A connecting device for a sound generator comprising:
- a pair of connecting spring plates (2),
- each of the connecting spring plates comprising a base end connecting portion (2A) which is bent into an L-shaped form comprising a lower horizontal portion and an upwardly inclined portion and secured to a terminal of the sound generator (1) at an underside of the lower horizontal portion, an intermediate portion (2C) extending from an upper end of the connecting portion (2A), a branch portion (2D) outwardly extending from the end of the intermediate portion in a plane same as the plane of the intermediate portion so as to form an L-shape together with the intermediate portion, an overlap portion (2E), and a head end connecting portion (2B) extending from said overlap portion,
- the overlap portion (2E) being formed by turning an end portion of the branch portion in U-shape,
- the head end connecting portion (2B) being turned into a U-shape for connection to a terminal of an outer circuit by pressing the head end connecting portion against the terminal;
- a surface of the base end connecting portion being coated with gold by gold plating;
- a surface of the head end connecting portion being coated with gold by gold plating, and
- said coating with gold by gold plating being limited to the base and the head end connecting portions.
