Further, on the other side Y2 (the center side) of the holder side plate portion 35 in the third direction Y, a power feeding substrate support groove 342 is provided on the inner side surface of the holder side plate portion 34.

(Structure of Power supply substrate)

As shown in fig. 7 and 8, the power feeding board 50 has a flat board main body 51 having a concave shape as a whole, and has a first land 52 and a second land 53 on a surface of one side Y1 in the third direction Y.

The first pads 52 and the second pads 53 are provided on the surface of the substrate body 51 on the one side Y1 in the third direction Y, and are spaced apart in the second direction X. The

coil pads

521 and 531 are disposed between the

The first inclined portion 332b is inclined toward the center in the third direction Y as approaching the boundary portion 332c with the first opening portion 332a from one side in the first direction Z. In addition, it is preferable that the inclination angle θ of the first inclined portion 332b is reduced at the boundary portion 332d between the first inclined portion 332b and the surface of the holder-side plate portion 35 so as not to provide a step. Alternatively, the boundary portion 332d may be rounded so as not to be bent. The thickness T1 of the first inclined portion 332b at the boundary portion 332c is preferably as small as possible. For example, the height of the boundary portion 332c is set to be equal to the height of the external wire pad 522.

In addition, in the boundary 333d between the second inclined portion 333b and the surface of the holder-side plate portion 35, the inclination angle of the second inclined portion 333b and the thickness of the second inclined portion 333b at the boundary 333c may be considered to be the same as the inclination angle θ of the first inclined portion 332b and the thickness T1 of the first inclined portion 332b at the boundary 332c, so that no step is provided.

(Structure of magnetic drive Circuit 40)

Fig. 6 is a perspective view of the magnetic drive circuit 40. As shown in fig. 2, 5 and 6, the magnetic drive circuit 40 has an air-core coil 31 wound in an oblong shape, and a coil wire 311 of the coil 31 is connected to the power supply substrate 50 of the coil holder 30 (see fig. 8).

(action)

When power is supplied to the coil 31 from the outside (higher-order apparatus) via the power supply substrate 50, the movable body 12 is reciprocated in the second direction X along the plate portion 39 of the coil holder 30 inside the support body 11 by the magnetic drive circuit 40, and the magnetic drive circuit 40 includes the coil 31, the first permanent magnet 411, and the second permanent magnet 412. Thereby, the user holding the actuator 10A can obtain information by the vibration from the actuator 10A.

(action and Effect)

In the actuator 10A, the movable body 12 and the support 11 are in contact with the damper 13 at positions facing each other, and the damper 13 has elasticity or viscoelasticity. Therefore, the occurrence of resonance in the movable body 12 can be suppressed. A magnetic drive circuit 40 is provided, the magnetic drive circuit 40 including a coil 31 and a permanent magnet 41, the permanent magnet 41 being provided so as to face the coil 31, and vibrating the movable body 12 in the second direction X with respect to the support 11. The support 11 is provided with a power feeding board 50 electrically connected to the coil 31, and power is supplied from the outside by connecting wires to a first land 52 and a second land 53, the magnetic driving circuit 40 is operated and the movable body 12 is vibrated, and the first land 52 and the second land 53 are provided on the power feeding board 50.

The holder side plate portion 35 of the support body 11 is provided with an opening portion 33A that is open in the third direction Y, and the power supply substrate 50 is exposed to the outside of the support body 11 through the opening portion 33A. The holder-side plate portion 35 is provided with a first recess 332A and a second recess 333A, the first recess 332A extending toward the first pad 52 and reaching the edge of the opening 33A, the second recess 333A extending toward the second pad 53 and reaching the edge of the opening 33A, and the first recess 332A and the second recess 333A are provided with a first inclined portion 332b and a second inclined portion 333b, and the first inclined portion 332b and the second inclined portion 333b are inclined so as to become deeper toward the opening 33A. Therefore, the level difference of the edge of the opening 33A can be reduced, and the level difference of the end portions of the first inclined portion 332b and the second inclined portion 333b opposite to the opening 33A can be eliminated. Thus, the electric wire 14 connected to the first pad 52 and the second pad 53 is routed from the opening 33A to the outside of the support 11 through the first inclined portion 332b and the second inclined portion 333b of the first concave portion 332A and the second concave portion 333A, and therefore, disconnection due to a step can be prevented.

In the actuator 10A, the holder-side plate portion 35 includes a first recess 332A and a second recess 333A, and the first recess 332A and the second recess 333A are provided adjacent to each other in the arrangement direction of the first pad 52 and the second pad 53 and spaced apart from each other in the arrangement direction. Therefore, the wire 14 bonded to the first pad 52 can be wired through the first concave portion 332A, and the wire 14 bonded to the second pad 53 can be wired through the second concave portion 333A, so that the wiring work can be easily performed.

Fig. 9 is an overall perspective view of the actuator 10B as viewed from above from one side Y1 in the third direction Y, and the actuator 10B is another example of the actuator for explaining the embodiment of the present invention. Fig. 10 is a perspective view of the coil holder 30 from which the power supply substrate 50 has been removed. Fig. 11 is a perspective view of the actuator 10B cut in the first recess 332B.

As shown in fig. 9 to 11, in the actuator 10B, the width W2 of the first recess 332B in the opening 33B is narrower than the width W1 of the external electric wire land 522 in the first land 52, and the width W2 of the second recess 333B is narrower than the width W1 of the external electric wire land 532 in the second land 53. The first concave portion 332B and the second concave portion 333B have a common structure, and therefore the second concave portion 333B will be described below.

As shown in fig. 11, the second recess 333B includes a first inclined surface 333e connected to the opening main body 331, and has a recess main body 333f and a second inclined surface 333g continuously extending toward the one side X1 in the second direction X. The first inclined surface 333e has a truncated cone shape, and the diameter thereof is enlarged toward the opening main body 331. The concave body 333f is a groove having a substantially semicircular or U-shaped cross section and extending in the second direction X. The inner diameter of the recess body 333f is slightly smaller than the outer diameter of the electric wire 14. The second inclined surface 333g is a bottom surface of the recess main body 333f, and is inclined toward the side Y1 in the third direction Y to the side Z1 in the first direction Z.

In the actuator 10B, the width W2 of the first recess 332B and the second recess 333B is narrower than the width W1 of the external-wire land 522 and the external-wire land 532. Therefore, when the wire 14 is soldered to the external wire land 522 and the external wire land 532, the wire 14 does not rattle inside the first concave portion 332B and the second concave portion 333B, and workability is improved.

In the actuator 10B, since the first recess 332B and the second recess 333B have a U-shaped cross section, the electric wire 14 connected to the first pad 52 and the second pad 53 can be reliably held, and workability is improved.

Fig. 12 is an overall perspective view of the actuator 10C as viewed from above on the side Y1 in the third direction Y, and the actuator 10C is another example of the actuator for explaining the embodiment of the present invention.

In the actuator 10C, the opening 33C is integrally formed by continuously providing the first recess 332C and the second recess 333C in the arrangement direction of the first pad 52 and the second pad 53. That is, the first inclined portion 332b is continuously and integrally formed with the second inclined portion 333 b. Therefore, the shape of the opening 33C in the coil holder 30 is simplified, and the manufacturing becomes easy.

Fig. 13 is a front view of the actuator 10D as viewed from a side Y1 in the third direction Y, and the actuator 10D is another example of the actuator for explaining the embodiment of the present invention.

In the actuator 10D, the first recess 332D and the second recess 333D are provided on opposite sides of the first pad 52 and the second pad 53. Therefore, the wire 14 bonded to the first land 52 can be wired to one side X1 in the second direction X through the first concave portion 332D, and the wire 14 bonded to the second land 53 can be wired to the other side X2 in the second direction X through the second concave portion 333D.
