  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  However, for convenience of explanation, the drawings to be referred to below show simplified main members necessary for explaining the present invention, among the constituent members of one embodiment of the present invention. Therefore, the vibration device and the electronic device according to the present invention can include arbitrary constituent members that are not shown in the drawings referred to in this specification.

  As shown in FIGS. 1 to 3, the vibration device X <b> 1 according to the present embodiment includes a liquid crystal panel 2, a touch panel 3, a vibration body 4, a support body 5, and an elastic member 6.

  The liquid crystal panel 2 includes a first substrate, a second substrate disposed opposite the first substrate, a liquid crystal layer interposed between the first substrate and the second substrate, and a display disposed between the first substrate and the second substrate. And a backlight for irradiating light to one substrate and the other substrate. Here, for convenience of explanation, illustration of each of the one substrate, the other substrate, the liquid crystal layer, the display member layer, and the backlight is omitted. Examples of the display member layer include a pixel electrode, an alignment film, and a color filter. The driving method of the liquid crystal panel 2 may be a simple matrix driving method or an active matrix driving method.

  Instead of the liquid crystal panel 2, a display panel such as a plasma panel, an organic EL panel, or electronic paper may be used. Here, the organic EL panel is a display panel using a substance that emits light when a voltage is applied. Specifically, the organic EL panel is displayed by depositing a light emitter using an organic substance such as diamine on a substrate and applying a DC voltage of 5 to 10V. In addition, when an organic EL panel is used instead of the liquid crystal panel 2, a backlight is not necessary.

  The touch panel (operation panel) 3 is an input device that detects a position operated by a user with a finger or a pen as an input position. The touch panel 3 has an input area E1 and a non-input area E2. The input area E1 is an area where the user can perform an input operation. In the present embodiment, the input area E <b> 1 is an area facing the liquid crystal panel 2 on the touch panel 3. The non-input area E2 is an area where the user cannot perform an input operation. In the present embodiment, the non-input area E <b> 2 is an area that does not face the liquid crystal panel 2 on the touch panel 3. In the present embodiment, the non-input area E2 is located outside the input area E1 so as to surround the input area E1, but is not limited thereto. For example, the non-input area E2 may be located in the input area E1.

Here, the input area E1 of the touch panel 3 is an embodiment of the “central portion of the operation panel” according to the present invention. The non-input area E2 of the touch panel 3 is an embodiment of the “end portion of the operation plate” according to the present invention.

  The touch panel 3 has an upper surface 3a, a lower surface 3b located on the opposite side of the upper surface 3a, and four end surfaces 3c adjacent to the upper surface 3a and the lower surface 3b. That is, the upper surface 3a of the touch panel 3 corresponding to the input area E1 is a surface directly operated by the user with a finger or a pen. As shown in FIGS. 2 and 3, the touch panel 3 is disposed to face the liquid crystal panel 2 via a space (hereinafter, the space is referred to as “internal space”) S <b> 1. As shown in FIG. 1, the touch panel 3 has a rectangular shape in plan view, but is not limited thereto, and the shape thereof is arbitrary.

  In the present embodiment, the touch panel 3 is a capacitive touch panel from the viewpoint of improving detection sensitivity. Further, from the viewpoint of thinning, among the capacitive touch panels, a cover glass integrated type is preferable. Note that instead of the capacitive touch panel, for example, a resistive touch panel, a surface acoustic wave touch panel, an infrared touch panel, or an electromagnetic induction touch panel may be used.

  In this specification, the touch panel 3 may include a protective member that protects the touch panel 3 or may include a protective member that does not include the protective member. When the touch panel 3 includes the protective member, the upper surface 3a of the touch panel 3 may mean the upper surface of the protective member, or the upper surface of the base body constituting the touch panel 3 without the protective member. It may mean. Further, the lower surface 3 b of the touch panel 3 may mean the lower surface of the base that constitutes the touch panel 3, or may mean the lower surface of the insulating film provided on the lower surface of the base that constitutes the touch panel 3.

  The vibrating body 4 has a role of bending and vibrating the touch panel 3 when a predetermined input operation by the user is detected. Specifically, the vibrating body 4 causes the touch panel 3 to bend and vibrate in the thickness direction of the touch panel 3 (hereinafter, this direction is referred to as “vertical direction”) by repeating expansion and contraction movement in the short side direction of the touch panel 3. . In addition, although mentioned later for details, the vibrating body 4 also has a role which detects the press load to the touch panel 3. FIG. The vibrating body 4 is provided on the lower surface 3b of the touch panel 3 corresponding to the non-input area E2.

  In the present embodiment, the vibrating body 4 is, for example, a piezoelectric element that performs expansion and contraction based on an applied voltage, but is not limited thereto. As the vibrating body 4, an electromagnetic vibrating body, a motor, or the like may be used instead of the piezoelectric element. Moreover, as a piezoelectric element, any of a monomorph, a unimorph, and a bimorph may be sufficient.

  In the present embodiment, as shown in FIG. 1, two vibrating bodies 4 are provided in the vicinity of both short sides of the touch panel 3 along each short side. In addition, the arrangement position, the number, and the like of the vibrating body 4 are not particularly limited. For example, two vibrating bodies 4 may be provided in the vicinity of both long sides of the touch panel 3 along each long side, or in the vicinity of both the long sides and short sides of the touch panel 3, respectively. Four may be provided along the long side and the short side.

  The support 5 has a role of supporting the liquid crystal panel 2 and a role of supporting the touch panel 3 via the elastic member 6. The support 5 has a main surface 5a. The liquid crystal panel 2 is provided on the main surface 5 a of the support 5. Examples of the constituent material of the support 5 include resins such as polycarbonate, metals such as stainless steel, aluminum, and magnesium alloys.

The elastic member 6 surrounds the input area E1 and is located in the non-input area E2 of the touch panel 3. That is, the elastic member 6 is provided in a frame shape along the long side and the short side of the touch panel 3. The elastic member 6 is connected to the lower surface 3 b of the touch panel 3 via a double-sided tape 71 and is connected to the main surface 5 a of the support 5 via a double-sided tape 72. Examples of the constituent material of the elastic member 6 include silicone rubber, urethane rubber, urethane foam, and other rubbers.

In addition, although the example which used the double-sided tapes 71 and 72 as a connection means which connects the elastic member 6 and the touch panel 3, and the elastic member 6 and the support body 5 was demonstrated, it is not restricted to this. Instead of the double-sided tapes 71 and 72, an adhesive means such as an acrylic resin adhesive, a urethane resin adhesive, an epoxy resin adhesive, or a silicone adhesive may be used.

  The elastic member 6 has a space S <b> 2 (hereinafter, the space is referred to as “hollow”) inside. For this reason, the elastic member 6 has the 1st side wall 6a and the 2nd side wall 6b located in the input area E1 side rather than the 1st side wall 6a. Here, FIG. 4 is an enlarged view of the portion A1 shown in FIG. As shown in FIG. 4, the thickness T1 of the second side wall 6b is smaller than the thickness T2 of the first side wall 6a.

  Since the thickness T1 of the second side wall 6b is smaller than the thickness T2 of the first side wall 6a, the elastic member 6 can follow the vibration of the touch panel 3 even if the touch panel 3 repeats bending vibration in the vertical direction. The possibility that the vibration of 3 is hindered can be reduced.

  Specifically, as shown in FIG. 5, when the touch panel 3 is bent downward (in the direction of the arrow in FIG. 5), the elastic member 6 is pushed downward by the touch panel 3, and the second side wall 6 b is Dent. That is, the second side wall 6 b is recessed following the downward curve of the touch panel 3. Thereby, compared with the case where the touch panel 3 is not curved, the volume of the hollow S2 is reduced. Further, as shown in FIG. 6, when the touch panel 3 is curved upward (in the direction of the arrow in FIG. 6), the elastic member 6 is pulled upward by the touch panel 3, and the second side wall 6b is recessed. To return to the original state. That is, the second side wall 6b is pulled upward following the upward curve of the touch panel 3. Thereby, the volume of hollow S2 will increase compared with the case where the touch panel 3 is curving below. That is, since the thickness T1 of the second side wall 6b is smaller than the thickness T2 of the first side wall 6a, the elastic member 6 can follow the vibration of the touch panel 3. Therefore, in the vibration device X1, the possibility that the vibration of the touch panel 3 is hindered can be reduced.

  The thickness T1 of the second side wall 6b is preferably 1/5 to 1/3 of the thickness T2 of the first side wall 6a. With this configuration, the elastic member 6 can easily follow the vibration of the touch panel 3.

  Further, since the elastic member 6 is positioned so as to surround the input region E1, the elastic member 6 can reduce the possibility of dust or water entering the internal space S1. For this reason, the vibration device X1 has a certain degree of dustproofness and waterproofness. Here, “having a certain degree of dustproofing and waterproofing” does not have to be completely dustproofing and waterproofing, but temporarily means that dust or water enters the internal space S1. If this can be achieved, it means "having a certain degree of dustproofness and waterproofness" in the present specification.

  In addition, in order to improve waterproofness more, it is preferable to use a waterproof double-sided tape for the double-sided tapes 71 and 72. In order to reduce the possibility that the vibration of the touch panel 3 is hindered, the double-sided tapes 71 and 72 preferably have a certain degree of elasticity.

In the above description, an example in which the elastic member 6 is positioned so as to surround the input region E1 has been described, but the present invention is not limited thereto. For example, a support member that is harder than the elastic member 6 is disposed at four corners of the touch panel 3, and a plurality of elastic members 6 are separately configured, and four elastic members 6 are provided between the support members. It may be. Further, the support 5 may be configured such that the end surface 3c of the touch panel 3 and the support 5 are in contact with each other, and the elastic member 6 may be provided in a portion where the end surface 3c of the touch panel 3 and the support 5 are separated from each other.

  The elastic member 6 is configured by arranging a rod-like elastic member having a hollow in a frame shape by bonding one surface and the other surface with an adhesive member. Moreover, when bonding one surface and the other surface with an adhesive member, a reinforcing member may be interposed in the hollow corresponding to the adhesive member. Thereby, the connection between one surface and the other surface can be reinforced by the reinforcing member. Moreover, you may arrange | position the elastic member 6 linearly between the said support members by providing the support member which has elasticity in the four corner | angular parts of the touch panel 3. FIG.

  Next, an operation example of the vibration device X1 will be described with reference to FIG.

  In the following, an operation example of the vibration device X1 when transmitting a pressing feeling to the user in the tactile transmission will be described. However, the vibration device X1 has a feeling other than the pressing feeling, such as a feeling of tracing, a feeling of touch, etc. Of course, the present invention can also be applied to transmitting various tactile sensations.

  As illustrated in FIG. 7, when the user presses the upper surface 3 a of the touch panel 3, the vibrating body 4 detects the pressing load on the touch panel 3 (Op 1). Here, the load detection function of the vibrating body 4 will be described. That is, when the user presses the upper surface 3a of the touch panel 3, the touch panel 3 is bent downward. When the touch panel 3 is bent downward, the vibrating body 4 is also bent downward. That is, the bending amount of the vibrating body 4 changes according to the pressing load on the touch panel 3. As a result, the pressing load on the touch panel 3 can be detected by the vibrating body 4.

  Then, the tactile transmission driver (not shown) determines whether or not the pressing load detected in Op1 is equal to or greater than the threshold when the input operation by the user is a pressing operation on the input object displayed on the display screen. (Op2).

  If the tactile transmission driver determines that the pressing load detected at Op1 is equal to or greater than the threshold (YES at Op2), the tactile transmission driver causes the vibrating body 4 to expand and contract in the short side direction of the touch panel 3 (Op3). Then, the touch panel 3 is curved and vibrated in the vertical direction by the vibrating body 4 expanded and contracted at Op3 (Op4). At this time, the elastic member 6 follows the bending vibration in the vertical direction of the touch panel 3. Thereby, a pressing feeling is transmitted to the user who pressed the upper surface 3a of the touch panel 3. On the other hand, if the tactile sensation transmission driver determines that the pressing load detected at Op1 is less than the threshold (NO at Op2), the process of FIG. 7 ends.

  As described above, the vibration device X1 can reduce the possibility that the vibration of the touch panel 3 is hindered while ensuring a certain degree of dustproofness and waterproofness.

  Next, the portable terminal P1 provided with said vibration apparatus X1 is demonstrated, referring FIG.

FIG. 8 is a perspective view illustrating a schematic configuration of the mobile terminal P1 according to the present embodiment. As shown in FIG. 8, the mobile terminal P1 is, for example, a mobile phone, a smartphone, or a PDA (Personal Digital).
Assistant) and the like, and includes the vibration device X1, the voice input unit 101, the voice output unit 102, the key input unit 103, and the housing 104.

The voice input unit 101 includes, for example, a microphone or the like, and inputs a user's voice or the like. The audio output unit 102 includes a speaker or the like, and outputs audio from the other party. The key input unit 103 is constituted by, for example, a mechanical key. Note that the key input unit 103 may be an operation key displayed on the display screen. The housing 104 has a role of accommodating the vibration device X1, the audio input unit 101, the audio output unit 102, and the key input unit 103.

  In addition, the mobile terminal P1 may include a short-distance wireless communication unit such as a digital camera function unit, a one-segment broadcasting tuner, an infrared communication function unit, and various interfaces, depending on the required functions. The detailed illustration and description thereof will be omitted.

  Since the portable terminal P1 includes the vibration device X1, it is possible to reduce the possibility that the vibration of the touch panel 3 is hindered while ensuring a certain degree of dustproofness and waterproofness.

  In addition, although the example which provided the audio | voice input part 101 in the portable terminal P1 was demonstrated above, it is not restricted to this. That is, the voice input unit 101 may not be provided in the mobile terminal P1.

  The vibration device X1 is a programmable display used for industrial purposes, a display used for in-vehicle use, an electronic notebook, a personal computer, a copying machine, a terminal device for games, instead of the portable terminal P1. It may be provided in various electronic devices such as a television and a digital camera.

  The above-described embodiment shows a specific example of the embodiment of the present invention, and various modifications can be made. Hereinafter, some main modifications will be described.

[Modification 1]
FIG. 9 is a plan view illustrating a schematic configuration of the vibration device X2 according to the first modification. 10 is a cross-sectional view taken along a cutting line III-III shown in FIG. 9 and 10, the same reference numerals are given to configurations having the same functions as those in FIGS. 1 and 2, and detailed descriptions thereof are omitted.

  As shown in FIGS. 9 and 10, the vibration device X2 includes an elastic member 61 instead of the elastic member 6 described in the above embodiment. The elastic member 61 surrounds the input area E1 and is located in the non-input area E2 of the touch panel 3. That is, the elastic member 61 is provided in a frame shape along the long side and the short side of the touch panel 3. Examples of the constituent material of the elastic member 61 include silicone rubber, urethane rubber, urethane foam, and other rubbers.

  The elastic member 61 has a hollow S2. For this reason, the elastic member 61 has the 1st side wall 61a and the 2nd side wall 61b located in the input area E1 side rather than the 1st side wall 61a. The thickness of the second side wall 61b is smaller than the thickness of the first side wall 61a.

  The elastic member 61 is connected to the lower surface 3 b of the touch panel 3 via the double-sided tape 71 and is also connected to the end surface 3 c of the touch panel 3. For this reason, the double-sided tape 71 is provided not only on the lower surface 3b of the touch panel 3 but also on the end surface 3c. The elastic member 61 has a first extending portion 61c. The first extending portion 61c is a portion of the elastic member 61 that extends upward from the first side wall 61a. Thereby, the first extending portion 61 c is connected to the end surface 3 c of the touch panel 3 via the double-sided tape 71.

The elastic member 61 is connected to the lower surface 3 b of the touch panel 3 and is also connected to the end surface 3 c of the touch panel 3. For this reason, the vibration device X2 has a larger connection area between the touch panel 3 and the elastic member 61 than the vibration device X1, and can improve the connection strength between the touch panel 3 and the elastic member 61. Further, the vibration device X2 can reduce the possibility that unnecessary vibration in the long side direction or the short side direction of the touch panel 3 is generated in the touch panel 3.

  As described above, the vibration device X2 has the following effects in addition to the same effects as the vibration device X1. That is, the vibration device X2 can improve the connection strength between the touch panel 3 and the elastic member 61 as compared with the vibration device X1, and unnecessary vibration in the long side direction or the short side direction of the touch panel 3 3 can be reduced.

[Modification 2]

  As shown in FIGS. 11 and 12, the vibration device X3 includes a support body 51 instead of the support body 5 described in the above embodiment. The support body 51 includes a base body 511 and a frame body 512. The base 511 has a main surface 511a. The liquid crystal panel 2 is provided on the main surface 511 a of the base 511. The frame 512 is provided so as to surround the liquid crystal panel 2 and the touch panel 3. Here, the base body 511 and the frame body 512 may be formed integrally or separately. Examples of the constituent material of the support 51 include a resin such as polycarbonate and a metal such as stainless steel, aluminum, and a magnesium alloy.

  The elastic member 61 located on the end surface 3 c of the touch panel 3 is sandwiched between the end surface 3 c of the touch panel 3 and the frame body 512. Specifically, the first side wall 61a and the first extending portion 61c are in contact with the inner wall surface 512a of the frame body 512, and the first extending portion 61c is connected to the end surface 3c of the touch panel 3 and the inner wall surface of the frame body 512. It is sandwiched between 512a. For this reason, the vibration device X3 can improve the connection strength between the touch panel 3 and the elastic member 61 compared with the vibration device X2. Further, the vibration device X3 can reduce the possibility that unnecessary vibrations in the long side direction or the short side direction of the touch panel 3 are generated in the touch panel 3 as compared with the vibration device X2.

  As described above, the vibration device X3 has the following effects in addition to the same effects as the vibration device X2. That is, the vibration device X3 can improve the connection strength between the touch panel 3 and the elastic member 61 as compared with the vibration device X2, and unnecessary vibration in the long side direction or the short side direction of the touch panel 3 3 can be reduced.

[Modification 3]
FIG. 13 is a plan view illustrating a schematic configuration of the vibration device X4 according to the third modification. FIG. 14 is a cross-sectional view taken along the cutting line VV shown in FIG. 13 and 14, the same reference numerals are given to configurations having the same functions as those in FIGS. 11 and 12, and detailed descriptions thereof are omitted.

As shown in FIGS. 13 and 14, in the vibration device X4, the elastic member 61 is also connected to the upper surface 3a of the touch panel 3. For this reason, the double-sided tape 71 is provided not only on the lower surface 3b and the end surface 3c of the touch panel 3 but also on the upper surface 3a. The elastic member 61 further has a second extending portion 61d. The second extending portion 61 d extends from the first extending portion 61 c to the upper surface 3 a of the touch panel 3 and extends from the first extending portion 61 c to the outer wall surface 512 b of the frame 512 in the elastic member 61. It is a part. As a result, the second extending portion 61 d is also connected to the upper surface 3 a of the touch panel 3 via the double-sided tape 71.

  The non-input area E2 of the touch panel 3 includes a second extending portion 61d located on the upper surface 3a of the touch panel 3 and an elastic member 61 (in the third modification example, the first extending portion 61c and the first extending portion 61b located on the lower surface 3b of the touch panel 3). Between the two side walls 61b). For this reason, the vibration device X4 can reduce the possibility that the touch panel 3 is detached from the elastic member 61.

  Here, let us consider a case where a force is applied to the vibration device X4 from the outside, such as when the vibration device X4 falls. In this case, the double-sided tape 71 positioned between the lower surface 3 b and the end surface 3 c of the touch panel 3 and the elastic member 61 may be peeled off from the touch panel 3 or the elastic member 61. When the double-sided tape 71 is peeled off, the touch panel 3 may be detached from the elastic member 61. However, in the vibration device X4, the non-input area E2 of the touch panel 3 is sandwiched between the second extending portion 61d located on the upper surface 3a of the touch panel 3 and the elastic member 61 located on the lower surface 3b of the touch panel 3. The possibility that the touch panel 3 is detached from the elastic member 61 can be reduced.

  As described above, the vibration device X4 has the following effects in addition to the same effects as the vibration devices X1 to X3. That is, the vibration device X4 can reduce the possibility that the touch panel 3 is detached from the elastic member 61.

  The elastic member 61 is preferably connected to the outer wall surface 512b of the frame body 512. Specifically, it is preferable that the second extending portion 61d is also connected to the outer wall surface 512b of the frame body 512 through an adhesive means such as a double-sided tape. Thereby, possibility that the touch panel 3 will detach | leave from the elastic member 61 can be reduced more. Further, in order to further reduce the possibility of the touch panel 3 being detached from the elastic member 61, as shown in FIG. Good. Accordingly, the second extending portion 61d can connect not only the upper surface but also the side surface of the outer wall surface 512b of the frame body 512. Thereby, the possibility that the touch panel 3 is detached from the elastic member 61 can be reliably reduced.

  When the elastic member 61 has the second extending portion 61d extending to the side surface of the outer wall surface 512b of the frame body 512, the lower wall 61e of the elastic member 61 is separated from the base 511 as shown in FIG. It is preferable. Thereby, it is possible to reduce the possibility that the vibration of the touch panel 3 is hindered while reducing the possibility that the touch panel 3 is detached from the elastic member 61. In the elastic member 61, the lower wall 61e is a part adjacent to the first side wall 61a and the second side wall 61b.

  The configuration in which the lower wall 61e of the elastic member 61 is separated from the base 511 can also be applied to the vibration device X3 shown in FIG. 12 or the vibration device X4 shown in FIG.

That is, the liquid crystal panel 21 is a so-called in-cell touch display in which a function as a touch panel is incorporated. The liquid crystal panel 21 has an input area E1 and a non-input area E2. The input area E1 is an area where the user can perform an input operation. The non-input area E2 is an area where the user cannot perform an input operation.

  The liquid crystal panel 21 has an upper surface 21a, a lower surface 21b located on the opposite side of the upper surface 21a, and four end surfaces 21c adjacent to the upper surface 21a and the lower surface 21b. That is, the upper surface 21a of the liquid crystal panel 21 corresponding to the input area E1 is a surface directly operated by the user with a finger or a pen. Further, as shown in FIG. 21, the liquid crystal panel 21 is disposed to face the support 5 with the internal space S1 therebetween.

  The liquid crystal panel 21 includes one substrate, the other substrate disposed opposite the one substrate, a liquid crystal layer interposed between the one substrate and the other substrate, and a display interposed between the one substrate and the other substrate. A display member layer that contributes to the above, a light detection portion provided on one substrate, and a backlight that irradiates light to the one substrate and the other substrate. This light detection unit corresponds to an input position detection function. By placing a finger on the liquid crystal panel 21 in a state where external light is incident on the light detection unit, external light incident on the light detection unit corresponding to the finger is blocked. Thereby, in the liquid crystal panel 21, the input position can be detected by comparing the detection level of the light detection unit in which external light is incident with the detection level of the light detection unit in which no external light is incident. it can.

  In addition, although the example of the in-cell type touch display was demonstrated as the liquid crystal panel 21 above, it is not restricted to this. For example, the liquid crystal panel may be a so-called on-cell touch display in which detection electrodes for detecting an input position are directly formed on the other substrate constituting the liquid crystal panel. Further, even an in-cell touch display may employ a method other than the above-described light detection method.

  Instead of the liquid crystal panel 21, a display panel such as a plasma panel, an organic EL panel, or electronic paper may be used.
