Description

Territory of invention

These The invention relates to an acoustic keyboard musical instrument and more particularly to an acoustic piano with a visual display unit.

A typical example of the acoustic piano is in 1 shown. Although not in 1 Shown are hammer actuating mechanisms, hammers, sets of strings and damper mechanisms in a housing 1 added. A string plate 2 , a key bed 3 , an upper beam 5 and a wooden frame (not shown) combine to form the housing 1 , and a clay plate 6 extends horizontally over the wooden frame. The housing 1 has an upper opening above the clay plate 6 , legs 7 stand by leg blocks 8th down in front, on the case 1 are attached. Thus, wear the legs 7 the housing 1 and the other component parts incorporated therein. A keyboard 9 is on the key bed 3 mounted and points to a space between the upper beam 5 and a player. The sets of strings are above the tone plate 6 stretched, and the hammer actuation mechanisms are with the keyboard 9 connected so that they drive the hammers for rotation under the sets of strings.

If a pianist is one of the keyboard keys 9 is depressed, the associated hammer actuating mechanism is actuated, and the associated hammer is driven for rotation. The hammer hits the set of strings and the set of strings vibrates to produce a piano tone. The clay plate 6 produces a resonance with the vibrations and the piano sound is radiated through the upper opening.

A rear upper plate 10 is along one side of the side plate 2 hinged and pivots on the hinges. A front upper plate 11 is along the rear end at the front end of the rear upper plate 10 hinged and swinging on the hinges. If the pianist is the front end of the front top plate 11 raises, the front upper plate rotates 11 around the hinge, and the pianist turns the front top plate 11 on top of the rear top plate 10 , as shown. Then the front parts of the sides can be seen through the front part of the upper opening. If the pianist is the other side of the rear upper plate 10 raises, the rear upper plate rotates 10 around the hinges, and the sets of strings are seen completely through the top opening.

A lid support arrangement 12 is on the other side of the side plate 2 hinged. The rear upper plate 10 becomes in contact with the front end of the lid support assembly 12 brought, and the cover support assembly 12 Holds the rear top plate 12 inclined. When a pianist has a melody on the keyboard 9 he wants to play, he opens the top opening to the piano tones of the clay plate 6 through the upper opening to the outside.

When the pianist leaves the piano, he leaves the rear upper plate 10 on the side plate 2 fall to close the rear of the upper opening, and it pivots the front upper plate 11 to close the front part of the upper opening. The top opening is perfect with the front top plate 11 and the rear upper plate 10 covered. The front upper plate 11 and the rear upper plate 10 protect the hammer actuation mechanisms, hammers, damper mechanisms and sets of strings from dust and unexpected damage. If the pianist has a melody on the keyboard 9 plays without the front / rear upper plates 10 / 11 raise, prevent the front upper plate 11 and the rear upper plate 10 the emission of the piano tones and reduce the volume of the piano tones.

A music stand arrangement 13 is provided over the front part of the upper opening and has a table top 13a , Although in 1 not shown, is a ledge at a lower end of the table top 13a attached. When the tabletop 13a stands up, a player arranges a music book on the table top 13a and the bar prevents the music book from sliding down. The tabletop 13a falls and allows the front upper plate 11 lies on it. Pianists want to express their feelings through the sounds. A pianist may emphasize a lower register, and another pianist may wish to emphasize higher registers or the higher octaves. Accordingly, the pianist strongly presses the keys associated with the lower register or the lower octave or the upper register or the upper octave to express his feelings. The acoustic piano of the prior art speaks faithfully on the fingers on the keyboard 9 and offers the pianist no support.

The music rack arrangement 13 only holds a music sheet or other document lying on it. Notes and letters are written on the sheet music and the documents, and the messages remain unchanged. When a player wants some information, he searches the sheet of music and / or the document for the information. A beginner may wish to review a manual for the piano for his practice. However, it is impossible to have both the No to arrange the operating instructions on the music storage device.

US 3,577,824 discloses a music tutor which generates small illuminated areas on a screen having staves in response to the pressing of keys of an associated musical instrument. The lights are color-coded and positioned to show the music. A movie projector, a lens system and a mirror are arranged to project notes to be played on the same screen.

US Pat. No. 5,864,078 discloses a stand and a flat screen. However, the flat screen is embedded in the stand. In other words, the flat screen is not located immediately adjacent to the stand. It is undesirable for the flat-panel display to be embedded in the stand because the player can obtain information only from the flat-panel display or from a document, such as a music sheet, on the stand.

In the DE 197 43 008 A1 Various arrangements of a display unit are shown. However, a stand is only in the 17 . 18 . 20 . 30 . 31 and 32 shown. In 17 the stand is removed from the display unit by the keyboard; in 18 the display is removed from the stand by a substantial number of black / white keys; according to 20 . 31 and 32 the display unit is vertically spaced from the stand by the piano lid; and according to 30 For example, the display unit is spaced from the stand by a significant number of black / white buttons.

Although the DE 319 825 C teaches that the front cover part is divided into several cover sections, the rear piano cover is still in one piece. The boundaries between the cover portions extend parallel to the longitudinal direction of the keys. On the other hand, the strings are skewed in the piano case of the grand piano. Therefore, the cover portions are not associated with parts or groups of strings, and it is not possible to accentuate or emphasize a particular register by selectively opening and closing the cover portions.

description the preferred embodiments

Comparative example

Regarding 2 In the drawings, a piano has a housing 31 on, a keyboard 32 , Hammer actuation mechanisms 33 , Hammers 34 , Damper mechanisms 35 and sets of strings 36 , The housing 31 is through legs 37 worn, and the keyboard 3 , the hammer actuation mechanisms 33 , the hammers 34 and the damper mechanisms 35 are inside the case 31 assembled. The sets of strings 36 are over the hammers 34 Tense and are each through the hammers 34 struck. In the following description, the term "front" represents a position closer to a player than a "rear" position. The direction between a front position and a corresponding rear position is hereinafter referred to as a "front-to-rear direction", and the term "lateral" indicates a direction perpendicular to the front-to-rear direction. In this case, the lateral direction is perpendicular to the paper, with the piano representing the comparative example as in 1 is drawn.

The housing 31 is the structure of the housing 1 similar to the piano of the prior art. A key bed 41 forms part of the housing 31 , and the keyboard 32 is on the front part of the key bed 41 arranged. A key frame 45 is on the key bed 41 arranged, and a front rail 46 , a balance beam or an operating rail 47 and a rear rail 48 extend laterally parallel to the key frame 45 , White buttons 49 and black keys 50 are with reference to balance or actuation pins 51 rotatable, by the balance beam 47 protrude. The white buttons 49 and the black keys 50 are designed in a well-known pattern. The key frame 45 , the front rail 46 , the balance beam 47 , the rear rail 48 , the white keys 49 , the black buttons 50 and the balance pens 51 Overall, make up the keyboard 32 ,

The hammer actuation mechanisms 33 are equal in number to the white / black keys 49 / 50 and are associated with the white / black keys 49 / 50 connected. actuating bow 52 are on the key bed 41 mounted at intervals, and the hammer actuating mechanisms 33 be from the operating bars 52 carried. The hammers 34 are also from the operating bars 52 carried. The damper mechanisms 35 are at the back of the white / black buttons 49 / 50 intended. A damper lever rail 52 extends laterally, and damper lever flanges 53 are at the damper lever rail 52 appropriate. damper lever 54 are each rotatable from the damper lever flanges 53 worn and are with the rear end portions of the white / black buttons 49 / 50 to engage. damper blocks 55 are with the rear ends of each damper lever 54 connected, and damper wires 56 connect the damper blocks 55 and the damper heads (not shown). The damper heads are from the associated set of strings 36 spaced and are brought into contact with it.

A pianist should use one of the white / black keys 49 / 50 Press down. The white / black button 49 / 50 is moved from the rest position to the end position. The associated hammer actuation mechanism 33 is actuated, and the associated damper lever 54 is pushed up. The damper lever 54 Turn clockwise around the damper lever flange 53 turned, and the damper block 55 and the damper wire 56 spaced the damper head from the associated set of strings 36 , Thus, the damper mechanism allows 35 that the set of strings 36 swings. The depressed white / black button 49 / 50 turns the hammer actuating mechanism 33 in a clockwise direction and escapes the associated hammer 34 , Then the hammer starts 34 a free counterclockwise rotation and beats the associated set of strings 36 at. The set of strings 36 vibrates to create a piano sound. When the pianist presses the depressed black / white button 49 / 50 let go, the depressed white / black key will turn 49 / 50 back to rest position. The rear end part of the black / white button 49 / 50 decreases and allows the damper to return counterclockwise. The damper head will in turn be in contact with the set of strings 36 brought and dampens the vibrations. The hammer actuating mechanism 33 will be back with the hammer 34 engaged.

The 3 . 4 . 5 and 6 show the appearance of the piano, which embodies the comparative example. As previously described, the housing 31 in a similar way to the case 1 built, and a side plate 61 , an upper beam 62 and a wooden frame (not shown) form other parts of the housing 31 , The upper bar 62 is wider than an upper bar of a standard piano, and the lower edge is higher than that of the standard piano. A clay plate 63 extends over the wooden frame, and the set of strings 36 is stretched between suspension pins (not shown) and voice pins (not shown). The bridges 64a / 64b (please refer 2 ) are between the clay plate 63 and the sets of strings 36 introduced to the sets of strings 36 To give tension.

The side plate 61 has a straight part 65 which extends in the direction from front to back. The side plate 61 and the top bar 62 define an upper opening, and a front cover plate 66 and a rear cover plate 67 are intended for the upper opening. The front cover plate 66 is rotatable on both sides thereof with the side plate 61 by means of a pair of pins 68 connected (see 6 ) and is around the pair of pins 68 rotatable as shown by arrow AR1. Thus, the piano implementing the first embodiment has the front cover plate 66 instead of the front upper plate 11 , and the front cover plate 66 gets directly from the side plate 61 carried. When the front cover plate 66 standing up, you can get inside the case 31 through the front part of the upper opening. On the other hand, if the pianist is the front cover plate 66 on a pillow 68b (please refer 7 ) on the upper edge of the upper bar 62 drops, closes the front cover plate 66 the front part of the upper opening. As previously described, the top bar is 62 wider than an upper beam of a standard piano and holds the front cover plate 66 horizontal.

The rear upper plate 67 is in a front lower plate 69 and a rear lower plate 70 split and serves as a kind of equalizer or equalizer. The front lower plate 69 and the rear lower plate 70 are rotatable with the straight part 65 the side plate 61 connected, and cover support arrangements 71 and 72 are on the other side of the side plate 61 hinged. The front lower plate 69 and the rear lower plate 70 stand independently upwards and fall independently on the side plate 61 , The cover support arrangements 71 and 72 hold the front lower plate 69 and the rear lower plate 70 inclined over the middle / rear parts of the upper opening. A pianist can leave both the middle and the back open. However, another pianist covers one of the middle / back parts with the associated front / back bottom plate 69 / 70 from. Thus, the three parts of the upper opening are selectively opened and closed. If the rear upper plate 10 is up, the upper opening is fully opened, as the front upper plate 11 at the rear upper plate 10 hinged. On the other hand, the front cover plate 66 , the front lower plate 69 and the rear lower plate 70 regardless of the side plate 61 worn, and accordingly the pianist gently closes and opens the upper opening. While the pianist makes a sound on the keyboard 32 he plays the front cover plate 66 on the side plate 61 Hold and protect the hammer actuation mechanisms 33 from dust. When the pianist leaves the piano, he leaves both the front cover plate 66 as well as the rear cover plate 67 on the side plate 61 fall, and the front cover plate 66 and the rear cover plate 67 protect the component parts from dust and damage.

As in 4 to see better holds the lid support assembly 71 the front lower plate 69 inclined at a greater angle than that of the rear lower plate 71 , This comes from the fact that the higher notes tend to be more directional or directional than the lower notes. This means that the higher notes or higher register notes are much more likely to be on the lower plate 69 be reflected. The cover support arrangements 71 / 72 regulate the front lower plate 69 and the rear lower plate 70 to suitable angles, in order to compensate for the higher notes with the lower tones chen. The cover support arrangements 71 / 72 can be made advanceable and retractable to change their length. A pianist may adjust an equalizer or equalizer to change the balance between the lower notes and the higher notes by changing the lengths of the lid support assemblies 71 / 72 ,

A music rack arrangement 73 is on the front cover plate 66 appropriate. However, the music rack arrangement becomes 73 out 4 omitted to clear the sub-panels 69 / 70 to show. The music rack arrangement 73 has a tabletop 74 , which is rotatable from the front cover plate 66 will be carried. Some table rail is for the music rack arrangement 73 required, and the manufacturer reduces the number of components. As described above, the front cover plate is 66 horizontally on the side plate 61 and a pianist may record a metronome (not shown) on the front cover plate 66 Arrange.

The front cover plate 66 can by a in 8th shown front cover plate 75 be replaced. The front cover plate 75 has a front part, which is bent from a rear part, and allows the manufacturer to use the upper bar of the standard piano.

The slotted rear top plate 67 selectively emphasizes a higher register or a higher pitch and a lower register or a lower pitch and serves as an equalizer or equalizer. If a pianist wants to produce all the piano tones without any emphasis, he lifts both sub-plates 69 / 70 and ensures that the cover support assemblies 71 / 72 the lower plates 69 / 70 keep inclined over the middle / rear parts of the upper opening, as in the 3 to 6 shown. While the pianist has a melody on the keyboard 32 plays, all the piano tones are radiated through the middle / rear parts of the upper opening, and the split rear upper plate 67 does not emphasize a register.

If the pianist wishes to emphasize a higher register, he leaves the back lower plate 70 on the side plate 61 fall, and the rear part of the upper opening becomes with the rear lower plate 70 covered, as in 9 shown by dashed lines. The front lower plate 69 is open. The Bass Bridge 64b is under the rump of the upper opening. On the other hand, the high bridge extends 64a under the middle / rear parts of the upper opening and is gently curved. The split line 77 between the front lower plate 69 and the rear lower plate 70 crosses the high bridge 64a around the middle of the high bridge 64a at a right angle. The left part of the high bridge 64a on the left side of the crossing point is convex toward the front end of the housing 31 before, and the right part is convex to the rear end of the housing 31 in front.

The set of strings 36 passing the right part of the high bridge 64a and over the Baßbrücke 64b is running, with the rear lower plate 70 covered, and the rear lower plate 70 hinders the radiation of the piano tones in the lower register. For this reason, the piano tones in the lower register are reduced in volume. However, the piano tones in the higher register are radiated through the middle part of the upper opening and are louder than the piano tones in the lower register.

On the other hand, if the pianist wishes to emphasize the lower register, he leaves the front lower plate 69 on the side plate 61 fall and lift the rear lower plate 70 , The cover support arrangement 72 Holds the rear lower plate 70 inclined. As a result, the sets of strings become 36 passing over the left part of the high bridge 64 run, with the front lower plate 69 covered as by the hatching lines in 10 shown, and the other sets of strings 36 are exposed through the rear part of the upper opening. The front lower plate 69 hinders the radiation of the piano tones in the higher register. However, the rear lower plate allows 69 that the other sets of strings 36 emit the piano tones in the lower register without any impedance. As a result, the lower tone is louder than the higher tone, even if the pianist is the same as the black / white key 49 / 50 down, which is assigned to a higher-pitched tone, and the other white / black key 49 / 50 which is assigned to a lower tone, and the lower register is emphasized.

The upper plates 10 / 11 can through the front cover plate 66 and the split top plate 67 be replaced. Then, the prior art piano is transformed into the piano according to the present invention.

Although the lower plates 69 / 70 in the embodiment described above on the straight part 65 hinged, can be a split top plate 78 under plates 79 / 80 have in the up and down direction by means of sliders 81 / 82 is movable on both sides of the lower plates 79 / 80 are attached, as in 11 shown. The gliders 81 / 82 allow a pianist to balance exactly the higher notes and the lower notes. The gliders 81 / 82 move the lower plates 79 / 80 without any inclination. Another glider may be different between the right side and the left side. Project side. In this case, the lower plates 79 / 80 horizontally in the closed positions. However, the lower plates are 79 / 80 inclined in the open positions.

In the comparative example, the hammer actuating mechanisms form 33 and the hammers as a whole several vibration generating mechanisms.

As understood from the foregoing description, the split upper plate realizes 67 the equalizer function by partially covering the upper opening with the lower plates 69 / 70 , and allows a pianist to selectively emphasize the piano tones. If, of course, both sub-panels 69 / 70 open, the piano creates the piano tones without any emphasis similar to the standard piano.

The split top panel is applicable to a mute piano and an automatically playing piano. The silent piano is made on the basis of a piano, and a hammer stopper and an electronic sound generating system are provided in the silent piano. Typical examples of the silent piano are in the US patents US 5,374,775 A and US 5 591 927 A disclosed. The split top plate according to the present invention is further applicable to other acoustic keyboard musical instruments, such as a spinet. In spinet, the vibrational mechanisms pluck selectively at the musical strings.

First embodiment

12 illustrates the inside of a piano embodying the present invention. A housing 200 , Hammer actuation mechanisms 236 , Hammers 237 , Damper mechanisms 238 and sets of strings are similar to those in the comparative example, and a description will be given below only for the important parts.

On a key bed 231 is a key frame 233 arranged, a keyboard 221 wearing. Black / white buttons 234 of which there are 88 are arranged in the lateral direction and are designed in the well-known pattern. The black / white buttons 234 form parts of the keyboard 221 together with a keyframe 233 and scale or actuator pins 235 , The black / white buttons 234 are each about the balance pins 235 rotatable. The black / white buttons 234 stay in the respective rest positions, and 12 shows the black / white buttons 234 in the resting positions. When a pianist uses the black / white buttons 234 presses down, the black / white buttons are sinking 234 and are moved to the end positions. The hammer actuation mechanisms 236 are each with the black / white buttons 234 are associated and are over the buttocks of the black / white buttons 234 arranged. A depressed black / white button 234 operates the associated hammer actuating mechanism 236 , Then the hammer actuating mechanism escapes 236 from the associated hammer 237 and generates a free rotation of the hammer 237 , The hammer hits a set of strings. Then the strings swing so that they produce an acoustic sound.

The damper mechanisms 238 are each with the black / white buttons 234 associated and accordingly with the set of strings. The damper mechanisms 238 are at the rear of the hammer actuation mechanisms 236 located. A damper rail 239 extends laterally along the keyboard 221 , and damper flanges 240 are at the damper rail 239 attached. damper lever 241 are rotatable at their rear ends with the damper flanges 240 connected by respective pins, and the rear end portions of the black / white keys 234 are with the respective front ends of the damper lever 241 to engage. The damper blocks 242 are rotatable with the leading edges of the respective damper levers 241 connected. damper wires 243 stand by the respective damper blocks 242 upward and (not shown) damper heads are at the leading edges of the respective damper wires 243 appropriate.

The depressed black / white button 234 pushes the front end of the associated damper lever 241 upwards and creates a rotation around the damper flange 270 clockwise. The damper block 242 converts the rotation into a straight movement of the damper wire 243 in an up and down direction, and raises the damper head. Thus, the depressed black / white key operates 234 the associated damper mechanism 238 and causes the damper head to leave the set of strings before it hits the strings with the hammer 237 strikes. However, the black / white buttons hold 234 in the rest position, the associated damper heads, in contact with the associated sets of strings, and the damper heads prevent the associated sets of strings from resonating or resonating with the vibrating strings.

With reference to the 13 . 14 . 15 and 16 form a side plate 201 , an upper beam 202 , the key bed 231 and a wooden frame (not shown) in combination with the housing 200 , The side plate 201 and the top bar 202 define an upper opening. The hammer actuation mechanisms 236 , the hammers 237 , the damper mechanisms 238 and the sets of strings are in the case 200 recorded, and a clay plate extends under the set of strings 236 , Although not shown, the sets of strings are stretched between suspension pins and tuning pins, and bridges on the tone plate give the set of strings similar to the standard piano Tension.

The side plate 201 has a straight side part 220a , The top plate 210 is at one end of it at the straight side part 220a suspended, and a cover support assembly 230 is on the other side part of the side plate 201 hinged. A pianist lifts the other end of the top plate 210 and tends the top plate 210 with reference to the side plate 201 , The top plate 201 resting on the leading end of the lid support assembly 230 , and the cover support assembly 230 Holds the top plate 210 inclined. Thus, the pianist puts the inside of the case 220 through a front part of the upper opening to the audience.

A front cover plate 225 is on both sides of it with the side plate 201 by means of pins 226 connected, and is around the pins 226 rotated as indicated by arrow AR11. When a player has a front end of the front cover plate 225 raises, the front cover plate rotates 225 around the pins 226 clockwise, exposing the inside of the case through the front part of the top opening to the audience. The upper opening allows a piano tuner to easily control or adjust the hammer actuating mechanisms and the tuning pins. The pianist leaves the front cover plate 225 on the upper bar 202 fall and cover the front part of the upper opening with the front cover plate 225 , The front cover plate 225 protects the hammer actuation mechanisms 236 , the hammers 237 and the damper mechanisms 238 from dust and damage. The front cover plate 225 is not with the top plate 210 connected, but with the side plate 201 , This feature is desirable for the owner since the owner keeps the front part of the top opening always closed. The upper bar 202 is wider than a top bar of a standard piano. If the pianist the front cover plate 225 on a pillow 203 which drops at the upper edge of the upper beam 202 is attached, sees the front cover plate 225 a horizontally extending flat surface, as in 17 shown. The pianist can place a metronome on the horizontally extending flat surface. Of course, the top bar is 202a the standard piano for the case 200 available. In this case, the front cover plate 225a bent over to the pillow 203 to fall, as in 18 shown.

With reference to the 13 to 16 becomes a music rack arrangement 280 on the flat surface of the front cover plate 225 provided and extends laterally parallel to the keyboard 221 , In this case, the music player arrangement is 280 as long as the keyboard 221 , The music rack arrangement 280 is in a right part 281 and in a left part 282 divided up. A visual display 283 is in the right part 281 installed, and the left part 282 serves as a table or support plate where a music book is placed. In this case, the visual display 283 formed by a liquid crystal display and forms part of an imaging system. The lower end of the right part 281 and the lower end of the left part 282 is rotatable with the front cover plate 225 connected. Although not shown in the figures, the right part is 281 to the left part 282 by means of a connection tied to the backs of the right / left parts 281 / 282 is appropriate. If the connector is the right part 281 and the left part 282 connecting the pianist turns the right part 281 and the left part 282 together. On the other hand, if the connector is the right part 281 from the left part 282 Solves, stand the right part 281 and the left part 282 independent on the front cover plate 225 upwards and lie independently on the front cover plate 225 , As the music rest arrangement 280 rotatable from the front cover plate 225 is not a table rail for the music rack layout 280 required. Thus, it allows the front cover plate 225 that the manufacturer omits certain component parts from the piano, and the production costs are reduced. When the pianist uses the piano for a piano duet, piano notes can be found on both the right and left parts 281 / 282 to be ordered. For this purpose, a bar along the bottom edge of the right part 281 as well as along the lower edge of the left part 282 shaped.

A control box 284 is at a rear side of the front cover plate 225 attached (see 17 ) and is electric with the visual indicator 283 connected by signal lines (not shown). The control box 284 forms another part of the imaging system. A display controller (not shown) is in the control box 284 provided and supplies scanning signals and image-bearing signals to the visual display 283 to display visible images on the screen. The control box 284 allows the manufacturer to see the component parts of the imaging system in the right part 281 to reduce. That's why the right part is 281 so light that a pianist can easily handle it.

The control box 284 is electric with a data processor 285 connected by a suitable interface, and the data processor 285 is further with a chalkboard control device 250 connected through the interface.

The cable 291 in the groove 290 is desirable for a good appearance, so no one sees the cable. In addition, when a pianist steps on a shift or damper or mute pedal, the keypad becomes 244 moved laterally. The cable 291 in the groove 290 is no obstacle against lateral movement.

When the pianist needs information, he operates the switches on the control panel 251 to instruct the imaging system to give it the information. The chalkboard control device 250 interprets the instruction and transfers the instruction to the data processor 285 , The data processor determines visible images, such as characters representing a message / annotation, or a symbol representing the information, and assigns the display driver in the control box 284 to create the visible images on the display. The display driver responds to the instruction from the data processor and supplies the image-bearing signals to the display in synchrony with the scanning signals 283 , Then the visual display generates 283 the visible images on the screen, and the pianist gets the information through the visual display 283 , The information may be musical notes, instructions from a teacher or part of the manual that teaches how to play the piano.

The display can be installed in the left part. A slot 295 can for the control panel 251 be provided. In this case, the slot is 295 in the interior 296 push back with the key bed 231 is formed (see 23 ), and is from the interior 296 to extract (see 24 ). The control panel 251 is at the slot 295 assembled. The inset 295 can be painted with the same color as the key bed 231 , When the control panel 251 the front of the key bed 231 is exposed, the key bed sets 231 a limit to the height of the control panel 251 , The inset 295 however, the manufacturer allows the operator panel 251 free to construct, since the key bed 231 a deep interior 296 offers. When a pianist gives instructions to the data processor 250 through the switches, he presses a button (not shown) and the drawer 295 comes from the interior 296 out. Then the control panel 251 exposed for the pianist. However, the control panel disappears 251 in the key bed 231 , and the appearance of the piano is improved. The pianist can do the inset 295 from the interior 296 pull out manually.

A data processing unit 250 is through a suitable interface with a control panel 251 and the control box 450 connected, and the data processing unit 250 and the control panel 251 form parts of the imaging system 403 , The data processing unit 250 is added to a room inside the key bed 231 is formed, and the control panel 251 shows to the pianist. Thus, only the control panel 251 accessible to the pianist, and the piano according to the present invention has a look like that of the standard piano.

Switch and a cursor control device are on the control panel 251 provided, and a slot is in the control panel 251 educated. A Compact Disc Read Only Memory (CD-ROM) is inserted into the slot and loaded into a CD player. The CD player is also through the interface with the data processing unit 250 connected and transmits digital codes, which transmits the information from the disc to a suitable memory in the data processing unit 250 is provided. The information relates to how the piano is to be used and how to adjust the equalizer or equalizer as described later.

38 illustrates the imaging system 403 , The data processing unit 250 comprises a microprocessor, a program memory, a working memory, an interface and a shared bus which connects the components. The digital codes are transmitted from the disk through the interface to the working memory. The microprocessor periodically checks the operator panel to see if a pianist is operating any of the switches or the cursor control device. When the pianist wants to output messages, he operates the switches on the control panel 251 , Then the imaging system generates 403 sequential pictures on the display 441 , The pictures can represent a succession of questions. The data processing unit 250 has the display control device 450 to create an image that is a list of questions, and the pianist selects one of the questions. Then instructs the data processing unit 250 the ad driver 450 to create an image representing the next list of questions. When the pianist selects one of the next questions, the data processing unit instructs 250 the ad driver 450 to generate an answer to the selected question. In this way, the pianist receives the information from the imaging system 403 , The information required is how to set the equalizer or split top plate. The pianist directs the piano in the desired operating state by communicating with the data processing unit 250 one. Thus, the imaging system serves 403 as an instruction device. The pianist can select the question through a touch panel on the screen of the visual display 441 will be produced. Otherwise, the data processing unit instructs 250 the ad driver 450 to create a cursor on the screen, and periodically checks the operator panel 251 to see if the pianist is moving the cursor or not. When the pianist moves the cursor, the data processing unit points 250 The display driver will move the cursor to the position requested by the pianist. The data processing unit 250 continues to check the control panel 251 to see if the pianist selects a question displayed by the cursor. When the pianist confirms the question, the processing unit proceeds 250 to the next step ahead. The questions are arranged in a hierarchy. Of course, the questions can be put in a list.

The pianist will probably request information regarding the accentuation of a register or pitch. If the pianist has a list of questions from the data processing unit 250 requests, instructs the data processing unit 250 the ad driver 450 to create images that display the list of questions on the display 441 pose as in 39 shown. It is assumed that the pianist moves the cursor C to the first question "how to emphasize higher notes".

When the pianist confirms that the cursor C indicates the question he has, the data processing unit instructs 250 the ad driver 450 on, pictures on the display 441 to produce, as in 40 shown. The image represents the piano, with the front lower plate 421 and the rear lower plate 422 are opened and closed accordingly, and a description is given as "close rear lower plate. Although the pianist is a beginner, he can understand from the image of the piano how to adjust the equalizer or split top plate.

The pianist lifts the front lower plate 421 , and he holds it by means of the lid support assembly 423 inclined, as in 41 shown. The pianist leaves the back lower plate 422 closed. The front lower plate 421 emits the higher notes, and the lower back plate 422 prevents the radiation of the lower notes. As a result, the higher notes are emphasized. The division line between the sub-panels 421 and 422 crosses the high bridge 64a around its center at a right angle. The center almost divides the high bridge 64a in the left part and the right part, and the left part is curved convexly towards the pianist who is sitting on a chair in front of the keyboard 401 sitting.

Sensors may be in association with the sub-plates 421 / 422 be provided. In this case, the sensors have the data processing unit 250 about the current status of the shared top panel 420 informed. The data processing unit 250 has the ad driver 450 to successively generate images representing the required operation. The moving pictures let the pianist understand exactly how to adjust the equalizer or equalizer. The data processing unit 250 may instruct the display driver to display characters that represent the names of the parts, such as "front sub-plate" and "rear sub-plate," next to the image of the piano.

On the other hand, it is assumed that the pianist moves the cursor to the second question "How to emphasize lower notes". When the pianist confirms that the cursor indicates the question he has, the data processing unit instructs 250 the display driver, images on the display 441 to produce, as in 42 shown. The image of the piano shows the front lower plate 421 and the rear lower plate 422 which are closed and opened, respectively, and the messages are, for example, "close front lower plate, open lower rear plate".

The pianist opens the back lower plate 422 and close the front lower plate 421 according to the notes (see 43 ). The closed lower plate 421 prevents the radiation of the higher notes. However, the rear lower plate allows 422 in that the pages radiate the lower notes to the audience. As a consequence, the lower notes are emphasized.

When the pianist requests an answer to the question of how he lowers the volume of all sounds, the data processing unit instructs 250 the display driver, an image of the piano with closed sub-panels 421 / 422 and a message such as "close both sub-panels".

Although the split top plate 420 is not common for pianists, the pianist receives the information from the visual display 441 and easily sets the piano in a desired accenting state.

The data processing unit 250 continues to address the question of how the pianist plays the piano. The request may relate to the damper pedal. The data processing unit 250 has the ad driver 450 to create an image of the piano, with the damper pedal shown with an arrow, and notes on instructing about an effect that is impressed on the piano tones.

Sixth embodiment

Regarding 44 In the drawings, a silent piano based on the piano is embodied, which embodies the fifth embodiment. The dumb piano has a split top panel 420 and the imaging system 403 , For this reason, the component parts corresponding to those of the fifth embodiment will be denoted by the same reference numerals without detailed description.

The silent piano also has a mute system and an electronic tone generation system 480 on. The mute system or mute system has a hammer stopper 470 on, which extends laterally over the hammer shanks, further a pedal and a link mechanism. The hammer stopper 470 is with the pedal (see 45 ), and is switched between a free position and a blocking position. Accordingly, the mute. Piano selectively set to an operating state with acoustic sound and a mute operating state. During the hammer stopper 470 remains in the free position, beat the hammers 237 the associated sets of strings. However, if the pianist is the hammer stopper 470 Switches into the blocking position, bounce the hammer 237 on the hammer stopper 470 before they strike the strings, and some piano tone is produced by the strings.

The electronic sound generating system 480 has key sensors 481 on, each with the black / white buttons 234 are associated. Each of the key sensors 481 is by a combination of a shutter or interrupter plate 482 and a photocoupler 483 set up. The breaker plate 482 is at the bottom of the associated black / white button 234 attached, and the photocoupler 483 emits a beam of light over the path of the associated black / white button 234 from. If the pianist selectively a black / white button 234 depresses, interrupts the breaker plate 482 the light beam and gradually reduces the size of the photo or luminous flux in the photocoupler 483 is produced. The photo or luminous flux is converted to a potential, and the potential varies depending on the current key position. Thus, the key sensors monitor 481 the associated black / white buttons 234 and generate key position signals representing the current key position.

The electronic sound generating system 480 further comprises a control device 490 and a headphone 492 on. The control device 490 is from the electronic sound generating system 480 and the imaging system 403 divided. For this reason, the switches are for the electronic sound generating system 480 on a control panel 494 along with the switches and slot for the imaging system 403 intended.

The control device 490 works similarly for the data processing unit 250 and has the ad driver 450 to create pictures. In this case, the control device is feeling 490 the interface to see if any of the black / white buttons 234 the current key position changes and determines the key code of each depressed black / white key 234 assigned. Furthermore, the control device calculates 490 the key velocity for each depressed black / white key 234 and decides a timing for generating an electronic sound and a timing for removing the electronic sound. The control device 490 has a tone generator, and the tone generator generates an audible signal from the music data pieces. The audible signal goes to the headphones 492 delivered, and the headphones 492 generates an electronic sound.

In this case, the imaging system teaches 403 the pianist, how to play a melody without pianotones. When the pianist uses the imaging system 403 requesting to teach how it switches the silent piano in the silent mode, the control device 490 the ad driver 450 to create images as in 45 shown. An image of a dumb piano is accompanied by an arrow indicating the right pedal. A message says "Step on the right pedal". The right pedal is with the hammer stopper 470 connected.
