Seeed Super Directional Speaker Kit

Hello All, The vendor for this drop has let us know that due to an unexpected event out of his control he will not be able to fulfill any of the orders from this drop. Because of this we have decided to shut the drop down and apologize for any inconvenience this may have caused.

This would be an effective cell phone user's noise deterrent if used in conjunction with a directional microphone, beaming the offender's voice back at them with a brief delay. Makes it very difficult to concentrate/speak.

I've seen similar arrays used for acoustic levitation. Perhaps this would be neat to play with. I wouldn't use this as a listening source.
