摘要： A modulated electromagnetic musical instrument and sound reproduction system includes an acoustic carrier signal source, a modulation signal source, a linkage element, and an acoustic output. The acoustic carrier signal source is produced electromagnetically or mechanically via human instrument playing. An electromagnetic modulation source mixes with the acoustic carrier signal within a linkage element to produce a nonlinear behavior. This nonlinear behavior's coupled interaction with a physical medium or acoustic body produces sideband frequency components to form unique musical sound outputs and audio effects.

摘要： A stringed instrument pickup with multiple selectable coils can be utilized in a system to provide a diverse range of sound characteristics from at least one moving string under tension. A first wire can be connected to a first terminal of a first bobbin body prior to the first wire being wound around the first bobbin body a first number of times and then connecting the first wire to a second terminal of the first bobbin body. A second wire may be connected to the second terminal of the first bobbin body before winding the second wire around the first bobbin body a second number of times and then connecting the second wire to a third terminal of the first bobbin body. The first bobbin body is subsequently mounted onto a stringed instrument.

摘要： Embodiment apparatus and associated methods relate to adapting an actuator to adjust the tension of a musical instrument string, configuring a sensor to detect vibration propagated through the musical instrument body, configuring a noise removal filter to remove an undesired signal from vibration propagated through the musical instrument body, and automatically tuning the musical instrument based on adjusting the musical instrument string tension by the actuator while removing the undesired signal, until the fundamental frequency propagated through the instrument body by the vibration of the musical instrument string is within a predetermined tolerance of a reference frequency. In an illustrative example, the undesired signal may be actuator vibration. In some embodiments, actuator vibration spectral content may vary as a function of actuator torque, and, the noise removal filter may be adapted in real time. Various examples may advantageously provide faster and more accurate stringed musical instrument tuning.

摘要： A sound capture device is affixed to an acoustic instrument to capture the natural sound output of the instrument. The captured sound signal is routed to an electronic sound augmentation system that is configured to augment the captured sound with spatial sound effects such as reverb, echo, delay, etc. The processed and augmented sound is then reproduced via a vibrating driver that has been affixed to the body of the acoustic instrument. This creates a situation where the body of the musical instrument, responding to a series of vibrations produced by the vibrating driver, acts as a speaker component, reproducing a rich augmented sound output that comprises the sum of the sound produced by the original sound production capabilities of the acoustical instrument plus the added augmented or enhanced sound effects.

摘要： An electric-acoustic stringed instrument has a removable, adjustable and acoustic artwork top with a decorative bridge and tailpiece; a mounting system for electric string vibration pickups that allows five degrees of freedom in placement and orientation of each pickup anyplace between the neck and bridge; a pickup switching system that provides K*(K−1)/2 series-connected and K*(K−1)/2 parallel-connected humbucking circuits for K matched single-coil pickups; and an on-board preamplifier and distortion circuit, running for over 100 hours on two AA cells, that provides control over second-and third-harmonic distortion. The switched pickups, and up to M=12 switched tone capacitors provide up to M*K*(K−1) tonal options, plus a linear combination of linear, near second-harmonic and near-third harmonic signals, preamp settings, and possible additional vibration sensors in or on the acoustic top.

摘要： 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.

摘要： A speed detecting apparatus for a keyboard musical instrument is provided for accurately detecting the speed of bivotal movements of a hammer and a key even if a shutter implies errors in its attachment, without affected by such errors. The speed detecting apparatus for a keyboard musical instrument comprises a pivotable key, a hammer pivotably supported by a fulcrum and configured to pivotally move in association with a pivotal movement of the key, a shutter integrally attached to the hammer, a plurality of detectors, each having a light emitter and a light receiver for receiving light emitted from the light emitter, arranged on one and the other sides of the pivotal movement path of the shutter, and a CPU for detecting a pivot speed of the hammer in response to timings at which the shutter opens and closes the light paths of the light of the plurality of detectors when the hammer pivotally moves. The plurality of detectors have detection points on respective light paths of the light from the light emitters, and are arranged such that the detection points are positioned on an arc centered at the fulcrum of the hammer.

摘要： In an automatic player piano, hammer sensors monitor associated hammers so as to report current positions on the hammer trajectories, and a data processor analyzes the hammer motion for producing pieces of music data representative of the performance on the acoustic piano; the aged deterioration is influential in the relative position between the hammers and the hammer sensors so that the data processor rectifies the relative position, the data processor determines the turning point at which the hammer changes the direction of motion, and compares the current value indicating the turning point with the previous value; if the difference is found, the data processor adds a value of deflection of strings to the current value so as to determine and memorizes the true value of the turning point; the data processor analyzes the hammer motion on the basis of the true value so that the music data are reliable.
