Description

按鍵結構Button structure

本發明係有關於一種按鍵結構，更詳而言之，是一種可在按壓過程中發出聲響或觸覺手感的按鍵結構。The present invention relates to a button structure, and more particularly, to a button structure that can emit an audible or tactile feel during pressing.

鍵盤是一種將指令輸入電腦的主要工具，而被電腦使用者廣泛使用。鍵盤通常包括有鍵帽、具有開關的鍵盤是電腦使用上不可或缺的配件，因此，使用者對於鍵盤的功能要求也愈趨嚴格。現在的鍵盤除了要能提供指令輸入之外，還得要對鍵盤的操作提供反饋按壓手感與按壓聲響，以符合鍵盤的各種使用需求，因而遂有機械式鍵盤的設計。然，機械式鍵盤具有機械軸開關(例如：Cherry 機械軸開關)，可用於提供反饋按壓的段落手感(tactile feedback)與按壓聲響(click sound)，機械軸開關具有一定高度而不利於鍵盤薄型化的應用，且機械式鍵盤需設置至少80多顆機械軸開關，而大幅增加鍵盤製作成本。A keyboard is a primary tool for entering commands into a computer and is widely used by computer users. The keyboard usually includes a keycap, and the keyboard with the switch is an indispensable accessory for the use of the computer. Therefore, the functional requirements of the keyboard for the user are becoming stricter. In addition to being able to provide command input, the current keyboard has to provide feedback on the operation of the keyboard, such as pressing and pressing, in order to meet the various needs of the keyboard, and thus the design of the mechanical keyboard. However, the mechanical keyboard has a mechanical axis switch (for example: Cherry mechanical axis switch), which can be used to provide tactile feedback and click sound for feedback pressing, and the mechanical axis switch has a certain height, which is not conducive to thinning the keyboard. The application, and the mechanical keyboard needs to set at least 80 mechanical axis switches, which greatly increases the cost of keyboard production.

對此，有人提出一種非機械式鍵盤的按鍵結構，以取代機械式鍵盤的鍵軸，所述按鍵結構主要係在鍵帽下方設置例如為橡膠圓頂體(Rubber Dome)的向上回復力源與剪刀腳結構，藉由剪刀腳結構使鍵帽按一預定行程移動，且藉由向上回復力源對受到按壓的鍵帽提供彈性回復力，使鍵帽可以回復到按壓前之位置，由於向上回復力源與剪刀腳結構毋須占用過大體積，故此種按鍵結構可作為薄型化鍵盤。然而，非機械式鍵盤的按鍵結構存在以下問題：(1在操作時，受限於結構設計並無法反饋按壓聲響；(2)在操作時，橡膠圓頂體會崩潰而提供崩潰效應手感 (collapse)，由於橡膠圓頂體係為彈性體，故所提供的崩潰效應手感較為柔軟和緩而無阻力變化較大的段落感，無法如同機械式鍵盤的機械軸開關可提供反饋按壓的明確段落手感，因此，相較於非機械式鍵盤的按鍵結構，機械式鍵盤的按鍵結構在操作時具有更明確的段落觸覺手感。In this regard, a key structure of a non-mechanical keyboard has been proposed to replace the key shaft of a mechanical keyboard, which is mainly provided with an upward recovery force source such as a rubber dome under the key cap. The scissor foot structure moves the keycap by a predetermined stroke by the scissor foot structure, and provides an elastic restoring force to the pressed keycap by the upward returning force source, so that the keycap can return to the position before pressing, due to the upward return The force source and the scissor foot structure do not need to occupy an excessive volume, so the button structure can be used as a thin keyboard. However, the key structure of the non-mechanical keyboard has the following problems: (1 in operation, it is limited by the structural design and cannot feedback the pressing sound; (2) during operation, the rubber dome collapses to provide a collapse effect. Since the rubber dome system is an elastic body, the collapse effect provided by the rubber is softer and gentler, and the sense of passage without the resistance changes greatly, and the mechanical shaft switch of the mechanical keyboard can provide a clear paragraph feel of feedback pressing, therefore, Compared with the key structure of the non-mechanical keyboard, the key structure of the mechanical keyboard has a more clear paragraph tactile feel during operation.

因此，如何讓非機械式按鍵的按鍵結構，在操作時也能夠提供類似機械軸開關按壓時的按壓聲響或較強烈明確段落觸覺手感 (tactile feedback)，為本案發明主要解決的技術課題。Therefore, how to make the button structure of the non-mechanical button can provide a pressing sound similar to the mechanical shaft switch pressing or a relatively strong tactile feedback when operating, which is a technical problem mainly solved by the present invention.

本發明主要是提供多種可用於非機械式鍵盤的按鍵結構，使非機械式鍵盤在操作時能夠反饋按壓的段落手感與按壓聲響，以滿足使用者對於鍵盤的功能要求。The present invention mainly provides a plurality of key structures that can be used for a non-mechanical keyboard, so that the non-mechanical keyboard can feedback the pressed hand feel and the pressing sound during operation to meet the user's functional requirements for the keyboard.

第一實施例：First embodiment:

請一併參考圖1至圖3-4，其中，如左列所參考的各圖所示，第一實施例的按鍵結構1包括有電路板11、底板模組12、鍵帽13、剪刀腳結構14、向上回復力源15、抵接塊161與彈性體162。電路板11係具有用於提供觸發訊號的電訊號接點111。鍵帽13係設置於電路板11之電訊號接點111的上方，用於提供按壓而觸發電路板11的電訊號接點111。Referring to FIG. 1 to FIG. 3-4 together, as shown in the drawings referred to in the left column, the button structure 1 of the first embodiment includes a circuit board 11, a bottom plate module 12, a key cap 13, and a scissors foot. The structure 14 is an upward returning force source 15, an abutting block 161 and an elastic body 162. The circuit board 11 has an electrical signal contact 111 for providing a trigger signal. The keycap 13 is disposed above the electrical signal contact 111 of the circuit board 11 for providing a voltage to trigger the electrical signal contact 111 of the circuit board 11.

剪刀腳結構14係引導鍵帽13在高位置HP與低位置LP間移動，當鍵帽13移動到低位置LP時，鍵帽13可觸發電路板11的電訊號接點111，使電訊號接點111處於導通狀態而完成按鍵的觸發。向上回復力源15係設置於鍵帽13與電路板11之間，用於對鍵帽13施加向上回復力FR(例如：磁性力、或彈性力)，以使位於低位置LP的鍵帽13朝向高位置HP移動。更具體而言，向上回復力源15係例如為可提供磁性力的磁性體(例如：互斥磁鐵、或相吸磁性體搭配連桿) 或可提供彈性力的彈性體(例如：彈簧、或橡膠圓頂體 rubber dome) 。The scissor foot structure 14 guides the keycap 13 to move between the high position HP and the low position LP. When the keycap 13 moves to the low position LP, the key cap 13 can trigger the electrical signal contact 111 of the circuit board 11 to make the electrical signal connected. Point 111 is in the on state to complete the triggering of the button. The upward returning force source 15 is disposed between the keycap 13 and the circuit board 11 for applying an upward restoring force FR (for example, a magnetic force or an elastic force) to the keycap 13 so that the keycap 13 located at the low position LP is provided. Move toward the high position HP. More specifically, the upward restoring force source 15 is, for example, a magnetic body that can provide magnetic force (for example, a mutually exclusive magnet or a phase absorbing magnetic body with a connecting rod) or an elastic body that can provide an elastic force (for example, a spring, or Rubber dome body rubber dome).

如圖1所示，剪刀腳結構14具有彼此樞接且可相互轉動的內支臂141與外支臂142，內支臂141具有內支臂開口1411。抵接塊161係一體成形於鍵帽13，而自鍵帽13的底表面向下延伸，而延伸至內支臂開口1411內。當鍵帽13由高位置HP朝向低位置LP移動時，抵接塊161係可隨著鍵帽13的移動而沿著抵接塊移動路徑移動。抵接塊161具有第一抵觸面1611、第二抵觸面1612與抵觸交界點1613，抵觸交界點1613係位於第一抵觸面1611與第二抵觸面1612之間的交界。彈性體162係為沿著抵接塊移動路徑延伸的懸臂彈片且具有彈性抵觸部1623。As shown in FIG. 1, the scissor foot structure 14 has an inner arm 141 and an outer arm 142 that are pivotally coupled to each other and are rotatable relative to each other, and the inner arm 141 has an inner arm opening 1411. The abutting block 161 is integrally formed in the keycap 13 and extends downward from the bottom surface of the keycap 13 to extend into the inner arm opening 1411. When the keycap 13 is moved from the high position HP toward the low position LP, the abutting block 161 is movable along the abutting block moving path as the key cap 13 moves. The abutting block 161 has a first abutting surface 1611, a second abutting surface 1612 and an abutting interface 1613. The abutting interface 1613 is located at a boundary between the first abutting surface 1611 and the second abutting surface 1612. The elastic body 162 is a cantilever elastic piece that extends along the abutting block moving path and has an elastic abutting portion 1623.

於第一實施例中，彈性抵觸部1623係凸出於懸臂彈片的本體靠近抵接塊161的一側，使抵接塊161在移動過程中能夠抵觸彈性抵觸部1623。抵接塊161與彈性體162於內支臂開口1411中沿著抵接塊移動路徑的投影係部分重疊，即彈性體162係位於抵接塊161的抵接塊移動路徑中。In the first embodiment, the elastic abutting portion 1623 protrudes from the side of the body of the cantilever spring near the abutting block 161, so that the abutting block 161 can resist the elastic abutting portion 1623 during the movement. The abutting block 161 and the elastic body 162 are partially overlapped in the inner arm opening 1411 along the projection system of the abutting block moving path, that is, the elastic body 162 is located in the abutting block moving path of the abutting block 161.

於第一實施例中，當鍵帽13受到按壓而由高位置HP朝向低位置LP移動時，可至少包含以下兩階段的移動過程：In the first embodiment, when the keycap 13 is pressed to move from the high position HP toward the low position LP, at least the following two-stage movement process can be included:

(a) 如圖3-1至圖3-3所示，鍵帽13受到按壓會使抵接塊161抵觸彈性體162，如此，抵接塊161係可推抵彈性推抵部1623而使彈性體162受力彈性變形，以令彈性抵觸部1623沿著第一抵觸面1611移動而到達抵觸交界點1613，甚至使彈性抵觸部1623在移動過程中碰撞第一抵觸面1611，以發出聲響或對扺接塊161提供向上推力FU，此時，向上推力FU會與向上回復力源15的向上回復力FR協同，而增加鍵帽13由高位置HP朝向低位置LP移動所需施加的按壓力。(a) As shown in FIGS. 3-1 to 3-3, the key cap 13 is pressed to cause the abutting block 161 to abut against the elastic body 162. Thus, the abutting block 161 can be pushed against the elastic pushing portion 1623 to be elastic. The body 162 is elastically deformed to move the elastic abutting portion 1623 along the first abutting surface 1611 to reach the contact boundary point 1613, and even causes the elastic abutting portion 1623 to collide with the first abutting surface 1611 during the movement to emit a sound or a pair. The splicing block 161 provides an upward thrust FU, at which time the upward thrust FU cooperates with the upward restoring force FR of the upward restoring force source 15 to increase the pressing force required to move the keycap 13 from the high position HP toward the low position LP.

(b) 如圖3-4所示，鍵帽13受到按壓會使抵接塊161抵觸彈性體162，如此，抵接塊161係可推抵彈性抵觸部1623而使彈性體162受力彈性變形，使彈性抵觸部1623經過抵觸交界點1613而沿著第二抵觸面1612移動，甚至使彈性抵觸部1623在移動過程中碰撞第二抵觸面1612，以發出聲響或對扺接塊161提供向下推力FD，此時，彈性體162會解除對抵接塊161提供向上推力FU，甚至，向下推力FD會抵銷向上回復力FR的一部分，而減少鍵帽13由高位置HP朝向低位置LP移動所需施加的按壓力。(b) As shown in FIG. 3-4, the key cap 13 is pressed to cause the abutting block 161 to abut against the elastic body 162. Thus, the abutting block 161 can push against the elastic abutting portion 1623 to elastically deform the elastic body 162. The elastic abutting portion 1623 is moved along the second abutting surface 1612 through the abutting interface point 1613, and even the elastic abutting portion 1623 is caused to collide with the second abutting surface 1612 during the movement to emit an audible sound or provide a downward connection to the splicing block 161. The thrust FD, at this time, the elastic body 162 releases the upward thrust FU to the abutting block 161, and even the downward thrust FD cancels a part of the upward restoring force FR, and reduces the keycap 13 from the high position HP toward the low position LP. The pressing force required to move.

如此，使用者可以在上述兩階段的移動過程中，感受到反饋按壓的按壓聲響，且感受到按壓力在彈性抵觸部1623經過抵觸交界點1613時瞬間由大變小，而產生的按壓段落手感，故，第一實施例的按鍵結構在操作時能夠提供類似機械軸開關按壓時的按壓聲響或較強烈明確觸覺的按壓段落手感。In this way, the user can feel the pressing sound of the feedback pressing during the above two-stage movement, and feel the pressure of the pressing section when the elastic abutting portion 1623 passes through the contact boundary point 1613. Therefore, the key structure of the first embodiment can provide a pressing sound when the mechanical shaft switch is pressed or a pressing stroke feeling that is more strongly and clearly tactile.

再者，應說明的是，底板模組12係對電路板11提供支撐，如圖1至圖2所示，底板模組12具有上方支撐板121、下方支撐板122、卡合結構123與彈性體設置機構124。上方支撐板121係設置於電路板11的上方以提供支撐，下方支撐板122係設置於電路板11的下方以提供支撐。卡合結構123係用於卡合剪刀腳結構14的下端，而對剪刀腳結構14提供定位。彈性體設置機構124係用於將彈性體162設置於底板模組12。於本發明中，可選擇性地，上方支撐板121和下方支撐板122可分別透過沖壓方式摺出卡合結構123與彈性體設置機構124，以避免形成卡合結構125與彈性體設置機構124所造成的破壞集中設置於上方支撐板121和下方支撐板122之其中ㄧ者，而使上方支撐板121和下方支撐板122兩者均能保留足夠的板材來對電路板11提供支撐。但不以此為限，若形成卡合結構123與彈性體設置機構124對上方支撐板121或下方支撐板122所造成的破壞不大，即便卡合結構125與彈性體設置機構124集中設置於單一個支撐板，也不會使所設置的支撐板的板材不足以支撐電路板11，如此，底板模組12也可僅設置上方支撐板121和下方支撐板122之其中ㄧ者，來對電路板11提供適當強度的支撐。Furthermore, it should be noted that the bottom plate module 12 provides support for the circuit board 11. As shown in FIG. 1 to FIG. 2, the bottom plate module 12 has an upper support plate 121, a lower support plate 122, an engaging structure 123 and elasticity. Body setting mechanism 124. The upper support plate 121 is disposed above the circuit board 11 to provide support, and the lower support plate 122 is disposed below the circuit board 11 to provide support. The snap-fit structure 123 is used to engage the lower end of the scissor-foot structure 14 while providing positioning for the scissor-foot structure 14. The elastic body setting mechanism 124 is for arranging the elastic body 162 on the bottom plate module 12. In the present invention, the upper support plate 121 and the lower support plate 122 can be respectively folded out of the engaging structure 123 and the elastic body setting mechanism 124 by punching to avoid forming the engaging structure 125 and the elastic body setting mechanism 124. The resulting damage is concentrated on the upper support plate 121 and the lower support plate 122, so that both the upper support plate 121 and the lower support plate 122 can retain sufficient plates to support the circuit board 11. However, not limited thereto, if the engaging structure 123 and the elastic body setting mechanism 124 are not damaged to the upper support plate 121 or the lower support plate 122, even if the engaging structure 125 and the elastic body setting mechanism 124 are collectively disposed on The single support plate does not make the plate of the support plate provided insufficient to support the circuit board 11. Thus, the bottom plate module 12 can also be disposed only by the upper support plate 121 and the lower support plate 122 to the circuit. Plate 11 provides support of appropriate strength.

第二實施例：Second embodiment:

In the second embodiment, the sliding surface 1632 is located on a surface of the sounding seat body 1633, and the restricting portion 1634 is disposed on the sounding seat body 1633 to limit the degree of elastic deformation of the elastic body 162. The elastic body 162 is a torsion spring embedded in the sounding seat body 1633, and the torsion spring has a sliding portion 1621, an elastic portion 1622, and an elastic abutting portion 1623. The elastic portion 1622 is received in the accommodating space 1631 of the sounding seat 163 for providing an elastic restoring force after the elastic deformation, and the sliding portion 1621 is located at the tail end of the elastic body 162 and extends to the lower surface of the restricting portion 1634 and Sliding surface between 1633.

於第二實施例中，當鍵帽13受到按壓而由高位置HP朝向低位置LP移動時，可至少包含以下兩階段的移動過程：In the second embodiment, when the keycap 13 is pressed to move from the high position HP toward the low position LP, the following two stages of the movement process may be included:

(a)如圖6-1-1至圖6-2-2所示，鍵帽13受到按壓會使抵接塊161抵觸彈性體162，如此，抵接塊161係可推抵彈性抵觸部1623而使彈性部1622彈性變形，使彈性抵觸部1623向右沿著第一抵觸面1611移動而到達抵觸交界點1613，以令滑動部1621接觸滑動表面1632並沿著滑動表面1632滑動，甚至使滑動部1621在滑動表面1632上滑動的過程中碰撞第一抵觸面1611，以發出聲響或對扺接塊161提供向上推力FU，此時，向上推力FU會與向上回復力源15的向上回復力FR協同，而增加鍵帽13由高位置HP朝向低位置LP移動所需施加的按壓力。另應說明的是，彈性抵觸部1623向右沿著第一抵觸面1611朝抵觸交界點1613移動時，彈性抵觸部1623會逐漸離開限制部1634的下表面，導致此時限制部1634無法對彈性體162的彈性變形給予限制。(a) As shown in FIG. 6-1-1 to FIG. 6-2-2, the key cap 13 is pressed to cause the abutting block 161 to abut against the elastic body 162. Thus, the abutting block 161 can be pushed against the elastic abutting portion 1623. The elastic portion 1622 is elastically deformed, so that the elastic abutting portion 1623 moves rightward along the first abutting surface 1611 to reach the contact boundary point 1613, so that the sliding portion 1621 contacts the sliding surface 1632 and slides along the sliding surface 1632, even sliding. The portion 1621 collides with the first abutting surface 1611 during sliding on the sliding surface 1632 to emit an audible sound or provide an upward thrust FU to the splicing block 161. At this time, the upward thrust FU and the upward restoring force FR of the upward returning force source 15 In synergy, the pressing force required to move the keycap 13 from the high position HP toward the low position LP is increased. It should be noted that when the elastic abutting portion 1623 moves to the right along the first abutting surface 1611 toward the contact boundary point 1613, the elastic abutting portion 1623 gradually leaves the lower surface of the restricting portion 1634, so that the restricting portion 1634 cannot be elastic at this time. The elastic deformation of the body 162 is limited.

(b) 如圖6-3-1至圖6-4-2所示，鍵帽13受到按壓會使抵接塊161抵觸彈性體162，如此，抵接塊161係可推抵彈性抵觸部1623而使彈性部1622彈性變形，以令彈性抵觸部1623由抵觸交界點1613向左沿著第二抵觸面1612移動，甚至使彈性抵觸部1623碰撞第二抵觸面1612，或者使彈性抵觸部1623接近或碰撞限制部1634的下表面，以發出聲響或對扺接塊161提供向下推力FD，此時，彈性體162會解除對抵接塊161提供向上推力FU，甚至，向下推力FD會抵銷向上回復力FR的一部分，而減少鍵帽13由高位置HP朝向低位置LP移動所需施加的按壓力。(b) As shown in FIGS. 6-3-1 to 6-4-2, the key cap 13 is pressed to cause the abutting block 161 to abut against the elastic body 162. Thus, the abutting block 161 can be pushed against the elastic abutting portion 1623. The elastic portion 1622 is elastically deformed so that the elastic abutting portion 1623 moves to the left along the second abutting surface 1612 from the abutting interface 1613, and even the elastic abutting portion 1623 collides with the second abutting surface 1612, or the elastic abutting portion 1623 is brought close to Or the lower surface of the collision limiting portion 1634 to emit an audible sound or provide a downward thrust FD to the splicing block 161. At this time, the elastic body 162 releases the upward thrust FU to the abutting block 161, and even the downward thrust FD may be offset. The pin restores a portion of the force FR upward, and reduces the pressing force required to move the keycap 13 from the high position HP toward the low position LP.

如此，使用者可以在上述兩階段的移動過程中，感受到反饋按壓的按壓聲響，且感受到按壓力在彈性抵觸部1623經過抵觸交界點1613時瞬間由大變小，而產生的按壓段落手感，故，第二實施例的按鍵結構在操作時能夠提供類似機械軸開關按壓時的按壓聲響或較強烈明確觸覺的按壓段落手感。In this way, the user can feel the pressing sound of the feedback pressing during the above two-stage movement, and feel the pressure of the pressing section when the elastic abutting portion 1623 passes through the contact boundary point 1613. Therefore, the key structure of the second embodiment can provide a pressing sound when the mechanical shaft switch is pressed or a pressing stroke feeling that is more strongly and clearly tactile when operating.

再者，應說明的是，當鍵帽13受到的按壓解除後，彈性部1622係可對滑動部1621提供彈性回復力，使滑動部1621依序沿著第二抵觸面1612、抵觸交界點1613與第一抵觸面1611而返回初始位置，以等待下一次抵接塊161推抵彈性抵觸部1623，即等待鍵帽13受到的下一次按壓。In addition, it should be noted that, after the pressing of the key cap 13 is released, the elastic portion 1622 can provide an elastic restoring force to the sliding portion 1621, so that the sliding portion 1621 sequentially passes along the second abutting surface 1612 and the interface point 1613. Returning to the initial position with the first abutting surface 1611, waiting for the next abutment block 161 to push against the elastic abutting portion 1623, that is, waiting for the next pressing of the key cap 13.

第三實施例：Third embodiment:

請一併參考圖7至圖10，其中，如左列所參考的各圖所示，第三實施例與第二實施例最大的差異在於，第三實施例的抵接塊161係一體成形於內支臂141而非設置於鍵帽13上。於本實施例中，抵接塊161係自內支臂141的側表面而延伸至內支臂開口1411內，且抵接塊161與彈性體162於內支臂開口1411沿著抵接塊移動路徑的投影係部分重疊，使抵接塊161在移動過程中能夠抵觸彈性體162。Please refer to FIG. 7 to FIG. 10 together, wherein, as shown in the figures referred to in the left column, the greatest difference between the third embodiment and the second embodiment is that the abutting block 161 of the third embodiment is integrally formed. The inner arm 141 is not disposed on the keycap 13. In the present embodiment, the abutting block 161 extends from the side surface of the inner arm 141 into the inner arm opening 1411, and the abutting block 161 and the elastic body 162 move along the abutting block at the inner arm opening 1411. The projections of the paths partially overlap such that the abutment block 161 can interfere with the elastomer 162 during movement.

當鍵帽13由高位置HP朝向低位置LP移動時，抵接塊161係可隨著鍵帽13的移動，在內支臂141上沿著抵接塊移動路徑移動，而彈性體162係位於抵接塊移動路徑中，使抵接塊161在移動過程中能夠如圖10所示抵觸彈性體162的彈性抵觸部1623，以令滑動部1621接觸滑動表面1632並沿著滑動表面1632滑動而發出聲響，或者，使鍵帽13的按壓力在彈性抵觸部1623經過抵觸交界點1613時瞬間由大變小，而產生按壓段落手感。關於所述發出聲響或產生段落按壓手感的方式與第二實施例大致相同，於此不再贅述。When the keycap 13 is moved from the high position HP toward the low position LP, the abutting block 161 is movable along the abutting block moving path on the inner arm 141 as the key cap 13 moves, and the elastic body 162 is located. In the abutting block moving path, the abutting block 161 can be in contact with the elastic abutting portion 1623 of the elastic body 162 as shown in FIG. 10 to make the sliding portion 1621 contact the sliding surface 1632 and slide along the sliding surface 1632. The sound is sounded, or the pressing force of the keycap 13 is instantaneously changed from large to small when the elastic abutting portion 1623 passes the contact boundary point 1613, and the pressing portion feel is generated. The manner in which the sound is generated or the feel of the paragraph is pressed is substantially the same as that of the second embodiment, and details are not described herein again.

第四實施例：Fourth embodiment:

請一併參考圖11至圖14，其中，如左列所參考的各圖所示，第四實施例與第三實施例最大的差異在於，第四實施例的彈性體162係為板片彈片，所述板片彈片係沿著實質正交於抵接塊移動路徑的方向延伸，彈性抵觸部1623係浮凸於板片彈片靠近抵接塊161的一側。當鍵帽13由高位置HP朝向低位置LP移動時，抵接塊161係可隨著鍵帽13的移動，在內支臂141上沿著抵接塊抵接塊移動路徑移動，使抵接塊161的第一抵觸面1611能夠抵觸彈性抵觸部1623，俾令板片彈片能夠受到抵接塊161的抵觸而彈性變形，以在抵接塊161與彈性體162之間發出聲響或產生按壓手感。Referring to FIG. 11 to FIG. 14 together, the maximum difference between the fourth embodiment and the third embodiment is that the elastic body 162 of the fourth embodiment is a plate shrapnel as shown in the drawings referred to in the left column. The elastic piece of the plate extends in a direction substantially orthogonal to the moving path of the abutting block, and the elastic abutting portion 1623 is embossed on a side of the elastic piece of the plate near the abutting block 161. When the keycap 13 is moved from the high position HP toward the low position LP, the abutting block 161 can move along the abutting block abutment block moving path on the inner arm 141 as the keycap 13 moves, so that the abutment The first abutting surface 1611 of the block 161 can resist the elastic abutting portion 1623, so that the elastic piece of the plate can be elastically deformed by the abutting of the abutting block 161 to make a sound or a pressing feeling between the abutting block 161 and the elastic body 162. .

第五實施例：Fifth embodiment:

請一併參考圖15至圖18，其中，如左列所參考的各圖所示，第五實施例與第四實施例最大的差異在於，第四實施例的彈性體162係為氣室腔體，所述氣室腔體係具有例如為孔狀結構的揚聲結構1625，且於初始狀態時氣室腔體內部收容有發聲氣體G。彈性抵觸部1623係浮凸於氣室腔體靠近抵接塊161的一側。當鍵帽13由高位置HP朝向低位置LP移動時，抵接塊161的第一抵觸面1611能夠抵觸彈性體162的彈性抵觸部1623，使得氣室腔體受到抵接塊161的抵觸而彈性變形，讓發聲氣體G經由揚聲結構1625逐漸流出氣室腔體而發出聲響。如圖16-1所示，當鍵帽13由低位置LP朝向高位置HP移動時，第一抵觸面1611係離開彈性抵觸部1623，使得氣室腔體能夠不受到抵接塊161的抵觸，而逐漸回復初始狀態於內部收容發聲氣體G，以等待下一次抵接塊161推抵彈性抵觸部1623，即等待鍵帽13受到的下一次按壓。Referring to FIG. 15 to FIG. 18 together, the maximum difference between the fifth embodiment and the fourth embodiment is that the elastic body 162 of the fourth embodiment is a gas chamber cavity, as shown in the drawings referred to in the left column. The air chamber system has a speaker structure 1625 having a hole-like structure, and the sounding gas G is accommodated inside the air chamber chamber in an initial state. The elastic abutting portion 1623 is embossed on a side of the air chamber cavity adjacent to the abutting block 161. When the key cap 13 is moved from the high position HP toward the low position LP, the first abutting surface 1611 of the abutting block 161 can abut against the elastic abutting portion 1623 of the elastic body 162, so that the air chamber cavity is elastically resisted by the abutting block 161. The deformation causes the audible gas G to gradually exit the air chamber cavity via the speaker structure 1625 to make an audible sound. As shown in FIG. 16-1, when the keycap 13 is moved from the low position LP toward the high position HP, the first abutting surface 1611 is separated from the elastic abutting portion 1623 so that the air chamber cavity can be prevented from being abutted by the abutting block 161. On the other hand, the initial state is gradually returned to the inside to receive the sounding gas G, waiting for the next abutment block 161 to push against the elastic abutting portion 1623, that is, waiting for the next pressing of the keycap 13.
