Electro-dynamic speaker

摘要

Provided is an electro-dynamic speaker having a unique damper extending between a coil bobbin carried by the inner periphery of a diaphragm and a frame carrying the outer periphery of the diaphragm. Due to the provision of the unique damper, a satisfactory compliance along the axis of the bobbin and a favorable regulating force against radial deforming force are obtained, to ensure a good linearility of the force-displacement characteristics of the speaker in the low frequency range even during vibration at a large amplitude.
