The external device may be various devices which may receive the returned audio information and store and/or process the returned audio information, such as a computer, a tablet computer, a mobile phone, a server, other communication terminals and the like. The basic communication module 1006 transmits the returned audio information to the external device ED, such that the external device ED may store, process, transmit, or perform other operations on the returned audio information.
In one use scenario, with reference to
In the present disclosure, the basic communication module 1006 may communicate in a wireless manner.

The first sound reception unit 1004 may receive the broadcast stand-by audio information in a wireless manner.
In some embodiments, other devices paired with the communication terminal may perform an echo cancellation process on the acquired audio signal according to the stand-by audio information.
During an audio conference, the communication terminal or other sound reception apparatus at a first place may acquire the sound of users at the first place, or may also acquire the sound received from devices attending the audio conference at a second place and played by a loudspeaker at the first place. The sound at the second place is reproduced by the loudspeaker at the first place; the sound acquired by the sound reception apparatus at the first place is called as echo. Under the situation that the echo is generated, if the sound is transmitted to the second place without canceling, then the loudspeaker at the second place will reproduce the sound of the second place after a certain time, thereby causing inconvenience and trouble to the communication of users attending the conference. The users may communicate more smoothly by canceling the echo. The echo generally may be canceled according to an echo transmission characteristic; specifically, the echo is canceled by obtaining a corresponding echo feedback signal according to the signal played by the loudspeaker, and then using a filter to subtract the echo feedback signal from the acoustic signal acquired by the sound reception apparatus.

When the other communication terminals are not used to play the stand-by audio information, the stand-by audio information may be used as a reference signal for the echo cancellation process, so as to improve the quality of the second pickup audio information generated by the other communication terminals.
The steps S105 and the step S107 may be executed in a selected form, and may be simultaneously executed.
In some embodiments, before the step S130b, the method may include the step S120 as described above; and the step S120 include steps S121-S123 as described above, wherein the step S123 includes step S123b as follows:
Step S123b, performing an echo cancellation process on the second audio signal according to the stand-by audio information to acquire the second pickup audio information.
After the step S105 and the step S121, the second sound reception unit follows the preset rule or the input of the user to perform an echo cancellation process on the second audio signal acquired in the step S121 according to the stand-by audio information received from the basic communication module, and acquires the corresponding second pickup audio information according to the echo cancellation processing result. When the second sound reception unit does not include the loudspeaker, the second sound reception unit does not have played audio information as a reference signal for the echo cancellation process. After the basic communication module transmits the stand-by audio information to the second sound reception unit, the second sound reception unit may take the received stand-by audio information as the reference signal for the echo cancellation process to perform an echo cancellation process on the picked sound, thereby improving the quality of the second pickup audio information generated by the second sound reception unit.
In some embodiments, the step S110 may include steps S111-S113 as follows:
Step S111, picking up sound to generate first audio signal by the first sound reception unit.
The first sound reception unit picks up sound, and converts the acoustic signal into corresponding electrical signal to generate a first audio signal.
Step S113, performing an echo cancellation process on the first audio signal according to the stand-by audio information to acquire the first pickup audio information.
The basic communication module transmits the received stand-by audio information to the first sound reception unit in a wired or wireless manner. The first sound reception unit follows the preset rule or the input of the user to perform an echo cancellation process on the first audio signal acquired in the step S111 according to the received stand-by audio information, and acquires the corresponding first pickup audio information according to the echo cancellation processing result. When the first sound reception unit does not include the loudspeaker, the first sound reception unit does not have played audio information as a reference signal for the echo cancellation process. After the basic communication module transmits the stand-by audio information to the first sound reception unit, the first sound reception unit may take the received stand-by audio information as the reference signal for the echo cancellation process to perform an echo cancellation process on the picked sound, thereby improving the quality of the first pickup audio information generated by the first sound reception unit.
A person skilled in the art should understand that the audio information processing method does not have to strictly follow the above steps; the sequence of the above steps may be adjusted, a new step may be added or some of the steps may be deleted according to practical requirements, for example, the step S110 and the step S130 may be executed sequentially, or may also be executed at the same time.
A person skilled in the art may understand that all or some of the steps of the method for implementing the above embodiments may be completed by instructing relevant hardware via a program; the program is stored in a storage medium, and includes a plurality of instructions for instructing the corresponding device or processor in the communication terminal to execute all or some of the steps of the method provided in the embodiments of the present application. The foregoing storage media include: USB flash drive, removable hard disk, read-only memory (ROM), a random access memory (RAM), magnetic disk, optical disk, or other media that may store program code.
In the communication terminal, communication system and audio information processing method provided by the embodiments of the present disclosure, the communication terminal acquires the pickup audio information from a plurality of different sources, receives the returned audio information generated according to the pickup audio information from the plurality of sources, and transmits the returned audio information to the external device, thereby achieving the effect that when multiple people used, a plurality of sound reception devices or sound reception components may synchronously receive sound.
The descriptions above are only preferred embodiments of the present disclosure, but are not intended to limit the present disclosure. For a person skilled in the art, the present disclosure may have various changes and variations. Any modifications, equivalent substitutions, improvements and the like made within the spirit and principles of the present disclosure are all intended to be concluded in the protection scope of the present disclosure.
