Phone's vibration when playing through speakers

[ykphuah]

This is the first time I am using front facing speakers phone, my previous phones all doesn't have this, so I am asking whether it is normal.

When I play a youtube video and use the speakers. From 60% volume, the phone vibrates, it is very easy to feel by just touching the back of the phone.

Is this normal?

Hi @ykphuah,

When you say it vibrates, is this the vibration of the phone like when you get a call or text, or is it from the pressure of speakers?

I think it is the vibration from the speakers, they stop when I pause the Youtube video.

@ykphuah,

I see what you mean. I have just tested this on my Xperia X and this is normal.
