[Detailed Description of the Invention] This invention relates to a completely movable valve-type
mechanism having a 1 to 1 [moving magnet type vinoqua asopcar torinono, characterized in that
it has an 8-shaped fixed structure. By including a magnet also in the magnetic assembly, the
voice conversion efficiency is significantly improved. 1−o4.p f? Conventionally, an Eshaped core, such as a convex-gravity-magnet-type bino guan Noop Car Torino, which is a child
of the 11th year, has an auxiliary magnet (141 [facing eye e! 1), or 2) solidify the cantilever S-3
with 2 months' livelihood on the moving magnet 1's 10] magnetized in the thickness direction,
(1) shadow 111k, damper There is a vibrating thread that is swingably supported by 4 and
Saspernon Yon wire 5, and 1ull1JJli of the town magnet l! This is a pair of E-shaped Goaroo with
1 pair. The coil IO is inserted between the center hole 7 of the E7 core and when the movable
magnet is moved by 1L from the record 箭 as shown in Fig. 2 (A), as shown by the dotted line,
The temple mff 7 i 1-ball 8-se / tar pole 7 is formed, and the coil 10 has 1 monarchy. When it is
swung as shown in FIG. 2 (b), it is possible to use a right and left ball as a moving ball right lcenter ball 7-pole 9, and the coil 10 is reversed. However, in the above-mentioned conventional
device, there are only 6 bundles of m1 stone,
m1 stone,
6, and so on. Therefore, the
output power generated by the coil is small and the conversion torque is low. Therefore, he used
expensive magnets. The purpose of this device is to improve the disadvantages of +1

conventional devices, 0J! l! The point is to significantly increase the conversion efficiency of
the 171 magnet type pickup. Referring to FIGS. 3 and 4, we will explain the first offering 1 of this
invention. (Same part number with the same sign is the same as the whole table f)-, Vibration
yarn and its support 1 The temporary structure is Takumi Yoneta and Takumi Yori. The
difference from the conventional wages-1 is that the E'-shaped core 60 is provided instead of the
E-shaped core 60, and the structure is such that the end of the T7-shaped core 12 has different
magnetic contacts with the rod magnets 13.14. The ring is formed into a figure of eight, and the
coil 10 is wound on a 120-piece core of a D-shaped core. 1. The signal from the record groove is
blanched, and as shown in FIG. When in position, there is no output at coil 10, but if the @
magnetic right moves sideways as shown in Fig. 5 (A), the town @ magnet l-magnet 13-T shaped
smaller in front of the point The magnetic flux of the LIJ moving magnet 1 and the magnetic flux
of the magnet 13 are superimposed on the coil IIJ so as to be detected, as shown in FIG. 5 (b).
Then, the casting path of the movable magnet 1-T-shaped core 12-magnet 14 is formed, and the
coil 10i This is the movement of the tumbling stone type pick-up and the movement of the town
movement piece pino guanozoo, so to speak, this is a retrograde 11 in which the flux and the
magnetic flux of the magnet 14 are superimposed. And a large, non-. 61 large output can be
obtained.
For example, the E-shaped magnetic part may be purchased 1 · − (only the above-mentioned one
and only one, and if it is 1 × 11, as shown in FIG. -It may be of ruby 17 ° 1 g, a monotonous
grade * l of l9. The supporting structure of the vibrating yarn does not necessarily support both
of the "open" moving magnets, but may support, for example, the side lII of the moving magnet. .
As explained above, this consideration is a completely successful separation, and the conversion
efficiency of the moving stone type pickup is [′ ご め め 、 、 、 効果 効果 効果 効果 4− 4−
There is something.
