Abstract: A wind instrument such as a harmonica has a mouthpiece with one or more air channels, an electric power source, and a means for generating an electrical output signal from strain gages exposed to airflow in the channels. First and second strain gages having variable flow-induced resistance are bonded to a flexible substrate and suspended within an air channel, which includes a divider shelf for directing a first airflow to the first strain gage and a second airflow to the second strain gage. Complimentary strain gages are mounted to an opposite side of the substrate for inverse flexure to enable temperature correction for the first and second strain gages. When a user forces air through a channel in a direction biased to one side of the divider shelf a difference signal is generated by the first and second strain gages and detected by comparing their outputs.

Abstract: A wild game call has a single inlet passage into which a user blows to generate sounds that simulate the natural sounds produced by the particular animal being called or attracted. The call includes a splitter that splits the single air inlet passage into a plurality of outlet passages. The sound either is generated in the single air passage or passes into the single air passage from the user and is directed into the plurality of outlet passages to produce the final output sound from the call. The plurality of outlet passages can be configured to produce subtle differences in the sound passing through a passage to provide a combination of sounds more closely simulating the natural animal sound than can be produced in only a single outlet passage. Various sound chamber can be added to the outlet passages to modify the sound emanating from that passage in a desired manner.

Abstract: A musical instrument capable of producing the sound spectrum associated with a traditional Australian didjeridoo, but in a more compact and portable form. In certain embodiments, an air column follows a tortuous path between a mouthpiece, having an input orifice between about one to about one-and-one-half inches in diameter, and an exit port. The air column is housed within a body having a length. The ratio of length of the air column to the instrument body length is preferably greater than 1.5 to provide a compact instrument. The instrument may be manufactured tuned to a traditional key-scale note, and may include tone holes to play other fundamental notes. In certain embodiments, a vibrating membrane may be provided in sealed relation over one or more through-holes in the body to produce other sounds of which a traditional didjeridoo is incapable.

The reed plate has a plurality of reed slots formed therein and is adapted to receive the reeds of the reed comb into corresponding slots formed in the reed plate. A stepped portion formed in the reed plate is adapted to receive a reed of the reed comb therein to permit substantial encasement of the reed within the reed slot. A key benefit of this arrangement is to resist leakage of air between the reed plate and the flanks of the reed during harmonica play. The reed plate can also include a first stepped portion upon which the roots of the reeds are positioned and a second stepped portion positioned adjacent to the tips of the reeds. Other structures are disclosed that include a radiused surface formed on a portion of the reed or on the surface of the reed slot in which the reed is positioned.

Abstract: Vertical mouthpiece motion replaces the traditional chromatic harmonica's slide valve function and eliminates the valve as a source of air leakage, friction, and sticking. Because the player's mouth pushes a movable mouthpiece between an upper and a lower position with respect to the attached chromatic harmonica, the use of the player's hands is unnecessary. In the upper position, the row of air holes conducts the player's breath through an upper row of reed chambers. In the lower position, the same air holes conduct the player's breath through a lower row of reed chambers.

Abstract: An improved comb for a harmonica including one or more check valves mounted within the comb for improving performance and tonality and simplifying construction. The use of check valves mounted over valve slots has been previously disclosed as a method of increasing the musical range and volume of the instrument. This invention incorporates check valves but locates them within the comb of the harmonica. By placing all the check valves within the comb, construction of the harmonica is greatly simplified, air loss between various components is greatly decreased, and check valves are removed from close proximity with reeds thereby decreasing interference with the reeds, increasing volume and performance, and increasing the resonance of overtones.
