| anyone tried Vibration Speakers? Posted: 13 Aug 2011 01:36 AM PDT hi everyone, have you even heard about Vibration Speaker? i found them on a China wholesale site called: SpeMall.com, they're amazing! It seems a new electric product come from China, and It is a breakthrough which smashed the traditional speaker's limitation - Speakers with out trumpet. Ok, let's see how it works: you can put the vibration speaker on hard things like wood, metal, paperboard, glass or hollow wall. it will produce wonderful natural sounds by hitting these things, and let you enjoy the different music with different materials it touches. You can use it for iPhone, iPod or laptop PC. And these gadgets are with unique designs: really cute shape and small in size. very attractive. lol..but i think it would be perfect if they are wireless,or bluetooth or something. so, how do you think? |
