Description

Technical field:

[0001] The utility model relates to the technical field of sound boxes, in particular to a sound box control circuit with lighting and sleep-aiding functions. Background technology:

[0002] Speakers are important audio output devices and are very common in our daily lives. In the early days, speakers were mainly made of wood, which provided good resonance characteristics and sound quality. With the progress of industrialization, new materials such as plastics and metals were gradually applied to speaker design, making speakers lighter, stronger and easier to produce.

[0003] At the same time, the shape and size of speakers have also changed. From the initial large vertical speakers to bookshelf speakers, floor-standing speakers, and now popular small portable speakers and bone conduction speakers, the design of speakers has gradually developed towards diversification and personalization. Modern speakers not only focus on the performance of sound, but also emphasize the integration with the home environment and the satisfaction of personal aesthetics.

[0004] Nowadays, with the improvement of living standards, users' demands for speakers are not only to provide high-quality sound quality, but also to meet certain specific functions, bringing more convenience and fun to users' lives. For example, when using them at night, users often need to use the lighting function and the sleep-aiding function. However, the existing speakers on the market can generally play Bluetooth audio sources, but do not have lighting and sleep-aiding functions, which is not convenient for users to use at night.

Due to the use of the voltage conversion module, the mobile speaker control circuit can use a higher charging voltage, improve charging efficiency, reduce charging time, and improve user experience.
