DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Each embodiment and each modified example of the present invention will be described in detail below with reference to the drawings. In addition, in all drawings referred to for describing each embodiment and each modified example, the same reference numerals are used for identical or substantially identical configurations and elements. In addition, as a rule, configurations and elements that have been described once will not be described repeatedly. In the following description, unless otherwise specified, terms such as "first" and "second" are used only to distinguish components from each other, and do not represent a specific order or sequence.

[0010] [Each configuration of the first embodiment] FIG. 1 shows a part of a home electric appliance 10 equipped with a vibration device 20 according to the first embodiment.

[0011] [Home appliances] The home appliance 10 has a housing 12 and a vibration device 20 provided in the housing 12. Examples of the home appliance 10 include an electric fan, a washing machine, a television, a recorder, and a lighting device. Here, the direction in which a movable part 32 of the vibration device 20, which will be described later, vibrates is the up-down direction. The up-down direction is an example of a first direction. Directions perpendicular to the up-down direction are the front-rear direction and the left-right direction. The front-rear direction and the left-right direction are examples of a second direction intersecting with the first direction. The home appliance 10 is provided with a display panel (not shown). An instruction message for an operator M (FIG. 4) and the like are displayed on the display panel. The instruction message includes content instructing the operator M to touch a predetermined part of the home appliance 10. In this embodiment, the predetermined part means a part of the home appliance 10 where the vibration device 20 is provided.

[0012] <Case> The housing 12 has an upper wall 13 located on the upper side in the up-down direction, and a bottom wall 14 located on the lower side of the upper wall 13. An upper surface 13A of the upper wall 13 is a flat surface that extends in the front-rear and left-right directions.

[0013] <Vibration device> The vibration device 20 is provided at a portion of the housing 12 that is touched by a finger F (FIG. 4) of an operator M. Specifically, the vibration device 20 is fixed to the inside of the housing 12. In addition, an upper portion of the vibration device 20 is exposed upward (outside) from the upper wall 13.

[0014] 2, the vibration device 20 is configured as a disk-shaped unit having a predetermined thickness in the vertical direction. That is, the vibration device 20 has a central axis C. The central axis C extends along the vertical direction. An FPC (flexible printed circuit board) 48, which will be described later, protrudes from a part of the outer periphery of the vibration device 20. Specifically, the vibration device 20 has a case part 22, a movable part 32, a driving part 38, and an elastic member 54.

[0015] <Case section> The case part 22 is an example of a housing part that houses the movable part 32. The case part 22 is supported by the housing 12 (FIG. 1) by being fixed to the bottom wall 14 (FIG. 1). The case part 22 has, as an example, a case main body 24 made of resin and end plates 28 made of metal.

[0016] <<Case body>> The case body 24 has a cylindrical portion 25 formed in an annular shape centered on the central axis C, and an upper plate portion 26 covering the upper end portion of the cylindrical portion 25. The lower end portion of the case body 24 is open in the vertical direction. A notch portion 25A is formed in a part of the lower end portion and in the circumferential direction of the cylindrical portion 25. The notch portion 25A opens radially outward from the central axis C.

[0017] The upper plate portion 26 is formed in a disk shape having a predetermined thickness in the vertical direction. The upper plate portion 26 is provided with an opening 27 that penetrates the upper plate portion 26 in the vertical direction. In other words, the case portion 22 is provided with an opening 27 that opens in the vertical direction. The opening 27 is a circular hole portion (a portion including a through hole and an edge portion of the through hole) having a center on the central axis C. The radius of the opening 27 is R1 (mm).

[0018] As shown in Fig. 3, the upper surface 26A of the upper plate portion 26 and the upper surface 27A of the opening 27 are aligned at the same height. On the other hand, the lower surface 27B of the opening 27 protrudes downward from the lower surface 26B of the upper plate portion 26 in the vertical direction. A step portion 29 is formed at the lower portion of the cylindrical portion 25. The step portion 29 has a mounting surface 29A extending in the radial direction of the cylindrical portion 25 and a vertical surface 29B extending downward from the outer end of the mounting surface 29A in the radial direction. In other words, the step portion 29 is a portion where the lower end portion of the cylindrical portion 25 is cut out so as to have an L-shaped cross section.

[0019] <<End plate>> 2, end plate 28 is a disk-shaped member having a predetermined thickness in the vertical direction. End plate 28 constitutes the bottom of case portion 22. Specifically, end plate 28 is adhered to the lower end of cylindrical portion 25 to close the space inside case main body 24. End plate 28 is welded or adhered to the lower end of cylindrical portion 25 with movable portion 32, elastic member 54, and drive portion 38 housed inside case main body 24. End plate 28 has an upper surface 28A.

[0020] <Movable part> The movable part 32 is located at a position in the vibration device 20 where a finger F (FIG. 4) of an operator M touches. The movable part 32 is an example of a predetermined part that the operator M touches. The movable part 32 is made of a metal member. The movable part 32 has a cylindrical part 33 formed in an annular shape centered on a central axis C, a top plate part 34 covering an upper end part of the cylindrical part 33, and a flange part 35 extending radially outward from a lower end part of the cylindrical part 33. The lower end part of the movable part 32 is open downward.

[0021] The top plate portion 34 is formed in a disk shape having a predetermined thickness in the vertical direction. The top plate portion 34 is the part of the movable portion 32 that is touched by a finger F (FIG. 4). The top plate portion 34 has an upper surface 34A and a lower surface 34B. The radius of the top plate portion 34 and the radius of the cylindrical portion 33 are equal. The radius of the top plate portion 34 is R2 (mm). The radius R2 is smaller than the radius R1.

[0022] The flange portion 35 is formed in an annular shape when viewed from the top-bottom direction. The flange portion 35 has a lower surface 35A. The radius from the central axis C to the outermost peripheral position of the flange portion 35 is R3 (mm). The radius R3 is larger than the radius R1. In other words, the flange portion 35 cannot pass through the opening 27. On the other hand, the cylindrical portion 33 and the top plate portion 34 can pass through the opening 27 in the top-bottom direction. In this way, the movable portion 32 is housed in the case portion 22 such that the upper portion can protrude from the opening 27 to the outside (upper side) of the case portion 22. In other words, the movable portion 32 faces the outside of the case portion 22 through the opening 27. The reciprocating motion of the movable portion 32 can be transmitted to the operator M as vibration. In addition, "a state in which movable part 32 faces the outside of case part 22 through opening 27" includes a state in which upper surface 34A of movable part 32 is positioned above upper surface 26A, a state in which upper surface 34A and upper surface 26A are positioned at the same height, and a state in which upper surface 34A is positioned below upper surface 26A.

[0023] <Drive unit> The driving section 38 has a control unit 30 (FIG. 1), a magnet 42, a pole piece 44, a coil 46, and an FPC 48. The supply of electricity to the coil 46 in the driving section 38 is controlled by the control unit 30. As an example, the control unit 30 controls the supply of electricity to the coil 46 so that the movable section 32 reciprocates in the up-down direction and the upper end of the movable section 32 protrudes outward (upward) beyond the case section 22.

[0024] <<Magnet>> The magnet 42 is formed in a cylindrical shape having a predetermined height in the vertical direction, centered on the central axis C. The vertical height of the magnet 42 is lower than the vertical height of the cylindrical portion 25. The upper surface 42A and the lower surface 42B of the magnet 42 are formed in a flat shape. The upper surface 42A and the lower surface 42B are aligned along the horizontal direction including the front-rear direction and the left-right direction. The maximum radius of the magnet 42 is R4 (mm). The radius R4 is smaller than the radius R2. Thus, the magnet 42 has a size that can be accommodated inside the movable portion 32.

[0025] The upper surface 42A is bonded to the center of the lower surface 34B (FIG. 3) of the top plate portion 34. This allows the magnet 42 to move vertically integrally with the movable portion 32. The magnetic poles of the magnet 42 are arranged such that the upper side is the N pole and the lower side is the S pole.

[0026] <<Pole piece>> The pole piece 44 is made of a magnetic material. The pole piece 44 is formed in a disk shape having a predetermined thickness in the vertical direction. The radius of the pole piece 44 is approximately equal to the radius R4 of the magnet 42. The top surface 44A of the pole piece 44 in the vertical direction is bonded to the bottom surface 42B of the magnet 42. This allows the magnet 42 and the pole piece 44 to move vertically together with the movable part 32. Both the magnet 42 and the pole piece 44 are housed within the cylindrical part 25.

[0027] <<Coil>> The coil 46 is wound in a cylindrical shape centered on the central axis C. The coil 46 is connected to a power source, and generates a magnetic field when a current is supplied from the power source. A hollow portion 47 is formed radially inside the coil 46. The radius of the hollow portion 47 is R5 (mm). The size of the radius R5 is larger than the radius R4 and smaller than the radius R2.

[0028] In a non-energized state where no current is supplied to the coil 46, the lower part of the magnet 42 and the pole piece 44 are located (stationary) inside the hollow part 47. In a powered state where a current is supplied to the coil 46, the magnet 42 and the pole piece 44 move vertically relative to the coil 46 due to the action of a magnetic force (magnetic field) generated in the coil 46. Specifically, the direction of current flow to the coil 46 alternates, causing the magnet 42 and the pole piece 44 to reciprocate vertically. In other words, the movable part 32 vibrates vertically.

[0029] < <fpc>> The FPC 48 is provided with a wiring pattern (not shown). The FPC 48 has a disk portion 49 and an extension portion 51. The disk portion 49 supports the coil 46. A portion of the wiring pattern of the disk portion 49 is connected to the coil 46. The disk portion 49 is fixed to the upper surface 28A of the end plate 28.

[0030] The extension portion 51 is a portion extending in a band shape radially outward from the disk portion 49. The tip of the extension portion 51 passes through the notch portion 25A and protrudes to the outside of the case portion 22. A wiring portion (not shown) of the extension portion 51 is connected to the control unit 30 (FIG. 1) and a power source.

[0031] <<Control unit>> 1, the control unit 30 is connected to the FPC 48. The control unit 30 controls the supply of electricity to the coil 46 (FIG. 2) to control the vibration of the movable part 32. The control unit 30 also functions as a power supply unit from a power source to the vibration device 20, for example. The drive unit 38 (FIG. 2) may be controlled by an external control unit different from the control unit 30.

[0032] <Elastic material> The elastic member 54 shown in FIG. 2 is an example of an elastic portion, and is made of a metal member. The elastic member 54 is provided in the case portion 22 so as to be elastically deformable. The elastic member 54 supports the movable portion 32. Specifically, the elastic member 54 is a flat plate-like member having a predetermined thickness in the vertical direction in a stationary state where it is not elastically deformed. The outer shape of the elastic member 54 is circular. The center of the elastic member 54 is located on the central axis C. The radius of the elastic member 54 is larger than the radius R3 of the movable portion 32 and smaller than the radius of the case portion 22.

[0033] The elastic member 54 has an outer fixing portion 55, an inner fixing portion 56, and a connecting portion 57. The outer fixing portion 55 is an annular portion and constitutes the outer edge of the elastic member 54. The inner fixing portion 56 is an annular portion and is located more inward than the outer fixing portion 55 and the connecting portion 57. The inner fixing portion 56 is located so as to overlap with the flange portion 35 in the up-down direction. The lower surface of the flange portion 35 is fixed to the upper surface of the inner fixing portion 56 by welding, for example.

[0034] The connection portion 57 connects the outer fixing portion 55 and the inner fixing portion 56. The connection portion 57 is elastically deformable in the up-down direction. The connection portion 57 has, as an example, three connection plate portions 58. The three connection plate portions 58 are provided at positions shifted by 120° in the circumferential direction of the elastic member 54. The three connection plate portions 58 extend in an arc shape along the circumferential direction of the elastic member 54. The connection portion 57 may have one or two connection plate portions 58, or may have four or more connection plate portions 58.

[0035] 4, the outer fixing part 55 is attached to the case part 22 by being adhered to the mounting surface 29A from below. When the vibration device 20 is in a completed state, a space is formed between the outer fixing part 55 and the FPC 48. This allows the connection part 57 to be elastically deformable in the vertical direction.

[0036] 3 indicates the upper end position of the range in which the upper surface 34A of the movable part 32 can move. Position P2 indicated by the imaginary line indicates the lower end position of the range in which the lower surface 35A of the movable part 32 can move. In other words, the movable part 32 can vibrate in the vertical direction within a range S from position P1 to position P2.

[0037] [Operation of the first embodiment] The operation of the vibration device 20 according to the first embodiment will be described.

[0038] 1 and 4, the control unit 30 displays an instruction message for the operator M on a display panel (not shown). For example, the instruction message is "Please touch the vibration device 20 with your finger F." Then, the control unit 30 energizes the coil 46 from the power source. This causes the movable part 32 to start vibrating (reciprocating) in the up-down direction.

[0039] Following the instruction message, the operator M touches the upper surface 34A, or the upper surface 34A and the upper surface 26A with his / her finger F. Here, the upper end of the movable part 32 vibrates so as to protrude above the upper surface 26A. As a result, the operator M directly receives the vibration of the movable part 32 with his / her finger F. In other words, the reciprocating motion of the movable part 32 is transmitted to the operator M as vibration, so that the operator M can easily feel the sensation of touching the vibration device 20. At this time, the elastic member 54 elastically deforms, so that the transmission of vibration from the movable part 32 to the case part 22 is suppressed, and therefore the transmission of vibration from the case part 22 to the housing 12 is suppressed.

[0040] As described above, in the vibration device 20, the elastic member 54 supporting the movable part 32 is elastically deformed, thereby suppressing the transmission of vibration from the movable part 32 to the case part 22. This suppresses the transmission of vibration to other parts (housing 12) different from the vibration device 20 touched by the operator M. Furthermore, the movable part 32 reciprocates while protruding outward from the opening 27 of the case part 22. As a result, the operator M receives the vibration of the movable part 32 directly with his / her finger F, which makes it easier for the operator M to feel the sensation of touching the vibration device 20.

[0041] In addition, by having the upper portion of the movable part 32 protrude to the outside of the case part 22, it becomes possible to transmit the vibration of the movable part 32 more strongly to the finger F of the operator M. Then, when the movable part 32 protrudes from the case part 22, the position of the movable part 32 becomes easier for the operator M to understand, so that the operator M can easily know where to touch the vibration device 20.

[0042] [Configurations of the second embodiment] 5 shows a vibration device 60 according to the second embodiment. The vibration device 60 is provided in the home appliance 10 in place of the vibration device 20 (FIG. 1). Note that configurations and elements that are the same or substantially the same as those of the vibration device 20 are denoted by the same reference numerals and descriptions thereof will be omitted.

[0043] 6, the vibration device 60 has a case portion 62, a movable portion 76, a driving portion 38, and an elastic member 54. The vibration device 60 has a central axis C.

[0044] <Case section> The case part 62 is an example of a housing part that houses the movable part 76. The case part 62 is supported and fixed to the bottom wall 14 (FIG. 5). The case part 62 has, as an example, a resin case main body 64 and an end plate 28.

[0045] <<Case body>> 7 has a cylindrical portion 65 formed in an annular shape centered on a central axis C, and an upper plate portion 66 covering an upper end portion of the cylindrical portion 65. The lower end portion of the case body 64 is open in the vertical direction. A notch portion 25A is formed in a part of the lower end portion of the cylindrical portion 65 in the circumferential direction.

[0046] The upper plate portion 66 is formed in a disk shape having a predetermined thickness in the vertical direction. The upper plate portion 66 is provided with an opening portion 67 that penetrates the upper plate portion 66 in the vertical direction. In other words, the case portion 62 is provided with an opening portion 67 that opens in the vertical direction. Furthermore, the case portion 62 is provided with a wall portion 68.

[0047] <<<Wall>>> The wall portion 68 is formed in a plate shape having a predetermined thickness in the up-down direction. The wall portion 68 has an upper surface 69. The length equivalent to the thickness of the wall portion 68 in the up-down direction is defined as L1 (mm). The wall portion 68 extends radially inward from three edges of the opening portion 67 and is connected to each other. In other words, the wall portion 68 is located radially inward from the opening portion 67. The wall portion 68 divides the opening portion 67 into a plurality of holes. Specifically, the wall portion 68 has one first partition wall 68A and three second partition walls 68B.

[0048] The first partition 68A is formed in an annular shape with its center located on the central axis C. The three second partitions 68B are located at equal intervals in the circumferential direction of the first partition 68A. The three second partitions 68B extend radially outward from the first partition 68A and connect the first partition 68A to three edges of the opening 67. The wall 68 is also an example of a limiting portion that limits the outward (upward) movement of the movable portion 76, which will be described later, in the up-down direction. In other words, the wall 68 is located inside the opening 67 in the front-rear and left-right directions and limits the outward movement of the movable portion 76 in the up-down direction.

[0049] The width W1 (mm) of the first partition 68A in the radial direction of the upper plate portion 66 and the width W2 (mm) of the second partition 68B in the circumferential direction of the upper plate portion 66 are approximately the same size. As described above, the first partition 68A and the second partition 68B are connected to each other. This increases the rigidity of the wall portion 68 against external forces acting from the outside to the inside in the vertical direction of the case portion 62 and external forces acting from the inside to the outside. In other words, the wall portion 68 is configured to be able to resist external forces acting in the vertical direction.

[0050] The first partition 68A and the second partition 68B divide the opening 67 into one hole 72 and three hole portions 74. The hole portion 72 is a circular through-hole whose center is located on the central axis C. The hole portion 74 is located radially outward from the hole portion 72. The hole portion 74 is an arc-shaped through-hole.

[0051] 8, a step portion 29 is formed at the lower end of the cylindrical portion 65. The outer fixing portion 55 of the elastic member 54 is adhered to the mounting surface 29A.

[0052] <Movable part> The movable part 76 shown in FIG. 7 is located at a position on the vibration device 20 where the finger F (FIG. 8) of the operator M touches. The movable part 76 is an example of a predetermined part that the operator M touches. The movable part 76 is made of a metal member. The movable part 76 differs in configuration from the movable part 32 (FIG. 2) in that a groove part 78 is provided in the top plate part 34. In other words, the movable part 76 and the movable part 32 have the same configuration except for the groove part 78. For this reason, the same reference numerals as the movable part 32 are used for the same configuration as the movable part 32, and the description thereof will be omitted.

[0053] <<Groove>> The groove portion 78 is a portion recessed downward from the upper surface 34A. The cross-sectional shape of the groove portion 78 is a U-shape that opens upward. The groove portion 78 has one first groove 78A and three second grooves 78B. The first groove 78A is formed in an annular shape with its center located on the central axis C. The three second grooves 78B are positioned at equal intervals in the circumferential direction. In addition, the three second grooves 78B extend linearly from the first groove 78A to the outside in the radial direction and penetrate to the outer periphery of the top plate portion 34. The bottom surface 79 of the groove portion 78 is formed in a flat shape along the horizontal direction.

[0054] The top plate portion 34 is divided into one circular portion 81 and three arc portions 82 by the groove portion 78. The upper surface of the circular portion 81 and the upper surfaces of the arc portions 82 form the upper surface 34A. That is, the one circular portion 81 and the three arc portions 82 have the same height of the upper surface. Here, the wall portion 68 is inserted into the groove portion 78. Specifically, the first partition 68A is inserted into the first groove 78A. The second partition 68B is inserted into the second groove 78B.

[0055] The circular portion 81 is inserted into the hole 72. The three arc portions 82 are inserted into the three holes 74. The length equivalent to the vertical depth of the groove 78 is L2 (mm). The length L2 is longer than the length L1. In other words, the groove 78 allows the movable portion 76 to move relative to the wall portion 68 in the vertical direction.

[0056] When the lower surface of the wall portion 68 is in contact with the bottom surface 79, the upper surface 34A of the one circular portion 81 and the upper surfaces 34A of the three arcuate portions 82 protrude upward from the wall portion 68. On the other hand, when the vertical height of the upper surface 34A and the vertical height of the upper surface 69 are aligned, a space is formed between the wall portion 68 and the bottom surface 79. Note that in the vibration device 60, before the movable portion 76 starts to vibrate, the vertical height of the upper surface 34A and the vertical height of the upper surface 69 are aligned.

[0057] [Operation of the second embodiment] The operation of the vibration device 60 according to the second embodiment will be described.

[0058] In the home appliance 10 shown in FIG. 8, an instruction message is displayed to encourage the operator to touch the vibration device 60, and the movable part 76 starts vibrating in the vertical direction. The operator M touches the upper surface 34A, or the upper surface 34A and the upper surface 26A, with his / her finger F in accordance with the instruction message. Here, the upper end of the movable part 76 vibrates so as to protrude above the upper surface 26A. As a result, the operator M receives the vibration of the movable part 76 directly with his / her finger F, and thus it becomes easier for the operator M to feel the sensation of touching the vibration device 60. At this time, the elastic member 54 is elastically deformed, so that the transmission of vibration from the movable part 76 to the case part 22 is suppressed, and therefore the transmission of vibration from the case part 22 to the housing 12 is suppressed.

[0059] By having the upper part of the movable part 76 protrude to the outside of the case part 22, it becomes possible to transmit the vibration of the movable part 76 more strongly to the finger F of the operator M. Then, when the movable part 76 protrudes from the case part 22, the position of the movable part 76 becomes easier for the operator M to understand, so that the operator M can easily know where to touch the vibration device 60.

[0060] In the vibration device 60, the finger F of the operator M may come into contact with the wall portion 68. Here, the wall portion 68 resists an external force acting from the outside to the inside of the case portion 22 (external force received from the finger F), so that the movable portion 76 can be prevented from being pushed downward more than necessary.

[0061] In the vibration device 60, the wall portion 68 is provided so as to divide the opening 67 into one hole portion 72 and three hole portions 74 (FIG. 7). This makes it easier for the finger F to come into contact with the wall portion 68 compared to a configuration in which the wall portion 68 protrudes only at a portion of the edge of the opening 67. This further prevents the movable portion 76 from being pushed downward more than necessary.

[0062] In the vibration device 60, the wall portion 68 is inserted into the groove portion 78, but the movable portion 76 is allowed to move in the vertical direction. That is, in the vertical direction, a space (gap) is formed between the bottom surface 79 of the groove portion 78 and the wall portion 68. As a result, even if the wall portion 68 covers a part of the opening 67, the vertical movement of the movable portion 76 is unlikely to be restricted by the wall portion 68, so that the vertical movement range of the movable portion 76 can be secured within a necessary range.

[0063] In the vibration device 60, when the movable part 76 moves in the up-down direction to the outside (upper side) of the case part 62, the wall part 68 functions as a limiting part, thereby limiting the movable part 76 from moving more than necessary. As a result, even if the vibration state of the movable part 76 fluctuates and the movable part 76 moves more upward than necessary, the movement is limited, so that the movable part 76 can be prevented from moving more than necessary to the outside of the case part 62.

[0064] [Modification of the second embodiment] 9 shows a part of a vibration device 90 which is a modified example of the vibration device 60 (FIG. 7) of the second embodiment. The same components as those of the vibration device 60 are denoted by the same reference numerals and will not be described. The vibration device 90 differs in that the wall 68 (FIG. 7) of the vibration device 60 is replaced with a wall 92, and the groove 78 (FIG. 7) is replaced with a groove 94.

[0065] The wall portion 92 has one first partition 68A and two second partitions 68B. The two second partitions 68B are aligned in a straight line in the radial direction. The groove portion 94 has one first groove 78A and two second grooves 78B. The two second grooves 78B are aligned in a straight line in the radial direction. In this manner, a configuration may be used in which the wall portion 92 divides the opening 67 into two in the circumferential direction, and the groove portion 94 divides the top plate portion 34 into two in the circumferential direction.

[0066] [Configurations of the third embodiment] 10 shows a vibration device 100 according to a third embodiment. The vibration device 100 is provided in the home appliance 10 in place of the vibration device 20 (FIG. 1). Note that configurations and elements that are the same or substantially the same as those of the vibration device 20 are denoted by the same reference numerals and will not be described.

[0067] 11, the vibration device 100 includes a case 102, a movable part 32, a driving part 132, and an elastic member 142. The vibration device 100 has a central axis C.

[0068] <Case section> The case part 102 is an example of a housing part that houses the movable part 32. The case part 102 is supported by the bottom wall 14 (FIG. 10). The case part 102 has, as an example, an inner case 104 made of resin and an outer case 116 made of resin. The outer case 116 is fixed to the bottom wall 14.

[0069] <<Inner case>> 12, the inner case 104 has a cylindrical portion 106, an upper plate portion 108, three pillar portions 112, and two protrusions 114. The lower end portion of the inner case 104 is open in the vertical direction.

[0070] The cylindrical portion 106 is formed in an annular shape centered on a central axis C. The surface located at the lower end of the cylindrical portion 106 is defined as a lower surface 106A. The cylindrical portion 106 also has an outer circumferential surface 106B. The height of the cylindrical portion 106 in the vertical direction is defined as h1 (mm).

[0071] Upper plate portion 108 is formed integrally with cylindrical portion 106, and covers the upper end portion of cylindrical portion 106. Upper plate portion 108 is formed in a disk shape having a predetermined thickness in the vertical direction. Upper plate portion 108 is provided with an opening 27 that penetrates upper plate portion 108 in the vertical direction. In other words, case portion 102 is provided with an opening 27 that opens in the vertical direction. The surface of the upper end of upper plate portion 108 is referred to as upper surface 108A (FIG. 11).

[0072] The three pillar portions 112 are disposed at equal intervals (central angle 120°) in the circumferential direction of the upper plate portion 108, and each has the same configuration. For this reason, one pillar portion 112 will be described. The pillar portion 112 is curved along the circumferential direction of the cylindrical portion 106. The pillar portion 112 extends downward from the lower surface of the upper plate portion 108 along the up-down direction. The outer peripheral surface of the pillar portion 112 is integrated with the inner peripheral surface of the cylindrical portion 106. The lower end portion of the pillar portion 112 protrudes downward from the lower surface 106A. The surface located at the lower end of the pillar portion 112 is referred to as the lower surface 112A.

[0073] The two protrusions 114 protrude radially outward from the outer circumferential surface 106B. The two protrusions 114 have the same configuration except for their arrangement. As an example, the protrusions 114 are formed in a rectangular parallelepiped shape with a vertical height of about h1 / 2 (mm). The center positions PA, PB of the two protrusions 114 in the circumferential direction of the cylindrical portion 106 are on an axis K perpendicular to the central axis C. As an example, one pillar portion 112 is located on the axis K.

[0074] <<Outer case>> 11, outer case 116 has a cylindrical portion 118, a bottom plate portion 122, two guide portions 124, and one insertion portion 126. Outer case 116 houses inner case 104 so that the inner case 104 is movable in the up and down directions.

[0075] The cylindrical portion 118 is formed in an annular shape centered on the central axis C. A step portion 119 is formed at the lower end of the inner circumferential surface of the cylindrical portion 118. An annular mounting surface 119A is formed at the upper end of the step portion 119. The vertical height of the cylindrical portion 118 is defined as h2 (mm). The height h2 is greater than the height h1 (FIG. 12).

[0076] Bottom plate portion 122 is formed in a disk shape having a predetermined thickness in the vertical direction. Bottom plate portion 122 is formed integrally with cylindrical portion 118, and covers the lower end portion of cylindrical portion 118. On the other hand, the upper end portion of outer case 116 is open in the vertical direction.

[0077] The two guide portions 124 are each formed from an inner wall portion of a through hole that radially penetrates the cylindrical portion 118. The two guide portions 124 are located on the axis K (FIG. 12). The guide portions 124 extend in the vertical direction and have a size that allows them to engage with the protrusions 114. As a result, the two guide portions 124 guide the two protrusions 114 within a predetermined range in the vertical direction.

[0078] The insertion portion 126 radially penetrates a part of the cylindrical portion 118. An extension portion 136 of an FPC 134, which will be described later, is inserted into the insertion portion 126.

[0079] <Drive unit> The driving unit 132 has a magnet 42, a pole piece 44, a coil 46, and an FPC 134. The operation of the driving unit 132 is controlled by the control unit 30 (FIG. 10). The driving unit 132 reciprocates the movable part 32 in the up-down direction so that the movable part 32 protrudes to the outside of the case part 102.

[0080] < <fpc>> The FPC 134 is provided with a wiring pattern (not shown). The FPC 134 has a disk portion 135 and an extending portion 136. The disk portion 135 supports the coil 46. A portion of the wiring pattern of the disk portion 135 is connected to the coil 46. The disk portion 135 is fixed to an inner fixing portion 148 of a second elastic member 146 described later.

[0081] The extending portion 136 is a band-shaped portion extending radially outward from the disk portion 135. A portion of the extending portion 136 is bent at two locations. A tip portion of the extending portion 136 passes through the insertion portion 126 and protrudes to the outside of the outer case 116. A wiring portion (not shown) of the extending portion 136 is connected to the control unit 30 and a power source (not shown).

[0082] <Elastic material> The elastic member 142 is an example of an elastic portion, and is made of a metal member. The elastic member 142 has a first elastic member 144 and a second elastic member 146. The first elastic member 144 and the second elastic member 146 are positioned with a gap between them in the up-down direction. Furthermore, the first elastic member 144 and the second elastic member 146 are positioned so as not to interfere with each other, regardless of the presence or absence of elastic deformation of each.

[0083] <<First elastic member>> As an example, the first elastic member 144 has the same configuration as the elastic member 54 (FIG. 2). Therefore, a description of the specific configuration of the first elastic member 144 will be omitted. The outer fixing part 55 of the first elastic member 144 is attached to the lower surface 106A from below. In other words, the first elastic member 144 is provided on the inner case 104 so as to be elastically deformable. Furthermore, the first elastic member 144 supports the movable part 32.

[0084] <<Second elastic member>> The second elastic member 146 is provided on the outer case 116 so as to be elastically deformable. Furthermore, the second elastic member 146 supports the inner case 104. Specifically, the second elastic member 146 is a flat plate-like member having a predetermined thickness in the vertical direction in a stationary state where it is not elastically deformed. The outer shape of the second elastic member 146 is circular. The center of the second elastic member 146 is located on the central axis C. The outer diameter of the second elastic member 146 is larger than the outer diameter of the first elastic member 144 and smaller than the outer diameter of the outer case 116.

[0085] 12, the second elastic member 146 has an outer fixing portion 147, an inner fixing portion 148, a connecting portion 149, and an attachment portion 152. The outer fixing portion 147 is an annular portion and constitutes the outer edge of the second elastic member 146. The inner fixing portion 148 is an annular portion and is located more inward than the outer fixing portion 147, the connecting portion 149, and the attachment portion 152.

[0086] The connection portion 149 connects the outer fixing portion 147 and the inner fixing portion 148. The connection portion 149 is elastically deformable in the up-down direction. The connection portion 149 has three connection plate portions 151, for example. The three connection plate portions 151 are positioned at equal intervals of 120° in the circumferential direction of the second elastic member 146. The three connection plate portions 151 extend in an arc shape along the circumferential direction of the second elastic member 146. In this embodiment, the connection portion 149 has three connection plate portions 151, but may have one or two connection plate portions 151, or may have four or more connection plate portions 151.

[0087] The mounting portion 152 has three mounting plate portions 153, for example. The upper end surface of the mounting plate portions 153 is defined as an upper surface 153A (FIG. 11). The three mounting plate portions 153 are positioned at equal intervals of 120° in the circumferential direction of the second elastic member 146. The three mounting plate portions 153 are positioned to face the three pillar portions 112 in the up-down direction. The three lower surfaces 112A are respectively adhered to the three upper surfaces 153A.

[0088] 11, the outer fixing portion 147 is attached to the outer case 116 by being adhered to the mounting surface 119A from above. Note that, in a state where the vibration device 100 is completed, a space portion 155 (FIG. 13) that allows elastic deformation of the second elastic member 146 in the vertical direction is provided between the bottom plate portion 122 and the second elastic member 146. In this manner, the second elastic member 146 is provided on the outer case 116 in an elastically deformable manner, and supports the inner case 104.

[0089] [Operation of the third embodiment] The operation of the vibration device 100 according to the third embodiment will be described.

[0090] In the home appliance 10 shown in FIG. 13, an instruction message is displayed to encourage the operator to touch the vibration device 100, and the movable part 32 starts vibrating in the up-down direction. The operator M touches the upper surface 108A, or the upper surface 108A and the upper surface 34A, with his / her finger F in accordance with the instruction message. Here, the upper end of the movable part 32 vibrates so as to protrude above the upper surface 108A. As a result, the operator M receives the vibration of the movable part 32 directly with his / her finger F, and thus, the operator M can easily feel the sensation of touching the vibration device 100. At this time, the elastic member 142 is elastically deformed, so that the transmission of vibration from the movable part 32 to the case part 102 is suppressed, and therefore the transmission of vibration from the case part 102 to the housing 12 is suppressed.

[0091] Furthermore, when the finger F presses the upper surface 108A downward (when the inner case 104 is pressed downward), the presence of the space 155 allows the second elastic member 146 to deform in the vertical direction (downward). Furthermore, the second elastic member 146 suppresses the transmission of vibration from the movable part 32 to the outer case 116 via the inner case 104. Also, the elastic deformation of the second elastic member 146 increases the amount by which the inner case 104 can be pressed in the vertical direction (downward).

[0092] In this way, in the vibration device 100, the transmission of vibration from the movable part 32 to the housing 12 can be suppressed by the elastic deformation of the elastic member 142. Furthermore, in addition to making it easier for the operator M to feel the sensation of touching the vibration device 100, the operator M can also easily feel the sensation of operation by pressing the movable part 32 and the inner case 104 downward.

[0093] In the vibration device 100, the upper part of the movable part 32 protrudes to the outside of the inner case 104, so that the vibration of the movable part 32 can be more strongly transmitted to the finger F of the operator M. When the movable part 32 protrudes from the inner case 104, the position of the movable part 32 becomes easy for the operator M to understand, so that the operator M can easily know where to touch the vibration device 100.

[0094] [Configurations of the fourth embodiment] 14 shows a part of a home appliance 160. The home appliance 160 has a main body 162 and an operation unit 164 provided on the main body 162. The home appliance 160 is an electric appliance for home use. Examples of the home appliance 160 include an electric fan, a washing machine, a television, a recorder, and lighting equipment. One example of the home appliance 160 is an electric fan. The home appliance 160 stands upright in the vertical direction. The main body 162 has a motor and a fan (not shown).

[0095] The operation unit 164 includes a housing 165, a display panel 166, a control unit 168, and three vibration devices 170 (170A, 170B, 170C). The housing 165 is formed in a box shape including a bottom wall 167 and an upper wall 169. The display panel 166 is provided on the upper wall 169. The display panel 166 is capable of displaying messages related to operation commands for the three vibration devices 170. The control unit 168 is provided inside the housing 165.

[0096] The control unit 168 includes a CPU (Central Processing Unit) and a memory. The control unit 168 operates the motor and the fan of the main body unit 162 based on the operation signals transmitted from the vibration devices 170A, 170B, and 170C. The control unit 168 also displays messages related to the operation of the vibration devices 170A, 170B, and 170C and information on the operating state of the main body unit 162 on the display panel 166.

[0097] The vibration devices 170A, 170B, and 170C each function as an operation button of the operation unit 164. The vibration devices 170A, 170B, and 170C each have the same structure, and only the operation items assigned thereto are different. For this reason, when describing a specific structure, they will be described as one vibration device 170. On the other hand, when distinguishing the vibration devices 170 according to their operations, they will be described as vibration devices 170A, 170B, and 170C.

[0098] The vibration devices 170A, 170B, and 170C are configured to vibrate when operated with a finger F (FIG. 17). The vibration device 170A is used to switch the operation time of the home appliance 160. The vibration device 170B is used to switch the mode (strong wind, normal wind, weak wind) of the home appliance 160. The vibration device 170C is used to switch the operation of the home appliance 160 between ON and OFF.

[0099] 15, an upper portion of the vibration device 170 protrudes upward from an upper wall 169 of the housing 165. In addition, in describing the configuration of the vibration device 170, configurations and elements that are the same or substantially the same as those of the vibration device 20 (FIG. 1) are denoted by the same reference numerals and description thereof is omitted. Specifically, the vibration device 170 has a configuration in which a sensor film 172 and a control chip 174 are added to the vibration device 20 (FIG. 1).

[0100] 16, the sensor film 172 is formed in a disk shape having a predetermined thickness in the vertical direction, and its center is located on the central axis C. The control chip 174 is electrically connected to the sensor film 172 via the FPC 48.

[0101] 17, the sensor film 172 covers the top surface 26A and the top surface 34A from above. As an example, the outer periphery of the sensor film 172 is adhered to the top surface 26A with an adhesive 176. As an example, the inner periphery of the sensor film 172 is positioned at a distance from the top surface 34A in the up-down direction (in an unadhered state). The sensor film 172 is an example of a detection unit that detects whether or not the movable part 32 is operated by the finger F of the operator M, and is a capacitance-type sensor.

[0102] The control chip 174 constitutes a part of the detection unit. The control chip 174 functions as a switch unit that transmits each detection signal, an ON signal and an OFF signal, from the sensor film 172 to the control unit 168 (FIG. 15). When the finger F touches the sensor film 172, the control chip 174 transmits an ON signal to the control unit 168 based on a change in capacitance in the sensor film 172. In addition, when the finger F is removed from the sensor film 172, the control chip 174 transmits an OFF signal to the control unit 168 based on a change in capacitance in the sensor film 172.

[0103] When the control unit 168 receives an ON signal, the drive unit 38 starts the reciprocating movement of the movable part 32. In other words, when the sensor film 172 detects an operation (ON, OFF) of the movable part 32 by the finger F, the drive unit 38 starts or stops the reciprocating movement of the movable part 32.

[0104] [Operation of the fourth embodiment] In the home appliance 160 shown in FIG. 17, when an operator M tries to operate the movable part 32 with a finger F, the finger F touches the sensor film 172, causing the control chip 174 to transmit an ON signal to the control unit 168 (FIG. 15). The control unit 168 then operates the drive unit 38 to vibrate the movable part 32 in the vertical direction. Here, the movable part 32 reciprocates (vibrates) in the vertical direction. This makes it easier for the operator M to feel the sensation of touching the vibration device 170 by receiving the vibration of the movable part 32 with the finger F via the sensor film 172. Furthermore, the operator M can also feel the operation of the movable part 32. Note that the elastic member 54 is elastically deformed, thereby suppressing the transmission of vibration from the case part 22 to the housing 165.

[0105] In the vibration device 170, when the movable part 32 is in a stationary state (stopped state), a space (gap) exists between the sensor film 172 and the movable part 32. Therefore, even if the raised movable part 32 and the sensor film 172 come into contact with each other when the movable part 32 vibrates, it is possible to prevent an excessive load from acting on the sensor film 172.

[0106] Moreover, in the vibration device 170, the sensor film 172 is provided on the case portion 22. Therefore, the distance between the sensor film 172 and the movable portion 32 is shorter than in a configuration in which the sensor film 172 is provided on another portion of the housing 165. As a result, when the operator M tries to operate the movable portion 32 with his / her finger F, the finger F is more likely to come into contact with the sensor film 172, and it becomes easier to detect that the movable portion 32 is being operated. In other words, it is possible to shorten the time difference between the time when the operator M operates the movable portion 32 and the time when the movable portion 32 starts vibrating, so that the operator M is less likely to feel uncomfortable when operating the movable portion 32.

[0107] In the vibration device 170, the upper part of the movable part 32 protrudes to the outside of the case part 22, so that the vibration of the movable part 32 can be more strongly transmitted to the finger F of the operator M. Then, when the movable part 32 protrudes from the case part 22, the position of the movable part 32 becomes easy for the operator M to understand, so that the operator M can easily know where to touch the vibration device 170.

[0108] [Modifications] Below, modifications different from the first, second, third and fourth embodiments will be described. Note that components that are the same as or similar to those in the first, second, third and fourth embodiments will be given the same reference numerals and descriptions thereof will be omitted.

[0109] <First Modification> 18 shows a vibration device 180 of a first modified example. The vibration device 180 has a configuration in which a piezoelectric film sensor 182 is added to the vibration device 20 (FIG. 1). The piezoelectric film sensor 182 is an example of a detection unit that detects whether or not the movable part 32 is operated. Specifically, in the vibration device 180, the piezoelectric film sensor 182 is provided between the vibration device 180 and the housing 12. The piezoelectric film sensor 182 detects the pressing force that the case part 22 receives from a finger F, and transmits a detection signal to the control unit 30 (FIG. 1).

[0110] For example, when the operator M operates the movable part 32, the finger F presses the movable part 32 downward with the finger F straddling the movable part 32 and the case part 22. At this time, the piezoelectric film sensor 182 detects the pressing, and the control unit 30 drives the drive part 38, so that the movable part 32 vibrates in the up-down direction. This allows the operator M to get a sense of operation from the vibration of the movable part 32.

[0111] <Second Modification> 19 shows a vibration device 190 of a second modified example. The vibration device 190 has a configuration in which sensor films 192, 194 are added to the vibration device 20 (FIG. 1). The sensor films 192, 194 are an example of a detection unit that detects whether or not the movable part 32 is operated, and are capacitance-type sensors. The sensor film 192 is adhered to the upper surface 34A of the movable part 32. The sensor film 194 is formed in a ring shape and adhered to the upper surface 26A.

[0112] The sensor film 192 directly detects whether or not the movable part 32 is being operated by the operator M. The sensor film 194 can indirectly detect whether or not the movable part 32 is being operated by detecting contact with a part of the finger F when the operator M is operating the movable part 32. Information on whether or not the movable part 32 is being operated, detected by the sensor films 192, 194, is transmitted to the control unit 30 (FIG. 1).

[0113] When the sensor film 192 detects that "operation has been performed," or when the sensor films 192 and 194 detect that "operation has been performed," the control unit 30 determines that the movable part 32 is being operated. Therefore, the movable part 32 is driven by the drive unit 38.

[0114] On the other hand, when "no operation" is detected by the sensor film 192, the movable part 32 is not driven. For example, when "no operation" is detected by the sensor film 192, the movable part 32 is not driven even if "operation is performed" is detected by the sensor film 194. This is because the finger F is touching only the case part 22, and not the movable part 32.

[0115] <Other Modifications> The present invention is not limited to the above-described embodiments and modifications, and it goes without saying that various modifications, such as combinations, are possible without departing from the spirit of the present invention.

[0116] The vibration device 90 may not have the first partition 68A. In other words, one second partition 68B may extend in the radial direction and define the opening 67. In addition, the one second partition 68B may be formed in a protrusion shape, so that the opening 67 does not have to be defined into a plurality of holes.

[0117] A protrusion protruding in the radial direction may be provided on the cylindrical portion 33 of the movable portion 32, and a limiting portion that comes into contact with the protrusion may be provided on the case portion 22. The limiting portion and the protrusion come into contact in the vertical direction, thereby limiting the upward movement of the movable portion 32 within a predetermined range. Furthermore, the protrusion and the limiting portion may each be made of a magnet, and the same magnetic poles may be opposed to each other to generate a repulsive force and limit the upward movement of the movable portion 32.

[0118] In each embodiment and each modified example, the movable part 32 is not limited to one in which the upper surface 34A can protrude outward (upward) from the upper surface 26A, but may be one in which the upper surface 34A is positioned at the same height in the up-down direction as the upper surface 26A (not protruding). Furthermore, the movable part 32 may be one in which the upper surface 34A is positioned inward (lower) than the upper surface 26A as long as the finger F can contact the upper surface 34A. In any case, an indirect operation state may be used in which a member such as a film is interposed between the finger F and the upper surface 34A.
