Abstract: A vibration detection mechanism includes: a first sensor section that detects vibration of a vibrating member of a musical instrument in a first direction being a main vibration direction; a second sensor section that detects vibration of the vibrating member in a second direction being approximately perpendicular to the first direction; and a third sensor section that detects vibration of the vibrating member in a third direction being approximately perpendicular to both the first direction and the second direction. Sensitivity of the second sensor section is greater than sensitivity of the first sensor section. Sensitivity of the third sensor section is greater than the sensitivity of the first sensor section.

Abstract: A computer-implemented reproduction control method includes reproducing sound from sound data representing a series of sounds including first sound and second sound that follows the first sound. The method includes starting reproducing the first sound, continuing the reproduction of a first sound until an end of the first sound in response to receiving a first instruction in a reproduction period of the first sound, stopping the reproduction of the first sound, and after the stopping of the reproduction of the first sound, starting reproducing the second sound in response to receiving a second instruction provided by a user.

Abstract: A sound processing method includes: receiving, using the communication device, from the remote apparatus, a first sound signal representing first sound generated by a user of the remote apparatus; emitting, using the sound emitting apparatus, the first sound represented by the first sound signal; receiving, using the sound receiving apparatus, sound that includes second sound generated by a user of the sound processing system; generating a second sound signal by sound processing, using processing parameters, a reception sound signal generated by the sound receiving apparatus; transmitting, using the communication device, the second sound signal to the remote apparatus; updating the processing parameters based on the first sound signal or the reception sound signal; and stopping the updating of the processing parameters in a state where musical sound is included in at least one of the first sound or the second sound.

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.

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 into a memory for each of the keys. 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. In response to an operation of a key, a sound board vibration waveform corresponding to the operated key is read out from the memory, and the excitation device is driven in accordance with the read-out waveform signal so that the sound board is vibrated.
