Description of the Invention: [Technical Field] The present invention relates to a θ ^ miniature microphone, and more particularly to a microspeaker with the following emblem: and the suspension of the π component is integrated \% produces the center of the diaphragm dome to obtain a low regenerative structure, simple structure, reduced grouping procedure, _, ° natural frequency (F0) and wide flat frequency characteristics. [Prior Art] Sounder = even converted to sound signal _. The Yang type speaker is also used to expand the medium and large mp3 for greatly increasing the volume; the small size audio equipment such as mobile phone, notebook, heart ί, 】 earphones, etc. 11. Usually, such a small speaker is hereinafter referred to as a micro speaker 0, and a configuration of a conventional micro-speaker having a general structure will be briefly explained. In the first figure, the conventional microspeaker is exemplified as a schematic diagram. The micro-i speaker 1 is composed of a frame 110, a magnetic pole 2, a permanent magnet 13A, a flat plate 140, a diaphragm 15A, a suspension 160, a voice coil 170, and a cover 180. The frame 110 serves as a member constituting the shape of the microspeaker for mounting other components. The yoke 120, the permanent magnet 130, and the flat plate 140 constitute a magnetic circuit. The diaphragm 150 is divided into an inner portion 152 and an outer portion 154 with reference to the boundary portion 156. The inner and outer sides and the boundary portion of the diaphragm 150 are all formed into a body of 201223298. The inner portion 152 is a partially upwardly convex shape, also referred to as a dome. The outer portion 154 is a portion that surrounds the inner portion 152 from the outer side. As shown, the outer portion 154 is also slightly upwardly convex. The inner and outer portions of the diaphragm differ mainly in the regenerative range, respectively. The outer part is made of a soft material. It is mainly used to reproduce the sound of the low range when vibrating. The inner part is made of a relatively hard material and is mainly used to reproduce the sound of the high range. On the other hand, the outer contour portion of the outer portion 154 is flat, and the outer contour portion is fixed to the frame 110. A cover 180 is incorporated in the upper portion of the frame 110, and other components are built in. Further, below the boundary portion 156 of the outer portion and the inner portion, the sound coil 170 is provided with the suspension 160 interposed therebetween. The upper end portion of the sound coil 170 constituted by the wound wire is adhered to the underside of the suspension 160 disposed below the diaphragm 150. The suspension 160 is disposed to control the movement of the diaphragm 150 in the vertical direction. The function of the suspension 160 is to cause the diaphragm 150 to vibrate only in the up and down direction without moving in the left and right direction. The lower side of the boundary portion 156 of the diaphragm 150 and the suspension 160 are fixed to each other, and the outer rim is also fixed to the frame 110 like a diaphragm. The intermediate portion of the suspension 160 penetrates in the up and down direction. That is, the suspension 160 located below the inner portion 152 of the diaphragm 150 is hollow. A plurality of long, curved grooves are formed in the suspension 160 at a portion below the outer portion 154 of the diaphragm. Such a groove is formed in order to allow the suspension 160 to elastically vibrate in the vertical direction. Adjust the width, length and shape of the groove to adjust the spring force in the downward direction of the suspension in 201223298. On the other hand, although not shown in the drawings, in the case of another conventional micro-speaker, the other configurations are the same as those of the conventional technique shown in Fig. 1, but are used without a suspension. . Further, in the case of another conventional speaker, a diaphragm constructed in such a manner that, in order to better present the treble and the bass, the inner portion and the outer portion of the diaphragm are separated to constitute different members, the members are re They are combined with each other to form a diaphragm. However, in the conventional microspeaker, in the case where the diaphragm is integrally formed, there is a problem in that the elastic force of the outer portion is increased due to the small size of the integral type diaphragm, thereby restricting the reproduction of the low range. That is, due to the limitation of the integrated diaphragm, the high resonance frequency (Fo) and the reproduction range are narrow, and there is a problem that the internal input is low. Further, in order to solve such a problem, although a part of the problem can be solved by forming a diaphragm with a thin material, there is still a problem that the top position of the diaphragm arch of the integrated structure becomes soft together, and the internal input cannot be received. This problem solves some of the problems by adopting a diaphragm formed by forming the inner portion and the outer portion into different members, but this configuration also causes the following problem: when a high input is applied to the speaker, the diaphragm is not a The body shape has abnormal sound and high distortion due to the split vibration and the offset vibration of the diaphragm. Further, when the separator is not formed integrally but is made of a different member, there are the following problems: the number of components is increased, and the number of assembly procedures is increased, so that the production efficiency of the product is deteriorated and the cost is increased. 201223298 SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to manufacture a similar structure by integrating a portion that acts as a dome (inner portion) of a diaphragm onto a suspension. Speakers, but do not increase the number of parts, and have a wide reproduction range, high input speakers with high internal input. The present invention relates to a microspeaker, comprising: a frame; a magnetic circuit portion comprising a magnetic vehicle fixed to the frame, a permanent magnet fixed to the magnetic vehicle, and a flat plate fixed to the permanent magnet; the diaphragm having an edge fixed In the frame, the intermediate portion is formed in a permeable manner; the suspension is located under the diaphragm, the edge of the diaphragm is fixed to the frame, and is formed by a central portion and a peripheral portion formed integrally with each other; the sound coil is fixed to the suspension The lower surface is fixed to the lower portion of the central portion and the peripheral portion of the peripheral portion; and a cover that is coupled to the frame. On the other hand, the center portion of the suspension is preferably formed to protrude upward through the intermediate through portion of the diaphragm. On the other hand, the central portion of the suspension is opposed to the intermediate penetrating portion of the diaphragm, and is preferably convex downward. On the other hand, it is preferable that the center portion of the suspension is provided with at least one ridge formed by a narrow and long shape. On the other hand, there are a plurality of ridges, and the ridges are preferably spaced apart from each other. On the other hand, it is preferable that the peripheral portion of the suspension is provided with at least one portion that penetrates in a shape having a narrow width and a long shape, or at least a portion of which is wrinkled. On the other hand, the suspension is made of polyvinyl chloride (201223298 PV), polyethylene naphthalate (PEN), polyphenylenesulfide (PSS), polyetheretherketone (Polyetheretherketone). ; PEEK), Polyimide (PI), Polyetherimide (PEI), Polycarbonate (PC), and NOM (NOMAX), according to thermoforming The method is preferably manufactured. According to the present invention, it is possible to obtain a microspeaker having a resonant frequency (F〇) having a low regenerability and a wide and flat frequency characteristic by providing a suspension in which the center portion is integrally formed. According to the present invention, it is possible to obtain a high-output speaker having a high internal input by functioning as a diaphragm dome portion by a central portion integrally formed on the suspension. Further, according to the present invention, it is possible to obtain the effect that since the suspension includes the dome portion of the conventional diaphragm and is integrally formed, the number of parts is small, the assembly is simple, and the assembly cost is reduced. On the other hand, when a ridge is provided at the center of the suspension, the effect of sufficiently securing the rigidity of the center portion can be obtained. [Embodiment] A microspeaker according to an embodiment of the present invention will be described in detail below with reference to Figs. 2 to 6 . The microspeaker 1 of the present embodiment includes a frame 1A, a yoke 2A, a permanent magnet 30, a flat plate 40, a diaphragm 50, a suspension 60, a voice coil 7A, and a cover 80. 201223298 This micro speaker 1 is a micro speaker for small audio devices such as mobile phones, headphones, and MP3. The main feature of the present invention is that the suspension 60 is constructed by integrally forming a portion where the diaphragm dome acts, that is, the center portion is integrally formed. The frame 10 is usually made of plastic to form the shape of the speaker and to hold various components inside. The lower portion of the frame is combined with the yoke 20 and sealed. A cover 80 having a plurality of vent holes 82 is joined to the upper end portion of the frame 10. A contour portion which is an edge of the diaphragm 50 and the suspension 60 is fixedly coupled between the upper end portion of the frame 10 and the cover 80. The vent hole 82 of the cover 80 is for arranging the generated audio to the outside. The magnet roller 20 is made of a material having magnetic properties and is fixed to the frame 10.

The diaphragm 50 can be made of a relatively thin material f to create a known diaphragm, domain audio. Reproduction desired sound The diaphragm 50 of the present embodiment is located outside the boundary portion where the upper end portion of the voice coil 7Q is located. _ 5G _ qing, the boundary parts of the inner side and the outer side are flat. As long as the diaphragm has a portion penetrating in the vertical direction in the intermediate portion, the other configuration of the diaphragm, the specific shape, material, and thickness of the diaphragm used in the present invention can be variously changed. The suspension 60 is located below the diaphragm 50. The profile of the suspension 6 is fixed to the frame 10. The suspension 60 is composed of a center portion 62 and a peripheral portion 64. The center portion 62 and the peripheral portion 64 are integrally formed as one member. The intersection portion of the center portion 62 and the peripheral portion 64 is the boundary portion 65. The diaphragm 50 is fixed to the upper side of the boundary portion, and the voice coil 70 is fixed to the lower side. In the case of this embodiment, the suspension is formed of a high molecular material which can be thermoformed, such as polyvinyl chloride (PV), etc. 9 201223298. The suspension 60 can be manufactured by an injection molding method. In the case of other embodiments, the suspension may be fabricated from the following materials: polyethylene naphthalate (PEN), polyphenylene sulfide (PPS), polyetheretherketone (PEEK), Materials that can be produced by thermoforming methods, such as Poly Imide (PI), Polyetherimide (PEI), Polycarbonate (PC), and Nobel (NOMAX). Further, the suspension 60 of the present embodiment is formed such that a portion where the center portion 62 penetrates through the intermediate portion of the diaphragm 50 is convex upward. The central portion 62 has a shape similar to that of the conventional dome portion of the diaphragm. In the case of the present embodiment, the peripheral portion 64 of the suspension 60 is provided with a total of four portions 66 that penetrate in a narrow and long shape. The shape of the through portion 66 is formed symmetrically with respect to the center of the suspension 60. Due to the penetration portion 66, the suspension 60 can be elastically vibrated in the vertical direction. By adjusting the width, length, and shape of the through portion 66, the elastic force of the suspension 60 in the up and down direction can be adjusted. On the other hand, the suspension 60 of the present embodiment is in an upwardly convex form, but the present invention is not limited thereto. That is, in the case of other embodiments, although the center portion of the suspension is not shown in the drawings, it may be formed in a downward convex shape. This case is also the same as the previously proposed embodiment, in which the center portion faces the intermediate penetrating portion of the diaphragm and is located below the through portion. In the case of this embodiment, the electrical connection portion 90 is provided on one side of the frame 10. An acoustic coil 70 is connected to the electrical connection portion 90, so that an electrical signal of the external electrical device is applied to the acoustic coil 70. Hereinafter, the action and effect of the microspeaker 1 having this configuration will be described. 201223298 External system=The micro-speaker 1 of the embodiment has the following advantages: the diaphragm only has a shape in which the intermediate portion is penetrated in the up-and-down direction, and the diaphragm m-protrusion is formed on the suspension, so that the diaphragm can be formed on the suspension. >, wide and wide frequency characteristics. That is, the center of the suspension is mainly responsible for regenerating the high-range audio, and the negative negative bass audio of the diaphragm, which makes up for the shortcomings of the audio in the middle of the vault and the surrounding ribs and the formation of P, which is unable to reproduce sufficient sound range. The known speaker can have a wide frequency characteristic compared to '. Further, since the center portion is formed into a body, the following advantages are obtained: The number of four pieces does not increase as compared with the conventional one, and therefore the manufacturing cost does not increase due to the increase in components and programs. In addition, there is an advantage that according to the present embodiment, a micro speaker having a resonance frequency (Fo) having a low regenerability and a wide flat frequency characteristic can be obtained. Further, there is an advantage that according to the present invention, the center portion integrally formed on the suspension functions as a dome portion of the diaphragm, so that a high-output speaker having a high internal input can be manufactured. On the other hand, the plan view of the deformed suspension 6A in Fig. 7 is shown in Fig. 8 as a cross-sectional view taken along line 7 of Fig. 7. The center portion 62a of the suspension 60a is provided with a ridge 63a which is formed to protrude upward in a narrow and long shape. On the other hand, in the case of other embodiments, the ridges 63a may also be formed to protrude downward. A total of four ridges 63a' are provided at a distance from each other and arranged side by side. Through the configuration of such a ridge 63a, it is possible to obtain the effect of the 201223298 which is more rigid in the center portion 62a. On the other hand, in the case of other embodiments, the specific shape and number of the ridges can be variously modified. 〃 - - 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The center portions 62A and 62c of the suspensions 6〇b and 6〇c are identical to the center portion 62 of the suspension 60 of the first embodiment, but the configuration of the peripheral portions 64b and 64c is deformed. That is, in the case of the ninth figure, the wrinkle portion which is folded into a zigzag shape is repeatedly formed in the peripheral portion 6 repeatedly. In the case of the first drawing, the wrinkle portion is formed integrally on the peripheral portion 64c. In the case of the peripheral portions 64b, 64c of the suspensions 6〇b, 6〇c of the ninth and first embodiment, the specific shape of the pleated portion can be variously modified, and the desired deformation can be obtained. elastic force. On the other hand, the micro-speakers of the above-mentioned embodiments are generally in the form of a circular shape, and the internal configuration thereof is also circular, but may be formed into an elliptical shape, a quadrangular shape or a runway like a sports field according to an embodiment. form.
