PURPOSE: A method for manufacturing a magnetic buzzer is provided to simplify a manufacturing process and decrease a manufacturing cost and time by stably designing an inner structure. CONSTITUTION: A stick(13b) is pressed with a base(13a) by one body for manufacturing a yoke(13). The yoke(13) is combined with a lower case(12) in which a stepped difference groove is formed at one side by one body. A coil(14) is wired on a circumference surface of the stick(13b) so that both sides of the coil(14) are inserted into the stepped difference groove of the lower case(12). A magnet(15) is located at an edge of the coil(14). A vibrating plate(16) is fixed to an upper surface of the magnet(15) for converting a current signal into a sound signal. An upper case(12) in which a sound exhausting hole(11a) is formed is combined with an upper side of the lower case(12).
