Abstract:
The purpose of the present invention is to provide a small and thin linear oscillator which has the characteristics of a linear oscillator capable of quick response and which has a motion part that does not slant and is capable of stable rectilinear motion along a support shaft. A linear oscillator according to an embodiment of the present invention may comprise: a coil having a predefined space formed in the inside thereof; a permanent magnet which is disposed inside the coil and generates oscillation power by interacting with the coil; a bearing which is coupled to both ends of the permanent magnet and forms, together with the permanent magnet, a motion part; a support shaft of which, in the cross section thereof, the major axis and the minor axis have different lengths and which is disposed so as to penetrate through a portion of the bearing; a bracket for supporting both ends of the support shaft; and an elastic member of which one side is supported by the motion part and the other side is supported by the bracket, thereby amplifying the oscillation power.
