[0031] figure 1 is a perspective view of the overall appearance of the first embodiment of the piano of the present invention. This piano is configured as a grand piano 1 including a keyboard having a plurality of keys 2 provided on the front side thereof and operable by a human player for playing, and a sound control pedal 3 . The grand piano 1 further includes a sound generator device 10 having an operation panel 13 on its front surface portion and a touch panel 60 provided on a music stand portion of the piano. A user can input instructions to the sound generator device 10 by operating the operation panel 13 and the touch panel 60 . The piano 1 has functions as a musical instrument equipped with a recording function according to the present invention and as a sound reproduction device according to the present invention.

[0032] The grand piano 1 can be set to a plurality of sound generation modes according to the user's instruction. A plurality of sound generation modes...

[0087] The second embodiment of the invention is generally similar to the first embodiment described above, but the location of the vibration sensor / actuator unit 50 is different. That is, in the second embodiment, each vibration sensor / actuator unit 50 is connected to the bridge 6 instead of the soundboard 7 .

[0088] Figure 8A is a diagram of propagation paths of vibrations during a recording process in which musical composition reproduction data is recorded in string strike mode. Figure 8B is a view of a vibration propagation path during musical composition reproduction processing in which sound is generated via a castanet based on musical composition reproduction data in a string strike prevention mode.

[0089] In response to the depression of any one key 2, the vibration of the string 5-D struck by the corresponding hammer is transmitted from the string 5-D to the bridge 6 (arrow A1r), and then from the bridge 6 to the castanets 7 (arrow A2r) and then audibly emits ...

Abstract

In a musical instrument, such as a piano, having a sound board, the sound board vibrates in response to vibrations of a string responsive to depression of a key. A waveform corresponding to such vibrations of the sound board is detected and recorded. The recorded vibration waveform is usable for reproduction of a sound based on sound board vibrations. In a sound reproduction apparatus, such as a piano, having a sound board, an excitation device physically excitable in response to an input waveform is provided on the sound board. A signal indicative of a vibration waveform of the sound board is received, and the excitation device is driven in accordance with the received waveform signal so that the sound board is vibrated. Thus, a sound based on the sound board vibrations can be replicated or reproduced with a high quality.

Description

technical field [0001] The present invention generally relates to techniques that, in musical instruments provided with castanets (i.e., soundboards) to which physical vibrations of sound-generating members such as strings are transmitted, allow recording of vibration waveforms associated with castanet vibrations , and also relates to a sound reproducing apparatus, such as a musical instrument such as a piano, capable of producing audible sound by vibrating a castanet in accordance with a drive signal representing a waveform of vibration of the castanet. Background technique [0002] Conventionally known pianos are configured to record keyboard performance data and perform automatic performance by driving keys based on the recorded keyboard performance data. In such an automatic player piano, the strings are actually struck by the automatic driving of the keys, and a sound very similar to that produced during keyboard performance recording can be reproduced. If the operatio...
