The present invention is a portable air horn apparatus including: a housing; an air horn assembly for generating sound, the air horn being mounted in the housing and receiving air from a small tank. An internal pump fills a small inline tank by means of a one way valve, and a release button sends the air through a diaphragm through the air horn. The air supply of the inline tank is rechargeable by means of an internal hand operated pump, in order to maintain the necessary supply of air required to produce adequate sound.

The present disclosure describes speech or sound-emulating bottle cap apparatuses and systems and methods for manufacture thereof. It will be understood that a bottle cap prohibits gases from escaping a pressurized bottle. Ordinarily, when the cap is removed from the bottle, the escaping gas will emit a sound, but the sound carries no discernable meaning, cognizable message or recognizable sound (aside from gas simply escaping a pressurized container). Embodiments described herein harness gas escaping from a bottle (when the cap is removed) to generate a discernable meaning, cognizable message or otherwise recognizable sound. The sound-chamber may be wrapped or twisted into a coil or helix shape (in addition or as an alternative to miniaturizing it). A coil or helix shape permits recovery of the original sound quality of the initially modeled sound-chamber, resulting in “a sound-emitting cap-chamber” removably or permanently coupled to a bottle cap or bottle as described herein.

An adaptive electropneumatic horn system include an acoustic sound wave generator including an acoustic duct chambering system. The Acoustic sound wave generator receives compressed air remotely from a compressor member to produce sound and propagate the same externally. A horn mounting system enables ready attachment and fitment of the system to a remote consumer-desired location and is adaptive to constraining geometries and locations greatly spacing the acoustic sound wave generator from the compressor member, and as a result a plurality of fitment features provided in the horn mounting system allow positioning to a user's preference, within increased safety and reliability. An adaptive mounting bracket member additionally securely receives the air compressor unit.

A sound producing device includes at least one air pulse generating element. Each of the at least one air pulse generating element includes a membrane, a first air chamber and at least one opening, wherein a chamber pressure exists in the first air chamber, and the opening is connected between the first air chamber and an ambient surrounding the sound producing device. The membrane is actuated to change the chamber pressure of the first air chamber to generate a plurality of air pulses, the air pulses are propagated through the at least one opening, the air pulses produce a non-zero offset in terms of sound pressure level, and the non-zero offset is a deviation from a pressure value of an ambient pressure outside the sound producing device.
