CONSTITUTION: The tolling system for the stone bell comprises: a miniature bell(1) for ringing real sound; a bell strike bar(2) striking the stone bell(5) to rebound to ring the miniature real bell housed in the bar(2); a mike(3) for catching the ringing sound of the bell(1); a speaker or an amplifier(4) for producing the bell ringing received in the mike; a dummy stone bell(5) housing the speaker and the amplifier; a sensor and a chip for sensing the bell strike to retrieve the recorded bell ringing for delivery.
