て行なわれ、時分割に送信、受信機能を働かせている。Conventional technology An alternating communication intercom consists of a transmitting/receiving speaker, a transmitting circuit that modulates the audio signal input from the speaker and outputs it to a signal line, and a receiving circuit that demodulates the signal from the signal line and converts it into an audio signal and outputs it to the speaker. . Switching between the transmitting and receiving functions is performed by the speaker pressing a changeover switch, and the transmitting and receiving functions are operated in a time-sharing manner.

がある。Problems that the invention aims to solve: In places like the bathroom, in order to switch between transmitting and receiving, you must touch the switch with wet or soapy hands, making it difficult to use the device. Therefore, it is necessary to switch between transmitting and receiving functions without touching the device.

なく。In order to transmit, when the speaker brings his/her mouth close to the transmitting/receiving speaker, it comes within the detection range of the human body detection circuit, and a detection signal is output.Also, when the speaker utters a voice, the volume detection circuit is detected, and a detection signal is output when the volume exceeds the set volume.Therefore, by emitting sound near the transmitting/receiving speaker for transmitting, the function switches from the receiving function to the transmitting function, so the speaker can without pressing a changeover switch.

きる。At the time of transmission, audio is collected by the transmitting/receiving speaker 1 and inputted to the transmitting circuit 3 as an audio signal. The audio signal input to the transmission circuit 3 is modulated and output to the signal line via the coupling circuit 5r. During reception, a signal is input to the receiving circuit 4 from the signal line via the coupling circuit 5. The input signal is demodulated and output as an audio signal to the transmitting/receiving speaker 1. The human body detection circuit 6 may use an infrared sensor or an ultrasonic sensor. The detection range of the human body detection circuit 6 is approximately 2 in front of the transmitting/receiving speaker 1 of the intercom 9 installed on the wall 8, as shown in the example shown in FIG.
The detection range is within 0CIn, and if the speaker approaches the transmitter/receiver speaker 1 to transmit, the detection range is 10.
shall be detected within. The volume detection circuit 7 outputs a detection signal when a peak value or an integral value per unit time of an audio signal inputted by a speaker or the like exceeds a preset value. The transmission/reception switching circuit 2 is normally connected to the receiving circuit 4 side, and when a detection signal is input from the human body detection circuit 6, the volume detection circuit 7
When a detection signal is input from , the connection is switched to the transmission circuit 3 side, and once switched to the transmission circuit 3 side,
The transmission circuit 3 until the detection signal from the human body detection circuit 6 stops.
Stay connected to the side. Therefore, by bringing the mouth close to the transmitting/receiving speaker 1 and emitting two sounds, the function is switched to the transmitting and talking functions, and when the user moves away, the function is switched to the receiving function, so there is no need to touch the device with wet hands or the like. Furthermore, since human body detection and volume detection are used simultaneously, it is possible to eliminate the drawback that the function switches to the transmitting function when the user approaches the transmitting/receiving speaker when the speaker is not transmitting.

触わらなくてす゛むので、機器の使用上好ましい。Effects of the Invention Since we have provided a human body detection circuit and a volume detection circuit whose detection range is in front of the transmitting/receiving speaker, the transmitting function can be activated by bringing your mouth close to the transmitting/receiving speaker and emitting sound, and the receiving function by moving your mouth away. You can switch to the snow function, eliminating the need to press the switch. Also, by using human body detection and sound 'ri detection in parallel, it was possible to prevent the function from switching to the transmitting function when the user approached the front of the transmitting/receiving speaker in a case other than transmitting. Furthermore, when using the device in a place such as a bathroom, it is preferable to use the device because there is no need to touch the device with wet hands.
