Abstract:
A circuit board includes an electrically conductive sheet having an insulative coating surrounding the conductive sheet, with a surface of the insulative coating around an edge of the conductive sheet having an arcuate or rounded shape. At least one electrical conductor is conformally deposited on at least the rounded insulative coating around the edge of the conductive sheet and defined via photolithographic and metallization techniques. Each electrical conductor on the insulative coating thereon around the edge of the conductive sheet conforms to the arcuate or rounded shape of the insulative coating and, therefore, has an arcuate or rounded shape.

Abstract:
A speaker device includes a speaker and a connecting component. The speaker has a pair of input terminals spaced apart with a first predetermined distance therebetween. The connecting component electrically couples the speaker to a printed circuit board. The connecting component has a relay-use printed circuit board and a pair of lead wires. The relay-use printed circuit includes a pair of sub-board portions and a separation portion. The sub-board portions have a pair of terminal holes. The input terminals of the speaker are disposed through the terminal holes, respectively. The separation portion is disposed between the sub-board portions to couple the sub-board portions with a second predetermined distance between the terminal holes of the sub-board portions, and selectively separate the sub-board portions when the first predetermined distance between the input terminals of the speaker is different from the second predetermined distance between the terminal holes of the sub-board portions.
