Abstract:
A personal listening device including at least one direct-radiating balanced-armature audio transducer and at least one substantially enclosed, indirect-radiating, or tube-coupled balanced-armature transducer. The tube-connected transducer emits sound waves which pass through a hole, slot, tube or bore before entering an airspace near the eardrum of a user, while the direct-radiating transducer emits sound waves directly into the airspace adjacent the indirect-radiating transducer or tube, which airspace is contiguous with the airspace near the eardrum of the user.
