Description

DESCRIPTION

The present invention relates to a hearing aid with at least two sound transducers and a hearing aid amplifier, each sound transducer being arranged in a soundproof chamber and being electrically connected to the hearing aid amplifier.

Hearing aids are known, e.g. from CH-PS No. 539 375 in which the sound transducers are positioned in the housing by means of rubber caps or tensioning straps in order to stabilize the reference position which the transducer occupies in the housing. Sometimes the converters are mounted on a chassis together with the amplifier. This block is inserted into the housing shells. In order to keep the airborne sound emitted by the listener and the structure-borne sound away from the microphone at higher amplifications and sound pressures, very complex methods must be used in terms of construction and production technology, e.g. Encapsulate the receiver or install a metal wall between the transducers. It is also known to improve the tightness by applying adhesive to the joints of the housing shells. However, the measures represent tool technology

and high demands on assembly technology and the result is unsatisfactory.

The aim of the invention is to provide a hearing aid in which the disadvantages mentioned above are eliminated.

According to the invention, this aim is achieved by the characterizing features of patent claim 1.

The advantage achievable with the invention can be seen in the fact that, in addition to the structure-borne noise, the airborne sound emitted by the listener is also held off by the microphone.

In one embodiment, the sound transducers are arranged in a common receiving part which has two compartments, each with a sound opening.

This has the advantage that the sound transducers can be manufactured, measured and calibrated separately with the receiving part as a module.

This also means that the modules can be installed automatically during final assembly.

In another embodiment, the receiving part is provided with a wall made of non-metallic material with an electromagnetic shield.

This has the advantage that when using an induction coil, the problem of feedback with the receiver can be significantly reduced.

In a further embodiment, the hearing aid amplifier is arranged in one part of the hearing device housing and the sound transducers in a second part of the hearing device housing, and the two parts are electrically and mechanically detachably connected.

The subdivision into an acoustic part and an amplifier part results in the advantages that if a fault occurs in one part, this can be remedied quickly by exchanging it, and that the listening properties can be adapted in a simple manner by exchanging the acoustic part.

In a further embodiment with an otoplastic, the otoplastic and the hearing device housing are detachably connected via a support hook. The support hook is designed as an electrical connection device between the sound transducers and the hearing aid amplifier. At least one sound transducer is arranged in the otoplastic.

This results in significant audiological advantages.

In an advantageous further development, however, the sound transducer is arranged in a receiving part, which is designed as a structural unit and is mounted in the otoplastic. In order to connect the sound transducers to the hearing aid amplifier, a contact arrangement is provided on the component.

This has the advantages that the break through connecting wires, e.g. when removing the earmold from the ear, unnecessary susceptibility to interference is eliminated and cleaning the assembly is much easier.

In the following, embodiments of the subject matter of the invention are explained in more detail with reference to the accompanying drawings.

FIG. 8 is a view of part of a contact arrangement for the acoustic module shown in FIG. 7.

1 shows a hearing device which contains a housing 1 in which two sound transducers, a receiver 2 and a microphone 3, and a hearing device amplifier 4, which is usually designed as a separate component and is inserted into the housing 1.

As can be seen from this Fig. 1, the sound transducers 2, 3 are arranged in receiving parts 5, 6. The receiving parts 5, 6 are designed as tubular housings, each of which has a sound nozzle 7, 8 forming a sound opening 7, 8 on one end face and is closed off on the other end face by a plate 11, 12, so that a chamber 13, 14 is formed. The sound transducers 2, 3 are arranged in these chambers 13, 14 and positioned by a soft bearing 15 or a suspension element 16. The sound connectors 17, 18 of the sound transducers 2, 3 are each connected to the sound connectors 9, 10 via flexible formwork cables 19, 20. 1 also shows, the sound connector 9 of the receiving part 6 for the microphone 3 protrudes freely from the housing 1 while the sound connector 10 of the receiving part 5 for the receiver 2 protrudes from the housing 1 and carries a carrying hook 21.

As already mentioned, the receiving parts 5, 6 are closed by a plate 11, 12. Contact elements 22 are provided on the outside of the plates 11, 12 and are connected to the converter connections 24 via electrically conductive wires 23. The plates 11, 12 can have a number of contact elements 22 adapted to the corresponding sound transducer 2, 3 or a standardized number of contact elements 22. Instead of the electrically conductive wires 23, other suitable connecting elements, e.g. those which have a layered structure alternately consisting of electrically conductive and electrically insulating layers can be used.

Instead of the plates 11, 12, the receiving part 5, 6 can also be closed off by a wall part which is formed in the housing 1. Furthermore, there is also the possibility of providing the opening for inserting the sound transducers into the receiving parts 5, 6 in the walls of the tubular housing, which are then covered by the housing 1.

In order to connect the sound transducers 2, 3 to the hearing aid amplifier, mating contact elements 25 are provided in the housing 1, which can be brought into contact with the sound transducers 2, 3 with the contact elements 22 when the receiving parts 5, 6 are inserted.

2 shows another embodiment of the receiving part. This receiving part is essentially the same as the receiving parts shown in FIG. 1, the same features being identified by the same reference number. In contrast to the receiving part according to FIG. 1, this receiving part has a conical sound connector 26. In order to hold this receiving part securely in the housing 1, the opening for the sound connector 26 in the housing 1 or in an intermediate element which protrudes from the housing and carries the support hook is also conical.

FIGS. 3 and 4 show further embodiments of the receiving part with the sound transducers 2, 3 inserted therein. As can be seen from these figures, the sound transducers 2, 3 are arranged in a common receiving part 30, which has two compartments 31, 32 (FIG. 3) or three compartments 33, 34, 35 (Fig. 4). It is pointed out in advance that the compartments are covered by a cover part (not shown) or by the wall of the housing 1, thereby forming chambers in which the sound transducers are then enclosed.

As can be seen from FIG. 3, the sound transducers 2, 3 are each arranged in a compartment 31, 32. The compartments 31, 32 have a molded-on sound connector 36, 37. Flexible hose lines 19, 20 are inserted in the sound connector 36, 37 in a form-fitting manner, which are connected to the sound connector 17, 18 of the sound transducer 2,

3 are raised and determine the sound opening 7, 8. As with the receiving parts according to FIG. 1, contact elements 22 are provided on an outer side of the receiving part 30 and connected to the sound transducer connections 24 in the same way.

The embodiment shown in FIG. 4 differs from that shown in FIG. 3 in that, in addition to the two compartments 33, 34, a third compartment 35 is provided for the sound transducers 2, 3. In contrast to the receiving part 30, in which the sound connectors are connected to the sound transducers 2, 3, in the receiving part according to FIG. 4 only one sound connector 37 of the receiving part is connected to a sound transducer 3, while the other sound connector 36 opens into the third compartment 35 . The sound connector of the second compartment 34 in which the other sound transducer 2 is arranged opens into this third compartment 35. This third compartment 35, which forms a chamber after closing in the manner described above, forms an acoustic filter or can be provided with an acoustic filter (not shown).

4 has contact elements (not shown) on the outside, which e.g. as can be formed in the receiving part 30 of FIG. 3.

The receiving parts shown in FIGS. 1-4 can consist of a metallic or non-metallic material. Plastic has proven to be an advantageous material. 2, the tubular section and the molded sound connector made of rubber. In this case, the wall is made thicker in order to achieve a damping and insulating effect. The use of rubber means that the flexible hose line can be dispensed with and the sound connector 17, 18 of the sound transducer 2, 3 can be inserted into the sound opening 7, 8 in a form-fitting manner.

A shield (not shown) can be provided for electromagnetic shielding of the sound transducers 2, 3, which shield is formed from metallic half-shells (not shown) enclosing the receiving part or a suitable coating on the outside of the receiving part.

5 shows another embodiment of the hearing aid, which consists of two parts 40, 41 releasably connected to one another. The sound transducers are arranged in one part 40 and the hearing aid amplifier in the other part 41. In order to connect the sound transducers to the hearing aid amplifier, contact elements 42 are provided, the design of which is not explained in detail. As a result, the hearing aid is divided into an actual acoustic module and an amplifier module, which results in advantages in terms of maintenance and application technology.

6 shows a hearing aid with an earmold 50, which is detachably connected to the hearing aid via a support hook 51, the hearing aid amplifier being arranged in the housing 1 and the sound transducers in the earmold 50. The support hook 51 is designed as a connecting element on both

Ends is provided with a plug contact arrangement 52, which can be designed differently and of which only one is shown.

The sound transducers arranged in the otoplastic 50 are combined to form an acoustic module, as shown in FIG. 7.

As shown in Fig. 7, the acoustic module contains a first receiving part 53, e.g. made of plastic, which is tubular, has a sound opening 54 on one end and is open on the other end. The one transducer 2, i.e. the receiver is arranged within the receiving part 53 such that the sound connector 18 of the sound transducer 2 projects into the sound opening 54 and is held in the receiving part 53 by the soft bearing 15.

A second receiving part 55 is arranged in the region of the open end face and bears against a shoulder 56 formed in the first receiving part 53. The second receiving part 55 is cup-shaped and inserted into the first receiving part 53 in such a way that its bottom rests on the shoulder 56. This arrangement forms a soundproof chamber 57 in which the first sound transducer 2, i.e. the handset is down. A plate 58, which is held on the circumference in the first receiving part 53 and abuts the edge of the second receiving part 55, thus forms a second soundproof chamber 59, in which the other sound transducer 3, i.e. the microphone lies and closes the acoustic module flush with the edge of the first receiving part 53. A sound opening 60 is formed in the plate 58, into which the sound connector 18 of the sound transducer 3 projects. The sound opening 54 is closed off by a cap 61 in order to protect the sound opening 54 and thus the sound connector 17 from contamination. Holes 62 are formed in the cap.

As shown in FIG. 7, this acoustic module is provided with a contact arrangement 63 into which the plug contact arrangement 52 can be inserted in order to connect the sound transducers 2, 3 to the hearing aid amplifier via the support hook 51.

The contact arrangement 63 consists of two flexible, band-shaped carriers 64 and three conductor tracks 65, which are applied to one side of the carrier 64. At one end, the band-shaped carrier 64 has a section 70 which is provided with contact elements 67 which are in contact with the converter connections 24. For this purpose, the contact elements 67 have been led out through the carrier 64 to the other side.

At the other end of the carrier 64, the conductor tracks 65 are widened and form contact elements 68 which can be brought into contact with the plug contact arrangement 52 of the support hook 51. As shown in FIG. 7, the carriers 64 are arranged at a distance from one another in order to make the plug contact arrangement 52 as small as possible. An opening 69 is provided in the plate 58, through which the plug contact arrangement 52 of the support hook 51 can be brought into contact with the contact arrangement 63.
