PROBLEM TO BE SOLVED: To provide a horn resonant tube capable of outputting a chord with a sufficient sound pressure.SOLUTION: A horn resonant tube 2 mounted on a vehicle makes a first sound which is generated by vibration of a diaphragm 11 and which has a first frequency as a fundamental frequency resonate with a second sound which is generated by vibration of the diaphragm 11 and which has a second frequency as a fundamental frequency and a relation with the first frequency as a chord. The resonant tube includes a main resonant tube 21 to which a chord including the first sound and the second sound are inputted to make the first sound resonate, and a branch resonant tube 22 which branches from the main resonant tube 21 and which makes the second sound resonate. The main resonant tube 21 is arranged on a first surface 11a of the diaphragm 11, and the branch resonant tube 22 branches on the first surface 11a from the main resonant tube 21 and is arranged on a second surface 11b opposite to the first surface 11a of the diaphragm 11.SELECTED DRAWING: Figure 3

    【課題】本発明は、十分な音圧を持つ和音を出力できるホーンの共鳴管を提供することを目的とする。【解決手段】振動板11の振動により発生し、第1周波数を基本周波数とする第1音と、振動板11の振動により発生し、第1周波数と和音の関係を持つ第2周波数を基本周波数とする第2音とをそれぞれ共鳴させ、車両に搭載されるホーンの共鳴管2であって、第1音と第2音とを含む和音が入力され、第1音を共鳴させる主共鳴管21と、主共鳴管21から分岐し、第2音を共鳴させる分岐共鳴管22と、を備え、主共鳴管21は、振動板11の第1面11aに配置され、分岐共鳴管22は、第1面11a上で主共鳴管21から分岐し、振動板11の第1面11aとは反対側の第2面11bに配置される。【選択図】図3
