Description

24-hole 48-tone bass range full-scale harmonica

Technical Field

The invention relates to the technical field of harmonicas, in particular to a 24-hole 48-tone full scale harmonica in a bass region.

Background

Harmonica, blow or breathe in with the mouth, make the multiple reed musical instrument of metal reed vibration sound production, the instrument of playing that belongs to the free reed in the musical instrument classification belongs to the instrument of playing, because send out the sound source and be the reed that length is between 1.5 to 3.5 centimetres rather than the air column, mainly divide into solo harmonica and harmonica, have different types respectively again, its register is according to the type, the tonality is different and slightly differs, as rhythmic musical instrument, the harmonica can play at least two kinds of chords, high-level musician can blow out two relatively independent vocal parts simultaneously under the prerequisite of following the harmonica structure at the harmonica.

However, in the traditional low-frequency harmonica, the length and thickness of the reeds cause breath retardation, the pronunciation effect is influenced, playing is difficult, and the tone effect is not ideal.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the defects in the prior art are overcome, and the 24-hole 48-tone harmonica is smooth in breath passing, labor-saving in playing and sensitive in pronunciation reaction.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a 24 48 full scale harmonicas in sound low range in hole, includes the musical instrument check, covers the bedplate in musical instrument check both sides and covers the apron on the bedplate, installs the reed on the bedplate, goes up the corresponding installation of piece bedplate and goes up piece reed group, and lower piece bedplate corresponds installs lower piece reed group down, the reed install the both sides at the bedplate according to the difference of blowing the sound and inhaling the sound, blow the sound and install the inboard at the bedplate, inhale the sound and install the outside at the bedplate, blow the sound and inhale the sound looks interval setting, the bass district of musical instrument check set up hollow out construction, the high pitch district lower part of musical instrument check sets up the recess.

Further, the upper reed group is pressed from left to right

The lower reed group is pressed from left to right

Are arranged in order.

Furthermore, the sound leaf spring comprises a spring rake, a head part, a root part and a spring cap, wherein the total length of the sound leaf spring is spring length a, the length of the spring rake is rake length b, and the size relation between the spring length and the rake length satisfies that b is less than 1/2 a.

Furthermore, the thickness of the reed rake is 30-50 microns and gradually decreases from a bass region to a treble region.

Furthermore, the thickness of the head part is 5-18 silk meters, and the thickness of the root part is 10-17 silk meters.

Further, the arc structure extending along the breath direction is arranged below the piano lattice hole corresponding to the high-pitched region.

Further, the length c of the circular arc structure is smaller than 1/2 of the length of the corresponding grid hole.

The 24-hole 48-tone bass range diatonic harmonica has the beneficial effects that: because the thickness of the low-pitch reed is thicker than that of the high-pitch reed, the hollow structure is arranged in the low-pitch area of the piano frame, so that the situation that the vibration amplitude of the low-pitch reed collides with the piano frame hole to produce sound normally is prevented, and the breath can pass conveniently; because the gong of the high pitch is short and the breath used relatively needs to be large, the lower part of the high pitch area of the frets is provided with the groove, and the circular arc extending along the breath direction is arranged below the frets corresponding to the high pitch area, so that on one hand, the playing is more labor-saving, on the other hand, the breath transfer time can be reduced, and the pronunciation is faster; through repeated adjustment, the length and the thickness of the reed are designed more reasonably, the playing taste is more delicate, smooth and fluent, the playing is moderate in air tightness, large in volume, sensitive in pronunciation reaction and stable and easy to control, the playing timbre in the bass region is mellow in magnetism, the timbre in the midrange region is mild and soft, and the high-pitched region is clear and solid and has penetrating power.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

The 24-hole 48-tone low-pitch range gamut harmonica comprises a musical instrument lattice 1, seat plates covering two sides of the musical instrument lattice 1 and cover plates covering the seat plates, wherein the seat plates are provided with sound reeds 9, the upper sheet seat plates are correspondingly provided with upper sheet sound reed sets, the lower sheet seat plates are correspondingly provided with lower sheet sound reed sets, the sound reeds 9 are arranged on two sides of the seat plates according to different sound blowing and sound absorbing modes, the sound blowing mode is arranged on the inner sides of the seat plates, the sound absorbing modes are arranged on the outer sides of the seat plates, the sound blowing and sound absorbing modes are arranged at intervals, a low tone area of the musical instrument lattice 1 is provided with a hollow structure 4, and the lower part of a high tone area of the musical instrument lattice 1 is provided with a groove 2, as shown in fig. 1 and fig. 2.

As shown in FIG. 6, the upper reed group is pressed from left to right

The lower reed group is pressed from left to right

Are arranged in order.

As shown in FIG. 3, the sound leaf spring 9 comprises a spring rake 8, a head 7, a root 6 and a spring cap 5, wherein the total length of the sound leaf spring 9 is spring length a, the length of the spring rake 8 is rake length b, and the magnitude relation between the spring length and the rake length satisfies b < 1/2 a.

The thickness of the reed rake 8 is 30-50 silk meters, the thickness of the head part 7 is 5-18 silk meters, the thickness of the root part 6 is 10-17 silk meters, and the length and thickness design parameters of the reed are shown in fig. 7 in the implementation process.

And an arc structure 3 extending along the breath direction is arranged below the piano lattice hole corresponding to the high-pitched region.

The length c of the circular arc structure 3 is less than 1/2 of the length of the corresponding grid hole.

The 24-hole 48-tone bass range diatonic harmonica has the beneficial effects that: since the thickness of the low-pitch reed is thicker than that of the high-pitch reed, the hollow structure is arranged in the low-pitch area of the musical instrument lattice, so that the reed is prevented from blocking the musical instrument lattice holes, and the passage of breath is facilitated; because the gong of the high pitch is short and the breath used relatively needs to be large, the lower part of the high pitch area of the frets is provided with the groove, and the circular arc extending along the breath direction is arranged below the frets corresponding to the high pitch area, so that on one hand, the playing is more labor-saving, on the other hand, the breath transfer time can be reduced, and the pronunciation is faster; through repeated adjustment, the length and the thickness of the reed are designed more reasonably, the playing taste is more delicate, smooth and fluent, the playing is moderate in air tightness, large in volume, sensitive in pronunciation reaction and stable and easy to control, the playing timbre in the bass region is mellow in magnetism, the timbre in the midrange region is mild and soft, and the high-pitched region is clear and solid and has penetrating power.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
