2. Description of the Related Art In a conventional mobile communication device, communication or warning voice is output to passengers in monaural.

[0003]

In a conventional mobile communication device, a voice such as a communication or an alarm is output in monaural. Therefore, in the case of voice communication, the sender is right when viewed from the receiver. To be on or to the left, or detect /
In the case of an alarm, it is not possible to directly perceive the positional relationship from the voice whether the target is on the right or left, and it is possible to separately check the outside of the aircraft by a display or visually and check the passenger's head. Inside, I had to establish correspondence between voice and position.
The present invention is intended to solve the above problems.

[0004]

In the stereo communication device of the present invention, a voice signal is input from a radio device that receives a radio wave transmitted by a fellow aircraft, a voice signal of a passenger is input from an in-flight communication device, and an alarm is issued from an alarm device. A voice input unit that inputs a voice signal of time and outputs a voice signal, an azimuth signal is input from a direction finder that receives a radio wave transmitted by the above-mentioned fellow aircraft, and an azimuth signal of a passenger is input from the voice input unit, and an alarm device The azimuth input section that inputs the azimuth signal of the alarm target and outputs the azimuth signal, and the left and right speakers that the listener uses by inputting the azimuth signal from the azimuth input section and the voice signal from the voice input section It is characterized by having a control / output unit for controlling the volume of each output voice.

[0005]

In the above, the radio wave transmitted by the wingman is received by the radio and the direction finder, the radio inputs the voice signal to the voice input section, and the direction finder outputs the azimuth signal indicating the direction of the radio wave to the azimuth input section. To enter.

The voice input section and the azimuth input section respectively input the voice signal and the azimuth signal to the control / output section, and the control / output section outputs the volume of the voice output by the left and right speakers used by the listener, respectively. It is assumed that the voice can be heard by the listener from the direction in which the wingman is present.

Further, the voice of the fellow passenger transmitted by the in-flight communication device is input to the voice input unit, and the signal indicating the position of the fellow passenger is input from the voice input unit which inputs the voice of the fellow passenger to the azimuth input unit. Then, the voice input unit and the azimuth input unit respectively input the voice signal and the azimuth signal to the control / output unit, and the control / output unit operates in the same manner as the case of the voice from the fellow aircraft.

Further, when the alarm device issues an alarm, a voice signal is input from the alarm device to the voice input section, and an azimuth signal indicating the direction in which the alarm object is present is input to the azimuth input section and the voice input is performed. Section and direction input section respectively input a voice signal and a direction signal to the control / output section, and the control / output section operates in the same manner as in the case of voice from a fellow aircraft.

According to the above, the voices from the fellow aircraft and passengers can be heard from the respective directions, and the voice from the alarm device can be heard from the direction in which the alarm target is present. Therefore, the listener is the speaker or the alarm target. Can be immediately known, and it becomes easy to understand the content of information and judge the situation.

Volume of the left speaker 9 and the right speaker 10 used by the listener 13 by inputting a direction signal from the same direction input unit 6 and a direction signal from the same direction input unit 6 and a voice signal from the voice input unit 5. And a control / output unit 7 for adjusting each of the above.

In the above, the radio wave from the wingman 1 is received by the wireless device 2 and becomes a voice signal, which is input to the voice input unit 5. Further, the radio wave is also received by the direction finder 3 and becomes an azimuth signal of the incoming radio wave, which is input to the azimuth input unit 6.

The voice input unit 5 and the azimuth input unit 6 respectively output a voice signal and a azimuth signal to the control / output unit 7, and the control / output unit 7 respectively outputs the azimuth signal input from the azimuth input unit 6. The audio signal output to the speakers 9 and 10 is adjusted so that the volume of the left speaker 9 is higher than that of the right speaker 10. Therefore, the listener 13 feels as if he / she hears a voice from the left side where the wingman 1 exists.

The radio wave received by the wireless device 2 is transmitted to the fellow device 4
In the case of the radio wave from, the control / output unit 7 increases the volume of the right speaker 10 based on the azimuth signal of the direction finder 3, so that the listener 13 feels as if he / she hears the sound from the right side.

The voice uttered by the passenger 14a is input to the voice input unit 5 through the microphone 8. The voice input unit 5 outputs a voice signal to the control / output unit 7, recognizes from which microphone the voice is input, and inputs the voice signal to the azimuth input unit 6.
