Abstract: Systems and methods for speaker assemblies with wide dispersion patterns are disclosed. In one embodiment, a speaker assembly includes at least two speaker drivers and a diffraction baffle affixed to each speaker driver, where each diffraction baffle includes a baffle face having a diffraction slot positioned over the driver and each diffraction baffle is affixed to and sealed to the driver, the area across each diffraction slot is less than the surface area of the driver, each diffraction slot provides a path for substantially all of the acoustic pressure waves produced by the speaker driver to propagate away from the driver and the acoustic pressure waves are within a frequency range determined by the characteristics of the driver, and the width of each diffraction slot in the horizontal direction is equal to the wavelength of a predetermined target frequency.

Abstract: A pickup for use in a stringed musical instrument. The pickup includes a primary transducer that is sensitive to the motion of the musical instrument's strings and is mechanically coupled to the body of the musical instrument. The primary transducer senses the motion of the musical instrument's strings and generates a “string sound” signal in response. The primary transducer is further flexibly coupled to a secondary transducer that is not fixedly attached to the body of the musical instrument. Relative motion between the primary transducer and the secondary transducer generates a “body sound” signal within the secondary transducer. The string sound signal and the body sound signal are combined to generate a signal representing the acoustical response of the musical instrument.
