Abstract
In some implementations, the device may include multiple waveguides. Additionally, the device may have an inlet for each waveguide in the plurality of waveguides. Each inlet receives sound waves from a different sound source in the plurality of sound sources. The device may also include an exit for each waveguide in the plurality of waveguides. Furthermore, the device may have an output section that is defined by all the exits in the plurality of waveguides. The exits of the waveguides divide the output section into a number of segments that is equal to the number of waveguides. Each waveguide in the plurality of waveguides has an equal pathlength from its corresponding inlet to its corresponding exit at the output section. The output section delivers a coherent wavefront of sound to the acoustic horn.
