PROBLEM TO BE SOLVED: To provide a speaker device that causes less deformation even when an external force is applied to a piezoelectric film. SOLUTION: The speaker device 10 includes a film diaphragm 20 formed by a film 21 as a base material and for vibrating the film 21 to generate sound, and a support mechanism 50 for supporting the film diaphragm 20. The support mechanism 50 is provided with a structure 54. The structure 54 faces one side of the film diaphragm 20 at a distance enough to flexibly restore deformation caused by the external force.
