PERSONAL LISTENING DEVICE

摘要

A receiver module for a personal listening device includes a motor assembly and a housing. The motor assembly includes a movable armature. The housing defines a chamber and the housing is at least partially constructed of a biocompatible material. The motor assembly is directly disposed and exposed to the chamber without the obstruction of any intervening structure. At least a portion of the housing of the receiver module is allowed to be in contact with at least a portion of the pinna that is external to the ear canal. The chamber is divided into a front volume and a back volume.
