Description

Mouth organ

Technical Field

The utility model relates to the field of musical instruments, in particular to a harmonica.

Background

The stroke of the finger press (about 5mm) is small but the moving distance of the sound-changing piece is large (about 9 mm). The distance that the tuning blade moves is large so that the blow hole can be opened to a greater extent, and a stroke of 9mm is the maximum size that the blow hole can be opened to (the inner diameter of the fretting groove is about 8.35 mm). The size of the blowing hole of the chromatic scale harmonica is closely related to the air inflow during playing, the large air inflow can bring different playing feelings and results to the playing of musical instruments, the air inflow can enable the volume to be larger, and the sound can be more vigorous. The pressing stroke of the finger of the key of the traditional chromatic scale harmonica is consistent with the size of the opening, for example, the opening is 7mm, the pressing stroke of the finger is also 7mm, and if the current opening of 9mm is reached, the pressing stroke of the finger needs to be 9 mm. The traditional chromatic harmonica is extremely disadvantageous to playing because the key stroke is large and the action radian of the fingers is larger, so that the traditional chromatic harmonica reduces the pressing stroke of the fingers by reducing the size of the blowing holes, and actually compromises the playing effect.

The present invention solves such problems, and the user can push the button assembly 300 with the palm even while holding the entire device, thereby reducing the moving distance of the fingers, improving the user's comfort, and providing convenience to the user.

The utility model well solves the problems of the background art: the pressing stroke of the finger is 5mm, and the hole opening of the blowing hole can reach 9mm at the same time. In other embodiments, the distance of finger movement can be reduced even if the size of the opening is increased.

As shown in fig. 2 and 7, in some embodiments of the present invention, the piano cabinet 100 is provided with a receiving portion for placing the button assembly 300, the receiving portion includes a sliding groove 101, a placing cavity 102 and an operation port 103, the placing cavity 102 is located at one end inside the piano cabinet 100, the sliding groove 101 is provided at the top of the piano cabinet 100 and is communicated with the placing cavity 102, and the operation port 103 is provided at a side wall of the piano cabinet 100 and is communicated with the placing cavity 102. In the present embodiment, the operation opening 103 is located near the bottom end of the organ case 100, so that the user can activate the button assembly 300 without using the index finger; the top end of the first lever 310 penetrates through the sliding groove 101, then the sound-changing piece 200 is clamped with the top of the first lever 310, and when a user operates the first lever 310, the first lever 310 moves left and right in the sliding groove 101, so that the sound-changing piece 200 is driven to move left and right.

As shown in fig. 3, 5 and 6, in some embodiments of the present invention, the button assembly 300 includes a first lever 310 and a second lever 320 that are engaged with each other, the first lever 310 is disposed in the placing cavity 102, a top end of the first lever 310 extends to the sliding slot 101, one end of the second lever 320 is connected to a bottom end of the first lever 310, another end of the second lever 320 extends to the operation opening 103, the sound-transforming plate 200 has a fastening hole 201, and the sound-transforming plate 200 is fastened to the top end of the first lever 310 through the fastening hole 201. In this embodiment, the sound-changing piece 200 is directly placed on the musical box body 100, and the first lever 310 passes through the sliding slot 101 and then passes through the fastening hole 201 to control the sound-changing piece 200.

In some embodiments of the present invention, the rotary cylinder 330 is installed in the placing chamber 102, the rotary cylinder 330 is detachably coupled to the first lever 310, and the second lever 320 is detachably coupled to the rotary cylinder 330. In the present embodiment, the first lever 310 and the second lever 320 are both connected to the rotary cylinder 330 and can rotate on the rotary cylinder 330. The manner in which the detachable connection and the rotation are possible is not limited to: the rotary cylinder 330 is provided with a section of rotary groove, and the first lever 310 and the second lever 320 which are mutually connected are clamped in the rotary cylinder 330; of course, it may be hinged. The detachable connection mode is convenient for a user to replace damaged parts, and reduces the fund consumption of replacing the whole product due to partial part defects.

As shown in fig. 4, in some embodiments of the present invention, the first lever 310 is connected to the rotary cylinder 330, and the second lever 320 includes a cap 322 and a rod 321 connected to each other, and an end of the rod 321 away from the cap 322 abuts against the first lever 310.

In the present embodiment, the first lever 310 and the second lever 320 are in a completely separated state, and the operation opening 103 is located in the middle of the musical instrument lattice body 100, and the user pushes the second lever 320, so that the end of the second lever 320 abuts against the first lever 310, and the first lever 310 pushes the sound-changing piece 200. The same way as the above-mentioned pressing, no matter the position of the second lever 320 directly contacting with human body is located at the middle or bottom, it is far away from the blowing hole of the blowing nozzle, there is no potential problem that the face is close to the key when playing high pitch, and the finger pressing has no influence of external factors at any time.

In some embodiments of the present invention, the elastic member is a torsion spring, the torsion spring extends into the first lever 310, the middle portion of the first lever 310 has a bending portion 311, the bending portion 311 is provided with a limiting post 312 for abutting against the torsion spring, and the inner side wall of the musical instrument case 100 is provided with a groove body matched with the bending portion 311.

In the present embodiment, the torsion spring is a commercially available part, and the specific type thereof is not limited herein. As shown in fig. 10, the main body of the torsion spring is wound around the fixing block inside the piano cabinet 100, one end of the spring rod abuts against the inner wall inside the piano cabinet 100, and the other end of the spring rod penetrates into the first lever 310, so that the button assembly 300 can be rebounded by the force of the torsion spring when the entire button assembly 300 is pressed. If the first lever 310 is a straight-line structure, the tuning peg 200 is difficult to push, and the limiting column 312 and the inner wall of the piano cabinet 100 have the same function and provide a stress point for the torsion spring; the groove body is positioned in the placing cavity 102, when the second lever 320 is pressed and then released, the bent part 311 of the first lever 310 can return into the groove body, and the groove body provides a position for the bent part 311 to rebound, so that the space for placing the cavity 102 is maximally utilized.
