| titleOfInvention | Tone chamber's component of whistle and whistle |
| abstract | The utility model discloses a kind of tone chamber's component of whistle and whistles, tone chamber's component of whistle includes being distributed in conplane at least two keynotes chamber and whistle mouth, the end of each keynote chamber offers blow vent, blow vent is communicated with the gas channel that enters of whistle mouth, separated between adjacent keynote chamber by separator, the vertical section of keynote chamber is in ellipsoid like structure, the length extending direction a at an acute angle of guiding surface and keynote chamber where the blow vent of keynote chamber；The vertical section of keynote chamber is in ellipsoid like structure, the length extending direction a at an acute angle of guiding surface and keynote chamber where the blow vent of keynote chamber, above structure makes that friction and high-frequency vibration occur when entering keynote chamber from the compressed air stream that gas channel enters that enters of whistle mouth, to issue high-frequency sound；And separated between adjacent keynote chamber by separator, which can prevent the turbulent flow at keynote cavity edge, while prevent the interference between two neighboring keynote chamber. |
