DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] [First embodiment] The support device 20 according to the first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of the housing 1, the vibrated member 2, the actuator 4, and the support device 20 according to the first embodiment taken along line AA. FIG. 2 is a plan view of the housing 1, the vibrated member 2, the actuator 4, and the support device 20 according to the first embodiment taken along line BB. FIG. 4 is a plan view of the second elastic connecting member 332 according to the first embodiment taken along line BB. FIG. 5 is a plan view and a cross-sectional view of the second sensor 52 according to the first embodiment in a state in which the second sensor 52 is deployed on a plane.

[0014] 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 member 2 extends. The left-right direction is the direction in which the long side of the upper main surface S1 of the vibrated member 2 extends. The left-right direction is perpendicular to the up-down direction. The front-rear direction is the direction in which the short side of the upper main surface S1 of the vibrated member 2 extends. The front-rear direction is perpendicular to the up-down direction and the left-right direction. Note that the up-down direction, the left-right direction and the front-rear direction in this embodiment do not have to match the up-down direction, the left-right direction and the front-rear direction when the support device 20 is in use.

[0015] 1, for example, the support device 20 is used in an actuator unit that vibrates the vibrated member 2 when the user 100 presses the vibrated member 2, thereby providing haptic feedback to the user 100. As a result, when the user 100 presses the vibrated member 2, the vibrated member 2 vibrates, allowing the user 100 to feel that he or she has pressed the vibrated member 2.

[0016] In this embodiment, the housing 1 is a box having a rectangular parallelepiped shape. As an example, the housing 1 includes a first housing part 1a, a second housing part 1b, and a third housing part 1c, as shown in FIG. 1. The first housing part 1a is the upper surface of the housing 1. The third housing part 1c is the lower surface of the housing 1. The second housing part 1b is a side surface of the housing 1. The second housing part 1b is located between the first housing part 1a and the third housing part 1c when viewed in the front-rear direction.

[0017] An opening OP is provided in the housing 1 as shown in Fig. 1 and Fig. 2. More specifically, the opening OP has a rectangular shape when viewed in the up-down direction as shown in Fig. 2. The opening OP penetrates the housing first part 1a in the up-down direction as shown in Fig. 1. As a result, the housing first part 1a has a rectangular frame shape as shown in Fig. 2.

[0018] In this embodiment, the vibrated member 2 has a plate shape as shown in FIG. 1 as an example. As a result, the vibrated member 2 has an upper main surface S1 and a lower main surface S2 aligned in the vertical direction. The upper main surface S1 is located on the lower main surface S2. In this embodiment, the upper main surface S1 and the lower main surface S2 are parallel to each other. In this embodiment, each of the upper main surface S1 and the lower main surface S2 has a rectangular shape when viewed in the vertical direction. In addition, each of the upper main surface S1 and the lower main surface S2 has a long side extending in the left-right direction and a short side extending in the front-rear direction. That is, the upper main surface S1 has a rectangular shape with 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 when viewed in the vertical direction. Additionally, 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.

[0019] In this embodiment, the vertical position of the vibrated member 2 is the same as the vertical position of the first housing part 1a. As shown in Figs. 1 and 2, the vibrated member 2 is located within the opening OP when viewed in the vertical direction. This allows the user 100 to touch the upper main surface S1 as shown in Fig. 1. That is, a part of the body of the user 100 comes into contact with the upper main surface S1. This allows the user 100 to apply force to the vibrated member 2. Also, the vibrated member 2 is not in contact with the housing 1.

[0020] In this embodiment, the actuator 4 includes a first film 41, a first electrode (not shown), and a second electrode (not shown). The actuator 4 has a film shape.

[0021] In this embodiment, the first film 41 includes a piezoelectric body. That is, the actuator 4 includes a piezoelectric body. The first film 41 has an upper surface and a lower surface. The first electrode is provided on the upper surface of the first film 41 (not shown). The second electrode is provided on the lower surface of the first film 41 (not shown). The first electrode and the second electrode are, for example, metal films formed by vapor deposition.

[0022] In this embodiment, the actuator 4 has a first main surface S3 and a second main surface S4, as shown in FIG. 1. The first main surface S3 is located on the second main surface S4. The first main surface S3 is the upper surface of the first electrode. The second main surface S4 is the lower surface of the second electrode. More specifically, each of the first main surface S3 and the second main surface S4 has a rectangular shape when viewed in the up-down direction. Each of the first main surface S3 and the second main surface S4 has a long side extending in the left-right direction and a short side extending in the front-rear direction. In this embodiment, the first main surface S3 and the second main surface S4 are parallel to each other. In addition, each of the upper main surface S1, the lower main surface S2, the first main surface S3 and the second main surface S4 are parallel to each other.

[0023] 1, the actuator 4 is attached to the lower main surface S2 of the vibrated member 2. That is, the actuator 4 is attached to the lower main surface S2 of the vibrated member 2. More specifically, in this embodiment, the actuator 4 is attached to the lower main surface S2 of the vibrated member 2 in a state in which it is slightly stretched in the left-right direction. The right end of the actuator 4 is attached to the lower main surface S2 of the vibrated member 2 via an adhesive (not shown).

[0024] As an example, the support device 20 includes a support member 3 and four sensors 5 as shown in FIG.

[0025] 2, the supporting member 3 includes a supported portion 31, a supporting portion 32, and four elastic connecting members 33. Also, as shown in FIG. 2, the supporting member 3 has a frame shape surrounding the vibrated member 2 when viewed in the up-down direction.

[0026] In this embodiment, the supported portion 31 has a rectangular frame shape when viewed in the up-down direction. The supported portion 31 has a front long side, a rear long side, a right short side, and a left short side. As shown in Figs. 1 and 3, 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 long side of the supported portion 31, and the right half of the right long side of the supported portion 31. The first portion P1 is located below the housing first portion 1a. And, the first portion P1 is supported by the housing 1 as shown in Figs. 1 and 3. More specifically, the first portion P1 is supported by the housing first portion 1a of the housing 1 as shown in Figs. 1 and 3. As a result, the supported portion 31 is supported by the housing 1.

[0027] The support part 32 is connected to the supported part 31 as shown in FIG. 1. More specifically, the support part 32 protrudes rightward from the left short side of the inner edge of the support member 3. As a result, the support part 32 overlaps with the vibrated member 2 when viewed in the up-down direction as shown in FIG. 2. Also, the support part 32 is located below the lower main surface S2 of the vibrated member 2 as shown in FIG. 1. The actuator 4 is attached to the support part 32 as shown in FIG. 1. Specifically, the left end part of the actuator 4 is attached to the upper surface of the support part 32 via an adhesive (not shown). As described above, the support part 32 supports the actuator 4.

[0028] In this embodiment, the actuator 4 expands and contracts in the left-right direction when an AC voltage is applied to the actuator 4. More specifically, the first film 41 expands and contracts in the left-right direction when a voltage is applied to the first electrode and the second electrode. For example, the actuator 4 expands in the left-right direction when a positive voltage is applied to the actuator 4. On the other hand, the actuator 4 contracts in the left-right direction when a negative voltage is applied to the actuator 4. That is, the actuator 4 vibrates in the left-right direction when an AC voltage is applied to the actuator 4. As a result, the actuator 4 vibrates the vibrated member 2. Therefore, in this embodiment, the vibrated member 2 vibrates in the left-right direction. The AC voltage is a voltage that periodically changes between positive and negative.

[0029] The vibrated member 2 is supported by the housing 1 via a support member 3. More specifically, the vibrated member 2 is elastically connected to the housing 1 via four elastic connecting members 33. This allows the vibrated member 2 to vibrate in any direction relative to the housing 1. The any direction may be the up-down direction, the left-right direction, the front-rear direction, or the like.

[0030] Here, the four elastic connecting members 33 are respectively referred to 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, the first elastic connecting member 331 overlaps with a first corner portion formed by the front side and the left side of the upper main surface S1 when viewed in the vertical direction, as shown in FIG. 2. Also, the second elastic connecting member 332 overlaps with a second corner portion formed by the front side and the right side of the upper main surface S1 when viewed in the vertical direction, as shown in FIG. 2. Also, the third elastic connecting member 333 overlaps with a third corner portion formed by the rear side and the left side of the upper main surface S1 when viewed in the vertical direction, as shown in FIG. 2. Also, the fourth elastic connecting member 334 overlaps with a fourth corner portion formed by the rear side and the right side of the upper main surface S1 when viewed in the vertical direction, as shown in FIG. 2.

[0031] The first elastic connecting member 331 has a structure that is symmetrical with the second elastic connecting member 332. The third elastic connecting member 333 has a structure that is point-symmetrical with the second elastic connecting member 332. The fourth elastic connecting member 334 has a structure that is symmetrical with the second elastic connecting member 332. Therefore, the following description will focus on the second elastic connecting member 332, and descriptions of the first elastic connecting member 331, the third elastic connecting member 333, and the fourth elastic connecting member 334 will be omitted.

[0032] 3, the second elastic connecting member 332 is attached to the supported portion 31. The second elastic connecting member 332 protrudes from the right front corner of the supported portion 31 in the left rear direction. The left rear end of the second elastic connecting member 332 is fixed to the vibrated member 2. As a result, 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.

[0033] The second elastic connecting member 332 elastically connects the vibrated member 2 and the supported portion 31. More specifically, 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 is elastically deformed. More specifically, the second elastic connecting member 332 includes an elastically deforming portion P33 that is elastically deformed as shown in FIG. 4. The elastic deformation of the elastic deformation portion P33 causes the second elastic connecting member 332 to be elastically deformed. 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 to the vibrated member 2 in the vertical direction, the vertical component of the deformation amount of the second elastic connecting member 332 is greater than the maximum value of the deformation amount in the direction perpendicular to the vertical direction of the vibrated member 2.

[0034] Here, the four sensors 5 are respectively referred to as a first sensor 51, a second sensor 52, a third sensor 53, and a fourth sensor 54. In this embodiment, the first sensor 51 is attached to the first elastic connecting member 331 as shown in FIG. 2. The second sensor 52 is attached to the second elastic connecting member 332 as shown in FIG. 2. The third sensor 53 is attached to the third elastic connecting member 333 as shown in FIG. 2. The fourth sensor 54 is attached to the fourth elastic connecting member 334 as shown in FIG. 2. That is, the sensor 5 is attached to the elastic connecting member 33. Note that the sensor 5 may be attached to at least 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.

[0035] The first sensor 51 has a structure symmetrical with the second sensor 52. The third sensor 53 has a structure symmetrical with respect to a point with the second sensor 52. The fourth sensor 54 has a structure symmetrical with respect to the front and rear with respect to the second sensor 52. Therefore, the following description will focus on the second sensor 52, and descriptions of the first sensor 51, the third sensor 53, and the fourth sensor 54 will be omitted.

[0036] The second sensor 52 is a sensor that detects a force applied to the vibrated member 2. In this embodiment, as shown in Fig. 5, the second sensor 52 includes a 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 film shape.

[0037] As shown in FIG. 5, the second sensor 52 has a third main surface S5 and a fourth main surface S6. Each of the third main surface S5 and the fourth main surface S6 has a rectangular shape when viewed in the up-down direction when the second sensor 52 is developed on a plane. Each of the third main surface S5 and the fourth main surface S6 has a long side extending in the left-right direction and a short side extending in the front-rear direction when the second sensor 52 is developed on a plane. In this embodiment, the third main surface S5 and the fourth main surface S6 are parallel to each other. In addition, the third main surface S5 is located on the fourth main surface S6.

[0038] 5, the film 521 has an upper surface and a lower surface. In this embodiment, the film 521 includes a piezoelectric body. That is, the second sensor 52 includes a piezoelectric body. The film 521 is a piezoelectric film. More specifically, in this embodiment, the film 521 is a PLLA film.

[0039] The film 521 generates electric charges according to the differential value of the displacement of the film 521. The film 521 has a characteristic that the polarity of the electric charges generated when the film 521 is stretched in the left-right direction is opposite to the polarity of the electric charges 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 the chiral polymer is polylactic acid (PLA), particularly L-type polylactic acid (PLLA). PLLA, which is made of a chiral polymer, has a helical main chain structure. PLLA has piezoelectricity in which the molecules are oriented by uniaxial stretching. The film 521 has a piezoelectric constant of d14.

[0040] In this embodiment, the uniaxial stretching axis OD of the film 521 forms an angle of 45 degrees counterclockwise with respect to the left-right direction and an angle of 45 degrees clockwise with respect to the front-rear direction. That is, the film 521 is stretched at least in a uniaxial direction. This 45 degrees includes, for example, an angle of about 45 degrees ±10 degrees. As a result, the film 521 generates electric charges when the film 521 is deformed so as to be expanded in the left-right direction or compressed in the left-right direction. For example, the film 521 generates positive electric charges when it is deformed so as to be expanded in the left-right direction. For example, the film 521 generates negative electric charges when it is deformed so as to be compressed in the left-right direction. The magnitude of the generated electric charges depends on the differential value of the displacement of the film 521 due to the expansion or compression.

[0041] The third electrode 52F is a signal electrode. As shown in Fig. 5, 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. In other words, the third main surface S5 is the upper surface of the third electrode 52F. The third electrode 52F is, for example, a metal coating formed by vapor deposition.

[0042] The fourth electrode 52B is a ground electrode. The fourth electrode 52B is connected to a ground potential. The fourth electrode 52B is provided on the lower surface of the film 521 as shown in FIG. 5. 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, for example, a metal coating formed by vapor deposition.

[0043] The charge amplifier 522 converts the charge generated by the film 521 into a voltage signal. After conversion, the charge amplifier 522 outputs the voltage signal to the integration circuit 523.

[0044] Integration circuit 523 integrates the voltage signal over time, causing second sensor 52 to output a first detection signal indicating the relationship between the amount of deformation of film 521 and time.

[0045] In this embodiment, the second sensor 52 detects the force applied to the vibrated member 2 by detecting the deformation amount of the second elastic connecting member 332. More specifically, the second sensor 52 is attached to the second elastic connecting member 332 as shown in FIG. 3. 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, via an insulating adhesive (not shown). Thereby, in this embodiment, the second sensor 52 obtains a first detection signal indicating the relationship between the deformation amount 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 amount of the second elastic connecting member 332.

[0046] [effect] According to the support device 20, the vibration device that generates vibrations is sandwiched between the electronic device body and the operation target object by the user's pressure, and the vibration of the vibration device can be prevented from being hindered. More specifically, the support device 20 includes a support part 32. The support part 32 overlaps with the vibrated member 2 when viewed in the vertical direction, and is located below the lower main surface S2 of the vibrated member 2. The actuator 4 is attached to the support part 32 and the vibrated member 2. As a result, the actuator 4 does not protrude from the vibrated member 2 when viewed in the vertical direction. Therefore, even if the user 100 applies a large pressure, the support device 20 can prevent the actuator 4 from being sandwiched between the vibrated member 2 and the supported part 31, and thus the vibration of the actuator 4 is hindered. As a result, according to the support device 20, the vibration device that generates vibrations is sandwiched between the electronic device body and the operation target object by the user's pressure, and the vibration of the vibration device can be prevented from being hindered.

[0047] The support device 20 can be supported on the housing 1. More specifically, the support member 3 includes a supported portion 31. 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 supported on the housing 1. This allows the supported portion 31 to be supported on the housing 1. Therefore, the support member 3 is supported on the housing 1. As a result, the support device 20 can be supported on the housing 1.

[0048] The support device 20 can detect the force applied to the vibrated member 2 without attaching a sensor to the vibrated member 2. More specifically, the support 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 attached to 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 amount of deformation of the elastic connecting member 33. As a result, the support device 20 can detect the force applied to the vibrated member 2 without attaching a sensor to the vibrated member 2.

[0049] The support device 20 makes it possible to detect the force applied to the vibrated member 2 with high accuracy without attaching a sensor to the vibrated member 2. More specifically, the material of the elastic connecting member 33 is metal or resin. The elastic connecting member 33 includes an elastic deformation portion P33 that elastically deforms. By attaching the sensor 5 to the elastic deformation portion P33, it becomes easier to detect the amount of deformation of the elastic connecting member 33, and the force applied to the vibrated member 2 can be detected with high accuracy. As a result, the support device 20 makes it possible to detect the force applied to the vibrated member 2 with high accuracy without attaching a sensor to the vibrated member 2.

[0050] The support device 20 can detect the force applied to the vibrated member 2 with higher accuracy without attaching a sensor to the vibrated member 2. When the user 100 applies a force F in the vertical direction to the vibrated member 2, the vertical component of the deformation amount of the elastic connecting member 33 is greater than the maximum deformation amount in the direction perpendicular to the vertical direction of the vibrated member 2. The sensor 5 detects the deformation amount of the elastic connecting member 33 to detect the force applied to the vibrated member 2. As a result, the sensor 5 is attached to the elastic connecting member 33, and can detect the force applied to the vibrated member 2 with higher accuracy than if the sensor 5 were attached to the vibrated member 2. As a result, the support device 20 can detect the force applied to the vibrated member 2 with higher accuracy without attaching a sensor to the vibrated member 2.

[0051] The support device 20 can detect the force applied to the vibrated member 2 with high accuracy without attaching a sensor to the vibrated member 2. More specifically, the upper main surface S1 or the lower main surface S2 of the vibrated member 2 has a rectangular shape having a front side, a rear side, a left side, and a right side when viewed in the vertical direction. In addition, the elastic connecting member 33 overlaps at least one of a first corner portion formed by the front side and the left side, a second corner portion formed by the front side and the right side, a third corner portion formed by the rear side and the left side, or a fourth corner portion formed by the rear side and the right side when viewed in the vertical direction. As a result, when the elastic connecting member 33 overlaps the first corner portion when viewed in the vertical direction, the sensor 5 can detect the force applied to the vibrated member 2 with high accuracy when the user 100 applies force to the first corner portion of the vibrated member 2. Furthermore, when the elastic connecting member 33 overlaps with the second corner portion when viewed in the vertical direction, the sensor 5 can detect with high accuracy the force applied to the vibrated member 2 when the user 100 applies force to the second corner portion of the vibrated member 2. Furthermore, when the elastic connecting member 33 overlaps with the third corner portion when viewed in the vertical direction, the sensor 5 can detect with high accuracy the force applied to the vibrated member 2 when the user 100 applies force to the third corner portion of the vibrated member 2. Furthermore, when the elastic connecting member 33 overlaps with the fourth corner portion when viewed in the vertical direction, the sensor 5 can detect with high accuracy the force applied to the vibrated member 2 when the user 100 applies force to the fourth corner portion of the vibrated member 2. As a result, the support device 20 can detect the force applied to the vibrated member 2 with high accuracy without attaching a sensor to the vibrated member 2.

[0052] The support device 20 can stably support the vibrated member 2. More specifically, the support member 3 has a frame shape surrounding the vibrated member 2 when viewed in the vertical direction. This allows the support device 20 to support the outer periphery of the vibrated member 2 when viewed in the vertical direction. As a result, the support device 20 can stably support the vibrated member 2.

In this embodiment, the second portion P2 is located above the elastic deformation portion P33. Also, the second portion P2 has a rectangular shape when viewed in the up-down direction, as shown in Fig. 6.

[0058] Each of the four cushion members 6 is made of a material that is easily deformed when subjected to an external force, for example, a foam material.

[0059] Here, the four cushion members 6 are respectively a first cushion member 61, a second cushion member 62, a third cushion member 63, and a fourth cushion member 64. In this embodiment, the first cushion member 61 is attached to the first elastic connecting member 331 as shown in FIG. 6. More specifically, the vibrated member 2, the first cushion member 61, and the second portion P2 of the first elastic connecting member 331 have portions located at the same position in the up-down direction. In addition, the first cushion member 61 is attached between the vibrated member 2 and the second portion P2 of the first elastic connecting member 331.

Furthermore, the third cushion member 63 is attached between the vibrated member 2 and the second portion P2 of the third elastic connecting member 333 as shown in Fig. 7. As a result, the second portion P2 of the third elastic connecting member 333 supports the vibrated member 2 from the left direction via the third cushion member 63.

[0062] The fourth cushion member 64 is attached to the fourth elastic connecting member 334 as shown in Fig. 6. More specifically, the vibrated member 2, the fourth cushion member 64, and the second portion P2 of the fourth elastic connecting member 334 have portions located at the same position in the up-down direction as shown in Fig. 7. Furthermore, the fourth cushion member 64 is attached between the vibrated member 2 and the second portion P2 of the fourth elastic connecting member 334 as shown in Fig. 7. As a result, the second portion P2 of the fourth elastic connecting member 334 supports the vibrated member 2 from the right direction via the fourth cushion member 64.

[0063] According to the support device 20a, it is possible to detect the force applied to the vibrated member 2 with high accuracy without attaching a sensor to the vibrated member 2. More specifically, the upper main surface S1 or the lower main surface S2 of the vibrated member 2 has a rectangular shape having a front side, a rear side, a left side, and a right side when viewed in the vertical direction. Moreover, the elastic connecting member 33 overlaps with at least one of the midpoint of the front side, the midpoint of the rear side, the midpoint of the left side, or the right side when viewed in the vertical direction. As a result, when the elastic connecting member 33 overlaps with the midpoint of the front side when viewed in the vertical direction, the sensor 5 can detect with high accuracy the force applied to the vibrated member 2 when the user 100 applies force to the front side of the upper main surface S1 of the vibrated member 2. Moreover, when the elastic connecting member 33 overlaps with the midpoint of the rear side when viewed in the vertical direction, the sensor 5 can detect with high accuracy the force applied to the vibrated member 2 when the user 100 applies force to the rear 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 left side when viewed in the vertical direction, the sensor 5 can detect with high accuracy the force applied to the vibrated member 2 when the user 100 applies 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 detect with high accuracy the force applied to the vibrated member 2 when the user 100 applies force to the right side of the upper main surface S1 of the vibrated member 2. As a result, the support device 20 can detect the force applied to the vibrated member 2 with high accuracy without attaching a sensor to the vibrated member 2.

[0064] The support device 20a can support the vibrated member 2 without hindering the vibration of the vibrated member 2. More specifically, the vibrated member 2, the cushion member 6, and the second part P2 of the elastic connecting member 33 have parts located at the same position in the vertical direction. The cushion member 6 is attached between the vibrated member 2 and the second part P2 of the elastic connecting member 33. Here, the cushion member 6 is made of a material that is easily deformed when subjected to an external force. As a result, the cushion member 6 does not hinder the vibration of the vibrated member 2. The second part P2 of the elastic connecting member 33 supports the vibrated member 2 via the cushion member 6. As a result, the support device 20a can support the vibrated member 2 without hindering the vibration of the vibrated member 2.
