Abstract
A hands-free device and method are provided for implementing a hands-free function to a radio terminal. The hands-free device includes an amplifier for amplifying voice signals received from a microphone; a switching unit for switching the amplified voice signals to a speaker or to an earphone terminal; a controller for controlling the amplifier to amplify the voice signals received from the microphone by a predetermined value and for controlling the switching unit to output the amplified voice signals via the earphone terminal if the controller determines that the hands-free function has been selected; and an external voice output unit having an input terminal connected to the earphone terminal for receiving the amplified voice signals and a voice output speaker for outputting the amplified voice signals. The method for implementing a hands-free function to the radio terminal includes the steps of checking whether the hands-free function has been selected; controlling the switching unit to switch the amplified voice signals to the earphone terminal if the hands-free function has been selected; and outputting the amplified voice signals through the earphone terminal. The method further includes the steps of receiving voice signals through the microphone; and controlling the amplifier to amplify the voice signals received through the microphone by a predetermined value.
