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.

A percussion instrument may include a plurality of coupling device for operatively connecting a first hoop member, which may be configured to hold down a head arranged across a first end of a shell, with a rear surface hoop, which may be arranged on a second end of the shell. A sensor adjacent the head configured to detect vibration of the head may be operatively connected to the rear surface hoop.

A drumhead comprising a mesh membrane having a bottom surface and a damper contacting at least a portion of the bottom surface for improved rebound. Also, a practice drumhead assembly including a mesh membrane held in substantially fixed relation to an acoustic membrane. The assembly preferably includes an annular tensioning ring for tensioning the mesh membrane, and an engagement member for substantially fixing the mesh membrane relative to the acoustic membrane. Additionally, a tensioning ring for a drumhead comprising a cylindrical rod with a turnbuckle that is rotated to increase the diameter of the tensioning ring.

A pad member (12) of an electric percussion instrument is supported through a cushion member (16) by a case member (11) for isolating the pad member from noise produced in the case member upon strikes of the pad member, and a vibration sensor (15) is connected with the pad member (12) by means of a holder (13/14) of vibration transmitting substance so as to propagate the vibrations of the pad member to the vibration sensor without any influence of the noise.
摘要:
The invention provides an electronic percussion instrument capable of improving detection accuracy for a strike. The electronic percussion instrument of the invention includes a plate-like pad that has a front surface to be struck, a sheet-like pressure sensor that is provided on a back surface of an outer circumferential end portion of the pad and that detects a pressure change, and a weight portion that contacts a front surface of the pressure sensor, wherein, due to striking on the front surface of the pad, an inertial force from the front surface of the pressure sensor toward a back surface of the pad acts on the weight portion, and the weight portion presses the pressure sensor.
