Problems solved by technology
[0003] Especially in recent years, square dances have become more and more popular. Square dances are usually performed in outdoor public spaces, and there will be a lot of noise around them, and there are usually a large number of people in square dances. Therefore, the volume provided by generally small portable speakers is not enough, and a larger Only large speakers can meet the needs of square dancing, while larger speakers are more difficult to carry
The existing solution is generally to put the speaker on a small cart to pull it. Although this method solves the problem of moving the speaker, it is not necessarily flat in the outdoor environment. If it is not flat, the speaker is difficult to fix. It is also easy to fall over and cause damage when the speaker vibrates
In addition, when used outdoors, there is no power supply in some cases, and ordinary batteries cannot support long-term use.

The invention relates to a solar outdoor sound box, which comprises a box body and a power supply module, wherein a loudspeaker and a control circuit are arranged in the box body; the back of the box body is movably connected to a handle; a base with wheels is arranged at the bottom of the box body; the power supply module is electrically connected to the control circuit and comprises a solar panel and at least two storage batteries; the handle has two purposes, namely the handle is matched with the base with the wheels to pull the sound box and the handle can be used as a support frame when the handle overturns downwards, the structure is simple and the functions are variable; the power supply module comprises a plurality of storage batteries which are charged through solar power, the storage batteries can supply power to the loudspeaker by turns, and the setting is enough to cope with long-time outdoor use.
Description
technical field [0001] The invention relates to the field of audio, in particular to a solar outdoor sound box. Background technique [0002] The speaker is the terminal of the entire audio system, and its function is to convert audio power into corresponding sound energy and radiate it into the space. With the development of society, speakers need to be used in more and more occasions. [0003] Especially in recent years, square dances have become more and more popular. Square dances are usually performed in outdoor public spaces, and there will be a lot of noise around them, and there are usually a large number of people in square dances. Therefore, the volume provided by generally small portable speakers is not enough, and a larger Only large speakers can meet the needs of square dancing, while larger speakers are more difficult to carry. The existing solution is generally to put the speaker on a small cart to pull it. Although this method solves the problem of moving t...
