Apparatus and method for outputting sound in mobile terminal
First Claim
1. A sound output apparatus, comprising:
- a modem chip comprising a first amplifier configured to amplify and transfer an electric signal to a switch;
the switch configured to selectively connect an output line of the first amplifier to a receiver or a second amplifier;
the second amplifier connected with the receiver and the switch, and configured to amplify and transfer the electric signal received from the first amplifier to the receiver when the switch connects the output line of the first amplifier to the second amplifier; and
the receiver configured to output the electric signal received from the first amplifier or the second amplifier.

Abstract
An apparatus and method for outputting a sound with Hearing Aids Compatibility (HAC) in a mobile terminal. The sound output apparatus includes a modem chip including a first amplifier amplifying and transferring an electric signal to a switch, a switch that selectively connects an output line of the first amplifier to a receiver or a second amplifier, a second amplifier connected with the receiver and the switch and that amplifies and transfers an electric signal received from the first amplifier to the receiver when the switch connects the output line of the first amplifier to the second amplifier, and a receiver connected with the switch and the second amplifier and that converts and outputs an electric signal received from the first amplifier or the second amplifier into a sound. This allows for the stable transfer of a sound to hearing handicapped persons with HAC without distortion of the sound quality.
