Definitions
- Hearing aid with parts made of electrically conductive and at the same time sound insulating material
- hearing aids with external handset or hearing aids with rechargeable energy storage (for example) battery is growing in the number of external electrical connections.
- these external connectors of hearing aids are made as externally accessible electrical contacts made of gold-plated metal.
- the complexity and cost of these hearing aids increase significantly with an increasing number of ports. Examples are the numerous variants of audio inputs, programming connections and charging contacts for commercially available hearing aids.
- the present invention seeks to improve this situation.
- electrical contacts made of electrically conductive and at the same time sound-absorbing material without additional metal parts are provided on the outside of a hearing aid housing.
- the invention leads to a hearing aid with parts of electrically conductive and at the same time sound-insulating material, which at the same time as sound-insulating elements of the
- the hearing aid is equipped with parts of electrically conductive and at the same time elastic material, in particular with parts made of an elastic natural or plastic, which were admixed with electrically conductive particles during processing. It is particularly advantageous if the hearing device is equipped with parts made of electrically conductive and at the same time sound-insulating material to which pigments have been mixed during processing which contribute to the optical inconspicuousness of these parts in relation to their surroundings.
- sound-insulating is to be understood as meaning an acoustic, sealed connection based primarily on shock-absorbing and / or vibration-inhibiting properties.
- a hearing aid with parts of electrically conductive and at the same time sound-insulating material, which serve as a storage for components of the hearing aid, which should be acoustically shielded against sound transmission through these parts.
- the transducer bearings currently made of various rubbery materials, e.g. Silicone and currently meet mainly acoustic requirements - for example, in terms of sound insulation - meet.
- Transducers in this context are mainly listeners or microphones.
- the present invention now provides for these bearings-for example transducer bearings made of electrically conductive and at the same time sound-insulating material-to be produced from electrically conductive material (for example, conductive rubber) and thus an electrical contact to the outside of a hearing aid is available on top of that, not even as a such would be perceived and thus would also constitute a more cosmetically pleasing variant of an electrical contact.
- electrically conductive material for example, conductive rubber
- the combination of these two properties of electrical conductivity and sound insulation can be, for example, by an admixture of conductive
- the converter housings are often already electrically connected to the actual amplifier circuit (e.g., the microphone housings are largely grounded), even the extra connection from the externally accessible contact to the circuit board is eliminated. Because because the metal housing of the converter is already electrically on the reference potential ("ground” or GND) and the conductive elastic mass now also touches the housing, is on the outside of a conductive contact alone by the visible storage available.
- ground reference potential
- an embodiment of the invention provides for using this component as an electrical contact, for example with external converters or external switches.
- the internal connection to the hearing aid amplifier can in turn be made via electrically conductive earphone mounts or in this case by direct connection of an electrical line (2.B. soldering, welding, clamping, gluing ].
- the present invention thus has a number of advantages.
- Figure 1 shows a possible embodiment of the invention in a schematic manner. Due to the corresponding structure of a hearing aid, it would be possible, for example, to automatically detect the presence of a particular carrying hook.
- the external "switching element" (A) acts as electrical contact between the conductive microphone mounting (B) and the metal connection piece (C).
