本発明は、ダストカバーの上面の振動を防止するダスト
カバー防振装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust cover vibration isolating device that prevents vibrations on the upper surface of a dust cover.
第１図は、従来のレコードプレーヤ等のダストカバーを
示したものであるが、上面が広い平面となっているため
、アンプ等の音量をあげるとダストカバー１の上面が振
動し、アコ−ステイクフィードバック、いわゆるハウリ
ングが起き易いという欠点があった。なお、２は飾りバ
ッジである。Figure 1 shows a conventional dust cover for a record player, etc. Since the top surface is a wide flat surface, when the volume of an amplifier, etc. is increased, the top surface of the dust cover 1 vibrates, causing acoustic noise. The drawback was that feedback, or so-called howling, was likely to occur. Note that 2 is a decorative badge.

装置を提供するものである。In order to eliminate the drawbacks of the above-mentioned conventional example, the present invention provides a dust cover vibration isolating device for record players, etc., which prevents vibrations with a simple configuration by attaching a weight to the dust cover. It is.
以下、図面によシ実施例を詳細に説明する。Hereinafter, embodiments will be described in detail with reference to the drawings.

で弾性爪６が元に戻シ、おもシ４の離脱が防止される。FIG. 2 shows an embodiment of the present invention, in which numeral 3 is a dust cover, and a recess 3a into which a weight 4 is inserted is formed approximately in the center of the upper surface of the dust cover. Reference numeral 5 designates a retaining pin provided in the center of the recess 3a, which engages with a hole 4a provided in the weight 4 when the weight 4 is inserted into the recess 3a. A plurality of elastic claws 6 are provided near the peripheral wall of the recess 3a, and when the weight 4 is inserted into the recess 3a, the elastic claws 6 are pushed outward and expanded as shown in FIG. The elastic claw 6 returns to its original state with the rice pad 4 housed, thereby preventing the rice pad 4 from coming off.

イザとしても使用することが可能である。By the way, if the hole 4a of the weight 4 is made to engage with the spindle of the turntable, it can be placed on top of the record when playing the record, and can also be used as a record stabilizer.
以上説明したように、本発明によれば、簡単な構成でダ
ストカバーのハウリングを抑えることができ、安心して
アンプの音量を上げることができる。As described above, according to the present invention, howling of the dust cover can be suppressed with a simple configuration, and the volume of the amplifier can be increased with peace of mind.
