Abstract: In an audio processing system a center point stereo sound processor in combination with a digital transducer alignment sound processor converts regular left and right stereo audio source signals to sum and difference signals, enabling a center stage spatialized stereo acoustic image to be created directly from a forward-directed loudspeaker unit and a sideways-directed dipole loud speaker unit. The forward-directed loudspeaker unit includes one vertically-mounted loudspeaker. The sideways-directed dipole loudspeaker unit is located directly below and to the sides of the forward-directed loudspeaker unit and includes two speaker cones connected in parallel and wired out of phase with each other. The center point stereo sound processor receives a left and right, stereo, audio signal source and converts the left and right signals into sum and difference signals. The sum, left plus right signal drives the forward-directed loudspeaker unit.

Abstract: Our audio cabinet includes a recess in a cabinet wall in which is seated a control panel comprising a rigid plate bent to form a first planar section and a second planar section connected together by a slanted planar section. An exposed face surface of the slanted planar section includes at least one socket for inserting a plug of a cable. The rigid plate has a configuration that is complementary to the configuration of a perimeter of the recess so the plate fits within the recess with the exposed face surface facing the one side of the enclosure. With the plate seated in the recess the socket faces the one side of the enclosure and the exposed face of the slanted section is offset a predetermined distance from said one side to provide clearance for the plug to be inserted into the socket. The dimensions of the recess and angles of the plate are arranged such that an inserted plug is protected from contact with the floor if the audio cabinet is toppled over.

Abstract: A pick-handle is attached to the to the “rear” edge of a conventional pick via a metal shaft. The handle portion is made to be comfortably grasped in the palm of the player's hand while the pick is held in the normal manner between the thumb and forefinger. Stringed instrument playing technique is enhanced by improved control over the pick and increased volume capability due to the increased mass effectively transmitted to the pick from the hand, wrist and arm of the player. Additionally, the invention reduces the strain on the thumb and forefinger by allowing the other fingers to supplement the grip, and also reduces the risk of the pick slipping out of playing position or totally escaping from the thumb/finger grasp. Attachment of the pick to the shaft may be implemented by a spring clip that allows easy removal of the pick and replacement by practically any commonly available pick of the player's choice.

Abstract: For enhancing the frequency response and sustain performance of a stringed musical instrument such as a guitar or electric bass, the present invention provides a mass-increasing device in the form of an adjustable metal U-shaped bracket forming a C-clamp that can be removably attached to the headstock of an instrument such as an acoustic guitar, electric guitar or electric bass. Clamping action is implemented by an screw-clamp assembly having a knurled thumb/finger knob at one end of a threaded shaft and a felt-padded pressure disc affixed at the other end, the threaded shaft traversing the major leg of the C-clamp. The device is normally clamped in place at an optimal location in the headstock near the instrument neck with the minor leg under the strings and the major leg and the screw-clamp assembly located on the reverse side of the headstock. Resilient pads are provided on the clamping pressure points to protect the finish on the instrument headstock.

Abstract: The CPS (center point stereo) system of the present invention is directed to stereo sound reinforcement of live music, particularly with electronically-implemented instruments such as guitars and keyboards that provide a musical source signal at line level. A special CPS processor, converting regular left and right stereo signals to sum and difference signals, enables a center stage acoustic image to be created directly from a forward-directed loudspeaker unit driven from the sum signal and enables left and right spatialized stereo images to be created by recombination with a difference field received indirectly from a sideways-directed special dipole loudspeaker unit conveniently co-located with the forward-directed loudspeaker unit and driven from the difference signal. The CPS processor receives L and R input from the instrument or from an interposed FX (musical effects) or DSP (digital sound process) unit receiving mono or stereo input from the instrument.
