Transform tables, floors, windows even car roofs into
loudspeakers. IT’s called Eishock and
costs 45$ and has enough battery power to play music for six to eight hours.
With a standard audio jack can connect to a smartphone or other music sources.
It’s got a frequency response of 50 Hz to 18 kHz but don’t expect that the
performance to carry over if you’re attaching it to a folding table.
A similar device is produced by Vu-lion, with a smaller
3-watt UL-U100, but comes with a Bluetooth connection for wireless music
transmission. This one costs around 20$ but you have to buy them in bulk (1000)
More powerful is the cowin’s nanobeat, witch for a price of
around 78$ come with a Bluetooth model and a 65$ comes with a model that plays
music stored on a micro SD card. It’s suitable for short flat surfaces, Cowin
produces even a model that can be attached to a window with a suction cup.
