As the saying: "The plate kalimba is more pronounced than the box kalimba, but the volume is much smaller than the box kalimba",HLURU engineers embedded the plate kalimba design on a resonating cabinet to get more volume and retain the rich tone of the plate kalimba, which was patented in the US(Patent No.: US D940230 S) and The EU(Patent No.: 008311799-0007).Meanwhile, hluru engineers have made three round holes in the left and right sides of the resonator box, which can produce a wonderful and magical "WA" sound when played by palm control.
