Abstract

The utility model relates to an adjustable regulating tube for a clarinet of some musical instrument. The regulating tube consists of an outer tube internally fitting an inner tube. A plate is pin-arranged on the surface. A spring is positioned between one inner end of the plate and the outer tube. Latches, arranged on the other end of the plate, can pass through the outer tube and catch the grooves on the inner tube wall. An upper tube containing a mouthpiece is connected with the inner tube. By slightly pressing the plate, the clarinet can be easily tuned with several sections of length variation and at least one semitone of quarter tone can be changed, thus, additional procurement for shorter regulating tube due to poor tune is not required, so as to simplify the tuning process. It is suitable for students. Situations of air flow interference and spit accumulation are improved. Gaps become shallower, so as to prevent spit accumulation and interference of air flow.

Description

The adjustable adjustable pipe of clarinet

Technical field

The utility model relates to a kind of adjustable pipe of clarinet toneable of musical instrument, relate in particular to a kind of length variations that adjusts multistage, and can change the above adjustable pipe of a semitone that pitch reaches four fens, this adjustable pipe is installed in the clarinet, is a kind of tuning device.

Background technology

(for example: clarinet), a kind of for musical instrument is because clarinet (clarinet) can be for being played out euphony by the people, so clarinet can by the student or social personage likes and and then buy use for clarinet.

As shown in Figure 9, clarinet for a kind of traditional structure, this structure is provided with a clarinet 60, its top is provided with the socket part 61 of tool cork, a sheathed adjustable pipe 70 on it, upper and lower of this adjustable pipe 70 has a low groove 71 and a upper groove 72 respectively, low groove 71 and socket part 61 mutual sockets;

The socket part 81 of one bottom tool cork can be socketed in the upper groove 72, and be provided with in last pipe 80 tops can be for the mouthpiece 82 of blowing, still, above-mentioned traditional type be configured in actual use the time, but have following shortcoming:

1. when adjustable pipe 70 during in tuning (as shown in Figure 10), if accuracy in pitch is higher, need adjustable pipe 70 whole joints are extracted one section suitable distance up, whole pitch is descended, to reach required accuracy in pitch,, need to buy more again the short adjustable pipe of length if accuracy in pitch is on the low side, whole pitch is risen, when playing wind instruments, exist the quite shortcoming of inconvenience.

2. when adjusting, damage cork easily with last pipe 80 joints, and also need to readjust the mouthpiece position, process is quite complicated, another bigger influence is: crack 62 between forming quite deeply between the inner tubal wall of adjustable pipe 70 meeting socket pipe 61 of tool cork on clarinet 60 after extracting, this gap 62 causes the flow-disturbing after the air blowing easily and builds up the saliva problem, and very inconvenience on using has in addition improved necessity in fact.

Summary of the invention

The shortcoming that the utility model use to go up exists in reality in view of the aforementioned conventional structure and being redesigned is designed the adjustable adjustable pipe of a kind of clarinet.

Fundamental purpose of the present utility model provides the adjustable adjustable pipe of a kind of clarinet, when when adjusting, only need the applying light pressing board, can adjust the length variations of most sections, and can change pitch and reach four minutes one more than the semitone, release needs additionally to buy the short adjustable pipe of length because of accuracy in pitch is on the low side, the process of tuning is simplified and easy to use, use to be suitable for the student, and can improve flow-disturbing and build up the saliva problem, so that the degree of depth in gap shoals, be difficult for building up saliva, also less to the interference of air blowing air-flow.

In order to reach the purpose of aforesaid utility model, the technological means of being used is to provide a kind of clarinet adjustable adjustable pipe, mainly establish pipe composition in the outer tube internal sleeve, a slice pressing board should outer tube-surface be pivoted, between pressing board one medial extremity and outer tube spring is set, another side of pressing board is provided with several latches, and it can penetrate outer tube and folder is pulled on several set on inner pipe wall chases, engages the pipe of going up of tool mouthpiece on the interior pipe;

When needing tuning, only need the applying light pressing board, just can adjust the length variations of most sections, and can change pitch and reach four minutes one more than the semitone, exempt needing additionally to buy the adjustable pipe of length because of accuracy in pitch is on the low side than weak point, the process of tuning is simplified and easy to use, use to be suitable for the student, and can improve flow-disturbing and build up the saliva problem, so that the degree of depth in gap shoals, be difficult for building up saliva, also less to the interference of air blowing air-flow.
