The vibration structure described in Patent Document 1 includes a membrane, a frame-like member, a vibrating part, a support part, a first connecting member, and a second connecting member. The frame-like member has a frame shape with an opening when viewed along the normal direction of the frame-like member. The vibrating part is located within the opening when viewed along the normal direction of the frame-like member. The support part connects the frame-like member and the vibrating part. Through elastic deformation of the support part, the vibrating part can be displaced relative to the frame-like member.

[0003] Furthermore, the membrane has a rectangular shape with a first end and a second end. A first connecting member secures the first end of the membrane to the vibrating part. A second connecting member secures the second end of the membrane to the frame member.

[0054] [Implementation Method]

[0055] Hereinafter, with reference to the accompanying drawings, the structure of a vibration device 10 according to one embodiment of the present invention will be described. Figure 1 It is a cross-sectional view obtained by looking at the electronic device 100 from the front. Figure 2 This is a top view obtained by looking down at the vibration device 10. Figure 3 This is a top view obtained by looking down at the support member 3. Figure 4 This is a top view obtained by looking down at the elastic connecting part 33. Figure 5 This is a top view obtained by looking down at actuator 4. Figure 6 This is a cross-sectional view showing the comparative example vibration device 1010 falling and colliding with the ground 6 with the fixed part 31 located above the movable part 32.

[0056] Figure 7 This is a cross-sectional view showing the directions of forces F1, F2, and F3 when the vibrating device 10 collides with the ground 6 with the fixed part 31 located above the movable part 32.

[0057] like Figure 1 As shown, as an example, the vibration device 10 is used in an electronic device 100 to provide tactile feedback to the user 200 by causing the vibrating member 2 to vibrate when the user 200 presses it. When the user 200 presses the vibrating member 2, the vibrating member 2 vibrates, so the user 200 can feel the pressure on the vibrating member 2. Thus, the vibration device 10 is mounted on the vibrating member 2.

[0058] Shell 1 is a rectangular box. For example... Figure 1 As shown, an opening OP is provided in the housing 1. More specifically, the opening OP has a rectangular shape when viewed along the vertical direction. Figure 1 As shown, the opening OP extends through the upper surface of the housing 1 in the vertical direction.

[0059] like Figure 1 As shown, the vibrating member 2 has a plate shape. Therefore, the vibrating member 2 has an upper principal surface US2 and a lower principal surface LS2 arranged in the vertical direction. The upper principal surface US2 is located above the lower principal surface LS2. The upper principal surface US2 and the lower principal surface LS2 are parallel to each other. The upper principal surface US2 and the lower principal surface LS2 are each rectangular in shape, having a long side extending in the left-right direction and a short side extending in the front-back direction.

[0060] like Figure 1 As shown, the vertical position of the vibrating member 2 is the same as the vertical position of the upper surface of the housing 1. Furthermore, the vibrating member 2 is located within the opening OP when viewed vertically. Therefore, the user 200 can press the upper main surface US2 of the vibrating member 2. Moreover, the vibrating member 2 does not contact the housing 1.

[0061] like Figure 2 As shown, the vibration device 10 includes a support member 3 and an actuator 4. (As indicated...) Figure 3 As shown, the support member 3 includes a fixed part 31, a movable part 32, and an elastic connecting part 33. The movable part 32, the elastic connecting part 33, and the fixed part 31 are arranged sequentially from left to right. The support member 3 is made of metals such as SUS (Stainless Used Steel). The support member 3 is manufactured by punching a piece of SUS sheet.

[0062] like Figure 1 As shown, the fixing part 31 is fixed to the housing 1. More specifically, as... Figure 3 As shown, the fixing part 31 has two threaded holes 311. The fixing part 31 is fixed to the housing 1 by inserting bolts 5 from below each of the two threaded holes 311 into the respective threaded holes 311 in the two threaded holes 311 and into the respective threaded holes in the two threaded holes (not shown) of the housing 1.

[0063] like Figure 1 As shown, the movable part 32 supports the vibrating member 2. The movable part 32 has an upper main surface US32 and a lower main surface LS32 arranged in the vertical direction. The upper main surface US32 is located above the lower main surface LS32. The upper main surface US32 and the lower main surface LS32 are parallel to each other. Figure 3 As shown, the upper main surface US32 and the lower main surface LS32 each have the following rectangular shape: the rectangle has a long side extending in the left-right direction and a short side extending in the front-back direction.

[0064] like Figure 3 As shown, the movable part 32 has a slit 321. The slit 321 extends through the movable part 32 in the vertical direction. When viewed in the vertical direction, the slit 321 has a shape that extends in the front-back direction. The slit 321 has a rectangular shape with a short side extending in the left-right direction and a long side extending in the front-back direction. When viewed in the left-right direction, the slit 321 overlaps with the elastic connecting part 33.

[0065] like Figure 3As shown, the elastic connecting part 33 elastically connects the fixed part 31 and the movable part 32 in the left-right direction. More specifically, the movable part 32 is elastically connected to the fixed part 31 in the left-right direction via the elastic connecting part 33. Therefore, the movable part 32 can vibrate relative to the fixed part 31 in any direction. Any direction refers to the left-right direction, the front-back direction, or the up-down direction, etc. Therefore, the elastic connecting part 33 has a first elastic modulus k1 in the left-right direction and a second elastic modulus k2 in the up-down direction. Furthermore, the second elastic modulus k2 is smaller than the first elastic modulus k1.

[0066] like Figure 4 As shown, the elastic connecting portion 33 has a first curved portion 331, a second curved portion 332, a third curved portion 333, a first connecting portion 334, and a second connecting portion 335. The first curved portion 331, the second curved portion 332, and the third curved portion 333 are elastically deformable. Furthermore, the first curved portion 331, the second curved portion 332, and the third curved portion 333 are arranged sequentially from left to right when viewed along the front-back direction.

[0067] like Figure 4 As shown, the first curved portion 331 has a shape that bends forward. Furthermore, the left end of the first curved portion 331 has a shape that extends in the front-rear direction. Therefore, the elastic connecting portion 33 has a shape that extends in the front-rear direction. Additionally, the right end of the first curved portion 331 has a shape that extends from the right front to the left rear.

[0068] like Figure 4 As shown, the second curved portion 332 includes a shape that curves rearward. Furthermore, the second curved portion 332 has an inner edge I332 and an outer edge O332. The inner edge I332 and the outer edge O332 are respectively the inner edge and outer edge of an arc. Therefore, the length of the outer edge O332 is longer than the length of the inner edge I332, and the radius of curvature of the outer edge O332 is equal to the radius of curvature of the inner edge I332. Additionally, the left end of the second curved portion 332 has a shape extending from the right front to the left rear. Furthermore, the right end of the second curved portion 332 has a shape extending from the left front to the right rear.

[0069] like Figure 4 As shown, the third curved portion 333 has a shape that curves forward. Furthermore, the left end of the third curved portion 333 has a shape that extends from the left front to the right rear. Additionally, the right end of the third curved portion 333 has a shape that extends in the front-rear direction.

[0070] like Figure 4 As shown, the shortest distance LRMIN13 in the left-right direction between the first bend 331 and the third bend 333 is shorter than the longest distance LRMAXO2 in the left-right direction of the outer edge O332 of the second bend 332.

[0071] like Figure 3 and Figure 4 As shown, the first connecting part 334 connects the movable part 32 and the first curved part 331. (As indicated...) Figure 4 As shown, the first connecting portion 334 has a shape that extends along the first direction DIR1. Alternatively, the first connecting portion 334 may simply include a shape that extends along the first direction DIR1.

[0072] like Figure 4 As shown, when viewed along the vertical direction, the first direction DIR1 forms a first angle θ1 counterclockwise relative to the horizontal direction. The first angle θ1 is an angle greater than 0 degrees in the counterclockwise direction and less than 90 degrees in the counterclockwise direction. That is, the first direction DIR1 differs from the horizontal direction when viewed along the vertical direction. In this embodiment, the first angle θ1 is an angle greater than 30 degrees in the counterclockwise direction and less than 90 degrees in the counterclockwise direction.

[0073] like Figure 3 and Figure 4 As shown, the second connecting part 335 connects the fixing part 31 and the third bending part 333. (As indicated...) Figure 4 As shown, the second connecting portion 335 has a shape that extends along the second direction DIR2. Alternatively, the second connecting portion 335 may simply include a shape that extends along the second direction DIR2.

[0074] like Figure 4 As shown, when viewed along the vertical direction, the second direction DIR2 forms a second angle θ2 in a clockwise direction relative to the left-right direction. The second angle θ2 is an angle greater than 0 degrees in the clockwise direction and less than 90 degrees in the clockwise direction. That is, the second direction DIR2 differs from the left-right direction when viewed along the vertical direction. In this embodiment, the second angle θ2 is an angle greater than 30 degrees in the clockwise direction and less than 90 degrees in the clockwise direction.

[0075] like Figure 5 As shown, actuator 4 includes a piezoelectric film 41, a first electrode (not shown), and a second electrode (not shown). Actuator 4 has a film shape.

[0076] like Figure 1 As shown, actuator 4 has a first main surface US4 and a second main surface LS4. The first main surface US4 is located above the second main surface LS4. The first main surface US4 and the second main surface LS4 are parallel to each other. The first main surface US4 is the upper surface of the first electrode. The second main surface LS4 is the lower surface of the second electrode. Figure 5As shown, the first principal surface US4 and the second principal surface LS4 have the following rectangular shape when viewed along the vertical direction: the rectangular shape has a long side extending along the horizontal direction and a short side extending along the front-back direction.

[0077] The piezoelectric film 41 is a piezoelectric element. That is, the actuator 4 includes a piezoelectric element. Furthermore, the piezoelectric film 41 has an upper surface and a lower surface. A first electrode is disposed on the upper surface of the piezoelectric film 41 (not shown). A second electrode is disposed on the lower surface of the piezoelectric film 41 (not shown). The first electrode and the second electrode are metal coatings formed by vapor deposition.

[0078] like Figure 2 As shown, the actuator 4 is mounted on the fixed part 31 and the movable part 32 of the support member 3. More specifically, the left end of the actuator 4 is mounted on the movable part 32 by means of an adhesive material (not shown) when the actuator 4 is slightly stretched in the left-right direction, and the right end of the actuator 4 is mounted on the fixed part 31 by means of an adhesive material (not shown) when the actuator 4 is slightly stretched in the left-right direction.

[0079] The actuator 4 is extended and retracted in the left-right direction by applying an alternating voltage to it. More specifically, the piezoelectric film 41 is extended and retracted in the left-right direction by applying an alternating voltage between the first electrode and the second electrode. For example, the actuator 4 is stretched in the left-right direction by applying a positive voltage. On the other hand, the actuator 4 is contracted in the left-right direction by applying a negative voltage. Therefore, the actuator 4 vibrates in the left-right direction by applying an alternating voltage. As a result, the actuator 4 causes the movable part 32 of the vibrated member 2 and the supporting member 3 to vibrate in the left-right direction. Furthermore, the alternating voltage is a voltage that changes periodically between positive and negative values.

[0080] [Effect]

[0081] like Figure 6 As shown, assuming the fixed part 31 is above the movable part 32, the comparative example vibration device 1010 falls and collides with the ground 6. Hereinafter, Figure 6 and Figure 7 The vertical direction is defined as the vertical direction. Figure 6 and Figure 7 In this context, the direction u is defined as vertically upward. Figure 6 and Figure 7 In this context, the direction d is defined as vertically downward. Additionally, [the following is a partial translation of the original text, which is not possible without further context]. Figure 6 and Figure 7 The left and right directions and the front and back directions are defined as the horizontal left and right directions and the horizontal front and back directions, respectively. Figure 6 and Figure 7 The direction l in the middle is defined as horizontal to the left. Figure 6 and Figure 7 The direction r in the equation is defined as horizontal to the right. Additionally, [the following is a partial translation of the original text, which is not translated here]. Figure 6 and Figure 7 In the equation, the direction f is defined as horizontal forward. Figure 6 and Figure 7 In this context, direction b is defined as horizontal rear. The vertical up-down direction aligns with the horizontal left-right direction. The horizontal left-right direction aligns with the front-back direction. The horizontal front-back direction aligns with the up-down direction. The vertical up-down direction, the horizontal left-right direction, and the horizontal front-back direction are all orthogonal to each other.

[0082] The comparative example vibration device 1010 differs from the comparative example vibration device 10 in that the second elastic modulus k2 is greater than or equal to the first elastic modulus k1. Furthermore, the shape of the comparative example vibration device 1010 is identical. When the comparative example vibration device 1010 collides with the ground 6, the comparative example vibration device 1010 receives the impact force F from the ground 6, and the elastic connecting part 33 also receives the impact force F. The second elastic modulus k2 is greater than or equal to the first elastic modulus k1. Therefore, the elastic connecting part 33 is more easily deformed in the left-right direction than in the vertical direction. Thus, the elastic connecting part 33 is more easily deformed in the vertical direction (…). Figures 1 to 5 The actuator 4 contracts in the left-right direction. As a result, the actuator 4 relaxes. Therefore, the vibration of the actuator 4 is difficult to transmit to the vibrated component 2.

[0083] Therefore, in the vibration device 10, the second elastic modulus k2 is smaller than the first elastic modulus k1. Consequently, the elastic connecting part 33 is more easily deformed in the vertical direction than in the horizontal direction. Therefore, when the vibration device 10 collides with the ground 6, the elastic connecting part 33 can deform in the vertical direction (…). Figures 1 to 5 In addition to elastic deformation in the left-right direction, it can also deform in the horizontal front-back direction. Figures 1 to 5 The elastic deformation occurs in the vertical direction. Therefore, according to the vibration device 10, the elastic region of the elastic connection 33 is expanded. Therefore, a greater force is required to plastically deform the elastic connection 33. Therefore, according to the vibration device 10, the elastic connection 33 is difficult to plastically deform. As a result, according to the vibration device 10, the drop resistance of the vibration device can be improved.

[0084] According to the vibration device 10, the drop resistance of the vibration device can be further improved. More specifically, the elastic connecting part 33 has a first bend 331 that is elastically deformable, a second bend 332 that is elastically deformable, and a third bend 333 that is elastically deformable. In addition, the first bend 331, the second bend 332, and the third bend 333 are arranged sequentially from left to right when viewed in the front-back direction. The first bend 331 and the third bend 333 have a shape that bends in a forward-protruding manner, and the second bend 332 has a shape that bends in a rearward-protruding manner. Thus, when the vibration device 10 collides with the ground 6, the second bend 332 can bend in the horizontal front-back direction ( Figures 1 to 5 In the vertical direction, the second bend 332 is elastically deformable. More specifically, neither end of the second bend 332 is fixed. Therefore, the outer edge O332 and the inner edge I332 of the second bend 332 are easily deformed in the vertical direction. Consequently, the elastic connecting portion 33 is easily deformable in the horizontal front-back direction. Figures 1 to 5 The elastic and torsional deformation in the vertical direction expands the elastic region of the elastic connection 33. Therefore, a greater force is required to plastically deform the elastic connection 33. Therefore, according to the vibration device 10, the elastic connection 33 is difficult to plastically deform. As a result, the drop resistance of the vibration device 10 can be further improved.

[0085] According to the vibration device 10, the drop resistance of the vibration device can be further improved. More specifically, the shortest distance LRMIN13 in the left-right direction between the first bend 331 and the third bend 333 is shorter than the longest distance LRMAXO2 in the left-right direction of the outer edge O332 of the second bend 332. Therefore, the right end of the first bend 331 and the left end of the second bend 332 each have a shape extending from the right front to the left rear. Furthermore, the right end of the second bend 332 and the left end of the third bend 333 each have a shape extending from the left front to the right rear. When the vibration device 10 collides with the ground 6, as... Figure 7 As shown, forces F1 are applied to the right end of the first bend 331 and the left end of the second bend 332, as well as the right end of the second bend 332 and the left end of the third bend 333. As a result, the shortest distance LRMIN13 in the left-right direction between the first bend 331 and the third bend 333 becomes shorter, and the second bend 332 is more easily bent in the horizontal front-back direction (…). Figures 1 to 5 The second bend 332 is prone to warping in the horizontal front-back direction. Figures 1 to 5 The elastic connection 33 undergoes elastic deformation in the vertical direction. Therefore, a greater force is required to plastically deform the elastic connection 33. Consequently, according to the vibration device 10, the elastic connection 33 is difficult to plastically deform. As a result, according to the vibration device 10, the drop resistance of the vibration device can be further improved.

[0086] According to the vibration device 10, the drop resistance of the vibration device can be further improved. More specifically, the first connecting portion 334 includes a shape extending along the first direction DIR1. The first direction DIR1 forms an angle greater than 0 degrees in the counterclockwise direction and less than 90 degrees in the counterclockwise direction relative to the left and right direction when viewed in the vertical direction. Therefore, when the vibration device 10 collides with the ground 6, as Figure 7As shown, a force F2 is applied to the first connecting portion 334. Using force F2, a torsion is generated between the first connecting portion 334 and the first bent portion 331. As a result, the first bent portion 331 twists relative to itself, and consequently, the second bent portion 332 is more prone to twisting in the horizontal front-back direction. Figures 1 to 5 The elastic connecting part 33 is easily deformed in the vertical direction. Therefore, the elastic connecting part 33 is easy to deform in the horizontal front-back direction. Figures 1 to 5 The elastic and torsional deformation in the vertical direction expands the elastic region of the elastic connection 33. Therefore, a greater force is required to plastically deform the elastic connection 33. Therefore, according to the vibration device 10, the elastic connection 33 is difficult to plastically deform. As a result, the drop resistance of the vibration device 10 can be further improved.

[0087] According to the vibration device 10, the drop resistance of the vibration device can be further improved. More specifically, the second connecting portion 335 includes a shape extending along the second direction DIR2. The second direction DIR2 forms an angle greater than 0 degrees in the clockwise direction and less than 90 degrees in the clockwise direction relative to the left and right direction when viewed in the vertical direction. Therefore, when the vibration device 10 collides with the ground 6, as Figure 7 As shown, a force F3 is applied to the second connecting portion 335. Using force F3, a torsion is generated between the second connecting portion 335 and the third curved portion 333. As a result, the third curved portion 333 twists relative to the second connecting portion 335, and consequently, the second curved portion 332 is more prone to twisting in the horizontal front-back direction (…). Figures 1 to 5 The elastic connecting part 33 is easily deformed in the vertical direction. Therefore, the elastic connecting part 33 is easy to deform in the horizontal front-back direction. Figures 1 to 5 The elastic and torsional deformation in the vertical direction expands the elastic region of the elastic connection 33. Therefore, a greater force is required to plastically deform the elastic connection 33. Therefore, according to the vibration device 10, the elastic connection 33 is difficult to plastically deform. As a result, the drop resistance of the vibration device 10 can be further improved.

[0088] According to the vibration device 10, the drop resistance of the vibration device can be further improved. More specifically, the movable part 32 has a slit 321 that extends through the movable part 32 in the vertical direction. When viewed in the vertical direction, the slit 321 has a shape that extends in the front-back direction. In addition, when viewed in the left-right direction, the slit 321 overlaps with the elastic connecting part 33. As a result, the portion of the movable part 32 located between the slit 321 and the elastic connecting part 33 is easily deformable. As a result, the impact force F received by the vibration device 10 from the ground 6 is dispersed into a force that contributes to the deformation of the elastic connecting part 33 and a force that contributes to the deformation of the movable part 32. Therefore, a larger force is required to plastically deform the elastic connecting part 33. Therefore, according to the vibration device 10, the elastic connecting part 33 is difficult to plastically deform. As a result, according to the vibration device 10, the drop resistance of the vibration device can be further improved.

[0089] [Other Implementation Methods]

[0090] The vibration device of this utility model is not limited to the vibration device 10, and can be modified within the scope of its main idea.

[0091] Alternatively, it could be, such as Figure 1 As shown, the vibration device 10 and the vibrated component 2 are modularly configured as the vibration device 20.

[0092] Alternatively, it could be, such as Figure 1 As shown, the vibration device 10 and the housing 1 are modularly configured as an electronic device 30.

[0093] Alternatively, it could be, such as Figure 1 As shown, the vibration device 10, housing 1, and vibrated component 2 are modularly configured as an electronic device 100. Furthermore, the purpose of the electronic device 100 is not limited to providing tactile feedback to the user 200.

[0094] Alternatively, the actuator 4 can be mounted on the fixed part 31 of the support member 3 and the vibrated member 2.

[0095] Alternatively, when viewed along the vertical direction, the first direction DIR1 can form a first angle θ1 that is larger than 45 degrees counterclockwise relative to the horizontal direction and smaller than 90 degrees counterclockwise. Alternatively, when viewed along the vertical direction, the second direction DIR2 can form a second angle θ2 that is larger than 45 degrees clockwise relative to the horizontal direction and smaller than 90 degrees clockwise. In this case, the drop resistance of the vibration device can be further improved.

[0096] Alternatively, when viewed along the vertical direction, the first direction DIR1 can form a first angle θ1 that is larger than 60 degrees counterclockwise relative to the horizontal direction and smaller than 90 degrees counterclockwise. Alternatively, when viewed along the vertical direction, the second direction DIR2 can form a second angle θ2 that is larger than 60 degrees clockwise relative to the horizontal direction and smaller than 90 degrees clockwise. In this case, the drop resistance of the vibration device can be further improved.

[0097] Furthermore, the vibration device 10 is not limited to use in electronic equipment 100.

[0098] Furthermore, the vibrating component 2 is not limited to being pressed by the user 200, but can also be pressed by the operating component.

[0099] Furthermore, the housing 1 is not limited to a box with a cuboid shape.

[0100] Alternatively, the opening OP may not have a rectangular shape when viewed along the vertical direction.

[0101] Alternatively, the vibrating member 2 may not have a plate shape. Additionally, the vibrating member 2 may not have an upper principal surface US2 and a lower principal surface LS2 arranged in the vertical direction. Furthermore, the upper principal surface US2 and the lower principal surface LS2 may not be parallel to each other.

[0102] Alternatively, the upper main surface US2 and the lower main surface LS2 may not have the following rectangular shape: the rectangle has a long side extending in the left-right direction and a short side extending in the front-back direction.

[0103] Alternatively, the vertical position of the vibrating member 2 may differ from the vertical position of the upper surface of the housing 1.

[0104] Alternatively, the vibrating member 2 may not be located within the opening OP when viewed along the vertical direction.

[0105] Alternatively, the vibrating component 2 may come into contact with the housing 1.

[0106] Alternatively, the material of the support member 3 may not be a metal such as SUS (Stainless Used Steel).

[0107] Alternatively, the support member 3 may not be manufactured by punching a single SUS sheet.

[0108] Alternatively, the fixing part 31 can be fixed to the housing 1 using an adhesive material. Therefore, the fixing part 31 may not have a threaded hole 311. Alternatively, the housing 1 may not have a threaded hole. Furthermore, the bolt 5 is not a necessary component.

[0109] Furthermore, when the fixing part 31 has a threaded hole 311, it is preferable that there are two or more threaded holes 311. When there is only one threaded hole 311, the fixing part 31 is prone to rotate around the threaded hole 311 when viewed in the vertical direction due to the vibration of the actuator 4. When the fixing part 31 rotates around the threaded hole 311 when viewed in the vertical direction due to the vibration of the actuator 4, a portion of the vibration energy of the actuator 4 causing the movable part 32 of the vibrating member 2 and the supporting member 3 to vibrate in the left-right direction is consumed by the rotation of the fixing part 31. Therefore, the efficiency of the actuator 4 in causing the movable part 32 of the vibrating member 2 and the supporting member 3 to vibrate in the left-right direction is reduced. On the other hand, by having two or more threaded holes 311 in the fixing part 31, the situation where a portion of the vibration energy is consumed by the rotation of the fixing part 31 can be suppressed. By having two or more threaded holes 311 in the fixing part 31, the actuator 4 can efficiently cause the movable part 32 of the vibrating member 2 and the supporting member 3 to vibrate in the left-right direction.

[0110] Alternatively, the upper principal plane US32 and the lower principal plane LS32 may not be parallel to each other.

[0111] Alternatively, the upper main surface US32 and the lower main surface LS32 may not have the following rectangular shape: the rectangular shape has a long side extending in the left-right direction and a short side extending in the front-back direction.

[0112] Alternatively, the slit 321 may not have the following rectangular shape: the rectangular shape has a short side extending in the left-right direction and a long side extending in the front-back direction.

[0113] Alternatively, actuator 4 may not contain a piezoelectric element. Actuator 4 may also be, for example, an LRA (Linear Resonant Actuator).

[0114] Alternatively, the radius of curvature of the outer edge O332 may be different from that of the inner edge I332.

[0115] Furthermore, in this embodiment, drop resistance refers to the difficulty of plastic deformation.
