Abstract
Provided herein is a device for improved induction of sound by electromagnetic radiation, comprising a carrier layer; a first substance having a reflective property with respect to electromagnetic radiation having a predetermined wavelength spectrum; and a second substance having an absorptive property with respect to electromagnetic radiation having said predetermined wavelength spectrum; wherein said first substance is disposed in a region between said carrier layer and said second substance. Furthermore, a corresponding method is provided.
Claims21
A vibratable auditory device, comprising:
- a carrier layer;
- a first substance having a reflective property with respect to electromagnetic radiation having a predetermined wavelength spectrum;
- a second substance having an absorbing property with respect to the electromagnetic radiation having the predetermined wavelength spectrum;
- wherein the first substance is disposed in a region between the carrier layer and the second substance.
A method for mechanical excitation of an eardrum, comprising:
- using a vibratable auditory device to excite the eardrum, wherein the vibratable auditory device comprises
- a carrier layer;
- a first substance having a reflective property with respect to electromagnetic radiation having a predetermined wavelength spectrum;
- a second substance having an absorbing property with respect to the electromagnetic radiation having the predetermined wavelength spectrum;
- wherein the first substance is disposed in a region between the carrier layer and the second substance,
- wherein the eardrum is excited by the vibratable auditory device via the electromagnetic radiation.
A method for mechanical excitation of a tympanic membrane or a vibratable structure of a skull other than the tympanic membrane by electromagnetic radiation, comprising:
- attaching a vibratable auditory device to the eardrum or the other vibratable structure of the skull, wherein the vibratable auditory device comprises
- a carrier layer;
- a first substance having a reflective property with respect to electromagnetic radiation having a predetermined wavelength spectrum;
- a second substance having an absorbing property with respect to the electromagnetic radiation having the predetermined wavelength spectrum;
- wherein the first substance is disposed in a region between the carrier layer and the second substance;
- irradiating the device with the electromagnetic radiation having the predetermined wavelength spectrum.
