Description

technical field [0001] The invention relates to a broadcasting device, in particular to a bluetooth broadcasting device powered by solar energy. Background technique [0002] At present, a large number of broadcasting devices are installed in public places such as parks, squares, and some tourist attractions. They generally use a high-power power amplifier to drive multiple scattered speakers to regularly broadcast some information such as music, policies, regulations, and advertisements. . However, the construction cost is high, the energy consumption is high, and the interaction with the audience is not strong, and it is increasingly unable to keep up with the trend of the Internet age. With the maturity of solar distributed power generation technology, some technicians have developed MP3 players powered by solar energy. [0003] In the utility model patent with the application number of 201220565807.6, a solar MP3 player is disclosed, including a casing, a solar panel, ...
