Description
【考案の詳細な説明】
本考案は、ピックアップに釦けるヘッドシェルの構造に
関するものである。[Detailed Description of the Invention] The present invention relates to the structure of a head shell that is attached to a pickup.
従来、ヘッドシェルの材質として、軽金属やプラスチッ
クなどいろいろあるが、強度が大きく、軽量でかつ振動
損失の大きなものが望ましい。Conventionally, head shells have been made of various materials such as light metals and plastics, but it is desirable to use one that is strong, lightweight, and has a large vibration loss.
その為に一般にア″ミ０ウハマグネシウム及びカーボン
繊維を合成樹脂中に含１れているものが使われている。For this purpose, a synthetic resin containing aluminum and magnesium and carbon fiber is generally used.
しかし上記３項目は同時に満足するものはない。However, none of the above three items can be satisfied at the same time.
又セラミック単体のみで構成すると、強度が大きく、軽
量なものができるが、共振の鋭度が非常に大きくなって
しオい、高音域限界周波数が高くなり、高音域で複雑な
共振を起す恐れがある。Also, if it is made of only ceramic, it can be made strong and lightweight, but the sharpness of the resonance will become very large, and the upper limit frequency will become high, which may cause complex resonance in the treble range. There is.
本考案は、上記の欠点を除くために考案されたもので、
図面に示す実施例について説明すれば、第１図に示すご
とく、セラミックの球形中空体と、これとほぼ同じ熱膨
張係数を有するセラミックとを混在させ、球形中空体セ
ラミックをセラミックで包埋させた構造のへラドシェル
である。This invention was devised to eliminate the above drawbacks.
To explain the embodiment shown in the drawings, as shown in Fig. 1, a spherical hollow ceramic body and a ceramic having almost the same coefficient of thermal expansion are mixed, and the spherical hollow ceramic body is embedded in the ceramic. It is a helad shell of structure.
これは温度、湿度にきわめて安定しており、ヤング率は
アルミニウムに比較して非常に優れている為、非常に剛
性の強いシェルがつくられる。It is extremely stable in temperature and humidity, and its Young's modulus is much better than that of aluminum, creating an extremely rigid shell.
球形中空体セラミックで構成されているので、共振鋭度
を少くすることができる。Since it is made of spherical hollow ceramic, the resonance sharpness can be reduced.
表面がダイヤモンドに次ぐ硬さを有する。Its surface has a hardness second only to that of diamond.
本考案は、以上のような材質で構成されてしるので、こ

感が出て、音質の向上に格段の効果を上げるものである
。Since the present invention is constructed from the above-mentioned materials, when using this head shell, it produces a firm sense of weight in the bass range, as well as a clear sense of transparency in the treble range. This has a significant effect on improving sound quality.
本考案は、以上に述べたようにヘッドシェルの構造が球

に改善させた、ヘッドシェルを提供するものである。As mentioned above, the head shell structure of the present invention uses an ingenious method of embedding a spherical hollow ceramic body in ceramic, resulting in extremely high strength, extremely light weight, and low resonance sharpness. This product provides a head shell that dramatically improves sound quality.
第１図は本考案のへラドシェル断面図。 １は球形中空体セラミック、２はセラミック。 Figure 1 is a sectional view of the herad shell of the present invention. 1 is a spherical hollow ceramic, and 2 is a ceramic.
