Abstract

PURPOSE:To increase the characteristic of an electrostatic type pickup cartridge, by using induced N type electret constituent uniform in the surface charge density. CONSTITUTION:The 2nd metallic plate of an induced N type electret device 27 is opposed as a fixed electrode 34 to a moving electrode 33 supported to a cantilever 31 via a damper 32. On the other hand, an electret element 23 mounted with the 1st metallic plate 24 of the electret device 27 and the 1st metallic plate 24 itself is located at the back of the moving electrode 33.
