How to increase speaker volume?

Question

Android

Hello. Perhaps not a typical question, but suddenly someone came across a similar one. There is a non-named Chinese portable bluetooth speaker that also supports radio and playback from a flash drive. But there is a strange bug, from phones, the sound in the column at full volume is barely audible ... While the radio, from a flash drive, or from a computer, the sound is very loud, you can not hear your speech. What could be the problem? I don’t want to break the column and add an amplifier to the circuit ...
