[0056] [First embodiment]

[0057] Hereinafter, a support device 20 according to a first embodiment of the present invention will be described with reference to the drawings. Figure 1 It is a cross-sectional view taken along line AA of the housing 1 , the vibrated member 2 , the actuator 4 , and the support device 20 according to the first embodiment.

Figure 5 These are a plan view and a cross-sectional view of the second sensor 52 in the first embodiment in a state where the second sensor 52 is developed into a plane.

[0058] In this specification, directions are defined as follows. The up-down direction is the direction in which the normal to the upper main surface S1 of the vibrated component 2 extends. The left-right direction is the direction in which the long side of the upper main surface S1 of the vibrated component 2 extends. The left-right direction is orthogonal to the up-down direction. The front-back direction is the direction in which the short side of the upper main surface S1 of the vibrated component 2 extends. The front-back direction is orthogonal to the up-down direction and the left-right direction. In addition, the up-down direction, the left-right direction, and the front-back direction of this embodiment may not be consistent with the up-down direction, the left-right direction, and the front-back direction when the support device 20 is used.

[0059] As an example, Figure 1 As shown, the support device 20 can be used as an actuator unit that provides tactile feedback to the user 100 by vibrating the vibrated member 2 when the user 100 presses the vibrated member 2. Thus, when the user 100 presses the vibrated member 2, the vibrated member 2 vibrates, and the user 100 can feel that the vibrated member 2 is pressed.

[0060] In this embodiment, the housing 1 is a rectangular box. Figure 1 As shown, the housing 1 includes a first housing portion 1a, a second housing portion 1b, and a third housing portion 1c. The first housing portion 1a is the upper surface of the housing 1. The third housing portion 1c is the lower surface of the housing 1. The second housing portion 1b is a side surface of the housing 1. The second housing portion 1b is located between the first housing portion 1a and the third housing portion 1c when viewed in the front-to-back direction.

[0061] like Figure 1and Figure 2 As shown in FIG. 1 , an opening OP is provided in the housing 1. In more detail, as shown in FIG. Figure 2 As shown, the opening OP has a rectangular shape when viewed in the up-down direction. Figure 1 As shown in FIG. 1 , the opening OP passes through the first portion 1a of the housing in the vertical direction. Figure 2 As shown, the housing first portion 1a has a rectangular frame shape.

[0062] In this embodiment, as an example, Figure 1 As shown, the vibrated component 2 has a plate shape. Thus, the vibrated component 2 has an upper main surface S1 and a lower main surface S2 arranged in the vertical direction. The upper main surface S1 is located above the lower main surface S2. In this embodiment, the upper main surface S1 and the lower main surface S2 are parallel. In this embodiment, the upper main surface S1 and the lower main surface S2 each have a rectangular shape when viewed in the vertical direction. In addition, the upper main surface S1 and the lower main surface S2 each have a long side extending in the left-right direction and a short side extending in the front-back direction. That is, the upper main surface S1 has a rectangular shape when viewed in the vertical direction, and the rectangular shape has a front side located at the front end of the upper main surface S1, a rear side located at the rear end of the upper main surface S1, a left side located at the left end of the upper main surface S1, and a right side located at the right end of the upper main surface S1. In addition, the upper main surface S1 has a first angle formed by the front side and the left side, a second angle formed by the front side and the right side, a third angle formed by the rear side and the left side, and a fourth angle formed by the rear side and the right side.

[0063] In this embodiment, the vertical position of the vibrated member 2 is the same as the vertical position of the first portion 1a of the housing. Figure 1 and Figure 2 As shown in FIG. 1 , the vibrated member 2 is located in the opening OP when viewed in the vertical direction. Figure 1 As shown, the user 100 can come into contact with the upper main surface S1. That is, a part of the user 100's body comes into contact with the upper main surface S1. Thus, the user 100 applies a force to the vibrated member 2. In addition, the vibrated member 2 does not come into contact with the housing 1.

[0064] In this embodiment, the actuator 4 includes a first thin film 41, a first electrode (not shown), and a second electrode (not shown). The actuator 4 has a thin film shape.

[0065] In this embodiment, the first film 41 includes a piezoelectric body. That is, the actuator 4 includes a piezoelectric body. Furthermore, the first film 41 has an upper surface and a lower surface. A first electrode is provided on the upper surface of the first film 41 (not shown). A second electrode is provided on the lower surface of the first film 41 (not shown). The first and second electrodes are, for example, metal films formed by vapor deposition.

[0066] In this embodiment, if Figure 1As shown, the actuator 4 has a first principal surface S3 and a second principal surface S4. The first principal surface S3 is located above the second principal surface S4. The first principal surface S3 is the upper surface of the first electrode. The second principal surface S4 is the lower surface of the second electrode. In more detail, the first principal surface S3 and the second principal surface S4 each have a rectangular shape when viewed in the vertical direction. The first principal surface S3 and the second principal surface S4 each have a long side extending in the left-right direction and a short side extending in the front-back direction. In this embodiment, the first principal surface S3 and the second principal surface S4 are parallel to each other. In addition, the upper principal surface S1, the lower principal surface S2, the first principal surface S3, and the second principal surface S4 are parallel to each other.

[0067] like Figure 1 As shown, the actuator 4 is mounted on the lower main surface S2 of the vibrated member 2. Specifically, the actuator 4 is mounted on the lower main surface S2 of the vibrated member 2. More specifically, in this embodiment, the actuator 4 is mounted on the lower main surface S2 of the vibrated member 2 in a slightly extended position in the left-right direction. The right end of the actuator 4 is mounted on the lower main surface S2 of the vibrated member 2 with the aid of an adhesive (not shown).

[0068] As an example, Figure 2 As shown, the support device 20 includes a support member 3 and four sensors 5 .

[0069] like Figure 2 As shown in FIG. 3 , the supporting member 3 includes a supported portion 31, a supporting portion 32, and four elastic connecting members 33. Figure 2 As shown, the supporting member 3 has a frame shape surrounding the vibrated member 2 when viewed in the up-down direction.

[0070] In this embodiment, the supported portion 31 has a rectangular frame shape when viewed in the vertical direction. The supported portion 31 has a front long side, a rear long side, a right short side, and a left short side. Figure 1 and Figure 3 As shown, the supported portion 31 has a first portion P1 that does not overlap with the vibrated member 2 when viewed in the up-down direction. The first portion P1 is the front half of the front long side of the supported portion 31, the rear half of the rear long side of the supported portion 31, the left half of the left short side of the supported portion 31, and the right half of the right short side of the supported portion 31. The first portion P1 is located below the first portion 1a of the housing. Moreover, as shown in FIG. Figure 1 and Figure 3 As shown in FIG. 1 , the first portion P1 is supported by the housing 1. In more detail, as shown in FIG. Figure 1 and Figure 3 As shown, the first portion P1 is supported by the housing first portion 1 a of the housing 1 . Thus, the supported portion 31 is supported by the housing 1 .

[0071] like Figure 1As shown in FIG. 3 , the supporting portion 32 is connected to the supported portion 31. More specifically, the supporting portion 32 protrudes from the left short side of the inner edge of the supporting member 3 to the right. Figure 2 As shown in FIG. 1 , the support portion 32 overlaps the vibrated member 2 when viewed in the vertical direction. Figure 1 As shown in FIG. 1 , the support portion 32 is located below the lower main surface S2 of the vibrated member 2. Figure 1 As shown, the actuator 4 is mounted on the support portion 32. Specifically, the left end portion of the actuator 4 is mounted on the upper surface of the support portion 32 via an adhesive material (not shown). As described above, the support portion 32 supports the actuator 4.

[0072] In the present embodiment, the actuator 4 expands and contracts in the left-right direction by applying an AC voltage to the actuator 4. More specifically, the first film 41 expands and contracts in the left-right direction by applying a voltage to the first electrode and the second electrode. For example, the actuator 4 expands in the left-right direction by applying a positive voltage to the actuator 4. On the other hand, the actuator 4 contracts in the left-right direction by applying a negative voltage to the actuator 4. That is, the actuator 4 vibrates in the left-right direction by applying an AC voltage to the actuator 4. As a result, the actuator 4 vibrates the vibrated component 2. Therefore, in the present embodiment, the vibrated component 2 vibrates in the left-right direction. In addition, the AC voltage is a voltage whose positive and negative voltages change periodically.

[0073] The vibrated member 2 is supported on the housing 1 by means of a supporting member 3. More specifically, the vibrated member 2 is elastically connected to the housing 1 by means of four elastic connecting members 33. This allows the vibrated member 2 to vibrate in any direction relative to the housing 1. Any direction includes up and down, left and right, or front and back.

[0074] Here, the four elastic connecting members 33 are respectively set as a first elastic connecting member 331, a second elastic connecting member 332, a third elastic connecting member 333 and a fourth elastic connecting member 334. In this embodiment, Figure 2 As shown, the first elastic connecting member 331 overlaps with the first corner formed by the front and left sides of the upper main surface S1 when viewed in the vertical direction. Figure 2 As shown, the second elastic connecting member 332 overlaps with the second corner formed by the front and right sides of the upper main surface S1 when viewed in the up-down direction. Figure 2 As shown, the third elastic connecting member 333 overlaps with the third corner formed by the rear side and the left side of the upper main surface S1 when viewed in the vertical direction. Figure 2 As shown, the fourth elastic connecting member 334 overlaps with a fourth corner formed by the rear side and the right side of the upper main surface S1 when viewed in the up-down direction.

[0075] The first elastic connecting member 331 has a bilaterally symmetrical structure with the second elastic connecting member 332. The third elastic connecting member 333 has a point-symmetrical structure with the second elastic connecting member 332. The fourth elastic connecting member 334 has a front-back symmetrical structure with the second elastic connecting member 332. Therefore, the following description focuses on the second elastic connecting member 332, and the description of the first elastic connecting member 331, the third elastic connecting member 333, and the fourth elastic connecting member 334 is omitted.

[0076] like Figure 3 As shown, the second elastic connecting member 332 is attached to the supported portion 31. Furthermore, the second elastic connecting member 332 protrudes from the right front corner of the supported portion 31 toward the left rear. Furthermore, the left rear end of the second elastic connecting member 332 is fixed to the vibrated member 2. Thus, the supporting member 3 is attached to the vibrated member 2 via the second elastic connecting member 332. In other words, the supporting device 20 is attached to the vibrated member 2.

[0077] The second elastic connecting member 332 elastically connects the vibrated member 2 and the supported portion 31. In more detail, the second elastic connecting member 332 is an elastic member. The material of the second elastic connecting member 332 is, for example, metal or resin. Therefore, the second elastic connecting member 332 elastically deforms. In more detail, as Figure 4 As shown, the second elastic connecting member 332 includes an elastically deformable portion P33. The elastic deformation of the elastically deformable portion P33 elastically deforms the second elastic connecting member 332. This allows the vibrated member 2 to vibrate in any direction relative to the housing 1. In this embodiment, when the user 100 applies a force F in the vertical direction to the vibrated member 2, the vertical component of the deformation of the second elastic connecting member 332 is greater than the maximum deformation of the vibrated member 2 in a direction perpendicular to the vertical direction.

[0078] Here, the four sensors 5 are respectively set as a first sensor 51, a second sensor 52, a third sensor 53 and a fourth sensor 54. In this embodiment, Figure 2 As shown, the first sensor 51 is mounted on the first elastic connecting member 331. Figure 2 As shown, the second sensor 52 is mounted on the second elastic connecting member 332. Figure 2 As shown, the third sensor 53 is mounted on the third elastic connecting member 333. Figure 2 As shown, the fourth sensor 54 is attached to the fourth elastic connecting member 334. That is, the sensor 5 is attached to the elastic connecting member 33. Alternatively, the sensor 5 may be attached to at least any one of the first elastic connecting member 331, the second elastic connecting member 332, the third elastic connecting member 333, and the fourth elastic connecting member 334.

[0079] The first sensor 51 has a structure that is bilaterally symmetrical with the second sensor 52. The third sensor 53 has a structure that is point-symmetrical with the second sensor 52. The fourth sensor 54 has a structure that is front-back symmetrical with the second sensor 52. Therefore, the following description focuses on the second sensor 52, and the description of the first sensor 51, the third sensor 53, and the fourth sensor 54 is omitted.

[0080] The second sensor 52 is a sensor for detecting the force applied to the vibrated member 2. Figure 5 As shown, the second sensor 52 includes a thin film 521, a third electrode 52F, a fourth electrode 52B, a charge amplifier 522, and an integrating circuit 523. The second sensor 52 has a thin film shape.

[0081] like Figure 5 As shown, the second sensor 52 has a third principal surface S5 and a fourth principal surface S6. When the second sensor 52 is flattened, the third principal surface S5 and the fourth principal surface S6 each have a rectangular shape when viewed from the top and bottom. When the second sensor 52 is flattened, the third principal surface S5 and the fourth principal surface S6 each have a long side extending in the left-right direction and a short side extending in the front-back direction. In this embodiment, the third principal surface S5 and the fourth principal surface S6 are parallel. Furthermore, the third principal surface S5 is located above the fourth principal surface S6.

[0082] like Figure 5 As shown, film 521 has an upper surface and a lower surface. In this embodiment, film 521 includes a piezoelectric element. That is, second sensor 52 includes a piezoelectric element. Furthermore, film 521 is a piezoelectric film. More specifically, in this embodiment, film 521 is a PLLA film.

[0083] The film 521 generates an electric charge corresponding to the differential value of the displacement of the film 521. The polarity of the electric charge generated when the film 521 is stretched in the left-right direction is opposite to the polarity of the electric charge generated when the film 521 is stretched in the front-back direction. Specifically, the film 521 is a film formed from a chiral polymer. An example of a chiral polymer is polylactic acid (PLA), particularly L-type polylactic acid (PLLA). The main chain of PLLA formed from a chiral polymer has a helical structure. PLLA has piezoelectric properties due to uniaxial stretching and molecular orientation. The film 521 has a piezoelectric constant of d14.

[0084] In this embodiment, the uniaxial stretching axis OD of the film 521 forms an angle of 45 degrees counterclockwise relative to the left-right direction and an angle of 45 degrees clockwise relative to the front-back direction. In other words, the film 521 is stretched in at least a uniaxial direction. This 45-degree angle includes, for example, an angle of approximately 45 degrees ± 10 degrees. Thus, the film 521 generates an electric charge by deforming in such a way that the film 521 is stretched in the left-right direction or compressed in the left-right direction. For example, when the film 521 is deformed in such a way that it is stretched in the left-right direction, a positive electric charge is generated. For example, when the film 521 is deformed in such a way that it is compressed in the left-right direction, a negative electric charge is generated. The magnitude of the generated electric charge depends on the differential value of the displacement of the film 521 caused by the stretching or compression.

[0085] The third electrode 52F is a signal electrode. Figure 5 As shown, the third electrode 52F is provided on the upper surface of the film 521. The third electrode 52F covers the upper surface of the film 521. That is, the third main surface S5 is the upper surface of the third electrode 52F. The third electrode 52F is a metal film formed by vapor deposition, for example.

[0086] The fourth electrode 52B is a ground electrode. The fourth electrode 52B is connected to the ground potential. Figure 5 As shown, the fourth electrode 52B is provided on the lower surface of the film 521. The fourth electrode 52B covers the lower surface of the film 521. That is, the fourth main surface S6 is the lower surface of the fourth electrode 52B. The fourth electrode 52B is a metal film formed by vapor deposition, for example.

[0087] The charge amplifier 522 converts the charge generated by the thin film 521 into a voltage signal. After the conversion, the charge amplifier 522 outputs the voltage signal to the integration circuit 523.

[0088] The integrating circuit 523 integrates the voltage signal with respect to time, so that the second sensor 52 outputs a first detection signal indicating the relationship between the deformation amount of the film 521 and time.

[0089] In this embodiment, the second sensor 52 detects the force applied to the vibrated member 2 by detecting the deformation of the second elastic connecting member 332. Figure 3 As shown, the second sensor 52 is attached to the second elastic connecting member 332. Specifically, the third main surface S5 of the second sensor 52 is attached to the lower surface of the second elastic connecting member 332, for example, by means of an insulating adhesive material (not shown). Thus, in this embodiment, the second sensor 52 obtains a first detection signal representing the relationship between the deformation of the second elastic connecting member 332 and time. As a result, the second sensor 52 can detect the force applied to the vibrated member 2 by detecting the deformation of the second elastic connecting member 332.

[0090] [Effect]

[0091] The support device 20 can be used to prevent the vibration device that vibrates due to the user's pressure from being clamped between the electronic device body and the object being operated, thereby hindering the vibration of the vibration device. In more detail, the support device 20 includes a support portion 32. The support portion 32 overlaps with the vibrated component 2 when viewed in the up and down direction, and is located below the lower main surface S2 of the vibrated component 2. In addition, the actuator 4 is mounted on the support portion 32 and the vibrated component 2. As a result, the actuator 4 does not protrude from the vibrated component 2 when viewed in the up and down direction. Therefore, even if the pressure applied by the user 100 is large, the support device 20 can prevent the vibration of the actuator 4 from being hindered by being clamped between the vibrated component 2 and the support portion 31. As a result, the support device 20 can be used to prevent the vibration device that vibrates due to the user's pressure from being clamped between the electronic device body and the object being operated, thereby hindering the vibration of the vibration device.

[0092] The support device 20 can be used to support the support device 20 on the housing 1. In more detail, the support member 3 includes a supported portion 31. In addition, the supported portion 31 has a first portion P1 that does not overlap with the vibrated member 2 when viewed in the vertical direction. In addition, the first portion P1 is supported by the housing 1. Thus, the supported portion 31 is supported by the housing 1. Therefore, the support member 3 is supported by the housing 1. As a result, the support device 20 can be used to support the support device 20 on the housing 1.

[0093] By adopting the supporting device 20, the force applied to the vibrated member 2 can be detected without installing a sensor on the vibrated member 2. In more detail, the supporting member 3 includes an elastic connecting member 33 that elastically connects the vibrated member 2 and the supported portion 31. The elastic connecting member 33 deforms when a force is applied to the vibrated member 2. The sensor 5 is mounted on the elastic connecting member 33. The sensor 5 detects the force applied to the vibrated member 2. Specifically, the sensor 5 detects the force applied to the vibrated member 2 by detecting the deformation amount of the elastic connecting member 33. As a result, by adopting the supporting device 20, the force applied to the vibrated member 2 can be detected without installing a sensor on the vibrated member 2.

[0094] By adopting the support device 20, a sensor is not installed on the vibrated component 2, and the force applied to the vibrated component 2 can be detected with higher accuracy. In more detail, the material of the elastic connecting member 33 is metal or resin. In addition, the elastic connecting member 33 includes an elastic deformation portion P33 that elastically deforms. By installing the sensor 5 on the elastic deformation portion P33, it is easy to detect the deformation amount of the elastic connecting member 33, and the force applied to the vibrated component 2 can be detected with higher accuracy. As a result, by adopting the support device 20, a sensor is not installed on the vibrated component 2, and the force applied to the vibrated component 2 can be detected with higher accuracy.

[0095] By adopting the support device 20, a sensor is not installed on the vibrated component 2, and the force applied to the vibrated component 2 can be detected with higher accuracy. When the user 100 applies a force F to the vibrated component 2 in the up and down directions, the component of the deformation of the elastic connecting member 33 in the up and down directions is larger than the maximum value of the deformation of the vibrated component 2 in the direction perpendicular to the up and down directions. The sensor 5 detects the force applied to the vibrated component 2 by detecting the deformation of the elastic connecting member 33. Thus, by being installed on the elastic connecting member 33, the sensor 5 can detect the force applied to the vibrated component 2 with higher accuracy compared to when the sensor 5 is installed on the vibrated component 2. As a result, by adopting the support device 20, a sensor is not installed on the vibrated component 2, and the force applied to the vibrated component 2 can be detected with higher accuracy.

[0096] By adopting the supporting device 20, a sensor is not installed on the vibrated component 2, and the force applied to the vibrated component 2 can be detected with higher precision. In more detail, the upper main surface S1 or the lower main surface S2 of the vibrated component 2 has a rectangular shape when viewed in the up-down direction, and the rectangular shape has a front side, a rear side, a left side, and a right side. In addition, the elastic connecting member 33 overlaps with at least any one of the first corner formed by the front side and the left side, the second corner formed by the front side and the right side, the third corner formed by the rear side and the left side, and the fourth corner formed by the rear side and the right side when viewed in the up-down direction. Thus, when the elastic connecting member 33 overlaps with the first corner when viewed in the up-down direction, the sensor 5 can detect with high precision the force applied to the vibrated component 2 when the user 100 applies a force to the first corner of the vibrated component 2. Furthermore, when the elastic connecting member 33 overlaps with the second corner when viewed in the vertical direction, the sensor 5 can accurately detect the force applied to the vibrated member 2 when the user 100 applies a force to the second corner of the vibrated member 2. Furthermore, when the elastic connecting member 33 overlaps with the third corner when viewed in the vertical direction, the sensor 5 can accurately detect the force applied to the vibrated member 2 when the user 100 applies a force to the third corner of the vibrated member 2. Furthermore, when the elastic connecting member 33 overlaps with the fourth corner when viewed in the vertical direction, the sensor 5 can accurately detect the force applied to the vibrated member 2 when the user 100 applies a force to the fourth corner of the vibrated member 2. As a result, by using the support device 20, it is possible to detect the force applied to the vibrated member 2 with higher accuracy without installing a sensor on the vibrated member 2.

[0097] The support device 20 can stabilize the support of the vibrated member 2. More specifically, the support member 3 has a frame shape that surrounds the vibrated member 2 when viewed in the vertical direction. Thus, the support device 20 can support the outer periphery of the vibrated member 2 when viewed in the vertical direction. As a result, the support device 20 can stabilize the support of the vibrated member 2.

[0098] [Second embodiment]

[0099] Hereinafter, a support device 20a according to a second embodiment of the present invention will be described with reference to the drawings. Figure 6 It is a plan view of the housing 1 , the vibrated member 2 , the actuator 4 , and the support device 20 a according to the second embodiment, as viewed in a downward direction. Figure 7 This is a partial cross-sectional view of the housing portion 1a, the vibrated member 2, the supporting member 3, the sensor 5, and the buffer member 6 of the second embodiment as viewed from the front. In addition, with respect to the supporting device 20a of the second embodiment, only the parts that differ from the supporting device 20 of the first embodiment are described and omitted.

[0100] The support device 20a differs from the support device 20 in that the installation position of the support part 32 is different, the installation positions of the first elastic connecting structure 331, the second elastic connecting structure 332, the third elastic connecting structure 333 and the fourth elastic connecting structure 334 are different, the four elastic connecting structures 33 respectively include a second part P2 extending in the up and down directions, and the support device 20a also has four buffer members 6.

[0101] In this embodiment, the support portion 32 is located forward of the support portion 32 of the first embodiment. Therefore, the actuator 4 is located forward of the actuator 4 of the first embodiment. In this case, the actuator 4 also vibrates the vibrated member 2.

[0102] In this embodiment, the first elastic connecting member 331 protrudes backward from the front long side of the supported portion 31. Figure 6 As shown, the first elastic connecting member 331 overlaps with the midpoint of the front side of the upper main surface S1 when viewed in the vertical direction. In addition, the second elastic connecting member 332 protrudes forward from the rear long side of the supported portion 31. Figure 6 As shown, the second elastic connecting member 332 overlaps with the midpoint of the rear side of the upper main surface S1. In addition, the third elastic connecting member 333 protrudes from the left short side of the supported portion 31 to the right. Figure 6 As shown, the third elastic connecting member 333 overlaps with the midpoint of the left side of the upper main surface S1 when viewed in the vertical direction. In addition, the fourth elastic connecting member 334 protrudes from the right short side of the supported portion 31 to the left. Figure 6As shown, the fourth elastic connecting member 334 overlaps with the midpoint of the right side of the upper main surface S1 when viewed in the up-down direction.

[0103] like Figure 6 and Figure 7 As shown, the first elastic connecting member 331, the second elastic connecting member 332, the third elastic connecting member 333 and the fourth elastic connecting member 334 each include a second portion P2 extending in the vertical direction. In this embodiment, the second portion P2 is located above the elastic deformation portion P33. Figure 6 As shown, the second portion P2 has a rectangular shape when viewed in the up-down direction.

[0104] The four buffer members 6 are made of a material that is easily deformed when subjected to external force. For example, the four buffer members 6 are made of a foam material.

[0105] Here, the four buffer members 6 are respectively set as a first buffer member 61, a second buffer member 62, a third buffer member 63 and a fourth buffer member 64. In this embodiment, as Figure 6 As shown, the first buffer member 61 is attached to the first elastic connecting member 331. More specifically, the vibrated member 2, the first buffer member 61, and the second portion P2 of the first elastic connecting member 331 have portions located at the same vertical position. Furthermore, the first buffer member 61 is attached between the vibrated member 2 and the second portion P2 of the first elastic connecting member 331. Thus, the second portion P2 of the first elastic connecting member 331 supports the vibrated member 2 from the front via the first buffer member 61.

[0106] like Figure 6 As shown, the second buffer member 62 is attached to the second elastic connecting member 332. More specifically, the vibrated member 2, the second buffer member 62, and the second portion P2 of the second elastic connecting member 332 have portions located at the same vertical position. Furthermore, the second buffer member 62 is attached between the vibrated member 2 and the second portion P2 of the second elastic connecting member 332. Thus, the second portion P2 of the second elastic connecting member 332 supports the vibrated member 2 from the rear via the second buffer member 62.

[0107] like Figure 6 As shown in FIG. 3 , the third buffer member 63 is mounted on the third elastic connecting member 333. In more detail, as shown in FIG. Figure 7 As shown in FIG. 1 , the vibrated member 2, the third buffer member 63 and the second portion P2 of the third elastic connecting member 333 have portions located at the same position in the vertical direction. Figure 7As shown, the third buffer member 63 is installed between the vibrated member 2 and the second portion P2 of the third elastic connecting member 333. Thus, the second portion P2 of the third elastic connecting member 333 supports the vibrated member 2 from the left via the third buffer member 63.

[0108] like Figure 6 As shown, the fourth buffer member 64 is mounted on the fourth elastic connecting member 334. In more detail, as shown in FIG. Figure 7 As shown in FIG. 1 , the vibrated member 2, the fourth buffer member 64, and the second portion P2 of the fourth elastic connecting member 334 have portions located at the same position in the vertical direction. Figure 7 As shown, the fourth buffer member 64 is installed between the vibrated member 2 and the second portion P2 of the fourth elastic connecting member 334. Thus, the second portion P2 of the fourth elastic connecting member 334 supports the vibrated member 2 from the right via the fourth buffer member 64.

[0109] Using the support device 20a eliminates the need to attach a sensor to the vibrated member 2, allowing for more accurate detection of the force applied to the vibrated member 2. Specifically, the upper principal surface S1 or the lower principal surface S2 of the vibrated member 2 has a rectangular shape when viewed in the vertical direction, with the rectangular shape having a front side, a rear side, a left side, and a right side. Furthermore, the elastic connecting member 33 overlaps with at least one of the midpoints of the front side, the midpoint of the rear side, the midpoint of the left side, and the midpoint of the right side when viewed in the vertical direction. Thus, when the elastic connecting member 33 overlaps with the midpoint of the front side when viewed in the vertical direction, the sensor 5 can accurately detect the force applied to the vibrated member 2 when the user 100 applies a force to the front side of the upper principal surface S1 of the vibrated member 2. Furthermore, when the elastic connecting member 33 overlaps with the midpoint of the rear side when viewed in the vertical direction, the sensor 5 can accurately detect the force applied to the vibrated member 2 when the user 100 applies a force to the rear side of the upper principal surface S1 of the vibrated member 2. Furthermore, when the elastic connecting member 33 overlaps with the midpoint of the left side when viewed in the vertical direction, the sensor 5 can accurately detect the force applied to the vibrated member 2 when the user 100 applies a force to the left side of the upper main surface S1 of the vibrated member 2. Furthermore, when the elastic connecting member 33 overlaps with the midpoint of the right side when viewed in the vertical direction, the sensor 5 can accurately detect the force applied to the vibrated member 2 when the user 100 applies a force to the right side of the upper main surface S1 of the vibrated member 2. As a result, by using the support device 20, it is possible to detect the force applied to the vibrated member 2 with higher accuracy without installing a sensor on the vibrated member 2.

[0110] By adopting the supporting device 20a, the vibrated component 2 can be supported without hindering the vibration of the vibrated component 2. In more detail, the vibrated component 2, the buffer member 6 and the second part P2 of the elastic connecting member 33 have parts located at the same position in the up and down directions. In addition, the buffer member 6 is installed between the vibrated component 2 and the second part P2 of the elastic connecting member 33. Here, the buffer member 6 is made of a material that is easy to deform when subjected to external force. Therefore, the buffer member 6 does not hinder the vibration of the vibrated component 2. In addition, the second part P2 of the elastic connecting member 33 supports the vibrated component 2 with the help of the buffer member 6. As a result, by adopting the supporting device 20a, the vibrated component 2 can be supported without hindering the vibration of the vibrated component 2.

[0111] [Third embodiment]

[0112] Hereinafter, a support device 20b according to a third embodiment of the present invention will be described with reference to the drawings. Figure 8 1. This is a plan view of the housing 1, the vibrated member 2, the actuator 4, and the support device 20b according to the third embodiment as viewed from below.

[0113] The support device 20b differs from the support device 20a in the installation position of the support portion 32, the installation positions of the first elastic connecting member 331, the second elastic connecting member 332, the third elastic connecting member 333 and the fourth elastic connecting member 334, and the shape of the second portion P2.

[0114] In this embodiment, the support portion 32 is located at the same position as the support portion 32 of the first embodiment. Therefore, the mounting position of the actuator 4 is the same as that of the actuator 4 of the first embodiment.

[0115] In this embodiment, the first elastic connecting member 331 protrudes from the left front corner of the supported portion 31 toward the right rear direction. Figure 8 As shown, the first elastic connecting member 331 overlaps with the first corner formed by the front and left sides of the upper main surface S1 when viewed in the vertical direction. In addition, the second elastic connecting member 332 protrudes from the right front corner of the supported portion 31 to the left rear direction. Figure 8 As shown, the second elastic connecting member 332 overlaps with the second corner formed by the front and right sides of the upper main surface S1 when viewed in the vertical direction. In addition, the third elastic connecting member 333 protrudes from the left rear corner of the supported portion 31 to the right front direction. Figure 8As shown, the third elastic connecting member 333 overlaps with the third corner formed by the rear side and the left side of the upper main surface S1 when viewed in the vertical direction. In addition, the fourth elastic connecting member 334 protrudes from the right rear corner of the supported portion 31 to the left front direction. Figure 8 As shown, the fourth elastic connecting member 334 overlaps with the fourth corner formed by the rear edge and the right edge of the upper main surface S1 when viewed in the vertical direction. That is, the mounting positions of the first elastic connecting member 331, the second elastic connecting member 332, the third elastic connecting member 333, and the fourth elastic connecting member 334 are the same as the mounting positions of the first elastic connecting member 331, the second elastic connecting member 332, the third elastic connecting member 333, and the fourth elastic connecting member 334 in the first embodiment.

[0116] In this embodiment, if Figure 8 As shown in FIG. 1 , the second portion P2 has an L-shaped shape when viewed in the vertical direction. Figure 8 As shown, the second portion P2 of the first elastic connecting member 331 is located to the left and forward of the first corner. Furthermore, the second portion P2 of the first elastic connecting member 331 includes a portion located to the left of the first corner when viewed in the vertical direction and extending in the front-to-back direction. Furthermore, the second portion P2 of the first elastic connecting member 331 includes a portion located in front of the first corner when viewed in the vertical direction and extending in the left-to-right direction. Thus, the second portion P2 of the first elastic connecting member 331 supports the vibrated member 2 from the left and forward direction via the first buffer member 61.

[0117] In addition, if Figure 8 As shown, the second portion P2 of the second elastic connecting member 332 is located to the right and forward of the second corner. Furthermore, the second portion P2 of the second elastic connecting member 332 includes a portion located to the right of the second corner when viewed in the vertical direction and extending in the front-to-back direction. Furthermore, the second portion P2 of the second elastic connecting member 332 includes a portion located in front of the second corner when viewed in the vertical direction and extending in the left-to-right direction. Thus, the second portion P2 of the second elastic connecting member 332 supports the vibrated member 2 from the right and forward direction via the second cushioning member 62.

[0118] In addition, if Figure 8 As shown, the second portion P2 of the third elastic connecting member 333 is located to the left and rearward of the third corner. Furthermore, the second portion P2 of the third elastic connecting member 333 includes a portion located to the left of the third corner when viewed in the vertical direction and extending in the front-to-back direction. Furthermore, the second portion P2 of the third elastic connecting member 333 includes a portion located to the rear of the third corner when viewed in the vertical direction and extending in the left-to-right direction. Thus, the second portion P2 of the third elastic connecting member 333 supports the vibrated member 2 from the left and rearward via the third cushioning member 63.

[0119] In addition, if Figure 8 As shown, the second portion P2 of the fourth elastic connecting member 334 is located to the right and rearward of the fourth corner. Furthermore, the second portion P2 of the fourth elastic connecting member 334 includes a portion located to the right of the fourth corner when viewed in the vertical direction and extending in the front-to-back direction. Furthermore, the second portion P2 of the fourth elastic connecting member 334 includes a portion located to the rear of the fourth corner when viewed in the vertical direction and extending in the left-to-right direction. Thus, the second portion P2 of the fourth elastic connecting member 334 supports the vibrated member 2 from the right and rearward direction via the fourth cushioning member 64.

[0120] The support device 20b described above also exhibits the same effects as those of the support device 20a.

[0121] [Fourth embodiment]

[0122] Hereinafter, a support device 20c according to a fourth embodiment of the present invention will be described with reference to the drawings. Figure 9 1. This is a plan view of the housing 1, the vibrated member 2, the actuator 4, and the support device 20c according to the fourth embodiment, viewed downward.

[0123] The support device 20c differs from the support device 20a in that the mounting position of the support portion 32 and the mounting positions of the first elastic connecting member 331 , the second elastic connecting member 332 , the third elastic connecting member 333 , and the fourth elastic connecting member 334 are different.

[0124] In this embodiment, the support portion 32 is located at the same position as the support portion 32 of the first embodiment. Therefore, the mounting position of the actuator 4 is the same as that of the actuator 4 of the first embodiment. Figure 9 As shown, the vibration direction VD of the vibrated member 2 is the left-right direction. Thus, the left and right sides, when viewed in the vertical direction, intersect with the vibration direction VD of the vibrated member 2. On the other hand, the front and rear sides, when viewed in the vertical direction, do not intersect with the vibration direction VD of the vibrated member 2.

[0125] In this embodiment, the first elastic connecting member 331 protrudes from the left short side of the inner edge of the supporting member 3 to the right.

[0129] The support device 20 d differs from the support device 20 b in that the first elastic connecting member 331 is mounted at a different position and that the support device 20 d does not include the second elastic connecting member 332 , the second sensor 52 , and the second buffer member 62 .

[0130] In this embodiment, the first elastic connecting member 331 protrudes from the front long side of the inner edge of the supporting member 3 in the rear direction.

[0138] [First Modification]

[0139] Hereinafter, a support device 20f according to a first modified example of the present invention will be described with reference to the drawings. Figure 12 1 is a cross-sectional view of the housing 1, the vibrated member 2, the actuator 4, and the support device 20f according to the first modification, taken along line AA. Regarding the support device 20f according to the first modification, only the parts that differ from the support device 20 according to the first embodiment will be described, and the description will be omitted.

[0140] The support device 20 f differs from the support device 20 in the shape of the housing first portion 1 a , the position of the vibrated member 2 , and the inclusion of a fifth cushioning member 65 and a sixth cushioning member 66 .

[0141] In this embodiment, if Figure 12 As shown in FIG. 1 , the first portion 1a of the housing has a portion protruding downward from the lower surface of the first portion 1a of the housing. Figure 12 As shown in FIG. 1 , the first portion P1 of the supported portion 31 is attached to a portion that protrudes downward from the lower surface of the first portion 1 a of the housing 1 .

[0142] The first portion 1a of the housing overlaps the vibrated member 2 when viewed in the vertical direction. Figure 12As shown, the vertical position of the vibrated member 2 is lower than the vertical position of the housing first portion 1 a .

[0143] The fifth and sixth buffer members 65 and 66 are each made of a material that is easily deformed when receiving an external force. The fifth and sixth buffer members 65 and 66 are each made of a foam material, for example.

[0144] The fifth buffer member 65 overlaps the first housing portion 1a and the vibrated member 2 when viewed in the vertical direction. Figure 12 As shown, the fifth buffer member 65 is installed between the first portion 1a of the housing and the vibrated member 2.

[0145] The supporting device 20f as described above also exhibits the same effects as those of the supporting device 20b.

[0146] [Second Modification]

[0147] Hereinafter, a support device 20g according to a second modified example of the present invention will be described with reference to the drawings. Figure 13 1 is a plan view of the housing 1 , the vibrated member 2 , the actuator 4 , and the support device 20 g according to the second modification example, as seen in a downward direction. Figure 14 It is a cross-sectional view along CC of the housing 1, the vibrated member 2, the actuator 4, and the support device 20g of the second modification. Note that, regarding the support device 20g of the second modification, only the parts that differ from the support device 20f of the first modification will be described and omitted.

[0148] The support device 20 g differs from the support device 20 in that the support device 20 g does not include the sensor 5 , and the support member 3 does not include the four elastic connecting members 33 , but includes four fixing members 7 .

Figure 18 As shown, the plurality of ninth buffer members 83 overlap the vibrated member 2 when viewed in the vertical direction.

Figure 19 As shown, four spacers 10 are provided around the four fixing members 7. Each of the four spacers 10 has a cylindrical shape extending in the vertical direction. Each of the four spacers 10 is made of metal, for example.
