Document Type and Number:
Japanese Patent JP4573547
Kind Code:
B2
Abstract:
The speaker device has the pot type yoke and a frame. The pot type yoke has a body part and a bottom part, and is formed by connecting them. The body part has a flange part and projecting portions. Such a pot type yoke is made by connecting one inner peripheral edge portion of the body part and an outer peripheral edge portion of the bottom part. The pot type yoke is mounted to a frame. More specifically, the projecting portions formed on the top surface of the flange part are inserted into openings formed in the inner peripheral edge portion of the frame, and a lower surface of the inner peripheral edge portion of the frame is overlaid on a top surface of the flange portion. Then, the projecting portions are caulked by a caulking jig. Thereby, the pot type yoke is mounted to the frame. In the speaker device produced in this manner, the inner peripheral edge portion of the frame is disposed at the lower surface side of the pot type yoke. Therefore, the frame is entirely disposed at the side of the pot type yoke. Thereby, the distance from an upper end portion of the frame to a lower end portion of the put type yoke is reduced, and the speaker device can be made thin.
