Abstract

PURPOSE:To enhance both the frequency properties and the sensitivity as well as to realize a miniature size for the pickup by providing the piezoelectric film on the outer circumference surface of the cantilever and then providing the electrode film in 4 divisions on the piezoelectric film and in the circumference direction. CONSTITUTION:Piezoelectric thin film 12 is provided in the longer direction on the outer circumference surface of cantilever 10, and furthermore electrode films are provided in 4 divisions in the circumference direction on film 12. These electrode films are divided equally to be formed in such way that the divided parts having no electrode film may be located vertically to each other. In such constitution, opposing electrodes 13 and 15 of one side form a set of bimorphs holding lever 10 between, and as a result the electric output can be obtained from electrodes 13 and 15 to the bending vibration in the R-R direction of lever 10. In the same way, the electric output can be obtained from electrdes 14 and 16 to the bending vibration in the L-L direction of lever 10. Accordingly, if record stylus 11 is attached to these electrodes in the 45 deg. direction, a pickup for the stereo set can be obtained.
