Embodiment Construction

[0036] exist figure 1A perspective view of an HDO hearing aid tool is schematically shown in . It comprises a housing 11 in which the electronic components of the hearing aid, such as a microphone, a signal processing unit, a receiver and a battery, are arranged. The housing 11 is connected to a hook 12 which serves, on the one hand, to enable the housing to be hooked behind the user's ear and to wear it, and on the other hand, to serve as an interface for a tube (acoustic tube). The operating element 13 , which may be designed as a push switch, a rocker switch or a rotary wheel, is used to enable user inputs which relate, for example, to switching on / off or adjusting operating parameters of the hearing aid 10 . On the lowermost end of the housing 11 there is a battery compartment 14 which is only partly visible in the figures.

Abstract

The invention relates to an HdO hearing aid worn behind the ear with a housing and a carrying hook. The carrying hook and the housing are connected through an insertion connection device. A clip is designed to fix the insertion connection device. Grooves are respectively arranged in the carrying hook and the housing. The grooves are designed to accommodate the clip. The grooves are oriented to be unparallel with the insertion direction of the insertion connection device, so that when the carrying hook and the housing are completely in inserted connection with each other, the grooves are aligned with each other. The clip is guided in simultaneously the grooves. The insertion connection device between the carrying hook and the housing is fixed through the clip, so that fixing such as screw fixing which is more expensive and more space-consuming is advantageously avoided. By means of fixation realized by the clip and the grooves, rotation angles which can be freely selected between the carrying hook and the housing can be additionally realized. According to needs, the grooves can be formed in a mode of enabling the fixed carrying hook to rotate, not to rotate, rotate limitedly or rotate unlimitedly.

Description

technical field [0001] The invention relates to a hearing aid (HdO) for wearing behind the ear with a plug-in connection between a housing and a hook as well as the housing and the hook of such a hearing aid. Background technique [0002] The hearing aid can be designed, for example, as a hearing aid. Hearing aids are used to provide a hearing impaired person with an ambient sound signal that is processed and amplified for compensation or treatment of hearing loss. The hearing aid basically consists of one or more input converters, signal processing means, amplification means and output converters. The input transducer is typically an acoustic receiver (eg a microphone) and / or an electromagnetic receiver (eg an induction coil). The output transducer is generally realized as an electro-acoustic transducer (such as a microspeaker) or as an electromechanical transducer (such as a bone conduction earphone). It is also called a headset or receiver. The output transducer produ...
