Abstract: A water sports nasal guard prevents unwanted contaminated water from entering a user's nostrils. The water sports nasal guard includes a mouth guard, an upper tongue shield, a lower tongue shield, and a nostril shield. The mouth guard allows the user to bite down on the water sports nasal guard, thereby upholding the nostril shield against the nasal passages of the user. The nostril shield presses up against the openings of the user's nasal passages. The mouth guard further includes an arch-shaped body, an upper teeth receptacle, and a lower teeth receptacle. The arch-shaped body positions the upper teeth receptacle and the lower teeth receptacle opposite to each other, both of which accommodate the upper teeth and lower teeth of the user. The upper tongue shield and the lower tongue shield prevent the user's tongue from coming between the teeth of the user and the mouth guard.

Abstract: The “Venturi Didgeridoo” or “Reverse Didgeridoo” is a musical instrument played in the manner of a didgeridoo (i.e. with an “unvoiced linguolabial trill” made by loosely vibrating or “fluttering” lips). It consists of one or more venturi chambers in which the diameter of the mouth opening (proximal end) is greater than the diameter of the opening at the distal end (in novel contrast to the construction of any other end-blown musical instrument). This tapered tube constitutes a venturi chamber in which the velocity of air is increased at the point of greatest constriction and in which internal pressure is increased at the point of greatest diameter. This unique acoustical design creates pitches that are much lower than those possible in traditional didgeridoos of equal length. A sequence of several separate venturi chambers consisting of graduated cylinder sections of diminishing diameter will result in an extremely compact, collapsing (telescoping) instrument.

Abstract: A noisemaker assembly that includes an annular horn body having an inner wall, an outer wall and a groove disposed there between. The groove is open at the top surface of the horn body. A tubular mouthpiece is provided that extends into the horn body. The mouthpiece communicates with the groove inside the horn body. When air is blown into the mouthpiece, that air passes into the groove within the horn body. A membrane is placed over the horn body so that the membrane covers the top of the groove. When air is blown into the groove, the air slips past the membrane from inside the groove. This causes the membrane to vibrate and generate a loud low frequency noise. The horn assembly can be held within a housing. The housing has perforations to enable sound energy from the horn assembly to escape from the housing.

Abstract: The marking system for musical instrument reeds uses one or more marks placed (e.g., printed, engraved, embossed, etc.) on the blunt end of a musical instrument reed, opposite the thin, vibratory portion of the reed. These markings indicate the grade or relative stiffness of the reed, i.e., its resistance to vibration when the instrument is played. The markings of the system correspond to the conventional Arabic numeral system used to indicate the grade of reeds, but the present markings are placed upon the blunt end of the reed where they are visible when the reed is installed in the instrument mouthpiece or when the reed is in storage in a typical reed holder. One or more marks are placed toward one side of the blunt end of the reed to represent integers, while a single mark is placed to the opposite side (when required) to indicate half values.

Abstract: A duck call for reproducing the sounds made by certain whistling ducks without having to flutter the tongue comprising a main body, a mouthpiece frictionally connected to the main body and a tubular roller disposed in a central sound chamber located in the main body of the whistle. Air blown by the user enters the open end of the mouthpiece and passes through an air vent on the mouthpiece into the central sound chamber. A slot formed at the interface of the end of the mouthpiece and an air vent in the main body creates a whistle sound that is directed into the sound chamber to rotate the tubular roller to produce the vibrato effect necessary to emulate the whistling-type ducks. A pair of side members having air chambers therein can be connected to the main body to create a larger resonant chamber in which the roller rotates. Apertures at the closed end of the side members can be open or closed by the user's fingers to selectively produce sounds that mimic other whistling-type ducks.

When held between the thumbs and blown on by mouth, the ribbon harp vibrates in the audible frequency range and produces a musical note. The player may vary the tension in the ribbon in order to vary the fundamental frequency with which the ribbon harp vibrates, thus producing higher or lower pitches. Various methods may be used to provide lengthwise strength. Dampening properties can be tuned by varying properties in the crosswise direction. Aerodynamic surface treatments are provided so that the ribbon harp commences to vibrate immediately on being blown across. A wrist harness or gauntlet and a thumb cot are described as aids to the player.

Abstract: A motion-activated musical device is disclosed which sounds harmonic overtones of a longitudinal resonator. Swinging the device causes the formation of a pressure differential across the device. This pressure differential causes air to flow through the longitudinal resonator, initiating an oscillation in the hole tone resonator. A standing wave is then established in the longitudinal resonator in response to this oscillation and a musical tone results. Variations in motion cause the device to sound a sequence of harmonically related musical tones.

Abstract: A hybrid electronic and acoustic musical instrument whose main section has an animal-like form, such as that of a cat or dog. Extending from the rear of the main section is a hollow tail section terminating in a mouthpiece and provided with a series of finger holes whereby the tail section functions as a recorder instrument. A series of push-button switches mounted on the animal-like body of the main section is connected to a Read-Only-Memory (ROM) housed in this body. Digitally stored in the ROM is a series of different recorded sounds similar to those which the animal represented by the main section is capable of producing, such as barks or meows but in quasi-musical form. When a particular push-button switch is depressed, the related digitally-stored sounds are read out of the ROM and converted to an analog signal which is amplified and reproduced.
