Abstract
A vibration motor and an electronic device are provided. The vibration motor may be applied to electronic devices such as a mobile phone and a PAD. A partial region of a first side wall of a housing of the vibration motor protrudes outward to form a concave cavity with an opening facing a movable component. A driving coil is partially or completely located in the concave cavity. In a case that a same electromagnetic force is achieved, the vibration motor in this application may reduce a height of the driving coil protruding from the opening of the concave cavity as much as possible.
Claims21
A vibration motor, comprising a housing, wherein a driving coil and a movable component are disposed in an inner cavity of the housing, and the driving coil is configured to drive the movable component to reciprocate relative to the housing to generate vibration:
- a first side wall of the housing has a protruding portion protruding toward a side facing away from the movable component, the protruding portion forms a concave cavity with an opening facing the movable component, and the driving coil is at least partially located in the concave cavity.
An electronic device, comprising a vibration motor, wherein the vibration motor is fixed to the electronic device through a bracket, and along a direction in which the protruding portion protrudes, an outer wall of the protruding portion does not exceed an outer wall of the bracket, wherein the vibration motor, comprising a housing, wherein a driving coil and a movable component are disposed in an inner cavity of the housing, and the driving coil is configured to drive the movable component to reciprocate relative to the housing to generate vibration:
- a first side wall of the housing has a protruding portion protruding toward a side facing away from the movable component, the protruding portion forms a concave cavity with an opening facing the movable component, and the driving coil is at least partially located in the concave cavity.
