    • A speaker includes an elongated diaphragm and a coupling member including forward and rearward segments, wherein at least two protrusions are provided at the rear side of the diaphragm along the major axis direction, the forward segment is engagingly disposed between the opposing end faces of two adjacent protrusions and also between the two portions of a rib of the diaphragm opposing each other in the minor axis direction, and wherein the outer circumferential surface of the voice coil bobbin is connected to the inner circumferential surface of the rearward segment, whereby the voice coil bobbin having a diameter larger than the dimension of the diaphragm measured along the minor axis direction can be successfully attached to the diaphragm. In the speaker described above, the diameter of the voice coil bobbin can be increased without decreasing the width of a surround thus enabling the withstanding of higher power input.
    • 扬声器包括细长的隔膜和包括前段和后段的联接构件,其中至少两个突起沿着长轴方向设置在隔膜的后侧,前段与两相邻的相对端面 突起,并且在短轴方向上彼此相对的隔膜的肋部的两个部分之间,并且其中,音圈骨架的外周面与后段的内周面连接,由此音圈线轴 具有比沿着短轴方向测量的膜片的尺寸大的直径可以成功地附接到隔膜。 在上述扬声器中,可以增加音圈筒管的直径,而不会减小环绕体的宽度,从而能够承受更高的功率输入。
