Microphones work as a transducer that converts acoustic energy into electrical energy that can be amplified, recorded or transmitted.  Microphones have different directionality properties that define the microphone’s sensitivity to sound from various directions and a pickup pattern that determines how the microphone picks up sound from various directions. These properties are used to divide microphones into three categories: noise canceling, omni-directional and uni-directional.  

PUI Audio microphones are offered in noise canceling, uni-directional and omni-directional options and have a small profile with high sensitivity. Our lead wire microphones are used for various medical, automotive, industrial, and consumer product applications. We provide lead wire microphones in a large selection of shapes and sizes, including:

• Diameter sizes from 4mm to 10mm
• Heights from 1.2mm to 7mm
• Lead wire and solder pad mounting options
• Operating temperature range of -20C ~ +70C
• Storage temperature range of -40C ~ +85C
• Superior signal-to-noise ratio  

Selecting the right Microphone for Your Application

To be effective and produce the best sound, a microphone needs to clearly and accurately capture sound with minimal background noise. Our lead wire microphones are available in the following options:

  • Noise Canceling Microphones: pick up sound from two opposite directions, front and back, and are used for applications where ambient sounds need to be filtered from the desired sound.
  • Omni-Directional Microphones: picks up sound equally from all direction and has a low grain to feedback ratio, low sensitivity to wind and handling, low distortion, and no proximity effect.
  • Uni-Directional Microphones: are sensitive to sounds coming from just one direction, is less susceptible to feedback and pick up less directional noise.
