Abstract
A horizontal linear vibration motor for securing the straightness of a coil spring and preventing a driving unit, such as a mass body, from axially rotating around the axis of a shaft within a housing due to the rotational property of the coil spring by providing a coil and a magnet for generating a force that enables the reciprocating motion of the driving unit including the mass body and an anti-rotation member provided in the driving unit to slide and come into contact with the housing.
Claims8
A horizontal linear vibration motor comprising:
- a housing (2) configured to have an internal space;
- a main shaft (4) fixed to the housing (2);
- a driving unit (3) configured to comprise a mass body (31) capable of driving through the main shaft (4);
- an anti-rotation member (21) provided within the housing (2);
- a coil (5) and magnet (6) disposed at locations facing each other within the housing (2) and supplied with external power to generate a force that enables the driving unit (3) to perform a reciprocating motion;
- and
- one or more elastic members (7) disposed between the housing (2) and the driving unit (3) to transfer vibration.
