本考案はレコードプレーヤのインシュレータに係り、特
に振幅の大きい振動を速やかに減衰させることができる
インシュレータに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insulator for a record player, and particularly to an insulator that can quickly damp vibrations with large amplitude.
従来のインシュレータを第１図、第２図に示す。Conventional insulators are shown in FIGS. 1 and 2.
インシュレータ１はゴムなどの弾性体からなり、環状の
肉厚部２と、その肉厚部２の内側にそれと一体に形成さ
れた肉薄部３とを備え、肉薄部３の内側部分がビス４に
よりキャビネットの裏板５に連結されている。The insulator 1 is made of an elastic body such as rubber, and includes an annular thick part 2 and a thin part 3 integrally formed inside the thick part 2. It is connected to the back plate 5 of the cabinet.
肉厚部２の下端面には、リング６が接着されている。A ring 6 is bonded to the lower end surface of the thick portion 2.
前記肉厚部２は、主に床振動の伝播を弱める働きをして
いる。The thick portion 2 mainly functions to weaken the propagation of floor vibrations.
前記肉薄部３はその撓みの大きさを利用して、振幅の大
きい振動の伝播を弱めるために設けられている。The thin portion 3 is provided in order to weaken the propagation of large amplitude vibrations by utilizing the magnitude of its deflection.
ところが、インシュレータ１がゴムなどの弾性体で作ら
れているとはいえ、振幅の大きい振動を肉薄部３で速や
かに減衰させることは難しい。However, even though the insulator 1 is made of an elastic material such as rubber, it is difficult to quickly attenuate large-amplitude vibrations with the thin wall portion 3.
そのためレコードプレーヤの近くを人が歩いたり、プレ
ーヤやそれを載置している台に触れたりして大きな振動
を受けると、針飛びや混変調歪を発生する。Therefore, if a person walks near the record player or touches the player or the stand on which it is placed and receives large vibrations, stylus skipping and cross-modulation distortion occur.
またレコードの偏心や反りなどにより、７Ｈｚ程度まで
振動成分が含まれ、一方、プレーヤの共振周波数が１０
Ｈｚ近くにあるから、演奏時にコーン紙が大きく振れ、
そのため再生音が歪ぼく聞こえる。Also, due to eccentricity or warping of the record, vibration components up to about 7 Hz are included, while the player's resonance frequency is 10 Hz.
Since it is close to Hz, the paper cone shakes greatly when playing,
As a result, the playback sound sounds distorted.
インシュレータの硬度を上げれば共振周波数が高くなり
、コーン紙を大きく振動させることはなくなるが、可聴
帯域内でのハウリング現象が大きくなる。Increasing the hardness of the insulator increases the resonant frequency, which prevents the paper cone from vibrating significantly, but increases the howling phenomenon in the audible band.
本考案は、このような従来技術の欠点を解消し、振動を
速やかに減衰させることのできるインシュレータを提供
するにある。The object of the present invention is to provide an insulator that can eliminate the drawbacks of the prior art and quickly damp vibrations.
次に本考案の実施例を第３図、第４図を用いて説明する
。Next, an embodiment of the present invention will be explained using FIGS. 3 and 4.
第３図に示すように、キャビネット７の裏板５の各隅に
はインシュレータ８が取り付けられている。As shown in FIG. 3, insulators 8 are attached to each corner of the back plate 5 of the cabinet 7.
インシュレータ８はゴムなどの弾性体で作られ第４図に
示すように、下端面にリング６を固着した環状の肉厚部
９と、その肉厚部９の内周側に一体に設けられ環状溝１
０を有する肉薄部１１と、その肉薄部１１のほぼ中央に
立設され裏板５に穿設されたインシュレータ取付孔１２
と係合して先端に先細状の貫通端１３を有する支え部１
４とが一体に設けられている。The insulator 8 is made of an elastic material such as rubber, and as shown in FIG. Groove 1
0 and an insulator mounting hole 12 erected approximately at the center of the thin wall portion 11 and drilled in the back plate 5.
A supporting portion 1 having a tapered penetrating end 13 at its tip and engaging with the supporting portion 1.
4 are provided integrally.
前記貫通端１３の裏板５の上面と接する部分には、抜は
止め用のっぽ部１５が一体に形成されている。A tab 15 for preventing removal is integrally formed in a portion of the through end 13 that comes into contact with the upper surface of the back plate 5.
前記支え部、１４は比較的肉厚に設計され、環状のフェ
ルト製制動部材１６が外嵌され、肉厚部９の上面内周側
には制動部材１６を支承するための突提１７が設けられ
ている。The support portion 14 is designed to have a relatively thick wall, and an annular felt braking member 16 is fitted onto the supporting portion 14. A protrusion 17 for supporting the braking member 16 is provided on the inner peripheral side of the upper surface of the thick portion 9. It is being
リング６を肉厚部９に固着し、制動部材１６を支え部１
４に外嵌したインシュレータ８を、その貫通端１３を先
にして裏板５のインシュレータ取付孔１２に挿入し、貫
通端１３を裏板５の上面側へ引くと、貫通端１３のつば
部１５の所までが押圧変形されながら取付孔１２を貫通
する。The ring 6 is fixed to the thick part 9, and the braking member 16 is attached to the support part 1.
4 is inserted into the insulator mounting hole 12 of the back plate 5 with its through end 13 first, and when the through end 13 is pulled toward the upper surface of the back plate 5, the collar 15 of the through end 13 is removed. It passes through the attachment hole 12 while being deformed by pressure.
するとつば部１５と支え部１４との間のくびれ部分が取
付孔１２に嵌合した形でインシュレータ８が裏板５に取
り付けられ、制動部材１６は裏板５と肉薄部１１との間
に介在され、その上面が裏板５に下面が肉薄部１１にそ
れぞれ当接される。Then, the insulator 8 is attached to the back plate 5 with the constricted part between the collar part 15 and the support part 14 fitting into the mounting hole 12, and the braking member 16 is interposed between the back plate 5 and the thin part 11. The upper surface thereof is brought into contact with the back plate 5, and the lower surface thereof is brought into contact with the thin portion 11, respectively.
この実施例のように、インシュレータ８の上端につば部
１５を有し裏板５の取付孔１２に貫通する貫通端１３を
設けておけば、裏板５へのインシュレータ８の取付けが
簡便である。As in this embodiment, if the insulator 8 has a flange 15 at the upper end and a through end 13 that penetrates through the mounting hole 12 of the back plate 5, the insulator 8 can be easily attached to the back plate 5. .
特にフェルト製の制動部材１６を用いれば、洋毛などの
繊維が機械的にからみ合っているから、繊維どうしの摩
擦抵抗、クッション作用により、振動の吸収効果が非常
に良好である。In particular, if the braking member 16 made of felt is used, since fibers such as western wool are mechanically entangled, the vibration absorption effect is very good due to the frictional resistance and cushioning effect of the fibers.
さらに実施例で述べたように、肉薄部１１の中央に、上
部が裏板５と当接する支え部１４を設けて、それにより
制動部材１６が荷重で押しつぶされて硬くなるのを防止
すれば、制動部材１６に適正な接触圧が与えられ、常に
安定した制動効果が発揮できる。Furthermore, as described in the embodiment, if the support part 14 whose upper part contacts the back plate 5 is provided in the center of the thin part 11, thereby preventing the braking member 16 from being crushed by the load and becoming hard, Appropriate contact pressure is applied to the braking member 16, and a stable braking effect can always be exhibited.
本考案は前述のように、インシュレータの肉薄部とキャ
ビネットの裏板との間に制動部材を介在させることによ
り、振幅の大きい振動を速やかに減衰させることができ
、針飛びや混変調歪の発生が解消され、防振性の優れた
インシュレータが提供できる。As mentioned above, by interposing a damping member between the thin part of the insulator and the back plate of the cabinet, this invention can quickly damp vibrations with large amplitudes, which can cause needle skipping and cross-modulation distortion. This eliminates the problem and provides an insulator with excellent vibration-proofing properties.
