Document Type and Number:
WIPO Patent Application WO/2020/130590
Kind Code:
A1
Abstract:
An audio device according to an embodiment set forth in the present document comprises: a housing comprising a first surface, a second surface that faces the first surface, and side surfaces that surround the space between the first surface and the second surface; a vibration element disposed on the first surface; a microphone which acquires sound generated by the vibration of an external object by the vibration element; a printed circuit board disposed inside the housing; a processor disposed on the printed circuit board; and a communication circuit which is electrically connected to the processor, and receives a first audio signal from an external electronic device, wherein the processor, when the vibration element is attached to an external object, generates a second audio signal such that the vibration element vibrates the external object, causes the microphone to acquire a third audio signal generated by the vibration of the external object, corrects the first audio signal on the basis of the deviation between the second audio signal and the third audio signal, and can make the vibration element vibrate the external object on the basis of the corrected first audio signal. Various other embodiments inferred from the specification are also possible.
