Abstract
Abstract A telephone loud-speaker system for use with telephones having a handset includes a chassis with a cradle for receiving the handset. The cradle is movable between a first position whereat the telephone's switch buttons are depressed, and a second position allowing the switch buttons to raise and actuate the telephone's electrical circuitry. Microphone, speaker and amplification devices permit use of the system without removing the handset from the cradle, without modification to telephone, and without requiring additional counter space.
