  • the insert 25 acts as a pollution protection and is light thanks to its preferably water-repellent coating cleanable.
  • a cylindrical flat battery or a suitably shaped battery 33 is inserted, such that the axis of the battery cylinder, with its end faces 33 u and 33 o , at least substantially, coaxial with the longitudinal axis A. of the main body lies.
  • a first resilient contact 35 is provided, a second 37 resiliently contacts the side surface of the battery 33.
  • the battery compartment 29 is in a closed position with one to the axis A quer Dodge cover 39 closable, which at the base housing 3, at 41, swivel or bayonet bearings or on the battery compartment 29.
  • This transverse positioning of the battery 33 on the hearing aid has significant advantages:
  • the closed by the lid 39 Area is relatively large, which - as will be explained later - can be used further.
  • the battery compartment cover continues 39 is located at the lowest point of the device and the Deckelstossstellen to the base housing 3 are transverse to the axis A, is a penetration of sweat into the battery compartment hardly critical.
  • the lid 39 carries no electrical contacts. Because the further essentially cylindrical interior of the body 3 exploited is virtually no unused, lost Room.
  • Swivel bearing 41 as shown in FIG. 1 can be unlatched or latched thereto.
  • it has in the following a locking lock 45, together with a resilient latch 46th
  • FIG. 4 the lid 39 is shown in FIG. 1 in an external view.
  • the locking lock 45 is from the outside only with a tool, such as a screwdriver, operable and has for this purpose, on a turntable 47, an engagement slot 49 on.
  • the board 47, which only when mounting the Locking lock 45 is installed on the hinged lid 39 is specifically colored, in two versions, e.g. Red and blue, with which this part serves as an indication of whether the each hearing device present a device for left or right Ear is.
  • the illustrated embodiment of the Battery compartment 29 in particular the fact that the battery flat cylinder coaxial with the axis A of the hearing aid, a another, significant advantage.
  • the hearing aid shown in Fig. 1 namely corresponds to a basic configuration.
  • the now acting as the actual battery compartment 29a with Battery 33 is now provided on the additional module 51 and, accordingly, the lid 39, e.g. removed from the base housing 3 and is latched on the additional module or engaged in a bayonet-like manner.
  • a plurality of such modules 51 am in in Fig. 1st illustrated basic module of the hearing aid are stacked.
  • the respective fixation of the additional modules 51 is preferably carried out with one provided on the modules 51 Einrastpartie 43a, analog to the hinge part 43 on the hinged lid 39, and an analogous to Snap member 46 formed on said hinged lid 39 Snap piece 46a or, with bayonet lock, by appropriate Insert and turn lock.
  • the assembly 15 includes, encapsulated in a speaker housing 53, the speaker assembly (not shown) with a speaker diaphragm.
  • the speaker assembly By schematically drawn at 55 coupling openings, the sound waves excited by the speaker membrane from the membrane-back space in the speaker housing 53 in the surrounding space U 53 , the speaker housing 53 are coupled. From the membrane front space, the acoustic signals are - as shown by the arrow S - coupled to the apparent in Fig. 1 transmission channel 11.
  • the speaker housing 53 is supported on all sides in resilient, preferably in rubber-elastic bearings 57, substantially free swinging. Due to the bearings 57, the relatively large space U 53 is defined between loudspeaker housing outer wall and an encapsulation 59, which leads to a considerable increase in the bass tones.
  • the membrane-rear resonance space is increased by the space U 53 many times. So that the space U 53 is acoustically fully effective, the enclosure 59 and its holder 61 are tightly connected.
  • the encapsulation 59 more preferably acts as a magnetic shielding housing and is this preferably made of ⁇ -metal. It is cup-shaped and is on the holder 61, as a plastic carrier part trained, tightly hooked. Between encapsulation 59, holder 61 on the one hand and speaker housing 53 are mentioned resilient, preferably rubber-elastic, bearings 57 stretched.
  • Fig. 8 the illustrated acoustic coupling is shown in principle purely.
  • the diaphragm 54 of the loudspeaker in the housing 53 defines in said housing a first space R 1 which is coupled to the acoustic output of the hearing aid as shown at S and a second R 2 connected via one or more openings 55 to the one between encapsulation 59 and housing 53 formed space U 53 is coupled.

As schematically with the spring contact 69, with respect to the basic housing 3 fix, and the Bridging contact 70 shown on the carriage 67 is through back and forth sliding the carriage via button 63 the device switched on and off.
  • a continuous groove 72 is incorporated, through which a housing-3 fixed contact pill 73 protrudes.
  • resilient contact portion 75 which is preferably made as a keyboard element made of rubber-elastic, at least partially electrically conductive plastic, as known, for example, remote control keyboards.
  • the operation switch 31 acts both as an on / off slide switch and additionally, in the on position, as a toggle switch, with which - for example, for rapid individual gain adjustment - in steps on the electronics unit 27 as shown in FIG. 1 is acted upon.
  • the basic housing 3 formed by a bent, correspondingly shaped pipe part.
  • this part 3 is made in one piece formed, preferably made of plastic and is not like otherwise common in the construction of such hearing aids, along in Fig. 5 with M registered generatrices, separable in two shells.
  • This also includes the assembly of the individual units into the basic housing 3: they are simply inserted into the tube, which is much easier than an assembly opened cups.
  • Another advantage of a tubular, one-piece embodiment is their much greater stability opposite a split housing. This is a reduction the housing wall thickness and thereby a reduction of the same possible, or for a given external volume an increase in the usable interior volume.
  • Fig. 1 it can be seen, especially in the preferred one-piece design of the base housing 3, that the individual units, in particular 11, 15, 27, 29 and / or 51, by axial, sequential insertion into the Base housing 3 are assembled.
  • Shape of the housing 3 with appropriate guides ensures a quick, accurate Positioning, whereby the mutual electrical contact solderless between the electrically operated units, done by means of resilient contacts. So that can beforehand tested and measured and measured without fear of being impaired, it has been assembled become. This assembly can be easily automated become.
