Embodiment 1

[0024] Embodiment 1: conference sound field communication with video.

[0025] The communication terminal is a communication terminal for a conference, and a plurality of earphones are externally connected to the communication terminal for a conference, and communication connections between the communication terminals are realized through a network. The communication terminal is connected with a sound field acquisition device, and the sound field acquisition device can be connected to the conference terminal through wireless methods such as Bluetooth, WIFI, WAPI, etc., or can be connected to the conference terminal through wired methods such as USB, RJ45, and TRS.

[0026] The communication terminal is correspondingly equipped with a sound field signal acquisition module, a sound field signal processing module and a sound field signal encoding and sending module, the signal input end of the sound field signal acquisition module is connected to the signal output end of the sound...

Embodiment 2

[0028] Embodiment 2: conference sound field communication without video.

[0029] like figure 2 As shown, in this embodiment, the conference terminal does not have a video acquisition device and a display device, and only implements conference sound field communication, and the working principle of the sound field communication is the same as that of Embodiment 1.

Embodiment 3

[0030] Embodiment 3: conference sound field communication in which sound field signals are collected through earphones.

[0031] like image 3 As shown, in this embodiment, the sound field acquisition device is a sound field microphone installed on the earphone, and the sound field information is collected through the sound field microphone on the earphone, and the rest of the working principle of the sound field communication is the same as in the second embodiment.

Description

technical field [0001] The invention relates to a communication device and a communication method capable of collecting sound field information. Background technique [0002] From the first generation of GSM mobile phones to the current 3G and 4G smart terminals, voice communication is basically narrow-band single-channel voice, and even this kind of voice experience has basically remained unchanged since Marconi invented the telephone, although the communication bandwidth has changed. Tens of thousands of times, the communication terminal has also developed from a simple voice terminal to an intelligent network that can take pictures, watch videos and surf the Internet, but the audio communication experience has never been substantially developed. With the development of communication technology, although conference communication systems and even video telepresence systems have appeared, the audio communication experience has not been substantially improved.
