Stringed Musical Instrument Body and Neck Assembly (Ovation Guitar)

Year: 2002

This patent describes an acoustical stringed instrument featuring a hollow body with a composite material top member and bowl-shaped back member, combined with a neck member that mounts to the body at two points — at the upper and lower sections of the body side wall — to provide rigid alignment in all three axial directions. The neck member includes an elongated upper portion extending upwardly from the body and an elongated lower portion extending through the hollow interior of the body, with upper and lower mounting means fixed to the inner side wall surfaces. This dual-point neck/body connection significantly reduces the need for traditional structural reinforcements such as neck blocks and torsion bars, improving both structural integrity and acoustic performance.

Ovation Guitar Top 1983 German Construction Patent

Year: 1983

German patent for a guitar top/soundboard made from a single molded plastic composite part (approx. 40% glass fiber, 60% synthetic resin). Features integral concentric circular reinforcing ribs around the sound hole and diverging straight ribs running lengthwise, plus an integral peripheral ledge and optional integral bridge. The composite construction provides consistent reproducible acoustic properties, high stiffness-to-weight ratio, and immunity to temperature and humidity changes compared to traditional wood soundboards. Filed in Germany on 4 June 1982 with US priority date 20 July 1981 (US 285070).

Stringed Musical Instrument Neck and Body Structure with Metal Stiffener and Releasable Joint

Year: 1980

This patent describes a guitar neck reinforced by an elongated metal stiffener embedded in the main neck part, which carries a tension rod held in a bowed condition to resist bending under string loads. The stiffener's lower end includes a tongue that fits into a conforming recess in the instrument body, with laterally extending flanges that engage the outside surface of the body to provide resistance to neck movement in any direction. The joint design allows the neck to be readily assembled and disassembled from the body while maintaining a firm, acoustically sound connection and a neat, close-fitting joint line between the neck and body.

Ovation Guitar Stringed Instrument Construction with Adjustable Neck Stiffener and Tension Rod

Year: 1979

This patent describes an improved guitar neck construction featuring a metallic stiffener embedded in the main neck part along with a tension rod, both made of high modulus of elasticity materials, allowing precise adjustment of neck bending to counteract string forces. The stiffener includes a rearwardly extending heel at its lower end that connects firmly to the instrument body through threaded fasteners passing through a massive block in the bowl. The system is highly sensitive to adjustment nut rotation, providing a wide range of bending compensation while maintaining a rigid, unyielding connection between the neck and the hollow composite bowl body.

Stringed Instrument Neck with Peghead featuring Metallic Frame and Foamed Plastic Construction

Year: 1978

This patent describes a neck for a stringed musical instrument consisting of a one-piece metallic frame running substantially the entire length of the neck, combined with structural foamed plastic to form the body of the neck including the fingerboard. The peghead portion features a modular design where a mounting plate cooperates with the peghead frame section, allowing different peghead styles and machine head arrangements to be achieved using the same basic frame. This construction enables quantity manufacture of necks at low unit cost while accommodating various peghead designs.

Guitar Construction

Year: 1977

Patent for a guitar body design featuring two discrete sound openings located on either side of the longitudinal center line in the upper bout, replacing the conventional single center sound hole. This construction allows for a thinner sound board with improved bracing patterns, enabling better acoustic response particularly in the first and second harmonic modes of vibration. The design is foundational to the Ovation Adamas guitar series.

Guitar Construction

Year: 1970

Patent for Ovation guitar construction with an innovative soundboard bracing arrangement. Features a one-piece curved fiberglass bowl body with a flat wooden soundboard. The bracing consists of two main braces (top and bottom) arranged obliquely to the soundboard center line, forming a V-shape pattern, with multiple fan braces spaced transversely between them. This arrangement causes the soundboard to resonate at a large number of different frequencies across the full audible range, producing a fuller, richer tone. Includes variations for both folk-style and classic-style guitars. Filed June 8, 1970; patented April 18, 1972.

Ovation Guitar Construction 1967 Patent

Year: 1967

Foundational Ovation guitar construction patent describing a guitar with a soundbox made from impregnated fabric (fiberglass) body and a thin wooden soundboard. The bowl-shaped body is made from plies of glass fabric pre-impregnated with epoxy resin. Features a tapered soundboard providing maximum strength at the neck joint while allowing vibration freedom at lower bout, wooden bracing ribs, L-shaped profile for body-soundboard connection, and an adjustable neck tension rod within a curved bore to compensate for string tension. Includes non-skid surface area on the body. Filed January 27, 1967; patented October 28, 1969.
