Embodiment 1

[0046] The crossbar 13 is pre-implanted into the monoblock 14; use the fixing piece 8 to pass through the positioning hole 6 of the bottom plate 3 from bottom to top, and enter the fixing hole 7 at the bottom of the monoblock 14 to complete the connection between each monoblock 14 and the bottom plate 3; The single block 14 has two specifications, high and short. The short single block is in the front row, and the lower key 2 is installed, and the high single block is in the back row, and the upper layer key 2 is installed; In the groove 24, use the mounting screw 5 to pass through the mounting hole 4 of the bottom plate 3, and implant it into the resonator 1 to complete the connection between the bottom plate 3 with the single piece 14 and the resonator 1; The position above the cross bar 13 passes through the large through hole 11, aligns the playing end, the adjustment part 10 touches the key 2 through the adjustment hole 9, uses a tuner to check the sound of each key 2, and...

Embodiment 2

[0048] The installation method is the same as that of Embodiment 1, the difference is that the monolith 14 does not have an implanted cross bar 13, such as Figure 4 shown.

Embodiment 3

[0050] Use the fixing part 8 to pass through the positioning hole 6 of the bottom plate 3 and the integral support 16 from bottom to top, enter the fixing hole 7 at the bottom of the column 15, and complete the connection of each column 15, the integral support 16 and the bottom plate 3; the column 15, the integrated The support members 16 have two specifications, high and short. The short ones are in the front row, and the lower keys 2 are installed, and the tall ones are in the back row, and the upper layer keys 2 are installed; In the groove 24, use the mounting screw 5 to pass through the mounting hole 4 of the bottom plate 3, and implant it into the resonator 1 to complete the connection with the resonator 1; pass the keys 2 through the large through hole 11 in turn, without going beyond the notch 17, Align the playing end, and the adjustment part 10 touches the key 2 through the adjustment hole 9; use a tuner to check the sound of each key 2, and use corresponding tools t...

Abstract

The invention discloses an mbira with independently-installed adjustable double-layer keys. An independent supporting mechanism and an independent fixing mechanism are used, so that each key can be independently installed and adjusted; keys of one specification can be used, and keys of various specifications can also be used, so that the keys are more convenient to manufacture, install and replace; for the arrangement of various musical scales, the key playing ends can be aligned, and the hand feeling is more comfortable; noise and mute can be solved by adjusting the tensity of the keys.
