(Technology)

The present invention relates to an electronic keyboard musical instrument, in particular, to the keyboard structure of the electronic keyboard musical instrument that can not only feel the after-touch feeling that is almost the same as the after-touch feeling that is felt in the acoustic piano, but also minimize the impact applied to the player's finger from the hammer. It is about.

(Background)

With the development of electric and electronic technology, electronic instruments that generate the sound of traditional acoustic instruments using electronic devices have been widely developed. Pianos (or digital pianos, electric organs, etc.) have emerged.

Traditional acoustic pianos are played by generating sound by hammering the strings by the mechanical force of the keys, but the electronic piano stores digital electronic sounds corresponding to each key in electronic circuits in advance. The electrical contact is connected to play the principle that the corresponding sound is generated.

Depending on how the electronic piano is designed, the piano can play not only the piano sound but also the sounds of other instruments (violin, organ, trumpet, etc.), and in the case of the supplementary type, it is cheaper than the acoustic piano. It is widely used for learning.

Since an acoustic piano is a hammer that strikes a string when a key is pressed, there is a unique feeling (generally called a “touch”) that is transmitted from the hammer to the player's hand through the keyboard. Along with the development, it has continually evolved to provide the best touch to the player, and this touch on an acoustic piano has become one of the most familiar and important elements in piano performance.

In principle, many studies have been conducted to make the sound feel the same as the touch that is accumulated and accustomed to the acoustic piano even in the electric piano that does not require a hammer because sound is generated when the electric contact is connected by pressing a key.

One of the most representative technologies that make the electronic piano feel a touch is that the weight of the hammer is applied to the keyboard when the keyboard is operated by connecting a hammer (weight part) that is not necessary to make a sound to the keyboard like an acoustic piano. It is a keyboard structure to be transmitted.

FIG. 10 is a view showing a conventional electronic piano key structure to which a hammer is applied, in which FIG. 10A is a diagram in which a key is not pressed, and FIG. 10B is a diagram in which a key is pressed.

As shown in the drawing, the conventional electronic piano keyboard structure 100 has a structure including a frame 110, a keyboard 120, a hammer 130, and a contact 140.

One end of the keyboard 120 is rotatably installed on the bracket 111 of the frame 110, and the contact pressure part 121 and the hammer pressure part 122 are formed at a predetermined interval at the interruption of the key 120. When the other end of the keyboard 120 is pressed, the contact pressing unit 121 presses the contact 140 to generate a sound, and the hammer pressing unit 122 is rotatably installed on the pedestal 131. By pressing the action portion 132 of the keyboard 120, the weight of the weight portion 133 of the hammer 130 is applied, and finally, when pressing the keyboard 120, the touch feeling similar to the touch feeling received from the hammer of the acoustic piano I feel it.

However, although the conventional keyboard structure 100 as shown in FIG. 10 has an effect of obtaining a touch feeling similar to that of an acoustic piano, there is a problem in that an after touch feeling applied to the acoustic piano keyboard is not felt.

For example, in the case of an upright piano (a vertically mounted string), an acoustic piano, when the hammer strikes the string, when the key reaches a certain position, the path by which the force applied to the keyboard is transmitted to the hammer is cut off. The load on the hammer is removed, and this disconnection removes the weight of the hammer transmitted to the finger through the keyboard the moment the hammer strikes the string, making the player feel that the hammer hit the string ( In this sense, the sound is detected when the finger is generated, which is generally referred to as 'after-touch feeling'), and in the case of the conventional keyboard structure 100 of FIG. 10, the weight of the hammer strikes the keyboard from the beginning to the end. The problem is that you can't feel the aftertouch because it stays on and you can't play sensual and sophisticated. It is.

As a proposal for imparting an after touch feeling to the electronic piano keyboard, there is a 'keyboard structure of a digital piano' of Korean Patent Laid-Open Publication No. 10-2006-0082959 (published on July 20, 2006). The keyboard structure of the '959 makes a step on the working part of the hammer that the hammer pressing part contacts, so that the hammer pressing part is slightly dropped from the step part when sliding along the working part, so that it feels like an after-touch feeling.

In the '959's keyboard structure, you can feel the aftertouch of the acoustic piano's aftertouch similar to the drop in the step, but you'll get used to it because the hammer's load remains on the keyboard even after it's dropped in the step. There is a limit that the feeling is different from the aftertouch feeling of the acoustic piano.

Another problem with the conventional keyboard structure of FIG. 10 and the improved '959 keyboard structure is that, as in FIG. 10B, the shock and vibration when the weight portion of the hammer strikes the frame (or its cushion) may cause the keyboard to fail. It is directly transmitted to the player's finger through the impact on the player's hand, thereby making it easy to fatigue the hand, as well as the possibility of chronic injury to the finger joints.

That is, in the case of an acoustic piano, the path of the force transmission between the keyboard and the hammer is cut off while the hammer strikes the string, so that the impact of the hammer hitting the cushion of the frame and the like is transmitted directly to the player's finger through the keyboard. However, the conventional keyboard structure of Fig. 10 and the keyboard structure of '959 have a continuous connection of the force transmission path between the hammer and the keyboard, so that the impact generated when the hammer strikes the frame is applied to the player's finger through the keyboard. Is passed on as is. This problem of impact is the same when the weight stops in the air without hitting the frame.

An object of the present invention is to solve the problems of the prior art related to the key structure of the electronic keyboard musical instrument as described above, and not only can feel the same after-touch feeling as the after-touch feeling which is an essential element of the acoustic piano, but also from the hammer. The purpose of the present invention is to provide a keyboard structure of an electronic keyboard musical instrument which can minimize the impact transmitted to the player's finger through the keyboard to the level of an acoustic piano.

According to the present invention, a keyboard structure of an electronic keyboard musical instrument is provided.

The pressurization state of the second acting portion against the acting portion is released.

Preferably, the keyboard structure of the present invention is a delay for temporarily delaying the upper rotation of the first acting portion so that the upper home position rotation of the first acting portion of the hammer member is not faster than the in situ rotation of the second acting portion of the jack member. The member further includes.

Preferably, the delay member is an elastic bar whose one end is in contact with the upper surface of the first acting portion of the hammer member and the other end is fixed to the upper pen member to apply a resistive elastic force to the first acting portion to temporarily delay the upper rotation.

Hereinafter, with reference to the accompanying drawings will be described in detail the keyboard structure of the electronic keyboard musical instrument according to the present invention. The following specific examples are only illustrative of the keyboard structure of the electronic keyboard musical instrument according to the present invention, and are not intended to limit the scope of the present invention.

1 to 9, the key structure 1 of the electronic keyboard musical instrument according to the present invention is basically a keyboard 10, upper pen member 20, hammer member 30, jack member 40 And an electrical contact 50 and a release member 60, these members are suitably arranged and mounted on the frame 2 which forms the skeleton of the keyboard of an electronic keyboard musical instrument such as an electronic piano.

In the present invention, the electronic keyboard musical instrument is used to mean various electronic musical instruments that use a keyboard such as an electronic organ as well as an electronic piano described mainly below.

1 to 4, an example of the keyboard structure of the electronic keyboard musical instrument according to the present invention will be described.

The keyboard 10 is a conventional keyboard widely used in electronic keyboard musical instruments. In the accompanying drawings, only one keyboard is shown for simplicity of the drawings.

As with the usual keyboard, one end of the keyboard 10 in the present invention is rotatably provided to the frame 2. The frame 2 positioned below the keyboard 10 may be equipped with a cushion member 12 for cushioning the collision between the frame 2 and the keyboard 10. Since the rotational structure of the keyboard 10 corresponds to a general technique well known in the related art, a detailed description thereof will be omitted.

The upper pen member 20 is provided below each keyboard 10. In the present invention, the name of the member No. 20 is a 'uppen member', and thus, a member for transmitting a keyboard operation to a hammer in an acoustic piano is adopted as 'uppen'.

One end of the upper pen member 20 is rotatably installed on the frame 2 by the rotation shaft 22. When the key 10 is pressed, the upper pen member 20 is pressed downward by the downward rotation of the keyboard 10. In the illustrated embodiment, the projection 11 is formed on the lower surface of the keyboard 10, and when the keyboard 10 is pressed, the projection 11 presses the upper surface of the upper pen member 20 to interlock with the downward rotation of the keyboard 10. The upper pen member 20 is also rotated downward.

The upper pen member 20 is attached with an elastic member 23 (eg, upper pen spring). The elastic member 23 provides a restoring force to rotate the upper pen member 20 in the original position without pressing the keyboard 10, and thus, when the force (pressing force) applied to the keyboard 10 is removed, the upper pen member 20 The key 10 is returned to its original position by pushing the keyboard 10 upward while rotating upward.

The hammer member 30 is provided below the upper pen member 20. The hammer member 30 is rotatably mounted to the pivot shaft 33 installed on the frame 2, and extends downwardly of the upper pen member 20 about the pivot shaft 33 (of the pivot shaft 33 in the drawing). The right side is provided with a first action part 31 which interacts with the jack member 40, which will be described later, and on the other side (the left side of the pivot shaft 33 in the drawing), a weight part for providing a touch feeling to the keyboard 10 ( 32). The frame 2 around the weight part 32 may be provided with a cushion member 34 for cushioning the collision between the weight part 32 and the frame 2.

The jack member 40 is rotatably installed on the upper pen member 20 around the pivot shaft 43 installed at one point of the upper pen member 20, and operates the upper pen member 20 to operate the hammer member 30. It acts to deliver. One side of the jack member 40 (below the pivot shaft 43 in the drawing) is provided with a second acting portion 41 that presses the first acting portion 31 of the hammer member 30 (contacts each other and transmits force). Preferably, the other side (right side of the pivot shaft 43 in the figure) of the jack member 40 is provided with a trigger portion 42 which interacts with the release member 60 described later.

The jack member 40 has an elastic member 44 that provides an elastic force to the jack member 40 such that the second acting portion 41 elastically returns to its original position to press the first acting portion 31. Jack spring) is installed.

According to the structure of the keyboard 10, the upper pen member 20, the hammer member 30 and the jack member 40 as described above, the second action portion 41 has a first action in a state in which the keyboard 10 is not pressed. Located in the original position to press the part 31, and when the key 10 is pressed in this state, the downward rotation of the keyboard 10, the downward rotation of the upper pen member 20, and the weight of the hammer member 30 By the upward rotation of (32), the player can feel the touch by the load of the weight portion 32 of the hammer base (30).

The electrical contact 50 is a part of a conventional electronic keyboard musical instrument electronic circuit that is pressed to press the keyboard 10, the electrical contact is connected to generate a sound corresponding to the corresponding keyboard 10.

The electrical contact 50 is installed in a rotation path such as the keyboard 10 or the upper pen member 20, and is pressed when the keyboard 10 is pressed to a predetermined position. The illustrated embodiment shows an example in which the electrical contact 50 is installed below the contact pressurizing portion 21 protruding downwardly on the other end of the upper pen member 20, whereby the upper pen member is pressed by the keyboard 10. When the 20 is rotated below a predetermined position or more, the contact pressing unit 21 presses the battery contact 50 to generate a corresponding sound. Although not shown, it is natural that the electrical contact 50 may be operated in a rotation path of another member such as the keyboard 10 or the hammer member 30 instead of the upper pen member 20.

The release member 60 presses the second acting portion 41 of the jack member 40 against the first acting portion 31 of the hammer member 30 when the key 10 is pressed to a predetermined predetermined position. It is a member to release. When the key 10 is pressed to the predetermined position as the release member 60, the pressing state of the second acting portion 41 of the jack member 40 against the first acting portion 31 of the hammer member 30 is released. The configuration is not particularly limited.

In the illustrated embodiment, the jack member 40 is formed in an approximately L shape by including a trigger portion 42 formed at a predetermined angle with the second acting portion 41 about the rotational shaft 43. The example which installed the columnar release member 60 under the trigger part 42 is shown. Attached to the upper end of the release member 60 is a cushion member 61.

According to the configuration of the jack member 40 and the release member 60 as described above, when the keyboard 10 is pressed over a predetermined predetermined position, the release member 60 presses the trigger portion 42 to press the jack member 40. It rotates, and the pressurization state of the 2nd action part 41 with respect to the 1st action part 31 is released.

1 to 4, the operation of the keyboard structure of this embodiment will be described.

In the initial state in which the keyboard of FIG. 1 is not pressed, the keyboard 10 is pressed upward by the elastic member 23 (uppen spring) and the upper pen member 20 to return to its original position, and the jack member 40 By the action of the elastic member 44 (jack spring), the second acting portion 41 of the jack member 40 is in a state capable of pressing the first acting portion 31 of the hammer member 30, the hammer member The weight part 32 of 30 rotates below.

When the key 10 starts to be pressed as shown in FIG. 2 (for example, when the vertical movement width of the end of the key is 10 mm, for example, about 7.6 mm is pressed), the key 10 is the upper pen member 20. Presses, the hammer member 30 is pressed by the second acting portion 41 of the jack member 40 so that the weight portion 32 is rotated upwards, the player 32 as in the acoustic piano You will feel the touch by). In this process, the contact pressing unit 21 of the upper pen member 20 presses the electrical contact 50 to generate a corresponding sound, and the trigger unit 42 of the jack member 40 has a release member 60 below. ), But the trigger portion 42 is not pressed by the release member 60 yet.

When the key 10 is pressed further to the lowest position (eg, 10 mm) as shown in FIG. 3, the trigger portion 42 of the jack member 40 is pressed by the release member 60 to thereby release the jack member 40. It is rotated, whereby the first acting portion 31 of the hammer member 30 is released from the pressurized state of the second acting portion 41 of the jack member 40, the hammer member was delivered to the keyboard 10 at this moment Since the weight of the weight portion 32 of the 30 disappears, the player can feel the moment of release of the pressurized state of the first acting portion 31 and the second acting portion 41 and the disappearance of the load with an after-touch feeling. .

As soon as the after-touch feeling is sensed, the hammer member 30 rotates until it reaches the upper cushion member 34 of the frame 2 by inertia, and then rotates downward by its own weight as shown in FIG. 4. At this time, the first acting portion 31 of the hammer member 30 is released from the pressurization of the second acting portion 41 of the jack portion 40, the first acting portion 31 is the jack member 40 It is in a state of sliding along the inclined surface 45 of the, so the impact of the weight portion 32 hit the cushion member 34 is not transmitted to the player through the keyboard 10, the hammer member receives the player ( The impact of 30 can be minimized.

Then, when the player does not press the keyboard 10, the upper pen member 20 and the keyboard 10 by the action of the elastic member 23 (upper spring) of the upper pen member 20 is rotated upwards to return to the original position The jack member 40 is also rotated by the action of the elastic member 44 (jack spring) so that the second acting portion 41 of the jack member 40 presses the first acting portion 31 of the hammer member 30 again. The hammer member 30 is also rotated by the weight of the weight part 32 so that the weight part 32 is located at the lowermost position and the first action part 31 is located at the uppermost position. It returns to the state of FIG.

1 to 4, a jaw is formed at one side of the second acting portion 41 of the jack member 40, and the jaw is pressed to hold the first acting portion 31 of the hammer member 30. Although an example is shown, as illustrated in FIGS. 5A to 5C which are other embodiments of the keyboard structure according to the present invention, the end of the second acting portion 41 is raised to the end of the first acting portion 31. Naturally, various other structures may be applied, such as pressing down in a state.

Also in the embodiment of Fig. 5, the second acting portion 41 in the longitudinal direction pushes the first acting portion 31 in the horizontal direction downward so that the weight portion 32 of the hammer member 30 rotates upward. Then, the trigger portion 42 of the jack member 40 is pressed by the release member 60 so that when the jack member 40 is rotated, the first acting portion 31 is released from the pressing of the second acting portion 41. As a result, the load of the weight part 32 that has been transmitted to the keyboard 10 disappears to feel an after-touch feeling, and the effect thereof is substantially the same as that described above with reference to FIGS. 1 to 4.

The first acting portion 31 of FIG. 5 may be coated with leather or rubber, for example, so as to provide an appropriate friction force.

On the other hand, the player does not press the keyboard 10, so that the keyboard 10, the upper pen member 20, the hammer member 30, and the jack member 40 are not shown in Figs. 4 and 5C. In the process of returning to the state of A, when the upper home position rotation of the first acting portion 31 of the hammer member 30 is faster than the home position rotation of the second acting portion 41 of the jack member 40, the second It may be somewhat delayed to return to the original position of FIGS. 1 and 5A where the acting portion 41 can press the first acting portion 31.

In order to prevent this, as illustrated in FIGS. 6 to 9, in another keyboard structure 1 according to the present invention, the player does not press the keyboard 10, the keyboard 10, the upper pen member 20. When the hammer member 30 and the jack member 40 are returned to their original positions, the upper rotation of the first acting portion 31 of the hammer member 30 is caused by the second acting portion 41 of the jack member 40. It may further include a delay member 70 for delaying the upper rotation of the first action portion 31 so as not to be faster than the original position rotation.

Delay member 70 of the illustrated embodiment, one end 72 of the upper surface of the first acting portion 31 of the hammer member 30 so as to apply a proper resistance force to the upper rotation of the first acting portion 31. The other end 73 is in contact with, for example, in the form of an elastic bar 71 fixed to the upper pen member 20. The elastic bar 71 applies a resistance elastic force to the upper rotation of the first acting portion 31 to delay the upper rotation of the first acting portion 31.

Since the resistance elastic force of the delay member 70 is set not to be greater than the lifting force of the first acting portion 31 due to the weight of the weight portion 32, the home position rotation of the hammer member 30 is only delayed temporarily, and eventually It overcomes the resistive elastic force of the delay member 70 and returns to the original position.

In forming the delay member 70 with the elastic bar 71, as shown in FIG. 6, the elastic bar 71 is formed to have a constant curvature to impart an appropriate resistance elastic force to the delay member 70. . In addition, the one end 72 of the elastic bar 71 is folded up to prevent the one end 72 of the elastic bar 71 from being unintentionally caught by the first acting portion 31.

7, one end 72 of the elastic bar 71 is formed by splitting one end 72 of the elastic bar 71 positioned in the rotation path of the second action part 41 like a fork. ) Can be prevented from disturbing the rotation of the jack member (40).

6 to 9, the operation of the delay member in the keyboard structure of the present embodiment will be described.

As shown in Fig. 6, in the initial state in which the keyboard 10 is not pressed, one end 72 of the delay member 70 presses the first acting portion 31 rotated to the uppermost side from the top to the bottom. Although the elastic modulus of the delay member 70 is not greater than the lifting force of the first acting portion 31 due to the weight of the weight portion 32, the hammer portion 30 has the weight portion 32 at the lowermost side. Maintain the original position at.

As shown in FIGS. 7 and 8, in the process of starting to press the keyboard 10 to form a touch feeling and an after touch feeling by the weight part 32, one end 72 of the delay member 70 is elastic. In the state in contact with the first acting portion 31 by the downward movement along the downward rotation of the first acting portion 31.

And, as shown in Figure 9, when the weight portion 32 is rotated to the top side to start the downward rotation (that is, the time when the first acting portion 31 starts to rotate upward after the rotation to the lowest side) The elastic force of the delay member 70 temporarily resists upward rotation of the first acting portion 31 so that the in-situ rotation of the jack member 40 is not hindered by the first acting portion 31.

According to such a delay member 70, the resistance elastic force of the delay member 70 is the upper side of the first acting portion 31 when the first acting portion 31 is rotated upward by the weight of the weight portion 32. Since the rotation is temporarily delayed and the jack member 40 is rotated to its original position while the upper rotation of the first acting portion 31 is temporarily delayed, the second acting portion 41 is the first acting portion 31. ) Is smoothly returned to the position where it can pressurize.

6 to 9 show an example in which the elastic member 23 provides a restoring force for rotating the upper pen member 20 to its original position, and an elastic bar member is applied without using coil springs as shown in FIGS. 1 and 5. The elastic member 23 of this embodiment also provides the elastic force to rotate the upper pen member 20 to the upper side is the same as the specific example of FIG.

According to the key structure of the electronic keyboard musical instrument according to the present invention described above, only by employing a simple structure that mediates the upper pen member 20 and the jack member 40 between the keyboard 10 and the hammer member 30, Not only can you feel the after-touch feeling, which is similar to the after touch, an essential element of the acoustic piano, which was a weakness in the keyboard structure of the keyboard instrument, but also minimizes the impact transmitted from the hammer to the player's finger through the keyboard to the level of the acoustic piano. It can be effective.
