Description of the Invention: [Technical Field] The present invention relates to a keyboard-playing musical instrument having a bene mechanism that continuously changes a pitch. [Prior Art] Since the interval (that is, the height of the interval) is basically determined by each reed (the natural frequency of the ree sentence, the keyboard is playing the instrument - it is considered to be a kind of performance that cannot be continuously changed, and the portamento cannot be obtained. Musical instruments. Recently, there have been proposals to continuously change the pitch of the instrument by adding a tremolo mechanism. One of the cases is disclosed in Japanese Unexamined Japanese Patent Publication No. 9(6) (paragraph [_8]~[00! 8], and reference drawings. 2) Further, since the above-described vibrato mechanism does not search for various databases, the prior art documents which are closely related to the present invention cannot be found except for the above-mentioned gazette, and thus the above-mentioned gazette is positioned as the prior art of the present invention. The keyboard-playing musical instrument described in the bulletin is provided with a plug valve having a small hole between the air outlet portion of the flute chamber and the flap valve (ree "alve"). The pressure between the two ends to close the outlet of the working gas in the flute moon. Once the reed valve is pressed with the key press of the keyboard, the reversal of the plug valve is released. The plug valve also opens the air outlet portion of the flute due to the force of the compression spring piece and the reed valve _ body. The denier valve opens the air outlet portion, and the air spring reed vibrates according to the current air flow reed.

However, the above-mentioned previous keyboard blowing is very popular. In order to set up two valves for each flute, the number of complicated parts is increased. - Again, because it is necessary to use the sealing member to connect the exit line of the flute The gap between the earth valve and the gap between the I-plate valve and the plug valve is sealed, and the gap of the above-mentioned gap occurs when the sealing performance is lowered due to the deterioration of the sealing member. And the problem of performance degradation as a musical instrument appears. In addition, since the plug valve must be assembled in the narrow portion between the air outlet portion of the flute chamber and the flap valve, the assembly work efficiency during the manufacture of the musical instrument is reduced. There is a problem that the keyboard and the flap valve must be removed from the frame when the plug valve is re-adjusted or repaired, otherwise the problem will not be solved. SUMMARY OF THE INVENTION The present invention is to solve the above problems of the prior art. The object of the present invention is to provide a keyboard-playing musical instrument having the following features; the use of a so-called single-valve method can attempt to simplify the structure and reduce the number of parts, and can ensure the improvement of assembly work efficiency and re-adjustment and repair work. Simplicity 'can achieve good vibrato effects. The keyboard-playing musical instrument associated with the present invention has a plurality of flute chambers, and the 91251.doc 1300919 is formed by juxtaposing the partition walls in parallel; the air chamber is interposed between the reed holes and each of the flute chambers and communicates with the mouthpiece a reed, a reed hole disposed in each of the above-mentioned flute chambers; a plurality of reed valves opening and closing an air outlet portion of the flute chamber which is not integrated with a keyboard composed of a plurality of keys; and a vibrato mechanism, closing Press the above reed valve in the direction. According to the above configuration, when the cymbal valve is opened, since the tremolo mechanism reed valve is pressed toward the closing direction, the air flow of the I-piece valve rotating outward from the air outlet portion of the flute is reduced, so the vibration of the reed changes. Therefore, it is possible to obtain a vibrato effect with a lower interval than normal. The above-mentioned sound mechanism is composed of the following materials: _Gu, in order to correspond to all the juxtaposed reed valves that are freely rotated behind the reed valve; the operation means, the above-mentioned intervening The body is rotated in the direction of the cyanite; the force applying means is to restore the valve pressing body to the initial position; and the braking member 'limits the rotation angle of the valve pressing body. Therefore, the vibrato mechanism is simple and clean | 彳μ 〇苒 (construction & premature, and can make the dog sturdy and rotate. The part, which is in the vibrato mechanism, does not work as a brake ^ Connected from all open The state of the spring body obstruction of the heart between the shells and the detachment of the knife period to go · a brake part, in the vibrato #, brother one in the second gas outlet is not closed, the sheet valve Β ±, ^, and & When the closing direction is rotated and the returning ceremony is performed, the valve body is stopped at the rotating position. And according to the above configuration, the vibrator portion is started to be in contact, so that the second pair of the reeds are rotated, so the reed valve does not The 9125I.doc 1300919 air outlet is completely closed. Therefore, the state of the yellow sheet is not shown. According to the above, the present invention can achieve a simple structure and a reduction in the number of parts by using a single valve method. It is possible to improve the workability of the assembly and to ensure the ease of work such as re-adjustment and repair. Therefore, a good vibrato effect is obtained. [Embodiment] Reference will be made to the additional drawings below.

In the above figures, the same symbols are used to reveal the corresponding parts, symbols The machine indicates that the keyboard is playing the whole instrument, and the symbol 2 indicates the instrument box that constitutes the resonance box. The instrument box 2 is assembled as follows: a shallow bottom box type that is opened upwards, in the instrument box The inner air chamber forming member 4 and the frame (the flute forming member) 3 having the mouthpiece 5 cover the opening portion on the upper side of the instrument case 2. 91251.doc -10- 1300919 frame: synthetic tree wax The molded article is internally formed by a plurality of spaced apart flutes 8 corresponding to each of the specified intervals to the frame 3; the alignment formed by the above-described flute 8 is formed to the back of the frame 3. The lower side of the side is open, and the opening portion of the back side is formed to open the air outlet portion 9 to the inside of the instrument case 2, and the lower portion of the opening portion 1 is covered by the cymbal plate. The yellow plate 11 has all the flutes The cavities 8 are extended together by a length, and at the same time, a plurality of elongate plurality of cymbal holes 12 formed corresponding to the respective flute chambers 8, through which the flute chamber 8 is in communication with (hereinafter referred to as (b) the air chamber 14 series. Further, a plurality of reeds 13 are attached to each of the reed holes 12 on the lower side of the reed plate u. The mother piece 13 is composed of a rectangular thin metal piece having a specified length and natural frequency. The base end portion is fixed by the spot welding or the rivet or the like under the above-mentioned chopping board 11, and therefore, each of the reeds 13 are supported by the overhanging shoulders. Therefore, the air blown from the mouthpiece 5 flows into the chamber 8 through the air chamber 14 to the reed hole 12'. The free end side of the sheet 13 vibrates due to the air flow at this time. The reed hole 12 emits a sound of a specified interval by forming intermittent air due to the vibration period _ of the reed 13. It is detachably attached to the connecting hole 丨 5 (see Fig. 4) provided on the player's side, that is, the left side of the frame 3 at the time of performance, and protrudes toward the outer surface of the instrument case 2. The air chamber forming member 4 is fixed to the lower end portion of the frame 3 so as to cover the reed plate 11 and the reed i 3, and the air chamber 14 is formed by the space surrounded by the air chamber forming member 4 and the frame 3. . The air chamber 14 communicates with the plurality of flutes 8 through the reed holes 12 while communicating the mouthpieces 5 through the connecting holes 15. A sub air chamber 8 is formed at a portion above the flute chamber 8 of the frame 3. The sub-space 91251.doc -11- 1300919 = two chambers 18a, 18b, 18e having a specified order by the partition wall 19 in the longer direction of the frame 3. These cavities 18 (10) and the communication holes 20 formed in the partition wall 6 of the flute chamber 8 communicate with the air chamber 14, so that the volume of the air chamber 14 is enlarged on the apricot. By setting the secondary air cavity, the natural frequency of the air in the air chamber 14 is moved to the point where it is not affected by the bud (4), in other words, the natural frequency of the air in the air chamber 14 can be set to be one piece 13 The natural frequency is about small. Therefore, the resonance of the reed η is not caused by the vibration of the reed η, and the so-called blowing stopper is not generated in both the air chamber 14 and the sub air chamber 18, and in the wide sound π from the bass to the treble The pronunciation is averaged in volume, so that it can perform stable performance. The frame 3 is composed of a white key 22A and a black key 22B. For example, a keyboard 22 composed of 37 keys is disposed in parallel in the longer direction of the instrument case 2.

It is allowed to swing freely up and down, and the tension spring 24 is attached to the directional returning direction (clockwise direction of FIG. 3). Further, a plurality of reed valves 25 are provided near the lower end portion of the white key 22A and the black key 22B, each of which is integrally disposed vertically. The reed valve 25 is normally pressed from the rear by facing the back surface of the frame 3 by the compression spring 24, and the air outlet portion 9 of each of the flutes 8 is closed to maintain the initial position of each key. The frame 3 is provided with a tremolo mechanism 30. The purpose of the vibrato mechanism 30 is to obtain a vibrato effect which rotates the reed 25 in the closing direction by the keyboard operation during the range in which the air outlet portion 9 is not completely closed by the keyboard operation. The required angle is 91251.doc -12-1300919 degrees. Temporarily reduce the interval of pronunciation. The vibrato mechanism 30 is composed of the following components: a pressing body 31 which is rotatably disposed behind the frame 3, and a length corresponding to all of the reed valves 25; and an operating means 32 for causing the above-mentioned valve The pressing body 31 is rotated in the direction of the reed valve 25; the force applying section 33 is for returning the valve pressing body 31 to the initial position; and the pair of braking members is for restricting the rotation of the valve pressing body 3 1 Angle. In Fig. 3 and Fig. 7 or Fig. 9, the valve pressing body 31 is composed of three types of five connecting rods: a parallel rotating shaft 35 and a connection located behind the reed valve 25 (i.e., the open side of the reed valve 25). a connecting rod 37 connecting the rotating shaft 35 and the vicinity of the two ends of the connecting rod 36; the connecting rod % connecting the middle portion of the rotating shaft 35 and the connecting rod 36; and the connecting rod 39, which is connected to the middle portion of the rotating shaft 35 and the connecting rod %.

The guide block 4〇 (refer to FIG. 3) of the lower end portion of the lower end portion of the third portion is formed with a pressing portion 32 of the pressing connecting rod 39 at the front end portion thereof, and is provided with 91251.doc -13-1300919 at the rear end portion thereof. The knob portion 32B protrudes outward from the insertion hole 43 provided at the lower portion of the rear surface of the instrument case 2. On the lower surface side of the connecting rod 39, a triangular projection 39A pressed by the pressing portion 32A of the operating means 32 is integrally protruded. The above-mentioned force means 33 The right and left integral torsion bar is arranged in parallel with the rotating shaft 35, and each outer end is hung on the engaging portion 38A provided on the connecting rod 38, and the inner end is press-fitted and fixed to the supporting body 41. The hole applying means 33. When the vibrating mechanism 3 is in the inoperative state, the pressing means 33 has little effect on the pressing body 31, and once the tremolo mechanism 3 is started, the valve is rotated clockwise as shown in FIG. When the pressing body 3 1 is tightened # Φ, the force is accumulated by returning the valve pressing body 3 1 to the initial position. Further, as the biasing means 33, the torsion bar is not limited to the torsion bar. The bodies 41 are respectively fixed to the lower surface of the frame 3 by screws, and have a U-shaped groove 46 for holding the rotating shaft 35. The purpose of the above-mentioned braking member 34 is to limit the rotation angle of the valve pressing body 3, and is fixed by screws. Each of the left and right end portions of the frame 3 has a respective designated position. Each of the brake members 34 is composed of the following members: a socket 48 which is a shaft for rotating freely holding the above-mentioned rotating shaft 35; and a first and a second brake member portion "A" And, the system regulates the connecting rod 37 to rotateThe first and second brake member portions 50A and the inclined surface are formed by the stoppers 34 such that the two projection portions 51A and 51B projecting from the inner surface opposed to the connecting rod 37 are juxtaposed in parallel with each other. That is, when the brake member 34 is screwed to the lower rear end portion of the frame 3, the above-described brake member portions 5A and 5B constitute a slope in which the holding angle is inclined forward as shown in Figs. 7 and 8 Usually, the first brake member 5GA catches the connecting rod 37 and connects it to the initial position 91251.doc -14-1300919 (refer to, in this state, even if the maximum angle of the open reed valve 25 is operated by the key) The reed valve 25 is also not connected to the connecting rod ^. The second brake member. The P-position 5GB is limited by the rotation angle of the tweezers (4) 3 when the tremolo mechanism 3G is started. In the range in which the air outlet portion 9 is not completely closed, the required angle is rotated back in the closing direction. In addition, the left and right-to-the-brain members are formed in a bilaterally symmetrical shape, and inserted between the projection portions Μ and 5ΐβ to rotate the connecting rod 37 within a desired angle. It is possible that when the keyboard is composed of the above structure and the musical instrument is not played, the force of the flap valve (4) over the tension spring 24 is connected to the back of the frame 3 to block the air outlet of the brake member 9. In this state, the blow is blown. Mouth 5 blows air because the air outlet Bit 9_, the air does not flow, the crystal piece speaks vibration. On the other hand, blowing from the mouthpiece 5 and pressing the button to operate any white key 22A and the black button corresponds! The sheet valve 25 will open, open the corresponding reed valve The empty milk outlet portion of the flute chamber 9 of the flute chamber 9 is opened. After the air outlet portion 9 is opened, the air entering the air chamber 14 by the blow nozzle $ is flowed through the reed hole 2 into the flute chamber 8 corresponding to the key of the press key operation. The reed 13 of the flute chamber 8 is vibrated, and then discharged from the air outlet portion 9 into the instrument case 2, so that the sound of the normal interval is emitted. When the above-mentioned 4/Bee is sad, the operator operates the operation by hand. Operation of 3 2. P bit 32B ' Therefore, after the operation means 32 is pushed into the instrument case 2, the pressing portion 32A of the smashing means 32 presses the protruding portion of the connecting rod 39, so the valve pressing body 3 1 is oriented in Fig. 8 Rotating in the counterclockwise direction, the connecting rod 36 presses the reed valve 25 in the fully open state from the rear. Therefore, the flap valve 25 is rotated in the closing direction by the required angle so that the air outlet portion 9 is in an open state of one-and-a-half or less of the full opening. The opening area of the outlet part 9 is squeezed 91251.doc -15· 1300919 Therefore, the spring

The slice 13 is capable of emitting a lower interval than usual. Because of the tremolo effect caused by the addition of the usual sound strength or sharpness, the pressure is reversed. After the pressing state of the operating means 32 is released, the restoring force of the lever member 33 of the lever member 33 is rotated back to the first brake member portion 50A, thereby releasing the reed state of the reed valve. Thereby, the reed valve 25 also returns to the fully open state, and the state of the reed 阙 13 can be returned to the normal sound state. Moreover, the above-described embodiments disclose an application example for a keyboard-playing musical instrument in which the sub air chamber 18 is provided to the frame 3.
