A microphone is provided. The microphone has a housing; an acoustic port located in the housing; a substrate coupled with the housing; an integrated circuit positioned onto the substrate; and two or more MEMS transducers mounted on the substrate wherein the transducers are connected in parallel.

Microphone having multiple transducer elements

A receiver is provided having a balanced armature motor mechanically interconnected to a displaceable diaphragm component. A front volume changes as the displaceable diaphragm component moves. The front volume is connected to a port. A rear volume changes oppositely to the front volume as the displaceable diaphragm moves. An acoustic channel connects to the port and is also connected to a sound outlet. The sound outlet allows acoustic energy to exit from the acoustic channel. A first acoustic pressure is generated in the front volume as the balanced armature motor moves the diaphragm. The acoustic channel and the internal volume are divided by a common wall section, wherein the common wall section is defined by at least one of the walls of the housing which also provides a portion of at least one wall for the acoustic channel.
