Abstract

An electromagnetic coil and plunger mechanism is used to strike a resonating bar or bell. It can be driven by an oscillator or by a self-oscillating circuit. The mechanism has a coil (12), a magnetic plunger (14) with an extension (15). The extension (15) is used to strike a resonating bar (10). The coil (12) is connected to a battery through a push-button switch (21) and a reed switch (22). One end of the plunger (14) has a permanent magnet (28). Displacement of the plunger (14) releases the reed switch (22) and de-energises the coil (12). The reed switch (22) closes and re-energises the coil. A cyclic movement of the plunger (14) and a repetitive striking of the bar (10) are obtained.
