摘要： According to which a damper is operated before or after keying, one of two resonances is generated. A second waveform storage (18) storing original waveform data of a first resonance based on a music sound including an impact sound of keying according to a before-key-pressing pedaling, and a third waveform storage (19) storing original waveform data of a second resonance based on a music sound which does not include an impact sound of keying according to an after-key-pressing pedaling, are provided. A switch (20) is switched according to the state of the pedal at the time of key pressing to supply selected resonance waveform data to a resonance generating unit (16). The resonance signal outputted from the resonance generating unit (16) and a music sound signal of a direct sound of keying are added by an adder (24) and inputted into a sound system.

摘要： The vibrating function of an acoustic transducer with respect to a vibrated body to be vibrated is maintained even when the vibrated body undergoes a dimensional change in a direction intersecting a vibration direction in which a movable unit vibrates. The movable unit 100 of the acoustic transducer 50 includes an electromagnetic coupling portion EM and a rod member 101. When a drive signal is input to a voice coil 513, the electromagnetic coupling portion is driven by a magnetic-path forming portion 52 forming a magnetic path, so that the movable unit vibrates in a Z direction. A second-end-portion connector 110 connects a second end portion 101b of the rod member 101 fixedly to a soundboard 7, so as to transmit vibration of the movable unit to the soundboard 7. A displacement permitting mechanism is provided at at least one of: an attachment portion which attaches the magnetic-path forming portion 52 to a back post 9; the movable unit 100; and the second-end-portion connector 110, whereby electromagnetic coupling between the magnetic-path forming portion 52 and the electromagnetic coupling portion EM is maintained and the vibration of the movable unit 100 is transmitted to the soundboard 7 even when the second-end-portion connector 110 is displaced with respect to the back post 9 within a predetermined range in the horizontal direction.

摘要： An efficient digital waveguide synthesizer is disclosed for simulating the tones produced by a non-linearly excited vibrational element coupled to a resonator, such as in a piano. In a preferred embodiment, the synthesizer creates an excitation pulse from a table containing the impulse response of a piano sound board and enclosure. Alternately, this excitation pulse can be synthesized by filtering white noise. The excitation pulse is fed into the filter that simulates the collision of the piano hammer and string. Because the hammer-string interaction is nonlinear, the characteristics of this filter vary with the amplitude of the tone produced. The filtered excitation pulse is then fed into a filtered delay line loop which models the vibration of a piano string. Because the excitation pulse already contains effects of the resonator, the tone produced by the delay line loop does not require additional filtering in order to model the resonator.

摘要： A musical tone synthesizing apparatus synthesizes musical tones by simulating the tone generation construction of a plucked-string or struck-string instrument. The apparatus has a loop circuit (8) which simulates a vibrating element of the instrument, an excitation circuit (14) creates an excitation signal corresponding to the excitation given to the vibrating element in response to the operation of operators such as a pick or a hammer or the state of the generation body and a memory which stores a non-linear relation between the operator and the vibration element. The excitation signal circulates around the loop circuit (8) and is delayed by means of a delay circuit (1,5) with a previously determined delay interval, and is fed back into the excitation circuit (14) as the state of the vibrating element. To realize a variety of sounds depending upon characteristics of the operator, such as the shape and hardness of the pick or the hardness of the hammer, a readout value of the memory, which is read out according to such characteristics, is supplied to the loop circuit.
