SPEAKER COMPONENT USING THERMOPLASTIC CARBON FIBER RESIN BASE MATERIAL AND SPEAKER

To provide a speaker component which has a high vibration damping effect and passes well over a wide range with good sound, a method of manufacturing the same, and a speaker.SOLUTION: A material of a speaker component is constituted of a thermoplastic carbon fiber resin base material composed of a composite material containing a thermoplastic resin and carbon fibers. The composite material has a loss factor of 0.025 or more, and contains 5-60 wt.% of the carbon fibers. The ratio of carbon fibers with a carbon length of 0.01-0.5 mm is 60 wt.% or more in all carbon fibers, and 15% or more carbon fibers are set along concentric circles.SELECTED DRAWING: None 【課題】振動減衰効果が高く、広範囲に渡り音の良く通るスピーカー用部品およびその製造方法、並びにスピーカーを提供する。【解決手段】熱可塑性樹脂および炭素繊維を含む複合材料からなる熱可塑性炭素繊維樹脂基材から構成されると共に、複合材料の損失係数が０．０２５以上かつ、前記炭素繊維を５重量％～６０重量％含有し、全炭素繊維中、繊維長が０．０１ｍｍ～０．５ｍｍである炭素繊維の割合が６０重量％以上で、かつ同心円に沿って１５％以上の炭素繊維が設定された素材。【選択図】なし
