Abstract: For providing a printed circuit board, which can be miniaturized, and a speaker with the printed circuit board, and a method of manufacturing the printed circuit board, the speaker includes a speaker unit and a printed circuit board for supplying an audio current to the speaker unit. The printed circuit board has an insulation base board and a conductive circuit pattern formed on the base board. The conductive circuit pattern is formed of a base metal laminated on the base board and plated layers stacked on the base metal. An outer edge of the base board and an outer edge of the base metal overlap on each other. The outer edge of the base metal is covered by the plated layers.

Abstract: The speaker device includes a terminal electrically connected to an external circuit and a voice coil, and a frame for housing a speaker unit. The frame has a hooked protruding portion and a hole. The terminal has a contact point portion formed at one end and in contact with the external circuit, an insertion portion formed at the other end, a mounting portion mounted to a frame, and an opening formed at the mounting portion. At the time of manufacturing, the terminal is fixed to the frame by inserting the insertion portion formed at the terminal into the hole formed in the frame and inserting the hooked protruding portion formed at the frame into the opening formed at the terminal, and by relatively sliding the terminal and the frame to engage the inner peripheral edge portion of the opening with the hooked protruding portion.

Abstract: A connector for a speaker includes a box-shaped member having a block piece and an engaging member through which the box-shaped member is secured to a frame member of the speaker and a conductive wire in form of a coil spring having one end contacting a terminal provided for the frame member of the speaker and another one end projecting outward of the box-shaped member so as to contact a substrate of the speaker.
