Description

Technical Field

[0001] This utility model belongs to the field of entertainment equipment technology, and in particular relates to a circuit for a physical product circuit used to unlock digital albums. Background Technology

[0002] In recent years, due to rapid technological advancements and the increasing prevalence of playback devices such as smart mobile devices, the traditional method of purchasing physical music albums has gradually declined. It has been replaced by purchasing music online, with users downloading music onto their smart mobile devices or tablets. Online digital music download services have also flourished with the widespread adoption of mobile smart devices. Currently, there are also platforms that upload music for the general public to purchase and download.

[0003] While downloading music is convenient, it reduces face-to-face interaction between fans and artists. To enhance the interaction between singers (or artists) and their fans (or moviegoers), record companies typically develop media promotion plans, using various methods (such as radio, print, television, concerts, or other projects (such as advertising shoots)) to promote the album or add creative touches to upcoming album releases (such as album packaging). However, due to the album's potential inconvenience in use and portability, or the lack of surprise from fans with the creative ideas, the interactive effect is often limited.

[0004] A new album product is proposed, which has the function of outputting a data key to unlock the corresponding album library on a mobile device. Utility Model Content

Figure 1 , Figure 2 , Figure 3 As shown, the circuit for unlocking a digital album provided in this embodiment includes a main control circuit, a power control circuit, a speaker control circuit, and a power supply. The first control output terminal of the main control circuit is electrically connected to the control terminal of the power control circuit, and the second control output terminal of the main control circuit is electrically connected to the control terminal of the speaker control circuit. The power supply provides power to the power control circuit, the speaker control circuit, and the main control circuit.

[0024] It should also be noted that when the main control circuit controls the speaker control circuit to output activation music, the activation music corresponds one-to-one with the key data stream. When the mobile device receives both the key data stream and the activation music at the same time, it can unlock the corresponding album library.

[0025] Working principle: Pressing switch K1 turns on transistor Q2, which in turn turns on MOSFET M1, allowing the battery to start supplying power. After the main control circuit is powered on, it outputs a POW_EN signal to keep transistor Q2 and MOSFET M1 conducting, ensuring continuous battery power. When the device is activated, the product outputs a key data stream. Based on this key data stream, the speaker control circuit outputs the corresponding activation music. The key data stream is then transmitted wirelessly to the mobile device. The mobile device software can then access the corresponding album database based on the key data stream and the activation music, allowing the mobile device to access the content of that album database.
