Detailed Description

Embodiments according to the present disclosure will be described below with reference to the drawings. Hereinafter, the same reference numerals are given to the components shared in the drawings. The drawings used in the following description are only schematic drawings. The dimensional ratio and the like in the drawings do not necessarily coincide with the actual dimensional ratio.

[ example of Structure of tactile sensation presenting device ]

Fig. 1 is an external view of a tactile sensation presentation device 1 incorporating a module 4 according to an embodiment of the present disclosure. Fig. 2 is an exploded perspective view of the range R shown in fig. 1. As shown in fig. 1, the tactile sensation presentation device 1 is a rectangular parallelepiped shape in appearance. Hereinafter, in fig. 1 and 2, the thickness direction of the tactile sensation presentation device 1 is referred to as the X-axis direction. The longitudinal direction of the tactile sensation presentation device 1 is set as the Y-axis direction. The short side direction of the tactile sensation presentation device 1 is set as the Z-axis direction.

The tactile sensation presentation apparatus 1 is provided with a vibration object 2, a housing 3, and 4 components 4. Here, the number of the components 4 included in the tactile sensation presentation device 1 is not limited to 4. The number of the units 4 included in the tactile sensation presentation device 1 may be 3 or less, or 5 or more.

The tactile sensation presentation device 1 presents a tactile sensation to a user who touches the main surface 2a of the vibration object 2 by vibrating the vibration object 2. Examples of the tactile sensation presenting apparatus 1 include a car navigation system, and a car-mounted device such as a steering system or a switch of a power window. Examples of the tactile sensation presentation apparatus 1 include a mobile phone, a smartphone, a tablet PC (personal computer), and a notebook PC. However, the tactile sensation presenting apparatus 1 is not limited to these. The tactile sensation presenting apparatus 1 may be a desktop PC, a home appliance, an industrial equipment (fa (factory automation) equipment), a dedicated terminal, various electronic equipments, or the like.

The vibrating object 2 has a main surface 2 a. The user touches the main surface 2a with a finger or the like. The vibration object 2 may be a touch sensor disposed in the display panel. Wherein the vibration object 2 is not limited to a touch sensor. For example, the vibrating object 2 may be a switch. The vibration of the component 4 is transmitted to the vibrating object 2. The vibration object 2 vibrates by the transmission of the vibration of the package 4.

The vibration direction of the vibration target 2 includes, for example, an in-plane direction and an out-of-plane direction. The in-plane direction is a direction substantially parallel to the main surface 2a of the vibration object 2. For example, in fig. 1, the in-plane direction is a direction parallel to the ZY plane. Therefore, in fig. 1, the in-plane vibration is, for example, a Z-axis vibration. The out-of-plane direction is a direction perpendicular to the main surface 2a of the vibrating object 2. Therefore, in fig. 1, the vibration in the out-of-plane direction is the vibration in the X-axis direction. Hereinafter, the vibration in the in-plane direction is also referred to as "lateral vibration". The vibration in the out-of-plane direction is also referred to as "longitudinal vibration".

By appropriately selecting the component 4 incorporated in the tactile sensation presenting apparatus 1, the vibration direction of the vibration object 2 can be set. For example, when the vibration direction of the vibration target 2 is set to the in-plane direction, in other words, when the vibration target 2 is intended to be vibrated laterally, the module 4 shown in fig. 3 described later or the module 104 shown in fig. 6 described later can be selected. For example, when the vibration direction of the vibration target 2 is set to the out-of-plane direction, in other words, when the vibration target 2 is intended to vibrate longitudinally, the element 204 shown in fig. 8 described later may be selected.

the vibration direction of the vibration object 2 may be appropriately set according to the use of the tactile sensation presentation apparatus 1 or the like. For example, when the tactile sensation presentation apparatus 1 is an in-vehicle device, the vibration object 2 can be a display unit of a car navigation system. Further, the traveling direction of the vehicle on which the tactile sensation presenting device 1 is mounted can be almost the X-axis direction. In this case, the vibration direction of the vibration object 2 may be set to the in-plane direction.

The housing 3 may be formed of metal, synthetic resin, or the like. The housing 3 protects the internal structure of the tactile sensation presentation device 1. The components 4, controller, memory, and the like may be housed in the case 3. The controller may be constituted by a processor or a microcomputer or the like capable of executing application software. The controller is connected to the assembly 4. The controller outputs a drive signal for vibrating the component 4 to the component 4. The drive signal may be a voltage signal or a current signal. The memory may be constituted by a semiconductor memory, a magnetic memory, or the like. The memory stores various information, a program for operating the controller, and the like. The controller and the memory may be provided outside the housing 3.

As shown in fig. 2, the component 4 is incorporated as one part in the tactile sensation presenting apparatus 1. The package 4 is disposed between the vibration target 2 and the bottom surface of the housing 3. The arrangement position of the components 4 can be appropriately determined according to the size of the vibration object 2. For example, in the case where the vibration target 2 is rectangular as shown in fig. 1, 4 units 4 may be arranged at four corners of the vibration target 2 as shown in fig. 1.

The component 4 vibrates according to a voltage signal output from the controller of the tactile sensation presentation apparatus 1. The vibration of the component 4 is transmitted to the vibration object 2 of the tactile sensation presenting apparatus 1.

[ structural example of Assembly ]

Fig. 3 is a front view of the assembly 4 according to an embodiment of the present disclosure. Fig. 4 is a perspective view of the assembly 4 shown in fig. 3. When the vibration direction of the vibration target 2 shown in fig. 1 is set to an in-plane direction, in other words, when the vibration target 2 is intended to be vibrated laterally, the component 4 can be selected.

as shown in fig. 3, the unit 4 includes an actuator 10, a first fixing portion 20, a second fixing portion 30, and elastic portions 40A and 40B. The assembly 4 may further be provided with a base 50.

The actuator 10 converts a voltage signal output from the controller of the tactile sensation presentation device 1 shown in fig. 1 into vibration. As shown in fig. 3, the actuator 10 includes a piezoelectric element 11, a vibration plate 12, support portions 13A and 13B, and bases 14A and 14B. The diaphragm 12, the support portions 13A and 13B, and the bases 14A and 14B may be formed integrally by bending a single thin plate, for example. Alternatively, diaphragm 12, support portions 13A and 13B, and bases 14A and 14B may be formed as separate bodies. When diaphragm 12, support portions 13A, 13B, and bases 14A, 14B are formed as separate bodies, diaphragm 12, support portions 13A, 13B, and bases 14A, 14B may be integrated by welding or the like.

The piezoelectric element 11 is, for example, rectangular. The voltage signal output by the controller of the tactile sensation presentation device 1 shown in fig. 1 described above is applied to the piezoelectric element 11. The piezoelectric element 11 expands and contracts in the longitudinal direction in response to an applied voltage signal, and is displaced. The piezoelectric element 11 may be a piezoelectric thin film or a piezoelectric ceramic. The piezoelectric ceramic can generate vibration having a large vibration energy as compared with a piezoelectric thin film.

The piezoelectric element 11 may be replaced with a magnetostrictive element. The magnetostrictive element expands and contracts in accordance with an applied magnetic field. When the piezoelectric element 11 is replaced with a magnetostrictive element, the module 4 may further include a coil or the like for converting the drive signal output from the controller into a magnetic field.

The vibrating plate 12 is a thin plate having elasticity such as a pad plate. The vibrating plate 12 may be a plate-shaped member having a predetermined thickness. The vibrating plate 12 may be formed of metal, resin, or a composite material of metal and resin. Hereinafter, a surface facing the base 50 out of the two surfaces included in the vibrating plate 12 is referred to as a "main surface 12 a". Of the two surfaces included in the vibrating plate 12, the surface facing the second fixing portion 30 is referred to as a "main surface 12 b".

The piezoelectric element 11 is provided on the main surface 12 a. The piezoelectric element 11 is provided on the main surface 12a such that the longitudinal direction of the piezoelectric element 11 coincides with the longitudinal direction of the vibration plate 12. The piezoelectric element 11 may be bonded to the main surface 12a with an adhesive or the like.

The structure in which the piezoelectric element 11 is provided on the main surface 12a, that is, the structure in which the piezoelectric element 11 is provided on one surface of the vibrating plate 12 is a so-called single crystal (unimorph). In the single crystal, the expansion and contraction displacement of the piezoelectric element 11 causes the bending vibration of the vibration plate 12. As shown in fig. 3, one end of the vibration plate 12 is supported by the support portion 13A. The other end portion of the vibration plate 12 is supported by the support portion 13B. When both ends of diaphragm 12 are supported in this way, diaphragm 12 vibrates such that the amplitude of diaphragm 12 in the normal direction of main surface 12a near the center of diaphragm 12 is maximized.

The component 4 is incorporated in the tactile sensation presenting apparatus 1 shown in fig. 1 described above such that the principal surface 12a is substantially parallel to the XY plane shown in fig. 2 described above. The main surface 12a is substantially parallel to the XY plane shown in fig. 2, so that the normal direction of the main surface 12a can correspond to the Z-axis direction shown in fig. 2. With the above-described configuration, the vibration object 2 shown in fig. 1 can be vibrated in the Z-axis direction by the vibration in the normal direction of the main surface 12 a. In other words, the package 4 causes the vibration target 2 shown in fig. 1 to vibrate laterally according to the expansion and contraction displacement of the piezoelectric element 11.

As shown in fig. 3, the support portion 13A is provided at one end in the longitudinal direction of the diaphragm 12. One end of the support portion 13A is connected to the vibration plate 12. The other end of the support portion 13A is connected to the base portion 14A. As shown in fig. 3, the support portion 13B is provided at the other end portion in the longitudinal direction of the vibration plate 12. One end of the support portion 13B is connected to the vibration plate 12. The other end of the support portion 13B is connected to the base portion 14B.

The support portions 13A, 13B support the vibration plate 12 so that a gap is generated between the piezoelectric element 11 and the base 50. By generating a gap between the piezoelectric element 11 and the base 50, when the vibration plate 12 vibrates in accordance with the displacement of the piezoelectric element 11, the piezoelectric element 11 can be prevented from colliding with the base 50. Support portions 13A and 13B may be formed of the same material as diaphragm 12 or a different material from diaphragm 12.

As shown in fig. 3, the base portion 14A is fixed to one end portion of the base portion 50. As shown in fig. 3, the base portion 14B is fixed to the other end portion of the base portion 50. The base portions 14A and 14B may be fixed between the first fixing portion 20 and the base portion 50 by a coupling member such as a screw or an adhesive, for example. Base portions 14A and 14B may be formed of the same material as diaphragm 12, or may be formed of a material different from diaphragm 12.

the first fixing portion 20 can be fixed to a base of the tactile sensation presenting apparatus 1 shown in fig. 1, for example, a bottom surface of the housing 3 shown in fig. 2. The first fixing portion 20 may be formed of metal, resin, or a composite material of metal and resin. As shown in fig. 3, the first fixing portion 20 includes a main body 21 and leg portions 22A and 22B. The first fixing portion 20 may further have through holes 23A, 23B.

A leg 22A is provided at one end of the body 21. Leg 22B is provided at the other end of body 21. For example, when the first fixing portion 20 does not have the through holes 23A and 23B, the main body portion 21 may be fixed to the bottom surface of the housing 3 shown in fig. 2 by an adhesive or the like.

The foot 22A is fixed to one end of the base 50. The base portion 14A of the actuator 10 is interposed between the foot portion 22A and the base portion 50. The leg portion 22B is fixed to the other end portion of the base portion 50. The base 14B of the actuator 10 is interposed between the foot 22B and the base 50.

The legs 22A and 22B may be fixed to the base 50 by a coupling member such as a screw or an adhesive, for example. For example, when the first fixing portion 20 does not have the through holes 23A and 23B, the legs 22A and 22B may be fixed to the bottom surface of the housing 3 shown in fig. 2 by an adhesive or the like.

The through hole 23A is provided in the leg 22A. The through hole 23B is provided in the leg 22B. As shown in fig. 2, the connecting member 5 such as a screw is inserted into the through holes 23A and 23B. The first fixing portion 20 is fixed to the bottom surface of the housing 3 by inserting the coupling member 5 into the through holes 23A and 23B.

The second fixing portion 30 can be fixed to the vibrating object 2 shown in fig. 2. The second fixing portion 30 may be formed of metal, resin, or a composite material of metal and resin. As shown in fig. 3, the second fixing portion 30 has a main body portion 31 and an engaging portion 32. The second fixing portion 30 may further have a through hole 33.

In a state where the unit 4 is incorporated in the tactile sensation presentation apparatus 1 shown in fig. 1, the main body portion 31 is in contact with the vibrating object 2 shown in fig. 2. In this state, the vibration target 2 may not be in contact with the first fixing portion 20. The body portion 31 transmits the vibration of the vibrating plate 12 to the vibrating object 2 shown in fig. 2 described above. For example, when the second fixing portion 30 does not have the through hole 33, the main body portion 31 may be fixed to the vibrating object 2 shown in fig. 2 by an adhesive or the like.

The bonding portion 32 is bonded to the vicinity of the center of the main surface 12b of the vibration plate 12. When the joint portion 32 is joined to the main surface 12b, the vibration of the vibrating plate 12 is transmitted to the main body portion 31 and to the vibrating object 2 shown in fig. 2.

As shown in fig. 2, the coupling member 5 such as a screw is inserted into the through hole 33. The second fixing portion 30 is fixed to the vibration target 2 by inserting the coupling member 5 into the through hole 33.

The elastic portions 40A and 40B connect the first fixing portion 20 and the second fixing portion 30. For example, the elastic portion 40A connects the leg portion 22A of the first fixing portion 20 and the body portion 31 of the second fixing portion 30. For example, the elastic portion 40B connects the leg portion 22B of the first fixing portion 20 and the body portion 31 of the second fixing portion 30. The elastic portions 40A and 40B may be leaf springs.

The base portion 14A of the actuator 10 and the leg portion 22A of the first fixing portion 20 are fixed to one end portion of the base portion 50. The base portion 14B of the actuator 10 and the leg portion 22B of the first fixing portion 20 are fixed to the other end portion of the base portion 50. The base 50 may be formed of metal, resin, or a composite material of metal and resin.

< comparative example >

Fig. 5 is an exploded perspective view of a tactile sensation presentation device 1X according to a comparative example. Fig. 5 corresponds to fig. 2 described above. Instead of the assembly 4 described above, the actuator 10X and the elastic portion 40X are directly incorporated into the tactile sensation presenting apparatus 1X according to the comparative example.

The actuator 10X includes a piezoelectric element 11, a vibrating plate 12, a support portion 13X, a base portion 14X, and a holding portion 15X.

One end of the support portion 13X is connected to the vibrating plate 12. The other end of the support portion 13X is connected to the base portion 14X.

The base portion 14X is fixed to the housing 3. Base 14X may have a hole 16X. The base portion 14X can be fixed to the housing 3 by inserting a coupling member such as a screw into the hole 16X. The base portion 14X may be fixed to the housing 3 by an adhesive or the like.

The holding portion 15X is provided on a surface facing the vibration object 2, out of the two surfaces of the vibration plate 12. The holding portion 15X is joined to the vibration target 2 with an adhesive or the like. The holding portion 15X is joined to the vibration object 2, whereby the vibration of the vibration plate 12 is transmitted to the vibration object 2.

The elastic portion 40X is a coil spring. At least 4 elastic portions 40X are arranged at four corners of the tactile sensation presenting device 1X. The elastic portion 40X is connected between the vibration target 2 and the housing 3. For example, one end of the elastic portion 40X is connected to the vibration target 2. The other end of the elastic portion 40X is connected to the bottom surface of the housing 3. At least 4 elastic portions 40X are connected between the vibration object 2 and the housing 3 at four corners of the tactile sensation presentation device 1X, respectively, whereby the vibration object 2 can be displaced with respect to the housing 3. In other words, the vibration object 2 can be vibrated by the vibration transmitted from the vibration plate 12 via the holding portion 15X.

As described above, in the tactile sensation presentation apparatus 1X according to the comparative example, the plurality of elastic portions 40X, the actuator 10X, and the like are used to present a tactile sensation to the user. In other words, in the tactile sensation presentation apparatus 1X according to the comparative example, a plurality of members are used in order to present a tactile sensation to the user. However, if the number of components used in the tactile sensation presentation device 1X increases, the number of assembly steps of the tactile sensation presentation device 1X increases in the manufacturing steps of the tactile sensation presentation device 1X.

In contrast, in the tactile sensation presenting apparatus 1 according to the present embodiment, the tactile sensation can be presented to the user by incorporating the unit 4 as one component into an appropriate position without using the plurality of elastic portions 40X. In other words, in the present embodiment, the number of components into which the tactile sensation presentation apparatus 1 is incorporated can be reduced. Therefore, in the present embodiment, the assembly process of the tactile sensation presentation device 1 can be reduced in the manufacturing process of the tactile sensation presentation device 1.

in the comparative example, the elastic portion 40X is used as a coil spring so that the vibration target 2 can be displaced with respect to the housing 3. The coil spring can be deformed up, down, left and right. In the comparative example, in order to allow the coil spring to be deformed in the vertical direction, the process of connecting the elastic portion 40X between the vibration object 2 and the housing 3 may be complicated in the manufacturing process of the tactile sensation presenting device 1X. Further, after the tactile sensation presenting apparatus 1X is manufactured, the elastic portion 40X as a coil spring may be deformed in an unintended direction, and the vibration object 2 may vibrate in the unintended direction.

In contrast, in the present embodiment, in the manufacturing process of the tactile sensation presenting device 1, the elastic portion 40X is not directly incorporated into the tactile sensation presenting device 1, but the unit 4 including the elastic portions 40A and 40B is incorporated into the tactile sensation presenting device 1. Therefore, in the manufacturing process of the tactile sensation presentation device 1, the assembly process can be prevented from being complicated. In the module 4, a plate spring can be used as the elastic portions 40A and 40B. The direction in which the plate spring deforms is more restricted than, for example, a coil spring. Therefore, in the tactile sensation presentation device 1 according to the present embodiment, the vibration object 2 can be prevented from vibrating in an unintended direction.

In the comparative example, the positional relationship between the elastic portion 40X and the actuator 10X is appropriately adjusted according to the size of the vibration target 2. Therefore, if the size of the vibration object 2 is changed by a change in the product specification of the tactile sensation presentation apparatus 1X or the like, the positional relationship between the elastic portion 40X and the actuator 10X needs to be adjusted again.

In contrast, in the present embodiment, the positional relationship between the elastic portions 40A and 40B and the actuator 10 can be appropriately adjusted in the unit 4. Therefore, even if the size of the vibration target 2 is changed, the positional relationship between the elastic portions 40A and 40B and the actuator 10 does not need to be adjusted again. In the present embodiment, when the size of the vibration target 2 has been changed, the number of the components 4 incorporated in the tactile sensation presentation apparatus 1 may be adjusted. Therefore, the module 4 according to the present embodiment can have a structure excellent in convenience.

in the comparative example, when the tactile sensation presentation device 1X is an in-vehicle device, the traveling direction of the vehicle on which the tactile sensation presentation device 1X is mounted can be almost the X-axis direction. Therefore, if the vehicle on which the tactile sensation presentation device 1X is mounted suddenly starts or stops, acceleration in the X-axis direction acts. Here, in the comparative example, the actuator 10X and the housing 3 contact at two points on the base portion 14X, but contact the vibration target 2 at only one point on the holding portion 15X. Therefore, when acceleration in the X-axis direction acts, a force received from two points of the base portion 14X of the housing 3 acts on one point of the holding portion 15X, and the vibrating object 2 may be damaged. In this case, the actuator 10X may be damaged.

In contrast, in the present embodiment, when the tactile sensation presentation device 1 is an in-vehicle device, the first fixing portion 20 is fixed to the housing 3, and the second fixing portion 30 is fixed to the vibration object 2. Here, as shown in fig. 3 and 4, the first fixing portion 20 and the second fixing portion 30 have a larger area than the holding portion 15X and the like shown in fig. 5. Therefore, when the vehicle mounted with the tactile sensation presentation device 1 is suddenly started or stopped, the possibility of damage to the vibrating object 2 as in the comparative example can be reduced. In the present embodiment, in the tactile sensation presenting device 1, the elastic portions 40A and 40B are deformable in the Z-axis direction. Therefore, even if the vehicle is suddenly started or stopped and acceleration in the X axis direction is applied, a situation in which force is applied to the actuator 10 via the elastic portions 40A and 40B can be prevented. With the above configuration, the possibility of breakage of the actuator 10 can be reduced.

Further, in the comparative example, the actuator 10X is incorporated into the tactile sensation presentation apparatus 1X such that the support portion 13X is orthogonal to the bottom surface of the housing 3. With the above-described configuration, in the comparative example, the thickness of the tactile sensation presentation device 1X may increase.

In contrast, in the present embodiment, as shown in fig. 2 described above, the unit 4 is incorporated into the tactile sensation presentation device 1 such that the support portions 13 are parallel to the bottom surface of the housing 3. With the above configuration, in the present embodiment, the possibility of an increase in the thickness of the tactile sensation presentation device 1 can be reduced.

[ other structural examples of Components ]

Fig. 6 is a front view of the assembly 104 according to other embodiments of the present disclosure. Fig. 7 is a perspective view of the assembly 104 shown in fig. 6. The element 104 may be selected when the vibration direction of the vibration target 2 shown in fig. 1 is set to an in-plane direction, in other words, when the vibration target 2 shown in fig. 1 is intended to be vibrated laterally.

As shown in fig. 6, the unit 104 includes the actuator 10, the first fixing portion 120, the second fixing portion 30, and the elastic portion 140.

The first fixing portion 120 can be fixed to the base of the tactile sensation presentation device 1 shown in fig. 1, for example, the bottom surface of the housing 3 shown in fig. 2, as in the first fixing portion 20. The first fixing portion 120 may be formed of the same material as the first fixing portion 20. As shown in fig. 6, the first fixing portion 120 has leg portions 122A, 122B. The first fixing portion 120 may further have through holes 123A, 123B.

The foot 122A is fixed to one end of the base 50. The base portion 14A of the actuator 10 is interposed between the foot portion 122A and the base portion 50. The foot 122B is fixed to one end of the base 50. The base portion 14B of the actuator 10 is interposed between the foot portion 122B and the base portion 50.

The legs 122A and 122B may be fixed to the base 50 by a coupling member such as a screw or an adhesive, for example. For example, when the first fixing portion 120 does not have the through holes 123A and 123B, the leg portions 122A and 122B may be fixed to the bottom surface of the housing 3 shown in fig. 2 by an adhesive or the like.

The through hole 123A is provided in the leg 122A. The through hole 123B is provided in the leg 122B. As shown in fig. 2, the connecting member 5 such as a screw can be inserted into the through holes 123A and 123B. The first fixing portion 120 can be fixed to the bottom surface of the housing 3 by inserting the coupling member 5 into the through holes 123A and 123B.

the elastic part 140 may be a plate spring. The elastic part 140 connects the first fixing part 120 and the second fixing part 30. For example, one end of the elastic part 140 is connected to the leg part 122A of the first fixing part 120. The other end of the elastic portion 140 is connected to the leg portion 122B of the first fixing portion 120. The central portion of the elastic portion 140 is connected to the main body portion 31 of the second fixing portion 30.

Thus, the unit 104 includes one elastic portion 140, unlike the unit 4 including two elastic portions 40A and 40B shown in fig. 3 and 4. Even such a module 104 can provide the same effects as those of the module 4 described above.

[ Another example of the Structure of the Assembly ]

Fig. 8 is a front view of an assembly 204 according to another embodiment of the present disclosure. Fig. 9 is a perspective view of the assembly 204 shown in fig. 8. When the vibration direction of the vibration target 2 shown in fig. 1 is set to the out-of-plane direction, the block 204 can be selected. In other words, the component 204 may be selected when the vibrating object 2 shown in fig. 1 is intended to vibrate vertically.

As shown in fig. 8, the unit 204 includes the actuator 10, a first fixing portion 220, a second fixing portion 230, and elastic portions 40A and 40B.

The first fixing portion 220 can be fixed to the base of the tactile sensation presentation device 1 shown in fig. 1, for example, the bottom surface of the housing 3 shown in fig. 2, as in the first fixing portion 20. The first fixing portion 220 may be made of the same material as the first fixing portion 20. As shown in fig. 8, the first fixing portion 220 has leg portions 222A and 222B. The first fixing portion 220 may further have through holes 223A, 223B.

The leg 222A is fixed to one end of the base 50. The base portion 14A of the actuator 10 is interposed between the foot portion 222A and the base portion 50. The leg 222B is fixed to the other end of the base 50. The base 14B of the actuator 10 is interposed between the foot 222B and the base 50. The leg portions 222A and 222B may be fixed to the base portion 50 by a coupling member such as a screw or an adhesive, for example.

When the unit 204 is incorporated into the tactile sensation presentation apparatus 1 shown in fig. 2, the legs 222 and 222B are arranged perpendicular to the bottom surface of the housing 3 shown in fig. 2. At this time, the legs 222A and 222B are arranged perpendicularly to the bottom surface of the housing 3 so that the base 50 side becomes the housing 3 side.

As shown in fig. 9, the through-hole 223A is formed on the upper surface of the leg portion 222A. The through hole 223A penetrates from the upper surface of the leg 222A to the bottom surface of the base 50. As shown in fig. 9, the through-hole 223B is formed in the upper surface of the leg portion 222B. The through hole 223B penetrates from the upper surface of the leg 222B to the bottom surface of the base 50. By inserting a coupling member such as a screw into the through holes 223A and 223B, the first fixing portion 220 can be fixed to the bottom surface of the housing 3 shown in fig. 2 via the base portion 50.

The second fixing portion 230 can be fixed to the vibrating object 2 shown in fig. 2, as in the second fixing portion 30 described above. The second fixing portion 230 may be made of the same material as the second fixing portion 30. As shown in fig. 8, the second fixing portion 230 has a main body portion 231, a joint portion 232, and a joint surface 233.

The body 231 transmits the vibration of the vibrating plate 12 to the vibrating object 2 shown in fig. 2 via the joint surface 233 shown in fig. 9.

The joining portion 232 is joined to the vicinity of the center of the main surface 12b of the vibrating plate 12. By joining the joining portion 232 to the main surface 12b, the vibration of the vibrating plate 12 is transmitted to the main body portion 231 and to the vibrating object 2 shown in fig. 2.

As shown in fig. 9, the joint surface 233 may be the upper surface of the body 31. The bonding surface 233 is bonded to the vibrating object 2 shown in fig. 2 described above by an adhesive or the like, for example. The joint surface 233 is joined to the vibration target 2, and thereby the vibration of the vibration plate 12 is transmitted to the vibration target 2 as the vibration in the X-axis direction shown in fig. 2. In other words, the block 204 longitudinally vibrates the vibrating object 2 shown in fig. 1 described above in accordance with the expansion and contraction displacement of the piezoelectric element 11.

The module 204 as described above can achieve the same effects as those of the module 4 as described above.
