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.

Abstract: This invention is an acoustic guitar with a floating soundboard. The soundboard is attached to the body with shoulder bolts, rubber grommets, washers, and nuts (no adhesive). This allows the soundboard to float, due to the rubber grommets that will provide a great amount of movement. This results in dramatically greater volume, and improved tone (due to less force required on the guitar strings). The material for the body is Rock Maple, and the other materials are Sitka Spruce, Rosewood and Mahogany.

Abstract: This invention is an acoustic guitar with two internal folded horns built into the guitar body. Each left and right horn is five feet long. The natural acoustic sound inside the guitar is captured by a microphone (not a pickup under the strings), inside the guitar's upper chamber. It is then sent to an internal preamp, which sends the signal to left and right speakers, which are mounted to the compression chamber at the start of each folded horn. It then travels through the throat of each folded horn, which increases exponentially until it reaches the end of the horn. The sound waves are concentrated throughout this shape (does not lose sound energy), and are also directed to left and right exits out the end of the instrument. The material for the body is Rock Maple, and the other materials are Sitka Spruce, Rosewood and Mahogany.
