Description

Technical Field

[0001] The utility model belongs to the technical field of chromatic harmonicas, and more specifically, relates to a chromatic harmonica with a large volume. Background Art

[0002] As a musical instrument, harmonicas are often seen in our daily life. People play wonderful music with them. However, existing harmonicas have problems in instrument hardware such as small volume and unreasonable scale arrangement. Moreover, some harmonicas cause fatigue and discomfort to players during long-term playing. Therefore, there is a need for a harmonica that can increase the volume and improve the comfort of players. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a chromatic harmonica with a large volume, which can meet the requirements of increasing the volume of the harmonica and improving the comfort during playing.

[0004] A chromatic harmonica with a large volume of the utility model includes a harmonica body, a harmonica grid installed in the harmonica body, and a pair of reed plates. The pair of reed plates are respectively located on the upper and lower sides of the harmonica grid, and one side of each is fixedly connected to the sound outlet end of the harmonica grid. The remaining parts of the pair of reed plates freely cover the upper and lower end faces of the harmonica grid and do not contact the inner wall of the harmonica body, so as to form a connected resonance box in the inner cavity of the harmonica body; the harmonica body, in cooperation with the harmonica grid and the pair of reed plates, jointly realizes the playing of the harmonica.

[0005] As a further improvement of the utility model, the harmonica body includes a plurality of reed pieces, a housing, a mouthpiece, and a tone-changing plate. The surface of the reed plate is provided with a plurality of reed holes. The heads of the plurality of reed pieces are fixedly installed on the reed plate, and the remaining parts respectively cover the plurality of reed holes. One side of the harmonica grid close to the reed pieces is slidably connected to the tone-changing plate, and one side of the harmonica grid close to the tone-changing plate is fixedly connected to the mouthpiece. One side of the pair of reed plates is respectively fixedly connected to one side of the harmonica grid close to the mouthpiece. The housing covers the harmonica grid, the plurality of reed pieces, the pair of reed plates, the mouthpiece, and the tone-changing plate and is fixedly connected to the harmonica grid; the area of the upper and lower end faces of the reed plate is enlarged, and the area of the reed plate is at least 40% larger than the area of the end face of the harmonica grid, so as to increase the sound transmission space and amplify the sound emitted by the harmonica.

[0006] As a further improvement of the utility model, the shape of the reed piece is wedge-shaped. The harmonica grid is provided with a plurality of sounding holes. The basic size of the reed piece is changed from being the same as that of the sounding hole of the harmonica grid to being larger than the basic size of the sounding hole of the harmonica grid, eliminating the howling of the high-pitched reed piece, increasing the firmness, toughness, and response sensitivity of the reed piece.

[0007] As a further improvement of the utility model, the area of the upper and lower end faces of the reed plate is enlarged so that the area of the end face of the reed plate exceeds 40% of the area of the end face of the harmonica grid. The edge of the reed plate is set as a non-linear edge, preferably a serrated edge, so as to increase the radiation range of the sound emitted by the reed piece.

[0008] As a further improvement of the present utility model, the area of the reed plate covers at least all the reed holes in terms of quantity.

[0009] As a further improvement of the present utility model, the outer shell includes an upper outer shell and a lower outer shell. The edges of the upper outer shell and the lower outer shell are buckled and fixedly connected to the fretboard through bolts respectively. A number of reinforcing ribs are provided inside the outer shell to ensure the connection stability of the chromatic harmonica. The cavity between the upper outer shell and the lower outer shell is set as a resonance box, reducing the volume of the fretboard and reversely expanding the space of the resonance box, thereby reducing the volume limitation of the fretboard on the volume.

[0010] As a further improvement of the present utility model, the tone-changing plate includes a tone-changing key and a tone-changing spring. The tone-changing key is located outside the outer shell to assist the performer in adjusting and changing the syllables. The fretboard is provided with a groove for placing the tone-changing spring, and the tone-changing plate is provided with a spring through-hole. The tone-changing spring is simultaneously stuck in the spring through-hole and the groove of the fretboard to ensure the reset of the tone-changing plate after adjustment; the tone-changing plate is provided with a number of tuning through-holes for tuning, and the tuning is achieved by blocking different positions of the fretboard. When tuning, press the tone-changing key and compress the tone-changing spring, and the tone-changing plate moves to change the position of the fretboard it blocks to achieve tuning. When finished, release the tone-changing key, and the tone-changing spring rebounds under the elastic force, and the tone-changing plate resets.

[0011] As a further improvement of the present utility model, in a further embodiment, as shown in the figure, the reed holes are set as asymmetric, optimizing the size of the harmonica reed holes and the length of the air ducts in the fretboard. Each group consists of eight reed holes, and the length changes of each group of reed hole sizes are the same, enhancing the rhythm of the harmonica sound.

[0012] As a further improvement of the present utility model, the outer shell is provided with sound outlet holes, and the sound outlet holes are set in the shape of piano keys, closing the existing open sound outlet hole part to form a complete harmonica resonance box.

[0013] As a further improvement of the present utility model, the edge of the outer shell extends beyond the width of the mouthpiece and the outer shell forms a wrapped edge structure for the mouthpiece, closing the air leakage points formed by the separation of the harmonica mouthpiece and the outer shell, making the performance more labor-saving; reducing the thickness of the mouthpiece is beneficial for playing large-scale pieces with a long performance time and extending the time when the performer feels fatigue.

[0014] As a further improvement of the present utility model, it further includes a bottom column. The outer shell is connected to the bottom column on the side away from the mouthpiece, relieving the fatigue and pain of the performer holding the harmonica during long-term performance and preventing the phenomena of slipping and dropping; the connection between the bottom column and the outer shell is a detachable connection, facilitating flexible installation and disassembly to meet the needs of different performers for the bottom column.

[0015] As a further improvement of the present utility model, a signal bead is provided on the mouthpiece, and the signal bead is fixed at the position of the first note of three octaves, ensuring that without affecting the performance, it effectively prompts the performer of the position where the harmonica is held.

[0016] As a further improvement of the present utility model, as shown in Table 1 and Table 2, the syllable arrangement of the existing chromatic harmonica is adjusted to make the blowing and sucking relationship of the harmonica more reasonable. The continuous sucking or blowing of the syllables within each octave is changed to blowing and sucking for each syllable within each octave, which is more conducive to playing music with long blowing, especially long sucking notes, and is more conducive to beginners of the harmonica to master the playing skills of the harmonica, and is conducive to the popularization and teaching of the harmonica and music.
