Abstract

An alternating current electric buzzer comprising a coil 13 wound about a spool 16 and encapsulated by insulation 17 of nylon or the like and attached to a mounting bracket 11 provided with a vertical leg 25 carrying a clapper 24, is provided with a polepiece 21 having an inclined face 23, the polepiece being rotatable to vary the effective air-gap and thereby vary the intensity of the sound. In the arrangement shown in Fig. 2 a spring arm 31 is mounted on the lower end of the polepiece and is provided with an embossment 33 adapted to engage one of a number of recesses provided in the bracket 11 to lock the polepiece in a desired angular position a slot 30 is provided in the pole-piece to allow it to be rotated. Stops limit the maximum rotation of the polepiece to 180 degrees. In a modification, Fig. 4 (not shown), the lower part of the polepiece is provided with a flange formed with an indexing lug adapted to engage a selected recess in the bracket 11, and a spring clip (49) engages shoulders formed on the upper part of the pole-piece to bias the indexing lug towards the recess the lower part of the polepiece is extended to form a shaft on which may be mounted a knob or lever for rotating the polepiece. The buzzer is suitable for use with a washing machine or a dryer to indicate the end of a particular cycle.
