Yeah, I am trying to figure this out. It isn't an actual flower is it? The wording of the document makes it seem that way, but how ? lol Pretty neat though. Maybe I am just miss-interpreting the wording and the speakers are actually inside the bloom. Anyways, it'll make a neat decoration and people wont know where the flower is from
Here is another article Japan Gadget Turns Plants Into Speakers. "Place the flowers into the vase, turn on Ka-on and the magnet and coil relay the sound vibrations up the stems through the plant's water tubes." So the plant transmits the soundwaves
I think what it does is send the acoustic vibrations through that plant, and makes the plant, a "speaker."
