Description

A four-legged foldable electronic drum stand

technical field

The invention relates to an electronic musical instrument stand, in particular to a four-leg foldable electronic drum stand.

Background technique

As a percussion instrument, electronic drums are suitable for various scenes. Most of the electronic drum stands on the market are four-legged drum stands that cannot be folded but are relatively stable, and three-legged foldable electronic drum stands that can be folded but are less stable. , for electronic drum racks with the same height, the drum rack size can be compared from the aspect ratio of the drum rack footprint, the larger the drum rack, the larger the footprint, but if the larger the aspect ratio of the drum rack, the drum rack The farther the center of gravity of the frame is from the shape of the drum frame or the drum frame tubes, the more unstable the drum frame is. Relatively speaking, the smaller the aspect ratio is, that is, the closer the floor area is to a square or trapezoid, the closer the center of gravity of the drum frame is to each drum frame tube. , the more stable its center of gravity is. For the three-legged foldable electronic drum stand, after assembling the drum disc, it can be found that its center of gravity is obviously biased towards the second half, regardless of the four-legged, horizontal double-rod reinforced electronic drum stand or the four-legged, horizontal single-rod electronic drum stand The center of gravity is basically at the center of the four legs, that is, the entire drum rack occupies a trapezoidal shape, the center of gravity is on the center of the trapezoid, and all the drum parts are in or above the drum tube area supported by the four legs, while A three-legged foldable electronic drum stand, in which the hi-hats are all away from the main support rod of the drum stand, and are connected to the main support rod of the drum stand through a short crossbar through a tube buckle, and then through the cymbal buckle and the cymbal-cymbal Support rod to support, which is directly equivalent to being fixed on an arm, within the range of the main support rod area of the 3-leg support drum stand, resulting in unstable hi-hat fixation, while the two first vertical rods fix six drums accessories, while the second upright rod range only fixes one drum accessory, the center of gravity of the entire drum stand is significantly shifted towards the rear half, and the hi-hat shape supported by a single arm is far from the center of gravity of the drum stand without the support of the first upright rod, knocking The force of other drum pads is strung to the hi-hat, causing the hi-hat to generate a signal, and crosstalk occurs, which puts higher requirements on the software to solve the crosstalk. Sometimes the software cannot compensate for the crosstalk caused by this hardware defect.

As shown in Figure 1 and Figure 2, most of the traditional four-leg support, horizontal double-rod reinforced electronic drum stand or four-leg support, horizontal single-rod electronic drum stand, although they are stable and stable, they appear again during transportation after use. The problem of inconvenient to carry, the size of the entire drum stand is quite large, it is not convenient for drummers to carry and carry it during performances, which brings certain troubles to drummers; and no matter the traditional four-legged support, the horizontal double-rod reinforced electronic drum stand or the four-legged support , Horizontal single-rod electronic drum stand, because two toms are directly assembled on the same drum tube, hitting one of the drum pads will generate a larger signal to the other drum pad, and it is not easy to judge whether the software recognizes the signal. It is a signal generated by drum beating, so there will be crosstalk.
