| 中文摘要: |
| 平衡衔铁受话器具有体积小、声压级高和失真小的特点，在助听器和高端耳机中已获得了广泛应用。文章简要介绍了平衡衔铁受话器的工作原理，详细讨论了国内外平衡衔铁受话器仿真分析方法的研究进展，涉及集总参数模型、有限元、边界元和传输矩阵等主要研究方法，重点关注它的非线性、声压级和失真等主要特性，并提出了进一步研究的重点和对未来发展的展望。 |
| 英文摘要: |
| The balanced armature receiver (BAR) has been widely used in hearing aids and high-end headphones because of its small size, high sensitivity and low distortion. After a brief introduction of the working principle of BAR, the advances of the simulation method of BAR are discussed in detail, including lumped parameter model (LPM), finite element method (FEM), boundary element method (BEM) and transmission matrices approaches, with focus on its nonlinearities, sound pressure level and distortion. The emphases of further research on the simulation method of BAR are suggested and the prospects of future development are put forward. |
