1. A microphone assembly comprising:
a form-factor adapter housing including an interface opening and an outer acoustic port;
an internal microphone assembly disposed at least partially within the form-factor adapter housing, the internal microphone assembly including:
an internal housing having:
a base;
an internal housing cover mounted on the base; and
an internal acoustic port;
a microelectromechanical systems (MEMS) motor disposed in the internal housing;
an integrated circuit disposed in the internal housing, the integrated circuit electrically coupled to the MEMS motor; and
a plurality of electrical interface contacts disposed on the base, the plurality of electrical interface contacts electrically coupled to the integrated circuit; and
an adapter interface located at the interface opening and comprising a plurality of external host device interface contacts electrically coupled to the plurality of electrical interface contacts, the plurality of external host device interface contacts exposed to an exterior of the microphone assembly,
wherein the MEMS motor is acoustically coupled to the outer acoustic port via a sound path between the form-factor adapter housing, the internal housing, and the internal acoustic port.
 
9. A microphone assembly comprising:
a form-factor adapter housing including an interface opening and an external acoustic port;
an internal microphone assembly disposed at least partially within the form-factor adapter housing, the internal microphone assembly comprising:
an internal housing having an internal acoustic port and a plurality of electrical interface contacts;
a microelectromechanical systems (MEMS) motor disposed in the internal housing; and
an integrated circuit disposed in the internal housing, the integrated circuit electrically coupled to the MEMS motor and to the plurality of electrical interface contacts; and
an adapter interface located at the interface opening and comprising a plurality of external host device interface contacts electrically coupled to the plurality of electrical interface contacts, the plurality of external host device interface contacts exposed to an exterior of the microphone assembly,
wherein the internal acoustic port is acoustically coupled to the external acoustic port.
