    Abstract: Various embodiment provide a multi-terminal cooperative working method, a terminal device, and a multi-terminal cooperative system. In those embodiments, a primary device can send networking information to a plurality of secondary devices, and the primary device has a permission to manage the cooperative network. The primary device can receive networking confirmation information sent by the plurality of secondary devices; and send configuration information to the plurality of secondary devices separately. The configuration information can be used to instruct to switch, based on a preset management permission switching mechanism when the primary device becomes abnormal or the primary device exits from the cooperative network, the permission to manage the cooperative network. The primary device can clear the secondary device from the cooperative network the secondary device becomes abnormal. In this way, robustness of the cooperative network can be improved.

    Abstract: The present invention discloses a sound processing method and apparatus. The method is applied to a non-video-call scenario. The method includes: when it is detected that a camera of a terminal is in a shooting state, collecting a sound signal by using the two microphones at the top of the terminal; calculating an interaural level difference between the two microphones based on collected sound signals according to a preset first algorithm; determining whether the interaural level difference meets a sound source direction determining condition; if the determining condition is met, determining, based on the interaural level difference, whether the sound signal includes a rear sound signal, where the rear sound signal is a sound signal whose sound source is located behind the camera; and if it is determined that the sound signal includes a rear sound signal, filtering out the rear sound signal from the sound signal.
