摘要
In this electromechanical horn (T), which is provided with an acoustic diaphragm (5) able to undergo movements induced in it by variable magnetic fields generated by an electromagnet (3), the electromagnet (3) which operates the diaphragm (5) is excited by frequencies generated by an electronic oscillator which are based on the value of the maximum diaphragm resonance frequency measured by a specific sensor (7).
