BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side sectional view of a conventional
vibrator, and FIG. 2 is a side sectional view of a vibrator according to the present invention. 1 и и и и
retention Damper, 7 иии Composition.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vibrator which
engages with the recording sound of a pickup cartridge, and in the case of a vibrator which holds
the end of the cantilever with two elastic holding edges, the definition of the vibration supporting
point is There is to get. ??? FIG. 1 is a side sectional view showing an example of a
conventionally used vibrator, showing a movable magnet type. The needle lever 3 is planted at
one end and the permanent magnet 2 is fixed at the other end. One end of the holding wire 4
made of an elastic material such as copper steel wire is fixed to the axial center on the side
having the permanent magnet 2 The end is fixed to the holder 5. A damper 6 made of a flexible
material such as rubber is interposed between the permanent magnet 2 and the holder 5, and the
axial center of the holding wire 4 # 'i damper 6 is penetrated. The vibration of the needle 1
related to the recording sound groove uses the holding wire 4 for holding the cantilever 3 as a
vibration fulcrum, and the vibration is exposed at the axial center of the damper 6 Since the
deflection over the entire length of the line 4 is the fulcrum, the vibration which is different from
the vibration with one point as the fulcrum becomes a complicated vibration, and the reproduced
sound tends to lack clarity. Therefore, the present invention is improved to be a substantially
one-point fulcrum such as the swaying vibration fulcrum of the conventional holding wire 4. FIG.
2 is a cross-sectional view of a vibrator according to the present invention. The overall
configuration is the same as that of FIG. 1, but in the construction of the holding wire 4, an
appropriate position of a portion serving as a flexible fulcrum in the conventional example of FIG.
A V-shaped or U-shaped incised groove 7 is provided on the outer periphery. Therefore, since the
diameter of the holding wire 4 is narrowed at the cut groove 70, the cut groove 70 can naturally
be bent more clearly than other exposed portions in the vibration state. When the shape of the
same incised groove 7 is V-shaped, it becomes clearer than the U-shaped at the fulcrum position
i1 grain, but depending on the material of the holding wire 4, the fatigue cutting rate may be
high. It may be U-shaped. In addition, the movement of the permanent magnet 2 is ideal when
the cutting position of the cutting rod 7 is closer to the permanent magnet 2 side, but there is
also a conflict with the damping of the damper 6, and empirically within the spatial position It is
decided. As described above, according to the present invention, in the shaft hole V of the
damper 4 of the holding 4 holding the peristaltic rod such as the canna lever 3 (a part of the part
to be encased is v-shaped or U-shaped cut # 7 By providing the vibrator, the vibrator has a clear
peristaltic fulcrum and contributes to the improvement of the reproduction capability. The same
idea is shown as an example and of course a moving magnet type. It can be used in any of the
vibration type 1 in which one end of the force / tire is held by the above-mentioned elastic
holding line 1 such as a movable wire ring type or Q variable reluctance type.
