具体实施方式 Detailed ways

[0059] 请参照图1,其绘示依照本发明实施例的一种键盘的示意图。 [0059] Referring to FIG 1, which illustrates a schematic diagram of a keypad in accordance with an embodiment of the present invention. 键盘10包括多个按键100与键盘控制器(图1中未绘示,例如图5A所示的微处理器44)。 Keyboard 10 comprises a plurality of keys and a keyboard controller 100 (not shown in FIG. 1, for example a microprocessor 44 shown in FIG. 5A). 当按键100被按压力被按压时,键盘控制器:(I)产生对应于此按键100的感测值,此感测值与此按压力的大小相关。 When the button 100 is pressed by the pressing force, a keyboard controller: (I) generating the key corresponding to this sensed value of 100, this sensed value associated with this magnitude of the pressing force. ⑵键盘控制器用以利用对应至按键100的补偿值对此感测值进行补偿,以产生调整后感测值。 ⑵ keyboard controller configured to utilize the compensation value corresponding to the key 100 of this sensing value compensated to produce sensed values ​​adjusted. (3)若此调整后感测值大于等于目前门坎值,则键盘控制器判断按键100被按压,并输出对应至此按键100的按键码(Key Code)。 (3) If this sensed value is greater than the adjusted threshold value equal to the current, the keyboard controller 100 determines a key is pressed, and outputs a key code to this key (Key Code) 100 a.

[0060] 本实施例可藉由调整目前门坎值来让键盘10能够依使用者的需求调整使按键100导通的按压力道,以增加键盘10的适应性与使用上的弹性与便利性。 [0060] The present embodiment can adjust the current threshold value by the keyboard 10 to enable the key 100 is turned on by the pressing force of the user needs to adjust the track, to increase the flexibility and adaptability and convenience in using the keyboard 10. 而且,本实施例可以让工厂所生产的本发明的实施例的多个键盘10具有较高程度的按键导通的按压力道的均一性。 Further, the present embodiment can make more keyboard embodiments of the present invention is manufactured at the facility 10 having a pressing force higher degree of uniformity of the channel buttons turned. 兹进一步详细说明如下。 Hereby described in further detail below.

[0061] 本实施例提出两种于按键100以一按压力被按压后,产生与按压力的大小相关的感测值的按键设计方式。 [0061] The present embodiment proposes two embodiments to the key 100 is pressed after a pressing force is generated and the key design approach sensed values ​​related to pressure by size. 第一种按键设计方式请参照第2A〜2B图,其完整详细结构请参照102214524号中华民国专利申请案的具体内容。 A first key design embodiment Referring first to FIG 2A~2B, the entire contents of the specific detailed structure, refer to ROC Patent Application No. 102214524 cases. 图2A绘示依照本发明实施例的每个按键具有多个子接触点的键盘,其中,每个子接触点具有彼此间隔的上电极与下电极。 FIG 2A shows a keyboard having a plurality of contact points in accordance with each of the sub-key embodiments of the present invention, wherein the contact point of each sub having an upper and lower electrodes spaced apart from each other. 如图2A所示,键盘10上具有多个按键,键盘10包括键帽层110、开关膜层120与底板150。 2A, having a plurality of keys on the keyboard 10, the keyboard 10 includes a key cap layer 110, a switch layer 120 and the base plate 150. 开关膜层120包括上薄膜电路层122、下薄膜电路层126以及隔离层124。 Switch thin film layer 120 includes an upper circuit layer 122, the thin film circuit layer 126 and the spacer layer 124. 键帽层110上的键帽区域供使用者按压。 Keycap area 110 for the user presses the key cap layer. 每一个键帽区域与开关膜层120的一个按键开关对齐。 Each keycap a key region 120 of the switching switch alignment film. 例如键帽区域102与开关膜层120的按键开关20对齐,其中按键开关20包含上薄膜电路层122上的对应区域104、下薄膜电路层126上的对应区域108以及隔离层124上的区域106。 E.g. keycap layer region 102 and the switch 120 is aligned with the key switch 20, in which the key switch 20 comprises a region corresponding to the thin film 104 on the upper circuit layer 122, corresponding area in the lower thin film layer 126, a circuit region 108 and the spacer layer 124,106 .

[0062] 接着,请参照图2B,其绘示依照本发明实施例在键盘10的相邻四个按键所对应的开关膜层120中的四个按键开关的示意图。 [0062] Then, referring to FIG 2B, which shows a schematic view of the four key switches 120 of switch membrane layer adjacent embodiment four keys of the keyboard 10 corresponding to the embodiment according to the present invention. 兹以相邻的四个按键为“1”、“2”、“Q”、及“W”四键为例说明之,其分别对应至按键开关20、30、40及50。 Hereby adjacent four buttons of "1", "2", "Q", and "W" as an example of the four-button, which respectively correspond to the key switches 30, 40 and 50. 上薄膜电路层122具有多条上电极,例如是上电极El〜E5。 Thin film circuit layer having a plurality of upper electrode 122, for example, the upper electrode El~E5. 多个上电极形成于上薄膜电路层122的下表面上。 A plurality of upper electrodes formed on a lower surface of the upper thin-film circuit layer 122. 多条上电极成条状,并且沿着第一方向延伸,例如,沿着垂直方向延伸。 A plurality of upper electrodes into strips, and extending along a first direction, e.g., extending in the vertical direction. 下薄膜电路层126具有多条下电极,例如是下电极Jl〜J5。 The thin-film circuit layer having a plurality of lower electrodes 126, for example, the lower electrode Jl~J5. 多条下电极形成于下薄膜电路层126的上表面。 A plurality of electrodes are formed on the lower surface of the lower thin-film circuit layer 126. 多条下电极成条状,并且沿着第二方向延伸,例如是沿着水平方向延伸。 A plurality of lower electrodes into strips, and extending along a second direction, for example, extending in the horizontal direction. 其中,第一方向不平行于第二方向以便形成复数个交叉点。 Wherein the first direction is not parallel to the second direction so as to form a plurality of intersections.

[0063] 于图2B中,于开关膜层120中,单一按键“I”对应至按键开关20,单一按键“2”对应至按键开关30,单一按键“Q”对应至按键开关40,单一按键“W”对应至按键开关50。 [0063] in FIG. 2B, in the switching layer 120, a single button "I" corresponds to the key switch 20, a single key "2" corresponds to the key switch 30, a single key "Q" corresponds to the key switch 40, a single button "W" corresponds to the key switch 50. 此夕卜,开关膜层120对应于单一按键“I”的按键开关20具有多个子接触点Pl-Pn,例如:子接触点Pl位于上电极El和下电极J2的交叉点。 Bu this evening, the switch 120 corresponding to a single layer key "I" of the sub-key switch 20 having a plurality of contact points Pl-Pn, for example: a sub contact point Pl located at the intersection of the lower electrode and the upper electrode El of J2. 当按键“I”未被按压时,子接触点Pl-Pn均未导通;以子接触点Pl为例,即上电极El和下电极J2彼此保持上下分离而未导通。 When the button "I" is not pressed, the contact sub-points Pl-Pn no conduction; an example of sub-contact point Pl, i.e., the upper electrode and the lower electrode El J2 held vertically separated from each other without conducting. 反之,当按键“ I ”被按压时,子接触点Pl-Pn中的至少部分会承受按键“ I ”的施力而被挤压并导通,且被导通的子接触点的个数与按键“I”被按压的按压力的大小相关。 Conversely, when the key "I" is pressed, the sub contact point Pl-Pn at least partially receiving the key will force the "I" is pressed and turned on, is turned on and the number of contact points with the sub key "I" is related to the magnitude of the pressing force of the pressing.

[0064] 更具体而言,由图2B可看出子接触点Pl与P2位于上电极El上,子接触点P3至P5位于上电极E2上,子接触点P6至P7位于上电极E3上。 [0064] More specifically, it can be seen from Figure 2B the contact points Pl and P2 promoter located on the upper electrode El, the sub contact point P3 to P5 is located on the upper electrode E2 of the sub to the contact point P6 P7 located on the upper electrode E3. 因此,当按键“I”被按压而挤压到部分子接触点时,这些被挤压的子接触点所对应的上电极与下电极彼此靠近并接触,而使得这些被挤压的子接触点导通。 Thus, when the key "I" is pressed to the contact point pressed into the sub-section, which is pressed into contact sub-points corresponding to the upper and lower electrodes close to each other and in contact, such that the contact point of the sub-extruded turned on. 例如,当使用者以较轻的力量按压按键“I”时,对应至按键“I”的键帽区域102的键帽层110的向下运动的运动量较小或变形的变形量较小,进而使按键“I”对应的开关膜层120的按键开关20的上薄膜电路层122与下薄膜电路层126彼此接触的面积较小,被按压到的子接触点的个数较少,使得可被导通的子接触点的个数也较少。 Movement amount of downward movement of the key cap layer 102, for example, 110, when the user presses the buttons with a light strength of "I", to the key corresponding to the "I" region keycap smaller or lesser amount of deformation of the deformation, and further so the button "I" corresponding to the key switch 120 of the switching film on a small area of ​​thin-film circuit layers 20 122 126 contact with the lower thin-film circuit layers from each other, is pressed against the smaller number of sub-contact points, that can be number of sub conductive contact points less. 反之,当使用者以较重的力量按压按键“I”时,对应至按键“I”的键帽区域102的键帽层110的向下运动的运动量较大或变形的变形量较大,进而使按键“I”对应的开关膜层120的按键开关20的上薄膜电路层122与下薄膜电路层126彼此接触的面积较大,被按压到的子接触点较多,使得可被导通的子接触点的个数也较多。 A large amount of deformation or deformation amount of movement downward movement of the key cap layer 102, 110 on the contrary, when the user presses the power button heavier "I", corresponds to the key "I" keycap larger areas, and further so the button "I" corresponding to the key switch 120 of the switching layer on the thin film 122 larger area of ​​the circuit layer 126 contact with the lower thin-film circuit layers 20 to each other, is pressed against the contact points are more child, it can be turned so that the number of child contact points is greater. 藉此,可以藉由不同的力道按压按键“1”,以改变按键开关20中的子接触点的导通个数,以改变按键“I”所对应的电阻值。 Accordingly, the force can be different by pressing the button "1" to change the number of conductive sub-key switch contact points 20 to change the resistance value of the key corresponding to "I". [0065] 在电路图中,这些子接触点可分别用电阻和开关等组件代表之。 [0065] In the circuit diagram, the contact points may be sub represent only resistors and switches and other components. 如图3A所示,其绘示图1的按键“I”所对应的等效电路图。 3A, which illustrates an equivalent circuit view of the key of "I" corresponds. 子接触点Pl-Pn分别以子电阻Rl-Rn及子开关Sl-Sn等效之。 Pl-Pn-contacting point of each sub-sub-resistors Rl-Rn and equivalents of switches Sl-Sn. 子电阻Rl-Rn分别与子开关Sl-Sn电性耦接。 Partial resistance Rl-Rn are the sub switches Sl-Sn is electrically coupled. 当子接触点被导通,对应的子开关将会导通。 When the sub contact point is turned on, the corresponding sub-switches will be conducting. 当按键“I”被施以一较轻的按压力道Fl时,因为按压的接触面积较小,导通的子接触点的个数较少,故可被导通的子开关亦较少,例如仅导通开关S1-S3。 When the button "I" is applied with a pressing force lighter road Fl, because a small contact area pressing, the fewer the number of sub conductive contact points, it can also be less sub-switch is turned on, for example, only conducting switches S1-S3. 而当按键“I”被施以一较重的按压力道F2时,则可因为按压的接触面积较大而导通较多的并联子开关,例如导通子开关Sl-Sn。 When the button "I" is subjected to a heavy pressing force F2 when the channel may be larger because the contact area of ​​the pressing turned more parallel switches, for example, the sub-switch is turned on Sl-Sn. 图3A所示的按键“I”所对应的等效电路图亦可等效成图3B所示的包括可变电阻Rll与开关Sll的等效电路图,其中,可变电阻Rll的大小与被导通的子开关所对应的子电阻有关。 FIG 3A is an equivalent circuit diagram shown in FIG key "I" may be equivalent to the corresponding equivalent circuit diagram of FIG. 3B includes a variable resistor Rll with the switch Sll shown, wherein the size of the variable resistor Rll is turned corresponding to a sub-sub-switch resistance associated.

[0066] 因此,不同的按压力道可使按键“I”整体具有不同的电阻值R11。 [0066] Thus, the different channels can key pressing force "I" as a whole has a different resistance values ​​R11. 当按压力道使得对应的调整后感测值与目前门坎值的数值关系满足预设条件时,则键盘将输出对应至按键“I”的按键码。 When the pressing force corresponding to the channel so that the adjusted value and the sensed value of the current threshold value satisfies a preset condition, the output corresponds to the keyboard keys "I" key code. 由于子电阻Rl-Rn为并联,按压的力道越大,则导通越多的并联子开关,按键“I”整体的电阻值Rll越小,即按键“I”整体的电阻值Rll与按压力道成反比,可将目前门坎值设定为电阻值,又由于按键“I”整体的电阻值Rll随着按压力道的增大逐渐变小,可将预设条件定义为调整后感测值小于等于目前门坎值时,则键盘将输出对应至按键“I”的按键码。 Since in parallel, the greater the resistance Rl-Rn sub pressing force, and then turned more parallel switches, buttons "I" smaller overall resistance Rll, Rll i.e. the overall resistance of the button pressing force "I" Road inversely proportional to the current threshold value can be set to a resistance value, since the keys and "I" the overall resistance Rll channel increases as the pressing force became smaller, the predetermined condition may be defined as the adjustment is less than the sensed value when equal to the current threshold value, it outputs a corresponding keyboard key to the "I" key code. 又由于对于同一按键“I”而言,电阻值Rll越小,电流值则越大,而电阻值Rll与按压力道成反比,则电流值与按压力道成正比,故可将目前门坎值设定为电流值,且预设条件定义为调整后感测值大于等于目前门坎值时,则键盘将输出对应至按键“I”的按键码。 Also, because the same key for the "I", Rll smaller resistance value, the current value is larger, the resistance value is inversely proportional to channel and Rll pressing force, the pressing force proportional to the current value of the channel, so the current threshold value may be set when the current value, and the predetermined condition is defined as greater than the adjusted sensing value equal to the current threshold value, it outputs a corresponding keyboard key to the "I" key code.

[0067] 另外,第二种按键设计方式于按键中使用压阻材料(Piezo Resistive Material)部件。 [0067] Further, the second embodiment using the key design piezoresistive material (Piezo Resistive Material) to the key member in the. 请参照图4,其绘示依照本发明实施例的使用压阻材料部件的按键“1”、“2”、“Q”、及“W”四键的示意图。 Referring to Figure 4, a schematic view of "1", "2", "Q", and "W" key four piezoresistive material used according to the key member of the present invention, an embodiment thereof shown. 按键“ I”、“2”、“Q”、及“W”分别以代号K_1、K_2、K_Q、K_ff代表之。 Key "I", "2", "Q", and "W" respectively to code K_1, representatives of K_2, K_Q, K_ff. 压阻材料的电阻值随着所承受的压力而改变。 As the resistance value of the piezoresistive material of the pressure change. 按键的压阻材料部件的阻抗值与按压力的大小相关。 The resistance value of the piezoresistive material member keys related to the size of the pressing force. 于图4中,压阻材料以一可变电阻等效之。 In FIG. 4, piezoresistive material with a variable resistance of an equivalent. 当按键被按压后,可变电阻会依据按压力道改变可变电阻的电阻值。 When the key is pressed, the variable resistor can change the resistance value of the variable resistor according to the pressing force of the road. 使用压阻材料部件的第二种按键设计方式的按键同样地可以使用一个可变电阻与一个开关等效之。 Key member piezoresistive material using a second key aspect of the design can be used similarly to a variable resistor with an equivalent of a switch. 举例来说,图3B所示的电路亦可作为第二种按键设计方式的按键“I”的等效电路。 For example, the circuit shown in FIG. 3B may be used as a second key button design mode "I" of the equivalent circuit. 当此按压力道所对应的调整后感测值与目前门坎值的数值关系满足预设条件时,键盘将输出对应至按键的按键码。 When this adjustment of the pressing force corresponding to the channel sensing value and the current value of the threshold value satisfies a preset condition, the output of the corresponding keyboard key to the key code. 由于可变电阻会依据按压力道改变可变电阻的电阻值,可将目前门坎值设置为电阻值或者电流值,并设置相应的预设条件,与第一种按键设计方式的原理类似,不另赘述。 Since the variable resistor changes the resistance of the variable resistor according to the pressing force path, the current threshold value can be set to a resistance value or a current value, and set the corresponding preset condition, with the first principle of the key design similar manner, not another repeat.

[0068] 兹将键盘中不同位置的按键具有不同阻抗值的原因说明如下。 [0068] The reason is hereby keyboard keys at different positions having different impedance values ​​described below. 请参照图5A及图5B,图5A及5B绘示依照本发明实施例的键盘10的等效电路图。 Referring to FIG. 5A and FIG. 5B, FIG 5A and 5B illustrate equivalent circuit diagram of an embodiment according to the present invention, the keyboard 10. 每个按键由一个可变电阻与一个开关等效之,例如按键“I” (以代号K_1代表之,或称为第一按键)由可变电阻Rll与开关Sll等效之,而按键“Q” (以代号K_Q代表之,或称为第二按键)由可变电阻R21与开关S21等效之。 Each key consists of a variable resistor with an equivalent of a switch, such as key "I" (the code K_1 representatives of, or referred to as first key) is equivalent to the variable resistor Rll with the switch Sll, the key "Q "(K_Q representative of the code, the second key, or referred to) variable resistor R21 and the switch S21 is equivalent. 键盘10还包括第一多任务器41、第二多任务器42、模拟数字转换器43及微处理器44。 Keyboard 10 further includes a first multiplexer 41 and second multiplexer 42, an analog to digital converter 43 and microprocessor 44. 微处理器44可执行键盘控制器轮流扫描键盘所有按键的功能。 Microprocessor 44 alternately scan the keyboard controller may perform all the keyboard buttons. 如图5A所示,当(I)按键K_1被按下时,开关Sll被导通,且⑵微处理器44扫描到按键K_1 (亦即使第一多任务器41选择导通走线LO且第二多任务器42选择导通走线LI)时,电压源Vcc会透过走线LO与走线LI,把按键K_1对应的电流IO传送至第二多任务器42 ;此时导通按键1(_1时的电流IO所看到的的整体阻抗值与可变电阻R11、走线LO的长度、走线LI的长度相关。电流IO流经第二多任务器42,模拟数字转换器43将电流IO大小转换为数字信号,再将数字信号传送至微处理器44。 5A, when (I) K_1 button is depressed, the switch Sll is turned on, and the microprocessor 44 scans the key ⑵ K_1 (also even if the first multiplexer 41 selects the conductive trace and the first LO when more than two MUX 42 selects the conductive traces LI), the voltage source Vcc will go through wiring line LO and LI, corresponding to the key K_1 current IO delivered to the second multiplexer 42; key 1 is turned on at this time (current IO _1 seen when the overall resistance value of the variable resistor R11, the length of the wire to go LO, LI is related to the length of the trace. current IO flowing through the second multiplexer 42, the analog to digital converter 43 IO current magnitude into a digital signal, and then transmits the digital signal to the microprocessor 44.

[0069] 类似地,如图5B所示,当⑴按键K_Q被按下时,开关S21被导通,且⑵微处理器44扫描到按键K_Q (亦即使第一多任务器41选择导通走线L2且第二多任务器42选择导通走线L3)时,电压源Vcc会透过走线L2与走线L3,把按键K_Q对应的电流Il传送至第二多任务器42 ;此时导通按键K_Q时的电流Il所看到的整体阻抗值与可变电阻R21、走线L2的长度、走线L3的长度相关。 [0069] Similarly, as shown in FIG 5B, when K_Q ⑴ key is depressed, the switch S21 is turned on, and the microprocessor 44 scans the key ⑵ K_Q (also even if the first multiplexer 41 selects turned away when the line L2 and the second multiplexer 42 selects the conductive traces L3), the voltage source Vcc will go through the line L2 and the trace L3, a current corresponding to the key K_Q Il transferred to a second multiplexer 42; in this case when conduction current Il key K_Q seen overall resistance value of the variable resistor R21, take the length of the line L2, L3 of the length of the associated trace. 接着,电流Il流经第二多任务器42,模拟数字转换器43将电流Il大小转换为数字信号,再由模拟数字转换器43将数字信号传送至微处理器44。 Next, the current Il flowing through the second multiplexer 42, an analog to digital converter 43 converts the size of the current Il to a digital signal, and then transmits the digital signal by the analog to digital converter 43 to the microprocessor 44.

[0070] 由上述可知,由于走线LO加上LI (或称为第一路径)的总长度,和走线L2加上L3 (或称为第二路径)的总长度不同,因此按键K_1和按键K_Q所对应的阻抗值亦不相同。 [0070] From the foregoing, since the wiring LO plus LI (or called a first path) of the total length, and L2 together with different trace L3 (or referred to as a second path) of the total length, and thus the key K_1 K_Q key corresponding to the resistance value is not the same. 由此可以看出,由于键盘中的每一个按键的位置不同,其所对应的走线的总长度亦不相同,使得按键导通时,电流所流经的路线所对应的整体阻抗亦不相同。 It can be seen, due to the different position of each keyboard key, the total length of its corresponding trace is not the same, so that when the key is turned on, current flows through a route corresponding to the total impedance is not the same . 如此,即使供给按键的电压源一样均是电压Vcc,当使用者以相同力量来按压不同按键时,其所产生的对应电流亦会因整体阻抗值的不同而不同,使得模拟数字转换器43输出的数字值亦会不同。 Thus, even if the supply voltage source as the keys are the voltage Vcc, when the user presses the same power to different keys, it produces a corresponding current also differ from the total impedance values ​​differ, so that the analog-digital converter 43 outputs the numeric value will be different. 也就是说,即使于不同按键上施以相同按压力道,每个按键被按压后所产生的整体等效阻抗值与数字值亦不相同,该数字值例如是电流值或者电压值等。 That is, even when subjected to the same key on different channels pressing force, the overall equivalent resistance value of the digital values ​​generated by each key is pressed is not the same, for example, the digital value is a current value or a voltage value.

[0071 ] 图6绘示图5A及图5B的按键K_1、K_Q及K_W被按压后,电流所流经的路线所对应的整体等效阻抗值的可能示意图。 [0071] FIG. 6 illustrates a view of the key K_1 5A and FIG. 5B, and after K_Q K_W is pressed, may schematic overall equivalent resistance value of the current flowing through the corresponding route. 当按键K_1被按下时,其对应的整体等效阻抗值与走线LO与LI的阻抗值之和相关。 When the button is pressed K_1 overall equivalent impedance value which corresponds to the trace LO and LI and related impedance values. 类似地,按键K_Q被按下时,其对应的整体等效阻抗值与走线L2与L3的阻抗值之和相关。 Similarly, when the button is pressed K_Q overall equivalent impedance value which corresponds to the trace impedance value L2 and L3 and related. 由于键盘中的每一个按键因其位置不同,使得对应的走线长度和不同,故对应的走线的阻抗值之和亦不相同,所对应的整体等效阻抗值亦不相同。 Because each key in the keyboard because of their different positions, such that the corresponding trace lengths and different, so that the corresponding values ​​of the impedances of the traces and is not the same, the entire corresponding equivalent impedance value is not the same. 因此即使施以相同按压力量,每个按键被按压后所产生的整体等效阻抗值亦不相同。 Therefore, even if subjected to the same pressing force, the overall equivalent impedance values ​​each generated key is pressed is not the same. 由图6可以看出,即使施以相同按压力道,按键K_1、K_Q及K_W被按压后所产生的整体等效阻抗值不相同。 As can be seen from Figure 6, even if the pressing force applied the same channel, the key K_1, the overall equivalent impedance value K_Q K_W is pressed and the generated different.

[0072] 请参照图7,其绘示图6的按键K_1、K_Q及K_W施以预设校正按压力时,其对应所传导电流值经由模拟数字转换之后所得的数字值的示意图。 [0072] Referring to FIG 7, a schematic diagram of the key K_1 6, K_Q and K_W preset correction applied pressing force, a schematic diagram of a digital value via the analog-digital conversion obtained after a value which corresponds to the conduction current. 产生此数字值的一种方式为,分别施加该预设校正按压力于所有按键上,并于所有按键所对应的导通电流流过的走线的两个端点间施加相同电压Vcc (例如于第一多任务器41与第二多任务器42之间),然后量测流过按键的电流大小(例如是按键K_1所对应的电流10)。 One way to generate this digital value, correcting the predetermined pressing force is applied on all buttons respectively, the voltage Vcc is applied between the same two endpoints and all keys corresponding conduction current flows traces (e.g., in between the first multiplexer 41 and second multiplexer 42), and then measuring the amount of current flowing through the key (e.g., a current corresponding to the key K_1 10). 并将此电流大小经由模拟数字转换(Analog to Digital Conversion, ADC)之后,便可得到各个按键的电流值Dl、D2及D3,基本上各个按键的电流值会和各个按键的等效阻抗值成反比。 After this and the magnitude of the current through the analog to digital converter (Analog to Digital Conversion, ADC), each key can be obtained current values ​​Dl, D2 and D3, the current value is substantially of each key and each key is equivalent to the impedance value inversely proportional. 然本发明并不限于以量测电流值来实施本发明,其它以计算电压方式产生此数字值的方式亦可应用于本实施例中。 However, the present invention is not limited to the embodiment to measure the current value of the present invention, other digital values ​​to calculate a generated voltage in this manner can also be applied in the embodiment of the present embodiment.

[0073] 微处理器44可对键盘10执行校正程序,以针对上述的每个按键对应至不同整体等效阻抗值的情况进行校正。 [0073] The microprocessor 44 may perform the calibration procedure for the keyboard 10, to the entire case corresponds to a different value for the equivalent impedance is corrected above each key. 以表I数值来举例说明此校正程序。 Values ​​in Table I to illustrate this calibration procedure.

[0074] 首先,如表I〜表2所示,对键盘的多个按键分别施加该预设校正按压力SI为70克(g),预设的校正用门坎值THl的电流值为0.7A。 [0074] First, as shown in Table 2. Table I~, a plurality of keys of the keyboard are applied to the preset pressing force correction SI of 70 g (G), the current preset threshold value THl correction value 0.7A . 微处理器44扫描各个按键(亦即如图5A及图5B所示,轮流建立LO与L1、L2与L3...等电流路径),产生分别对应至此些按键的多个校正用感测值。 The microprocessor 44 scans each key (i.e., 5A and 5B, in turn establish LO and L1, L2 and L3 ... etc. current path), generating a corresponding plurality of keys so far these correction values ​​are sensed . 此校正用感测值例如为图7所示分别对应至按键K_1、K_Q及K_W的数字值Dl (I量测_1为0.6A)、D2 (I量测_Q为0.5A)、及D3 (I量测_ff为0.4A)。 This correction example in FIG. 7 by sensing value corresponding to the key shown K_1, K_Q and K_W digital value Dl (I _1 measurement of 0.6A), D2 (I _Q measurement of 0.5A), and D3 (I _ff measurement of 0.4A). 此外,于下述表1~到7中,将按键导通时,电流所流经的绕线部份所对应的路径为R路径,电流所流经的开关(即可变电阻部份)表示为R开关,I量测代表校正用感测值,I补偿代表补偿值,于其后不再赘述之。 Further, in the following Table 1 to 7, when the key is turned on, current flows through a winding path portion corresponding to the path R, the current flowing through the switch (ie variable resistance portion) is is R switch, the I measurement value representative of the sensed calibration, a compensation value representing the I compensation, after it omitted.

[0080] 如图8所示,其绘示图7的按键K_l、K_Q及K_W的校正用感测值及校正用门坎值THl (0.7A)的示意图。 [0080] As shown, in which the key shown in FIG K_l 7, and the correction K_Q K_W schematic THl (0.7A) 8 with a threshold value and correcting the sensed value. 于图8中,将门坎值THl (0.7A)作为校正用门坎值,分别减去这些校正用感测值D1、D2及D3,其所得的差异,便是分别对应至这些按键的多个补偿值。 In Figure 8, the threshold value THl (0.7A) as a correction threshold value, subtracting the correction value sensed D1, D2 and D3, that the resulting difference is compensated corresponding to the plurality of keys value. 亦即,各按键的补偿值与对应的各按键的校正用感测值的总和,等于门坎值TH1。 That is, each key of each key and the offset value corresponding to the sum of the correction sensed value equal to threshold value TH1. 例如,按键K_1的补偿值CPl由门坎值THl减去校正用感测值Dl而得到I补偿_1为0.1A,按键K_Q的补偿值CP2由门坎值THl减去校正用感测值D2而得到I补偿_Q为0.2A,而按键K_W的补偿值CP3由门坎值THl减去校正用感测值D3而得到I补偿_W为0.3A。 For example, the key K_1 compensation value is subtracted from the threshold value THl CPl correction Dl obtained sensing value of 0.1A _1 I compensation, the compensation value is subtracted from the key K_Q CP2 of THl threshold value correction obtained sensing value D2 I _Q compensation is 0.2A, and the compensation value of the key K_W CP3 correction value D3 to obtain a sensed compensated _W is 0.3A I is subtracted from the threshold value THl. 然后可将各按键的补偿值、作动门坎值、及各按键的按键码储存于键盘控制器中。 Each key may then be compensation value actuation threshold value, and each key of the key codes stored in the keyboard controller.

[0081 ] 如此,藉由此校正程序,可以让每个按键在接受到预设校正按压力SI为70g时,所产生的校正用感测值(I量测)加上补偿值(I补偿)的总和等于门坎值THl为0.7A。 [0081] Thus, by this correction program, so that each key can be corrected at a preset pressing force received SI is 70g, the generated correction value sensed (I measured) plus the offset value (I compensation) the sum is equal to the threshold value THl 0.7A. 此补偿值可用以补偿不同按键之间整体等效阻抗值不同所造成的电流差异。 This compensation value used to compensate for the overall equivalent resistance value between the different key differences caused by different currents. 之后,在键盘正常操作时,即可将按键被按压时所产生的电流感测值(数字值)加上此补偿值,即可对各按键的不同的阻抗值进行补偿。 Thereafter, during normal operation of the keyboard, the key can be pressed when the generated current sensed value (digital value) adding this compensation value, the resistance value can be different for each of the keys to compensate.

[0082] 如表3所示,当各按键接收到S2为80g时,80g大于该预设校正按压力70g时,各按键量测所得电流加大,使得各按键加总补偿后的数字值I_total(亦即补偿后的数字值 [0082] As shown in Table 3, when S2 is received when each of the keys 80g, 80g is larger than the predetermined pressing force correction when 70g, each key resulting measured current is increased, so that the digital value of each of the keys after I_total sum compensation (i.e., the digital value after compensation

1.total等于I量测加上I补偿)都能大于门坎值TH1,微处理器44判断这三个按键确实已经被按压。 1.total I equal to I plus the compensation measurement) can be greater than the threshold value TH1, the microprocessor 44 determines indeed three buttons has been pressed.

[0083] 如表4所示,当各按键接收到S3为60g时,60g小于该预设校正按压力70g时,各按键量测所得电流降低,使得各按键加总补偿后的数字值(亦即补偿后的数字值I_total等于I量测加上I补偿)都小于门坎值TH1,微处理器44判断这三个按键均未被按压。 [0083] As shown in Table 4, when each of the keys is received S3 60g, 60g is smaller than the predetermined pressing force correction when 70g, each key resulting measured current is reduced, so that the digital values ​​of each of the keys summed compensation (also i.e. I_total digital value after compensation is equal to I plus I compensation measurement) are less than the threshold value TH1, the microprocessor 44 determines that none of the three buttons is pressed.

[0088] 当使用者想调整按键导通的按压力道大小时,可以藉由改变目前门坎值来达成。 [0088] When the user wants to adjust the size of the key channel conduction pressing force, by varying the current threshold value can be achieved. 使用者可透过键盘驱动程序或搭配的应用程序来输入门坎值调整要求,而键盘控制器可响应于该门坎值调整要求,来调高或调低目前门坎值,并利用更新后的目前门坎值来判断后续按键是否被按压。 The user may enter through the keyboard driver or application program with a threshold value adjustment request, while the keyboard controller in response to the threshold value adjustment request to raise or lower the current threshold value, and using the updated current threshold value to determine whether a subsequent key is pressed.

[0089] 需要说明的是,本实施例中将电流值作为数字值来加以调整,以使其满足与目前门坎值之间的数值关系,例如加总补偿后的数字值(即电流值)大于等于目前门坎值,则判断按键被按压。 [0089] Incidentally, in the current embodiment of the present embodiment as a digital value to be adjusted so as to satisfy the relationship between the value of the current threshold value, such as digital value (i.e., current value) is greater than the sum of the compensation equal to the current threshold value, it is determined that the key is pressed. 实际操作中,也可以将阻抗值或者电压值来作为数字值,通过调整阻抗值或者电压值来使其满足于目前门坎值之间的数值关系,例如将目前门坎值设定为阻抗值,当加总补偿后的数字值(即阻抗值)小于等于目前门坎值,则判断按键被按压。 In practice, the impedance value or may be a voltage value as a digital value, by adjusting the impedance value or the voltage value to satisfy the relationship in value between the current threshold value, for example, the current threshold value is set to the impedance value, when digital value (i.e. impedance value) of the sum current compensation threshold value or less, it is determined that the key is pressed. 使用者可以根据实际需要自行决定数字值,不以上述为限。 The user can decide a digital value according to the actual needs, it is not limited to the above.

[0090] 请参照图9及表5,其绘示使用者调高目前门坎值至门坎值TH2(0.8A),然后对各按键K_1、K_Q及K_W施以80g按压力,各按键补偿后所得的数字值示意图。 [0090] Referring to FIG. 9 and Table 5, which shows the user the current threshold value to increase the threshold value TH2 (0.8A), then the pressing force of each of the keys K_1, K_Q and subjected K_W 80g, after each key resulting compensated a schematic diagram of a digital value. 由图9及表5可看出,对各按键K_1、K_Q及K_W施以80g按压力时,按键K_1、K_Q及K_W可得到各个按键的电流值Dl'、D2'及D3',由于各按键补偿后所得的数字值分别为0.76A、0.74A及0.72A,这些数位值均小于门坎值TH2 (0.8A),因此键盘控制器判断所有按键均未被按压,如此不会向主机计算机输出对应于这三个按键的按键码。 As can be seen from FIG. 9 and Table 5, when the pressing force of each of the keys K_1, K_Q and subjected K_W 80g, buttons K_1, K_Q K_W available and current values ​​of each key Dl ', D2' and D3 ', since each key the resulting compensated digital values ​​of 0.76A, 0.74A and 0.72A, the digit values ​​are less than the threshold value TH2 (0.8A), a keyboard controller thus determines all the keys have not been pressed, so the host computer does not correspond to the output in these three key of the key code. 如此使用者虽然同样以80g按压力来按压按键:在表3预设的门坎值THl为0.7A状态下,三按键均被判定为导通;但在表5调高目前门坎至门坎值TH2(0.8A)状态下,三按键均被判定为不导通。 Thus the user while also pressing force to 80g pressed keys: values ​​in Table 3 for the next preset threshold THl 0.7A state, three keys are turned on is determined; however, in Table 5 to increase the current threshold TH2 to the threshold value ( under 0.8A) state, it is determined that three buttons are non-conductive.

[0096] 请参照图10及表6,其绘示使用者调低目前门坎值至门坎值ΤΗ3(0.6Α)时,然后对各按键K_1、K_Q及K_W施以60g按压力时,各按键补偿后所得的数字值示意图。 [0096] Referring to FIG. 10 and Table 6, which shows to the user when the lower threshold value ΤΗ3 (0.6Α) current threshold value, and then subjected to pressing force 60g, compensation for each of the keys of each key K_1, K_Q and K_W the resulting digital value. FIG. 由图10及表6可看出,按键K_1、K_Q及K_W施以60g按压力时,可得到各个按键的电流值Dl' '、D2' '及D3' ',各按键补偿后所得的数字值分别为0.64A、0.66A及0.65A,这些数位值均大于门坎值TH3 (0.6A),因此键盘控制器判断这三个按键均被按压,如此会向主机计算机输出对应于这三个按键的按键码。 Can be seen in FIG. 6 and Table 10, the button K_1, K_Q 60g and K_W applied pressing force, the current value of each key can be obtained Dl '', D2 'digital values ​​obtained after each of the keys compensation' and D3 '', are 0.64A, 0.66A and 0.65A, the digit values ​​are greater than the threshold value TH3 (0.6A), a keyboard controller thus determines three buttons are pressed, will thus correspond to three buttons output to the host computer key code. 如此使用者虽然同样以60g按压力来按压各按键:在表4预设的门坎值THl状态下,三按键均被判定为不导通;但在表6调低目前门坎值为门坎值TH3状态下,三按键均被判定为导通。 Thus the user while also pressing force of 60g each key pressed: In Table 4, the preset threshold value THl state, it is determined that three buttons are not conducting; Table 6 but lower current threshold value is the threshold value TH3 state , the three buttons are turned on is determined. 另外若使用者仅想单独调整某几个按键的按压力道大小时,则可以针对各个按键分别储存门坎值,仅改变特定按键的门坎值来达成。 Further if the user wants only a single channel to adjust the pressing force of the size of a few keys, then the threshold value can be stored separately for each key, only changing the threshold value to achieve a particular key. 然后使用者透过键盘驱动程序或搭配的应用程序来输入各个按键的门坎值调整要求,而键盘控制器可响应于该门坎值调整要求,来调高或调低特定按键的门坎值,并利用更新后的门坎值来判断后续该特定按键是否被按压。 The user then inputs through a keyboard driver or an application with the threshold value adjustment request of each key, the keyboard controller in response to the threshold value adjustment request to increase or decrease the threshold value of a specific key and using update threshold value to determine whether the particular key is pressed subsequent.

[0097] 请参照图11及表7,其绘示各按键K_l、K_Q及K_W各别的门坎值分别为TH_1 (0.6A)、TH_Q(0.7A)、TH_ff(0.8A),然后对各按键K_l、K_Q 及K_W 施以80g 按压力时,各按键补偿后所得的数字值示意图。 [0097] Referring to FIG. 11 and Table 7, which shows each of the keys K_l, K_Q and K_W respective threshold values ​​were TH_1 (0.6A), TH_Q (0.7A), TH_ff (0.8A), then each key K_l, K_Q 80g and K_W applied pressing force, a schematic diagram of a digital value obtained by compensating each of the keys. 由图11及表7可看出,按键K_1、K_Q及K_W施以80g按压力时,可得到各个按键的电流值Dl'、D2'及D3',而各按键补偿后所得的数字值分别为0.76A、0.74A、0.72A,其中按键K_l、K_Q 的数字值分别大于TH_1 (0.6A)、TH_Q(0.7A),因此键盘控制器判断这两个按键被按压;而按键K_w的数字值小于TH_W(0.8A),因此键盘控制器判断按键W未被按压。 7 can be seen from FIG. 11 and Table, buttons K_1, K_Q 80g and K_W applied pressing force, the current value of each key can be obtained Dl ', D2' and D3 ', and the resulting compensated digital values ​​after each of the keys, respectively 0.76A, 0.74A, 0.72A, wherein the key K_l, K_Q of digital values ​​are greater than TH_1 (0.6A), TH_Q (0.7A), a keyboard controller thus determines the two key is pressed; the value is less than the number keys K_w TH_W (0.8A), the controller determines the key W so the keyboard is not pressed. 如此键盘控制器只会向主机计算机输出对应于按键1(_1、1(_0的按键码,但不会向主机计算机输出对应于按键K_W的按键码。如此可以满足使用者的特殊要求:(1)以较低按压力来按压按键K_1、K_Q,便能轻易使按键1(_1、1(_0导通,⑵需要以较高按压力来按压按键K_W,才能使按键K_W导通。 Thus only the keyboard controller corresponding to the host computer 1 outputs to the key (selected, 1 (_0 key code, the key code does not correspond to the key K_W host computer outputs the thus meet the specific requirements of the user: (1 ) lower pressing force to press the key K_1, K_Q, will be able to easily make a key (selected, 1 (_0 turned, ⑵ require a higher pressing force to press the key K_W, to make the key K_W conduction.

[0100] 总而言之,在图5A及图5B的架构下,如表3所示,当按键K_1被按压力FO (70g)按压时,第一路径LO与LI因应传递第一信号。 [0100] In summary, in the architectures of FIGS. 5A and 5B, as shown in Table 3, when the key is pressed K_1 pressing force FO (70g), a first transmission path in response to a first LO signal and LI. 当按键K_Q被按压力H)按压时,第二路径L2与L3因应传递第二信号。 When the key is K_Q) against pressing force H, L2 and L3 of the second path in response to a second transfer signal. 键盘控制器储存第一补偿值1_补偿1(0.1A)及第二补偿值1_补偿Q (0.2A),并将门坎值THl (0.7A)作为作动门坎值,第一按键码〃1"可自第一信号转换出第一信号值I量测1,第二按键码"Q〃可自第二信号转换出第二信号值I量测Q。 Keyboard controller stores the first compensation value compensation 1_ 1 (0.1A) and the second compensation value compensation 1_ Q (0.2A), and the threshold value THl (0.7A) as the actuation threshold value, a first key code 〃 1 "may be converted from the first signal a first measurement signal value I 1, the second key code" signal from the second Q〃 be converted by a second measurement signal value I Q. 当键盘控制器自第一路径LO与LI接收到第一信号,且第一信号值I量测I和第一补偿值1_补偿1(0.1A)相加运算所得结果满足大于或等于作动门坎值THl (0.7A)时,键盘控制器因应第一信号而输出第一按键码〃1〃至一主机(未绘示)。 When the path from the first LO keyboard controller receives the first signal LI, and a first measurement signal value I I and a first compensation value calculation results obtained 1_ compensation 1 (0.1A) is greater than or equal to meet actuator when the threshold value THl (0.7A), a keyboard controller in response to a first signal to output a first key code 〃1〃 to a host (not shown). 当键盘控制器自第二路径L2与L3接收到第二信号,且第二信号值I量测Q和第二补偿值1_补偿Q (0.2A)相加运算所得结果满足大于或等于作动门坎值THl (0.7A)时,键盘控制器因应第二信号而输出第二按键码〃Q〃至主机。 When the keyboard controller L2 and L3 from the second path to receive the second signal and the second signal value I measured Q compensation and the second compensation value Q 1_ (0.2A) obtained by adding the calculation result is greater than or equal to meet actuator when the threshold value THl (0.7A), a keyboard controller in response to a second output a second signal to the host 〃Q〃 key code.

[0101] 如表5所示,其中当作动门坎值被使用者调整提高为TH2(0.8A),导致第一信号值I量测I和第一补偿值1_补偿I相加运算所得结果无法满足大于或等于调整后的作动门坎值TH2(0.8A)时,键盘控制器忽略第一信号而不输出第一按键码〃1〃至主机。 [0101] As shown in Table 5, wherein the threshold value is adjusted as moving a user to improve TH2 (0.8A), resulting in a first measurement signal value I I 1_ and a first compensation value calculation results obtained by adding the compensation I Unable to meet the actuation threshold greater than or equal to the adjusted value TH2 (0.8A), a keyboard controller ignores the first output signal without 〃1〃 first key code to the host.

[0102] 如表4所示,当第一按键(可为复数个按键100的其中之一,下同)被第二按压力(60g)按压时,第一路径因应传递第三信号。 [0102] As shown in Table 4, when the first key (one of which may be plural keys 100, the same below) is the pressing force (60g) is pressed, a first transmission path in response to the second and third signals. 第二按压力小于第一按压力。 A second pressing force smaller than the first pressing force. 键盘控制器还可自第三信号转换出第三信号值I量测1(0.54A)。 Keyboard controller also converts the signal from the third signal a third measurement value I 1 (0.54A). 当键盘控制器自第一路径接收到第三信号,并将门坎值THl (0.7A)作为作动门坎值,且第三信号值(0.54A)和第一补偿值(0.1A)相加运算所得结果未满足大于或等于作动门坎值THl (0.7A)时,键盘控制器忽略第三信号而不输出第一按键码〃1〃至该主机。 From the first path when the keyboard controller receiving the third signal, and the threshold value THl (0.7A) as the actuation threshold value, and a third signal value (0.54A) and the first compensation value (0.1A) addition operation the results are not greater than or equal to meet actuator threshold value THl (0.7A), a keyboard controller ignores the first output of the third signal without 〃1〃 key code to the host.

[0103] 如表6所示,当作动门坎值被使用者调整降低至门坎值TH3(0.6A)时,导致第三信号值(0.54A)和第一补偿值(0.1A)相加运算所得结果满足大于或等于调整后的作动门坎值TH3(0.6A)时,键盘控制器因应第三信号而输出第一按键码〃1〃至主机。 When [0103] As shown in Table 6, as the dynamic threshold value is lowered to a user to adjust the threshold value TH3 (0.6A), resulting in a third signal value (0.54A) and the first compensation value (0.1A) addition operation when the obtained result meets the actuation threshold greater than or equal to the adjusted value TH3 (0.6A), a keyboard controller in response to a first key code to output a third signal to the host 〃1〃.

[0104] 上述可变电阻例如为第一按键下方的多个开关接点。 [0104] The first plurality of variable resistors, for example, under the key switch contacts. 当第一按键被第一按压力按压时,多个开关接点中有M个开关接点导通,该可变电阻的电阻值较低而使该第一信号具有第一电流值。 When the first key is pressed a first pressing force, a plurality of switch contacts has M switching contacts is turned on, a low resistance value of the variable resistor of the first signal having the first current value. 当第一按键被第二按压力按压时,多个开关接点中有N个开关接点导通,该可变电阻的电阻值较高而使该第三信号具有第三电流值,M>N,使得第一电流值大于第三电流值。 When the first key is pressed a second pressing force, a plurality of switch contacts there are N switch contacts is turned on, the higher the resistance value of the variable resistor so that the third signal has a third current value, M> N, such that the first current value is greater than the third current value.

[0105] 举例而言,如图2B所示,上述开关接点例如为子接触点。 [0105] For example, as shown in FIG. 2B, for example, the switch contacts contact point for the child. 若按键100以较重的第一按压力按压时,假设第一按压力导致有5个开关接点导通,若按键100以较轻的第二按压力按压时,假设第二按压力导致有2个开关接点导通。 If the button 100 is pressed when a first heavier pressing force, resulting in a pressing force is assumed that the first switch contact 5 is turned on, if the button 100 is pressed when the lighter second pressing force, assuming that the second pressing force resulting in a 2 a switch contact is turned on. 因此,当按键100以较重的第一按压力按压时,由于被导通的开关接点数较多,并联的电阻较多,使得按键100的等效电阻较小,故以较重的第一按压力按压所导通的第一电流值,会大于以较轻的第二按压力按压所导通的第三电流值。 Thus, when the key 100 is pressed when a first pressing force, since the switch is turned more contact points, the heavier more resistors in parallel, so that equivalent resistance is small button 100, so the first heavier a first pressing force pressing the current conduction, the current value will be greater than the third pressing force pressing the second conductive lighter.

[0106] 于另一个实施例中,更可藉由上述方法将键盘分群组作设定,使得键盘中的某一区按键可依使用者需求做特别的设定。 [0106] in another embodiment, the above method but also by a group as a keyboard sub-set, so that the keys of the keyboard in a zone may vary depending on user needs to do a particular set. 例如于图1中,若使用者较常使用「丨」、「丨」、「一」、「一」等方向键,而需要让此四个按键具有较高的灵敏性。 For example in Figure 1, if the user more frequently used "Shu", "Shu", "a", "an" arrow keys, etc., and we need to make this four keys with high sensitivity.

[0107] 如果要让使用者轻压按键,即能使按键传送出对应的键盘码时,则可利用上述方法,先将键盘10上的所有按键作校正,再针对使用者较常使用「丨」、「丨」、「一」、「一」的此四个方向键,进一步调整对应至此四个按键的作动门坎值。 [0107] If soft reduction to make a user key, a key that would allow the transmission code corresponding to the keyboard, by the above method can, first of all keys on the keyboard 10 for calibration, again more often used for the user "Shu "," Shu "," a "," a "of this four arrow keys to further adjust the threshold value corresponds to this actuation four keys. 例如将此四个按键的作动门坎值设为较小的数值,则此四个按键仅需要较小的按压力道,即可让对应此按压力道所产生的数字值和此四个按键的补偿值运算所得结果较容易满足大于或等于作动门坎值,使按键码被送出。 This example four key actuation threshold value is set to a small value, then this requires only a small four button pressing force road, you can make a digital value corresponding to this pressing force is generated and this channel four buttons a compensation value calculation results obtained are easier to meet actuator threshold equal to or greater than the value of the key code is sent. 藉此可增加此四个按键的灵敏度。 Thereby increase the sensitivity of the four buttons. 反之,若此四个按键的作动门坎值设为较大的数值,则此四个按键需要较大的按压力道,才可让对应此按压力道所产生的数字值和此四个按键的补偿值运算所得结果满足大于或等于作动门坎值。 Conversely, if this four key actuation threshold value is set to a larger value, then the four buttons channel requires a large pressing force before allowing the digital value corresponding to this pressing force is generated and this channel four buttons a compensation value calculation results are greater than or equal to meet actuator threshold value. 在此情况下,此四个按键需要使用者重压才能使按键码被送出,故此四个按键的灵敏度较低。 In this case, the four buttons needed to make the weight of the user key code is sent, therefore the lower the sensitivity of four buttons.

[0108] 其它的按键亦藉由调整对应的作动门坎值,来改变此按键的导通力道的大小。 [0108] Additional buttons also by adjusting the actuating threshold value corresponding to change the size of this pilot channel Kone button. 本实施例可让使用者可更有弹性地依据其需求将键盘分群组,并调整作动门坎值以设定按键导通的力道,藉此可让使用者在打字时或执行其它应用程序(例如计算机游戏等)能具有更佳的使用经验。 This embodiment allows the user more flexibility can be divided according to their needs keyboard group, and adjust the threshold value to set the actuation force of the button is turned on, thereby allowing the user when typing or other application execution (for example, computer games, etc.) can have a better experience.

[0109]当然,本发明还可有其它多种实施例,在不背离本发明精神及其实质的情况下,熟悉本领域的技术人员可根据本发明作出各种相应的改变和变形,但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 [0109] Of course, the present invention may have a variety of other embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding modifications and variations according to the present invention, but these corresponding modifications and variations shall fall within the scope of the appended claims.
