摘要:
A surface mounted loudspeaker design is provided that mitigates the interference between direct low frequency (LF) energy and reflected LF energy by breaking the LF energy from an LF driver into multiple paths using one or more of waveguides, driver load plates, and enclosure ports to diffuse the reflected energy and minimize frequency response errors. One or more embodiments of the present disclosure provides a loudspeaker have multiple acoustic exits strategically designed and located to generate, for example, three major wave front arrivals—2 source and 1 reflection—at target angles with favorable lag times, mitigating the cancellation notching and frequency errors that occur in conventional loudspeaker designs.
