摘要： A diaphragm and a speaker unit which can prevent generation of abnormal sound by suppressing rolling phenomenon. The speaker unit has a diaphragm. The diaphragm includes a portion for supporting a voice coil, and a sound emitting portion formed continuously to one end thereof. The voice coil supporting portion has a shape extending reversely to the sound emitting direction. The sound emitting portion includes a step portion having a surface substantially perpendicular to the sound emitting direction, and a bent portion having a cross-section bent toward the inside of the voice coil supporting portion from one end of the step portion. Consequently, the voice coil supporting portion is movable to describe an arc having a radius substantially equal to the radius of curvature at the bent portion of the voice coil supporting portion and a basic point substantially identical to the center of the bent portion in the bending direction as the voice coil moves in the sound emitting direction or in the reverse direction. Rolling phenomenon can thereby be retarded, the voice coil supporting portion can be prevented from colliding against a magnetic circuit when the speaker unit is driven and generation of abnormal sound can be prevented.
摘要翻译：隔膜和扬声器单元，其可以通过抑制滚动现象来防止产生异常声音。扬声器单元具有隔膜。隔膜包括用于支撑音圈的部分和连续地形成在其一端的声音发射部分。音圈支撑部具有与声音发射方向相反的形状。声音发射部分包括具有基本上垂直于声音发射方向的表面的台阶部分和从台阶部分的一端朝向音圈支撑部分的内侧弯曲的横截面的弯曲部分。因此，音圈支撑部分可移动以描述具有与音圈支撑部分的弯曲部分处的曲率半径基本相等的半径的弧形，以及与弯曲方向上的弯曲部分的中心基本相同的基本点当音圈在发声方向或相反方向移动时。由此可以延迟滚动现象，可以防止当扬声器单元被驱动时音圈支撑部分与磁路碰撞，并且可以防止产生异常声音。

摘要： A speaker device includes a diaphragm having an inner rim connected to a voice coil bobbin and an outer rim connected to a frame through an edge, wherein the diaphragm is shaped so that a peak portion is formed with an acute angle folded back between the inner rim and the outer rim which are positioned at an acoustic radiation side in comparison with the peak portion. The cross-sectional shape of the diaphragm extending from the peak portion to the inner rim is formed with a convex shape toward an acoustic radiation side, and also that of the diaphragm extending from the peak portion to the outer rim is formed with substantially straight shape or convex shape toward the acoustic radiation side. The speaker device lower in profile allows high-quality sound to be reproduced, in particular, the high range of frequency characteristic of the sound pressure to be improved.
