摘要:
A sound source control information generating apparatus, an electronic percussion instrument, and a sound source control information generating method, adapted for preventing generation of an unintended sound caused by a rebound of an object placed on one struck head, are provided. According to the present invention, if a first output value with respect to one struck head is obtained, the one struck head serves as a target struck head, and information is generated for controlling a sound source means such that a sound generation process performed by the sound source means differs according to whether the first output value obtained with respect to the target struck head or a value corresponding to the first output value is greater than a predetermined threshold value.

An electronic cymbal includes a disk-shaped main body portion and a striking sensor. A covering member is provided to cover an outer circumferential edge portion of the main body portion and includes an upper covering portion covering an upper surface side of the main body portion, an extending portion extending further toward an outer circumferential side than the outer circumferential edge portion of the main body portion, a lower covering portion covering a lower surface side of the main body portion. The striking sensor at least includes an edge sensor between the lower surface of the main body portion and the lower covering portion, and by pressing down the extending portion, the lower covering portion is elastically deformed in a direction toward the main body portion to sandwich the edge sensor with the lower covering portion and the main body portion and press the edge sensor.

Mit der Erfindung soll ein elektroakustisches Tonabnehmersystem dahingehend verbessert werden, dass es ein höheres Mass an Möglichkeiten der Einstellung unterschiedlicher Klangarten bzw. Sounds eines mit diesem Tonabnehmersystem bestückten Saiteninstrumentes bietet. Damit insbesondere für ein bereits mit zwei oder mehr Tonabnehmerelementen ausgestaffetes Saiteninstrument eine grössere Klangvielfalt des Instrumentes erreicht werden kann, wird vorgeschlagen, dass dieses eine Relaisverschaltung (21) erhält, über die die einzelnen Tonabnehmerelemente (15.1,15.2,16.1,16.2) wahlweise dem Signalausgang (22) zuschaltbar angeschlossen sind. Mit der Erfindung wird ferner ein mit einem solchen Tonabnehmersystem ausgestattetes Saiteninstrument angegeben.

A transducer (120) for a stringed musical instrument utilizes a coaxial structure. An electromechanical film tape is disposed about an inner, electrically conductive core (210). An outer conductor (230) is formed about the electromechanical film tape. The electromechanical film tape may be provided as a piezoelectric polymer film (200) or an electret film having a permanent electric charge, and is formed about the inner core by wrapping or braiding. Prior to being disposed about the inner core, the film tape may be polarized through the application of a direct current through the film to substantially align the electrical domains in the film. The transducer (120) is configured for placement underneath the saddle in a bridge of a string musical instrument.

Provided is a transducer that can be attached to a desired position and removed therefrom and that does not damage musical instruments. A first magnet member (32) and a second magnet member (34) are mutually attracted toward one another by magnetic force across the top board of a ukulele. Thus, a receiver unit (30) including a piezoelectric element (36), which is supported by the first magnet member (32), can be positioned at a desired position. Because the receiver unit (30) is kept in position only by the mutually attracting magnetic forces, the receiver unit can be moved to any desired position even after once being positioned on the top surface of the ukulele.
摘要:
As part of a system, a device is provided as part of a system, the device being for capturing vibrations produced by an object such as a musical instrument. The device has a first sensor placed in contact with a surface of the drum, such as a rim of the drum, and a second sensor placed at a fixed location relative to the drum, but not touching the drum. A method may be provided for interpreting the output of the sensors within the system, the method comprising identifying the onset of an audio event in audio data, selecting a window in the data for analysis, applying transforms to generate a representation of the audio event, and comparing that representation to expected representations in a model.

Provided is a device (20) for vibrating a string instrument (1) to allow the string instrument to be used as a loudspeaker. To press a base member (22) fitted with a vibration generator (50) against a bridge (13) of the string instrument (1) via a load point member (24) of a vibration transmission member (26), the base member (22) is provided with a fulcrum member (30) engaging an upper side of the strings (9) of the string instrument (1) and an anchor member (38) engaging a lower side of the strings (9). In order to urge the vibration transmission member (26) against the bridge (13), a cam mechanism (40) presses the anchor member (38) against the lower side of the strings (9).
摘要:
An electro-mechanical musical instrument capable of generating a whole or partial instrument resonant frequency, said instrument comprising a body (1) having a first end (2) and a second end (3), a soundboard (4) positioned between said first and second ends adapted to generate a live frequency response and a contact microphone or sensor (5) adapted to receive said resonant frequency wherein said body includes a rigid member (6) positioned between said first and second ends of said body, said rigid member being adapted to apply tension or compression between said first and second ends of said body and simultaneously contact said soundboard between said first and second body ends such that said application of tension or compression adjusts or modifies said resonant frequency of said instrument.
