BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic piano combined with a live piano, such as an upright, which can be used by changing it to an electronic piano with a simple structure.

[0002]

2. Description of the Related Art Conventionally, as is well known, this kind of live piano has a mechanism in which a hammer strikes a string by a keystroke on a keyboard to produce a sound. As the weak sound function of the upright piano, it is generally practiced that the sound is made strong and weak by using a soft felt felt that moves up and down at the contact point of the hammer and the string as shown in FIG.

[0003]

The object of the present invention is to install a rubber pad in which a switch is embedded, instead of the felt actuation mechanism in the conventional soft felt mechanism, thereby providing a live piano and an electronic piano. The purpose is to easily achieve the dual use of the function.

[0004]

According to the present invention, by attaching a rubber pad proposed to a live piano, the function as an acoustic piano and a digital dual piano can be achieved. It is equipped with a rubber pad that can be moved up and down and is rich in cushioning. Switches corresponding to the number of keyboards are embedded in the rubber pads at the positions where the hammers hit, and the switches are opened and closed by the movable tapping of each hammer. Then, the acoustic pedal and the digital are easily switched by the soft pedal, the electronic piano is designed so that no live sound is produced when the digital is used, and the volume control and the headphone can be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings. The live piano (1) shows an upright type that is commonly used, and (2) shows each keyboard of the live piano (1). ing. The keyboard (2) is mounted via a capstan (10) corresponding to each action portion (3) and a wippen (11). The action part (3) has a butt (12) which is rotated by pressing the keyboard (2), and a hammer (4) for hitting the string (5) by the butting (12) is provided on the butt (12). It is connected. Further, a damper lever (14) which can be brought into contact with the string (5) and a damper (13) at the upper end of the damper lever (14) are provided in front of the axle portion (3). Next, this invention is as shown in FIGS. 1 and 2, and quite as conformal string above the conventional dampers felt shown in FIG. 3 with respect to the front surface of the (5) (15), Seo
A connecting rod that can be opened and closed by pressing the foot pedal (8)
A rubber pad (6), which can be installed on the upper end of an elevating and lowering connecting rod in which several movable metal fittings are linked, is installed so as to be vertically movable.
The rubber pad (6) is made of an elastic material such as rubber so that the hammering sound of the hammer (4) is not transmitted to the strings (5). Switches (7) (7) ... Are embedded horizontally in the rubber pad (6). The switches (7) and (7) have 88 keys corresponding to the number of keyboards (2) embedded in the rubber pad (6). The hammer striking portion data is generated by turning on each of them by the hammering force of the hammer (4). Moreover, the switch (7) (7) is made of a strong and durable material that can withstand the striking force of the hammers (4) (4) .... In addition, since the keyboard section data needs to be interlocked with the keyboard (2) due to the sounding structure of the live piano (1), note O is also recorded on the keyboard section.
A switch for FF data is installed. Reference numeral (8) indicates a soft pedal for strength and weakness.

[0006]

When the present piano is used as an electronic piano, the rubber pad (6) shown in FIG. 1 is operated by pressing the soft pedal (8) as shown in FIG. When hanging down in front of the string (5) and pressing the keyboard (2), the tip of the hammer (4) hits the switch (7) embedded in the rubber pad (6) and the switch (7) is turned on. Generate. Then, the damper (13) also comes into pressure contact with the surface of the string (5). Further, the hammer (4) is attached by the rubber pad (6).
Absorbs the tapping sound of, and completely silences the raw sound.

[0007]

As described above, according to the present invention, it is very convenient because it can be installed in the same form as the conventional soft felt, and by operating the soft pedal, it is possible to switch between acoustic and digital. There is an effect that can be easily done. Since the elastic rubber pad which moves up and down on the upper front surface of the string is used, the hammering sound and the hammering force are not transmitted to the string, so that there is an effect that no live sound is generated in the case of computerization. Moreover, since the rubber pad absorbs the hammering force and can completely mute the live sound, it has an effect that is most suitable for practice at night with the live piano body. Further, since the switches of the number of keyboards are embedded in the rubber pads, the switches can be opened and closed by the operation of the hammer, and the switches are firmly fixed so that they can be used for a long time without damage. There is an effect called.
