A vehicular horn device of an existing electromagnetic type is used as a dynamic speaker so as to generate a false engine sound. The shortage of a low-pitched sound in a parametric speaker device is complemented with a false engine sound which the vehicular horn device generates. Thereby, without need of mounting a large-sized dynamic speaker such as a woofer in a vehicle, a false engine sound is generated so as to model for a real engine sound. In addition, as the vehicle approaches a pedestrian, a sound tone of the false engine sound which the pedestrian hears changes, enabling the pedestrian to easily notice the approach or presence of the vehicle.

Low frequency alarm tones emitted by life safety devices are more likely to notify sleeping children and the elderly. Disclosed herein is a life safety device equipped with a novel, compact, circumferential resonant cavity which increases the low frequency (400-600 Hz square wave) acoustic efficiency of an audio output apparatus formed by acoustically coupling an audio output transducer to the resonant cavity. The resonant cavity is a compact circumferential acoustic resonator with a captured mass of air within a ring shaped cavity significantly reducing the overall size of the resonator, thereby permitting the audio output apparatus to fit within the housing of conventional size life safety devices such as, but not limited to, residential and commercial smoke alarms and carbon monoxide alarms. The compact resonator is an acoustic compliant cavity with internal passages transforming axial traveling sound waves to circumferentially traveling sound waves thereby yielding a very compact geometry.

Disclosed is a reusable combination corrugated drinking straw and whistle. The drinking straw has an elongated tubular body with a fluid passage running therethrough. The tubular body is manufactured from metal (e.g., stainless steel) and has a plurality of corrugations extending radially outward therefrom. The tubular body is flexible and adapted to be bent so as to enable a user of the corrugated drinking straw to sip a beverage from a cup or the like. The corrugated drinking straw can also be used to produce an audible whistling sound when it is removed from the cup. The whistling sound is achieved when the user blows his breath against a blowing end of the drinking straw that is cut through one of the corrugations that extends radially outward from the tubular body. In this case, the corrugated drinking straw is wider at its blowing end than at the tubular body thereof.

A hand-held flinging device includes a launcher that engages the projectile and improves control of the launcher and projectile, during a throwing / flinging motion, until centrifugal force causes disengagement of the projectile from the launcher. The engagement system involves the rearward portions of a launcher shaft and the projectile bore, so that, upon disengagement, frictional engagement and interference of the engagement system with the projectile is prevented or limited as the projectile moves forward to fly off the launcher. The engagement system may include a member that snaps into engagement with a hole or recess to hold the projectile on the launcher even through the wind-up portion of the throw that may include the launcher distal end being pointed downward. The preferred projectile covers the entire or nearly the entire launcher shaft distal of the hand grip and is heavier toward its front end. Even though the launcher does not have a shaft or “stick” that is long relative to the projectile length, the flinging device gives enough mechanical advantage that a projectile that is large and heavy compared to conventional foam darts can be flung a long distance with accuracy and consistency.
