actuator

Abstract

The present invention provides an actuator capable of preventing disconnection of a coil wire connected to a power supply substrate, thereby improving drop impact resistance. In the actuator (1), the power supply substrate (10) to which the coil wires (56, 57) are connected is held on the coil holder (4) covered by the case (3), so that the impact when falling is not easy It propagates to the power supply substrate (10) via the housing (3). In addition, even in the case of the shock propagation when falling, since the power supply substrate (10) moves together with the coil holder (4), the situation that the coil wires (56, 57) are stretched is less likely to occur. Therefore, since the coil wires (56, 57) are less likely to be disconnected due to the impact of the drop, the drop impact resistance performance can be improved. In addition, in the coil holder (4), the power supply substrate (10) is provided at a position separated from the contact portion with the movable body (6). Therefore, even if the movable body (6) comes into contact with the contact portion of the coil holder (4), the impact at this time does not easily propagate to the power supply board (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.
