    • A speaker of the present invention includes the following: a diaphragm that includes an inner periphery coupled to a voice coil, and a corrugation provided at the intermediate position between the inner periphery and an outer periphery; a speaker edge for supporting the outer periphery of the diaphragm; and a damping member attached to an outer peripheral part of the diaphragm outside the vicinity of an outer periphery of the corrugation. The effective vibration area of an inner peripheral part of the diaphragm inside an inner periphery of the corrugation is substantially half or less of the total effective vibration area. The damping member is configured as a damping portion by extending an overlap portion of the speaker edge overlapping with the diaphragm to the vicinity of the outer periphery of the corrugation. This configuration can suppress the vibration transmission at high frequencies to the outer peripheral part of the diaphragm outside the corrugation, allows only the inner peripheral part of the diaphragm inside the corrugation to mainly vibrate at high frequencies, and also can suppress a resonance in the outer peripheral part of the diaphragm outside the corrugation. Thus, the speaker can have both an excellent high frequency response and an excellent mid-high frequency response.
    • 本发明的扬声器包括:隔膜,其包括耦合到音圈的内周和设置在内周与外周之间的中间位置处的波纹; 扬声器边缘,用于支撑隔膜的外周; 以及阻尼构件,其附接到所述隔膜的外周部分在所述波纹的外周附近。 波纹内周内的振动膜的内周部的有效振动面积大致为总有效振动面积的一半以下。 阻尼构件通过将扬声器边缘与隔膜重叠的重叠部分延伸到波纹的外周附近而被构造为阻尼部分。 这种结构可以抑制波纹外部的隔膜的外周部的高频振动传播,仅允许波纹内的隔膜的内周部分以高频率主要振动,并且还可以抑制外部的共振 隔膜的外围部分在波纹外面。 因此,扬声器可以具有优异的高频响应和优异的中高频响应。
