The invention relates to an acoustic actuating device and an acoustic actuating device system. The sound of actuating device includes an actuating element, the actuating element includes a thin film piezoelectric element unit and one or more components with thin film having at least one piezoelectric element, the film component is fixedly stuck on the piezoelectric element, when the current is applied to the piezoelectric element when the thin film components of wave motion; support parts attached on the actuating element, to support the actuating element; the edge parts, and the actuating element. The acoustic actuating device system includes a first acoustic actuating device, and a second acoustic actuating device that is driven with the first acoustic actuating device. The actuating element is connected to the support member and the edge parts to improve the acoustic characteristics of low frequency, and the asymmetrical form connecting a plurality of piezoelectric element to improve the bandwidth of flatness, but also in a parallel arrangement of actuating elements to improve the sound.
