Abstract
A sound identification device is provided. The sound identification device includes a microphone array and a processing unit. The microphone array includes a plurality of microphones disposed within a microphone module mounted on a housing of the sound identification device. Each microphone receives an acoustic signal caused by a gesture performed on a surface of the microphone module and converts the received acoustic signal to a digital acoustic signal. The processing unit is configured to receive the digital acoustic signal from each microphone, and perform a sound identification process on the digital acoustic signal from each microphone to generate a sound identification result conveying information of the gesture. The processing unit controls at least one application program executed by the processing unit according to the sound identification result.
