Abstract

A variable audio output buzzer includes a housing having a rotatable cap thereon. The cap has a varying width slot therein for cooperating with an audio output port in the housing to vary the sound level from the buzzer. The cap also has a projection for disposition within the audio output port in the housing during processing to seal the audio output port to prevent contamination during processing. A buzzer housing 1 has a retaining ring 2 molded in its top. The retaining ring 2 has an audio output port 3. During processing (solder and water wash), the audio output port 3 is closed by a projection 4 (Fig. 2) extending downwardly from a bottom surface 5 of a cap 6, which fits over the retaining ring 2 (Fig. 1). This prevents contamination of the buzzer within the housing 1 during such processing.

Variable Audio Output Buzzer Having a Seal for Protection Against Contamination During Processing

A variable audio output buzzer includes a housing having a rotatable cap thereon. The cap has a varying width slot therein for cooperating with an audio output port in the housing to vary the sound level from the buzzer. The cap also has a projection for disposition within the audio output port in the housing during processing to seal the audio output port to prevent contamination during processing. A buzzer housing 1 has a retaining ring 2 molded in its top. The retaining ring 2 has an audio output port 3. During processing (solder and water wash), the audio output port 3 is closed by a projection 4 (Fig. 2) extending downwardly from a bottom surface 5 of a cap 6, which fits over the retaining ring 2 (Fig. 1). This prevents contamination of the buzzer within the housing 1 during such processing. After processing, the cap 6 is rotated so that the projection 4 (Fig. 2) is positioned within an arcuate recess 7 (Fig. 1) in the top of the retaining ring 2. In this position of the projection 4 (Fig. 2), the cap 6 (Fig. 1) has a slot 8 of varying width overlying the audio output port 3 in the retaining ring 2. Thus, rotation of the cap 6 through approximately 180 degrees provides a varying output from the buzzer in the housing 1 since the open portion of the output port 3 in the retaining ring 2 is varied. The position of the slot 8 in the cap 6 relative to the audio outpu...
