发明名称 Omnidirectional speaker
摘要 An omnidirectional speaker having a high frequency driver, which generates sound over a high frequency range and which has a first diameter, and a high frequency waveguide having a second diameter larger than the first diameter. A first midrange driver and a second midrange driver have a third diameter and a fourth diameter, respectively. Each midrange driver generates sound over a middle frequency range and the first midrange driver faces the second midrange driver. First and second midrange waveguides have a fifth diameter and a sixth diameter, respectively, and correspond to the first and second midrange drivers, respectively. The fifth diameter is larger than the third diameter and the sixth diameter is larger than the fourth diameter. 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.

主权项 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.
