Miniature microphone assembly with solder sealing ring

摘要

The present invention relates to a miniature microphone assembly comprising a capacitive microphone transducer comprising a microphone electrical contact or terminal, a microphone carrier comprising a carrier electrical contact or terminal formed on a first surface thereof, and an integrated circuit die comprising a die electrical terminal operatively coupled to signal amplification or signal conditioning circuitry of the integrated circuit die. The first surface of the microphone carrier comprises a first electrically conductive path surrounding the carrier electrical contact or terminal.
