Performance assist apparatus of wind instrument

The invention relates to a wind device for auxiliary device. The device comprises: The driving device, which is connected with the wind instrument, a vibration with one part of wind device of assisting to the performance of wind meter; A microphone, a receiving of wind device is arranged on the vibration of sound, and represents to said sound the signal of the; Breathes a pressure sensor, is injected of wind meter breath pressure in the performance process for detecting, a breath pressure signals for generating and a detecting is provided with a breath voltage of; correspondingThe controller, for generating a control signal, wherein the control signal with the signal a reciprocating value and breath pressure signals of the product is corresponding; The variable-diameter the amplifier, for using response of the variable of the control signal of parallel to the vibration signal, and collected by the output is a signal to the guide part, so as to the vibration to the wind device with one part.
