In order to simplify the drawing, FIG. 1A and FIG. 2 only schematically show two buttons 110, but it is emphasized that the keyboard 1A may include a plurality of ^ keys, so the reading amount of the button 11 shown in FIG. The invention is only illustrative and not limiting. In the embodiment, each of the keys 11G can have a receiving groove 114, and each of the first height adjusting members 112 is disposed in the corresponding receiving groove 114. A variable magnetic force is present between each of the first height adjusting members 112 and the second height adjusting member 12G, and the variable magnetic force can cause the respective first height adjusting members m and the second south adjusting members 120 to attract or repel each other. The figure is a schematic cross-sectional view of the keyboard when the respective first-height adjustment members ιΐ2 and the second one are attracted to each other, and the figure m is a schematic cross-sectional view of each of the fresh-height adjustment members 112 and the second height adjustment member (10). When each of the first height adjusting members m and the second height adjusting member 12 are attracted to each other, each of the respective button ιιο is maintained with respect to the first-degree adjusting member 120, and each of the first-height adjusting members 112* is first. ::Two J. : 口 , . , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , And the second height H2 is greater than the first height HI. Specifically, in the present embodiment, the variable magnetic force existing between each of the first height adjusting member n2 and the second height adjusting member 120 can be realized by the following manner. Each of the first height adjusting member 112 and the second height adjusting member 120 has permanent magnetism, and the second height adjusting member 12 is movable in a direction d perpendicular to the first height H1. It is to be noted that the direction d in which the second height adjusting member 120 moves is substantially perpendicular to the direction of the first height H1. Therefore, if the direction d of the movement of the second height adjusting member 12G and the direction of the first twist H1 are affected by the manufacturing tolerance and are slightly non-perpendicular, such a non-vertical condition is also encompassed by the present invention. Fan _. In the above, each of the first height adjusting members 112 may be a metal magnet or a plastic magnet, that is, each of the first height adjusting members 112 has two different magnetic poles, that is, s poles (sp〇le). ) with N pole (N pole). The second adjustment member i2 includes a movable carrier plate 122 and a plurality of magnet blocks 124. Each of the magnet blocks 124 may also be a metal magnet or a plastic magnet, and the internal magnetic field directions of the adjacent magnet blocks 124 are opposite to each other. For example, when the second height adjusting member 12 移动 moves along the direction d to a first position (as shown in FIG. 1A ), the S poles of the respective first height adjusting members 112 correspond to the magnet blocks 124 . One N pole. Thus, the first height adjusting member 112 and the second height adjusting member 120 are attracted to each other, and each of the buttons 11A maintains a lower height first height H1 with respect to the second height adjusting member 120. When the second height adjusting member 120 moves along the direction 4 to a second position 200847745 IPD070131TW 23984twf.doc/n (as shown in FIG. 1B), the s poles of the respective first height adjusting members 112 correspond to the magnet blocks 124. One of the S poles. Thus, the first height adjusting member 112 and the second height adjusting member 120 repel each other, and each of the buttons 110 maintains a second height H2 with a higher height than the second height adjusting member 120. As can be seen from the above, when the user wants to use the keyboard 100a, the user can move the second height adjusting member 120 to the second position (as shown in FIG. 1B) to raise each button 110 to a second height with a higher height. H2. Therefore, the space in which the respective buttons 110 can move becomes large, and the user feels a better tactile feeling when pressing the buttons 110. When the user does not use the keyboard 100a, the user can move the second height adjustment member 120 to the first position (as shown in Fig. 1A) to lower each of the keys 11' to the lower height first height H1. Thus, the thickness of the keyboard 100a is shortened and the overall volume is reduced, and the user can conveniently carry the keyboard l〇〇a or the portable electronic device applying the keyboard l〇〇a. In addition, in the embodiment, the keyboard 10a may further include a circuit board 130, and the circuit board 130 may be disposed between the first height adjusting member η] and the first south adjusting member 120. The function of circuit board 130 is to generate instructions that the user desires to input. When the user presses these buttons 11 ,, the circuit board 130 is triggered by the buttons 110 to emit a signal, and the portable electronic device performs the desired action of the user according to the signal. It should be noted that the circuit board 130 can be disposed in other positions according to design requirements as long as the functions of the first height adjusting member Π 2 and the second south adjusting member 120 to adjust the height of the buttons 11Q are not affected. . Therefore, 9 200847745 IPD070131TW 23984twf.doc/n The position of the circuit board 130 shown in FIGS. 1A and 1B is merely illustrative and does not limit the present invention. Second embodiment

Referring to FIG. 2A and FIG. 2B simultaneously, the main difference of the foregoing embodiment of the keyboard 1 (9) b of the present embodiment is that the second height adjusting member 120 ′ of the keyboard 10 b can have variable magnetic properties, that is, the second height adjusting member 12 〇 It can be an electromagnet. Therefore, the second height adjusting member 12A may have an inductive coil and a magnetic core wound by the induction coil, and the material of the magnetic core may be a ferromagnetic material or a ferrous iron. Ferrimagnetic material FIG. 2A is a schematic cross-sectional view of the keyboard 100b when the first height adjusting member 112 and the second two-degree adjusting member 120' are attracted to each other, and the head 2B is adjusted at each first height for the keyboard io〇b. A cross-sectional view of the piece 112 and the second height adjusting member, which are mutually repelled. In detail, referring to Fig. 2, when the user does not use the keyboard lGGb_, the second height adjusting member 12() does not pass current to generate an induced magnetic field. However, since the second height adjusting member ^, = magnetic ~ has ferromagnetism (^) or ferrimagnetic enthalpy, each of the permanent magnets has a first height-height adjustment: 弟: a brother-degree adjustment member 120, which can mutually attract. Because of the lower first-height m. The younger-111 degree adjustment piece 12G will maintain the height of the field when the user uses the keyboard 100b, and the second height adjustment piece will generate an internal induced magnetic field after the current is turned on in 200847745 i^juu/uijiTW 23984twf.doc/n. And the direction of the induced magnetic field is opposite to the direction of the internal magnetic field of each of the first height adjusting members 112 having permanent magnetism. For example, the s poles of the respective first height adjustment members US correspond to the 8 poles of the second height adjustment member 12A. Thus, the first height adjusting member 112 and the second height adjusting member 12 are mutually repelled, and the buttons 110 maintain a second height H2 relative to the second height adjusting member 120, such as Figure 2B shows. In summary, the present invention changes the thickness of each of the keys by using the variable magnetic force between each of the first height adjusting members and the second south adjusting member. can change. #每按两ς When the height of the second height adjustment member is high, these buttons are not only available for U to make the user feel better.
