What is the manufacturer of the internal speakers?

Hi @dhhsjshsh

I don't know who the manufacturer is as it is not specified in the Lenovo parts list for the laptop.

Click on Select Commodity > Internal speakers (1) to find the part number for the speakers.

The part number for the speakers is 5SB0S32041 (supplier examples only)

Here's the hardware maintenance manual for the laptop that may help.

The procedure to remove the speakers is on p.41 (47 of 66 pdf) of the manual so you can check if there's any information on the speakers themselves, but I somehow doubt that there will be anything except the part number perhaps.
