A device includes a memory configured to store instructions. The device also includes a processor configured to execute the instructions to obtain spatial audio data representing audio from one or more sound sources. The processor is also configured to execute the instructions to generate first directional audio data based on the spatial audio data. The first directional audio data corresponds to a first arrangement of the one or more sound sources relative to an audio output device. The processor is further configured to generate second directional audio data based on the spatial audio data. The second directional audio data corresponds to a second arrangement of the one or more sound sources relative to the audio output device. The second arrangement is distinct from the first arrangement. The processor is also configured to generate an output stream based on the first directional audio data and the second directional audio data.

This application provides a decorating assembly, a housing assembly, and an electronic device. Gas flows between the outside of the electronic device, the first gap, the first channel, the breathable space, the waterproof breathable film, and the first space to implement a quick balance between internal air pressure of the first space and external air pressure of the electronic device. In addition, the waterproof breathable film is installed on the base, and the waterproof breathable film covers the breathable space, to ensure that when the decorating assembly is applied to the electronic device, the waterproof breathable film can prevent external liquid of the electronic device from entering the first space through the breathable space, thereby ensuring that the electronic device has relatively good waterproof performance.
