Claims

[Scope of utility model registration request]

(1) A magnetic field forming mechanism having an annular gap capable of forming a DC magnetic field, an electrically conductive movable member fitted into the gap, and connected to an annular portion of the movable member located outward from the gap. and a fixed coil capable of forming an alternating magnetic field in the gap in order to generate an induced alternating current in the conductive movable member and vibrate the vibrating member. An inductive vibration generator, characterized in that a slit-shaped insulating layer is provided in the annular portion of the movable member in order to prevent electric current from flowing through the annular portion of the movable member.

(2) The induction type vibration generator according to claim 1, wherein the conductive movable member is configured as a cylindrical body made of a conductor.

(3) The slit-shaped insulating layer is configured as a slit cut in the upper surface of the annular portion in a direction intersecting the circumferential direction.
The induction type vibration generator described in 2.

(4) The induced vibration generator according to any one of claims 1 to 3, wherein a plurality of the slit insulating layers are provided at intervals over the entire circumference of the annular portion. .
