Abstract: The technology of this application relates to a multi-task network model-based communication method, apparatus, and system. The method may include a first communication apparatus processing an input signal by using a first backbone network model, to obtain a fusion feature, where the fusion feature is obtained by fusing a plurality of first features which are obtained by performing feature extraction on the input signal. The method may further include performing compression and channel coding on the fusion feature to obtain first information, and sending the first information to a second communication apparatus.

Abstract: The present disclosure provides an earphone and an earphone assembly. The earphone includes a housing, a bracket inside the housing, and a sound unit inside the housing. The housing has a first hole and a second hole. The bracket has a channel. The channel includes a slot section and a hole section. The section includes an opening, a first port and a second port. An inner wall of the housing blocks the opening, the first port is in connection with the first hole, and the second port is in connection with the second hole. The hole section has a first end in connection with the slot section and a second end in connection with the sound unit. The bracket is between the housing and the sound unit.
