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： Described herein are multipiece drum lugs and drum lug assemblies for use with percussion instruments such as drums. The drum lugs can include a separate base and a separate cap that can be interlocked, along with an insert to prevent rotation and disconnection. Receivers can be placed in the lug prior to the connection of the base and cap and sandwiched therebetween. Such a lug assembly can enable the use of regular size tension rods on drums having a relatively small depth.

摘要： It is made possible to give prevailing torque to an adjustment bolt in a simple manner without troublesome adjustment work. An anti-loosening adjustment bolt assembly includes: a cylindrical pipe (6) adapted to be fitted on the screw shaft (2a) of the adjustment bolt (2); and a nut (7) having a threaded hole for allowing the screw shaft (2a) to be threadably mounted thereon; the bottom of the nut (7) includes a recess (7a) adapted to allow the upper end of the cylindrical pipe (6) to be fitted therein; the inner peripheral surface of the recess (7a) is a taper surface decreasing in diameter toward the interior; and the axis of the taper surface is slightly eccentric from the axis of the threaded hole such that, when the nut (7), threadably secured to the screw shaft (2a), is screwed toward the cylindrical pipe (6), a circumferential portion of the eccentric taper surface comes into pressure-contact with the upper end of the cylindrical pipe (6) and the axis (Q) of the threaded hole of the nut (7) is eccentric and/or inclined from the axis (0) of the screw shaft (2a) to generate prevailing torque depending on the amount of tightening of the nut (7) on the adjustment bolt (2).

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： The present invention is a system and methods for automating the tuning process for drums. The invention automatically applies tension across the batter heads of a drum. The invention consists of a plurality of electrical stepper motors each of which is connected to a gear reduction assembly and a rotating tension rod. The invention acts to exert a tensioning force on each attachment point around the circumference of the hoop(s) securing the batter head to the drum shell. An algorithm drives a microprocessor that monitors the current being used by each stepper motor assembly which is translated to torque. When the torque for each stepper motor assembly reaches a predetermined level, the tension holding the batter head and to the shell of the drum will be in tune.

摘要： A tuning system enabled to be installed inside a drum percussion musical instrument is provided comprising a cylindrical drum shell having a batter head at a top, a bottom, and one or more internal tuning assemblies (ITAs) installed within an inner volume of the drum shell. Sound elements created by striking the batter head of the drum includes any one or more of pitch, resonance and amplitude and are altered, thereby providing tuning of the drum via manipulation of the one or more of the ITAs.

摘要： A drum key includes a shank portion and defines a top hole for receiving an elongate rod, such as a drumstick. A distal end of the shank includes a socket engageable with a tension rod in a drum. A drumstick is insertable through the hole of the drum key to form a torquing wrench in situ. When formed, the drumstick forms a cross member that is used to apply a torquing force about the axis defined by the shank. Once used, the drumstick can be removed, yielding a low profile drum key that is portable.
