Gadgets that turn any surface into a loudspeaker

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.
