To fully integrate sound into Wearable Electronic products like bags and backpacks the first and only choice is using NXT flat panel speaker technology.

 Only this flat panel speaker technology allows the seamless, invisible almost magical effect that allows the bags 'native' material to be transformed into a loud speaker.

 Those are the two elements that enable this magic: NXT's core technology, the so called Exciter or Transducer. When this exciter is glued on plastic, glass fiber, carbon fiber, aluminum or any number of stiff, lightweight substrates. The sound is generated be exciting the material on which the exciter is mounted on. The simplest form is to glue one of those exciter on a window glass pane and the whole window would be a loudspeaker.

 The second element for building the soft goods sound magic is EVA (Polyethylene vinyl acetate) which is also known as 'expanded rubber' or 'foam rubber'. This EVA material is widely used as styling and functional elements in said bags, backpacks, pouches next to many other application in  the soft goods, shoe and even apparel industry.
