Claims
- 1. An apparatus comprising:a vibration motor having: a base having a front surface; a rotary member provided on the front surface of the base; and a cover having an electromagnetically shielding property and a top and sides covering the rotary member, wherein the top has a flat surface; a board on which the vibration motor is mounted; and a shield member covering at least a part of the board, wherein the vibration motor is disposed inside the shield member.
- 2. An apparatus according to claim 1, wherein the cover has a hole for connecting spaces of inside and outside of the cover to each other.
- 3. An apparatus according to claim 1, wherein the cover perfectly contacts to the front surface of the base to perform positioning of the cover in a height direction.
- 4. An apparatus according to claim 1, further comprising a fillet formed on an outside of the base and used for positioning the vibration motor.
- 5. An apparatus according to claim 1, wherein the cover is electrically connected to the board.
- 6. Portable electronic equipment comprising an apparatus according to claim 1.
- 7. An apparatus according to claim 1, wherein the cover is made of resin;the cover is coated with non-electrolytic copper; and the cover coated with non-electrolytic copper is coated with non-electrolytic nickel.
- 8. An apparatus according to claim 7, wherein the resin is selected from the group consisting of acrylonitrile, butadiene and styrene.
- 9. An apparatus comprising:a vibration motor having: a base having a front surface; a rotary member provided on the front surface on the base; an eccentric member provided on the rotary member; and a cover having an electromagnetically shielding property and covering the rotary member and the eccentric member; a board on which the vibration motor base is mounted, and a shield member covering at least a part of the board, wherein the vibration motor is disposed inside the shield member.
- 10. An apparatus according to claim 9, wherein the cover has a hole for connecting spaces of inside and outside of the cover to each other.
- 11. An apparatus according to claim 9, wherein the cover contacts to the front surface of the base to perform positioning of the cover in a height direction.
- 12. An apparatus according to claim 9, further comprising a fillet formed on an outside of the base and used for positioning the vibration motor.
