Description

Apparatus for establishing tone of pizzicato effect for a piano}

The present invention relates to a piano, and more particularly, to an apparatus for implementing a high quality pizzicato tone in a piano.

The piano is played by a hammer that acts upon pressing the key, and its configuration includes a plurality of pedals, keys, hammers, escapes that return the hammer, and strings that are played by the hammer. have.

When the pianist presses the piano key, the movement of the keyboard is transmitted to the hammer, knocking the string in a tense state, producing a sound. The levers, pivots, springs and pads are called escapements, which transmit and restore the movement of the keyboard and enable continuous operation.

1 illustrates the operation of a conventional grand type piano.

When the keyboard 102 is pressed, the support 110 is turned upward, rotates in the 182 direction about the center pin 112, and the L-shaped jack 120, Operation of a variety of complex repeating mechanisms, such as a repetition lever 123, springs 160, regulating buttons 162, spoons 164 and actuating members 132 By rotating the hammer 130 at the end of the wooden shank (string) (string) (ie, the direction of the arrow 184) to rotate.

2 is a schematic side cross-sectional view of a conventional upright (upright or upright) type piano.

When the keyboard 102 is pressed, the hammer 130 expresses the string 140 by the escapement 100, and if necessary, after the hammer 130 is released, the damper 131 is realized by the pedal to vibrate. The sound of the strings will be killed, and the damper or monophonic device is equally applicable to the grand piano. Reference numeral 40 is a pedal, 22 is a hitch pin to fix the string, and 17 is a bridge.

As shown in FIGS. 3A and 3B, the damper 131 has a length formed along the length of the string to catch vibration of one string 140.

131a and 131b are schematic views of an upright type and a grand type damper, respectively.

On the other hand, there are three types of pedals that are applied to both the grand type and the upright type as described above, one of which is a damper pedal for quiet sound, one of which is a pedal for operating the damper, and one of which is a pedal that strongly harmonizes. .

However, the piano having such a structure has a disadvantage in that a voice that can be played with a string instrument such as a violin or a classical guitar cannot implement a pizzicato tone at all.

As the genre of music has recently diversified, and various voices are required for piano performers, jazz pianists are trying to realize the improved pitch tone using conventional pianos. He uses his hands to grasp the strings of the keys that he opens and presses to achieve his desired pizzicato tone.

Accordingly, the present invention is to provide an apparatus capable of implementing pizzicato, which is one method for implementing more various tones in a piano.

<Brief description of symbols for the main parts of the drawings>

31a, 31b: pizzicato damper

40: pedal

In order to achieve the above object, the present invention provides an apparatus including a pizzicato damper for holding a plurality of strings of the piano, a return mechanism for enabling the operation and release of the pizzicato damper, and an operation unit for operating the return mechanism. do.

The actuator is preferably a pedal.

The return mechanism is preferably a mechanism for returning by lever action of the pedal.

The return mechanism is preferably an escapement.

The pizzicato damper preferably has a width that can hold all the strings of the piano.

The pizzicato damper is characterized in that it is a material that can absorb elasticity, such as rubber or leather.

The pizzicato damper is preferably located near the bridge of the string.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 4a is a view showing a structure of a damper for the pizzicato that can be applied to the upright type piano according to the present invention, as a separate pizzicato damper having a different function from the conventional damper, implements pizzicato according to the present invention Damper.

As shown in the figure, the pitcher damper 31a is wide enough to catch the vibration of the plurality of strings 40, and preferably, it is possible to hold all the strings 40 of the piano.

That is, when the specific string is expressed by using the keyboard in a state where all of the plurality of strings are held using the pizzica damper 31a, the tone of the pizzicato is realized.

4B is a view showing the structure of a damper 31b for pizzicato that can be applied to a grand piano.

Like this, as shown in Fig. 4A, when a plurality of strings are displayed in a state where vibrations can be attenuated by using a pizzicato damper, a pizzicato tone is realized.

4A and 4B, the surface of the damper illustrated in FIG. 4B is in contact with the string, and is preferably a material capable of absorbing elasticity such as leather, rubber, or fleece.

5 illustrates an apparatus applied to the upright type according to the present invention. As shown in the drawing, when the lever means, that is, the pedal 40 is pressed, the intermediate member 45 rotates about the fixed center 40a. In this case, the pedal 40 and the intermediate member 45 may be integrated.

When the operating member 47 moves up and down along the inclined surface 47a attached to the end of the operating member 47, the operating member 47 is a guide fixed to the upper lid (not shown) of the piano. Left and right movement along the 49 to operate the pizzica damper 31a. At this time, a spring is attached to one end of the guide 49 to return the left and right movements of the operating member.

Figure 6 shows the simplest example of the device for implementing the pitch tone tone of the piano applied to the grand type according to the present invention.

As shown in the figure, when the pedal 40 is pressed, the elastic member 41 connected to the other end of the pedal is lifted by the fixed center 40a, and the rotating member 42 connected near the other end of the elastic member is fixed center ( 42a), the operation member 43 connected to the other end of the rotating member is lowered down, and the pizzicato damper 31b at the end of the operating member 43 catches the vibration of the string.

The dampers shown in Figs. 5 and 6 preferably operate near the bridge, and are suitable for realizing a high quality pizzicatone.

The elastic member 41 may be a member such as an elastic spring to be returned when the pedal force of the pedal 40 is released, or may be replaced with various devices capable of implementing a return means.

As seen above, according to the present invention, it can be applied to both upright and grand type pianos, and the ones shown in FIGS. 5 and 6 are one example, and return devices for various various dampers may be configured. , All belong to the scope of the present invention.

As described above, the apparatus according to the present invention has the advantage that it is possible to easily configure the disconnection sound such as pizzicato, so that it is possible to implement various tones even in the piano, and thus also in the interpretation and expression of the pianists' songs. The range of expression is widened.

That is, to implement one additional tone is a very important task in the musical instrument field is that the new tone is added to the piano due to the present invention.
