PROBLEM TO BE SOLVED: To provide a loudspeaker system which can receive the message from a visitor by automatically dealing with the visitor and, in addition, can make busy recording. SOLUTION: In this loudspeaker system, a slave door-phone 1 installed outdoors (for example, to the entrance of a house, etc.), is connected to a master interphone device 2 installed indoors through a communication line 3. The interphone device 2 is provided with a response message transmitting section 27 which transmits a preregistered response message to a transmitting channel- side signal route in response to a call from the door-phone 1 side, and a voice recording and reproducing section 26 which records voice signals inputted from the door-phone 1 side in response to the response message from the transmitting section 27 and voice signals inputted from both the door-phone 1 and interphone device 2 during speaking and, at the same time, outputs the recorded voice signals to a receiving channel-side signal route.
