Abstract
Abstract A guitar synthesizer has a guitar body (10) and a synthesizer portion (20). The body (1) of the guitar extends toward a head (3) in a direction so that an end (11) serving as a first vibratory member in the body base to which a neck (2) is connected, intersects with the neck. A second end (13) serving as the second vibratory member may also intersect with the neck. A non-vibratory portion (12) is interposed between the first and the second vibratory members (11, 13). A reinforcing frame (4) is attached to the head and body to interconnect them with the shortest distance for providing a firm connection from the non-vibratory portion of the body to a part of the head closer to a nut (5) than to the head end. Thus, the connection between the head and the frame is located below the central point of the distance between the nut and the top end of the head. Such a structure suppresses vibrations of the neck and an early attenuation of the fundamental frequency due to the vibration of the strings (7), are avoided.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
226 words
A guitar synthesizer, comprising a guitar body, a bridge provided on the upper surface of said body, a neck having one end attached to said body, a nut and a head provided in the top end portion of said neck, strings stretched between said bridge and said nut, and a pickup for providing a guitar string signal including a fundamental frequency component according to the vibration of each of said strings and a harmonic frequency component thereof; and synthesizer means for generating a guitar synthetizer signal associated with said fundamental frequency component in response to said guitar string signal, said body of said guitar comprising projecting means (11, 12, 13) including a non-vibratory projecting portion (12) located in the vicinity from which said neck extends toward said head, and a mechanical reinforcing frame (4) extending from said non-vibratory projecting portion of said body toward said head, said mechanical reinforcing frame (4) firmly connecting said body and said head along the shortest distance for suppressing vibrations of said neck to prevent an early attenuation of said fundamental frequency component, and wherein said projecting means have two vibratory portions (11, 13), at least one of which intersects with said neck, said non-vibratory projecting portion (12) of said body extending between said vibratory portions in a direction permitting said mechanical reinforcing frame member (4) to extend toward said head.
Claim 2
Dependent Claim
226 words
A guitar synthesizer, comprising a guitar body, a bridge provided on the upper surface of said body, a neck having one end attached to said body, a nut and a head provided in the top end portion of said neck, strings stretched between said bridge and said nut, and a pickup for providing a guitar string signal including a fundamental frequency component according to the vibration of each of said strings and a harmonic frequency component thereof; and synthesizer means for generating a guitar synthetizer signal associated with said fundamental frequency component in response to said guitar string signal, said body of said guitar comprising projecting means (11, 12, 13) including a non-vibratory projecting portion (12) located in the vicinity from which said neck extends toward said head, and a mechanical reinforcing frame (4) extending from said non-vibratory projecting portion of said body toward said head, said mechanical reinforcing frame (4) firmly connecting said body and said head along the shortest distance for suppressing vibrations of said neck to prevent an early attenuation of said fundamental frequency component, and wherein said projecting means have two vibratory portions (11, 13), at least one of which intersects with said neck, said non-vibratory projecting portion (12) of said body extending between said vibratory portions in a direction permitting said mechanical reinforcing frame member (4) to extend toward said head.
Claim 3
Dependent Claim
38 words
The guitar synthesizer of claim 1, wherein said reinforcing frame is connected between said non-vibratory projecting portion (12) of said body and a head portion located closer to said nut than to the top end of said head.
Claim 4
Dependent Claim
