Abstract
A piezoelectric type pickup cartridge comprises a cantilever, an intermediate member deformable in two orthogonal directions, a press member secured to the other end of said cantilever and adapted to transmit the movement of the cantilever to the intermediate member, a piezoelectric transducing element, a damper provided between the element and the base for holding the piezoelectric element between the intermediate member and the damper.
Claims7
A piezoelectric type pick-up cartridge comprising a cantilever having one end mounting a stylus and the other end connected to a base member by a wire, an intermediate member deformable in two orthogonal directions mounted on said base member adjacent the point of connection of said base member and said wire, a press plate means secured to the other end of said cantilever and in contact with said intermediate member for transmitting the movement of said cantilever to said intermediate member, a piezoelectric transducing means for generating electric signals in response to the deformations thereof mounted on said base member and positioned to abut the intermediate member on a side thereof opposite to the side of said intermediate member which contacts said press plate means, a damper means mounted on said base member and on said piezoelectric transducing element, said piezoelectric transducing element being tightly positioned between said damper means and said intermediate member, whereby vibration of said stylus is transferred to said piezoelectric element via said cantilever, said press member and said intermediate member.
