Principles and Applications of Electromagnetic Beehive

Electromagnetic honeycomb is a common electronic component, usually used for output alarm, wake-up call and other functions. Unique vibration piece, spiral tube and tank composition, simple and easy to use. Under the action of external applied voltage, the magnetic field generated by the current passing through the spiral tube, the magnetic force generated by the iron core on the spiral tube can be used, and then use its vibration. Vibration induced single resonance on fixed iron core, and voice wave generated. Applications for electromagnetic beehives include gates, trains, security systems, intelligent homes, etc. Especially when there is a small demand for sound effects, such as police cars, fire trucks, rescue trucks, etc., the electromagnetic beeper can be used in urban areas.
