Definitions

• the invention relates to a hearing aid according to the preamble of
• BTE devices Hearing aids to be worn behind the ear, hereinafter referred to briefly as “BTE devices”, are usually constructed from two housing shells, with separating webs forming a plurality of mutually separate chambers inside the housing.
• the user must be accessible from the outside, as well as with the electronic circuit, as well as with a microphone and loudspeaker, and it is comparatively complex to adapt such a hearing aid to different techniques, ie to different functional features of the electronic circuit, which often requires a complicated exchange of the individual components inside the hearing aid.
• the invention has for its object to improve a generic hearing aid in that it is simple and inexpensive to manufacture. This object on which the invention is based is achieved by a hearing aid with the features of claim 1
• the invention proposes to use a so-called front plate, which is also referred to as a "faceplate” and which is known, for example, from the field of hearing aids to be worn in the ear.
• a hearing aid is known, for example, from DE 81 06 942 U1 or DE 297 23 569 U1 known, a hearing aid from "Patents abstracts of Japan, E- 489 March 13, 1987 VOI.11 / No.83," Custom ear fitting type hearing aid “JP-61-238 198 (A)” With such a “faceplate” can be seen, which is designed as a combination plate or multifunctional plate.
• a commercially available standard front panel can be used, which is usually for one
• the front panel being present in its previously customary, in contrast larger, dimensions compared to its dimensions which are required for use with BTE devices. This front panel can be easily attached to the
• housing shell of the BTE device to be manufactured placed on the technical components are accommodated by the housing shell. Then protruding edge areas of the front panel, which is usually made of plastic and is easy to machine, are milled.
• the assembly with the electronic components it can be advantageous to be able to guide the front panel through the assembly machines in its larger dimensions that have been customary up to now.
• inexpensive series production can take place in that the front panel is first produced with these larger dimensions, fitted with the electronic components and then inexpensively adapted to the contour of the housing shell of a BTE device, for example by an automated stamping or milling process , The excess material can be removed before connecting the front plate and housing shell, with optimal accessibility of the front plate and without risk of damage to the housing shell.
• the housing shell and the front plate can advantageously be releasably connected to one another, so that simple replacement defective components or a simple adaptation to other desired technological properties of the hearing aid can be done by a complete replacement of the front panel, so that, in particular due to the progressive miniaturization, laborious to carry out by hand
• Interventions in the hearing aid can be avoided and the assemblies can be changed quickly and easily.
• FIG. 1 to 3 a housing shell in different views
• FIG. 4 a commercially available front panel for hearing aids to be worn in the ear
• FIGS. 5 and 6 production steps for producing a hearing aid according to the invention.
• 1 denotes a housing shell, two projections 2 being indicated purely schematically at the lower end of the housing shell 1. It can be, for example, an on / off switch, a volume control, or a connecting piece for a sound tube or the like.
• FIG. 2 shows the narrow side of the housing shell 1 in a representation angled by 90 °.
• FIG. 3 shows the view of the housing shell 1 rotated by a further 90 °, the trough-like interior 3 of the housing shell 1, which serves to accommodate the technological components of the hearing aid, to be seen here.
• FIG. 4 shows a front plate 4, which in practice is referred to as a "phase plate” and as a multifunctional plate not only has a housing function or a covering function of a hearing device, but also the technological components of the hearing device wearing.
• a cover flap 5 of a battery compartment can be seen from the outside; on the rear side of the front plate 4, as compared to FIG. 4, the electronic circuit, a loudspeaker and possibly a microphone are arranged.
• the microphone is optionally understood as the term “hearing aid” referred to in this application not only meaning sound-amplifying devices, but also sound-generating devices, such as tinitus treatment devices, which do not have their own microphone.
• FIG. 5 shows how the front plate 4 is placed on the housing shell 1, the technological components being accommodated within the trough-shaped interior 3. Areas of the front plate 4 protrude beyond the outer contour of the housing shell 1, which are subsequently removed by hand or by machine, for. B. be milled away.
• FIG. 6 shows a hearing aid 6, as is obtained after the excess areas of the front plate 4 have been removed. It has the outer contour of the housing shell 1, the front plate 4 being preferably detachably connected to this housing shell 1, for example by a snap connection, but possibly also by a screw connection, so that in any case the “technology module” can be removed quickly Shape of the front panel 4 can be done and appropriate repairs or adjustments can be carried out in a simple and quick manner.
• a hearing aid 6 according to the invention can also be produced in that before the assembly step, in which the front plate is connected to the housing shell 1, the front plate is brought to the contour adapted to the housing shell. This can be done directly by a shape adapted to the housing shell during the manufacture of the front panel, so that none
• Post-processing especially no superfluous removal Areas of the front panel is required, or this adjustment can be done by post-processing before connecting the front panel to the housing shell.
• Such an adaptation can also include the arrangement of connecting means on the front panel, for example for screwing or clipping, possibly also the creation of connecting surfaces for gluing, ultrasonic welding or the like.
• the front panel with the housing shell.
