A laser trigger for a bass drum includes an enclosure attached to a drum rim which contains at least one reader of strokes performed with a foot pedal beater. The stroke reader is directed towards the beater, and has a laser beam emitter and the photoelectric element, whereas the retroreflective coating is applied on the pedal beater to reflect the laser beam in the direction of the photoelectric element at the moment of stroke. The enclosure/housing cavity includes a stroke recognition circuit based on parameters of the electric signal from the photoelectric element connected with the processing circuit that includes an audio frequency electric signal generator, which is connected with the output connector to connect the cable for outputting these signals for further processing and amplification.

A music based video game provides a user directed sound generation feature. In some embodiments, the user is provided a video game controller simulating a musical instrument, which the user may operate similarly to its real musical instrument counterpart. A free play feature is provided for users to operate the video game controller, where a processor of a video game console receives input signals from the video game controller and outputs audio samples based on the received input signals. During the free play feature, multiple suggestions as to how to operate the video game controller are simultaneously provided to give users some guidance as to what to play using the video game controller.

There is provided an electronic percussion instrument. The electronic percussion instrument includes a struck surface and a plurality of strike sensors configured to detect a strike on the struck surface. The plurality of strike sensors include at least one central sensor that is disposed on a back side of the struck surface and disposed at a center side of the struck surface and a plurality of peripheral sensors that are disposed on a peripheral side of the struck surface. The central sensor and the peripheral sensors each have the same structure. The peripheral sensors are configured to transmit a strike signal in a shorter time than the central sensor when the struck surface is struck.

Disclosed are a device and a method for testing impedance characteristic and expansion performance of a sound absorption material. The device includes a first cavity and a second cavity which are both sealed. The first cavity is communicated with the second cavity through a slit channel. The second cavity is used for placing a sound absorption material therein. The device further includes a sound excitation source whose sounding face is located in the first cavity and used to provide a testing sound pressure. The device further includes two sound pickup sensors whose sound pickup surfaces are respectively arranged in the first cavity and the second cavity and respectively used to detect sound pressure in the first cavity and the second cavity. The device further includes a material for enclosing the first cavity and the second cavity is a hard sound insulation material.

Devices, systems, and methods that make music in response to be contacted by a stream of liquid are disclosed. A music making device may include a sensor to detect when a stream of liquid is substantially in contact with the sensor. The sensor may produce an indicator signal at or around the time the liquid substantially contacts the sensor. A circuit may generate an electrical pulse in response to detecting the indicator signal. The electrical pulse may be coupled to a speaker which converts the electrical pulse into sound.

Electronic musical instruments as disclosed, include sensors to digitize and alter the sound using FSR sensors in the mouthpieces and other elements of the instrument to mimic the variations available in analog instruments.

There is provided an electronic percussion instrument including a struck surface and strike sensors. The strike sensors include a central sensor; a plurality of peripheral sensors; a first position calculation device configured to, when an initial half wave of a strike waveform of the central sensor is detected within a first predetermined time after the central sensor detects a strike, calculate a first strike position from the central sensor based on the initial half wave; a second position calculation device configured to calculate a second strike position based on a difference in strike detection by the plurality of peripheral sensors; and a sound production instruction device configured to instruct production of a striking sound based on the first and second strike positions respectively calculated by the first and second position calculation devices.

The inventive device relates to musical instruments. Use of this invention in a stringed instrument ensures a simpler apparatus allowing for sounding a string of the stringed instrument in the same way as a musician does. The apparatus for sounding a string of stringed instrument comprises: a first servo motor designed for securing a mediator to an output shaft thereof and for rotating the mediator in opposing directions for ensuring an interaction of the mediator with the string; a guide disposed substantially orthogonally to the string plane of the stringed instrument and designed for moving, along one side thereof, the first servo motor from or to the string; a second servo motor mounted at the reverse side of the guide; a transmission mechanism which first end being coupled with an output shaft of the second servo motor and which second end being connected to the first servo motor.

Waking-up a violin or other instrument by determining naturally resonating features of a particular instrument by applying tones and analyzing the instrument's responses, and then applying vibrations (e.g., continuously and/or in patterns, such as alternating on/off, staccato, etc.) corresponding to the most responsive (resonant) portions of the instrument's responses (e.g., peaks of the analyzed instrument's response) fully breaking in the various parts of the instrument. The applied vibrations are continued until the instrument's amplitude response plateaus.
