DESCRIPTION JPS4910501
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an example of a
conventional piezoelectric ceramic cartridge, FIG. 2 is an explanatory view showing a partially cut
piezoelectric ceramic cartridge according to the present invention, and FIG. It is a frequency

(-1- J'D "/, Yata 101 summer (1) A1- and A! -Due to the influence of the transmission loss of
modulation power and the change of response due to temperature due to the cuff and O rubber,
and the addition of the mass, the reproduction band is considerably affected, and the
reproduction band is short; Therefore, in particular, the resonance frequency is broadened and
the high frequency band characteristics are broadened, and the amount of transmission
information is increased by 71 members; Now, an example of a conventional piezoelectric pickup cartridge will be described with reference to FIG. 1. The ceramic vc 1... (I%, ',' iAi ? needle 2?

is self-evident It is clear that the influence of T cantilever 1 and R-71 near 4 and evening / pagum

The present invention is a piezoelectric type Vikara 1 cartridge, which is a shield different from
the conventional one such as Knee, as described above according to the present invention.

the force / clever itself is piezoelectric J! Also, the mass under the needle tip can be made small,
and it is less likely to receive ? ? ? ? due to the armature or danbagono, and the solid wave
number characteristics, feeling, etc. are improved, as shown in the 31st 4th. As a matter of fact,
the reproduction frequency can be broadened by setting the oscillation frequency to l?1 for
high-pitched sound. This band is determined by the next resonance frequency, ie, the resonance
of the mass of the needle tip and the stay 7ness of the piezoelectric J'-f, the quality of the
