This patent specification relates to the field of percussion instruments and devices. More specifically, this patent specification relates to a stomp box percussion device that is able to produce a variety of sounds, which is portable in nature, and able to easily interface into a performance space.
It is common for a solo artist or small performing group or band to desire to add the rhythmical sound of a bass drum to their musical performance while playing an instrument such as a guitar or keyboard. Often these musicians will incorporate a stomp box into their performance. A stomp box or stompbox is a simple percussion instrument consisting of a box placed under the foot, which is tapped or stamped on rhythmically to produce a sound similar to that of a bass drum. A stomp box allows a performer such as a singer or guitar player to create a simple rhythmic self-accompaniment. Unfortunately, currently available stomp boxes often do not produce the deep frequency sound of a bass drum that is desired by the performer. These stomp boxes also are unable to provide a surface which allows for a natural motion of generating the sound without hindering the playing of the performer's main instrument.
Therefore, a need exists for novel stomp box percussion devices. There is also a need for novel stomp box percussion devices which are able to provide a percussion device that can be easily implemented by a performer. A further need exists for novel stomp box percussion devices which are able to produce desired bass drum sounds in addition to other percussion embellishment sounds. Finally, a need exists for novel stomp box percussion devices that are portable in nature and able to easily interface into the performance space of a musician.
A stomp box percussion device is provided which preferably may be called the Sole Stomp Box. The device is configured to closely match the low frequency sound of an actual bass drum, and is designed to allow the musician to comfortably stand with both feet on the device in a natural performance position, and while stomping with one foot, eliminate the natural dampening of the stationary foot that remains planted on the top of the device. Preferably, the device may be configured to offer a sizeable and stable platform designed to allow the musician to stand and move comfortably on the device in accordance with their normal live performance, and may be configured to allow for the musician's natural and normal rhythmical action of either or both feet without undue strain thereby enabling the device to be played for long periods of time. Additionally, the device is simple, easily transportable, and easily implemented into the venue set-up to provide a high quality non-prerecorded bass drum sound (along with other percussion embellishment sounds) into the musician's live performance.
In some embodiments, the stomp box percussion device may include a top plate having an exterior surface and an opposing interior surface. One or more sidewalls may be coupled to the interior surface, and a chamber may be formed by the interior surface and the one or more sidewalls. Preferably, a sound device may be disposed in the chamber. A central kerf may be disposed on the exterior surface of the top plate, and one or more alternating kerfs may be disposed on the interior surface of the top plate.
In further embodiments, the device may comprise a frame having a top plate, a bottom plate, and one or more sidewalls, which may connect the top plate and bottom plate. The frame may bound and form a generally rectangular prism shaped chamber. A sound device may be disposed in the chamber, and optionally a central aperture may pass through a sidewall of the frame to facilitate the communication of sound out of the chamber. Optionally, the sound device may be in communication with an audio connector. A central kerf may be centrally disposed on the exterior surface of the top plate, and optionally one or more alternating kerfs may be disposed on the interior surface of the top plate. The top plate may support the weight of a performer, while the performer's alternating or inactive (supporting) foot may not dampen the resonance of the top plate when he/she is standing on and playing the device with their active (stomping or tapping) foot.
In further preferred embodiments, the device provides a solid platform of a standard shape for a musician to stand on in a comfortable, natural position with both feet on the top plate and stomp or tap either foot to generate a bass or kick drum sound. The device is basically a stage on a stage for the performer. The top plate may comprise a central kerf that prevents the alternating or inactive (supporting) foot of the musician from dampening the effect of the stomping foot. Alternating kerfs, optionally positioned randomly, on the underside of the top plate further increase resonance, while a central aperture in the frame matches the frequency of the top plate with the air in the chamber, causing the air in the central aperture to act like a mass, and the air in the chamber will act like a spring, producing a louder and deeper sound.

The frame 11 may bound and form a generally rectangular prism shaped chamber 18. A sound device 19 may be disposed in the chamber 18, and a central aperture 21 may pass through a sidewall 14, 15, 16, 17, of the frame 11 to facilitate the communication of sound out of the chamber 18. The sound device 19 may be in communication with an audio connector 22. A central kerf 23 may be centrally disposed on the top plate 12, and one or more alternating kerfs 25 may be disposed on the interior surface 26 of the top plate 12. The top plate 12 may support the weight of a performer, while the performer's alternating or inactive (supporting) foot may not dampen the resonance of the top plate 12 when he/she is standing on and playing the device 100 with their active (stomping or tapping) foot.
In some embodiments, a frame 11 may be formed by one or more, such as four, generally rectangular shaped sidewalls 14, 15, 16, 17, a generally square shaped top plate 12, and a generally square shaped bottom plate 13. The top plate 12 and bottom plate 13 may be generally parallel and opposingly positioned to each other, and the top plate 12 and bottom plate 13 may each be coupled, approximately perpendicularly, to the sidewalls 14, 15, 16, 17. Each sidewall 14, 15, 16, 17, may be approximately coupled perpendicularly to two other sidewalls 14, 15, 16, 17, to preferably form a generally rectangular prism shaped container which may define a generally rectangular prism shaped chamber 18. In other embodiments, the sidewalls 14, 15, 16, 17, a top plate 12, a bottom plate 13, or any other element of the device 100 disclosed herein may be configured in a plurality of sizes and shapes including “T” shaped, “X” shaped, square shaped, rectangular shaped, cylinder shaped, cuboid shaped, hexagonal prism shaped, triangular prism shaped, or any other geometric or non-geometric shape, including combinations of shapes. It is not intended herein to mention all the possible alternatives, equivalent forms or ramifications of the invention. It is understood that the terms and proposed shapes used herein are merely descriptive, rather than limiting, and that various changes, such as to size and shape, may be made without departing from the spirit or scope of the invention. For example, the device 100 may comprise a generally circular shaped top plate 12, optionally a generally circular shaped bottom plate 13, and an annular shaped first sidewall 13 that may be coupled together to form a generally cylindrical shaped chamber 18. As another example, the device 100 may comprise a generally triangular shaped top plate 12, optionally a generally triangular shaped bottom plate 13, and three sidewalls 13, 14, 15, that may be coupled together to form a generally triangular prism shaped chamber 18.
In some embodiments, the frame 11 may comprise four similarly dimensioned sidewalls 14, 15, 16, 17. In preferred embodiments, each sidewall 14, 15, 16, 17, may be approximately 3.5 inches wide and approximately 0.75 inches thick. In other embodiments, one or more sidewalls 14, 15, 16, 17, may be configured with any other dimensions which enable the sidewalls 14, 15, 16, 17, to provide structural support of the top plate 12 as well as influencing the volume of the device 100. In further embodiments, one or more sidewalls 14, 15, 16, 17, may be made from or comprise a wood material, such as solid poplar, maple, and/or any other choice of hardwood(s).

In further preferred embodiments, the device 100 may include four sidewalls 14, 15, 16, 17, arranged into a square shape. The sidewalls 14, 15, 16, 17, may comprise one or more splines which may be used to join and couple the sidewalls 14, 15, 16, 17, together with an adhesive; although any other coupling method may be used.
The device 100 may include a bottom plate 13 which may be coupled to the lower portions of the sidewalls 14, 15, 16, 17. In preferred embodiments, the sidewalls 14, 15, 16, 17, may each be routed approximately 0.5 of an inch on the bottom edge of their respective inside faces so a generally rectangular planar shaped bottom plate 13 may be inset to complete the enclosure of the chamber 18. In some embodiments, the bottom plate 13 may be approximately 0.186 inches thick. It is noted a relatively thicker bottom plate 13, such as approximately 0.25 inches may be used, but a thicker bottom plate 13 will change the way that the device 100 resonates. A bottom plate 13 may be attached to the sidewalls 14, 15, 16, 17, with adhesive, fasteners, or any other suitable coupling method. Preferably, a bottom plate 13 may be generally planar in shape having a generally planar in shape bottom interior surface 33 and a generally planar in shape bottom exterior surface 34.
In preferred embodiments, the bottom plate 13 may be made from or comprise a different material than which is used to form all or portions of the sidewalls 14, 15, 16, 17, and top plate 12, such as a lauan plywood (also known as Philippine mahogany). Lauan plywood is preferable for the bottom plate 13 as it resonates at a lower frequency than birch plywood, producing a more resonant low and enhancing the tone of the sound.
