| 中文摘要: |
| 耳机的频响是由单元和腔体结构共同决定的。现有的耳机腔体结构仿真多采用集总参数模型，这类模型在高频段存在缺陷。本文在入耳式耳机的腔体结构仿真中引入基于传输线理论的声学模型，与实际测量结果相比表明该模型可提高耳机高频频响仿真的准确性。在此基础上，优化算法提出改善耳机中高频频响的出声管设计方法。 |
| 英文摘要: |
| The cavity structure of insert earphones will affect the frequency response. The existing earphone structure simulation model is mainly based on the lumped-parameter model. To improve the simulation precision of the lumped-parameter model in high frequency range, the simulation of the cavity structure based on the transmission line model is proposed. The results show that the simulation based on the transmission line model is close to the measured results. Based on the model, the optimization algorithm is proposed to improve the design of the high frequency response of the headphone. |
