Seven-sound box-type drum

Abstract

The invention relates to a percussion instrument, in particular to a box-type drum which can produce seven different sounds. The drum body of the seven-sound box-type drum is an injection-molded integral box-type plastic drum body. Seven drum tubes from small to large are clamped from left to right between the front and back sides of the upper part of the drum body. A summation tone drum box is arranged in the middle of the drum body. The drum body has seven sound holes from small to large in the front side. A drum base is buckled at the bottom of the drum body. The upper and lower ends of the seven drum tubes are respectively covered with the equal-diameter seven drumheads from small to large. When the drumheads from large to small of the seven-sound box-type drum manufactured through the technical scheme are hit, seven obviously different sounds from low to high are produced. The large-diameter drumheads produce low-frequency, vigorous and powerful sounds. The medium-diameter drumheads produce medium-frequency, round and rich sounds. The small-diameter drumheads produce high-frequency, clean and transparent sounds. As the summation tone drum box is arranged in the middle of the drum body, the sound of the drum corresponds to the sound in the summation tone drum box, and the music tone is harmonious.

Description

technical field [0001] The invention relates to a percussion instrument, in particular to a cajon drum capable of emitting seven different drum sounds. Background technique [0002] The drum is generally covered with a taut tympanic membrane on one or both sides of the cylindrical drum body; the drum can be struck by hand or a drum stick; the drum currently in use generally has one or two tympanic membranes of equal diameter, So the drum can only emit the drum audio that is inherent to the eardrum. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a seven-speaker drum capable of emitting seven different drum sounds. [0004] The technical solution adopted by the present invention is: a seven-speaker drum, which includes a cylindrical drum and a tympanum, and is characterized in that: the drum body of the seven-speaker drum is an integral box-type plastic drum body formed by injection molding; There are seven drum...
