Abstract

A stringed musical instrument having an instrument body, a neck mounted on and extending from said body, and at least one string, an end of which is secured to the extremity of the neck remote from said body and an end of which is secured to said body, this string being under tension and extending adjacent to the neck and the body between its ends, can be improved by pivotally mounting the neck on the body and by using a cam and cam follower structure to adjust the position of the neck relative to the body. The cam and cam follower structure is employed so as to equalize the component of the force exerted by the string on the neck tending to deform the neck. Preferably the instrument has two somewhat flexible resonator structures within the body of the instrument and means connecting both of the resonator structures to a bridge supporting the string or strings of the instrument. These connecting means are employed to transmit vibration to both of the resonator structures.

Dependent claims

A stringed, resonator type musical instrument having an instrument body, a neck mounted on and extending from said body, at least one string extending along said neck and across the top of said body, a bridge engaging and supporting said string on said body, and a resonator means located in said body generally beneath said bridge and mechanically connected to said bridge in which the improvement comprises:

a second resonator means located within said body generally parallel to said first mentioned resonator means beneath said first resonator means, and
mechanical means for transmitting vibration from said bridge to both of said resonator means,
said mechanical means including a rigid spider having a centrally located hub and a rod extending from said hub,
said bridge being mounted on said hub so as to extend therefrom, the ends of the legs of said spider remote from said hub engaging said first resonator means adjacent to the periphery of said first resonator means,
said rod extending through said first resonator means adjacent to the periphery of said first resonator means,
said rod extending through said first resonator means adjacent to the center thereof and connecting said hub with the center of said second resonator.
