摘要：为弥补现有声波传感器易受电磁干扰和环境影响的缺陷,设计制作了一种锥形微纳光纤振动传感器。通过多次对照重复实验,分别测量了相同声强条件下20~20000 Hz声波频率范围内的声波响应,以及800 Hz固定频率下不同声强对应的振幅变化,随后,利用软件对实验数据进行处理与分析。实验结果表明,该传感器检测的声波频率与实际声波频率、声波振幅与实际声强均高度吻合,示波器显示的检测波形具有良好的周期性。
This study aims to design and fabricate a tapered micro-nano optical fiber vibration sensor to address the limitations of existing acoustic sensors in the market,such as susceptibility to electromagnetic interference and environmental factors.Repeated controlled experiments were conducted to measure the sensor’s response to acoustic frequencies ranging from 20 to 20000 Hz under identical sound intensity,as well as the amplitude of acoustic waves at 800 Hz under varying sound intensities.Experimental data were processed and analyzed using specialized software.Experimental results indicate that the sound wave frequency detected by the sensor is highly consistent with the actual frequency,and the sound wave amplitude detected is highly consistent with the actual sound intensity.The detected waveforms displayed on the oscilloscope exhibit excellent periodicity and stability.
