Disassembling a unique Bluetooth speaker [Copy link]

 

 

I bought a Bluetooth speaker for five dollars, and it actually still works.

I listened to it and the sound quality is good.

Take it apart and see that the workmanship is pretty good.

There is a BAKEN (Shanghai Broadcom) BK3513 Bluetooth module inside;

A FM4158S 5W mono digital audio amplifier IC from FM (Fuman)

A MD25D80 8MB SPI FLASH suspected to be from GigaDevice.

There is also an AC1514CFA10E--BT chip, but I can't find the model number and I can't guess what it does.

I guess the hand soldering is charged by the point. I only soldered the pads that could be used for the Bluetooth module, and simply left the unused pads unsoldered.

Thanks, the trademark is indeed Jerry's, but I can't find the model number.

Really cheap

It’s already 5 dollars, what else do you want a motorcycle for? I just don’t know how long it can be used. The appearance is indeed unique, haha.

It's easy as long as you can find the manufacturer. Jie Li has a lot of re-marking.
