Abstract

A binaural hearing instrument and an earpiece for the binaural hearing instrument are enabled for broadband wireless data transmission to a further binaural hearing instrument. Wireless broadband binaural data transmission with high bandwidth and low resource requirement is afforded, while the devices can be manufactured easily and inexpensively. The hearing instrument has a housing, a signal processor, a receiver and an antenna for binaural data transmission. The housing can be worn at least partly in an auditory canal. A distal section houses the signal processor and the receiver. A proximal section adjacent to the eardrum and separated spatially from the proximal section houses the antenna. The antenna is disposed between the receiver and the sound outlet as far in the auditory canal as possible. The distance between the antennas of the two binaural hearing instruments is reduced compared with conventional positioning and the bit error rate is significantly improved.

First claim

The invention claimed is:

1. A hearing instrument, comprising:
a housing configured for partial or complete insertion into a human auditory canal of a user, said housing having a distal section and a proximal section formed as separate units, said proximal section being spatially separated from said distal section and configured for placement adjacent the eardrum;
a signal processing facility and a receiver disposed in said distal section of said housing;
an antenna disposed in said proximal section of said housing;
an electrical conductor for actuating said antenna, said electrical conductor interconnecting said distal section and said proximal section;
said proximal section of said housing having a diameter and a contour for enabling said proximal section to be positioned in a region of a second bend or deeper in the human auditory canal;
a sound tube connecting said distal section to said proximal section for conducting sound from said distal section, through said proximal section and to the eardrum, said sound tube carrying said antenna and projecting through said antenna; and
said sound tube and said electrical conductor forming a connection between said distal section and proximal section to enable said housing to adjust to a shape of the auditory canal and the second bend formed in the auditory canal, and wherein a shape of said proximal section and an arrangement of said antenna in said proximal section are adapted to the auditory canal to assure that, when said proximal section is inserted in the auditory canal, said antenna is aligned with a respectively opposite auditory canal of the user wearing the hearing instrument.

2. The hearing instrument according to claim 1 , wherein said antenna is formed with a feed-through having a distal opening and a proximal opening and defining a sound channel, and wherein said distal opening of said feed-through is connected through said sound tube to an output of said receiver.

3. The hearing instrument according to claim 1 , wherein said distal and proximal sections together form an in-the-ear housing to be worn in the auditory canal.

4. The hearing instrument according to claim 1 , wherein said proximal section includes a flexible dome or an expandable element for fixedly positioning said proximal section in the auditory canal.
