Help, I want to know what kind of transistor or mosfet this is.

I'm using a translator. Please understand.

My laptop fell to the ground, and the audio circuit parts fell off.

So I'm trying to replace the part, but I don't know exactly what it is.

It looks like a transistor or a mosfet.

Because the leg of the part is broken, I won't solder it with that part. Just tell me exactly what that part is.

These three-digit SMD markings are not very reliable to ID components. A quick search for a 751 sot-23 yields results for a zener diode, which this chip clearly isn’t. Why not instead try looking up reference designs for that audio IC? A lot of times the manufacturer just uses whatever circuit the IC manufacturer recommends.
