Placement issue

The media could not be loaded. Why is the speaker wobbly? It makes me really irritating.But other than that it is a very fine speaker. The sound is amazing, battery backup is awesome, instantly connects via Bluetooth. No doubt about it, that's why I bought it. But this wobbly thing is making me pull my hair
