Abstract
This invention is an acoustic guitar with two internal waveguides built into the guitar body. Each left and right waveguide is five feet long. The acoustic sound of the guitar is captured by a microphone, a piezo pickup, a pressure transducer pickup, a magnetic pickup under the strings, or any combination of these. It is then sent to an internal electronics package, including an amplifier and an equalizer, which sends the signal to left and right full range speakers. These speakers are mounted at the start of each waveguide. The sound then travels through each waveguide, which increases in size, similar to a horn, toward the end of the waveguide. One quarter wavelength of the lowest frequency is captured, and directed to multiple sound ports toward the end of the waveguides. The materials being considered for this guitar are Maple, Walnut, Rosewood, Mahogany, Sitka Spruce and Baltic Birch.
