A vibration motor is disclosed. The vibration motor includes a housing, a substrate engaging with the housing, a vibration unit received in the housing, an elastic member suspending the vibration unit, and a coil assembly interacting with the vibration unit. The vibration unit includes an avoidance corresponding to the coil assembly for preventing the vibration unit interfering with the coil assembly.

The present invention relates to a reciprocating switched reluctance motor-driven engine in which a crank shaft is rotated by the switched reluctance motor and which is configured to reciprocate according to the reluctance torque generation principle of the switched reluctance motor. More specifically, an SRM module (1) is composed of: a cylindrical stator (11) obtained by coupling two stator cores (111) which have, on the inner surfaces, stator salient poles (1111) that are excited by winding coils (112); and a mover (12) which has mover salient poles (1211) formed on the outer surface and can reciprocate inside the stator (11). The mover (12) is coupled to a crank mechanism (2) for converting the reciprocating motion of the mover (12) into rotational motion, and rotational force is output from the crank mechanism (2) by the mover (12) which is reciprocated by alternatingly exciting the two stator cores (111).

This vibration transmitting device comprises: a vibrating actuator which causes a movable body, which is supported in such a way as to be capable of vibrating elastically with respect to a fixed body, to vibrate by driving the movable body in one direction of the vibration direction of said movable body; and an accommodating unit for internally accommodating the vibrating actuator. The accommodating unit has an opening portion exposing at least a portion of the movable body such that the movable body comes into contact with an object to which vibrations are to be imparted, and the vibration transmitting device is provided with a projecting portion which projects from the movable body to the exterior of the accommodating unit through the opening portion.
