摘要： Disclosed is a novel "cajon" or box percussion instrument. A cuboid or rectangular shaped percussion instrument has six sides. It usually consists of five (5) panels of equal thickness with at least one panel of a thinner more flexible sixth panel which vibrates when percussed. One or more chambers and interior porting system are included in improve tonal quality. One or more external port openings, usually rectangular in shape, are formed in the unit to permit sound to emanate. Different external port geometries including shapes and sizes are contemplated. Encompassed in a single unit, the chamber delivers distinct independent tones. In some models, an interior resonating baffle and reflective block have been introduced to direct sound waves and air flow out of the exterior port opening creating a greater larger frequency range and greater amplification. In one example multiple independent chambers and interior porting system are included to improve the tonal quality.
