PURPOSE: A coin-type oscillator having a wave-like vibration generating structure is provided to reduce the complexity of a structure by using DC(Direct Current) power applied from a system. CONSTITUTION: A panel(110) is a cylindrical plate type and provided with a coupling projection on a center of an upper surface thereof. A first electromagnet(120) is formed on a curve-shaped core, adhered to an external side of the upper surface of the panel(110), and generates magnet force by a DC current supplied from a system. At least two first contact points(130) are separated from and fixed on an upper surface of the first electromagnet(120) and the first contact points(130) is electrically connected to a coil of the first electromagnet(120). A second electromagnet(140) is formed on the curve-shaped core in the form of a wound coil, adhered to an external side of the upper surface of the panel(110), generates magnet force by the DC current supplied from the system. At least two second contact points(150) are separated from and fixed on an upper surface of the second electromagnet(140) and the second contact point(150) is electrically connected to a coil of the second electromagnet(140). An oscillating body(160) is provided with opposing semicircular metal plates(161,163) connected by a support(165) and the support(165) of the oscillating body(160) is hinge-coupled to a coupling projection(111) of the panel(110). A case(170) has a lower portion with an opened cylindrical type and is coupled to the panel(110).
