Strange sounds from Smart Lock Touch Wifi

My smart lock makes a weird buzz/whine when it plays the lock or unlock chime. I posted about it on Reddit and others said their locks did not make this noise, so I got a replacement lock today from Best Buy. The new one does the same thing.

Anyone else hear this from theirs? It is not from the mechanics of the lock - if I disable the lock/unlock chimes, the sound goes away.

That sound is from the speaker…

Yes, I know it is coming from the speaker. I just don’t know if it’s normal to hear that whine or buzz at the same time as the chime is playing.

It is not a normal noise so my guess is the speaker is bad or going contact
