【考案の詳細な説明】
本考案は表面に積層塗膜を施し、無用な振動を抑制した
トーンアームパイプに関するものである。[Detailed Description of the Invention] The present invention relates to a tone arm pipe whose surface is coated with a laminated coating to suppress unnecessary vibrations.
従来、トーンアームパイプの必要条件として、強度が大
であること、軽量であること、共振がないこと、外観が
美しいこと等が考えられる。Conventionally, the necessary conditions for a tone arm pipe include high strength, light weight, no resonance, and beautiful appearance.
特にカートリッジの針先で検出される振動の低域特性は
トーンアームによって大きく左右されるものである。In particular, the low-frequency characteristics of the vibrations detected at the tip of the cartridge are greatly influenced by the tone arm.
その為にトーンアームパイプの鳴きを抑える為、パイプ
内に樹脂を入れたもの、パイプ外周にゴムを巻きつけた
もの等があるが、まだまだ特性面でも不充分であり、モ
ーター其の他より伝播せる振動を抑制する制振材として
は不十分である欠点があった。For this reason, in order to suppress the noise of the tone arm pipe, there are some that put resin inside the pipe, and others that wrap rubber around the outside of the pipe, but they are still insufficient in terms of characteristics and the noise is more likely to be propagated than the motor or other parts. However, it has the disadvantage that it is insufficient as a damping material to suppress the vibrations caused by vibrations.
本考案は上記の欠点を除去する為に考案されたもので、
これを図面に示す実施例について説明すれば、第１図に
示す如く、トーンアームパイプ３の表面にポリウレタン
系樹脂等の、損失係数が大きい塗料１を塗布し、乾燥さ

グ率の高い塗料２を塗布して硬化させ、積層被膜を形成
せるトーンアームパイプである。This invention was devised to eliminate the above drawbacks.
To explain this with respect to the embodiment shown in the drawings, as shown in FIG. This is a tone arm pipe in which a coating material 2 having a high Young's modulus such as unsaturated polyester resin is applied and cured to form a laminated film.
本考案の制振材と従来の制振材たるゴム被膜の損失係数
の測定結果を下記の表に示すものである。The table below shows the measurement results of the loss coefficients of the vibration damping material of the present invention and the rubber coating, which is a conventional vibration damping material.
アルミニウム板のテストピースに各制振材を塗布し、温
度２０’Ｃ１湿度６２％で振動減衰率即ち損失係数を測
定したものである。Each vibration damping material was applied to an aluminum plate test piece, and the vibration damping rate, that is, the loss coefficient, was measured at a temperature of 20'C and a humidity of 62%.
８０Ｈ２に於て ５００ Ｈｚに於て
ゴム被膜 ０．００４９ ０．００４９本考案
積層被膜 ０．０６４ ０．０９上記の表に見られ
るように本考案積層被膜を形成すると、損失係数が０．
１近くになり、制振材としての効果が従来の制振材と比
較して格別に顕著である。At 80H2 At 500 Hz Rubber coating 0.0049 0.0049 Laminated coating of the present invention 0.064 0.09 As seen in the table above, when the laminated coating of the present invention is formed, the loss factor is 0.
1, and its effectiveness as a damping material is particularly remarkable compared to conventional damping materials.
第２図はゴム被膜を制振材に使用した場合、第３図は本

小さいものとなっている。Figure 2 shows the vibration characteristics when the rubber coating is used as a damping material, and Figure 3 shows the vibration characteristics when the laminated film of the present invention is used as the damping material. Characteristically, decarburization is small.
本考案は以上に述べたように、゛トーンアームパイプの
外周面に損失係数大なる塗膜層と、その上面にヤング率
の高い塗膜層を積層して形成すると云う巧妙な方法で振
動を抑制するもので、実用効果大なる考案である。As mentioned above, the present invention uses a clever method to reduce vibration by laminating a coating layer with a large loss coefficient on the outer peripheral surface of the tone arm pipe and a coating layer with a high Young's modulus on the top surface. This is a device with great practical effects.
