Description

Technical Field

[0001] The utility model belongs to the technical field of organ sound pipe structures, in particular to an anti-corrosion organ sound pipe structure. Background Art

[0002] In the organ, the sound pipe is a very important component. It is the basis of sound production. The sound pipe is divided into whistle pipe and reed pipe. The whistle pipe has a cylindrical body and a conical foot. The sound production principle is very similar to that of the flute in the orchestra. The airflow enters from the root of the whistle pipe, and the air is used to produce different frequencies and pitches in the pipes of different lengths to achieve the performance effect. The long one plays the bass and the short one plays the treble. The reed pipe is equipped with a metal reed in the conical body to produce sound. In addition to its own timbre, it can also produce timbre similar to that of brass and woodwind solos. Among them, the whistle pipe accounts for a larger proportion, and its material, shape, diameter and other characteristics will affect the timbre of the sound produced by the organ. The sound produced by the reed pipe is louder than that of the whistle pipe, and the timbre changes are also richer than that of the whistle pipe. In the performance, the overtones of the sound produced by the reed pipe are generally much more than those of the whistle pipe.

[0003] Traditional sound pipes for pipe organs do not have convenient tuning measures, the mouthpieces are complex to process, and the overall structure is complex. Considering the complexity of the seaside environment, the sound pipes used in wave sound-generating devices require convenient tuning measures and a simplified overall structure. The processing of new material mouthpieces requires innovation. Utility Model Content

The arc edge line of the mouth piece 4 contacts the inner wall of the cylindrical tube body 1 without a gap, and there is a gap between the upper surface of the mouth piece 4 and the bottom end of the elliptical piece a2.
