DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pickup cartridge
vibration system, and is a book for maintaining an appropriate angle of a needle tip and realizing
an appropriate record performance. Conventionally, when constructing a vibration system using
a cylindrical magnet, not only the internal shape but also the outer shape is round (1) f? Although they were held together by a joint having a complete end, they were likely to shift in
the circumferential direction due to the relationship with the damper, resulting in a major
inconvenience in the record playing. The present invention is proposed to solve this problem, and
in detail, according to the drawings, in the vibration system constituted by the reproduction
needle cantilever, the armature, the damper, etc., the central axis of the cantilever 3 and the
cylindrical magnet 4 The gist is that the outer peripheral surface of the joint 1 which is arranged
linearly and held so as to be continuously contained is a quadrilateral 2 having an arbitrary
number of surfaces extended in the longitudinal direction of the vibration system. 2.) The joint 1
is configured as a circular through cylinder adapted to hold and hold the cylindrical magnet No.
and cantilever 3 inside, and clamps and holds them. Although this joist 1 is made to be purchased
and supported by the damper 6, in the present invention, since the outer peripheral surface of
the joist 1 is a polyhedron 2, by making the support contact portion of the damper 6 conform, (2)
is completely prevented from rotating around the inside of the damper 6 in the circumferential
direction. That is, if the holder has a round outer surface as in the prior art, it rotates in the outer
peripheral direction in the damper, causing a shift, and the shift once generated can not be
restored to the proper state. The company also has the effect of suppressing the inertial force in

the puncturing movement state, which is of course the company's deviation from the left and
right direction of the regenerating needle. カフ8□tAj、:に!。 □, 1, the regeneration
needle 5 can not be positioned on a vertical line from the center point of the cut lever 3, and the
regeneration needle 5 performs a so-called wage movement exercise according to the action of
the force. Since the magnet 4 is located on the central axis of the cantilever 3 as shown in FIG. 3
due to this swinging motion, an amplitude amount is generated only for the amplitude B of the
cantilever 3, but the reproducing needle 5 amplitudes for the amplitude A. (1) The rise
characteristic is bad, and the pan (2) increases, (3) the dynamic range narrows, (4) ji! The wave
number causes disadvantages such as a large number of (3) phase shifts and (5) deterioration of
the strok. In the drawings, it is needless to say that the outer shape of the holder 1 is a
polyhedron which is a square, but it is not particularly limited.
The present invention overcomes these drawbacks and can realize proper record playing, but this
effect is equivalent to a square pole magnet used to produce the same effect, and has the same
mechanical effect. It works. In addition, the cost of using a square pole magnet can be halved. As
described above, according to the present invention, it is possible to provide a vibration system
capable of realizing appropriate record keeping by maintaining the proper angle of the
reproduction needle at a low cost.
