DESCRIPTION JPS5576595 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an enlarged sectional view of an essential part showing an embodiment of the present invention. 1 ...... stylus tip, 2 ...... cantilever, 3 ...... permanent magnets, 4 ...... damper rubber, 5 ······ sleeve, 6- ········································································· Pole piece DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic pickup cartridge. In order to accurately convert 1 ° 1 'y j 7' j "-J y ', Iti, FAH * mt to its electrical signal, its vibrating part 楚% 1' 142 min contacts other parts in the air It is held without. When the oscillator vibrates in air of low magnetic permeability, it has a process of electrically detecting the mechanical vibration of the oscillator comprising a permanent magnet by fluctuating the magnetic flux. The magnetic resistance of the magnetic path is increased, and the conversion efficiency for detecting the fluctuation of the magnetic flux is limited. The present invention eliminates the above-mentioned deficiencies and provides an electromagnetic type pink-up cartridge having a high output voltage and higher conversion efficiency. Hereinafter, the present invention will be described based on the illustrated embodiments. In the drawing, reference numeral 1 denotes a stylus tip that moves in accordance with the sound groove of the record, and is fixed to the tip of the cantilever 2. A cylindrical permanent magnet 3 is fitted and fixed to the other end of the cantilever 2 and is permanently magnetized in the longitudinal direction of the cantilever 2, and it grooves the vibrator. 4 is a ring-shaped damper rubber mixed with particles of high magnetic permeability material, the inner periphery of which is fitted with the outer periphery of the permanent magnet 3) and the outer periphery of which is fitted with the inner periphery of the snorve 5. 6 is an elastic support wire having one end fixed to the cantilever 2 and the other end fixed to the support + 11 '+ material 7. The support member 7 is fixed to the sleeve 5. A pole piece 8 detects a change in magnetic flux of the permanent magnet 3. With the above configuration, the damper rubber 4 in which particles of the high magnetic permeability material are mixed is disposed in the path of the magnetic flux generated by the 01-05-2019 1 permanent magnet 3, so that the magnetic flux generated by the permanent magnet 3 is efficiently changed. It is possible to realize large-scale electromagnetic pinotank cartridge resources. 01-05-2019 2
