An audio police identification and distraction device that is sufficiently rugged to be thrown inside a structure to be searched and deliver electronically a digitally stored, high volume voice message that clearly identifies the police or law enforcement agency and distracts persons inside the structure during a hard entry. The audio device includes a voice message memory chip, a rechargeable battery operated power supply, an amplifier, a speaker assembly and a user activated switch and delay circuit. The audio signal output can achieve a speaker volume of at least 100 decibels, preferably in the range of 110 to 112 decibels. The electronic components are contained in a hard housing that can be tossed through a glass window and onto a floor without damage. The audio electronic circuit is battery operated and mounted on a platform that is isolated from the impact shocks imposed upon the housing.
