Description

Voice communication system

The present invention relates to a voice communication system that transmits and receives voice between a parent device and a child device by wireless communication.

Generally, a wireless device called an intercom transmits and receives audio signals between a parent device connected by wire to the main device and a child device connected wirelessly to the parent device. One of these types of wireless devices is known to have a one-channel communication line. In this type of wireless device, since there is only one line of communication between the child device and the parent device, the child device can receive only one type of voice sent from the main device. For example, the slave unit cannot receive the voices of a plurality of groups at the same time, and cannot adjust the sound and the music flowing in the background separately to the desired volume at the slave unit.

The command generator 26 determines the contents of the combination when the operation button 25 is pressed, and generates a command that instructs the main device 3 how to process the call data based on the determination result. . The output side of the command generation unit 26 is connected to the transmission / reception unit 27, and the generated command is transmitted / received to / from the main apparatus 3 from the transmission / reception unit 27 via the parent device 1.

The transmission / reception unit 27 also transmits / receives call data between the child device 2 and the parent device 1, but the configuration of the portion is the same as that of the conventional parent device 1 and the child device 2, and thus the description thereof is omitted. By superimposing the call data and the command on the transmission wave, the call data and the command can be simultaneously transmitted using one line established between the parent device 1 and the child device 2. When a plurality of slave units 2 are used, the master unit 1 and each slave unit 2 use different channels, so that there is one line between the master unit 1 and each slave unit 2. The master unit 1 can simultaneously transmit and receive call data and commands having different contents with each slave unit 2 by using a plurality of lines.

For example, a certain command indicates an instruction content for increasing or decreasing the volume level of the call data transmitted from the main device 3 to the child device 2. In addition, the other command indicates an instruction content for changing the mixing ratio in the case of call data in which a plurality of voice data is mixed or call data in which voice data and music data are mixed.

In this case, by operating the operation button 25 and the volume button 22 in combination, it is also possible to set the volume and the degree of mixing of the audio data and music data selected by the operation button 25. When processing different types of audio data and music data, a plurality of volume buttons 22 can be provided, and different audio data and music data can be assigned to each volume button 22.

The command generated by the command generation unit 26 is transmitted to the transmission / reception unit 33 of the main device 3 via the transmission / reception unit 27 of the child device 2 and the parent device 1. When the slave unit 2 is in the standby state, when the operation button 25 or the volume button 22 is operated to complete the command generation, for example, one of the three operation buttons 25 shown in FIG. 1 is set. When the setting button is pressed, a command is transmitted by opening the line between the slave unit 2 and the master unit 1. When the handset 2 is in a call state with the base unit 1, the generated command is transmitted to the base unit 1 by being superimposed on the call data or interrupted. It should be noted that by providing the volume button 22 with the functions of the operation button 25 and the setting button, the volume setting command can be transmitted to the parent device 1 only by operating the volume button 22.

The main device 3 that has received the command changes the set value of the level control unit 32a or the mixing unit 32b based on the instruction content of the command. Thereby, the output level of the call data transmitted to the handset 2 or the mixing ratio of the voice data and / or music data input to the main device 3 is changed. Thereafter, when voice data and / or music data is input from the other handset 2 or the sound source to the main device 3, the call data is received according to the level and mixing ratio set by the command from the handset 2 on the receiving side. Generated. The generated call data is transmitted to the receiving side slave unit 2 via the transmission / reception unit 33 of the main device 3 and the master unit 1.

In particular, since all processing such as mixing ratio and volume adjustment is performed by the main device 3, it is not necessary to provide call data processing hardware and software in each slave unit 2, and the configuration of the slave unit 2 becomes complicated. There is nothing.

(B) Since the contents of the processing performed by the call data processing unit 32 are associated with a combination of one or a plurality of operation buttons 25 in advance, a command required by simply pressing the operation button 25 is given to the main device 3. Can be sent. Therefore, even a small handset 2 that does not have general-purpose input means such as a keyboard can transmit without requiring a command error operation.

(C) By adjusting the mixing ratio of different types of sound sources such as audio data and music data, it becomes possible for the receiving side handset 2 to receive the call data that is most easily heard. Even in a system having an intercom mode in which audio data from a plurality of slave units 2 are mixed and transmitted to the slave unit 2 on the reception side, only the voice of the specific slave unit 2 on the transmission side is emphasized and received It is also possible to do.

(D) In the case where a plurality of slave units 2 are provided, it becomes possible to receive call data in which different mixing ratios and volume adjustments are made according to the user's request for each slave unit 2, so that a call for each user can be received. It is possible to obtain appropriate call data according to the data reception environment.
