Embodiment Construction

[0013] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, but the present embodiments are not limited to the present invention, and any similar structures and similar changes of the present invention should be included in the protection scope of the present invention.

[0014] figure 1 An implementation form according to the present invention is shown, which includes: the air pump 1 generates air to the adjustable duckbill 3 through the air duct 2 . Adjustable duckbill 3 is fixed on the support 4. Adjusting screw 5 can control the height and angle of adjustable duckbill 3, and adjusting push rod motor 7 can control the position of piston 8, so as to accurately control the tube length of single tube 6. Start the air pump 1, which generates gas with a controllable flow rate, flows out through the adjustable duckbill 3, excites the single tube 6, and emits an air-sounding sound with a stable frequency. ...

Abstract

The invention discloses an air-sounding single-tube blowing control device which can be used for researching the correction value of the orifice of an air-sounding musical instrument, and can also beused for researching the influence of physical parameters such as a blowing position, an air flow velocity, a tube body length and the like on the air-sounding audio characteristics. The device is composed of an air pump, an adjustable duckbilled mouthpiece, a controllable long single tube and the like. The air pump generates air with controllable flow velocity, and the air flows out through the adjustable duckbilled mouthpiece to excite the single tube to make a buzzing sound; the length of the single tube is accurately set by controlling the position of a damping piston through a push rod motor to generate a specific sound signal. The device has the characteristics of stable sound effect, scientific structure, simple operation, multiple purposes and the like.

Description

technical field [0001] The invention relates to an edge-sound and air-sounding sounding device, which relates to the technical field of musical instruments, in particular to a stable sounding device with specific audio properties and with controllable airflow velocity, mouthpiece angle and single tube length. Background technique [0002] The audio characteristics of brass instruments such as Chinese flute, Xiao, or Western trumpets are related to their shapes and specifications. However, "the sound of bamboo cannot be tuned", when the flute is played, the air column in the tube is excited by the mouth wind to vibrate. At this time, the length of the air column in the tube is not strictly equal to the actual physical tube length, and the mouth of the tube needs to be corrected. Although the structure of the flute is simple, there are many factors that can affect the temperament. Therefore, the calculation of the mouth correction amount is very complicated. Scientific orific...
