The hearing aid, in particular a behind-the-ear hearing aid (1, 2) comprises:
a first unit (1) comprising an amplifier (4), a part- the hook (3) - formed with a duct (16) and a space (8),
a second unit (2) comprising an electro-acoustic transducer (12), which second unit is intended to be worn in the ear,
A tubular element (15) for the mechanical connection of the two units (1, and 2, respectively), which tubular element accommodates connecting means (14) for electrically coupling the transducer (12) to (an output of) the amplifier (4).
<??>The duct (16) has such a diameter that, if the element (15) has not been secured inside the hook (3), the element (15) is axially slidable inside the duct (16). This enables the hearing aid to be adapted to the size of the ear of the person wearing the hearing aid. The connecting means (14) have such a length that even in the case of adaptation of the hearing aid to a big ear the electrical connection is still in tact or can be made. When the hearing aid is adapted to a smaller ear, the connecting means (14) are in fact too long. The space (8) is intended for taking up the excess length of the connecting means (14). |
