  • Patent number: 11610570
    Abstract: An electronic percussion instrument and sound production control method thereof are provided. In an electronic cymbal, the output of a musical sound is controlled in accordance with the results of detection from a strike sensor when the strike sensor detects a strike on a striking surface. While the musical sound is output, if a user touches the striking surface, an electrostatic capacitance sensor outputs an output value in accordance with the contact condition so that the musical sound is attenuated in accordance with the output value while being output. Therefore, the user can attenuate the musical sound being output in accordance with the contact conditions on the striking surface, thereby silencing the musical sound by way of the action similar to that of the acoustic cymbal choke that is the action of touching the striking surface.

  • Publication number: 20230029113
    Abstract: Provided is a keyboard device for which the number of parts can be reduced. The present invention is provided with: hammers rotatably linked to a chassis; keys rotatably linked to the hammer thereof; guiding pins provided to the keys and extending in the widthwise direction of the keys; and a guiding groove provided to the chassis side and into which the guiding pins are inserted. The downward displacement of the front-end sides of the keys is guided by the rotation of the hammers with respect to the chassis, and the downward displacement of rear-end parts of the keys is guided by the sliding of the guiding pins with respect to the guiding groove. This eliminates the need for links to guide the displacement of the rear-end parts of the keys, thus allowing the number of parts to be reduced.

  • Publication number: 20230020640
    Abstract: A pedal device receives a connection signal transmitted from headphone to establish first communication that is communication with the headphone. Then, in a case where the first communication has been established, the pedal device transmits the connection signal including information indicating that communication with the headphone has been established. By receiving the connection signal from the pedal device, a portable terminal establishes second communication that is communication with the pedal device. In a case where the received connection signal includes information that the communication with the headphone has been established, the portable terminal may determine that communication establishment between the pedal device and the headphone has been completed.

  • Publication number: 20230016374
    Abstract: Provided is a keyboard device that can suppress a reduction in the operability of a key. A rear guiding member comprises a pair of guiding surfaces that, in a side view of a key, face forward and rearward and are formed along an arc that is convex toward the front. The key comprises a pair of sliding surfaces that slide against the pair of guiding surfaces. Due to this sliding of the guiding surfaces and the sliding surfaces, rotation of the key can be guided while displacement of the key in the front-rear direction is regulated. Consequently, because forward and rearward displacement of the key during key pressing can be suppressed, a reduction in operability (feeling of touch) during pressing of the key can be suppressed.
