Abstract

The invention discloses a vibration keyboard. The vibration keyboard includes a vibrator and a keyswitch mechanism. The vibrator includes two parallel plates disposed oppositely, an expanding and shrinking device connected to and between the two plates, and two magnetic parts fixedly connected to the two plates respectively. The expanding and shrinking device can be driven by an electronic single to expand or shrink, so as to produce vibration. A magnetic attraction force is induced between the two magnetic parts. The magnetic attraction force is capable of urging the two plates to move back to their original relative position. The keyswitch mechanism contacts the vibrator such that the vibration produced by the vibrator can be transferred to the keyswitch mechanism, so as to provide a sensible operation feedback for a user.

Description

Vibrating keyboard

The invention relates to a vibrating keyboard, in particular to a vibrating keyboard for providing horizontal vibration.

The traditional button mechanism is relatively large, and can provide a large installation space. When the user uses the device, the stroke can be directly pressed through the finger to feel whether the pressing operation is completed. With the trend of thinning the keyboard, the height of the keyboard is significantly reduced. The traditional mechanical button mechanism with a large pressing stroke has been difficult to apply. Therefore, the thin keyboard currently adopts the design of a small stroke button or a touch button. However, it is difficult for the user to feel the pressing feedback regardless of the button of the small stroke or the touch button, which may cause the user to be unable to confirm whether the pressing operation is completed during the actual use, which causes many operational troubles. At present, although a vibrator (such as an eccentric motor) is added to the keyboard to generate vibration, thereby providing an additional keyboard for the user to press back, but limited by the volume of the vibrator, this design cannot be used in a thin keyboard. Therefore, how to provide a press feedback that the user can effectively feel in the thin keyboard is one of the problems faced by the thin keyboard.

In view of the problems in the prior art, it is an object of the present invention to provide a vibrating keyboard that utilizes a flat vibrator to provide operational feedback that a user can perceive.

The vibrating keyboard of the present invention comprises a vibrator and a button mechanism. The vibrator comprises a first plate member, a second plate member, an extension and contraction member, a first magnetic member and a second magnetic member. The second plate member is disposed in parallel with the first plate member. The stretching and contracting member is disposed between the first plate member and the second plate member, the extension and contraction member has a first connecting portion and a second connecting portion, and the stretching and contracting member is fixedly connected to the first connecting portion via the first connecting portion The first plate member is fixedly coupled to the second plate member via the second connecting portion. When the stretching and contraction element is driven by a signal The stretching and contracting member expands or contracts to output a telescopic force that causes a relative movement between the first plate member and the second plate member. The first magnetic member is fixedly coupled to the first plate member, the second magnetic member is fixedly coupled to the second plate member and adjacent to the first magnetic member, and a magnetic member and the second magnetic member are coupled to each other A magnetic attraction. The button mechanism has a bottom portion that is in contact with the first plate member to transmit vibration generated by the relative movement to the bottom portion. Wherein, when the electrical signal disappears, the stretching and contracting member has an original length, according to the original length, maintaining an original relative position between the first plate member and the second plate member; when the stretching and contracting member is telecommunication When the driving force is deformed to output the telescopic force, the relative movement between the first plate member and the second plate member is generated away from the original relative position; when the electrical signal disappears, the first magnetic force drives the first plate And moving the second plate toward the original relative position. Thereby, through the stretching and contracting element, the vibrator can generate vibration to provide an operational feedback that the user can feel. In addition, the vibrator is in the form of a flat plate, so the design of the vibrating keyboard of the present invention is quite suitable for a thin keyboard.

As shown in the three dashed blocks in FIG. 1, the vibrating keyboard 1 includes three side-by-side vibrators 12 each vibrating a button in a dashed block, a button mechanism 14, a controller 16, and a casing 18. The vibrator 12, the button mechanism 14 and the controller 16 are housed in the outer casing 18, the vibrators 12 are arranged side by side, the button mechanism 14 is stacked on the vibrator 12, and the controller 16 is electrically connected to the vibrator 12; among them, three vibrations The controller 12 and the controller 16 respectively indicate their positions in the first drawing in a dashed box. When the controller 16 transmits the electrical signal 162 to the vibrator 12, the vibrator 12 can be driven to generate a shock that can be transmitted to the button mechanism 14 and can be perceived by the user via the button mechanism 14. In the present embodiment, the vibrating keyboard 1 cooperates with the size of the button mechanism 14 to use three vibrators 12 to be connected into a larger vibrator to provide a relatively uniform source of vibration with respect to the button mechanism 14, or to selectively vibrate each. However, the invention is not limited thereto. For example, only one or two vibrators 12 are used, or a larger vibrator is used directly.

Further, please refer to FIGS. 3 to 5, FIG. 4 is a plan view of the vibrator 12, and FIG. 5 is a cross-sectional view of the vibrator 12 along the line Y-Y of FIG. 4. The vibrator 12 includes a first plate member 122, a second plate member 124, three extension and contraction members 126, and four sets of magnetic members 128a-128d and 129a-129d. The second plate member 124 is disposed in parallel with the first plate member 122. The stretching and contracting member 126 is disposed between the first plate member 122 and the second plate member 124. The stretch-contraction element 126 has a first connecting portion 1262 and a second connecting portion 1264. For simplicity of the drawing, the single stretch-contracting member 126 is indicated by a dashed box. The extension and contraction element 126 is fixedly coupled to the first plate member 122 via the first connection portion 1262 , and the extension and contraction member 126 is fixedly coupled to the second plate member 124 via the second connection portion 1264 . The stretching and contracting member 126 can be driven to produce an expansion or contraction to output a telescopic force that causes a relative movement between the first panel 122 and the second panel 124.

In the present embodiment, the stretching and contraction member 126 is provided by Artificial Muscle. Reflex(TM) X-Mode Actuator 1-phase bar is implemented by electroactive polymer vibration element comprising an electroactive polymer (EAP) as shown in Fig. 6; but the invention None of them is limited to this. In Fig. 6, the electroactive polymer vibration element 127 comprises a frame 1272, three output discs 1274, and three EAP films 1276 between the frame 1272 and the three output discs 1274 (the exposed portions of which are indicated by hatching) The upper and lower surfaces of the EAP film 1276 are covered with a conductive layer as an electrode for generating an electric field. When the electroactive polymer vibrating element 127 is driven, the three EAP films 1276 are simultaneously stretched or contracted such that the output disc 1274 is movable relative to the frame 1272. Therefore, in the present embodiment, the stretch-contraction deformation portion is formed in the stretching and contraction member 126 as an electroactive polymer film 1266, and the first connecting portion 1262 and the second connecting portion 1264 are connected. When the electroactive polymer film 1266 is affected by the electric field, it will contract in the direction of the parallel electric field (i.e., parallel to the Z-axis direction) such that the vertical electric field direction (i.e., the vertical Z-axis direction) expands. The amount of deformation of the electroactive polymer film 1266 is in principle proportional to the electric field strength. As shown in FIG. 6, based on the embodiment, the electroactive polymer vibration element 127 is used as the structure of the extension and contraction element 126, and the frame 1272 is fixedly coupled to the first plate member 122 corresponding to the first connection portion 1262, and the output plate is output. 1274 is fixedly connected to the second plate member 124 corresponding to the second connecting portion 1264. When the electroactive polymer vibration element 127 is driven, the relative movement between the frame 1272 and the three output disks 1274 can be generated, thereby making the first plate The relative movement between the member 122 and the second plate member 124 is parallel to an X-axis direction.

The magnetic members 128a-128d are fixedly connected to the first plate member 122, and the magnetic members 129a-129d are correspondingly fixedly connected to the second plate member 124 and disposed adjacent to the corresponding magnetic members 128a-128d, so that each set of magnetic members 128a and 129a, A magnetic attraction is generated between 128b and 129b, 128c and 129c, 128d and 129d. When the stretching and contracting member 126 is not driven, the magnetic attraction generated between the magnetic members 128a to 128d, 129a to 129d is stably balanced, so that the first plate member 122 and the second plate member 124 are maintained in an original relative position; When the contracting element 126 is driven, the magnetic attraction generated between the magnetic members 128a-128d, 129a-129d can drive the first plate member 122 and the second plate member 124 to revert to the original relative position, and the magnetic attraction force is also indirectly transmitted through the first plate. The piece 122 and the second plate 124 drive the stretch-contraction element 126 back to its original state (ie, the undeformed state). In this embodiment, four The set of magnetic members 128a-128d and 129a-129d are symmetrically disposed on the opposite sides of the stretching and contracting member 126 or on opposite sides of the stretching and contracting member 126, and the magnetic attraction generated by each group is symmetrical with respect to the stretching and contracting member 126, which contributes to the vibrator 12 The actuated stability includes the stability of the relative motion between the first plate member 122 and the second plate member 124 and the stability of the extension and contraction member 126. In addition, in the embodiment, the magnetic members 128a-128d, 129a-129d also serve as spacers between the first plate member 122 and the second plate member 124, so that the first plate member 122 and the second plate member 124 are The space can be formed to accommodate the extension and contraction member 126 so that the extension and contraction member 126 can normally expand or contract, but the invention is not limited thereto. For example, a spacer ring is provided to provide a spacing effect, or one or more grooves are formed on the first plate member 122 and the second plate member 124 to accommodate the magnetic members 128a-128d, 129a-129d and the stretching and contracting members, respectively. 126, the first plate member 122 and the second plate member 124 are directly slidably in contact with each other. In addition, in the embodiment, the first plate member 122 and the second plate member 124 are sized and rectangular, and the four sets of magnetic members 128a-128d and 129a-129d are disposed substantially at the four corners of the rectangle to facilitate vibration. The overall structure of the device 12 is stable, but the invention is not limited thereto.

The button mechanism 14 includes a light guide plate 142, a thin film circuit board 144 and a soft pad 146. The light guide plate 142 is disposed on the first plate member 122. The thin film circuit board 144 is electrically connected to the controller 16 and stacked on the light guide plate 142. The cushion 146 is then stacked on the film circuit board 144. Thereby, the bottom portion 14a of the button mechanism 14 (ie, the lower surface of the light guide plate 142) contacts the first plate member 122 such that the vibration generated by the relative movement between the first plate member 122 and the second plate member 124 can be transmitted to the bottom portion 14a. It can be perceived by the user. In practice, the light guide plate 142 is adhered to the first plate member 122, which can increase the effect of vibration transmission. The thin film circuit board 144 has a plurality of thin film circuit board switches 1442 covering the plurality of thin film circuit board switches 1442 and having a plurality of protruding key cap bumps 1462 respectively corresponding to the plurality of thin film circuit board switches 1442. . The pad 146 defines a protrusion 1464 on the lower surface of the corresponding key cap bump 1462 so that when the user presses the key cap bump 1462, the corresponding protrusion 1464 can trigger the corresponding thin film circuit board switch 1442 (or The membrane circuit board switch 1442) is turned on to achieve the function of the key input, and the controller 16 provides the electrical signal 162 to drive the stretching and contracting element 126 to expand or contract. The outer casing 18 includes an outer side wall 182 and an outer bottom shell 184. The upper end of the outer side wall 182 has a protruding portion 1822. The button mechanism 14 is disposed between the protruding portion 1822 and the outer bottom case 184, and the key cap bump 1462 is exposed to the outer casing 18.

Please refer to FIG. 4 and FIG. 7 , FIG. 4 is a plan view of the vibrator 12 when it is not vibrated, and FIG. 7 is a plan view of the vibrator 12 at the maximum vibration distance, wherein the maximum vibration distance of the vibrator 12 is exaggerated. For ease of explanation. When the vibrator 12 is not vibrating (for example, when the electric signal 162 disappears), the stretching and contracting member 126 has an original length L1; at this time, the first plate member 122 and the second plate member 124 are kept in original relative position according to the original length L1. The location is as shown in Figure 4. When the stretching and contracting member 126 is driven by the electrical signal 162, the stretching and contracting member 126 expands or contracts to output a telescopic force that causes a relative movement between the first plate member 122 and the second plate member 124 parallel to the X-axis direction. In other words, when the stretching and contracting member 126 is driven by the electrical signal 162 to deform the output telescopic force, the first plate member 122 and the second plate member 124 are moved relative to each other away from the original relative position. When the stretching and contracting member 126 reaches the maximum extended state, it has a maximum length L2, and the difference between the maximum length L2 and the original length L1 is the maximum vibration distance, as shown in FIG. Once the relative displacement between the first plate member 122 and the second plate member 124 occurs, the magnetic attraction generated between the magnetic members 128a-128d and 129a-129d can drive the first plate member 122 and the second plate member 124 to revert to the original relative position. Position, so when the electrical signal 162 disappears, the magnetic attraction drives the first plate member 122 and the second plate member 124 to move toward the original relative position. At the same time, the magnetic attraction force also indirectly passes through the first plate member 122 and the second plate member. 124 drives the stretch-contraction element 126 back to its original state (ie, the undeformed state). In practice, the controller 16 periodically provides an electrical signal 162 to drive the extensional contraction element 126 such that the extensional contraction element 126 is periodically moved. For example, the user presses a keycap bump 1462 to trigger the corresponding thin film circuit board switch 1442 for a period of time during which time the controller 16 periodically provides an electrical signal 162 to drive the stretching and contraction element 126.

Please refer to Figures 4 and 5. In the present embodiment, the magnetic members 128a-128d, 129a-129d are located between the first plate member 122 and the second plate member 124. As shown in FIG. 5, the magnetic members 128a and 128d have a sliding surface. 1282a, 1282d and below sliding surfaces 1282a, 1282d slidingly contact the second plate member 124; the magnetic members 129a, 129d have an upper sliding surface 1292a, 1292d The sliding surfaces 1292a and 1292d are in sliding contact with the first plate member 122. At this time, the distance between the first plate member 122 and the second plate member 124 is affected by the heights of the magnetic members 128a to 128d, 129a to 129d. In addition, taking one of the magnetic members 128d, 129d as an example, the magnetic member 128d has a left sliding surface 1284d, the corresponding magnetic member 129d has a right sliding surface 1294d, and the left sliding surface 1284d slidingly contacts the right sliding surface 1294d, the left sliding surface 1284d and the right sliding surface 1294d are parallel to the relative movement direction (ie, the X-axis direction); the other sets of magnetic members 128a-128c and 129a-129c are the same, and are not described again. The magnetic members 129a-129d are disposed between the magnetic members 128a-128d, so that the magnetic members 128a-128d, 129a-129d also have a restraining effect on the relative movement of the first plate member 122 and the second plate member 124, so that the first The relative movement of the plate member 122 and the second plate member 124 and the expansion and contraction member 126 are stably stabilized, thereby enabling the vibrator 12 to be stably operated. In addition, referring to FIG. 7, the relative motion generated between the first plate member 122 and the second plate member 124 has a relative movement distance L3. When the extension and contraction member 126 reaches the maximum vibration distance, the relative movement distance L3 also has the maximum. value. The left sliding surface 1284d and the right sliding surface 1294d have a contact length L4 when the stretching and contracting member 126 is not vibrated. The contact length L4 is greater than the relative movement distance L3 (even if the relative movement distance L3 reaches a maximum value), so that the vibrator 12 vibrates. During the process, the left sliding surface 1284d and the right sliding surface 1294d can maintain the contact state, which also contributes to the stability of the relative movement of the first plate member 122 and the second plate member 124.

In principle, the magnetic attraction generated between the respective sets of magnetic members 128a to 128d and 129a to 129d is obtained by the arrangement of the magnetic poles. In the embodiment of the present invention, as shown in FIG. 4 and FIG. 7, the relative movement direction between the first plate member 122 and the second plate member 124 is along the X axis, and the magnetic members 128a to 128d and 129a to 129d. The magnetic pole polarity is directly indicated in the figure by the magnetic pole symbol for convenience of explanation. A Y-axis is perpendicular to the X-axis, and the first plate member 122 and the second plate member 124 are disposed parallel to the X-axis and the Y-axis, and a Z-axis is perpendicular to the X-axis and the Y-axis. The magnetic members 128a to 128d have a magnetic N pole in the positive direction of the Y axis and a magnetic S pole in the negative direction of the Y axis. Similarly, the magnetic members 129a to 129d have a magnetic N pole in the positive direction of the Y axis, and the Y axis The negative direction has a magnetic S pole. When a disassembly motion is generated between the first plate member 122 and the second plate member 124 along the Y-axis or the Z-axis, the magnetic attraction generated between the respective sets of magnetic members 128a-128d and 129a-129d will oppose the disassembly movement. , the first plate 122 and the second plate 124 are kept in combination together. In addition, in this embodiment, the structural arrangement of the magnetic members 128a-128d, 129a-129d itself prevents the first plate member 122 and the second plate member 124 from being disassembled along the Y-axis (or Relative motion), but in other practical applications, the structural arrangement of the magnetic members 128a-128d, 129a-129d may not prevent the first plate member 122 and the second plate member 124 from being disassembled along the Y-axis. When the aforementioned magnetic attraction force is effective against the effect of the disassembly motion.

Please refer to FIG. 8, which is a cross-sectional view of the vibrator 22 according to another embodiment, and the cross-sectional position thereof can be referred to the fourth line Y-Y. The vibrator 22 is substantially identical in construction to the vibrator 12, so in the eighth diagram, the vibrator 22 in principle still uses the component symbols of the vibrator 12. The vibrator 22 is mainly different from the vibrator 12 in that the magnetic members 228a, 228d have a magnetic N pole in the positive direction of the Z axis and a magnetic S pole in the negative direction of the Z axis; oppositely, the magnetic members 229a, 229d are on the X axis. The positive direction has a magnetic S pole and a magnetic N pole in the negative direction of the X axis. The magnetic pole polarities of the magnetic members 228a, 228d, 229a, and 229d are directly indicated by magnetic pole symbols in the drawings for convenience of explanation. Similarly, the magnetic attraction generated between the sets of magnetic members 228a, 228d and 229a, 229d can drive the first plate member 122 and the second plate member 124 toward the original relative position. In addition, when a disassembly movement along the Y-axis or the Z-axis occurs between the first plate member 122 and the second plate member 124, the magnetic attraction generated between the respective sets of the magnetic members 228a, 228d and 229a, 229d opposes the disassembly. The motion is removed such that the first panel 122 and the second panel 124 remain bonded together. For other descriptions of the vibrator 22, refer to the related description of the vibrator 12, and no further details are provided.

In the foregoing embodiments, the magnetic members 128a-128d, 129a-129d, 228a, 228d, 229a, and 229d are in contact with the first plate member 122 and the second plate member 12, but the invention is not limited thereto. Referring to FIG. 9 and FIG. 10, FIG. 9 is a plan view of a vibrator 32 according to another embodiment, and FIG. 10 is a cross-sectional view of the vibrator 32 along line ZZ of FIG. 9, wherein in FIG. The stretch-contraction element 126 is shown as a single dashed box, and in Figure 10, only a single stretch-contraction element 126 is shown to simplify the drawing. The vibrator 32 is substantially identical in construction to the vibrator 12, so in the FIGS. 9 and 10, the vibrator 32 in principle still uses the component symbols of the vibrator 12. The vibrator 32 differs from the vibrator 12 mainly in that each set of magnetic members 328a-328d and 329a, 329d (the other two are not shown) In the figure, the magnetic member 328d and the magnetic member 329d are disposed between the first plate member 122 and the second plate member 124, and magnetically The member 328d has a lower sliding surface 3282d, the magnetic member 329d has an upper sliding surface 3292d, the lower sliding surface 3282d slidingly contacts the upper sliding surface 3292d, and the lower sliding surface 3282d and the upper sliding surface 3292d are parallel to the relative moving direction (ie, parallel to the X). axis). The magnetic members 328a to 328d have a magnetic N pole in the positive direction of the Z axis and a magnetic S pole in the negative direction of the Z axis. Similarly, the magnetic members 329a and 329d have a magnetic N pole in the positive direction of the Z axis, and the Z axis The negative direction has a magnetic S pole. The polarity of the magnetic poles of the magnetic members 328c, 328d, 329c, and 329d is directly indicated by the magnetic pole symbol in FIG. 10 for convenience of explanation. Similarly, the magnetic attraction generated between the sets of magnetic members 328a-328d and 329a, 329d (the other two are not shown) can drive the first plate member 122 and the second plate member 124 to move toward the original relative position. In addition, when a disassembly movement along the Y-axis or the Z-axis occurs between the first plate member 122 and the second plate member 124, each set of magnetic members 328a-328d and 329a, 329d (the other two are not shown in the figure). The magnetic attraction generated between the two will resist the disassembly motion, so that the first plate member 122 and the second plate member 124 remain bonded together. For other descriptions of the vibrator 32, refer to the related description of the vibrator 12, and no further details are provided.

Referring to Fig. 11, which is a cross-sectional view of a vibrator 42 according to another embodiment, the cross-sectional position can be referred to the ninth line Z-Z, and only a single stretch-contraction member 126 is shown to simplify the drawing. The vibrator 42 and the vibrator 32 are substantially identical in construction, so in the eleventh diagram, the vibrator 42 in principle still uses the component symbols of the vibrator 32. The vibrator 42 is mainly different from the vibrator 32 in that the magnetic members 428c, 428d, 429c, 429d (the other two sets of magnetic members are not shown in the drawing) are disposed unevenly between the first plate member 122 and the second plate member 124. In this embodiment, the magnetic members 428c, 428d are fixedly coupled to the first plate member 122 with respect to the magnetic members 429c, 429d. In practice, when the vibrator 42 is combined with the button mechanism 14, the button mechanism 14 can be provided with an appropriate structure to be firmly coupled with the magnetic members 428c, 428d and the first plate member 122. This is a basic specification for those skilled in the art. The disclosure is easy and complete, and will not be repeated. Although the magnetic members 428c, 428d and 429c, 429d are spaced apart from the first plate member 122, in practice, only the magnetic force generated between the magnetic members 428c, 428d, 429c, and 429d is strong enough, and each group of magnetic members 428c, 428d and The magnetic attraction generated between 429c and 429d can still effectively drive the first plate 122 and The second plate 124 moves in the original relative position. In addition, when a disassembly movement along the Y-axis or the Z-axis occurs between the first plate member 122 and the second plate member 124, the magnetic attraction generated between the respective sets of magnetic members 428c, 428d and 429c, 429d will oppose the disassembly. The motion is removed such that the first panel 122 and the second panel 124 remain bonded together. For other descriptions of the vibrator 42, refer to the related description of the vibrator 32, and no further details are provided.

In addition, in the foregoing embodiments, the magnetic members are stacked or arranged side by side. Therefore, as long as the magnetic members are relatively displaced, the magnetic attraction generated between the sets of magnetic members can drive the respective sets of magnetic members to return to the original relative positions. Therefore, in the foregoing embodiments, the arrangement (including the number and the magnetic pole arrangement) of the magnetic member is a suitable example, and the outline of the magnetic member is a rectangle, which is only convenient for representation, and the invention is not limited thereto, and is used in practice. The required magnetic components (including shape, number and pole configuration) can be set according to actual product requirements.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
