Abstract:     Hearing aid, comprising at least one microwave generator (9) which receives an electrical signal from, for example, a microphone (27) and generates a frequency-modulated electrical signal composed of bursts, the burst frequency depending on the sounds picked up by the microphone, which frequency-modulated signal is fed to a radiator (25, 26) which generates microwave radiation (28) made up of bursts, at least the radiator (25, 26) of the hearing aid being situated in the ear canal (11) of a hearing organ and the microwave generator (9) being designed in such a way that the burst frequencies are at least virtually equal to the sound frequencies of the sounds picked up by the microphone.

First Claim:
Show all claims
    Claims 1. Hearing aid, comprising at least one microwave generator which receives an electrical signal from a sound transducing unit, for example a microphone, and generates a frequency-modulated electrical signal composed of bursts, the burst frequency depending on the sounds picked up by the sound transducing unit, which frequen cy-modulated signal is fed to a radiator which generates microwave radiation made up of bursts, characterized in that at least the radiator (25, 26) of the hearing aid is situated in the ear canal (11) of a hearing organ and the microwave generator (9) is so designed that the burst frequencies are substantially equal to the sound frequencies of the sounds picked up by the sound transducing unit (27).

Description
Expand description
+ Hearing aid based on microwaves The present invention relates to a hearing aid, comprising at least one microwave generator which receives an electrical signal from a sound transducing unit, for example a microphone,- and generates a frequency-modulated electrical signal composed of bursts, the burst frequency depending on the sounds picked up by the sound transducing unit, which frequency-modulated signal is fed to a radiator which generates microwave radiation made up of bursts.
    Such a hearing aid is disclosed by US Patent Specification US-A-4,877,027. A device is described therein in which a deaf person is irradiated with microwaves having a pattern which is such that when they arrive at the brain of said deaf person, they excite a hearing sensation. The device is composed of a microphone or the like for converting sound waves into an electrical audio signal.
