Actuator

Abstract

The invention provides an actuator which can prevent a coil wire connected with a power supply substrate from being broken so as to improve falling impact resistance. In an actuator (1), a power supply substrate (10) to which coil wires (56, 57) are connected is held on a coil holder (4) covered by a housing (3), and thus, an impact during falling is not likely to spread to the power supply substrate (10) via the housing (3). Furthermore, even when an impact spreads during falling, the power supply substrate (10) moves together with the coil holder (4), and the situation in which the coil wires (56, 57) are stretched does not occur easily. Therefore, the situation that the coil wires (56, 57) are broken due to the impact during falling does not easily occur, so that the falling impact resistance can be improved. In addition, in the coil holder (4), the power supply substrate (10) is provided at a position separated from a contact portion in contact with a movable body (6). Therefore, even if the movable body (6) contacts with the contact part of the coil holder (4), the impact is not liable to spread to the power supply substrate (10).

Description

technical field [0001] The present invention relates to an actuator that vibrates a movable body. Background technique [0002] As a device for notifying information by vibration, an actuator is proposed, which includes: a movable body with a permanent magnet, a support body with a coil facing the permanent magnet, and a coil holder for holding the coil on the support body. frame, a case covering the movable body and the coil holder, and a power supply substrate to which coil wires constituting the coil are connected (see Patent Document 1). In the actuator described in Patent Document 1, the power supply substrate is fixed to the case so as to protrude from the case. [0003] When the actuator described in Patent Document 1 is incorporated in a device such as a remote controller or a game controller, the device may drop, so high drop impact resistance is required. However, in the actuator described in Patent Document 1, since the power supply board is fixed to the case, t...

AI Technical Summary

Problems solved by technology

However, in the actuator described in Patent Document 1, since the power supply board is fixed to the case, the impact when dropped is transmitted to the power supply board through the case.

At this time, if the power supply board moves in a direction away from the coil, the coil wire is stretched and the coil wire is likely to be disconnected near the place where the coil wire is soldered to the power supply board.
