Problems solved by technology

[0002] At present, there are many kinds of flutes used as sound instruments, mainly electric flute, electronic flute and air flute. Sound, so the air whistle is still the main one at present. According to the sounding principle, the diaphragm vibration is the main sound generation. The elastic diaphragm is driven by compressed air to vibrate, which causes the air near the diaphragm to vibrate, thereby producing sound. However, this The sound produced by the vibration is relatively dull, and the transmission distance is short, so it is not effective as a whistle warning

Embodiment Construction

[0008] Such as figure 1 As shown, the present invention is a rotor-type air whistle, which includes a bell mouth 1 and a body 2, and the bell mouth 1 and the body 2 are connected as a whole, and the bell mouth is 90 degrees, and is gradually opened, so that the whistle Change the direction and diffuse. There is a central axis in the body 2. Along the central axis, a rotor, a stator and a guide seat are arranged from bottom to top. The stator is connected and fixed to the body 2. Corresponding Longitudinal grooves, the circumferential surfaces of the rotor and the stator are provided with a plurality of longitudinal grooves, the longitudinal grooves on the rotor and the stator longitudinal grooves on the stator are in the opposite direction, the longitudinal grooves of the rotor and the stator are inclined grooves, each inclined The groove and the central axis form a certain angle. After the compressed air enters from the bottom of the body 2, it goes out from the stator chute ...

Abstract

The invention discloses a rotor type air whistle, which comprises a horn opening (1) and a body (2) which are connected into a whole, wherein a central shaft is arranged in the body (2); a rotor, a stator and a guide seat are arranged from bottom to top along the central shaft; the stator is fixedly connected with the body (2); corresponding longitudinal slots are formed on the circumferential surfaces of the rotor and the stator; and an air inlet (8) is formed at the bottom of the body (2). According to the rotor type air whistle, compressed air is used as power; the rotor type air whistle is electrically controlled to be started and make sounds in a manner that the rotor rotates at high speed; and the rotor type air whistle has the advantages of complete function, good sounding effect and the like.

Description

technical field [0001] The invention relates to a rotor type air whistle. Background technique [0002] At present, there are many kinds of flutes used as sound instruments, mainly electric flute, electronic flute and air flute. Sound, so the air whistle is still the main one at present. According to the sounding principle, the diaphragm vibration is the main sound generation. The elastic diaphragm is driven by compressed air to vibrate, which causes the air near the diaphragm to vibrate, thereby producing sound. However, this The sound produced by the vibration is relatively dull, and the transmission distance is short, so it is not effective as a siren warning. Contents of the invention [0003] In order to solve the above problems, the present invention provides a rotor-type air whistle, which uses compressed air as the power, electronically controls the starting mode and the rotor rotates at high speed to produce sound, and has the advantages of complete functions and...
