<P>PROBLEM TO BE SOLVED: To regenerate vibration transmitted to a pedal with a simple configuration, when a key is pressed on an acoustic piano. <P>SOLUTION: An electronic keyboard instrument includes: a key 11; a sound source circuit 64 for generating electronic sound on the basis of operation of the key 11; a pedal device 30 including a pedal 31 supported by a frame 32 to be freely rotated; a vibration device (a first vibration generation device) 20 arranged on the frame 32, which applies vibration to the frame 32; an eccentric weight motor (a second vibration generation device) 25 arranged on the pedal 31, which applies vibration to the pedal 31; and a control section 50 for controlling vibration generated in the pedal device 30. The control section 50 generates a performance signal on the basis of signals from the sound source circuit 64, controls driving of the vibration device 20 according to the generated performance signals, generates key operation information on the basis of a detection signal of a key position sensor 12, and controls driving of the eccentric weight motor 25 according to the generated key operation information. <P>COPYRIGHT: (C)2010,JPO&INPIT |
