The voice command, which is used in smart phones, wearable electronics, and many other devices require always-on microphone. Electrodynamic microphones being active, do not require a power supply, but due to the design dimensions, they are unsuitable for use in modern mobile devices.
In addition, the microphone Knowles SPH0641LM4H-1 20% less counterparts - it measures just 3.50 x 2.65 x 0.98 millimeter - and has the highest signal to noise ratio of low-power MEMS-microphones equal 64.3 dB. Microphone Knowles Electronics manufacturers have already estimated, the device has been in production since the first quarter of 2014, also under supply solutions to customers.
Low power microphone is provided by the emergence of a new state of constant listening mode (besides the standard states and sleep), with a simple name super low-power. The microphone is able to distinguish the voice command even in the presence of a strong background noise, and operates in the range of from 45 to 20 000 Hz. Related Products :
