Next we dig out the structure-borne speaker driver, previously seen in the P30 Pro teardown.

This little thing vibrates the display to create sound—replacing the traditional earpiece speaker we see in other phones. It's a nifty trick, but not without some downsides: it's an additional component to replace with the display, and if you crack your screen around the driver, you'll likely see a drop in sound fidelity.

Aaand what do we have here? It looks like the tiny circular LRA vibration motor from Mates past has been upgraded to a rectangular taptic engine-style buzzer.
