The way SoundClip works isn’t all that hard to understand. The iPhone emits a fair amount of acoustic energy through the speaker. Unfortunately, many of these sound waves are directed down and away from the user. SoundClip reflects them toward you so you can hear them better.

But how does it actually amplify? The dimensions and shape of the conical chamber create a resonance chamber facilitating the attenuation of some frequencies, and the amplification of others. The next part is the trickiest. We tuned the resonance chamber to actually improve the sound from your iPhone, resulting in a frequency response that is flatter, and more natural sounding.
