Loudspeaker with a suspension member made of a laminate

摘要

An outer marginal edge of a loudspeaker cone is connected to an annular suspension member of laminated structure which supports the loudspeaker cone on a support frame. The annular suspension member includes a layer of cloth and a first layer of flexible plastic foam integrally bonded to the cloth. The first layer of foam has an inner surface in contact with the outer marginal edge, and the cloth covers an outer surface of the first layer of foam opposite to the inner surface. A second layer of foam which is thinner than the first layer of foam is disposed between and bonded integrally to the cloth and the first layer of foam. The suspension member is strong and durable and still exhibits good formability and flexibility.
