In this embodiment, the second magnetic plate is the same composite magnetic polymer as the first magnetic plate 11, i.e., is also a mixed-recorded ferrite (mSr0.nFe203) permanent magnet material in polyamine. The second magnetic plate 14 includes a plate body 140, a plurality of conductive protrusions 141, and a plurality of pressing protrusions 142. In the embodiment, the plate body 14〇, the plurality of conductive protrusions 141, and the plurality of pressing protrusions 142 are integrally formed. . [0015] The shape of the plate body 140 corresponds to the shape of the first magnetic plate ,, and is also a rectangular parallelepiped plate body. The plate body 14 has an opposite first surface 143 and a second surface 144. The first surface 143 is adjacent to the partition plate 13 and is in contact with the partition plate 13. The second surface 144 is away from the partition plate. 13. Near the first surface 143 is an 8 pole of the second magnetic plate 14, 099142908 Form No. AD101 Page 8 / Total 22 Page 0992074387-0 201225127 Close to the second surface 144 is the bungee of the second magnetic plate 14 . Of course, the magnetic poles of the first and second magnetic plates 11 are distributed in a manner of 2', and only the magnetic force of the repelling magnetic field 11 and the second rectification can be generated. 4 [0016] 复 The plurality of conductive protrusions 141 extend from the first surface of the board body 14 and correspond to the plurality of button contacts 127-. Each 143 of 143 extensions are called "the opposite of the trajectory 127 of the red rail 丨 convex exposed to the through hole m towel. Each of the teachings and the 141 is used to contact the contact opening ΐ4ι with the contact opening m under the action of an external force, and electrically connect the first contact and the second contact. The conductive protrusion 141 is rounded and has a diameter smaller than that of the through hole 132 of the 271, so as to be received in the through hole μ and the protruding protrusion m protrudes from the height of the first surface 143. The material is microscopic and leads to 1 micron. Each of the conductive protrusions 141 has a conductive layer 4 formed on the conduction end surface 145 away from the plate Zhaoguang to the conductive end surface 145. The conductive layer 146 may be a conductive carbon paste. . ο [0017] The end face 145 is turned on. The conductive layer 146 has a thickness of 1 μm as described. It is understood that if the second magnetic plate 14 is mixed with a conductive material such as a metal permanent magnet material, the second magnetic plate 4 is provided with conductivity & It is not necessary to form the conductive layer 146. [0018] The plurality of pressing protrusions 142 are located on the second surface 144 of the plate body 14 and correspond to the plurality of points 127. The plurality of pressing protrusions 142 protrude from the first surface 144 away from the first surface m3 for marking. In this embodiment, each pressing protrusion 099142908 form number A0101 page 9/22 page 0992074387-0 201225127 142 is a truncated cone structure. The pressing protrusion 142 protrudes from the second surface 144 to a degree of 5 〇 micrometers to 1 〇〇 micrometer. It is also possible to form numerals, letters, and the like on the plurality of pressing projections 42 by printing or the like. Of course, the second magnetic plate 14 may not have a plurality of pressing protrusions 142, and directly form a number, a letter, and the like at the corresponding position of the second surface 144 and the plurality of button contacts 127, directly on the second surface 144 and the The input can be realized by pressing the corresponding button contact 127 at the corresponding position. [0020] Since the first magnetic plate 14 is S pole near the first surface 143, the first magnetic plate Π is also adjacent to the second magnetic surface 1 η of the second magnetic plate 14 as an s pole, the first magnetic The plate 11 and the second magnetic plate 14 generate mutually repulsive magnetic forces. When the plurality of conductive protrusions 141 are not pressed, the plurality of conductive turns 141 do not touch each of the corresponding key contacts i27. When a certain pressing protrusion 142 is pressed to be pressed by the external force to be greater than a magnetic force, the conduction protrusion 141 is moved toward a direction opposite to the one of the button contacts 127 and thus the first contact of the button contact 127 A contact 1 270 and a second contact 1271 are in contact with each other and electrically connected between the first contact 1270 and the first contact 1271 of the button contact 27. Thus, electrically connected to the first contact 1270 The first conductive line 125 and the second V line 128 connected to the second contact 1271 are electrically connected, so that the identification of the input information can be realized by the processing of the micro processing. When the pressing action disappears, the magnetic force of the repulsion causes the conduction protrusion 141 to return to the original position. Referring to FIG. 3 and FIG. 5 together, the second embodiment of the present invention provides a digital device 100 including a display screen 1, a button module 10 of the first embodiment, a housing 102, and internal components (not shown). Show). The digital device 100 can be a mobile phone. The button module 1 内部 and the internal components are all disposed in the housing 099142908 Form No. A0101 Page 10 of 22 0992074387-0 201225127 0 [0021] 〇 1〇2. The internal components may include conventional components of a digital device such as a microprocessor, a micro memory, a benefit line device, and the like. The housing 1〇2 has a first opening (10) and a plurality of second openings 104 for exposing the display surface of the display screen 101. The second opening 104 is for exposing the button mode The plurality of groups 10 press the protrusions 142. The button molds (4) and the first opening 103 are connected by internal component signals, so that the input device of the digital device can be realized by pressing the plurality of pressing protrusions 142. In this case, the information corresponding to the input information is displayed on the display screen 101. Of course, the field (4) q can be understood. When the button module 1G does not press the stone 142, the second opening 1G4 exposes the button mode. The portion of the conductive protrusion 141 can also realize the rounding of the information when pressing. In addition, the housing 102 may not have the second opening 1〇4, and the elastic pressing portion may be disposed at a portion corresponding to the second magnetic plate 14, or The housing (10) can be made entirely of a flexible material. In summary, only the housing 1〇2 has a pressing structure corresponding to the conduction protrusion 141, so that the operator can press the button module (7). The pressing structure can be Second as shown above The port 1 〇 4 can be an elastic pressing portion, and can also be other structures for facilitating the pressing of the conduction protrusion 141. [0022] The button module 10 of the present technical solution has a first magnetic plate "and a second magnetic plate 14," The two magnetic plates 14 have conduction protrusions 141 opposite to the key contacts 127. The mutually repulsive magnetic force between the first magnetic plate π and the second magnetic plate 14 causes the conduction protrusions 141 on the second magnetic plate 14 to automatically come out of contact with the key contacts 127 when the pressing action disappears. The digital device 100 having the button module μ has a simple structure, is easy to assemble, and has a long service life. [0023] In summary, the present invention has indeed met the requirements of the invention patent, and is legally proposed. 099142908 Form No. A0101 Page 11 of 22 0992074387-0 201225127 Patent application.
