Subminiature Electret Microphones
Hundreds of legacy design possibilities can be applied to your product challenge with our electret microphones. Ideal for products that require premium audio and very small form factors, solutions include noise canceling, omni-directional and unidirectional performance. Other variables include size, shape, amplification, sensitivity, low noise, and resistance to vibration and mechanical shock. For more modern designs, we recommend our offering of low power hearing health MEMS mics.
