A sound receiving/broadcasting system, comprising a master device and a plurality of slave sound receiving/broadcasting devices,
- wherein the master device comprises:
- an audio input/output interface, which is arranged to generate a first audio input signal from a first input sound received from an external device or to transmit a third audio output signal to the external device;
- a first audio signal processing circuit, which is in electrical connection with the audio input/output interface, wherein the first audio signal processing circuit comprises an audio mixer circuit;
- a first controller, which is in electrical connection with the first audio signal processing circuit;
- and
- a plurality of first communication interfaces, each of the first communication interface being in electrical connection with the first controller and the first audio signal processing circuit;
- wherein each of the slave sound receiving/broadcasting devices comprises:
- a sound input device, which is operable to receive a second input sound and generate a second audio input signal;
- a sound output device;
- a second audio signal processing circuit, the second audio signal processing circuit being in electrical connection with the sound input device and the sound output device;
- a second controller, which is in electrical connection with the second audio signal processing circuit;
- and a second communication interface, which is in electrical connection with the second controller;
- wherein each of the first communication interfaces of the master device is paired with and in wireless communication connection with the second communication interface of a different one of the slave sound receiving/broadcasting devices;
- wherein the master device, in response to receiving the first audio input signal, transmits separately a first transmission signal to each of the slave sound receiving/broadcasting devices according to the first audio input signal, and all of the slave sound receiving/broadcasting devices make the sound output device of each of the slave sound receiving/broadcasting devices outputting a corresponding first output sound according to the first transmission signal received thereby;
- wherein when the sound input device of one of the slave sound receiving/broadcasting devices receives the second input sound and generates the second audio input signal, the one of the slave sound receiving/broadcasting devices that generates the second audio input signal transmits, according to the second audio input signal, a second transmission signal to the master device, and the master device transmits separately a third transmission signal to each of the slave sound receiving/broadcasting devices according to the second transmission signal received thereby, and all of the slave sound receiving/broadcasting devices make the sound output device of each of the slave sound receiving/broadcasting devices outputting a corresponding second output sound according to the third transmission signal received thereby;
- and
- wherein each of the slave sound receiving/broadcasting devices is arranged to be switchable between a sound-inputting mode and a non-sound-inputting mode, and the sound receiving/broadcasting system is arranged to allow only a limited number of the slave sound receiving/broadcasting devices to be simultaneously set in the sound-inputting mode, and each of the slave sound receiving/broadcasting devices that is not in the sound-inputting mode is set in the non-sound-inputting mode, wherein
- when the slave sound receiving/broadcasting devices are in the sound-inputting mode, the sound input devices of the slave sound receiving/broadcasting devices are operable to receive the second input sound and generate the second audio input signal, and the sound output devices of all of the slave sound receiving/broadcasting devices separately output the corresponding second output sounds according to the second audio input signal;
- and
- when the slave sound receiving/broadcasting devices are in the non-sound-inputting mode, the sound input devices of the slave sound receiving/broadcasting devices do not generate the second audio input signal.
