Problems solved by technology

[0007] However, due to the influence of noise, etc., the output value may be output from the sensor that is not in contact with the lips. Therefore, as a reed for electronic musical instruments, it is desirable that the influence of such noise and the like does not affect the determination of the position of the lips.

[0111] Based on the above, the reed (reed 11 ) for an electronic musical instrument according to the first embodiment, particularly the touch sensor as the lip sensor 3 will be described in detail.

[0112] As the performance required for the contact sensor that detects the lip L, it is important that (a) the sensor value (also referred to as the output value) is constant even if the lip L moves on the reed 11 and the area in contact with the reed 11 is constant. value) remains constant; and, (b) the influence of noise is small in determining the center-of-gravity position XG of the lip L.

[0113] Furthermore, as described below, it was found that a substantially V-shaped shape is suitable as the outer shape of the sensor electrode of a touch sensor satisfying these conditions.

[0114] (When the sum of the respective output values ​​of multiple contact sensors is constant)

[0115] Consider a case where the lip L moves from the tip side to the root side while maintaining a ...

Abstract

To provide a reed for an electronic musical instrument and an electronic musical instrument in which the influence of noise or the like hardly affects the determination of the lip position. An electronic musical instrument (100) according to an embodiment of the present invention includes: a substrate having a front end side and a base end side; The sensor electrode has a central portion protruding toward the front end side of the substrate, and determines the player's lip position based on outputs from the plurality of sensors.

Description

technical field [0001] The present invention relates to a reed for an electronic musical instrument and an electronic musical instrument. Background technique [0002] In an acoustic wind instrument (for example, a woodwind instrument using a reed such as a saxophone or a clarinet), changes in the position and pressure of the lips and tongue in contact with the reed change the timbre of the musical sound to achieve a variety of performance performances. [0003] On the other hand, Patent Document 1 discloses an electronic musical instrument that electronically synthesizes and outputs musical sounds. [0004] In this electronic musical instrument, a plurality of pressure-sensitive lip sensors (pressure-sensitive sensors) are arranged on a reed to detect the positions of the lips and the tongue to control the musical sound. [0005] Patent Document 1: Japanese Patent Application Laid-Open No. 7-72853 [0006] As described above, in an electronic musical instrument including ...
