Coaxial speaker with step-down ledge to eliminate sound wave distortions and time delay

摘要

A coaxial speaker assembly ( 10 ) with reduced sound distortion, sound time delay, and polar response distortion. The coaxial speaker assembly ( 10 ) includes a high-frequency speaker system ( 16 ) mounted coaxially with and fitting within a lower-frequency speaker system ( 14 ). A baffle ( 50 ) is secured to a diaphragm ( 48 ) of the high-frequency speaker system ( 16 ). A step-down ledge ( 52 ) is circumferentially positioned adjacent to the baffle ( 50 ) and extends outwardly therefrom. A portion of the sound waves emanating from the high-frequency diaphragm ( 48 ) are reflected off the step-down ledge ( 52 ).
