The present invention relates to a technology of amplifying an audio signal and automatically switching the output of the audio signal in a mobile device to which an ear-microphone set is connected. More specifically, the present invention relates to a technology of amplification and automated switching of the output of an audio signal based on the ear-microphone set, which is provided to amplify and output an external sound using the ear-microphone set used in association with to the mobile device through wired/wireless communications and output the amplified audio signal to an earphone or transmit the amplified audio signal to a device of the other party via a wireless network (for example, 3G, 4G, Wi-Fi, etc.). According to the present invention, amplification of an audio signal inputted through a microphone is added to a conventional hands-free talking function by using the microphone and the earphone embedded in the ear-microphone set for hands-free talking, which is used together with the mobile device. Therefore, the mobile device can be utilized as an audio amplifier (a hearing aid) when it is not used for talking on the phone. |
