Abstract:
Using the analytical method,the relation of resonant length with displacement node and strain maxima point of the common horns is studied in this work. It can be found that the sum of displacement node and strain maxima is substantially equivalent to its resonant length. Such relation of the new type Bezier-profile horn is also calculated, and the numerical calculation agree well with the results obtained from the common horns. Rely on the relations, the process of design and calculation can be simplified.
KeyWords:
horn; Bezier-profile horn; resonant length; displacement node; strain maxima point
