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.

Abstract: A frame is provided with an opening allowing insertion of a jig for setting an inner rim of a suspension holder to a proper position. The jig ensures positive alignment of the suspension holder when making connection to the frame. The jig also ensures reliable bonding of a diaphragm to the suspension holder with a bonding agent, since it steadily supports the suspension holder in position during the bonding process. The positioning of the bobbin and a voice coil is thus reliable when being assembled, thereby improving acoustic performance of a speaker.
