Actuator systems for oral-based appliances utilizing transducers which are
attached, adhered, or otherwise embedded into or upon a dental or oral
appliance to form a hearing aid assembly. Such oral appliances may be a
custom-made device which receives incoming sounds and transmits the
processed sounds via a vibrating transducer element. The transducer
element may utilize electromagnetic or piezoelectric transducer
mechanisms and may be positioned directly along the dentition or along an
oral appliance housing in various configurations.
