Description

Blowing nozzle structure

Technical Field

The utility model relates to a technical field in the aspect of musical instrument indicates especially one kind and can supply to play the person and can demonstrate various special effects easily to can make tone quality more full, thick and full, mellow and make the tone quality more clear blow nozzle structure person moreover.

Background

The common wind instrument mainly blows air into the instrument through a mouth to drive the air in the instrument to vibrate and make sound, however, because the pipe walls on two sides inside the blowing nozzle structure of the common wind instrument are smooth surfaces, the air can directly pass through the blowing nozzle after entering the blowing nozzle without generating air resistance and other effects, so that a player needs to exert various special effects and tastes by using various complicated playing techniques with more effort. And the blown sound quality is not full, thick, mellow and not clear enough.

In view of the above, the present invention provides a method for designing a light emitting device, which is capable of solving the above problems and developing the light emitting device by actively researching and improving the light emitting device.

SUMMERY OF THE UTILITY MODEL

The utility model discloses mainly lie in solving the person of playing who exists of current mouthpiece structure and need more difficultly and utilize various complicacies to play the skill and just can demonstrate various special effects, moreover blow off tone quality not enough full, bold, mellow and full and tone quality not clear enough problem.

In order to achieve the above object, the utility model adopts the following technical scheme:

a blow nozzle structure is characterized in that: the interior of the air duct is provided with a through air duct, one end of the air duct is provided with a blowing opening communicated with the exterior, one end of the blowing nozzle opposite to the blowing opening is provided with a connecting part for butt joint with the instrument main body, the lower side surface of the air duct at the blowing opening is provided with an inclined plane-shaped reflecting surface, two opposite side walls are provided with two symmetrical concave arc grooves, and each concave arc groove is internally provided with at least one convex rib which extends to two opposite sides along the wall surface of the groove and along the axial direction of the blowing nozzle.

The two concave arc grooves are spherical.

The convex rib is provided with two inclined planes with the tops connected.

The cross section of the convex rib is triangular.

The cross section of the convex rib is semicircular.

The convex rib is arranged at the center of each concave arc groove and divides the concave arc groove into an upper half part and a lower half part.

The utility model provides a blow gun structure, can rely on the structural design of a double-phase at least fin on this two concave arc groove to the lateral wall symmetry and the cell wall of each concave arc groove, make the gaseous flow that blows in through these two concave arc groove departments, the usable guide of these some fins of air current of both sides, and make the air current along the groove wall law direction air cock central authorities of these two concave arc grooves, and then produce to middle extrusion concentrated effort to the air current of blowing in gaseous central department, so as to cause the air lock effect, and then make the person of playing play can rely on the air lock effect that inside produced when playing and comparatively laborsaving, and can consequently demonstrate various special effects and taste easily, and need not more difficultly to use various more complicated techniques of playing, consequently, very suitable beginner. In addition, when the airflows on the two sides generate concentrated acting force towards the middle extrusion to the central airflow, the central airflow can resist to form reaction force, and the airflows on the two sides form cyclones at the two concave arc grooves respectively, so that a better resonance effect is generated, the tone quality is fuller, thicker and more mellow, and the convex ribs are utilized to regularly guide the central airflow, and the tone color is clearer.

Description of reference numerals: 10-an air duct; 11-a reflective surface; 12-a concave arc groove; 13-a rib; 20-blowing mouth; 30-a connecting part.

Detailed Description

Referring to fig. 1 to 5, a through air duct 10 is provided inside the mouthpiece structure of the present invention, a mouthpiece 20 connected to the outside is formed at one end of the air duct 10, a spring (not shown) is mounted on the mouthpiece 20, and a connecting part 30 is provided at the opposite end of the mouthpiece 20 for connecting to the instrument body. The lower side surface of the air duct 10 at the mouthpiece 20 is formed with a reflection surface 11 in the form of an inclined plane, two symmetrical and spherical concave arc grooves 12 are formed on two opposite side walls, at least one convex rib 13 extending along the groove wall surface to two opposite sides along the axial direction of the mouthpiece is arranged in each concave arc groove 12, and the convex rib 13 has two inclined planes connected at the top to make the cross section of the convex rib generally in the shape of a triangle. In the present embodiment, each of the concave arc grooves 12 is preferably provided with a convex rib 13 at the center for dividing the concave arc groove 12 into upper and lower halves.

In the present invention, the cross-sectional shape of the protruding rib 13 may be other shapes such as a semicircular shape … ….

Please refer to fig. 6, when the player blows the air into the wind channel 10 through the blowing opening 20, the blown air can flow through the two concave arc grooves 12 by the structural design of the two concave arc grooves 12 symmetrical to the opposite side walls and the at least one protruding rib 13 on the groove wall of each concave arc groove 12, the air flows on the two sides can be guided by the protruding ribs 13, and the air flows can be guided to the center of the air nozzle along the groove wall of the two concave arc grooves 12, so as to generate a concentrated squeezing force to the middle for the air flow at the center of the blown air, thereby resulting in better air resistance effect, and further enabling the player to play with more effort by the air resistance effect generated inside, thereby easily exhibiting various special effects and tastes without using more effort and using various complicated playing techniques, thereby being very suitable for beginners. In addition, when the air flows on the two sides generate concentrated acting force to the central air flow, the central air flow can generate resistance to form reaction force, and the air flows on the two sides respectively form cyclones at the two concave arc grooves 12, so that a better resonance effect is generated, the tone quality is fuller, thicker and more mellow, and the rib is utilized to regularly guide the central air flow to concentrate and more clear.
