Heart Sound Sensor

This Heart Sound sensor integrated micro-sound components which is made from new polymer materials, can output low-impedance audio signal. Using modular design, PCB plug-way closed. It can be widely used in various types of acquisition equipment, such as heart sound signal acquisition, fetal-audio signal acquisition, as well as other surface-tone signal acquisition.


  • Output analog voltage signal
  • High-fidelity, low-impedance audio signal
  • High integration, reliability
  • Overload range 100 times
  • Anti-jamming design

Application Ideas

  • Heart sound signal acquisition
  • Fetal-audio signal acquisition
  • other surface-tone signal acquisition
