Abstract
A microphone assembly includes a housing including a sound port and an external-device interface having a plurality of electrical contacts. An acoustic transducer, such as a MEMS microphone, is disposed in the housing and is in acoustic communication with the sound port. An electrical circuit is disposed in the housing that is electrically coupled to the acoustic transducer and to electrical contacts on the external-device interface. A magnetic transducer including an electrical coil disposed about a core, such as a telecoil or charging coil configuration, is fastened to the housing. The electrical coil having leads, at least one of the leads electrically terminated at a coil contact of the housing.
