Abstract
An electric piezo mic for pick-ups, which is essentially characterized in that the vibrating needles that contact the slots of the disc are two sapphires, each of which is mounted at the end of a support sheet bent in a helix on itself and solidary, through a joining plate that joins the two supporting lamellae of the sapphires, with the piezo-electric vibrator.
