411 allows the driving gear 32 to move along a preset path, to simplify the installation operation of the film disc 40 and enhance the user experience and the practicality of the device.

Further, as shown in FIG. 1 to FIG. 6, the projector further includes an audio assembly housed within the body 10 and an electronic tag 43 installed on the film disc 40 and electrically connected to the audio assembly; and the audio assembly includes a control panel 51, an identification module 52 for identifying the electronic tag 43, a storage medium pre-stored with audio corresponding to the electronic tag 43, and a speaker 54 electrically connected to the control panel 51. In this embodiment, the audio assembly is configured to identify the electronic tag 43, and play corresponding audio content based on information stored in the electronic tag 43. The storage content of electronic tag 43 corresponds to content of the patterns on the film, allowing the projector to simultaneously output sound effects or narrations that match the image when the projector displays the image. The design not only enhances an immersive projection effect but also helps the user understand the projected content more intuitively, to improve the interactivity and practicality of the projector. In addition, through an automatic identification function of the electronic tag 43, the projector can automatically load the corresponding audio content based on different film discs 40, to avoid cumbersome operations of manual audio selection by the user, making the projector convenient to use.

Further, the identification module 52 is configured to detect and read the information in the electronic tag 43, and transmit the retrieved information to the control panel 51. The control panel 51 parses the information from the electronic tag 43 and extracts audio data corresponding to the electronic tag 43 from the storage medium. Then, the control panel 51 controls the speaker 54 to play the corresponding audio content, allowing the projector to simultaneously output the sound effects or the narrations that match the film patterns. The design ensures the accuracy and automation of audio playback, and improves the user's viewing experience. In addition, the storage medium can pre-store a plurality of sets of audio data for different film discs 40 to meet the needs of various projection content, to further improve the practicality and interactivity of the projector.

In addition, the rotating disc 42 is further provided with a reset mark, and the body 10 is provided with an identification module 52 for identifying the reset mark. The identification module 52 is electrically connected to the control panel 51, and the drive assembly is electrically connected to the control panel 51, so that when the identification module 52 identifies the reset mark, the control panel controls the drive assembly to drive the rotating disc 42 to rotate to an initial position of the film patterns.

Further, as shown in FIG. 1 to FIG. 6, an inner wall of the body 10 is provided with a mounting shell 60 corresponding to the insertion slot 11, and the film disc 40 passes through the insertion slot 11 and is installed in the mounting shell 60; and the mounting shell 60 is provided with at least one spring clip 62, where the spring clip 62 abuts movably against the outer wall of the film disc 40. In this embodiment, the mounting shell 60 is fixed to the inner wall of the housing 41 and is located corresponding to the insertion slot 11, to ensure that the film disc 40 can be stably and precisely installed within the body 10.

The spring clip 62 is configured to secure the film disc 40. Specifically, the spring clip 62 is disposed on the inner wall of the mounting shell 60 and partially protrudes onto the interior of the mounting shell 60. When the film disc 40 is inserted into the mounting shell 60, the spring clip 62 provides continuous pressing forces through the elastic action, to effectively prevent the film disc 40 from loosening or shifting during use, ensure that the film disc 40 remains in a stable position within the projector, and avoid instability or image displacement caused by vibration or external forces.

There may be a plurality of spring clips 62, to provide greater pressing forces for the film disc 40.

Further, as shown in FIG. 1, a side wall of the body 10 is further provided with a plurality of storage slots 13 for storing the film disc 40. In this embodiment, the design of the storage slot 13 allows the user to easily store a plurality of film discs 40, and each storage slot 13 is of an appropriate size to ensure that the film disc 40 can be securely placed without easily sliding or falling off. The number and position of the storage slots 13 have been carefully set to facilitate the user in quickly taking and placing different film discs 40, to improve the practicality and convenience of the device.

Further, as shown in FIG. 1 to FIG. 5, the body 10 further includes a handle 15, the outer wall of the body 10 is provided with a movable slot 16, and the handle 15 is movably installed in the movable slot 16. In this embodiment, the design of the handle 15 allows the user to adjust the position of the handle 15 as needed, providing a convenient carrying method while also allowing the handle 15 to be stored within the movable slot 16 when not in use, to avoid occupying excessive space. The setting of the movable slot 16 ensures the stability of the handle 15 and can prevent the handle 15 from accidentally falling off or shifting during use. The design increases the product's portability and enhances safety and stability during use.

Further, as shown in FIG. 1 to FIG. 5, the body 10 further includes a triggering mechanism, the triggering mechanism includes a push rod 72 and a lift rod 71, the body 10 is provided with a mounting hole, the mounting shell 60 is provided with a movable hole, the lift rod 71 passes through the movable hole and abuts against the film disc 40, one end of the lift rod 71 close to the push rod 72 is provided with a movable roller 714, the push rod 72 passes through the mounting hole, one end of the push rod 72 close to the movable roller 714 is provided with an abutment block 721, and the abutment block 721 is inclined on a side that abuts against the movable roller 714. In this embodiment, the triggering mechanism is used for automatically releasing or pushing the film disc 40 when the user needs to replace or adjust the film disc 40. Specifically, the push rod 72 pushes the lift rod 71, causing the movable roller 714 on the lift rod 71 to come into contact with the film disc 40, to enable the film disc 40 to be pushed outward or released under the action of the push rod 72. The inclined design of the abutment block
