Abstract
An assembly of a receiver and a microphone, such as for positioning in an ear canal of a person. The receiver and microphone are provided in an overlapping relationship to take up less space while being able to emit sound in one direction and receive sound from that direction. When the assembly if for use deep inside the ear canal of a person, the microphone may be very small, as it is exposed to very high sound levels.
