摘要： 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.

摘要： A snare drum attachment is disclosed. A mounted body is mounted to the snare drum and houses a first magnet. A moveable body is coupled to the mounted body. The moveable body is configured to retain tensioned snares a set distance from a snare head of the snare drum. The moveable body houses a second magnet magnetically coupled to the first magnet so as to generate a magnetic force. A manual actuator is coupled to the first magnet. Actuation of the manual actuator alters the magnetic force so as to displace the moveable body relative to the mounted body. The displacement changes the set distance of the tensioned snares from the snare head.

摘要： Improvements in a motorized microphone rail 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 positional with a drive screw that is powered by a motor. The microphone can be moved along the supporting rail to alter the sound based upon the phasing of the sound wave between the drum heads or the sound producing elements. Electronic drive and control for operating a motor that positions the microphone is also disclosed.

摘要： 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.

摘要： An improvement in a color guard flag pole weight is disclosed. The flag pole weight is inserted into one or both ends of a flag pole. For larger or heavier flag poles or when a performer is performing a great deal of spinning against the wind, weighting the pole dramatically improves the ease of rotation of the flag pole to counteract the drag created when the flag pole catches the wind and improves the ease of rotation for both the spinning and the tossing. When the weight is inserted into the flag pole, a split ring on the weight is expandable to grip the inside diameter of the pole. The weight of the insert is adjustable by screwing one or more weights into the insert. The additional weights are male-female threaded to allow for a large number of weights to be added and limited only to the length of the flag pole.
摘要翻译：公开了彩色防护标志杆重量的改进。旗杆重量插入旗杆的一端或两端。对于较大或较重的旗杆，或者当表演者对风进行大量旋转时，对极点进行加重可显着提高旗杆的旋转容易度，以抵抗旗杆抓住风而产生的阻力，并提高轻松的旋转和旋转。当重量插入旗杆时，重物上的开口环可扩张以夹紧杆的内径。插入件的重量可以通过将一个或多个重物拧入插入件中来调节。额外的重量是公 - 母螺纹，以允许大量的重量被添加并且仅限于标志杆的长度。

摘要： The present invention is embodied in a grill having a firebox with a front rotisserie mount assembly and a pair of heat shield assemblies. The front rotisserie mount assembly is to help mount a rotisserie on the grill along a longitudinal axis extending from the front of the grill to the rear of the grill. The front rotisserie mount assembly also acts in conjunction with a pair of heat shield assemblies in the firebox to help concentrate heat generated underneath the rotisserie.

摘要： Improvements in a drum practice pad are disclosed. The practice pad is intended for use with a mobile or shoulder mounted percussion instrument carrier or with a stand configured for use with a percussion instrument. The practice pad incorporates most or all of the geometry of a drum that is addressed by a player. This geometry includes a portion of the striking surface, and a portion of the drum rim. The sticking surface is adjustable within the portion of the drum rim to match the central playing area and the height of the playing surface to the rim of the drum. The assembly allows for attachment or mounting and use of a practice pad from a third party. The strike location of the practice pad is adjustable to simulate different diameter drums. The incorporation of the drum rim allows players to practice rim shots.

摘要： The present invention is embodied in a grill configured for quick assembly, a method of partially pre-assembling the grill for shipping from the factory in a container, and a method of assembling the grill when removed from the shipping container. The grill comprises a firebox assembly for mounting on a cart assembly, the cart assembly having first and second support assemblies and at least one linking member interconnecting them. A hinge or pivot in the mid-portion of the linking member divides it into first and second linking member portions, and the opposite ends of the linking member portions are pivotally connected by hinges or the like to the first and second support assemblies. The linking member holds the first and second support assemblies together in a partially pre-assembled state, and the pivotal connections of the linking member portions allow the two assemblies to be folded for packaging in a shipping container. When removed from the container, the pivotal connections of the linking member portions allow the first and second support assemblies to be unfolded, with the linking member holding the two support assemblies in approximately the proper position with respect to each other and to the firebox assembly for assembly of the grill, thus allowing for easier and quicker grill assembly by one person.
摘要翻译：本发明体现在一种构造成用于快速组装的格栅中，一种部分地预先组装用于从容器运输的格栅的方法，以及当从运输容器移除时组装格栅的方法。该格栅包括用于安装在手推车组件上的火箱组件，所述手推车组件具有第一和第二支撑组件以及将它们互连的至少一个连接构件。在连接构件的中间部分的铰链或枢轴将其分成第一和第二连接构件部分，并且连接构件部分的相对端部通过铰链等枢转地连接到第一和第二支撑组件。连接构件将第一和第二支撑组件以部分预组装状态保持在一起，并且连接构件部分的枢转连接允许两个组件折叠以便包装在运输容器中。当从容器移除时，连接构件部分的枢转连接允许第一和第二支撑组件展开，其中连接构件将两个支撑组件保持在相对于彼此大致适当的位置并且与火箱组件接合组装格栅，从而允许一个人更容易和更快速地组装格栅。
