The speaker makes a wierd noise

Hi @fix_it2

The speaker has supposedly got an IPX7 waterproof rating i.e. it can be submerged up to 1 metre in water for 30 minutes, but this is when it left the factory and maybe the rating may not be so good anymore depending on how it has been handled since then, e.g. accidental knocks and bumps could create minute cracks in the seal for instance. Who knows.

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the speaker's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away

Maybe a bit late now but you can only try. Do not try to charge or to turn on your speaker and then remove the battery as soon as possible from the speaker to minimize any further damage.

Then you need to dis-assemble the rest of the speaker and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives which may leave residues and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better

Here is a link that describes the process. Electronics Water Damage

As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. The ends of any flex cables and their connectors need to be cleaned as well

Hopefully after you have done all this the speaker might possibly work correctly again.

Here is a link to a teardown video for the speaker that may help.

If this process seems too daunting, take your speaker to a reputable, professional electronics repair service, experienced in liquid damage repair and ask for a quote for a repair.
