It is also understood that the number of the first-predetermined milk and pre-pressing units is three or more. The elastic piece 50a has a square flat plate 51 and a lead terminal 53 connected to the square flat plate 51. The lead terminal 53 is used to supply the spring 5 〇a and a power source (not shown) to the coil 40.几何 The geometric center of the plate 51 is provided with a through hole 510 which allows light to pass through the plate 51. The flat plate 51 further has an inner connecting portion 511, an outer fixing portion 512, and four elastic jaws 513. The inner side connecting portion 511 surrounds the through hole 51 and is adjacent to the through hole 51. The outer side solid portion 512 surrounds the through hole 510 and is away from the through hole 51. The four elastic portions 513 surround the through hole 510 and are located between the inner connecting portion 511 and the outer fixing portion 512. * The inner connecting portion 511 is provided with four first positioning units 514 for use with the first positioning post 413, so that the elastic piece 50a is positioned and fixed integrally with the bottom of the movable loading tube 41. In this embodiment, the second positioning unit 514 is not connected to the through hole 51 2010 201042890 ^ through hole ' and the second positioning unit 514 is glued to the first column 4 ΐ 3 glue, of course, the first positioning column 413 can also be used for the ancient chain to save the dispensing process, and the elastic piece 5〇a, k, the positioning column of the head, at this time the body. (4) 5〇a is positioned and fixed to the movable cylinder as - of course, the inner connecting portion 511 is further provided with eight I pre-pressing units 414 to be in contact with the field. The concave portion of the present invention, which is oriented toward the through hole 51 〇 and connected to the 〇 I, is a through hole 151 which is separated from the hole 51_. The first positioning unit 516 is matched with the first positioning unit 324 to cooperate with the first positioning unit 324, so that the fixing portion paste is glued and bonded; The 5Gb conductive terminal 53b is longer than the conductive terminal 53. 〇 It can be understood that the voice coil motor 10 can also have only the elastic piece 5〇a or 50b. Of course, the roles of the two elastic parts 513 can be different. • A square can be used to form a spacer 70 with the outer casing 20. The electromagnetic interference of the isolation box and the prevention of the voice coil of the horse face refer to FIG. 4 'The carrier 60 has a dial with a through hole 6 〇 1 in the center fixed "ϋΪΐ海气面6〇2 and the same The recess 603, which is connected to the hole 〇1, and the four ritual units 324 cooperate with each other. (4) The third positioning unit 604 and the stop unit 6〇5 which are sighed on the surface 6〇2. The notch 603 allows the first positioning post 413 located at the bottom of the movable loading cylinder 41 to pass through the bearing base 60 so as to prevent the carrier 60 from obstructing the movement of the first positioning post 413. The third positioning unit 604 cooperates with the first positioning unit 324 of the fixing frame 32 to fix the seat=integrally with the fixing frame 32. Preferably, in this embodiment, the f-three-bit unit 602 is a positioning groove, and the first positioning unit 324 is received in the first, positioning single towel. Of course, the third positioning unit can also be a stud hole or a positioning post. ▲ The stop unit 605 is used in conjunction with the preload unit 414 to prevent the movable barrel 41 from rotating when the lens barrel is screwed into the movable barrel 41. In this embodiment, the stop unit 605 is a stop block perpendicular to the surface 602, and the height of the block along the central axis of the carrier 60 is smaller than the central axis of the pre-press unit 414 along the movable air cylinder 41. The height is such that the inner connecting portion 511 of the elastic piece 50a of the voice coil motor 10 in the unenergized state is in a different plane from the outer fixing portion 512 thereof, and the elastic piece 5 of the voice coil motor 1 in the unenergized state is directly caused. a has an axial pre-pressure (ie, restoring force) 'the pre-pressure can be balanced with the bearing capacity provided by the carrier 6〇, so that the activity is performed after the voice coil motor W in the unenergized state is axially shaken The initial position of the pocket 41 does not change. When assembled, the two pre-compression units 414 between the two adjacent first positioning posts 413 cooperate with a stop unit 605 such that the stop unit 605 is between the two pre-compression units 414, thereby When the lens barrel is prevented from being screwed into the movable magazine 41, the movable barrel 41 is rotated. Since the stop unit 605 is used in conjunction with the pre-pressing unit 414 to prevent the movable barrel 41 from being rotated when the lens barrel is screwed into the movable barrel 41, the elastic pieces 5〇a and 50b are reduced in sprain. It is possible to reduce the cost of the voice coil motor. Please refer to FIG. 5, which is a movable assembly 40a and a carrier 60a of a voice coil motor (not shown) provided by the second embodiment of the present invention. The movable assembly 4A has a movable cylinder 4ia and a coil 42a wound around the outer wall of the movable cylinder 41a. The movable cylinder 41a is provided with four pre-units 414a near the end surface of the carrier 60a. The surface 6〇2a of the carrier 60a is provided with four stop units 605a. The pre-pressing unit 414a is a pre-pressing column, and the stopping unit 605a sows the groove 'and the depth of the groove is along the central axis of the bearing seat 6〇a is less than 7 201042890. The pre-pressing unit 414a The height of the w-axis of the 4la towel. The IH stop unit 6〇5a is used in conjunction with the preload unit 414a to prevent the movable cylinder from being reversed when the 疋n is turned into a cylinder, thereby preventing the possibility of the bombing. The cost, at the same time, the stop-single 2: Γγ雠 unit 414_ cooperates to prevent the movable cylinder 41 from deviating from its middle when it moves in the direction of the central axis, thereby improving the focusing accuracy of the voice coil motor. Block 60att, the rolling plant unit, he can also be placed in the activity cartridge also close to the bearing 3 concave t, the trough 'At this time, the fresh element 6_ battle column, and the Ο 〇 activity, the depth of the central axis The object of the present invention can also be achieved by the fact that the pre-pressing unit 41 is at the height of the central axis of the moving device. This _2 is only a preferred embodiment of the present invention, and it is not a problem to limit the case. Equivalent modifications or changes made in the spirit of the skill of the case should be covered in the application for patents in the town.
