With this item, anything can vibrate into a speaker. Plug the vibration speaker's 3,5mm jack into your music device and stick the vibration pad (sticker) onto virtually any surface/object. Different objects produce a different sound effect. Compatible with iPods, computers and any mobile phone or device with a 3.5mm mini jack. The vibration pad is reusable. When it's dirty, just wipe with a damp cloth and its stickiness should be restored once it's dry.
