Title:
SPEAKER
Document Type and Number:
Japanese Patent JP2005123663
Kind Code:
A
Abstract:

To provide a speaker having improved its acoustic characteristics.

An opening 15 provided in a frame 12 enables the insertion of a jig 24 for setting an inner peripheral portion of a suspension holder 13 at a regular position. As this result, stable positioning can be performed in coupling the suspension holder 13 with the frame 12, and in the next step the joining of the suspension holder 13 can be stably performed because the suspension holder 13 is stable in joining and fixing a diaphragm 9 via a fixed body 14. Accordingly, the positions of a bobbin 8 and a voice coil 7 to be fixed are stable, and thus preventing deterioration in the acoustic characteristics of the speaker.
