  • Patent number: 9905212
    Abstract: An arched top bridge upper section including a wood top section slotted to accept a string saddle that may be plastic, bone or similar material. The wood section is laminated or affixed to a lower metal section. A slot completely through the wood section exposes a top flat surface of the metal section. A piezo pickup element installed in the slot below a solid or segmented string saddle element is pressed uniformly against the metal section by string pressure on the string saddle to ensure even response on all strings. Transfer of string energy is more efficient than standard all-wood construction, resulting in greater sustain of plucked notes and a broader frequency response. An arch top guitar utilizing this bridge construction has more similar tonal and sustain characteristics to a typical flattop acoustic guitar while consistent contact with the piezo element results in even string-to-string output and response.

A gaming apparatus including a gaming device and a vibrating headset communicably coupled to the gaming device for generating vibrations of variable operational characteristics in response to receiving a vibration input signal from the gaming device is also provided. Finally, a method of creating vibrations defined by at least one variable operational characteristic in an earpiece of a vibrating headset is provided.

  • Patent number: 9082378
    Abstract: A supporting structure for an electronic pad of a percussion instrument includes a pad member, a pair of a first engaging part and a second engaging part, and a connecting part which connects a first object (e.g. a leg fixed to a stand) and a second object (e.g. the second engaging part) in a rotatable manner about the rotation center. The connecting part includes a rotation-regulating unit which regulates the rotational displacement of the second object within the regulation range irrespective of a rotational torque less than a predetermined value which is applied to the second object disposed at the initial position relative to the first object. Due to a rotational torque above the predetermined value, the rotation-regulating unit shifts the regulation range so as to shift the initial position, and therefore the second object will be restored to the new initial position.

  • Patent number: 9047852
    Abstract: The Pole Position Sliding Pickup System changes the way tonal variety is arrived at by electric guitar players. Rather than installing multiple pickups in different positions in order to achieve a limited variety in tone, the Pole Position Sliding Pickup System uses a single pickup which can be moved quickly and easily to any position between the base of the neck and the bridge in order to achieve a much greater variety in tone, and create wah wah-like sound effects by manipulating the pickup at different speeds and distances. Not only are the variety of possible tones increased, but so is the ease with which they can be attained, because the method of sliding the pickup into place is easier than conventional methods of choosing stationary pickups.

  • Patent number: 9035160
    Abstract: A percussion controller comprises an instrumented striker including devices for obtaining inertial measurements and a wireless transmitter, a sensor-enabled striking surface that receives an impact from the instrumented striker, and a data processing system that receives the inertial measurements and predicts at least one of the force or location of impact of the instrumented striker on the sensor-enabled striking surface before impact actually occurs.

  • Patent number: 9024171
    Abstract: A sensor assembly for a stringed musical instrument having a plurality of movable strings includes a primary winding extending outward to form a mounting member and adapted to be disposed on the stringed musical instrument. The sensor assembly includes at least one magnet disposed adjacent the primary winding to generate a magnetic field. The primary winding creates a primary current from a disruption in the magnetic field by the movable strings and the primary current creates a primary electromagnetic flux. The sensor assembly further includes at least one secondary being coupled to the primary winding. The at least one secondary winding transforms the primary electromagnetic flux into a secondary current adapted to pass out the stringed musical instrument.

  • Patent number: 9024172
    Abstract: 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.

  • Publication number: 20150114210
    Abstract: An inflatable electronic drum set includes an inflatable bladder, which when inflated, forms a three-dimensional outer configuration of a combination of a drum set and including multiple structural sections of drums and cymbals. The interior is filled up with air and each drum surface or cymbal surface is provided with a pressure detection film, so that through settings made with a control module, when a drummer hits, a corresponding drum sound or cymbal sound is generated. The inflated music instruments are set at positions corresponding to those of a traditional drum set. Due to high resiliency and flexibility, percussion can be made with perfect hand perception and no concern about collision and tumbling may be caused. Another advantage is that the sound volume can be adjusted. In addition, after air is completely discharged, the drum set can be stowed in a very limited space.

    Abstract: A sensor obtains an angular rate of a stick member. A sound source map includes plural areas disposed in a virtual space. CPU presumes a direction of a turning axis of the stick member based on the angular rate obtained by the sensor, while a user is operating the stick member, calculates an angular rate of a top of the stick member based on the angular rate obtained by the sensor with the angular rate in the longitudinal direction of the stick member removed, calculates a position of the holding member in the virtual space after a predetermined time, based on the recent direction of the turning axis of the stick member and recent angular rate of the top of the stick member, and sends a sound generating unit a note-on event of a musical tone assigned to an area corresponding to the calculated position among the plural areas.

  • Patent number: 9006554
    Abstract: A human interface device may include at least one analog control pressure surface that may operate in conjunction with at least one optical tube assembly (OTA) to allow precision human control of signal modulation, such as an audio signal being generated by a musical instrument. Each OTA may be incorporated within a body and may include a tube and an emitter-sensor pair wherein when pressure is applied to at least one of the pressure surfaces, the amount of light transferred within a sensor-emitter pair of an OTA is altered to selectively effect the signal modulation. Any type of control range may be expressed that depends on dynamic range and “touch” control. Accordingly, the human interface device may allow more “feeling” or expressiveness through application of pressure rather than positioning.
