Horizontal vibration motor

摘要

Disclosed is a horizontal vibration motor, the motor including a stator having a coil block secured to a bottom plate of a case, a vibrator having magnets placed above the coil block and a weight holding the magnets, a first elastic member having a first elastic plate secured to portion of the case corresponding to a first corner of the weight, a second elastic plate bent inwards from the first elastic plate, and a third elastic plate bent outwards from the second elastic plate and secured to portion around a second corner, and a second elastic member having a fourth elastic plate secured to portion of the bottom plate corresponding to a third corner, a fifth elastic plate bent inwards from the fourth elastic plate, and a sixth elastic plate bent outwards from the fifth elastic plate and secured to a fourth corner.

主权项

1. A horizontal vibration motor, comprising:
a stator including a coil block disposed on a bottom plate of a case; a vibrator including magnets and a weight holding the magnets, the weight having a shape of a rectangular frame, and the magnets being placed over the coil block; a first elastic member including a first elastic plate secured to a portion of the case corresponding to a first corner of the weight, a second elastic plate bent in a first direction from the first elastic plate, and a third elastic plate bent in a second direction opposite to the first direction from the second elastic plate and secured to a portion around a second corner that is adjacent to the first corner; and a second elastic member including a fourth elastic plate secured to a portion of the bottom plate corresponding to a third corner that is located in a diagonal direction of the first corner, a fifth elastic plate bent in the first direction from the fourth elastic plate, and a sixth elastic plate bent in the second direction from the fifth elastic plate and secured to a fourth corner that is located in a diagonal direction of the second corner; wherein a gap between the first and second elastic plates is wider than a gap, between the second and third elastic plates, and a gap between the fourth and fifth elastic plates is wider than a gap between the fifth and sixth elastic plates.
