ACOUSTIC WAVEGUIDE

摘要

A high frequency waveguide and methods relating to the design and use of the waveguide are described. The waveguide can include an acoustic input to receive an audio input signal from a high frequency driver, an acoustic output to broadcast sound, and a plurality of acoustic paths extending from the input to the output. A first path of acoustic paths is divided into two paths when a width of the first path is greater than ½ wavelength of a highest frequency at the input. In an example, each of the plurality of acoustic paths carries across all frequencies from the high frequency driver. In an example, the paths each have a first port receiving audio and a second port outputting audio, and the paths enlarge from the first port to the second port.

1. A high frequency waveguide comprising:
an acoustic input to receive an audio input signal from a high frequency driver; an acoustic output to broadcast sound; and a plurality of acoustic paths extending from the input to the output, wherein a first path of acoustic paths is divided into two paths when a width of the first path is greater than ½ wavelength of a highest frequency at the input.
