Abstract:
1. A method for controlling a speaker volume of a speaker phone, comprising: sensing whether or not there is a user's contact with a specific portion of the speaker phone, by using a contact sensing unit located on the specific portion of the speaker phone which contacts a face or an ear of the user when the user places the speaker phone to their ear; and controlling a speaker volume of the speaker phone according to the contact sensing result from the contact sensing unit, wherein if the sensing step determines that a user's contact with the contact sensing unit exists, the controlling step automatically adjusts the speaker volume of the speaker phone from an initial volume level to a normal volume level lower than the initial volume level without the user manually adjusting the speaker volume, wherein if the sensing step determines that a user's contact with the contact sensing unit does not exist, the controlling step automatically adjusts the speaker volume of the speaker phone back to the initial volume level, and wherein the sensing step senses whether or not there is the user's contact with a push-to-talk (PTT) button of the speaker phone by using the contact sensing unit attached to the PTT button.
