(EN) Provided is a small and lightweight speaker device that generates sound in a frequency band exceeding the audible band. A first piezoelectric actuator for converting a first frequency signal in the audible band into an audible sound, a second piezoelectric actuator for converting a second frequency signal in a frequency band higher than the audible band into a high frequency sound, a first piezoelectric actuator and a second Provided is a speaker device including a housing part provided with a piezoelectric actuator. The housing portion may include a plate portion provided with the first piezoelectric actuator and the second piezoelectric actuator, and a main body portion that forms a space together with the plate portion. 可聴帯域を超える周波数帯域の音を発生させ、小型かつ軽量なスピーカ装置を提供する。可聴帯域の第１周波数信号を可聴音に変換する第１圧電アクチュエータと、可聴帯域よりも高い周波数帯域の第２周波数信号を高周波音に変換する第２圧電アクチュエータと、第１圧電アクチュエータおよび第２圧電アクチュエータが設けられた筐体部とを備える、スピーカ装置を提供する。筐体部は、第１圧電アクチュエータおよび第２圧電アクチュエータが設けられた板部と、板部と共に空間を形成する本体部とを有してよい。
