[0027] Please see Figures 1-3 This utility model provides a technical solution: a collectible card that can make sound, comprising:

[0028] The outer casing 1, located at the rear of the collectible card, is primarily used to connect accessories such as the speaker 8, enabling the collectible card to function. A cover plate 9, located on one side of the outer casing 1, seals the casing 1. The cover plate 9 connects to the collectible card on one side and houses the NFC coil 10. The NFC coil 10 can be placed against a mobile phone; the phone reads the information from the NFC coil 10 and displays the explanatory animation from the collectible card on its screen. The NFC coil 10 controls the speaker 8; while the explanatory animation appears, the speaker 8 plays audio matching the video. The outer casing 1 has a sound outlet 12 for better sound output from the speaker 8. A circuit board is provided on one side of the cover plate 9. The circuit board is used to connect the NFC coil 10, the battery 3, and the speaker 8 to ensure the transmission of electrical signals. The circuit board is equipped with a vibration sensor, which has the same function as the button 11 and can be used to drive the speaker 8 so that the speaker 8 can play audio. The position of the sound outlet 12 matches the installation position of the speaker 8 to ensure that the sound outlet 12 is directly facing the installation position of the speaker 8. The housing 1 is also equipped with a button 11, which drives the speaker 8 independently. The button 11 is used to control the drive of the speaker 8. The button 11 and the NFC coil 10 are electrically connected to the speaker 8 respectively to ensure that the button 11 and the NFC coil 10 can drive the speaker 8.

[0029] Battery 3, used to electrically drive speaker 8 and ensure that speaker 8 can produce sound, is located in housing 1. Housing 1 also has a battery compartment 4 for housing battery 3. The inner dimensions of battery compartment 4 match the outer dimensions of battery 3, so that battery compartment 4 will not move during installation. Battery compartment 4 is used to house battery 3, and a battery cover 2 is provided on the outside of battery compartment 4 to seal battery 3 and seal one side of battery compartment 4.

[0030] Magnet 6 serves as the basic adhesive for attaching the collectible card to other metal surfaces. It is located in the outer casing 1 to allow the outer casing 1 to adhere. The outer casing 1 also has a magnet compartment 5, which is used to house the magnet 6 and fix the magnet 6 in place, ensuring that the magnet 6 will not wobble during actual use. There is at least one magnet compartment 5, and the number of magnets 6 is the same as the number of magnet compartments 5. This design allows the collectible card to be magnetically attached more stably. The inner dimensions of the magnet compartment 5 match the outer dimensions of the magnet 6.

[0031] The speaker 8 is located in the housing 1. The speaker 8 is used to play audio explanations related to the contents of the collection card. The speaker 8 is connected to the battery 3 to ensure that the battery 3 can drive the speaker 8. The battery 3 drives the speaker 8. The housing 1 is also provided with a storage compartment 7. The speaker 8 is located in the storage compartment 7. The storage compartment 7 is connected to the battery compartment 4.

[0032] Example 1: NFC Triggered Audio Playback Mode

[0033] When a user brings an NFC-enabled phone close to the NFC coil 10 on the surface of the cover plate 9, the NFC coil 10 establishes a communication connection with the phone through electromagnetic induction, transmitting stored digital information such as cultural and creative content IDs and audio file indexes to the phone. Upon receiving the information, the phone calls its built-in application to parse the data and launch the corresponding animated display interface. Simultaneously, the electrical signal generated by the NFC coil 10 is transmitted to the drive circuit through an electrical connection with the speaker 8, activating the speaker 8. The battery 3 continuously supplies power to the speaker 8 through the connection structure between the battery compartment 4 and the mounting compartment 7, causing it to convert the electrical signal into mechanical vibrations and release audio through the sound outlet 12. During this process, the size-matching design of the battery compartment 4 ensures stable power supply to the battery 3, avoiding poor contact; the magnet 6 inside the magnet compartment 5 maintains the overall position of the device by adhering to metal surfaces such as refrigerator doors, achieving an immersive experience with synchronized animation and audio.

[0034] Example 2: Manually triggering audio playback mode

[0035] When the user presses button 11 on the surface of the outer casing 1, the conductive contacts inside button 11 close, forming a complete current loop. This loop directly connects battery 3 and speaker 8, allowing the electrical energy from battery 3 to be instantly transferred to the driver unit of speaker 8. Driven by electrical energy, the voice coil of speaker 8 drives the diaphragm to reciprocate, generating mechanical vibrations corresponding to the preset audio file. The vibrations propagate through the air medium and are released directionally through the sound outlet 12 to form audible sound waves. During this process, the sealing structure of battery cover 2 on battery compartment 4 prevents battery 3 from becoming loose, ensuring power supply stability; the cooperation between magnet compartment 5 and magnet 6 ensures that the device remains in an attracted state during operation, avoiding displacement due to external forces that would affect the user experience.

[0036] Example 3: Composite Functional Collaborative Working Mode

[0037] When the collectible card is in standby mode, magnet 6 is continuously attracted to the metal surface through the fixing structure of magnet compartment 5, while NFC coil 10 maintains a low-power standby mode, monitoring surrounding NFC signals in real time. When the user approaches and holds the phone close to NFC coil 10, the NFC communication process as described in Example 1 is triggered, the phone displays animated content, and the speaker 8 is activated through NFC coil 10. If the user wishes to repeat audio or adjust the volume at this time, they can directly press button 11. The independent control circuit of button 11 will take over the drive signal of speaker 8 first, realizing manual intervention. In this composite mode, the connection design between battery compartment 4 and housing compartment 7 optimizes the internal space layout and reduces line loss; the sealed connection between cover 9 and outer shell 1 effectively prevents dust and moisture intrusion, ensuring the long-term stable operation of NFC coil 10 and speaker 8.

[0038] Example 4: Vibration-triggered audio playback mode

[0039] When the user taps the collectible card, or attaches it to a refrigerator or other object using the magnet 6, the vibration sensor in the cover plate 9 is triggered when the collectible card is vibrated. This triggers the speaker 8 via the circuit board in the cover plate 9, which then releases audible sound waves through the sound outlet 12, allowing the user to receive audio information.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
