Abstract: Tunable cajón devices, including tuning and adjustment during a performance, are disclosed. In an aspect, the present disclosure provides a tunable cajón device wherein internal strings or cords under tension may be tuned via the manual manipulation of tuners accessible via a top surface of the cajón. As such, a cajón player may view tuner position and adjust the tuner from the traditional playing position. Adjustments (i.e., tuning of internal strings) may be done before, during, or after a performance.

Abstract: A percussive shaker instrument with improved control in producing rhythmic sound and capable of producing different percussive sounds in a single shaker is disclosed. The shaker comprises one or more channels filled with a striker material. The channel isolates the striker material from the striker material in other channels and from any other part of the shaker. The striker material is freely movable within the channel such that it may collide with a striking surface when the shaker is moved.

Abstract: Systems, methods, and apparatuses that allow for a high-hat mounted tambourine musical instrument to be muted are disclosed. In an aspect, the present disclosure provides a mutable tambourine jingle assembly that can be permanently engaged with the press of a button or otherwise. As such, the need for a user to physically hold the tambourine or an attached lever (e.g., a foot pedal) to mute the jingle assembly is obviated. In another aspect of the present disclosure, apparatuses are provided that facilitate a user simultaneously muting all of the jingles of a hi-hat mounted tambourine.

Abstract: A hand-held percussive shaker assembly comprising two identical shakers capable of producing different percussive sounds and rhythms in a single assembly is disclosed. The shakers are detachably connected by an integrally formed lock assembly. The shakers may be played as a single assembly or detached and played individually. Each shaker comprises one or more bottles filled with a striker material. Each bottle isolates its striker material from the striker material in other bottles and from any other part of the shaker. The shakers may produce the same or different tones when the shaker assembly is moved.

Abstract: Disclosed is a tuning system for tuning a hand percussion instrument having a head and a shell. The tuning system comprises a rim, the rim secured to the head of the instrument, the rim comprising at least one receptacle, the receptacle positioned at outer periphery of the rim such that the receptacle body is below the plane of the rim, a side plate assembly, the side plate assembly secured to the shell of the instrument, a tuning rod, the tuning rod having a first end secured to the receptacle for varying the tension on the head, and the tuning rod having a second end secured to the side plate assembly.

Abstract: An adjustable, spring-activated wing nut-less cymbal mount having a rotating stop arm that may be quickly opened and closed for easy mounting and dismounting of a cymbal and cymbal felts. The device is hand operated without tools and can be adjusted for cymbal play action, as well to better adapt to different weight cymbals. The device is self-contained to avoid misplacing parts during cymbal changeovers.

Abstract: An audio sound system has a printed circuit board disposed within a compact case. The PCB has a power conversion circuit for generating an operating potential, audio amplifier circuit coupled for receiving the operating potential to amplify an audio signal, and peak voltage and current limiting circuit coupled to the audio amplifier circuit to avoid hard clipping of the audio signal. The power conversion circuit has heat-generating components. A cooling tunnel is mounted over the printed circuit board. A cooling fan is mounted in the compact case adjacent a first opening of the cooling tunnel for directing air flow through a second opening of the cooling tunnel over the PCB. The cooling tunnel has a notch formed in a side of the cooling tunnel for directing air flow over the PCB. The audio amplifier circuit can generate greater than 500 watts into a 4-ohm load.

Abstract: A triangle musical instrument that may be played using a single hand. The triangle is formed such that a percussionist is able to grasp the triangle in one hand and shake it in a back-and-forth motion to produce the familiar triangle musical instrument sound. Openings formed in the sides of the instrument allow the percussionist to mute the sounds.

Abstract: An assembly for mounting musical instruments comprises a base, a bearing, the bearing secured to the base, a post, the post comprising a head, the head comprising a plurality of mounting flanges for mounting a musical instrument, and a body, the body fixedly connected to head at a first end, the body further rotatably engaged to the bearing at a second end.
