Patent attributes
The utility model discloses a pattern projecting apparatus for automatically identifying and playing an audio. The projecting apparatus includes a first housing, a light-emitting assembly, a film assembly, an audio assembly, and an imaging assembly. The audio assembly includes a control board, an electronic label corresponding to a film sheet, an identifying module for identifying the electronic label and arranged on the control board, a storage medium pre-stored with an audio corresponding to a galactic starry sky pattern, and a speaker electrically connected to the control board. The electronic label is arranged on the film assembly. When the film assembly is mounted in a first mounting hole, the identifying module identifies the electronic label on the film sheet, positions the audio corresponding to the electronic label in the storage medium and plays the audio via the speaker, so that the galactic starry sky pattern projected by the projecting apparatus is played in combination with the audio. A user can hear an audio corresponding to a pattern of the film sheet when changing different film sheets. Therefore, the user's experience is effectively improved, and the practicability of the projecting apparatus is enhanced.
