摘要：
A damper for a speaker for vibratably supporting a voice coil to a static part includes a first damper and a second damper formed in an annular shape having an inner periphery part and an outer periphery part, respectively. The first and second dampers are formed in a shape expandable and contractable in a direction crossing a circumferential direction of the annular shape. The inner periphery part of the second damper is connected to the first damper between the inner periphery part and the outer periphery part of the first damper, and each outer periphery part of the first damper and the second damper is connected to each other such that annular space is formed between the first damper and the second damper.
