d. Shaft and Operator For example, as shown in FIGS. 4 (A) and (B), a short square-shaped slider case 112 is attached to the outer surface of the shaft 108 having a rectangular cylindrical shape. In addition, a slider 130 for supporting the roller 128 is inserted on the inner surface side. The slider 130 faces the upper surface of the shaft portion 108 through a slit portion 132 formed in the shaft portion 108, and is fixed to the slider case 112 using fixing screws 134 as fixing means. On both intermediate sides of the slider 130, plate-shaped spring fixing portions 136, 13

When the 30 is moved, the roller 128 moves together with the slider 130, and a resistance value representing the sliding position is obtained in the touch volume 220. This is the interval specified data D _d.

e. Description of operation The operation of the above configuration will be described.

The player grasps the grip 104 with his left hand, for example, and turns his thumb with the switch button 600 of the key changeover switch 60.
, And grips the grip portion 114 of the slider case 112 with the right hand. At the same time, the player puts the lips on the mouthpiece 102 and vibrates the lips by the action of the exhalation pressure.

Grip the grip portion 114 of the operating element 20, moving the slider 130 on the shaft portion 108, the pitch corresponding to the position is specified by pitch specifying data D _d is obtained, at the same time, added player is through the mouthpiece 102 Due to the vibration of the lips, a resonance sound corresponding to the vibration is generated in the resonance tube 50, and the pitch data D _f
Is obtained.

Further, the volume level of the resonance sound obtained through the resonance tube 50 changes according to the exhalation pressure applied to the mouthpiece 102 by the player, and the volume information _DV is obtained from the volume information detection unit 58.

Therefore, the musical tone control unit 30 receives the pitch designation data D _d determined on the operator 20 side and the pitch information detection unit through the resonance tube 50.
Pitch data D _f obtained from 56, was added the volume data D _V from the volume information detecting unit 58, the sound volume data D _V in pitch set by the high and low frequencies with the volume specified data D _d and the pitch data D _f tone data D _O representing the tone of the determined volume is obtained. When the tone data D _O is added from the tone control unit 30 to the tone generator 32, the pitch from the tone generator 32, tone signal V _M corresponding to the element volume, and the addition to the sound system 34 are read. As a result, a musical tone having a pitch selected by the player and having a required level is generated.

When the pitch of this musical tone is designated, the slider 130 is placed farthest from the grip 104 and the lips of the mouthpiece 102 are vibrated. In the case of), as shown in FIG. 5, when the pitch of C is designated, and when the slider 130 is moved stepwise so as to approach from the far side of the grip 104, a second harmonic is applied to the resonance tube 50, As shown in FIG. 5, the pitches of C ^{# to} G are designated according to the position of the slider 130 stepwise. In addition, grip the slider 130 with the grip 104
When a third overtone is applied to the resonance tube 50 while moving the resonator in a stepwise manner so as to approach from a distance, as shown in FIG.
The pitches of G ^{# to} C are designated according to the position of the slider 130 stepwise.

In this manner, the pitch is specified by the stepwise movement of the slider 130, and the player intentionally modulates the lip vibration to make the resonance sound acting on the resonance tube 50 1-8 harmonics, thereby achieving the operation. The pitch specified by the child 20 is switched to another pitch depending on the pitch of the resonance sound. Therefore, a desired pitch is obtained according to the position of the slider 130 and the vibration of the lips. In the example shown in FIG. 5, the position of the slider 130 is changed, and the operation of the 1-8 harmonics obtained by the resonance tube 50 is performed. As a result, a pitch change of two octaves or more is obtained.

Also, by adjusting the expiration pressure applied to the mouthpiece 102 by the player, the level of the resonance sound generated in the resonance tube 50 can be increased or decreased, and the musical sound can be generated at an arbitrary volume level.

Then, the slider 130 of the operator 20 with respect to the pitch change amount
If the positional movement amount is set to be large in the low harmonic range and small in the high harmonic range, the operation mode is the same as that of the trombone of the natural musical instrument, and the operability similar to that of the trombone is obtained.

When the touch volume 220 is used for the position sensor 22 as in this embodiment, the wear can be reduced and the durability can be improved as compared with the slide type variable resistance, and the reliability of the designation of the pitch can be improved.

If the key change of the key change switch 60 is added to the pitch change caused by the movement of the slider 130, the electronic musical instrument described in the embodiment can be made to function as a wind instrument with a wider range of pitch change. , For example, from tube F to B
It can be used as a ^b- tube.

f. Other Embodiments In the electronic wind instrument of the present invention, for example, as shown in FIG. 6, locking means for locking the slider 130 to the substrate 222 installed inside the shaft portion 108 in accordance with the pitch. Alternatively, a click portion 228 formed of a concave portion may be formed, and the slider 130 may be locked in a stepwise manner corresponding to the pitch.
In this case, when the slider 130 is moved, the roller 128 falls into the arc-shaped click portion 228 corresponding to the roller 128, and a force larger than a flat portion is required to pass through the click portion 228. Therefore, when the player moves the grip portion 114, the player can feel the state in which the roller 128 falls into the click portion 228, and can specify the pitch mechanically with high accuracy, and can specify the pitch of the trombone as a natural musical instrument. Ambiguity is improved.

In the case of this embodiment, the click portion 228 is
However, it may be formed on the inner wall of the shaft portion.

In each embodiment, the data obtained by the vibration sensor 22 can be used for floating data processing in which a change in the pressure-sensitive level is added to data of an initial value. , Can be used as pitch bend data for imparting effects such as vibrato and slur on musical tones.

In the embodiment, the vibration sensor 22 that converts pressure into an electric signal has been described as an example.
As the 22, any one that can be detected by a change in inductance according to the resonance sound of the resonance tube 50 can be used. Also,
The resonance frequency may be changed by changing the length of the resonance tube 50. In addition, pitch switching
The frequency is not limited to every overtone, but may be every 5 degrees.
