Rubber &c. pads D, D1 are provided between the receiver and the base A and bar A2 respectively. The diaphragm C<1> of the receiver, which may either be of magnetic material or of non-magnetic material with an armature secured thereto, is in adjustable contact with the end of a screw B4 threaded through the upper end of a stylus bar B2 which is carried on a bracket arm B secured by screw B1 to the base A. According to a modification, the base A may be formed as a cup-shaped member, the receiver C being held therein by radial screws.
