Abstract

An electronic device and a method for performing audio communication between a first space and a second space are provided. The electronic device is one of multiple near-end devices at the first space and serves as a master device, and at least one other near-end device serves as a slave device. A front-end processing circuit of the master device generates a master signal according to sound signals received by a microphone of the master device, and a front-end processing circuit of the slave device generates a slave signal according to sound signals received by a microphone of the slave device. An audio processing circuit of the master device generates a final signal according to the master signal and a slave signal, and the master device transmits the final signal to a far-end device at the second space via an internet connection.

Dependent claims

An electronic device for performing audio communication between a first space and a second space, wherein multiple near-end devices are located in the first space, at least one far-end device is located in the second space, the electronic device is one of the near-end devices, and the electronic device comprises:

a microphone, configured to receive sound signals emitted by a sound source located in the first space;
a front-end processing circuit, configured to generate an audio signal according to the sound signals received by the microphone;
and
an audio processing circuit, configured to generate a final audio signal according to the audio signal;
wherein when the electronic device is selected to be a master device, each of the other near-end devices is selected to be a slave device, the front-end processing circuit of the master device generates a master audio signal, the front-end processing circuit of the slave device generates a slave audio signal, the master device obtains the slave audio signal from the slave device via a transmission interface, and the audio processing circuit of the master device generates the final audio signal according to the master audio signal and the slave audio signal, to make the master device transmit the final audio signal to the at least one far-end device via an internet connection.
