ABSTRACT:
The present invention provides a sounding apparatus with surface-mountable terminals, the sounding apparatus being capable of being automatically assembled onto a printed circuit board by the use of surface-mounting method. The sounding apparatus is formed by joining a molded housing including a pole piece and surface-mountable terminals to a container having sound emitting ports formed therein. A bobbin about which a magnet wire is wound is mounted on the pole piece of the housing and serves to actuate a vibrating plate spaced therefrom by a predetermined distance under the action of magnetic force. The bobbin includes bobbin terminals electrically connected with the terminations of the magnetic wire. When the bobbin is mounted on the pole piece, the bobbin terminals are brought into contact with the surface-mountable terminals on the housing so that the magnet wire on the bobbin will be electrically connected with the surface-mountable terminals.
