Abstract
An anti-burglary sound emitting device in which a pressurized fluid is discharged to audibly oscillate a diaphram to create a warning signal when an intruder opens a window or door to enter an area unauthorized to the intruder. The anti-burglary device employs a spring biased pressurized container for discharging a fluid through a passageway and diaphram valving structure. A mechanical trigger for releasably retaining a pressurized container in cocked position and for releasing the slidably mounted pressurized container to cause sound is described.
