Description

Technical Field

[0001] This utility model relates to a harmonica, specifically a 15-hole folk blues harmonica. Background Technology

[0002] The blues harmonica, also known as a diatonic harmonica, or a "folk harmonica" or "Blues Harp," is typically around 10cm in length, though some models may be slightly larger or smaller. The blues harmonica is extremely popular in Europe and America, and represents the largest group of harmonica enthusiasts.

[0003] Currently, most blues harmonicas on the market are 10-hole and can only produce 20 notes, unable to produce ultra-low frequencies. When band performances require ultra-low frequencies, the harmonica needs to be changed, which is very inconvenient for users. Furthermore, existing blues harmonicas are difficult to assemble and disassemble; the reeds are welded or die-cast onto the reed plate, making replacement difficult when a reed is damaged, especially the high-pitched reeds, which are long and vibrate at high frequencies, making them prone to damage during use. Once damaged, they cannot be repaired, causing further inconvenience to users. Therefore, the inventor designed a 15-hole folk blues harmonica. Utility Model Content

[0004] The purpose of this utility model is to provide a 15-hole folk blues harmonica, which has the advantages of simple structure, reasonable design, convenient disassembly and maintenance of reeds, and is equipped with a sub-bass zone, capable of producing 30 notes, meeting the diverse needs of users, and solving the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 15-hole folk blues harmonica, comprising a body and an upper cover and a lower cover disposed on the body. The body includes a frame, an upper spring plate, and a lower spring plate. The frame has 15 grooves along its length. The upper and lower spring plates are respectively disposed on the upper and lower end faces of the frame, and each has an upper and lower perforated hole. The upper and lower reeds are detachably installed via reed screws. The upper and lower reeds form an angle α with the upper and lower reed plates, respectively, and are attached to the upper and lower openings of the soundbox. A sound hole is formed on the front face of the soundbox. The sound hole can produce 30 different notes and consists of a sub-bass, bass, mid-range, and treble range, which are arranged on the instrument body from left to right.

[0006] Preferably, a baffle is provided on the rear side of the instrument body between the upper cover and the lower cover, and decorative strips are etched at both ends of the baffle.

[0007] Preferably, the upper and lower end faces of the baffle are provided with protruding strips along their length direction. The protruding strips are integrally die-cast with the baffle and are inserted into the grooves on the upper and lower spring plates.

[0008] Preferably, the depth of the settling tank is between 2mm and 8mm.

[0009] Preferably, the top cover and the bottom cover are detachably mounted on the instrument body using a first screw.

[0010] Preferably, the upper spring plate and the lower spring plate are detachably mounted on the lever by a second screw.

[0011] Preferably, the upper and lower springs are the same size, and the upper and lower springs decrease in length along the length direction of the upper and lower spring plates, and the upper and lower springs can vibrate and produce sound under the action of external force.

[0012] Preferably, the included angle α is between 1° and 35°.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a 15-hole folk blues harmonica. The harmonica includes a body and an upper cover and a lower cover mounted on the body. The body includes a frame, an upper spring plate, and a lower spring plate. Fifteen grooves are provided on the frame along its length. The overall structure is simple and reasonably designed. Upper and lower hollow holes are respectively provided on the upper and lower spring plates. Upper and lower springs are detachably installed at the upper and lower hollow holes by means of spring screws. Compared with traditional welded or one-piece molded springs, it is easier for users to maintain and replace, and is more practical. An angle α is formed between the upper and lower springs and the upper and lower spring plates. The angle α is between 1° and 35°. The purpose of setting the angle is that when the user sucks or blows the harmonica, both the upper and lower springs will vibrate and produce sound.

[0015] 2. During installation, the upper and lower springs of this invention are respectively attached to the upper and lower openings of the soundbox, and a blow hole is formed on the front end face of the soundbox. This blow hole can produce 30 different notes. The blow hole consists of a sub-bass range, a bass range, a mid-range range, and a treble range. The sub-bass range, bass range, mid-range range, and treble range are arranged on the instrument body from left to right. Compared with the existing ten-hole blues harmonica, it has stronger functionality. Attached Figure Description
