Embodiment Construction

[0059] figure 1 Exemplary ear canal-mounted hearing subsystems 1 and 2 are shown. figure 1 The system processes sound signals from each of the two microphones 7 . The microphone 7 is placed in the opening or directly in the user's ear canal. Each of the systems 1-2 includes a battery 3, a signal processor 4, a transmitter 5, all of which may be housed in a housing that clips onto the ear and rests behind the ear between the pinna and the skull, or Optionally, it can be placed in the concha of the ear. The transmitter 5 is connected to a wire / antenna 6 which in turn is connected to a microphone 7 .

[0060] Each transmitter 5 sends information to a receiver 8 which activates a transducer 9 powered by a battery 10 . There may be a set of receiver 8, transducer 9 and battery 10 on each side of the head. This embodiment provides a bone conduction hearing aid device with externally located dual microphones placed at the entrance to or within the ear canal and an oral appliance c...

Abstract

The invention provides a bone conduction hearing device with an open-ear microphone. Systems and methods for transmitting an audio signal through a bone of a user includes receiving an audio signal from a first microphone positioned at an entrance or in a first ear canal; and vibrating a first transducer to audibly transmit the audio signal through the bone. A second microphone can be positioned in a second ear canal and the two microphones preserve and deliver inter-aural sound level and phase differences that naturally occur so that the user can perceive directionality.

Description

[0001] This application is a divisional application of an application with an application date of June 3, 2008, an application number of 200880112519.1, and an invention title of "Bone Conduction Hearing Device with a Naked Microphone". technical field [0002] The present invention relates to methods and devices for transmitting vibrations through tooth or bone structures in and / or around the oral cavity. Background technique [0003] The human ear can generally be divided into three regions: the outer ear, the middle ear, and the inner ear. The outer ear usually includes the pinna and the ear canal, which is the tube-like passage through which sound travels to the middle ear. The outer ear is separated from the middle ear by the tympanic membrane (eardrum). The middle ear usually includes three small bones called the ossicles, which form the mechanical conductors from the eardrum to the inner ear. Finally, the inner ear includes the cochlea, a fluid-filled structure cont...
