| 骨导传声器在多种工作环境下表现出较强的抗噪性、稳定性和隐蔽性，具有广泛的应用前景。然而，骨导传声器的语音清晰度往往不如气导传声器，这导致其拾声质量较差，从而限制了其应用场景。改进骨导传声器的频率响应是提升其语音清晰度和拾声质量的有效方法之一。本文提出了一种骨导传声器频率响应高频拓宽的方法。该方法依据集总参数模型进行理论分析，改进了骨导传声器的器件结构，设计了其频率响应特性，拓宽了其有效频率范围。仿真与实验结果表明，经过高频拓宽的骨导传声器的频率响应与理论分析结果相吻合，高频拓宽方法能够实现频率响应调控并有效提升其拾声质量。 |
| 英文摘要: |
| Bone conduction microphones (BCM) exhibit strong noise resistance, stability, and concealability in various working environments, making them highly promising for a wide range of applications. However, the speech intelligibility of BCMs is often inferior to that of air conduction microphones, resulting in poorer sound pickup quality, which limits their application scenarios. Improving the frequency response of BCMs is one effective method to enhance their speech intelligibility. This paper proposes a method for broadening the high-frequency response of BCMs. The method is based on the theoretical analysis of the lumped-parameter model, which improves the device structure of the BCM, designs its frequency response characteristics, and broadens its effective frequency range. Simulation results and experimental results confirm that, through high-frequency broadening, the frequency response of the BCM matches the theoretical predictions, and the high-frequency broadening method can achieve the frequency response control and effectively improve the quality of sound pickup. |
