A damper for a speaker capable of operating with both a high compliance and a low compliance is obtained. The damper for a speaker includes a first and a second dampers (11, 12) that are formed in an annular shape having an inner periphery part and an outer periphery part, being formed in an expandable and contractable shape in a direction crossing the circumferential direction of the annular shape, and the inner periphery part of the second damper (12) is connected to the first damper between the inner periphery part and the outer periphery part of the first damper (11), and each outer periphery part of the first damper (11) and the second damper (12) is connected each other such that annular space (S) is formed between the first damper (11) and the second damper (12), and a plurality of expandable and contractable curved parts (11c) are formed in the first damper (11) at least from the connecting point of the inner periphery part of the second damper (12) to the inner periphery part of the first damper (11) in a direction crossing the circumferential direction. |
