摘要： A percussion instrument includes a drum head arranged on a support with a flange of the drum head extending from the support, wherein the support is an inner ring, and an outer ring comprising an abutment that is configured to engage the flange of the drum head. The inner ring and the outer ring are concentrically arranged and moveable relative to each other in a longitudinal direction. The percussion instrument also includes a tensioning mechanism having an external screw thread going around on an outer circumference of the inner ring, and an internal screw thread going around on an inner circumference of the outer ring.

摘要： A reduced volume drumhead has a layer of porous material and a ring of compressible material. The ring of compressible material is fixed to the underside of the layer of porous material in a substantially centered or coaxial position with the porous material stretched across a hoop in tension. The ring may be formed of a foam or similar material with compressibility and stretchability under tension and defines an open central area of the drumhead for striking. The ring may be formed of segments and thus include one or more circumferential breaks with spacing. The drumhead provides natural tonal characteristics and has a natural feel when struck.

摘要： A snare drum including a self-alignment component is disclosed. The self-alignment component may be engaged by a tensioning band, which can attach to one end of a snare that contacts or is proximate a bottom drum head. The tensioning band may loop around a part of the self-alignment component, such as an alignment piece thereof. The geometry of the self-alignment component is designed to allow the tensioning band to self-align such that portions on opposing sides of the alignment piece have approximately equal tension therein and/or have approximately equal length, thus allowing for a properly aligned snare on the bottom drum head. The self-alignment component can include a plate portion attached to a drum sidewall or tensioning device on a drum sidewall, and can further include a cover portion for attachment to the plate portion.

摘要： An enhanced collapsible drum provides for a collapsible and expandable drum that in its collapsed state provides for improved portability and storage, while in its expanded state maintains the look, feel and playing quality of a drum having a traditional unibody shell or base design. The collapsible drum may be comprised of an elongated base or shell portion divided into two or more sections which may be nested in the collapsed position and can be extended and locked together by mating interlocking components to form an elongated drum base or shell in the expanded position. The collapsible drum may additionally include an internal lighting device and control responsive to sound. The collapsible drum may also include a case, handles and a strap for carrying or supporting the drum while playing or for securing the drum sections in the closed position.

摘要： A snare drum with a snare bed created by a continuous curve in the lower edge of the snare drum shell is disclosed. The continuous curve has two maxima and two minima. The continuous curve is cut into the snare drum shell blank, from which the snare drum shell is bent. The continuous curve can be sinusoidal, polynomial, or spline. The two minima are disposed opposite one another when the shell is formed. The snare bed thus created provides superior tuning, reduced buzzing, and improved sensitivity.

摘要： Two or more deadening elements are in contact with the underside of the drum head and are provided with a mechanism which moves the deadener or deadeners across the drum head thus varying the effective resonating area of the head so that the drum can be tuned while playing. As an example, the drum tuning can be changed from a bass drum to a concert tom. The preferred embodiment includes a pair of opposed, curved deadeners which are moved towards and away from one another in concentric relationship with the drum head. The actuator system is arranged to move the first deadening element at a rate of movement different from the second and thus defining three effective resonating areas of different sizes between the first and the periphery, between the first and the second and between the second and the periphery.

摘要： A tuning assembly and tunable drug system are described. The tuning assembly including a pressure ring, a rope ring with a first plurality of holes and a second plurality of holes, a rope system coupled to the first plurality of holes and a membrane of a drum head, and a plurality of fasteners engaging the second plurality of holes in the rope ring and a surface of the pressure ring. Tightening the plurality of fasteners increases the distance between the rope ring and the pressure ring causing the rope ring to pull the rope system and apply pressure to the membrane of the drum head.

摘要： A cable and pulley or guide apparatus for accurately tuning and securing a tunable vibrating membrane on a cylindrical shell by means of a plurality of either fixed-angle pulley or guide assemblies not parallel to the top-bottom axis of the shell, or adjustable-angle pulley or guide assemblies not parallel to the top-bottom axis of the shell, built into or attached to purpose built hoops, attached to hoops with protruding flanges through holes or slots, or attached to a claw or hook apparatus which secures over the edge of annular hoops, through which a cable is laced and fed into the tensioning mechanism(s) to increase or decrease the tension on the cable, thus tensioning the vibrating membrane or heads against the shell, the angles of the pulley or guide assemblies adjustable to conform to the natural angle of the cable traversing the circumference of the shell.

摘要： According to some embodiments, a low volume drumhead is disclosed. The low volume drumhead comprises a mesh layer to be removably coupled to a drum hoop. The low volume drumhead further comprises a non-mesh layer affixed to a beatable surface of the mesh layer. An adhesive comprising elastic polymers is used to couple the mesh layer to the non-mesh layer.

摘要： A drum and pitch adjustment device for a drum includes a drum with a sound producing membrane, a device for applying pressure to the sound producing membrane, and a cable configured to the device for applying and releasing pressure to the sound producing membrane, changing the pitch of the drum, but goes back to the drum's original pitch when absent this force. A hand operated lever, located on the side of the drum, operates the cable which makes the pressure device push up against the sound producing membrane and changing it's pitch. Absent this force, the drum goes back to its original pitch, which creates different tonal variety when played in real-time.
