low cost must be the winner in the competition of manufacturers. [Embodiment] This creation is based on the i-back-capacitor microphone, as shown in the third figure. This back-capacitor microphone mainly includes a casing i 0, which is made of metal. The cylindrical shape, the front panel of the shell! !! There are several sound holes i 2 for the sound waves to penetrate easily. · -Electrode plate i 6, a polymer film is plated on one surface of the electrode plate i 6, and this polymer film is _ polarized On the board and pass through the track i 6 i for sound waves to pass through the sound hole! 2 When it passes in, it can reach the vibrating membrane 丄 4 through the penetrating hole χ 6 丄, and its vibrating membrane 14 is-a conductive vibrating membrane 'steamed on one side of the film (N soil), Shaoyu, etc. to form -A conductive layer; provided between the vibrating thin i 4 and the electrode plate i 6-a gasket 丄 5 to form a close-to-op state;-the vibrating membranes 3, and the vibrating vibrations 4 are made of metal, At the same time, they are electrically connected to each other, and the diaphragm 4 is slightly larger than the diaphragm ring 13. When placed in the casing 10, a skirt Λ skirt # 141 can be formed and insulated from the casing 丄. The f-chamber 2 Q composed of the vibrating ring 13 and the vibrating surface 14 can accommodate the ic element 191; a wiring substrate 19 is provided with a magnification transformation c element 1 9 1 M265878, the input of the c element 191 The terminal 19 2 is also connected to the diaphragm ring 13, and the output terminal 19 3 is led out of the wiring substrate 19 and is connected to its wiring. The rear surface of the wiring substrate 19 is also fixed by being bent and fixed at the rear end 10x. When assembling, the electrode plate 16, the gasket 15, the vibration film 14, and the vibration ring 13 are inserted into the wire substrate 9 in order. Put 10 towels on the outer shell, and then bend and press the end of the outer shell to make the whole fixed. Compared with the conventional back-type condenser microphone, this creation can reduce the number of parts during the automatic production assembly, and compared with the accessory-, it is easier and easier to manufacture the parts, which can reduce the manufacturing production. The cost, in particular, reduces the polymer film covered on the outer shell, and adds _ part of the polymer _ plus _ scale, which greatly reduces the cost of component manufacturing. From the above, only the preferred embodiment of the creation is explained by Moe. Lin intends to make any form of the creation based on it. Therefore, any modification or creation of the creation in the spirit of _ Changes should still be included in the mouth of the fan intended to be protected in this creation. Among them, the diaphragm ring is not limited to metal materials, and the necessary shape is made of insulating materials. Yes. In summary, 'the back-type capacitor microphone of this creation is indeed in full conformity with the needs of industrial development in terms of structural design, practicality and cost-effectiveness, and the result disclosed ^ creation is also unprecedented innovation Structure, so it has "new nature", and this creation can be more complex than | domain structure, so it is also "progressive," in line with China's patent law requirements for new patent application requirements, A patent application has been filed in accordance with the law, and I invite you to examine it early and give your approval. 9 M265878 m
