The counter electrode is coupled to the transducer substrate. The diaphragm is oriented substantially parallel to the counter electrode and is spaced apart from the counter electrode to form a gap. A back volume of the MEMS transducer is an enclosed volume positioned between the counter electrode and the diaphragm. A height of the gap between the counter electrode and the diaphragm is less than two times the thermal boundary layer thickness within the back volume at an upper limit of the audio frequency band of the MEMS transducer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sub-miniature microphone","description":"A MEMS transducer includes a transducer substrate, a counter electrode, and a diaphragm.
