Abstract

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.

Claims

1. An audio identification and distraction device adapted to be passed by law enforcement personnel through a window onto the floor of a structure subject to search and seizure, comprising:

a housing constructed at least partially of a material having a hardness to break a glass window at a low impact velocity, the housing having an elongated central portion, a speaker cap on one end to cover a speaker and protect it from impact, and a handle on the other end;

a voice message storage device in the housing having a police identifying message;

a battery operated power supply inside the housing;

an amplifier inside the housing to receive and amplify the output of the voice message storage device;

a speaker supported in the housing to receive the output of the amplifier circuit;

said amplifier and said speaker generating a high volume audio signal;

said voice message storage device, said battery operated power supply, said amplifier, and said speaker being mounted in the housing to withstand the shock of impact with said glass and said floor of said structure.

2. The invention defined by claim 1 where said audio signal output achieves a speaker volume of at least 100 decibels.

3. The invention defined by claim 1 wherein said speaker volume is a range from 110 to 112 decibels.

4. The invention defined by claim 1 which comprises a jack electrically connected to said battery pack and adapted for releasable connection with a recharging circuit.

5. The invention defined by claim 1 wherein said speaker has an axis coincident with a longitudinal axis of the housing, the speaker having an axial dimension and a diameter, the diameter being less than the axial dimension.

6. The invention defined by claim 1 further comprising a switch for activating the device to provide the audio signal, the switch being mounted to the housing adjacent the handle to allow a user to grip the handle and move the switch with one hand.

7. The invention defined by claim 1 wherein said speaker has a resonant cover.

8. The invention defined by claim 1 wherein said voice message storage device is a voice message storage chip, and said police identifying message is digitally stored within said voice message storage chip.

9. The invention defined by claim 8 wherein the housing has a longitudinal axis, a frame located within the housing having a bulkhead perpendicular to the longitudinal axis, and a rod parallel to the longitudinal axis and wherein the voice message storage chip is mounted to the frame.

10. The invention defined by claim 6 wherein said switch has a finger engaging portion and is mounted to the central portion of the housing and moves to an on position by pulling in a direction parallel to the handle.

11. The invention defined by claim 1 wherein the housing has a longitudinal axis, a frame located within the housing having a bulkhead perpendicular to the longitudinal axis wherein the voice message storage device is mounted to the frame, a rod parallel to the longitudinal axis and, and a speaker base perpendicular to the longitudinal axis, wherein the speaker is located on a first side of the speaker base and the circuit board is located on a second side of the speaker base between the speaker base and the bulkhead.

12. The invention defined by claim 1 wherein said housing is tubular and said handle is an elongated member extending coaxially from said housing.

13. The invention defined by claim 1 further comprising a user activated switch and a delay circuit to activate the power supply a selected time after activation.

14. An audio identification and distraction device adapted to be passed by law enforcement personnel through an opening and onto a floor of a structure subject to search and seizure, comprising:

a tubular housing having a longitudinal axis, first and second ends, and a speaker grid opening;

a speaker located in the housing adjacent to the first end, the speaker having a base with a diameter, an axis coinciding with the longitudinal axis and an axial length greater than the diameter;

a frame located within the housing having a bulkhead located at the second end of the housing perpendicular to the longitudinal axis and a rod parallel to the longitudinal axis and extending from the bulkhead to the speaker base;

a voice message circuit in the housing supported by the frame between the bulkhead and the speaker base and having a police identifying message stored therein;

a switch which when moved causes the voice message circuit and the speaker to deliver a loud message.

15. The invention defined by claim 14 further comprising a handle which is an elongated member extending coaxially from the housing.

16. The invention defined by claim 14 wherein the speaker grid opening is on the first end of the housing.

17. The invention defined by claim 15 further comprising a pin attached to the switch for activating the voice message circuit when the pin is pulled, the switch being mounted to the housing adjacent the handle and the pin having a finger receiving portion to allow a user to pull the pin as the device is passed through the opening of the structure.

18. The invention defined by claim 14 further comprising a delay circuit to activate the voice message circuit a selected time after activation by the switch.

19. A method for police audio identification and distraction comprising the steps of:

providing a device having a housing constructed at least partially of a material having a hardness to break a glass window of a structure at a low impact velocity;

providing a voice message storage circuit in the housing having a police identifying message;

providing a battery operated power supply inside the housing;

providing an amplifier inside the housing to receive and amplify the output of the voice message storage circuit;

providing a speaker supported in the housing to receive the output of the amplifier circuit;

mounting the voice message storage circuit, the battery operated power supply, the amplifier, and the speaker in the housing in a manner to withstand the shock of impact with the glass window and falling onto a floor of the structure;

breaking the glass window of the structure with the device;

dropping the device upon the floor; and

causing the device to output the message as a high volume audio signal.

20. A method for police audio identification and distraction of occupants within a structure having a glass window and a floor, comprising the steps of:

a) providing a device having a voice message storage circuit having a police identifying message, a battery operated power supply, and a speaker, all supported in the housing;

b) breaking the glass window of the structure with the device, passing the device through the window and allowing the device to fall onto the floor; and

c) actuating the voice message storage circuit, thereby causing it to provide the message and to identify the device as law enforcement personnel.

21. The method as defined in claim 20 wherein step c) occurs substantially simultaneously with step of breaking the window.
