Abstract: A drum has a drum shell, a top head, a bottom head and a decorating piece. The drum shell has an outer surface, a top edge, a bottom edge and an annular recess. The top head is mounted at the top edge of the drum shell and the bottom head is mounted at the bottom edge of the drum shell. The annular recess is formed on the outer surface of the drum shell. The decorating piece is glued or screwed in the annular recess and is made of a material different from that of the drum shell. The decorating piece fits in the annular recess. Therefore, the drum shell with the decorating piece is a complex material structure, so the drum changes various resonance and artistic effects.

Abstract: An adjusting assembly for a drum support includes multiple adjusting holes defined through the second extension of the secondary base and multiple fixing holes defined in the first extension of the primary base. One adjusting hole corresponds to and aligns with at least two fixing holes such that relative position of the second extension to the first extension is easily adjusted and secured via fixing bolts. An urging plate received in the seat and pushed by distal free ends of two threaded bolts is able to secure the hook inside the seat to provide a supporting force to the drum.

Abstract: A key assembly for a saxophone includes an elongated body adapted to be pivotal relative to a saxophone body and having a key formed on one end of the elongated body for selectively closing a hole in the saxophone body in response to the pivotal movement of the elongated body, a casing formed on the other end of the elongated body, a sliding block movably received in the casing from the top opening of the casing and having multiple positioning holes defined in a side face thereof, a key finger button to move simultaneously with the sliding block and a locking block threadingly extendable into the casing and having a locking pin to be extendable into one of the positioning holes of the sliding block so as to secure position of the sliding block as well as the key finger button relative to the elongated body.

Abstract: A snare-adjusting device is mounted on a snare drum for adjusting tension of a snare and has a base, adjustment assembly and snare mount. The adjustment assembly is mounted through the base and has a barrel, shaft, slider, adjustment head and friction ring. The barrel has two ends. The shaft is mounted rotatably through the barrel. The slider is mounted slidably in and engages one end of the barrel and is mounted on the shaft using threads. The adjustment head is mounted securely on the shaft. The friction ring is mounted slidably through an other end of the barrel, is pressed by a resilient device to abut the adjustment head and provide friction against rotation of the adjustment head. The snare mount is attached to the slider and connects to the snare. The friction holds the adjustment head securely to maintain a steady timbre.

Abstract: A suspension device can be used to support a musical instrument for display. The suspension device has a holder and a mounting portion. The holder may be a clamp, is able to clamp and hold a musical instrument in position. The mounting portion has a stationary hook and a movable hook. The movable hook is connected with a resilient element that provides a force to pull the movable hook to move toward the stationary hook and therefor engages stably two support bars or support members at any intervals.

Abstract: A foldable guitar holder has a stationary shaft, a central shaft assembly and two symmetrical brackets. The stationary shaft has an upper end and a lower end. The central shaft has a central shaft and two assistant shafts. The central shaft has a standing portion and a longitudinal hole receiving the lower end of the stationary shaft. The assistant shafts connect pivotally to the central shaft and have two standing ends. The brackets have two supporting shafts and two holding brackets. Each supporting shaft connects pivotally to the lower end of the stationary shaft and one of the assistant shafts and has a standing part. Each holding bracket connects pivotally to the upper end of the stationary bracket. The standing portion, standing ends and standing parts allow the guitar bracket to stand on the ground steadily.

Abstract: A portable trumpet stand has an instrument bracket, multiple legs and a central post. The instrument bracket has a central hole, a top and a bottom. The legs are mounted pivotally around and protrude out radially from the instrument bracket, and each leg has a proximal end pivotally mounted in the instrument bracket. The central post is mounted slidably in the central hole of the instrument bracket, has a top end, a bottom end and a spherical cushion. The bottom end can be secured in the central hole so the central post protrudes perpendicularly up to be mounted in a cylindrical metal tube of a trumpet to hold the trumpet in position. The portable trumpet stand can be collapsed and stored in the cylindrical metal tube of a trumpet so the portable trumpet stand and the trumpet can be stored in a case altogether.

Abstract: A snare drum strainer includes a switch stand, a brake part, a suspender steady base and a pull handle driven part. The brake part can slide inside the switch stand and also can move upward and downward. The suspender steady base is steady located at a lower end of the brake part for clipping multiple snares. The pull handle driven part is pivotally coupled to the switch stand for controlling the brake part to be ascending and descending. The brake part makes use of a self-lubricating bearing and a shaft sleeve to generate a self-lubricating effect. Further, the pull handle driven part makes use of a bolt and a spacer to have the pull handle, the driven buttons and the driven pole pivotal coupled together. When the suspender steady base is in use, friction can be reduced, so as to enhance the fluid movement and further reduce the noise.
