PROBLEM TO BE SOLVED: To provide a speaker device for a vehicle which can generate sound with high quality and wide directivity with a simple structure.SOLUTION: A speaker device 2A for a vehicle comprises: roof frames 40-3 and 40-6 constituting a compartment, which is crewman space 4 of a vehicle C; and oscillators 50-1 and 50-2 attached to the roof frames 40-3 and 40-6 and making the roof frames 40-3 and 40-6 generate sound by generating vibration and vibrating the roof frames 40-3 and 40-6. The roof frames 40-3 and 40-6 form a closed section with a first side located inside the compartment, a second side located outside the compartment, and a third side and a forth side connecting the ends of the first side and the second side. The oscillators 50-1 and 50-2 are attached to one of the first side, second side, third side and forth side.SELECTED DRAWING: Figure 2 【課題】高品質で広い指向性を持つ音を簡易な構成で発生することが可能な車両用スピーカ装置を提供する。【解決手段】車両用スピーカ装置２Ａは、車両Ｃの乗員空間４である車室を構成するルーフフレーム４０−３，４０−６と、ルーフフレーム４０−３，４０−６に取り付けられており、振動を発生することによってルーフフレーム４０−３，４０−６を振動させてルーフフレーム４０−３，４０−６に音を発生させる振動子５０−１，５０−２と、を備え、ルーフフレーム４０−３，４０−６は、車室内側の第一面と、車室外側の第二面と、第一面及び第二面の端部同士を繋ぐ第三面及び第四面と、によって閉断面を構成しており、振動子５０−１，５０−２は、第一面、第二面、第三面及び第四面のいずれかに取り付けられている。【選択図】図２
