Claims

[Scope of utility model registration request]

A core and a coil are disposed inside the housing, and the armature disposed within the housing is fixed to a diaphragm and a sounding plate attached to the opening of the housing, and the armature is attracted by the magnetic force of the coil, and the armature is moved. In an electric/pneumatic tone generator equipped with an interrupter that interrupts the current in the coil, a printed circuit board with a conductive film formed on both sides of an insulating plate is electrically connected between the conductive films on both sides. A resistor for noise prevention is fixed, and the printed circuit board is arranged between a support member having a fixed side contact and a spring member having a movable side contact, and the insulation between both contacts prevents noise. 1. An electric alarm, characterized in that it is equipped with a current interrupter configured to connect a resistor for prevention.
