DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will now be described in detail, and examples of f are illustrated in the accompanying drawings. ',, 粑 - Fig. 1 is a schematic perspective view of a micro gamma according to the present invention - a specific embodiment, and Fig. 2 is the first! Figure diaphragm micro__ _, vertical - surface, and the third picture is the first! A cross-sectional view of the diaphragm. I don't think about the cross-section - the diaphragm 1 is - the type of sound in a small sound device is set to be such as a mobile phone, a notebook computer, a _player = machine, and the like. The separator i is packaged in a plurality of pure polymer compound films stacked on each other. Brick film, and because of the miniature, the eight diaphragms are mainly small in size, the films are different in shape from the right, and are formed of different materials to achieve the desired sound. The ship has 201119417 although the diaphragm can be single-thin. to make. However, in this embodiment, the diaphragm is formed by stacking at least two thin turns to achieve the desired acoustic characteristics. Meanwhile, Fig. 2 is a perspective view of the micro-ball 100 using the diaphragm of the embodiment, which is cut in half. The micro η 八 〇〇 includes a frame 10 一 a magnetic 扼丨 02, a magnet 103, a flat plate 104 and a voice coil 1 〇 5. An outer cover (not shown) is roughly fixed to the upper portion of the frame block 101. In this case, an outer side of the diaphragm 1 of the specific embodiment is fixed to the frame 101. One of the upper ends of the sound coil 105 is fixed to the bottom surface of the joint portion 30 of the diaphragm 1. The diaphragm 1 of the micro-squadron is formed by stacking the first member 1 and the second member of the blood. The first member 10 and the second member 20 are films formed of a polymer compound such as polyethylene and polyurethane. In order to achieve the desired sound characteristics, the first member 10 and the first member 20 are selected from a plurality of films formed of different materials, taking into consideration physical and chemical characteristics such as strength, melting point, and the like. Meanwhile, as shown in Fig. 1, the diaphragm 1 includes a dome portion which is a portion slightly convex at the center and an edge portion surrounding the dome portion. An edge 12 of the edge portion is flat and is fixed to the frame 101 of the micro-remaining eight hundred. A portion of the dome portion joined to the edge portion will be referred to as a joint portion 30. As described above, the upper end of the sound coil 105 (see Fig. 2) is coupled to the bottom surface of the joint portion 30. In this particular embodiment, the first member 10 includes an inner portion corresponding to the dome portion and an outer portion that surrounds the inner portion and corresponds to the edge portion of the 201119417. The size of the second member 20 corresponds to Positioned on the inner side portion. The inner portion of the cow W, therefore, the dome portion has a double-layer structure stacked on the first member member. The edge portion has, two: the member 20 stack and the edge portion design The shape of the dome is different. The sound of the dome is different from that of the second member 2〇, and the program is joined to the corresponding member ig. The ultrasonic wave is connected to the ultrasonic bonding process in a polymer:::=. The bonding process is performed, and the acoustic wave is used to join the human-level program. In general, in the ultrasonic bonding process, the compound in the compound The power becomes 15-2GKHZ f energy, and - the vibration crying device converts 50/60 Ηζ The electric energy becomes mechanical vibration energy. - The work and the booster convert the object to be processed with electric energy. Then, due to the vibration energy of the mechanical device Dissolving the material joint surfaces 2 The generated frictional heat is bonded to the sub-segment. The subdivision between the objects is at the same time as in the specific embodiment, and the second configuration is entirely joined by the ultrasonic joining procedure. The outer peripheral portion is not limited thereto. That is to say, the members are 1 〇. However, the peripheral portions of the outer side of the second member of the present invention are intermittently connected to each other, and the first member can be formed along the same as the second member. The diaphragm ^ can be formed into a rectangular shape, an elliptical shape, or the like, as long as at least two of the polymers in the structure are thin, the ultrasonic bonding process is purely joined. From 201119417, referring to FIG. 3, an air layer 40 is formed at the first The member 10 is interposed between the second member 2A of the dome portion. The air layer 4〇 is mainly filled with air. That is, because the outer peripheral portion of the second member 2〇 is integrally joined to the first member 10', the air is limited. In a space defined by the first member 10 and the second member 20, an air layer 40 is thereby formed. Fig. 4 is a schematic view of one of the diaphragms of the micro-strip sigma according to another embodiment of the present invention. Sectional view. According to another The diaphragm la of the miniature horn of the example includes a first member 10a, a second member 2A, and a third member 22a positioned between the first member 1& and the second member 2A. The three member 22a may be a film formed of a polymer compound or other material. Because the third member 22a is located in a space between the first member i〇a and the second member 2〇a, the third The member 22a may be formed of a material that cannot be applied to the ultrasonic bonding process. When the third member is formed of a polymer compound, an outer peripheral portion of the third member is in the first member and the second member Meanwhile, and they are joined together via the ultrasonic bonding process. Also, although a third member 22a is provided in this embodiment, it is possible to provide two or more third members 22a. According to this embodiment, because the first member and the second member are joined via the ultrasonic bonding process, the joint portion is thick. Therefore, the sound characteristics of these devices are self-contained and some micro defects can be reduced. Furthermore, the engagement of the first and second members can be accurately achieved. 10 201119417 Furthermore, since it is possible to form the air layer between the first member and the second member, it is possible to achieve the desired characteristics of the diaphragm. Furthermore, since at least one additional member is inserted in the air layer, it is possible to adjust the thickness of the diaphragm and the acoustic characteristics of the diaphragm. A method of manufacturing the separator of the microhorn will be described below. The method of manufacturing the diaphragm according to a specific embodiment includes a mold preparation step S1, a first member forming step S2, a second member setting step S3, and an ultrasonic bonding step S4. In the mold preparation step S1, a mold 50 has a shape corresponding to the desired shape of the first member 10. In the first member forming step S2, the first member 10 disposed at the lowermost film of the plurality of films is tied to a forming mold 50 to form the first member 10 of a desired shape. That is, the polymer film is disposed on the mold 50 and formed into a desired shape by another mold (not shown) which can be punched down. In the second member setting step S3, the second member is disposed at a desired position on the first member 10 formed into a desired shape, and thereafter the ultrasonic bonding step S4 is performed. Also in this embodiment, the first member 10 has an inner portion that is a central portion and an outer portion that surrounds the inner portion. The second member 20 is sized to correspond to the inner side of the first member 10 and is positioned on the first member. In the ultrasonic bonding step S4, the first and second members 10 and 20 are joined together at a portion to be joined via the ultrasonic bonding process. Referring to FIG. 5, after the first member 10 is disposed on the mold 50 and the second 11 201119417 member is disposed on the first member 10, the portion 30 to be joined is joined using the tool angle 42 via the ultrasonic bonding program. together. This ultrasonic bonding procedure has been explained above. The method of this embodiment is the method of manufacturing the separator 1 of Fig. 1. Therefore, in the ultrasonic bonding step S4, the outer peripheral portion of the second member 20 is entirely joined to the first member 1''. However, the invention is not limited to this specific embodiment. That is, the second member 20 can be partially joined to the first member. For example, it is possible to intermittently join the second member to the first member along the outer peripheral portion in a circular direction. Further, it is also possible that the engaging portions are spaced apart from each other along the outer peripheral portion, and the individual engaging portions may be disposed in a radial direction. In this case, the configuration of the joints is similar to the configuration of the outer side of the rib. At the same time, =臈7 becomes a variety of shapes' such as a rectangle, a square, an ellipse, and a track shape. In the ultrasonic bonding step S4, the first member 1〇 and the second member form an air layer 4〇 (see Fig. 3). That is, the disk second is joined to the first member 1G only at the joint portion 3G, and the remaining portion members 10 are spaced apart to define the air layer 40. While in this embodiment, the member 10 can be placed on the forming mold 50 by a vacuum suction process. When the first member 1G having the desired shape is disposed on the mold 5, the mold is tightly fixedly contacted by the true two adsorption program. When the first member 10 is tightly fixed to contact the molding mold 5G, it is possible that at 12 50 201119417 > The second member 2〇 is accurately disposed at a desired position on the second member. Moreover, since the position of the first member ίο is not changed in the ultrasonic engagement procedure, the ultrasonic engagement can be accurately achieved at a desired position. Further, since the first member 1G is maintained in the vacuum suction state after the first member 1G is formed by the molding die 5, and in this state, the second member 20 is disposed on the first member 10, the workability can be improved. Meanwhile, in order to manufacture the diaphragm 1a of FIG. 4, the second member setting step S3 further includes a third member setting step for providing at least one third member 22a between the first member 1a and the second 'member 20a. . Referring to Fig. 6, after the third member 22a is disposed between the first member 1& and the second member 20a, the ultrasonic bonding step S4 is performed. The third member 22a has been explained when the diaphragm la is explained above with reference to Fig. 4. According to this embodiment, since the first member and the second member are joined together via the ultrasonic joining process, the thickness deviation at the joint can be minimized. Further, since the first member and the second member are not bonded by the adhesive member, the first member, the second member, and the third member are chemically reacted with the adhesive. Further, since the first member is fixed to the molding die by vacuum suction, the position of the first member can be accurately fixed. Therefore, the first configuration; the joining position to the second member can be accurately controlled, so that the workability can be improved. According to the present invention, the thickness of the joint portion where the films are joined together can be uniform. Also 13 201119417 Furthermore, the joining of the films can be achieved at an exact location, so that the individual films can be formed accurately. Furthermore, since no adhesive is used, defects can be reduced and the yield can be improved. It is also possible to automate production. It will be appreciated by those skilled in the art that various modifications and changes can be made in the present invention. Therefore, it is intended that the present invention cover the modifications and variations of the inventions BRIEF DESCRIPTION OF THE DRAWINGS [0009] The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of the present application, which is a exemplified embodiment of the present invention.
