Therefore, when the projection of the target projection pattern piece is successful, the corresponding audio can be sounded, and the atmosphere can be better set off.
Here, the multimedia system stores a mapping table between each projection pattern piece and an audio in advance, the mapping table stores a corresponding relationship between each projection pattern piece and the audio, and the audio may be pre-recorded voices (spoken words, blessing words, etc.), or songs, background music, etc.
For example, the projection pattern pieces and the audios may be numbered separately, and the number of the projection pattern pieces may be: 1. 2, 3, etc.; the audio number may be: A. b, C, etc.; then 1 corresponds to a, 2 corresponds to B, and 3 corresponds to C in the mapping table; and so on.

When the target projection pattern piece is thrown to the projection area, the corresponding audio sounds in a linkage mode.
Correspondingly, in other scenes, such as a birthday blessing scene, the user can switch to the projection pattern sheet corresponding to the birthday blessing scene, so that atmosphere creation under different situations is realized.
