Abstract
A speaker module of a portable terminal and a method of execution of a speakerphone mode using the same are provided. The speaker module includes a nondirectional microphone, a directional microphone, at least one speaker, and a controller. The nondirectional microphone is applied to one side of the portable terminal. The directional microphone is applied to another side of the portable terminal. The at least one speaker is installed in the same direction near the directional microphone. When the portable terminal is in a speakerphone mode, the controller controls to detect voice signal levels and/or frequency characteristics input to the two microphones, sets a transmission/reception mode of the portable terminal, and mute-processes a corresponding microphone.
Claims13
A speaker module of a portable terminal, the speaker module comprising:
- a nondirectional microphone applied to one side of the portable terminal;
- a directional microphone applied to a side opposite to the one side of the portable terminal to which the nondirectional microphone is applied;
- at least one speaker installed adjacent to the directional microphone on the same side to which the directional microphone is applied;
- and
- a controller for, when the portable terminal is in a speakerphone mode, controlling to detect at least one of voice signal levels and frequency characteristics input to the two microphones, to set a transmission or reception mode of the portable terminal, and to mute-process the corresponding microphone.
A method of execution of a speakerphone mode of a portable terminal comprising a nondirectional microphone applied to one side of the portable terminal, a directional microphone applied to a side opposite to the one side of the portable terminal to which the nondirectional microphone is applied, at least one speaker installed adjacent to the directional microphone on the same side to which the directional microphone is applied, and a controller for controlling the two microphones based on a transmission or reception state when the portable terminal is in a speakerphone mode, the method comprising:
- when the portable terminal is in the speakerphone mode, determining if the nondirectional microphone and the directional microphone simultaneously recognize a receiving voice signal level;
- and
- when the two microphones simultaneously recognize the receiving voice signal level, mute-processing the two microphones and enabling only the speaker.
A portable terminal, comprising:
- a nondirectional microphone applied to one side of the portable terminal;
- a directional microphone applied to a side opposite to the one side of the portable terminal to which the nondirectional microphone is applied;
- at least one speaker installed adjacent to the directional microphone on the same side to which the directional microphone is applied;
- and
- a controller for, when the portable terminal is in a speakerphone mode, controlling to detect at least one of voice signal levels and frequency characteristics input to the two microphones, to set a transmission or reception mode of the portable terminal, and to mute-process the corresponding microphone.
