Improvements introduced in the phono-reproductive heads for phonographic apparatuses, characterized by constituting the sensitive element of sound reproduction, based on an elongated sheet of electrical-electrical material, which is joined in its middle part, a block of a shock-absorbing material. Vibrations, which makes contact by its upper and lower faces, with the box and cover respectively of the envelope of said element, which also bears at one end, a thick flexible ring that keeps in position the two electrical terminals, being inserted by the other end in the transmission part of the mechanical solicitations of the follower tip.
