Brassica instrument with scale marks and used for adjusting intonation height

Abstract

The utility model discloses a brass instrument with scale marks for adjusting intonation, which relates to the field of brass instruments and comprises a tube body, one end of the tube body is provided with a horn mouth, the other end of the tube body is communicated with a sound tube, the other end of the sound tube is fixedly communicated with a horn mouth, a piston is fixedly mounted in the sound tube, and the horn mouth is fixedly connected with the tube body. A piston key is movably installed outside the piston, and an adjusting pipe is movably installed at the joint of the sound pipes. When the pipe body is held by hand and playing is carried out through the horn mouth, the piston key is pressed by hand to control the piston so as to adjust the playing intonation, and the adjusting pipe is pulled outwards along the sound pipe so that the adjusting pipe drives the sealing plug to move outwards along the inside of the sound pipe so as to adjust the playing intonation. The reference scales arranged outside the upper and lower parts of the adjusting tube are exposed out of the sound tube in the moving process, and the distance of the adjusting tube in the sound tube is controlled by observing the reference scales as a reference to adjust the pitch, the frequency tone and the intonation in use, so that the limitation is reduced.

Description

Technical Field

[0001] The utility model relates to the field of brass instruments, in particular to a brass instrument with scale marks for adjusting pitch. Background Art

[0002] Brass instruments are lip-vibrating wind instruments, including tubas, trumpets, trombones, French horns, etc. Most of them use copper tubes, funnel-shaped mouthpieces, large bells, which are sometimes detachable, and have keys on the outside. One of the keys is used to change the fingering tonality. It can produce loud brass sounds and soft woodwind sounds. It can be used in woodwind quintets. The sound is soft and full, and can be well integrated with the sound of woodwind and string instruments. It is a widely used instrument. The existing technology has the following problems:

[0003] 1. Existing brass instruments with scale marks for adjusting pitch, when playing, play music through the player's playing skills and breath adjustment in conjunction with key operations, but the instrument is inconvenient to adjust the pitch, frequency, pitch and pitch of the instrument when in use, and it is not convenient to use and adjust in different occasions, there is no specific reference, and there are certain limitations. Utility Model Content

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A brass instrument with scale markings for adjusting pitch, comprising a tube body, a mouthpiece provided at one end of the tube body, a sound tube connected at the other end of the tube body, a mouthpiece fixedly connected at the other end of the sound tube, a piston fixedly installed inside the sound tube, a piston key movably installed outside the piston, an adjustment tube movably installed at the connection of the sound tube, the adjustment tube and the sound tube are sealed, and a reference scale is provided on the outside of the adjustment tube.

[0006] A further improvement of the technical solution of the utility model is that a sealing plug connected to the regulating tube is movably clamped inside the sound tube, and the sealing plug is sealedly connected to the sound tube and the regulating tube.

[0007] A further improvement of the technical solution of the utility model is that a slide groove matched with the sealing plug is provided inside the sound tube, and the regulating tube can move along the slide groove.

[0008] A further improvement of the technical solution of the utility model is that: the regulating tube is arranged in a U shape.

[0009] A further improvement of the technical solution of the utility model is that the outer wall of the regulating tube and the inner wall of the sound tube are in contact with each other.

[0010] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0011] 1. The utility model provides a brass instrument with scale markings for adjusting the pitch, which is provided with a sound tube, an adjusting tube, a reference scale, a sealing plug, etc. When a performer holds the tube body and plays through a mouthpiece, he controls the piston by pressing a piston key to adjust the playing tone, and pulls the adjusting tube outward along the sound tube to drive the sealing plug to move outward along the inside of the sound tube. The reference scales arranged on the upper and lower outer parts of the adjusting tube are exposed to the outside of the sound tube during the movement, and the distance of the adjusting tube inside the sound tube is controlled by observing the reference scale as a reference to adjust the pitch, frequency, tone and pitch during use, thereby facilitating flexible adjustment according to actual usage scenarios and reducing limitations in use.

[0016] The present invention is further described in detail below in conjunction with the embodiments:

[0017] Example 1

[0018] like Figure 1-3 As shown, the utility model provides a brass instrument with scale markings for adjusting pitch, comprising a tube body 1, a horn 2 is arranged at one end of the tube body 1, a sound tube 6 is connected to the other end of the tube body 1, a mouthpiece 5 is fixedly connected to the other end of the sound tube 6, a piston 3 is fixedly installed inside the sound tube 6, a piston key 4 is movably installed outside the piston 3, an adjusting tube 7 is movably installed at the connection of the sound tube 6, the adjusting tube 7 and the sound tube 6 are sealed, and a reference scale 8 is provided on the outside of the adjusting tube 7; a sealing plug 9 connected to the adjusting tube 7 is movably clamped inside the sound tube 6, and the sealing plug 9 is sealed to the sound tube 6 and the adjusting tube 7; a sliding groove matched with the sealing plug 9 is provided inside the sound tube 6, and the adjusting tube 7 can move along the sliding groove; the adjusting tube 7 is arranged in a U shape; the outer wall of the adjusting tube 7 and the inner wall of the sound tube 6 fit each other.

[0019] In this embodiment, the sound tube 6, the adjusting tube 7, the reference scale 8, the sealing plug 9, etc. are provided. When the performer holds the tube body 1 and plays through the mouthpiece 5, he controls the piston 3 to adjust the playing tone by pressing the piston key 4 with his hand. By pulling the adjusting tube 7 outward along the sound tube 6, the adjusting tube 7 drives the sealing plug 9 to move outward along the inside of the sound tube 6. The reference scale 8 provided on the upper and lower outsides of the adjusting tube 7 is exposed to the outside of the sound tube 6 during the movement. By observing the reference scale 8 as a reference, the distance of the adjusting tube 7 inside the sound tube 6 is controlled to adjust the pitch, frequency, tone and intonation, thereby facilitating flexible adjustments according to actual usage scenarios and reducing limitations of use.

[0020] The following is a detailed description of the working principle of the brass instrument with scale markings for adjusting the pitch.

[0021] like Figure 1-3 As shown, when the performer holds the tube body 1 and plays through the mouthpiece 5, he controls the piston 3 to adjust the playing tone by pressing the piston key 4 with his hand, and pulls the adjusting tube 7 along the sound tube 6 to make the adjusting tube 7 drive the sealing plug 9 to move outward along the inside of the sound tube 6. When the pitch is low, the adjusting tube 7 is pushed inward along the sound tube 6 to enter the inside of the sound tube 6 to increase the pitch. When the pitch is high, the adjusting tube 7 is pulled outward along the sound tube 6 to expose the inside of the sound tube 6 to lower the pitch. The reference scales 8 set on the upper and lower outer parts of the adjusting tube 7 are exposed to the outside of the sound tube 6 during the activity, and the distance between the adjusting tube 7 and the inside of the sound tube 6 is controlled by observing the reference scale 8 as a reference to adjust the pitch, frequency, tone and pitch during use.

[0022] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
