Abstract
Supporting and contacting means for supporting a disk-like piezoelectric tone transducer on a circuit board comprises a pair of sheet metal supporting members which are mounted on the circuit board in spaced-apart planes which extend normally of the plane of the circuit board. The supporting members are connected by solder tabs to conductors on the circuit board and have opposed re-entrant notches on their upper edges. The transducer is mounted in the supporting members by positioning its circular edge in two corresponding notches, flexing the supporting members and then locating the edge in the remaining notches of the supporting members so that the transducer is engaged at four locations on its periphery. Electrical contact is maintained with the ceramic material of the transducer by means of a spring contact arm mounted on the circuit board between the supporting members.
