    • A speaker includes a frame, a diaphragm disposed in a top end of the frame of the speaker and a bobbin disposed below the diaphragm. A voice coil is wound around a bottom end of the bobbin and a magnetic member, which has a groove in which the bottom end of the bobbin around which the voice coil is wound, is inserted and reciprocated in a straight line upward and downward. A central pillar is fixed to the magnetic member at a center of the bobbin and extends parallel to the movement of the bobbin. A damper supports an inner circumferential surface of the bobbin from the central pillar. The damper additionally supports an outer circumferential surface of the bobbin, from the frame, so as to allow the bobbin to reciprocate in a straight line. This results in minimization of wobble and distortion, so that accurate sound is generated.
    • 扬声器包括框架,设置在扬声器的框架的顶端的隔膜和设置在隔膜下方的筒管。 音圈缠绕在线轴的底端,磁性构件具有一个槽,在该槽中绕着绕线圈的绕线筒的底端以一直线向上和向下插入和往复运动。 中心支柱固定在线轴的中心处的磁性构件上,并平行于线轴的运动而延伸。 阻尼器从中心支柱支撑线轴的内圆周表面。 阻尼器另外从框架支撑筒管的外圆周表面,以便使筒管以直线往复运动。 这导致摆动和失真的最小化,从而产生准确的声音。
