SK59396A3 - Mechanical device for resounding an electric bass guitar - Google Patents

Abstract

Mechanic device for resounding an electric bass guitar allows to resound the strings by means of a lever with the purpose of developing the expression possibilities of this musical instrument. It consists in the fact that in the opening of the guitar's protective cover (2), there is at least one shaped flap (3) flexibly mounted on the side of the guitar's cavity by means of a steel restoring spring (10), which is, at its bottom side, equipped with a stop (6); and on the bottom (7) of the guitar's cavity on a support (11), there is at least one resounding lever (4) mounted pivotally and equipped with a cap (9), whereby between the lever (4) and the bottom (7) of the guitar's opening, a steel spring (5) is mounted.

Description

Mechanical sounding equipment for electric bass guitars

Technical field

The invention relates to a mechanical device for sounding an electric bass guitar.

BACKGROUND OF THE INVENTION

The electric bass guitar, first constructed in the 1940s to this day, has undergone various design changes that have led to greater perfection, reliability and so on. The current bass guitar is already so technically advanced that it changes its function in the music itself.

From the purely accompanying instrument that gave the music the bottom bass tones, today the bass guitar is becoming a solo instrument.

All the structural changes that have been made on the tool so far have always concerned the individual parts of the tool and eliminated their deficiencies eg. tuning accuracy of tuning mechanics, parameters of electromagnetic sensors bridge stiffness and the like.

However, none of these changes has brought a significant change:

1. Instrument sound colors

2. Possibility to use some other finger playing technique while playing the guitar, while the current trend of music and the players themselves are demanding exactly these two fundamental changes.

SUMMARY OF THE INVENTION

The above-mentioned drawbacks are solved by the present invention, which is based on the provision of a mechanical device for the acoustic bass guitar. The mechanical device is located in the opening of the guitar body and consists of at least one shaped flap resiliently mounted on the side of the guitar recess by means of a steel return spring which is provided with a stop on its underside and at least one sounding arm is rotatably mounted on the base of the guitar recess. a steel pen is placed between the shoulder and the bottom of the guitar removal.

By its function, said mechanical device provides a shoulder method of sounding the tool. By striking the string not with the player's finger, but with the wooden hanger, the sound coming from the instrument has a completely different character and color of the sound than all the sounds made so far by any technique played. Other desired sound quality eg. the length of the sustaining tone will be retained, and the dynamics (changing the decibel value of the tone) and the speed of the tone coming from the instrument will be significantly improved in this way of playing. The shoulder method of tone creation emphasizes higher overtone (harmonic) tones in the sound, giving the player more possibility to play in the so-called. flazolety. It also greatly improves playing in chords (unison of multiple tones), enhances the readability of individual tones.

The current trend of music calls for greater speed of consecutive tones. This mechanism fulfills this requirement.

However, the new way of creating a tone does not exclude the possibility of playing in the usual way. By installing the mechanism in the instrument, the player's ability to play in the original way is not limited. The player chooses the playing method that suits him and can use both at the same time.

A further advantage of this mechanism is that by using it, the player has the possibility to lure sounds from the instrument similar to other sounds of musical instruments e.g. dulcimer, bongos, etc.

Overview of the drawings

In FIG. 1 illustrates a mechanical device that triggers the mechanism of an electric bass guitar in a rest position. In FIG. 2 shows the device in the operating position.

EXAMPLES

The device is actuated by a guitar player by pressing or striking the shaped flap 3, which in turn begins to move out of its rest position towards the inside of the guitar. After a short start, it strikes the shorter end of the arm 4, which thus begins to rotate about its anchor 8 in the pedestal 11. The arm is further pushed by the flap within a certain period of time. This happens until the flap stops its movement by touching its adjustable stop 6 on the bottom 7 of the guitar recess. At this point the arm 4 does not yet touch the string of the 1 guitar. The distance between the stopping point of the flap 3 and the contact of the arm 4 with the string 1 overcomes the arm by its inertia force. Then, until the arm 4 hits the string of the guitar, it vibrates it. The string 4, however, must not remain on the string after striking the string, as it would prevent it from further oscillating and the tone emitted from the string would be muted. It is precisely this time and space that it can fulfill this condition between the stopping point of the flap 2 and the point of contact of the string 4 with the string 1. The string 4 partially reflected from the string 1 and partially pressed by the steel tongue 5 immediately leaves the string 1 your home location. If the flap is still in its working position, the arm 4 will come to it but already sufficiently distant from the guitar string so that it can oscillate freely. In this case, the arm 4 returns to its initial position by means of a steel tongue 5 upon release of the flap 2. The flap 2 extends after releasing the finger pressure on it by means of a return spring 10 to its initial position secured by the stop of the flap 2 on the protective cover 2.

Industrial usability

The invention can be used in the manufacture of electric bass guitars that require their expressive possibilities. The device can be installed in the currently produced bass guitars, or it can be installed separately into the produced basses as a separate additional unit.
