An electronic musical instrument includes a database including timbre data corresponding to a plurality of musical instruments an acoustic data input unit configured to display an acoustic data input position corresponding to a selected one of the musical instruments, detect whether the acoustic data input position is touched, and receive information on the touched acoustic data input position a mouthpiece detachably provided and having a shape corresponding to a shape of a mouthpiece of the selected musical instrument a wind sensor unit configured to measure an amount of air to generate loudness data a control unit configured to receive timbre data corresponding to the information on the touched acoustic data input position, receive the loudness data from the wind sensor unit, and synthesize the timbre data and the loudness data to output an acoustic sound signal of the selected musical instrument and a power supply unit configured to supply power.

A wearable sensor system is disclosed that provides a measurable magnetic field that changes horizontally within the range of motion of human limbs. The wearable sensor system includes a magnetic sensing device, and one or more magnet devices that provide the measurable magnetic field with a strength exceeding the Earth's magnetic field. To this end, the magnetic sensing system provides a personal magnetic field about a user, with that magnetic field traveling with the user and overpowering adjacent interfering fields. The wearable sensor system may include a sensor arrangement that measures a strength of the personal magnetic field and field direction to perform horizontal localization, and may send a representation of a same to a remote computing device to cause an action to occur. Some such actions include output of pre-recorded or synthesized musical notes, for example.

A musical instrument with novel configurations and performance techniques that can play notes and scale tones is disclosed. The musical instrument implements design and ergonomic changes to a Theremin's traditional configuration and use. The musical instrument includes an additional sound generation device such as an actuator that is operated to provide rhythm and tonal results. The musical instrument includes a pitch antenna that is configured in a horizontal position, which creates a different plane of reference with respect to performance motions employed for modifying the pitch. The musical instrument allows for a user to play notes and scale tones in a standing, seated, or ambulatory position. Improved playing interfaces, accessory items, and other characteristics for enhancing the playing of the musical instrument are provided.

A vibrato tailpiece system for a stringed instrument includes a tailpiece, a vibrato bar operable with the tailpiece and having an end portion rotatable about an axis of rotation, and a magnet attached to the end portion of the vibrato bar. A sensor chip is spaced from the magnet by a gap sufficiently small to enable the sensor chip to detect a change in the magnetic field due to a rotation of the vibrato bar. The sensor chip outputs a control signal based on the change in the magnetic field. A sensor circuit uses the control signal from the sensor chip to adjust or modify the pickup output signal based on the position of the vibrato bar and deliver an adjusted output signal to an output connector of the stringed instrument.

An instrument playing apparatus has: a movable member configured to be displaced responsive to a playing operation of a user; a detection part formed from a magnetic or conductive body and disposed on the movable member; and a filter that includes a coil. The filter has a frequency response that changes depending on a distance between the detection part and the coil, and generates a detection signal from a reference signal.

A first detection signal is generated based on a distance between a first detectable coil disposed on a first key and a first drive coil. A second detection signal is generated based on a distance between a second detectable coil disposed on a second key and a second drive coil. The first drive coil includes first and second drivers through which current flows in a first direction and in a second direction opposite to the first direction, respectively. The second drive coil includes third and fourth drivers through which current flows in the first direction. The first detectable coil includes first and second portions in which induction currents in opposite directions are generated by electromagnetic induction of the first drive coil. The second detectable coil includes third and fourth portions in which induction currents in the same direction are generated by electromagnetic induction of the second drive coil.

Since the curvature of a plane part 82b is smaller than that of a curved surface part 82a, it is possible for the distance between a coil 100 and the detected part 82 (plane part 82b) to be short in the aftertouch performance region than the case where the detected part 82 is one arc shape centered on a rotation shaft 90. Accordingly, the dynamic range can expand (with a significantly decrease in the sensor output value in the aftertouch performance region) without enlarging the displacement member 8 (coil 100). Accordingly, aftertouch can be accurately detected while the displacement member 8 can be miniaturized.

Since a white key 2a and a holder 9 to which the displacement member 8 is pivotally supported are assembled to the same chassis 4, the relative positional accuracy between the white key 2a and the displacement member 8 can be improved. As a result, the guide pin 73 of the linkage member 7 and the groove 80 of the displacement member 8 can be accurately engaged at the position as designed. Therefore, the initial position (angle) of the displacement member 8 before key-pressing and the displacement amount (rotation amount) of the displacement member 8 accompanying key-pressing are more likely to follow the design value. Consequently, the key-pressing information of the white key 2a can be detected with high accuracy.

An electronic hi-hat 1 has a rod movable up and down with an operation of a player. A top cymbal 2 has a striking surface that can be struck by the player. A bottom cymbal 3 comes into contact with or separates from the top cymbal 2. An optical sensor 7 detects separation dimension between the top cymbal 2 and the bottom cymbal 3. The optical sensor 7 detects separation dimensions of a plurality of areas that are displaced with inclinations of the top cymbal 2 and the bottom cymbal 3 with respect to the rod r. The plurality of areas where the separation dimensions are detected are located on a common circumference of the top cymbal 2 and the bottom cymbal 3 around the rod r as a center.
