Description

Technical Field

[0001] This utility model relates to the field of harmonica technology, and in particular to a harmonic harmonica. Background Technology

[0002] The harmonica is a multi-reed instrument that produces sound by blowing or inhaling air, causing metal reeds to vibrate. In terms of instrument classification, it belongs to the free-reed wind instrument category.

[0003] Traditional harmonica, as follows Figure 1 As shown, the instrument mainly consists of a body, a first reed plate, a second reed plate, an upper cover plate, and a lower cover plate. The body has a comb-like structure with multiple air channels along its length, all of which penetrate the upper and lower surfaces of the body. The first reed plate is fixed to the upper surface of the body and has multiple first holes C that communicate with the multiple air channels. The second reed plate is fixed to the lower surface of the body and has multiple second holes C that communicate with the multiple air channels. The upper cover plate is fastened to the first reed plate, and the lower cover plate is fastened to the second reed plate. In actual performance, air is blown or drawn into the air channels, and the air is either blown out through the first holes C or drawn in through the second holes C, producing beautiful sounds.

[0004] However, relying solely on the vibration of the reeds results in a relatively small volume of sound, which is insufficient for performances in larger venues. Furthermore, the vibration of the reeds produces a lot of extraneous noise, leading to a hoarse and unpleasant sound.

[0005] Therefore, how to design a harmonic harmonica with high volume, low noise, and melodious sound is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This invention provides a harmonic harmonica that solves the technical problems of existing harmonicas having low volume and excessive noise.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a harmonic harmonica, comprising: a fretboard, two reeds, and two covers.

[0008] The violin frame has multiple air holes on one side, and multiple ventilation holes at its top and bottom that are respectively connected to the air holes. The two reeds are respectively fixed to the top and bottom of the violin frame, and each has multiple spring holes that are respectively connected to the ventilation holes. The violin frame has air grooves at the top and bottom of the outer periphery of the two reeds, so that when the two reeds vibrate and produce sound, the air inside the air grooves vibrates and generates harmonic vibration. The two violin covers are respectively arranged opposite to the two reeds and are respectively fixed to the top and bottom of the violin frame.

[0009] The beneficial effects of this utility model are: it improves the traditional harmonica structure by first placing two reeds at the top and bottom of the frame, and then setting air grooves at the top and bottom of the frame corresponding to the outer periphery of the two reeds. When the two reeds vibrate and produce sound, they can vibrate the air inside the air grooves, generating harmonic vibrations and increasing the volume of the two reeds, thereby increasing the volume of the harmonica and meeting the needs of performance in larger scenarios.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the depth of the air duct is 0.05 to 0.1 mm.

[0012] The further beneficial effect of adopting the above method is that after the reed plate and the brace are attached, except for the surface required for sealing, the rest is suspended 0.05 to 0.1 mm above the brace. This prevents premature harmonic attenuation due to the different frequencies of the reed plate and the brace.

[0013] Furthermore, it also includes two filter plates, which are respectively located on one side of the two piano covers corresponding to the reeds and are respectively fixed on the two piano covers to filter the set sound frequencies.

[0014] The further beneficial effect of adopting the above is that by placing the two filter boards on the side of the harmonica cover corresponding to the reeds, the set sound frequencies can be filtered out when the reeds vibrate and produce sound, thus filtering out noise and improving the sound quality of the harmonica.

[0015] Furthermore, both filter plates are arc-shaped structures arranged along the width direction of the zither, and one side corresponding to the reed is a concave arc-shaped surface.

[0016] A further beneficial effect of the above is that changing the arc angle of the two filter plates can change the filtered audio frequency.

[0017] Furthermore, the thickness of both filter plates is 0.8–2.0 mm.

[0018] Furthermore, both filter boards are made of wood, metal, or plastic.

[0019] Furthermore, the set sound frequency is 600–1200 Hz. Attached Figure Description
