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