MICROPHONE, APPAREIL ÉLECTRONIQUE COMPRENANT UN MICROPHONE ET PROCÉDÉ DE COMMANDE D'UN APPAREIL ÉLECTRONIQUE

摘要

Various embodiments of the present invention relate to a microphone, an electronic apparatus including the microphone and a method for controlling the microphone, the electronic apparatus comprising: a substrate comprising a first hole and a second hole into which an audio signal is input; a case that has a resonance space formed thereinside as a first side thereof is opened, a second side thereof is closed, and the first side is coupled with the substrate; a first audio generation unit that converts an audio signal input through a first hole of the substrate into an electrical signal, and comprises a first plate and a first membrane spaced apart from each other; a second audio generation unit that converts an audio signal input through a second hole of the substrate into an electrical signal, and comprises a second plate and a second membrane spaced apart from each other; a sound insulation wall that is disposed between the first audio generation unit and the second audio generation unit, and separates spaces of the first audio generation unit and the second audio generation unit as a first side thereof is coupled with the case and the second side thereof is coupled with the substrate; a microphone that is electrically connected to the first audio generation unit and the second audio generation unit, and comprises a signal processing unit for removing a noise signal exceeding a threshold value by analyzing the audio signals transmitted through the first audio generation unit and the second audio generation unit; and a processor that is electrically coupled with the microphone, wherein the sensitivity of the first audio generation unit is configured to be lower than the sensitivity of the second audio generation unit, so that the microphone can correctly receive the user's audio command by removing noise greater than or equal to a predetermined level. Various embodiments other than the various embodiments disclosed in the present invention are possible.
