Problems solved by technology

The efficiency of the energy driving the magnet is less than ideal because the intensity decreases rapidly over distance
Also, the location of the driver coil close to the magnet can cause user discomfort in some situations
There is also a need to align the driver coils with the permanent magnets, which in some cases leads to less than ideal performance

Embodiment Construction

[0114] Embodiments of the present invention may provide hearing devices that are directly coupled to at least one of the eardrum or ossicles, allowing the user to perceive sound with minimal occlusion and feedback and improved audio signal transmission. The systems, devices and methods described in this application may find application for hearing devices, such as open canal hearing aids. While specific reference is made to hearing aid systems, embodiments of the invention may be used in a variety of applications where audio signals are received, eg, optically or electromagnetically, and converted into mechanical outputs.

[0115] As used in this application, the umbilicus of the eardrum surrounds the central portion of the eardrum that is coupled to the malleus and extends most medially along the ear canal.

[0116] figure 1 The anatomy of the ear is shown along with an audio signal transmission system 10 comprising an output transducer assembly 100 coupled to the ear accor...

Abstract

A device to transmit an audio signal to a user comprises a transducer and a support. The support is configured for placement on the eardrum to drive the eardrum. The transducer is coupled to the support at a first outer location to decrease occlusion and a second inner location to drive the eardrum. The transducer may comprise one or more of an electromagnetic balanced armature transducer, a piezoelectric transducer, a magnetostrictive transducer, a photostrictive transducer, or a coil and magnet. The device may find use with open canal hearing aids.
