Passive Directional Acoustical Radiating |
摘要 |
An acoustic apparatus, including an acoustic driver, acoustically coupled to a pipe to radiate acoustic energy into the pipe. The pipe includes an elongated opening along at least a portion of the length of the pipe through which acoustic energy is radiated to the environment. The radiating is characterized by a volume velocity. The pipe and the opening are configured so that the volume velocity is substantially constant along the length of the pipe.
