Title:
REED FOR ELECTRONIC WIND INSTRUMENT AND ELECTRONIC WIND INSTRUMENT
Document Type and Number:
Japanese Patent JP2020160147
Kind Code:
A
Abstract:
To provide a reed for an electronic wind instrument capable of suppressing an influence of moisture to excellently detect a contact position of a human body, and an electronic wind instrument to which the reed is applied.SOLUTION: A reed body 22 applied to a mouthpiece 10 of an electronic wind instrument 100 has a stack structure in which a sensor electrode 32 of a first layer L1, a wiring group 44 of a second layer L2, a shield electrode 52 of a third layer L3, and a ground electrode 62 of a fourth layer L4 are stacked such that respective plane patterns thereof overlap in plane view. The sensor electrode 32 is a capacitance type sensor for detecting a contact position of a lip LP with the mouthpiece 10 bitten, and the shield electrode 52 is applied with a shield signal in synchronism with waveform change of a touch detection signal output from the sensor electrode 32.SELECTED DRAWING: Figure 8
