Abstract:
The present disclosure relates to a device for playing an acoustic sound and a touch sensation, and more particularly, to a device for emitting a sound to a front surface of a speaker and playing a touch sensation feedback to a rear surface of the speaker through a driving modulation using two or more speakers while simultaneously concentrating an acoustic pressure generated according to a vibration of a membrane of the speaker to a surface of a module through a movement pipe when an audio signal is applied.
