16 holes, 64 sound double-tone orifice plate mouth organs
Technical field
The present invention relates to a kind of chromatic harmonica, particularly relate to a kind of 16 holes 64 sound double-tone orifice plate mouth organs.
Technical background
At present, the chromatic harmonica of producing on the market all adopts the single-tone orifice plate, when playing wind instruments melody, high pitch partly pronounces thin and effort, and low alto divides pronunciation blunt, does not catch up with performance speed, and gas leakage is easily given playing wind instruments and is brought a lot of inconvenience, is not suitable for playing in high-grade place.
Summary of the invention
Purpose of the present invention is exactly that a kind of 16 holes, 64 sound double-tone orifice plate mouth organs that can play out double bass, bass, middle pitch, high pitch simultaneously will be provided, and it can overcome the existing existing above defective of chromatic harmonica.The object of the present invention is achieved like this, 16 holes, 64 sound double-tone orifice plate mouth organs, comprise Qin Ge, the inflexion plate loam cake, the inflexion plate lower cover, inflexion plate, the mouthpiece plate, be provided with the inflexion plate loam cake above the Qin Ge and between the mouthpiece plate, the inflexion plate lower cover, the inflexion plate loam cake, be provided with the hole of blowing above the inflexion plate lower cover with qin lattice same holes, at the inflexion plate loam cake, be provided with inflexion plate between the inflexion plate lower cover, one end of inflexion plate is provided with presses key, the inflexion plate upper punch have between the upper and lower every square hole, with blow the same half of qin checkerwork cell of being of orifice plate, be respectively arranged with grill at the tow sides of Qin Ge, following grill; It is characterized in that: described last grill is made up of last grill ground floor, last two stacks of the grill second layer; Described grill down is by grill ground floor, following two stacks of the grill second layer are formed down; To lean on the last grill ground floor of upper cover plate to mill 16 sound holes from left to right, height is short, the right long trapezoidal hole in a left side; Thin 0.18-0.25mm is milled on the surface of 6 sound holes of the last grill second layer treble 511,512,513 that leans on the qin lattice, and thin 0.08-0.15mm is milled on the surface of 10 sound holes of middle register 514~518; To go up the grill ground floor, go up the grill second layer and rush to corresponding sound hole number, high pitch octave reed is fixed on the last grill second layer by the qin lattice, bass octave reed is fixed on the last grill ground floor by upper cover plate, behind the calibration sound hole position, grill on glue last grill ground floor, the last grill second layer being bonded together and becoming; To lean on the following grill ground floor of lower cover to mill 16 sound holes from right to left, height is long, the right short trapezoidal hole in a left side; Thin 0.18-0.25mm is milled on the surface of 6 sound holes of the following grill second layer treble 711,712,713 that leans on the qin lattice, and thin 0.08-0.15mm is milled on the surface of 10 sound holes of middle register 714~718; To descend the grill ground floor towards the corresponding sound hole number of the up and down grill second layer; High pitch octave reed is fixed on the following grill second layer by the qin lattice, bass octave reed is fixed on the following grill ground floor by lower cover, behind the calibration sound hole position, with glue grill ground floor down, the grill second layer is bonded together down, grill under becoming; On last grill, following grill, there is the reverse side of tone reed to be provided with double-deck mylar sheet, and on the mylar of nexine, adds a strata ammonia ethene particulate, and make its surface galling.
The present invention has improved the voice effect of mouth organ, can be handy when particularly playing highly difficult melody, increase volume and empathize, loud simple and honest, the bright sensitivity of high pitch of bass, arbitrarily modify tone, play easily air tight, solved employing single-tone orifice plate, problem such as high pitch partly pronounces thin and effort, and bass part pronunciation is blunt.

Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As Fig. 1, Fig. 3, Fig. 4, shown in Figure 5, design double-deck grill, every layer of sound hole thickness of slab 1.2mm, the last grill ground floor that will lean on upper cover plate mill long be 74.2mm, high trapezoidal hole for short 14 mm in a left side, right long 22mm apart from A face 4.2mm place at 1.5mm place, the 519 sound hole left side; At the last grill second layer 518 sound hole places, mill thin long 15mm, thick 0.08mm, mill thin long 14mm, thick 0.085mm at sound hole 517 places, mill thin long 12.5mm, thick 0.09mm at 516 places, mill thin long 10.9mm, thick 0.12mm at 515 places, mill thin long 9.9mm, thick 0.15mm at 514 places, mill thin long 8.2mm, thick 0.18mm at 513 places, mill thin long 7.6mm, thick 0.2mm at 512 places, mill thin long 6.9mm, thick 0.23mm at 511 places; To go up the grill ground floor rushes to and the corresponding sound hole number of the last grill second layer; High pitch octave reed is fixed on the last grill second layer by the qin lattice, bass octave reed is fixed on the last grill ground floor by upper cover plate, behind the instrument calibration sound hole position, grill on glue last grill ground floor, the last grill second layer being bonded together and becoming.As Fig. 1, Fig. 6, Fig. 7, shown in Figure 8, the following grill that will lean on lower cover mills long be 74.2mm, high trapezoidal hole for the long 22mm in a left side, right short 14 mm apart from ground floor A face 4.2mm place at 1.5mm place, the 719 sound hole right side; At the following grill second layer 718 sound hole places, mill thin long 15mm, thick 0.08mm, mill thin long 14mm, thick 0.085mm at 717 sound hole places, mill thin long 12.5mm, thick 0.09mm at 716 sound hole places, mill thin long 10.9mm, thick 0.12mm at 715 sound hole places, mill thin long 9.9mm, thick 0.15mm at 714 sound hole places, mill thin long 8.2mm, thick 0.18mm at 713 sound hole places, mill thin long 7.6mm, thick 0.2mm at 712 sound hole places, mill thin long 6.9mm, thick 0.23mm at 711 sound hole places; To descend the grill ground floor towards the corresponding sound hole number of the up and down grill second layer; High pitch octave reed is fixed on the following grill second layer by the qin lattice, bass octave reed is fixed on the following grill ground floor by lower cover, behind the instrument calibration sound hole position, with glue grill ground floor down, the grill second layer is bonded together down, grill under becoming.The reverse side that tone reed is housed on last grill, following grill is provided with double-deck mylar sheet, and on the mylar of nexine, adds a strata ammonia ethene particulate, and makes its surface galling; Mouthpiece on the mouthpiece plate adopts the suitable round mouth of depth thickness, and lines are mellow and full, comfortable taste, air tight.The present invention has improved the voice effect of mouth organ, so its bass tone color is simple and honest mellow and full, and very " allusion ", high pitch is bright sensitive, plays easily.
