CONSTITUTION:When a key of a keyboard part 205 as the playing operation element is pressed down, the keyboard part 20 outputs the musical tone information. And, the sound source part 150 outputs a musical tone according to the inputted musical tone information, and the musical tone outputted from the sound source part 150 is acoustically radiated by an amplifier 100 and a loudspeaker 120. The output musical tone of the sound part 150, on the other hand, after being amplified by an amplifier 101 is outputted to an actuator 300, which starts vibrating according to the input amplified musical tone signal. In this case, the actuator 300 is fixed to the keyboard part 205, so the keyboard part 205 vibrates together with the actuator 300.

First, when a key of the keyboard unit 205, which is a performance operator, is depressed, the keyboard unit 205 outputs musical tone information in the same manner as in the conventional example. The sound source section 150 outputs a musical tone according to the inputted musical tone information. The musical sound output from the sound source unit 150 is acoustically radiated by the amplifier 100 and the speaker 120 as in the conventional example.

On the other hand, the musical sound output from the sound source section 150 is amplified by the amplifier 101 and then output to the actuator 300. The actuator 300 starts vibrating according to the amplified musical tone signal that is input.
Since the actuator 300 is fixed to the keyboard unit 205, the keyboard unit 205 vibrates together with the actuator 300.

As described above, according to the first embodiment, the tone generator 150 outputs a tone corresponding to the tone information output from the performance operator (keyboard 205). Actuator 300 fixed to the performance operator (keyboard 205)
Since it is adapted to vibrate in accordance with the musical tone signal amplified by the amplifier 101, the performance operator (keyboard part 205) also vibrates.

The musical sound output from 50 is the amplifier 100 and the speaker 1.
By 20, the musical sound is radiated acoustically as in the conventional example.

On the other hand, the output of the sound source section 150 is amplified by the amplifier 101 after removing the high frequency components in the low pass filter 170. Amplifier 101
Is input to the actuator 300, and the actuator 300 vibrates. Since the actuator 300 is fixed to the operating element 200, the operating element 200 and the mouthpiece 210 also vibrate together with the actuator 300.

In the so-called saxophone type mouthpiece which holds the mouthpiece 210 as shown in FIG. 2, by vibrating in the AB direction of FIG. . For this reason, the actuator 300 is fixed to the operating element 200 so that the vibration direction thereof is the AB direction in FIG. Further, since the high frequency component of the musical sound is difficult to work as a component for directly vibrating the pipe in the wind instrument, the low pass filter 170 removes the component of 4 kHz or more, so that the actuator 300 is similar to the wind instrument. Vibration will be applied to the operator 200.

The cut-off frequency of the low-pass filter 170 does not have to be fixed at 4 kHz, but may be set according to the kind of musical sound to be output or the player's preference.

As described above, according to the second embodiment, the low-pass filter 170 removes the high-frequency component of the output of the sound source section 150, so that the actuator 300, the manipulator 200, and the mouse are removed. The vibration of the piece 210 is the same as that of the acoustic musical instrument, and the playing feeling can be felt very realistically.

Vibrate to.

On the other hand, the musical sound output from the sound source section 150 is amplified by the amplifier 102 and is then transmitted to the actuator 3
01 is vibrated, so that the operator 202 and the mouthpiece 2
11 will vibrate in the DE direction in FIG.

The vibration in the AB direction is applied to the player's lips, and D
Since the vibration in the E direction is easily felt by the fingertips of the player, the desired vibration state can be created by adjusting the volume of the amplifier 101 and the amplifier 102.

In the fourth embodiment, the operator 2
Although the configuration of No. 02 is a wind instrument configuration, it should be added that the same effect can be achieved even with a guitar-shaped operator, for example.
