Abstract: A damper, which is an element of a speaker and suppresses the rolling of a voice coil unit, includes a corrugated structure portion at its inner periphery and a leaf spring at its outer periphery. By coupling the corrugated structure portion to the voice coil unit and coupling the leaf spring to the frame, the distortion of a speaker can be reduced and the driving efficiency can be improved.

Abstract: In a speaker, a first space enclosed by the surface of a second edge close to a magnetic circuit body, a suspension holder, the outer circumferential surface of a voice coil body, the magnetic circuit body, and a frame is airtight to the atmosphere outside the speaker, to make a first space function as an air suspension. The voice coil body is supported with a first edge and a second edge, and with the aid of the springiness of gas inside a first space. Hence, an equivalent, low Young's modulus can be set to the first edge and the second. Consequently, deformation of the diaphragm connected to the first edge is reduced during sound reproduction, thereby reducing disturbance in frequency response in the middle and high ranges.
