Abstract: An spray shield for an aerosol canister. Embodiments include a shield body constructed of a flexible sheet material. The shield body can generally define an arc of a circular ring and present a fixation mechanism, wing slots, and notches. The shield body can be rolled to form a frustum of a cone having a wide front opening and a narrower rear opening including a cutout. The shield body can be removably fixed in a conic configuration through engagement of tabs and tab slots. A retaining clip can comprise a semi-circular head adjoined by legs which meet wings at neck portions. In use, retaining clip can be engaged around a collar of an aerosol canister. Assembled shield body can be removably affixed to canister via retaining clip. Spray shield can direct particulate aerosol matter sprayed from a canister in a forward direction, and provide protection from environmental or other factors.

Abstract: This disclosure provides for an auditory modification apparatus to facilitate extraction of information from an auditory observation stream. The approach may be used to reveal features about the environment, or to simplify processing of the incoming audio stream. The apparatus acts on the incoming auditory stream by nature of its shape, and that shape either is passively static or actively manipulated. Preferably, the apparatus has given shape characteristics to reveal features of the environment, such as directionality of a noise, size of an enclosed space, or materials of its construction, that are not otherwise detectable or easy to process with conventional approaches. Further advantage exists in the notion of actively manipulating the shape of the apparatus in conjunction with its operation to facilitate information extraction in a dynamic manner.

Abstract: A water safety flotation device includes a buoyant body and a hollow core. The buoyant body has a length and a width, with the length defining a longitudinal axis of the device. The hollow core extends along the longitudinal axis of the body. The hollow core is substantially conical and provides a first opening in the body at a first end and a second opening in the body at a second end. The hollow core serves the function of a megaphone.

Abstract: A sound amplifier is provided in the form of a sound amplification cone with a front panel opposite a rear panel and spaced apart by side panels. The side panels fold so that the front panel and rear panel can collapse together or be deployed apart. The sound amplification cone is hinged to a tab which is held at least partially within a case. The case also holds a smart device therein. A slot in the case allows for the tab and sound amplification cone to slide into and out of the case when the cone is collapsed. When the sound amplification cone is slid out of the case and deployed, a port of the sound amplification cone is located adjacent speakers of the smart device to amplify sound therefrom. Auxiliary speakers and a power source can also be provided within the tab or sound amplification cone for further sound amplification.

Abstract: A voice amplification assembly includes a plurality of rings movably coupled to one another so said rings may form a megaphone.

Abstract: A collapsible megaphone device having a body portion capable of lying flat in a first state and capable of assuming the shape of a megaphone in a second state where in the first state, the collapsible megaphone device is substantially two dimensional and planar having a first edge, second edge and boundary edges joining the first and second edges. The collapsible megaphone device is convertible from the first state to the second state by exerting pressure against its boundary edges and is returnable to the first state by removing pressure from its boundary edges.

Abstract: A megaphone comprises a rigid but bendable material with a tapered shape. When the material is folded, the produced megaphone has a small opening at one end and a larger opening at the other end. The megaphone has edges that form an opening along the side such that when pressure is applied to the edges the opening expands allowing the megaphone to be positioned on a person's arm or leg. Once positioned on the arm of leg the rigidity of the material causes the megaphone return to its original cone shape. The megaphone can enclose around a user's arm or leg for storage purposes during an event. Information can be displayed on the surface of the megaphone. The megaphone of the present invention can be folded and unfolded.

The cup has a side wall with overlapping first and second side edges that are attached to one another. An end cap at least partially seals the second end. The end cap is vertically offset from the second end toward the first end and is formed with the side wall as a single, continuous piece of material.

Abstract: A method of mounting a speaker enclosure for a ceiling or wall mounted speaker which includes the selection of a flexible polymer speaker housing forming a hollow chamber having a speaker opening therein and being collapsible to a smaller size. A hole is cut into a building, ceiling or interior wall and a selected speaker housing is collapsed to a size to fit through the speaker opening in one side of a ceiling or wall. The collapsed flexible polymer speaker housing is then expanded on the other side of the ceiling or wall and attached to the ceiling or wall with an adhesive or the like adjacent the opening and a speaker attached to the ceiling or wall opening.

Abstract: A portable sign which can be used at sporting or other events that doubles as a megaphone formed from a flexible sheet of dry erase material cut into the shape of a “baseball field”—having two opposing, elongated sides, an upper arced edge and a complimentary lower arced edge.

Abstract: A new megaphone cup for providing a device that is convertible between a drinking cup and a megaphone. The inventive device includes a base having upper and lower surfaces with a tubular cup mount upwardly extending from the upper surface of the base. The cup mount has a lumen and an upper opening into the lumen. Removably inserted into the lumen is the bottom end of a cup member. The top and bottom ends of the cup member both have openings into the cup member hollow interior and the cup member is also tapered towards the bottom end of the cup member. When the cup member is detached from the cup mount, a user may shout into the opening of the bottom end to use the cup member as a megaphone. The cup member also includes an extendable portion which is retractably extendable between an extended position and a retracted position.

Abstract: A cup is readily converted to an acoustic megaphone by removal of the base. The paper construction, enabled by the features of the invention, offers a good printing surface and simultaneously ensures that the cup is biodegradable. In a first embodiment, a removable tape seal is used to releasably seal and retain a cup bottom to cup side walls. In a second embodiment, a more permanent seal is provided, along with a tear cord. Other embodiments illustrate pull tabs, handles, and a releasable adhesive. The base may also only be partially separated, thereby opening the cup into a horn, while still retaining the base to reduce the amount of waste paper which may become scattered.

Abstract: An acoustic horn assembly for use as part of an electronic siren system for an emergency vehicle comprises a pair of integrated molded, rigid plastic members which cooperate to define a pair of divergent sound passages. The entrance ends of these sound passages are displaced do that they may be coupled to separate sound generators, the sound generators being supported from respective vehicle frame side rails. The sound generators are coupled to the sound passage entrance ends by adjustable length sound transmission conduits which are in the form of elbows.

Abstract: A megaphone is formed from a self-supporting flexible plastic sheet. The sheet is wrapped with overlapping side edges to form a horn shaped member. The overlapping edges are releasably interlocked by edge slots and interconnecting edge arms. A separate mouthpiece has a tube which telescopes into the narrow mouth end of the horn and has an outer shaped end for coupling to the user's lips. The plastic sheet may be rolled into a compact tubular roll. The mouthpiece is placed over the roll to maintain the rolled configuration for storage and transport. The horn sheets can be readily mass produced by stamping and the mouthpiece by molding.
