US 7,985,916 B2 · Electronic wind instrument and zero point compensation method therefor

Abstract

Electronic wind instrument includes: a breath flow detector detecting a flow of breath blown by a user; a tone generator forming a tone signal; a control section controlling the tone generator on the basis of an output signal of the breath flow detector; and a zero point compensation section that, when a predetermined condition has been satisfied, compensates a zero point of the output signal of the detector on the basis of the output signal generated by the detector at the time point the predetermined condition has been satisfied. The predetermined condition is satisfied when it is detected that a zero point compensation switch operable by the user has been turned on, that no performance is being executed by the user, that a value indicated by the output signal of the detector has decreased below a predetermined threshold value, or that the wind instrument has been turned on.

Dependent claims

An electronic wind instrument comprising:

a pipe section;
a lip plate provided on the pipe section, wherein a blow hole is provided in the lip plate to provide an open space instrument type;
a breath flow detector that detects a flow of breath blown by a user through the blow hole of the lip plate;
a tone generator that forms a tone signal;
a control section that controls said tone generator on the basis of an output signal of said breath flow detector;
and
a zero point compensation section that, when a predetermined condition has been satisfied, compensates a zero point of the output signal of said breath flow detector on the basis of the output signal generated by said breath flow detector at a time point the predetermined condition has been satisfied.

A non-transitory computer-readable storage medium containing a group of instructions for causing a computer to perform a zero point compensation method of providing zero point compensation for an electronic wind instrument including a pipe section and a lip plate provided on the pipe section, wherein a blow hole is provided in the lip plate to provide an open space instrument type, the method comprising:

detecting a flow of breath blown by a user through the blow hole provided on the lip plate with a breath flow detector;
forming a tone signal with a tone signal generator;
controlling the tone generator on the basis of an output signal of the breath flow detector with a control section;
compensating a zero point of the output signal of the breath flow detector on the basis of the output signal generated by the breath flow detector at a time point when a predetermined condition has been satisfied by performing a zero point compensation process with the control section.
