摘要: A drum with an adjustable depth is described. The drum includes a top head, a bottom head, and a shell. The shell is constructed such that the bottom head can be moved away from the top head, creating a drum with a different depth. The shell comprises an inner and outer shell. A handle can be turned, turning a drive sleeve in the interior of the drum. The drive sleeve translates the rotational motion into a vertical motion, changing the distance between the top and bottom heads. There may be an additional drive sleeve directly across from the initial drive sleeve, coupled via a drive shaft, to force the drum heads to move apart from each other in a substantially parallel manner. In a similar manner additional drive sleeves may be present to better keep the heads parallel.
