- •
An extended neck or a spiral neck takes place of a traditional straight neck in a HR.
- •
Modified 1D analytical approach and equivalent approach are revealed.
- •
The acoustic performance of a HR with these two types of necks is analyzed.
- •
The prediction results are compared with Finite Element Method results.
