Hand held telephone set and audio processing method
First Claim
1. A handheld telephone set used by connecting an earphone, comprising:
- a telephone set main body unit;
detecting means for detecting which of a dual-ear mount type earphone and a single-ear mount type earphone is mounted to said telephone set main body unit;
an amplifier for amplifying an ambient sound and delivering said sound to said earphone; and
a control device for adjusting a signal level of said ambient sound output from said amplifier according to an output of said detecting means, wherein when said dual-ear mount type earphone is mounted to said telephone set main body unit a gain of said amplifier is increased to increase said signal level of said sound output from said amplifier, and when said single-ear mount type earphone is mounted to said telephone set main body unit said gain of said amplifier is reduced to decrease said signal level of said sound output from said amplifier.

Abstract
A handheld telephone set used by connecting a dual-ear mount type or single-ear mount type earphone that automatically sets an optimal signal level of an ambient sound according to the earphone type used, provided with: a telephone set main body unit, a detection device for detecting which type of earphone is mounted to the telephone set main body unit, an amplifier for amplifying the ambient sound to be delivered to the earphone, and a control device for controlling a signal level of the ambient sound output from the amplifier according to an output of the detection device. When either of these earphones is mounted, the control device controls the signal level of the ambient sound output from the amplifier to be fed back according to an output of the detection device.
