Vibration generator moving vibrator by magnetic field generated by coil and vibrator-mounted holder used in vibration-generator
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.
1. A vibration generator comprising:
a plate-like coil;
a frame;
a weight;
a bent plate; and
an elastic material,
wherein the weight is supported by the elastic material with respect to the frame and the weight can be displaced laterally with respect to the face of the coil,
wherein a part of the elastic material is arranged between a side portion of the weight and a part of the bent plate,
wherein the side portion of the weight bulges toward the part of the elastic material, and
wherein the bent plate is attached to the side portion of the weight.
2. The vibration generator according to claim 1 , wherein
the elastic material includes an arm and a retention unit, and
the retention unit is arranged between the side portion of the weight and the part of the bent plate.
3. The vibration generator according to claim 1 , wherein
the bent plate includes a face facing the weight and a side edge portion bending from the face toward the retention unit, and
the part of the bent plate is the side edge portion.
4. The vibration generator according to claim 1 , wherein the elastic material is formed with resin.
