Abstract:
1. An omnidirectional speaker comprising, in combination: a high frequency driver which generates sound over a high frequency range and has a first diameter; a high frequency waveguide having a second diameter which is larger than the first diameter; a first midrange driver having a third diameter and a second midrange driver having a fourth diameter, wherein each midrange driver generates sound over a middle frequency range and the first midrange driver faces the second midrange driver; a first midrange waveguide corresponding to the first midrange driver and having a fifth diameter; and a second midrange waveguide corresponding to the second midrange driver and having a sixth diameter, wherein the fifth diameter is larger than the third diameter and the sixth diameter is larger than the fourth diameter; wherein both of the midrange frequency waveguides are positioned between the first midrange driver and the second midrange driver so as to block a direct path from the first midrange driver to the second midrange driver, and the midrange waveguides have a differentiable surface.
