A vibrator-mounted holder is attached to a casing of a vibration generator which moves a vibrator to generate a vibration when used. The vibrator-mounted holder includes a vibrator, a vibrator retention unit retaining the vibrator, a fixing unit fixed to a casing, and an arm. The vibrator includes a magnet having a plate shape parallel to a horizontal surface and a yoke arranged on the magnet. The arm connects the fixing unit to the vibrator retention unit, and supports the vibrator retention unit in a manner that the vibrator retention unit is displaceable with respect to the fixing unit. The yoke has a projecting portion which is projected downward and fixed to the vibrator retention unit. The arm is connected to a portion, at which the projecting portion is arranged, within the vibrator retention units.

Vibration generator moving vibrator by magnetic field generated by coil and vibrator-mounted holder used in vibration-generator

In accordance with one aspect of the present disclosure, a vibration generating device includes a protruding part; a base provided with the protruding part and formed of a magnetic body; an annular coil surrounding the protruding part; a plate facing the base and formed of a magnetic body; and an elastic member supporting the plate with respect to the base. The plate and the base constitute magnetic circuit.

Vibration generating device and electronic device

In accordance with one aspect of the present disclosure, an electronic device includes a housing, a contact member attached to the housing, a plate displaceable with respect to the base, an elastic member supporting the plate with respect to the base. The base, the plate and the elastic member are arranged inside the housing. A magnetic gap is formed with the plate and the base. The plate connects with the contact member.

Electronic device

A motor includes a frame having an outer diameter of 10 millimeters or less and an inner surface. The motor also includes an annular magnet attached to the inner surface of the frame, a bracket provided at the frame, and a columnar brush formed of carbon and having an outer peripheral surface. In addition, the motor includes a commutator contacting the outer peripheral surface of the brush, and an elastic member supporting the brush at the bracket. A part of the elastic member is disposed inside of the columnar brush.

Motor having columnar brush

In accordance with one aspect of the present disclosure, an electronic device includes a housing, a contact member attached to the housing, and a vibration generating device. The vibration generating device is fixed to the contact member or the housing. A gap is formed between a surface of the vibration generating device facing the housing and a surface of the housing facing the vibration generating device.

A motor including: a frame having an outer diameter of 10 millimeters or less and an inner surface; an annular magnet attached to the inner surface of the frame; a bracket provided at the frame; a columnar brush formed of carbon and having an outer peripheral surface; a commutator contacting the outer peripheral surface of the brush; and an elastic member supporting the brush at the bracket, in which a part of the elastic member is inside the brush.
