Pelty is a very special Bluetooth speaker. It does not require any external power supply and can be regarded as a miniature thermal power generation speaker. A candle is placed inside the speaker, and the heat generated by burning the candle drives the built-in thermal generator to generate electrical energy, which converts heat energy into electrical energy. The speaker connects to the playback device via Bluetooth, and after lighting the candle for a few seconds, it can play beautiful music. As long as the candle remains lit, the speaker will continue to play. However, I think it is a flaw that this speaker does not have a built-in lithium battery for power storage. It can be used for boring fun, but it is not practical if it is really used for daily listening to music. The speaker is currently crowdfunding on the crowdfunding website indiegogo. Friends who are interested can check it out.
