3. Detailed Description of the Invention The present invention relates to the novel structure of
the town rss magnet type pickup. In the following, the details of the invention will be explained
based on the drawings. FIG. 1 shows a cross-section of the tl) -vibrator part of the stereo pickup
according to the present invention, which is fixed to a support 1t31 made of a light material such
as a plastic 12). The magnets (5a, 5b) supported by the magnet support portion (4) are fixed to
the support portion + 311c. 7 (, tel wire one end of which is a wire fixed to the hook 11 portion
of the canna lever (2), and the wire 161 supporting portion (3), the dasher (7), the three 7 '(8)
After 11 holes in the inner hole, it is pulled to the opposite side of the needle tip with a constant
pressure, and the other end is identified in the sleeve 181. Accordingly, the damper -171 taEE
compression force is received, and the fulcrum of the vibrating yarn is set near the center of the
support portion 181. The principle of power generation of the pickup using the vibration exciting
portion configuration will be described. Referring to FIG. 2, the U-shaped magnet supporting
portion (4 in FIG. 1) is also shown on the upper surface of the above supporting portion (3). Of
the pair of magnets (5a, 5b) in the magnet support portion (4) such that the pair of magnets (4a
and 5b) are perpendicular to the axis of the cantilever 121 and both magnets (saMab The
opposite faces of the) are arranged so that the polarities of the opposite faces are different from

each other, and a constant distance is maintained between the magnets (5a, 5b). Then, both of
the ring-shaped magnetic cores (gear of $ 1, EndPage: 1 part 110) are placed in a plane
perpendicular to the resistance of the magnets (5a, 5b) against the resistance of the magnets (5a,
5b). Magnets (5a) and (5b)-are inserted, and − = t, magnetic b, (5a) and (5b) e to rH1 surface is
different, so that the magnetic flux is distributed across one facing surface However, the gap
Jflail is inserted into this magnetic flux. In this case from 1 to 2 in total (1) as in the second layer

total III is 1111 in the same ■ T, the magnetic core (91 (I) point has a south pole. (B) N is close
to the point, and the same (a magnetic flux flows in the magnetic core 191). Therefore, if the
sound needle + 11 vibrates in the direction of O · 10,000. As a result, a voltage is generated in
the winding f121 which has been subjected to the spring 1 o 1 in the magnet L) 191. In addition,
it is needless to say that the total (vibration in the case of vibration of 11: U is determined in the
middle and in the vicinity of the support 31 as described above), However, in the case of
playback of stereo record 11111'L, "7.

111 (5a) and (5b) sigma on the side of 戊嬰 1 boron 114 (B)-(n ′) are positioned symmetrically
with respect to the line axis. Further, during the vibration 10 required to be obtained in the
support portion (3), an intersection O of the 11 ti I axis of (A)-(A ') and (B)-(G)-1 (o)-(a') is
assumed. そして。 The gap between the magnets (aa) and (5b) of the% ill 041 is entered into the
4 parts <1 market of 421% between the magnets (aa) and (5b) of the respective components
required. Incidentally, although only the side of the light-emitting element D 141 shown on the
side of the light-emitting element D 141 is shown on the 4331 flame 1, it is needless to say that
the same thing is applicable to (瀉 1 戊 requirement f + 3) flQ +. (A)-(A ') 1 If the same vibration is

L occurs in the magnet 10 (9) on the component ■ side. An electrical signal is taken out of the
winding 1121. Similarly, when vibration in the (B)-(BY direction) occurs, a rotational movement
in which the (A)-(A ') line 1 # I is set to 0 (4) occurs, and an electrical signal is taken out. 7c,
Cross talk is triggered by key rotation, +4 = 1 bit is taken out (b) Rotational speed / inhibition is
caused by the flux catabolism, but 1 reciprocity vs. U 磁石 j Since only the parallel bar is inserted
to the gap portion, no sigma flux line formation occurs in the magnetic core, and hence no
electrical signal distortion occurs. As described above, it is possible to provide a pick-up device
that can perform unreliable and bamboo-like structure for the 1 st No. 1 g reproduction and
perform reliable reproduction. 4 · 1 s 1 s commercial description □ · dl taste 1 trx In the cross
