ABSTRACT:
A pickup stylus is secured to a plastic stylus holder at one end thereof by inserting it into the holder in a direction that bears a desired, non-perpendicular angle in respect of the longitudinal axis of the stylus holder. The one end of the stylus holder is provided with a surface which is disposed at right angles to the direction of stylus insertion into the holder in order to reduce the possibility of stylus misalignment and mislocation. The stylus holder has a cutout which is shaped and dimensioned such that the resonance frequency of the stylus holder is located near the upper end of the audible frequency range. The stylus holder, which has these and other features, is not only simple and inexpensive, but also has the desired performance characteristics.
