Actuator
An actuator may include a movable body, a support body, a connection body having at least one of elasticity and viscoelasticity, and a magnetic drive circuit having a coil provided in one side member of the movable body and the support body, and a permanent magnet provided in the other side member to vibrate the movable body. The one side member may include a coil holder and a power feeding circuit board fixed to the coil holder in a state that one side face of the circuit board faces an outer side, and the one side face may have a land connected with a coil wire structuring the coil. The circuit board may be fixed to the coil holder in a state that the one side face is retracted from an end face of the coil holder, and the coil wire may have a slack portion fixed to the one side face.
1. An actuator comprising:
a movable body;
a support body;
a connection body which is provided with at least one of elasticity and viscoelasticity and is disposed so as to contact with both of the movable body and the support body at a position where the movable body and the support body are faced each other; and
a magnetic drive circuit which comprises:
a coil provided in the support body; and
a permanent magnet provided in the movable body so as to face the coil in a first direction;
wherein the magnetic drive circuit is structured to vibrate the movable body with respect to the support body in a second direction intersecting the first direction;
wherein the support body comprises:
a coil holder which holds the coil; and
a power feeding circuit board which is fixed to the coil holder in a state that one side face of the power feeding circuit board faces an outer side, the one side face being provided with a land connected with a coil wire structuring the coil with a solder;
wherein the coil holder comprises a plate part which is extended in a third direction intersecting the first direction and the second direction, and the coil is disposed in the plate part;
wherein the plate part comprises a side plate part formed toward the first direction at an end part on one side in the third direction of the plate part, and the side plate part structures an end face of the coil holder in the third direction;
wherein the side plate part comprises a step part which is retracted from the end face of the coil holder and an opening part in which the power feeding circuit board is fixed to the coil holder in a state that the one side face is retracted from the end face of the coil holder;
wherein the side plate part of the coil holder comprises a guide groove which is opened in the step part for guiding the coil wire from the coil to the power feeding circuit board;
wherein the coil wire comprises a slack portion provided between the coil and a connected position with the power feeding circuit board, and the slack portion is fixed to the one side face with an adhesive; and
wherein the slack portion of the coil wire is fixed to the step part and the one side face of the power feeding circuit board with an adhesive at a position retracted from the end face of the coil holder.
2. The actuator according to claim 1 , wherein the step part and the one side face are located on a same imaginary plane.
3. The actuator according to claim 2 , wherein the solder and the adhesive are located at positions retracted from the end face of the coil holder.
4. The actuator according to claim 1 , wherein the solder and the adhesive are located at positions retracted from the end face of the coil holder.
