[0003] 目前已有以震动器产生震动以提供使用者按压回馈的设计,但此设计通常是在既有的按键结构加设震动器,或是震动器与按键结构的整合具有复杂的电路及支撑设计,不利于薄型化。 [0003] In currently existing vibrators to vibrate to provide the user presses the back design, but this design is typically added vibrators disposed in both key structure, or integrated with the key structures of the vibration having a complicated circuit and support design is not conducive to thin. 再者,行动装置,例如平板电脑或智慧型手机之萤幕键盘,在手指触碰时虽然会提供震动回馈,提示使用者己完成按压操作。 Moreover, mobile devices, such as tablet or smartphone of the on-screen keyboard, when the finger touches, although it will provide vibration feedback, prompt the user has to complete the pressing operation. 然而,此类提供震动回馈的装置通常是使整个装置一起震动,或是使装置的某个面震动,无法提供独立与局部的回馈,不利于操作确认。 However, such apparatus is generally provided vibration feedback so that the entire apparatus with shaking or vibration means so that a face can not separate the local feedback, it is not conducive to the operation confirmation.

[0004] 此外,由于此类键盘在使用者按压时并无有效的力传递路径,常导致下方感应区因未感受到按压力而无法有效地被触发。 [0004] Further, since the user presses the keypad when such no effective force transmission path, often resulting in the sensing region under the pressing force due to not feel can not be effectively triggered. 另一方面,感应区内之感应线路亦有可能因上述震动器或其他机构的加入,却在不应该被触发时被触发了,而产生了错误的触发信号。 On the other hand, sensing area of ​​the sensing lines also may be due to shock or added to the other institutions, but when it should not be a trigger is triggered, an error occurred while triggering signal.

[0048] 力传导单元150,特别是突出部154,较佳由硬度70A以下的缓冲材,更佳由硬度10A 〜60A的缓冲材,藉由雷射或热压模技术所制成。 [0048] The force transmitting unit 150, a projecting portion 154 in particular, the cushioning material preferably a hardness of 70A or less, more preferably a hardness of 10A ~60A cushion material, by laser or hot press techniques made. 于一实施例,力传导单元150由例如硅胶材料所制成。 In one embodiment, the force transmitting unit 150 is made of a material such as silica gel. 亦即,力传导单元150可为软性材料,以免设置于感应单元160上时会因其自身的重量而使感应单元160在键帽层110未被按压的情况下产生误触信号。 That is, the force transmitting unit 150 may be a soft material, is provided in order to avoid an induction unit 160 due to their own weight sensing unit 160 generates the signal if inadvertently the key cap layer 110 is not pressed. 如上所述,力传导单元150用以传递按压力至其下方的感应单元160,以触发感应单元160输出触发信号T。 As described above, the force transmitting unit 150 for transmitting the pressing force to the sensing unit 160 below it, in order to trigger the sensing unit 160 outputs a trigger signal T. 于此实施例,按压力可通过键帽层110及突出部154传递;当键帽区受压迫时,突出部154的底面155即压迫感应单元160而产生触发信号T。 In this embodiment, the pressing force can be transmitted through the projection 110 and the key cap layer 154; oppression when the keycap zone, the bottom surface 154 of the projecting portion 155 that is to be oppressive unit 160 generates a trigger signal T. 于一实施例,如图1B所示,突出部154的外侧壁较佳为实质对准键帽区112的边界,或略大于键帽区112的边界,藉此当使用者按压于键帽区112的边界时,亦可有效通过突出部154向下传递按压力,但不以此为限。 In one embodiment, shown in Figure 1B, outer wall 154 of the projecting portion is preferably aligned with the substance of the key top boundary region 112, or slightly larger than the key cap boundary region 112, whereby when the user presses the key top region on boundary 112 may effectively transfer a pressing force by the downwardly protruding portion 154, but is not limited thereto.

[0049] 如图1A至图1B所示,支撑层140设置于膜片部152上且具有开口140a,使得突出部154位于开口140a。 [0049] As shown in FIGS. 1A-1B, the support layer 140 is disposed on the diaphragm portion 152 and has an opening 140a, the opening 154 such that the projecting portion 140a. 亦即,开口140a较佳为对应键帽层110的键帽区112且范围涵盖环绕容置区152a的突出部154,而使得支撑层140设置于膜片部152上时,突出部154位于开口140a中(如图1B所示)。 That is, the opening 140a corresponding to the range of preferably 112 and 110 of the key cap layer covering the key top region 154 surrounding the protruding portion 152a of the accommodation area, so that when the supporting layer 140 is disposed on the diaphragm portion 152, projecting portion 154 located in the opening in 140a (FIG. 1B). 于此实施例,支撑层140的硬度较佳大于力传导单元150的硬度。 In this embodiment, the hardness of the support layer 140 is preferably greater than the hardness of the force transmitting unit 150. 换言之,支撑层140的设置可确保使用者按压键帽层110时不会因为力传导单元150的硬度太低而变形压缩容置空间150a。 In other words, the support layer 140 may be provided to ensure that no force transmitting unit 150 is too low hardness compression deformation of the accommodating space 150a when the user presses the key cap layer 110.

[0050] 于一实施例,当力传导单元150的突出部154穿设于支撑层140的开口140a时,支撑层140的顶面较佳实质等于或略高于突出部154的顶面158,以供支撑键帽层110,且减少误触发生的机会,但不限于此。 [0050] In one embodiment, when the projecting portion 154 of the force transmitting unit 150 through the opening 140a provided in the support layer 140, the top surface of the support layer 140 is preferably equal to or slightly higher than the substance of the protruding portion of the top surface 158,154, for supporting the key cap layer 110, and reduce the chance of inadvertently occur, but is not limited thereto. 于一实施例,支撑层140的开口140a较佳对应键帽区112,亦即开口140a的形状、大小、位置较佳与键帽区112对应,以使得使用者按压于键帽区112时可确保藉由力传导单元150的力传递部分(例如突出部154)传递按压力至感应单元160。 When in an embodiment, the openings 140a corresponding to the preferred region of the support layer 140 of the key cap 112, i.e., the opening 140a of the shape, size, position 112 corresponds with the preferred keycap region, so that the user region 112 may be pressed against the keycap by the force transmitting unit to ensure that the force transmitting portion 150 (e.g., the protruding portion 154) is transmitted to the pressing force sensing unit 160.

[0051] 如图1C所示,当外界施加按压力F时,按压力F通过力传导单元150向下传递以触发感应单元16〇,使得感应单元160输出触发信号T到控制电路170。 [0051] 1C, when the pressing force F is applied to the outside, the pressing force F is transmitted through the force transmitting means 150 downwardly to trigger the sensing unit 16〇, so that the sensing unit 160 outputs a trigger signal T to the control circuit 170. 亦即,当使用者按压按键结构100时(例如按压于键帽层110的键帽区112时),藉由力传导单元150的结构特性(例如突出部154的底面155压迫感应单元16〇),按压力通过上述的途径向下传递以触发感应单元160发出触发信号T,触发信号T较佳作为操作按键结构1〇〇以输入相应的字元或指令的感应信号。 That is, when the user presses the key structure 100 (such as pressing a key cap layer 110 in the region of the key cap 112), by the structural characteristics of the force transmitting unit 150 (e.g., the bottom surface 154 of the projecting portion 155 to be oppressive means 16〇) , the pressing force by the above route is passed down to trigger the sensing unit 160 emits a trigger signal T, the trigger signal T as an operation key structure 1〇〇 preferred to enter the corresponding characters or instructions sensing signal.

[0052] 再者,感应单元ieo的感应线路较佳为对应于力传导单元150的力传递部分(例如突出部lf54的底面155)设置,以使得按压力仅藉由上述途径传递,而不会通过支撑层140传递,进而降低误触邻近按键的感应区165的可能性。 [0052] Further, the sensing unit ieo induction line preferably corresponding to the force transmitting portion (e.g. the bottom surface of the protruding portion lf54 155) disposed in the force transmitting unit 150, so that the pressing force is transmitted by the routes described above only, and not passing through the support layer 140, thereby reducing inadvertently adjacent key likelihood sensing area 165. 具体而言,感应单元160为薄膜式开关(membrane),如图1A所示。 Specifically, the sensing unit 160 is a thin film switch (membrane), shown in Figure 1A. 作为感应单元160的薄膜式开关具有感应区165,其形状较佳与突出部154的形状近似,例如与突出部154的底面155形状对应。 160 as an induction unit having a membrane-type switch sensing region 165, which is the preferred form the shape of the protruding portion 154 of the approximation, for example, the bottom surface 155 corresponding to the shape of the projecting portion 154. 如图1A所示,由于突出部154 围绕着矩形空间的三边设置而形成类似U字形,因此感应区165的形状亦随之为围绕矩形空间的三边设置,而形成类似U字形的形状。 1A, since the protruding portion 154 provided around three sides of the rectangular space formed similar to a U-shape, so the shape of the sensing region 165 will also be set to surround three sides of the rectangular space, and a shape similar to a U-shape. 然而在不同实施例中,由于突出部154亦可形成为环形或其他形状,因此感应区165亦可随之改变分布的形状。 However, in other embodiments, since the projecting portion 154 can be formed as a ring or other shape, the sensing region 165 will also change the shape of the distribution.

[0053]如图2所示,作为感应单元16〇的薄膜式开关由第一薄膜161、第二薄膜162及间隔层1G8叠合而成,其中间隔层ie8夹设于第一薄膜iei及第二薄膜162之间。 [0053] 2, the sensing unit as a membrane-type switch 16〇 by the first film 161, second film 162 and the spacer layer composite made of 1G8, wherein the spacer layer is sandwiched between the first film ie8 second iei 162 between the two films. 第一薄膜161及第二薄膜162上分别形成有金属线路163,而形成感应区165内的开关线路。 Metal lines 163 are formed on the first film 161 and the second film 162 to form the switch circuit 165 within the sensing region. 如图2所示,第一薄膜lei上的金属线路103与第二薄膜162上的金属线路163呈交错设置,因此所组成的开关线路从上方俯看即形成为网格形状。 2, the metal lines 163 on the metal lines 103 on the first film and the second film 162 lei disposed in a staggered, so the circuit composed of the switch from the top looking down i.e., formed in a mesh shape.

[0055] 具体而言,力传导单元150具有容置空间150a供容置触觉产生器130。 [0055] Specifically, force transmitting unit 150 having a receiving space 150a for accommodating haptic generator 130. 电路层120用以电连接触觉产生器130,并提供驱动触觉产生器130的电路径,使得控制电路170可通过电路层120电连接触觉产生器130。 Circuit layer 120 for electrically connecting the haptic generator 130, and a haptic generator supplies a drive electrical path 130, so that control circuit 170 can be connected to a haptic generator 130 by an electrical circuit layer 120. 如上所述,感应单元160较佳为开关式感应单元,当感应单元160被按压触发时,感应单元160可输出触发信号T,进而使控制电路170产生(1)使用者输入字元或指令的感应信号,及(2)驱动触觉产生器130震动的驱动信号D。 As described above, the sensing unit 160 is preferably a switch-mode sensing unit, the sensing unit 160 when the trigger is pressed, the sensing unit 160 may output a trigger signal T, thereby enabling the control circuit 170 generates (1) the user inputs characters or instructions 130 vibration drive signal sensing signal, and (2) a haptic generator drive D. 电路层120的下表面对应键帽区112具有至少第一接点122a及至少第二接点124a,其中第一接点122a与第二接点124a电性隔离。 The lower surface of the circuit layer 120 corresponding to the key top 112 has at least a first region 122a and at least a second contact contacts 124a, 122a wherein the first contact and the second contact 124a is electrically isolated. 至少一触觉产生器130位于力传导单元150的容置空间150a中,且电连接第一接点部122a及第二接点124a。 In 150a, and 122a is electrically connected to a first contact portion 124a and a second contact at least a haptic generator 130 is located in the force transmitting unit 150 of the receiving space. 感应单元160被触发时可输出触发信号T,而控制电路170于接收触发信号T后,会输出驱动信号D给触觉产生器130,以驱动触觉产生器130发生震动(详见图3D的相关说明)。 After sensing unit 160 may output a trigger signal is the trigger T, the control circuit 170 to receive the trigger signal T, a drive signal is output to the D haptic generator 130 to drive the generator 130 instructions haptic vibration occurs (see FIG. 3D ).

[0056] 再者,本发明于此所述的“触觉产生器”泛指可受驱动信号D驱动而提供触觉回馈(例如震动)的元件。 [0056] Further, according to the present invention herein "haptic generator" refers receiving element driving signal D may provide tactile feedback driver (e.g., vibration) of. 触觉产生器可包含,例如但不限于:压电致动器(Pi ezoelectric actuator)、声圈致动器(voice coil actuator)、震动马达(pager motor)、电磁震动器(solenoid)或其他类型的触觉产生器。 The haptic generator may comprise, for example, but not limited to: a piezoelectric actuator (Pi ezoelectric actuator), a voice coil actuator (voice coil actuator), the vibration of the motor (pager motor), an electromagnetic shaker (Solenoid) or other type of tactile generator. 压电致动器具有非常薄且小的优点,因此非常适合用于多层式薄膜结构的按键结构。 The piezoelectric actuator has the advantage that very thin and small, so it is suitable for the key structure of the multilayer thin-film structure. 于后,以压电致动器为例,说明本发明的按键结构各元件的细部结构及相互作用。 After, to the piezoelectric actuator to illustrate the detailed structure of the key structure of the present invention, the elements and interaction.

[0057] 如图3A至图3C所示,键帽层110覆盖于电路层120上,且键帽层110具有键帽区112 及周边区114,其中周边区114邻接于键帽区112的周围。 [0057] FIGS. 3A to 3C, the key cap layer 110 covers the circuit layer 120, and the key cap layer 110 having a key cap 112 and a peripheral region 114 surrounding the peripheral zone 112 wherein zone 114 adjacent to the keycap . 键帽区112对应触觉产生器130并作为供使用者按压的区域,且周边区114用于连接下方的电路层120。 Keycap corresponding to the haptic region 112 and the generator 130 as an area for a user presses, and the surrounding region 114 for connecting the circuit layer 120 below.

[0058] 键帽层110的厚度较佳为0.075〜2mm,且较佳为软性材质,软性材质因为键帽区112的按压挠曲对于接受触觉回馈亦可提供较佳的效应。 Thickness [0058] of the key cap layer 110 is preferably 0.075~2mm, and preferably soft material, because the soft material is pressed keytop regions 112 for receiving the deflection can provide better tactile feedback effect. 当键帽区112的按压挠曲越大时, 键帽区112对应按压点的厚度越小,使得将能量传递至使用者(例如手指)的路径越短,有利于减少触觉产生器130发生震动时的动能损耗。 When the keycap larger deflection region 112 is pressed, corresponding to the thickness of the key top region of the pressing point 112 is smaller, so that the energy transfer path to the user (e.g., a finger) is shorter, it helps to reduce the occurrence of vibration haptic generator 130 when the kinetic energy loss. 键帽层110的材料可包含例如聚酯(PU)、热塑聚酯(TPU)、皮革、织物、硅胶等。 Material of the key cap layer 110 may comprise, for example, polyester (PU), thermoplastic polyesters (TPU), leather, fabrics, silica and the like.

[0059] 电路层120较佳为相对较硬的材料所构成的薄片形式,以作为载置触觉产生器130 的基板。 [0059] The circuit layer 120 is preferably relatively hard material in the form of a sheet composed, as the mounting substrate 130 haptic generator. 电路层120的厚度较佳为0.05〜0_5圓,且电路层120可由绝缘层及设置于绝缘层的导电路径线路所构成,其中绝缘层可由例如聚对苯二甲酸乙二醋(Polyethylene Terephthalate,PET)所构成。 Thickness of the circuit layer 120 is preferably 0.05~0_5 circle, and the circuit layer 120 may be disposed on the insulating layer and the insulating layer formed of a conductive circuit path, wherein the insulating layer may be formed, for example, polyethylene terephthalate vinegar (Polyethylene Terephthalate, PET ) posed. 换言之,电路层120的硬度大于键帽层11〇的硬度,且电路层120的厚度较佳小于键帽层110的厚度。 In other words, the hardness of the circuit layer 120 is greater than the hardness 11〇 key cap layer, and the thickness of the circuit layer 120 is preferably less than the thickness of the key cap layer 110. 如图3A及图3B所示,电路层120设置于键帽层110下方,其中电路层120的下表面对应键帽区II2具有电隔离的至少一第一接点122a及至少一第二接点124a,以供电连接触觉产生器130。 3A and 3B, a circuit layer 120 is disposed below the key cap layer 110, wherein the lower surface of the circuit layer 120 corresponding keycap II2 region having at least one electrically isolating at least a first contact 122a and second contact 124a, in the haptic generator 130 connected to the power supply. 具体而言,电路层120具有提供驱动信号D传递至触觉产生器130的第一电路径122及第二电路径124,其中第一电路径122及第二电路径124 电隔离地设置于电路层120的下表面,且分别包含第一接点122a及第二接点124a。 Specifically, the circuit layer 120 having a drive signal D is transmitted to a first haptic generator 122 and the electrical path 130 of the second electrical path 124, wherein the first and second electrical paths 122 electrically isolates electrical paths 124 provided on the circuit layer the lower surface 120, respectively comprising a first and second contact points 122a and 124a. 亦即,第一电路径122及第二电路径124设置于电路层120背向于键帽层11〇的一侧(即下侧),以使得触觉产生器130及键帽层110分别设置电路层120的两相对侧。 That is, a first electrical path 122 and a second electrical path 124 to the circuit layer 120 is disposed on a side facing away (i.e., lower side) of the key cap layer 11〇, the haptic generator 130 so that the key cap layer 110 and the setting circuit respectively opposite sides of the layer 120.

[0060]于此实施例,触觉产生器130由压电材料所构成,且较佳为片状形式,其中压电材料可包含例如压电单晶体、压电多晶体(压电陶瓷)、压电聚合物、或压电复合材料,但不以此为限。 [0060] In this embodiment, the haptic generator 130 composed of a piezoelectric material, and preferably in the form of a sheet, which may comprise a piezoelectric material such as piezoelectric single crystal, polycrystal piezoelectric (piezoelectric ceramic), piezoelectric polymer, or a piezoelectric composite material, but not limited thereto. 触觉产生器130设置于电路层120下方,且电连接第一电路径122的第一接点122a及第二电路径124的第二电接点124a,使得驱动信号D可经由电路径122、124传递,以驱动触觉产生器130产生应变而提供触觉回馈(例如震动)。 The haptic generator 130 is provided below the circuit layer 120, and electrically connected to a first level and a second path 122 of the first contact 122a and a second electrical path 124 contacts 124a, so that the drive signal D may be transmitted via the electrical path 122, to drive a haptic generator 130 generates strain provides tactile feedback (e.g., vibration). 在此需注意,触觉产生器130较佳仅藉由第一接点122a及第二电接点124a实体连接于电路层120,以使得触觉产生器130具有较大震动效应。 It should be noted here, only the preferred haptic generator 130 by a first contact 122a and a second electrical contact 124a is connected to the physical layer circuit 120, the haptic generator 130 so that the vibration having a large effect. 亦即,触觉产生器13〇可藉由例如银胶、焊锡等电连接材料连接第一接点122a及第二电接点124a,进而达到实体连接电路层120,使得触觉产生器130未连接电路层120的部分具有较大的震动效应。 That is, the haptic generator 13〇 material may be electrically connected by, for example, silver paste, solder or the like connected to the first contact 122a and a second electrical contact 124a, thus achieving the physical connection circuit layer 120, such that the haptic generator 130 is not connected to the circuit layer 120 the part has a greater shock effect. 然而,于其他实施例,除了藉由第一接点122a及第二电接点124a外, 触觉产生器130可藉由其他黏着方式加强与电路层120的实体连接,以防止触觉产生器130 自电路层120脱离但仍保有预期的触觉回馈效应。 However, in other embodiments, except by the first contact 122a and a second electrical contact 124a, the haptic generator 130 can enhance physical circuit connected to the other layer 120 by adhesive manner, to prevent the layer 130 from the haptic generator circuit 120 out of but still retain the desired tactile feedback effects. 再者,触觉产生器130相对于电路层120的震动方向可包含例如上/下蝶式震动或水平伸缩式震动,且振动方式可包含例如连续震动或脉冲式震动,但不以此为限。 Further, the haptic generator 130 with respect to the vibration direction of the circuit layer 120 may comprise, for example, upper / lower horizontal butterfly telescopic shock or vibration, and the vibration mode may comprise, for example, a continuous vibration or shock pulse, but not limited thereto.

[0061]如图3A至图3C所示,力传导单元150设置于电路层120下方,且力传导单元150具有容置空间150a,其中触觉产生器130位于容置空间150a中。 [0061] FIGS. 3A to 3C, the force transmitting unit 150 is disposed below the circuit layer 120, and a force transmitting unit 150 has an accommodating space 150a, wherein the haptic generator 130 located in the accommodating space 150a. 具体而言,力传导单元150包含膜片部152及突出部K4,其中膜片部I52具有容置区152a,突出部154设置于容置区152a周围并自膜片部152突起,以定义容置空间150a供容置触觉产生器130。 Specifically, the force transmitting unit 150 includes a diaphragm portion 152 and the projecting portion K4, wherein the diaphragm has an accommodating region I52 portion 152a, the protruding portion 154 disposed around the accommodation area from the diaphragm portion 152a and the projection 152 to define a receiving space 150a for accommodating haptic generator 130. 于此实施例,膜片部152 具有通孔以作为容置区152a。 In this embodiment, the diaphragm portion 152 has a through hole to serve as accommodation area 152a. 换言之,触觉产生器130容纳于通孔中。 In other words, the haptic generator 130 is accommodated in the through hole. 如图3A及图3B所示,当容置区15¾对应键帽区112为矩形时,突出部154可环绕容置区152a的三个侧边设置,仅保留设置第一接点l22a及第二接点124a之侧边未设置突出部154。 3A and 3B, when the accommodating area 15¾ keycap corresponding to a rectangular area 112, projecting portion 154 may surround three sides of the accommodating area 152a is set, leaving only a first contact point and second contact l22a side 124a of the projecting portion 154 is not provided. 于其他实施例,当容置区152a对应键帽区112为圆形时,除对应第一接点122a及第二接点124a的位置外,突出部154 可实质环绕容置区152a的所有周边。 In other embodiments, when the accommodating area 152a corresponding to the key top 112 is circular zone, in addition to a position corresponding to the first contact 122a and second contact 124a, the protruding portion 154 may be substantially all around the periphery of the accommodation area 152a.

[0062]当力传导单元150作为电路层120的支撑结构层时,突出部154的厚度较佳大于触觉产生器130的厚度。 [0062] When the force transmitting unit 150 as a support structure layer 120 of the circuit layer, the thickness of the projecting portion 154 is preferably greater than the thickness of the haptic generator 130. 当触觉产生器130于容置空间150a震动时,突出部154的厚度足以提供触觉产生器130适当的震动空间(即触觉产生器130的下方具有足够空间)。 When the haptic generator 130 in the accommodating space 150a vibration, the thickness of the projecting portion 154 of the generator 130 is sufficient to provide the proper tactile vibration space (i.e., below the haptic generator 130 has sufficient space). 此外,支撑层140 的厚度较佳大于触觉产生器130的厚度,以确保触觉产生器130震动的空间。 Further, the thickness of the support layer 140 is preferably greater than the thickness of the haptic generator 130 to secure a space for the haptic vibration generator 130. 换言之,支撑层140的设置可确保使用者按压键帽层110时使触觉产生器130具有足够的震动空间,而不会因为力传导单元150的硬度太低而变形压缩容置空间150a,进而使得触觉产生器130压抵感应单元160而无法发生震动回馈。 In other words, the support layer 140 may be provided to ensure that the haptic generator layer 110 the user presses the key cap 130 has a sufficient vibration space, and not because of the force transmitting unit 150 is too low hardness compression deformation accommodating space 150a, thereby making the haptic generator 130 is pressed against the sensor unit 160 and vibration feedback can not occur. 具体而言,支撑层140的厚度取决于触觉产生器130的厚度及震动空间的高度。 Specifically, the thickness of the support layer 140 depends on the height and thickness of the vibration generating haptic space 130. 举例而言,当震动空间的高度大于例如〇.8mm时,触觉产生器130会具有较佳的震动效果。 For example, when the height of the space is larger than 〇.8mm vibration, the haptic generator 130 will have better effects such as vibration. 因此,支撑层140的厚度较佳设计为大于触觉产生器130的厚度且在按压时能于触觉产生器130下方保有高度大于0.8mm的震动空间。 Thus, the thickness of the support layer 140 is preferably designed to be larger than a thickness of the haptic generator 130 and can be pressed in at the bottom of the haptic generator 130 to maintain the space height is greater than the vibration of 0.8mm.

[0063] 再者,于一实施例,力传导单元150更具有延伸部156,其中延伸部156自突出部154 朝容置空间150a内侧延伸,且延伸部156的顶面低于突出部154的顶面。 [0063] Further, in one embodiment, the force transmitting unit 150 further has an extension portion 156, wherein portion 156 extending from the projecting portion 154 toward the inside of the accommodating space 150a extends, and extends below the top surface 156 of the projecting portion 154 the top surface. 如图3C所示,当触觉产生器130容置于容置空间150a时,触觉产生器130较佳部分重叠延伸部156或抵靠于延伸部156。 3C, when the 150a, haptics generator 130 accommodated in the accommodating space of generator 130 preferably partially overlap extension 156 or the extension portion 156 abuts against. 换言之,延伸部154的顶面较佳高于膜片部152的上表面且低于触觉产生器130的底面,且延伸部154较佳朝容置空间150a内侧延伸至部分触觉产生器130下方。 In other words, the top surface of the extension portion 154 is preferably higher than the upper surface of the diaphragm portion 152 and lower than the bottom surface of the haptic generator 130, and extending portion 154 is preferably toward the inside of the accommodating space 150a extends to a portion below the haptic generator 130. 藉此,力传导单元150向上突起的突出部154于键帽层110下方提供触觉产生器130震动的空间(例如150a), 且延伸部156提供触觉产生器130发生震动时的局部支撑,以免触觉产生器130压抵感应单元160〇 Accordingly, the projecting portion 150 projecting upward force transmitting unit 154 provides a space (e.g., 150a) is the haptic vibration generator 130 below the key cap layer 110, and the extending portion 156 to provide localized support haptic generator 130 when vibration occurs, in order to avoid haptic generator 130 is pressed against the sensing unit 160〇

[0064] 再者,于一实施例,如图3C所示,按键结构100更包含黏着层180,其中黏着层180设置于键帽层110下表面且位于键帽区112之外,以黏着键帽层110及电路层120。 [0064] Further, in one embodiment, shown in Figure 3C, the key structure 100 further includes an adhesive layer 180, wherein the adhesive layer 180 disposed on the lower surface of the key cap layer 110 and the key cap is located outside the area 112 to the adhesive bond cap layer 110 and the circuit layer 120. 具体而言,黏着层180仅设置于键帽层110对应于周边区114的下表面。 Specifically, adhesive layer 180 is provided only on the key cap layer 110 corresponding to the lower surface of the peripheral region 114. 换言之,黏着层180并未设置于键帽层110对应于键帽区112的下表面,使得键帽区112及电路层120对应键帽区112的部分不黏着在一起(或有空隙)。 In other words, the adhesive layer 180 disposed on the key cap layer 110 does not correspond to the region of the lower keycap surface 112, such that the keycap 112 and the circuit region 120 corresponds to the key cap layer region portion 112 is not adhesive together (or voids). 藉此,当触觉产生器130受到驱动信号D的驱动而震动时,可以减少触觉产生器130发生震动时的动能损耗。 Whereby, when the haptic generator 130 is driven and the drive signal D shock can be reduced when the kinetic energy loss haptic generator 130 to vibrate. 亦即,若电路层120与键帽层110全部都黏起来时, 触觉产生器130的「负载」加重,不易产生震动,而使得动能损耗加大。 That is, if the circuit layer 120 and the key cap layer 110 all stick together, haptic generator 130 to "load" increase, easy to produce vibrations, so that the kinetic energy losses increase. 于此实施例,黏着层180的厚度较佳小于0.5mm,但不以此为限。 The thickness of this embodiment, the adhesive layer 180 is preferably less than 0.5mm, but not limited thereto. 再者,按键结构100的其余元件(例如电路层120、 力传导单元150、感应单元160等)之间亦可藉由黏着方式固定,以定位各元件间的相对位置。 Furthermore, among the remaining elements (e.g., circuit layer 120, force transmitting 150, the sensing unit 160 unit, etc.) the key structure 100 may also be secured by adhesive, to locate the relative positions of the elements.

[0065]如图3D所示,当外界施加按压力F时,按压力F通过力传导单元150向下传递以触发感应单元160,使得感应单元160输出触发信号T到控制电路170。 [0065] shown in Figure 3D, when the pressing force F applied from the outside, the pressing force F by the downward transfer force transmitting unit 150 to trigger the sensing unit 160, so that the sensing unit 160 outputs a trigger signal T to the control circuit 170. 控制电路170接收触发信号T而可输出驱动信号D给触觉产生器130进而驱动触觉产生器130发生震动。 The control circuit 170 receives the trigger signal T and the drive signal D to output a haptic generator 130 in turn drives the haptic generator 130 to vibrate. 亦即,当使用者按压按键结构100时(例如按压于键帽层110之键帽区112时),支撑层140在按压力的作用下使触觉产生器130仍有足够的震动空间,且藉由力传导单元150的结构特性(例如突出部154、延伸部156),按压力通过上述的两种途径向下传递以触发感应单元16〇发出触发信号T,触发信号T 一方面作为操作按键结构100以输入相应的字元或指令的感应信号,同时亦作为产生驱动信号D的指示信号,使得控制电路170接收触发信号T而发出驱动信号D。 That is, when the user presses the key structure 100 (e.g., the key cap is pressed against the region 112 of the key cap layer 110), the support layer 140 so that the haptic generator under the action of the pressing force is still sufficient vibration space 130, and by by the structural features (e.g., the protruding portion 154, extension 156) force transmitting unit 150, the pressing force by the above two ways to trigger the sensing units passed down a trigger signal T 16〇, the trigger signal T on the one hand as an operation key structure 100 corresponding to the input character or command detection signal, but also generates a drive signal as an indication signal D, so that the control circuit 170 receives the trigger signal T to emit a drive signal D. 当触觉产生器130经由电路层120的电路径(例如第一电路径122及第二电路径124)接收到来自控制电路170的驱动信号D时,触觉产生器130可于容置空间150a中产生震动,以提供使用者确认按压的震动回馈。 The haptic generator 130 receives the drive signal D from the control circuit 170 via an electrical path (e.g., a first electrical path 122 and the second electrical path 124) when the circuit layer 120, the haptic generator 130 may generate in the accommodating space 150a vibration, in order to provide the user presses the confirmation of vibration feedback.

[0066] 再者,于前述实施例中,延伸部156为沿突出部154朝容置空间l5〇a内侧连续延伸的形式。 [0066] Further, in the foregoing embodiment, the extension portion 156 in the form of a projecting portion 154 toward the inside of the accommodating space continuously extending l5〇a. 然而,于其他实施例,如图3E所示,延伸部156'可为沿突出部lf54'朝容置空间150a 内侧不连续延伸的形式,以配合实际需求增加按键结构的设计弹性。 However, other, forms the extension portion 156 'may be in the protruding portion lf54' toward the inside of the accommodating space 150a extending discontinuously embodiment, shown in Figure 3E, in order to meet the actual demand for increased design flexibility key structure.

[0067] 如图4A及图4B所示,于另一实施例,本发明提供一种包含多个前述实施例的按键结构的输入装置10。 [0067] FIG. 4A and 4B, in another embodiment, the present invention provides a configuration of a key input device 10 of the embodiment comprises a plurality of the foregoing. 在此需注意,于此实施例,输入装置10以键盘装置为例进行说明,但于其他实施例,输入装置可包含一个以上的按键结构且以任何合宜的方式配置,不以实施例所示为限。 Here should be noted that, in this embodiment, the input device 10 will be described as an example keyboard device, but in other embodiments, the input device may comprise one or more key structure and arranged in any convenient manner, not illustrated in Example limit. 再者,于此实施例,输入装置10以包含图3A的按键结构为例说明,但不以此为限。 Further, in this embodiment, the input device 10 comprises a key structure in FIG. 3A as an example, but not limited thereto.
