Description

Technical Field

[0001] This utility model relates to the field of accordion technology, and in particular to an accordion airflow valve. Background Technology

[0002] During accordion playing, sound is produced by pulling the bellows to create airflow that blows the reeds and causes them to vibrate. When pulling the bellows, there are usually conventional techniques such as forward fan-shaped, inverted fan-shaped, and horizontal pulling. The performer needs to control the duration of the key presses according to the rhythm of the movement and ensure that the performance of the current rhythm ends when the bellows are switched forward.

[0003] However, in existing equipment, when the bellows is pulled, the airflow enters the bellows through the air inlet and the one-way valve inside the bellows. However, the size of the air inlet is fixed and the airflow cannot be adjusted. If the air inlet is small, it is more difficult for the performer to pull the bellows. Therefore, an accordion airflow valve is proposed. Utility Model Content
