iPhone 7 display vibrates considerably while playing music

Dear all,

Being honored to own an iPhone 7 now for a couple of days, I suffer an issue.

The display is considerably vibrating when music is played on the iPhone. And that does not need bursting loudness, but just less than a quarter of the maximum loudness and depends a bit on the track chosen.

In case you put your finger on the display then ( what you gonna do by just using your phone) you feel vibrations of the music on the screen.

Guess they're may utilize the iPhone's body as a kind of resonance space, but this was not a problem of my 6s (and 6, 5s), hence I think about a problem, asking kindly for your help / contribution before stepping into the ring with Apple's support.

Is anyone experiencing the same issue with the hardware?

Cheers.
