Abstract: An acoustic variable porting system includes an acoustic element and an acoustic variable porting element forming a port into the acoustic element. The acoustic variable porting element is adjustable between at least an open position, in which the port is generally open, and a closed position, in which the port is generally closed. The acoustic element may be at least one of: a sub-kick, a ported drum, and a speaker.

Abstract: A percussion instrument mount includes a base that supports a percussion instrument in a playing position. The percussion instrument mount also includes a swing arm that is coupled to the percussion instrument, and is also coupled to the base via a joint such that the swing arm rotates about the joint from an equilibrium position in response to a playing impact on the percussion instrument. The percussion instrument mount still further includes a playing impact energy absorber that provides a restoring force to the swing arm so as to return the swing arm to the equilibrium position.

Abstract: Improvements in a tilting, lifting stand are presented. The tilt, lift stand is for a musical instrument stand or to elevate/tilt a speaker and or amplifier and rigidly supports a sousaphone brass type instruments, speaker or amplifier in an in a stored and in a playable or elevated position. The stand supports all or the majority of the weight of the instrument or speaker or amplifier in a static position to relieve the weight of the musical instrument or speaker or amplifier. The stand has legs that are extendable to rest on multiple levels as might be found in a stadium. The stand further has a securing mechanism that gently grasps a tubular section to hold the musical instrument. The speaker stand can be easily collapsed for transportation and storage.

Abstract: A percussion instrument holder that allows attachment to a user mounted carrier. The holder allows adjustment for positioning about the user, and pivoting of the holder to allow the holder to pivot or rotate up to allow the holder with instruments to fit a narrower space. The holder further allows for pivotal attachment of individual drums to link or pivot allowing the linked drums to articulate. The holder can also consist of members that allow a connected drum to move in horizontal position, angle, or height of the drum. A plurality of unique drum connecting members is disclosed that allow the connecting members to connect onto drum tension rods or on a drum lug. The plurality of connecting members can be fabricated from multiple pieces that can interconnectably be locked into position.

Abstract: A musical instrument stand has an expandable telescoping stand with an adjustable travel stop included interior to an extension tube diameter. The telescopic extension of the musical instrument stand is adjustable by repositioning the travel stop longitudinally within the tube.

Abstract: A marching drum articulation dampener for percussion instrument holder that allows attachment to a user mounted carrier. The holder allows adjustment for positioning about the user, and pivoting of the holder to allow the holder to pivot or rotate up to allow the holder with instruments to fit a narrower space. The holder further allows the pivotal attachment of individual drums to link or pivot allowing the linked drums to articulate. The holder can also consist of members that allow a connected drum to move in horizontal position, angle, or height of the drum. A plurality of unique drum connecting members is disclosed that allow the connecting members to connect onto drum tension rods or on a drum lug. A lift assisting mechanism is used to assist in lifts drums from a horizontal to a vertical orientation.

Abstract: Improvements in an expandable stand with an adjustable travel stop within a musical instrument stand or elevating speaker is presented. The stand supports some weight of the instrument or speaker to relieve the weight. The stand has a securing mechanism that grasps a tubular section to hold the musical instrument. The stand is collapsible to fit within or can be carried with the case for the instrument. The speaker stand can be easily collapsed for transportation and storage. An adjustable travel stop for the travel stop to be inserted and removed from the inner tube diameter. The ability to insert and remove the travel stop allows the extension or the travel of the lift to be adjustable by moving the travel stop within the tube. The travel stop can be used to stop the travel length and or to establish the starting point for expansion.

Abstract: A shoulder supported carrier structure supports percussion instruments on shoulder shoulders of a user is disclosed. A connecting member that spans between the shoulder supporting member behind the user or performer. The connecting member is joined to an arm that is connected to at a back member that allows the back member to pivot and translate relative to the two shoulder supporting members to allow the back member to align with a back of a user. The connecting member may be joined to the one arm with a frictional connection. The arm may be connected to the back member with a frictional connection. The back member at least partially contours to the shape of the back and may further include an inflatable cushioning bladder and is positioned between and under shoulder blades of the user to increase arm mobility.

Abstract: An instrument carrier is disclosed for supporting one or more drums without using traditional “J” rods components. The carrier uses sliders that eliminate the interference with the user's legs and more particularly the user's thighs and provides a more natural stride of the user. The drum mounting structure is repositioned or translated on the sliders. The carrier allows the drum to be rigidly mounted in a variety of positions relative to the user. The cantilevered weight of the drum(s) rotates the drum or drum array to lock the drum(s) into a vertical or horizontal slots or saddle. In another embodiment a bridge extends from the carrier to a single post or tube to support a slidably mounted single drum. The structure also eliminates the necessity of a structurally rigid fixed abdomen plate and allows for use of a flexible and conforming abdomen plate.

Abstract: Improvements in a microphone system for a musical instrument and more particularly for a percussion instrument such as a drum, marimba or similar musical instrument. The microphone system includes a vibration isolation system. A vertical or horizontal tracking system bridges across supports of a drum or marimba in a vertical or horizontal tracking system. One or more microphones are supported on the first bridging structure. The microphone(s) are positionally secured on the horizontal tracking system. Both the microphones and the horizontal tracking system provide vibration isolation to all of the microphones. A cable managements system is also disclosed to reduce mechanical vibration and eliminate transmission of undesirable sounds.
