Some actuators that vibrate a movable body using a magnetic drive mechanism have a structure in which a terminal block is provided on a support to hold a terminal member for supplying power to a coil. In Japanese Patent Application No. 2019-156899, the applicant of the present application provides a terminal block protruding outward in the radial direction on a first support member overlapping from one side in the axial direction on a movable body, and two terminals held by the terminal block. The configuration is adopted in which the ends of the coil wires are entwined with each other.

When the end of the coil wire is entwined with the terminal held by the support, it is necessary to give the coil wire an appropriate degree of bending in order to prevent the coil wire from breaking. For example, at the time of assembling the actuator, a method is adopted in which the coil wire is entwined with the terminal member attached to the terminal block and then the terminal member is bent to give the coil wire flexibility. However, there is a problem that the terminal member comes off from the terminal block when a force is applied to bend the terminal member attached to the terminal block. If a jig having a special shape is used, bending can be performed so that the jig does not come off the terminal block, but such a jig is expensive.

Further, in an actuator that vibrates a movable body, when the terminal member is bent, the strength of the bent portion is lowered due to metal fatigue, so that the terminal member may be broken by the vibration.

In view of the above problems, an object of the present invention is to give bending to the coil wire without bending the terminal member at the time of assembly.

In order to solve the above problems, the actuator according to the present invention includes a support, a movable body, a connecting body connected to the support and the movable body, and having at least one of elasticity and viscoelasticity, a magnet, and a magnet. The support includes a coil, a magnetic drive mechanism that moves the movable body relative to the support, and the support includes a terminal member and a terminal block that holds the terminal member, and the terminal. The members include a terminal body protruding from the terminal block to one side in the first direction, a coil wire connecting portion to which a coil wire drawn from the coil is connected, and a shaft portion protruding in a direction intersecting the terminal body. , The terminal block intersects the first direction and intersects the second direction with the terminal insertion portion into which the terminal body is inserted on one side of the second direction intersecting the first direction. The terminal member includes a groove portion extending in a third direction, and the terminal member has the terminal body extending from a second position extending to one side in the second direction with the shaft portion arranged in the groove portion as a fulcrum. Is held by the terminal block in a state of being rotated to the first position extending to one side of the first direction.

According to the present invention, when the terminal member provided with the coil wire connecting portion is held by the terminal block provided on the support, the terminal member includes a shaft portion protruding in a direction intersecting the terminal body, and the terminal block is a shaft. It has a groove where the part can be placed. Therefore, since the terminal member can be rotated with the shaft portion as a fulcrum, the coil wire can be bent by rotating the terminal member after connecting the coil wire to the coil wire connecting portion. Therefore, it is possible to give the coil wire a bend without bending the terminal member at the time of assembly. This makes it possible to reduce the risk of the terminal member breaking due to metal fatigue due to bending. Further, it is possible to reduce the possibility that the terminal member will come off from the support during bending. Further, since it is not necessary to use an expensive jig for easy bending, the manufacturing cost of the actuator can be suppressed.

In the present invention, the terminal block includes a locking portion that restricts the movement of the terminal member in the first direction and the third direction, and the terminal member is locked to the locking portion. It is preferable to provide a portion. By doing so, it is possible to suppress the positional deviation of the terminal member.

It is possible to adopt a mode in which the arm portion fits into the locking groove by rotating to. In this way, the locked state can be formed by the operation of rotating the terminal member.

Alternatively, in the present invention, one of the locked portion and the locked portion is a locking hole, the other of the locked portion and the locked portion is a convex portion, and the terminal member is the terminal member. By rotating from the second position to the first position, the convex portion can be fitted into the locking hole. Even in this case, the locked state can be formed by the operation of rotating the terminal member.

In the present invention, the terminal block includes a stepped portion, and the terminal member includes a bent portion that fits into the stepped portion by rotating the terminal member from the second position to the first position. can do. In this way, the terminal member can be positioned by fitting the bent portion and the step portion. Therefore, the misalignment of the terminal member can be suppressed. Further, when the terminal member is inserted into the terminal insertion portion, the bent portion can be fitted to the edge of the terminal insertion portion. As a result, the terminal member can be held in the second position. Therefore, it is easy to solder the coil wire to the coil wire connection portion at the second position. Further, by adjusting the height of the step portion in the second direction, the position of the terminal member in the first position in the second direction can be appropriately set. For example, the terminal member can be positioned so that the terminal block and the terminal member are located on the same surface.

In the present invention, the groove portion includes a first groove portion arranged on one side of the terminal insertion portion in the third direction and a second groove portion arranged on the other side of the terminal insertion portion in the third direction. The shaft portion preferably includes a first shaft portion arranged in the first groove portion and a second shaft portion arranged in the second groove portion. By forming the groove portions on both sides of the terminal insertion portion in this way, the shaft portion can be inserted into the groove portion by inserting the terminal member inserted into the terminal insertion portion as it is. Therefore, the step of attaching the terminal member to the second position can be easily performed.

In the present invention, the terminal member includes a connection portion for connecting the coil wire connection portion and the terminal body, and the terminal block is the connection portion and the connection portion when the terminal member is rotated to the first position. It is preferable to provide a positioning portion that abuts in the second direction. In this way, the terminal member can be easily positioned at the first position.

It has a groove where the part can be placed. Therefore, since the terminal member can be rotated with the shaft portion as a fulcrum, the coil wire can be bent by rotating the terminal member after connecting the coil wire to the coil wire connecting portion. Therefore, it is possible to give the coil wire a bend without bending the terminal member at the time of assembly. This makes it possible to reduce the risk of the terminal member breaking due to metal fatigue due to bending. Further, it is possible to reduce the possibility that the terminal member will come off from the support during bending. Further, since it is not necessary to use an expensive jig for easy bending, the manufacturing cost of the actuator can be suppressed.

A lid portion 47 that covers from the other side Z2 in the Z-axis direction is provided. The end of the coil wire 69 (see FIG. 8A) drawn from the coil 60 is soldered to the terminal member 28. Therefore, by electrically connecting a wiring member such as a flexible wiring board or a lead wire to the terminal member 28, power can be supplied to the coil 60 via the terminal member 28. The detailed configuration of the terminal portion 7 will be described later.

(Movable body)
As shown in FIGS. 5 and 6, in the movable body 5, the magnet 50 is a disk-shaped permanent magnet arranged on the inner peripheral side of the coil 60 provided on the support 2. The magnet 50 is magnetized in the L direction of the axis, and the S pole and the N pole are arranged in the L direction of the axis.

There is. Therefore, at the center of the movable body 5, a through hole 55 that penetrates the movable body 5 in the axis L direction is provided by the holes 515, 505, and 525, respectively.

(Connector)
The connecting body 8 is a cylindrical viscoelastic member 80 provided between the outer peripheral surface 56 of the movable body 5 and the second wall portion 43 of the second support member 4. The viscoelastic member 80 extends so as to surround the movable body 5 over the entire circumference between the outer peripheral surface 56 of the movable body 5 and the second wall portion 43 of the second support member 4. In this embodiment, the center of gravity of the movable body 5 and the center of the viscoelastic member 80 in the Z-axis direction coincide with each other in the Z-axis direction. Therefore, there is an advantage that the movable body 5 is difficult to tilt.

Viscoelasticity is a property that combines both viscosity and elasticity, and is a property that is prominently found in polymer substances such as plastics and rubber. Therefore, various gel members can be used as the viscoelastic member 80. Further, as the viscoelastic member 80, natural rubber, diene rubber (for example, styrene / butadiene rubber, isoprene rubber, butadiene rubber), chloroprene rubber, acrylonitrile / butadiene rubber, etc.), non-diene rubber (for example, butyl rubber, ethylene, etc.) Various rubber materials such as propylene rubber, ethylene / propylene / diene rubber, urethane rubber, silicone rubber, fluororubber, etc., and thermoplastic elastomers, and modified materials thereof may be used.

In this embodiment, a gel-like member (gel-like damper member) such as a silicone gel is used as the viscoelastic member 80. For example, a silicone-based gel having a needle insertion degree of 80 to 110 degrees is used. The degree of needle insertion is defined by JIS-K-2207 and JIS-K-2220, and the smaller this value is, the harder it is.

The viscoelastic member 80 is joined to the tubular body portion 522 of the second yoke 52 and the second wall portion 43 of the second support member 4 by the adhesiveness of the viscoelastic member 80 itself. That is, in this embodiment, a material for forming a silicone gel is filled between the outer peripheral surface 56 of the movable body 5 and the second wall portion 43 of the support 2, and then cured to form the viscoelastic member 80. .. As a result, the viscoelastic member 80 is joined to the outer peripheral surface 56 (cylindrical body portion 522) of the movable body 5 and the second wall portion 43 of the support 2 due to the adhesiveness of the viscoelastic member 80 itself. By applying a primer to the outer peripheral surface 56 and the second wall portion 43 before filling the material for forming the silicone gel, the viscoelastic member 80 with respect to the outer peripheral surface 56 and the second wall portion 43 can be obtained. The bonding strength can be increased.

The viscoelastic member 80 (gel-like member) configured in this way has linear or non-linear stretching characteristics depending on the stretching direction thereof. For example, when a plate-shaped gel-like member is pressed in the thickness direction and compressed and deformed, the non-linear component has a larger expansion and contraction characteristic than the linear component, while the plate-shaped gel-like member is pulled and stretched in the thickness direction. , Has a stretch characteristic in which the linear component is larger than the non-linear component. Further, even when the deformation is performed in the direction intersecting the thickness direction (shearing direction), the linear component has a larger deformation characteristic than the non-linear component. In this embodiment, the viscoelastic member 80 is configured to be deformed in the shear direction when the movable body 5 vibrates in the Z-axis direction. Therefore, since the viscoelastic member 80 is deformed in a range of high linearity, it is possible to obtain vibration characteristics with good linearity.

(Actuator heat dissipation structure)
In the support 2, the second support member 4 is provided with a window 41 that opens the flat plate portion 521 of the second yoke 52 of the movable body 5 toward the other side L2 in the axis L direction. Therefore, when the movable body 5 is vibrated in the axis L direction, air enters and exits from the inside of the support 2 through the window 41. Further, the movable body 5 is provided with a through hole 55. Therefore, when the movable body 5 is vibrated in the axis L direction, air enters and exits through the through hole 55 and the window 41. Therefore, the temperature rise of the coil 60 can be suppressed.

Further, in the support body 2, an opening 325 is provided in the end plate portion 31 of the first support member 3. Therefore, when the movable body 5 is vibrated in the axis L direction, air enters and exits from the inside of the support 2 through the opening 325. Therefore, since the coil 60 can be cooled, the temperature rise of the coil 60 can be suppressed.

(Basic operation of actuator)
In the actuator 1 of this embodiment, when an alternating current is applied to the coil 60, the movable body 5 vibrates in the Z-axis direction, so that the center of gravity of the actuator 1 fluctuates in the Z-axis direction. Therefore, the user who holds the actuator 1 as a tactile device can experience the vibration in the Z-axis direction. At that time, by adjusting the AC waveform applied to the coil 60, the acceleration at which the movable body 5 moves to one side Z1 in the Z-axis direction and the acceleration at which the movable body 5 moves to the other side Z2 in the Z-axis direction are different. Then, the user can experience the vibration having directionality in the Z-axis direction.

Further, the actuator 1 can form a panel speaker by fixing the end plate portion 31 of the support 2 in the Z-axis direction to the back surface of the diaphragm via an adhesive layer or the like. In this case, when a signal having a predetermined waveform is applied to the coil 60, the movable body 5 vibrates in the Z-axis direction, and the reaction force is transmitted to the diaphragm. Therefore, as a result of the diaphragm vibrating, a sound corresponding to the alternating current applied to the coil 60 is generated from the front surface of the diaphragm.
