Abstract
A hand-actuated tremolo assembly for an acoustic guitar having a mounting structure for the tremolo device is provided. The tremolo device includes a base plate which is anchored to the guitar by means of a mounting structure disposed on the inside of the sound box of the guitar, and is moveable against stationary pivots by means of an actuator disposed outside of the sound box of the guitar, on the face of tremolo device, for the purpose of varying the tension of the strings of the guitar.

A tremolo assembly to produce a desired tremolo effect in and to preserve the acoustic sound of a substantially hollow acoustic guitar having a substantially hollow sound box comprised of a top sound board and a bottom sound board joined by side walls, comprising
- plate means pivotedly mounted to the top of said sound board for receiving the strings of the guitar,
- actuating means attached to said plate means for actuating pivotal movement of said plate means, and
- support means fixedly attached to the underside of said top sound board at the location of said plate means for supporting said plate means and countering excessive stress placed upon the acoustic guitar by said pivotal movement,
- whereby manual operation of the actuating means causes said plate means to pivot and thus vary the tension of the strings of the guitar to produce the desired tremolo effect.
A tremolo assembly to produce a desired tremolo effect in and to preserve the acoustic sound of an acoustic guitar having a substantially hollow sound box comprised of a top sound board and a bottom sound board joined by side walls, comprising
- plate means pivotedly mounted to the top of said sound board for receiving the strings of the guitar,
- actuating means attached to said plate means for actuating pivotal movement of said plate means, and
- support means fixedly attached to the underside of said top sound board at the location of said plate means for supporting said plate means and countering excessive stress placed upon the acoustic guitar by said pivotal movement,
- whereby manual operation of the actuating means causes said plate means to pivot and thus vary the tension of the strings of the guitar to produce the desired tremolo effect, and
- wherein said plate means comprises a top plate constructed of a porous wooden material and a metal based bottom plate, said top plate being fixedly attached to said bottom plate.
A tremolo assembly to produce a desired tremolo effect in and to preserve the acoustic sound of an acoustic guitar having a substantially hollow sound box comprised of a top sound board and a bottom sound board joined by side walls, comprising
- plate means pivotedly mounted to the top of said sound board for receiving the strings of the guitar,
- actuating means attached to said plate means for actuating pivotal movement of said plate means, and
- support means fixedly attached to the underside of said top sound board at the location of said plate means for supporting said plate means and countering excessive stress placed upon the acoustic guitar by said pivotal movement,
- whereby manual operation of the actuating means causes said plate means to pivot and thus vary the tension of the strings of the guitar to produce the desired tremolo effect, and
- wherein said support means is further fixedly attached to the innerside of said bottom sound board, and
- wherein said support means comprises a mounting structure top plate attached to the underside of said top sound board and a mounting structure back plate attached to the innerside of said bottom sound board and connecting means for connecting said mounting structure top and back plates.
A tremolo assembly to produce a desired tremolo effect in and to preserve the acoustic sound of an acoustic guitar having a substantially hollow sound box comprised of a top sound board and a bottom sound board joined by side walls, comprising
- plate means pivotedly mounted to the top of said sound board for receiving the strings of the guitar,
- actuating means attached to said plate means for actuating pivotal movement of said plate means, and
- support means fixedly attached to the underside of said top sound board at the location of said plate means for supporting said plate means and countering excessive stress placed upon the acoustic guitar by said pivotal movement,
- whereby manual operation of the actuating means causes said plate means to pivot and thus vary the tension of the strings of the guitar to produce the desired tremolo effect, and
- wherein said top sound board includes on its underside a plurality of braces for supporting said top sound board and wherein said support means abuts at least one of said braces, whereby string vibration is transferred through said braces into said top sound board.
A tremolo assembly to produce a desired tremolo effect in and to preserve the acoustic sound of an acoustic guitar having a substantially hollow sound box comprised of a top sound board and a bottom sound board joined by side walls, comprising
- plate means pivotedly mounted to the top of said sound board for receiving the strings of the guitar,
- actuating means attached to said plate means for actuating pivotal movement of said plate means, and
- support means fixedly attached to the underside of said top sound board at the location of said plate means for supporting said plate means and countering excessive stress placed upon the acoustic guitar by said pivotal movement,
- whereby manual operation of the actuating means causes said plate means to pivot and thus vary the tension of the strings of the guitar to produce the desired tremolo effect, and
- further including string termination means attached to the underside of said plate means and pivotal therewith for anchoring the guitar strings, and spring means attached to said string termination means for counterbalancing the tension placed on the strings.
In a substantially hollow acoustic guitar having a substantially hollow sound box, a tremolo assembly, comprising
- tremolo means for varying the tension of the strings of the guitar, said tremolo means pivotedly attached to said sound box,
- support means for supporting said tremolo means, said support means fixedly attached to the inside of the hollow sound box, and
- actuator means attached to said tremolo means for actuating the pivotal movement of said tremolo means and causing a varying tension of the strings of the guitar.
In an acoustic guitar having a substantially hollow sound box, a tremolo assembly, comprising
- tremolo means for varying the tension of the strings of the guitar, said tremolo means pivotedly attached to said sound box,
- support means for supporting said tremolo means, said support means fixedly attached to the inside of the hollow sound box, and
- actuator means attached to said tremolo means for actuating the pivotal movement of said tremolo means and causing a varying tension of the strings of the guitar, and
- further including bridge height adjusting means adjustably connecting said tremolo means to said sound box and wherein said support means include mounting means for receiving said bridge height adjusting means, and said bridge height adjusting means including a section positioned above said hollow sound box for limiting the pivotal motion of said tremolo means, and
- wherein said tremolo means comprises a top plate constructed of a porous wooden material and a metal based bottom plate, said top plate fixedly attached to said bottom plate, and further comprises string termination means for anchoring the guitar strings in the sound box, and spring means for counterbalancing the tension placed on the strings.
A mounting assembly to support a tremolo device in a substantially hollow acoustic guitar having a hollow sound box comprised of a top sound board and a bottom sound board joined by side walls, comprising
- a mounting structure top plate affixed to the underside of said top sound board at the location of said tremolo device and a mounting structure bottom plate affixed to the innerside of said bottom sound board;
- and
- connecting means having at least one support leg for connecting said mounting structure top and bottom plates,
- whereby said mounting assembly provides support to withstand the forces exerted upon the sound box upon actuation of the tremolo device.
