20090000464 | Percussion Detecting Apparatus and Electronic Percussion Instrument - A percussion detecting apparatus and an electronic percussion instrument, which are capable of not only providing excellent percussion feeling, but also visually indicating a percussion pattern of a beat applied to a percussion surface, so as to serve for percussion practice as well as to increase interest in the percussion practice. A head of the percussion detecting apparatus is formed of an air-permeable material and has a light transmitting property. The head includes a percussion surface. A drum shell supports the head. A head sensor detects a beat applied to the percussion surface of the head and outputs a beat signal indicative of the sensed beat. A light radiating part is disposed on an opposite side from the percussion surface of the head so as to perform visual indication corresponding to a percussion pattern of the beat applied to the percussion surface, at least through the percussion surface, based on the beat signal output from the head sensor. | 01-01-2009 |
20090020001 | DIGITAL CAPACITIVE MEMBRANE TRANSDUCER - A capacitive membrane is used as a digital sensor. Membranes act as binary devices, such as being in a collapsed or non-collapsed state.

20140165821 | Acostical optical pickup for use in a stringed musical instrument - An acoustic instrument is fitted with a flexible member that is fitted into the instrument and attached to the bridge of the instrument in such a fashion that the member vibrates freely in sync with the instrument. A compact optical pickup unit is attached to the flexible member in an arrangement comprised of cooperating optoelectronic devices which are mechanically isolated from the vibrations of the instrument and are positioned on the member. The member interferes with, and when stationary entirely obstructs, the path of a light beam generated by a light emitting device (LED) which is directed towards a light receiving device, the frequency and intensity of the vibrations of the member modulating the frequency and intensity of the light from the LED impinging on the receiving device. The result is an electronic output signal that corresponds to both the frequency of the note (or notes) played and to the tonal quality of the acoustic instrument on which the pickup is mounted. Circuitry associated with the receiving optoelectronic device is biased so that the output produces a signal which can be connected to any industry standard instrument amplifier or sound mixing board. | 06-19-2014 |
