Fig 4 Traditionell hörapparat med hela förstärkningen etc i hörselgången och utrustad med batterie laddare enligt uppfinningen.Fig. 4 Traditional hearing aid with the entire amplification etc in the ear canal and equipped with a battery charger according to the invention.
O Pêt faktiska förhållande i hörapparatens vardagliga Omglvulng, som uppfinningen använder sig av, är följande: ígïíeš ::::šeÉ:r:::::lEång är temperaturen ba f37%2_ och i '_ ra ar temperaturen vanligen klart lägre än +27°C. Temperaturskilnaden på normalt mer än l0°C kan användas för att med termoelektrisk metodik alstra laddningsenergi.The actual conditions in the everyday environment of the hearing aid used by the invention are as follows: ígïíeš :::: šeÉ: r ::::: lEång the temperature is ba f37% 2_ and in '_ ra the temperature is usually clearly lower than + 27 ° C. The temperature difference of normally more than 10 ° C can be used to generate charge energy with thermoelectric methodology.
Mängden energi som går att ta ut ur ett kvicksilver- batteriet enligt exemplet ovan (1,4 V / 260 mAh) innan hörapparaten upplevs som oanvändbart svag torde vara under l V x 260 mAh eller under 0,25 Wh. Den mängden energi räcker ca 50 timmar. Den kontinuerliga effekten är sålunda av storleksordningen 0,005 W. Ett så litet utflöde borde utan svårighet kunna kompenseras med rätt typ av termo- elektrisk utrustning.The amount of energy that can be taken out of a mercury battery according to the example above (1.4 V / 260 mAh) before the hearing aid is perceived as unusably weak should be below 1 V x 260 mAh or below 0.25 Wh. That amount of energy lasts about 50 hours. The continuous power is thus of the order of 0.005 W. Such a small outflow should be easily compensated with the right type of thermoelectric equipment.
Ett utföringsexempel på en anordning enligt uppfin- ningen beskrivs nedan i anslutning till den bifogade rit- ningen på vilken: Fig 1 visar en konventionell hörapparat .med detaljerna: Ljudomvandlarhölje 1 med invändig batteri- hållare, hörselgångsenhet 2 och Ljudtransportslang 3 (Jämför detaljbeskrivning på sid 1, andra stycket) medan: Üs14:a34i Fig 2 visar samma baskonstruktion kompletterad med Yttre temperaturkännare 4, och Hörselgångstemperaturkännare 5 båda med två tunna kopplingsledningar in till Kombinerad laddningsstyrning och eventuell spänningsomvandlare 6 placerad inne i det förstorade nöljet bakom_oärarens öra.An embodiment of a device according to the invention is described below in connection with the accompanying drawing, in which: Fig. 1 shows a conventional hearing aid with the details: Sound converter housing 1 with internal battery holder, hearing aid unit 2 and Sound transport hose 3 (Compare detailed description on page 1, second paragraph) while: Üs14: a34i Fig. 2 shows the same basic construction supplemented with Outer temperature sensor 4, and Hearing passage temperature sensor 5 both with two thin connection lines into Combined charge control and any voltage converter 6 placed inside the enlarged needle behind the ear.
Spänningsomvandling kan Eli nödvändigt om man väljer att samla termisk energi med konventionella lödpunkter för två metaller (s.k."Thermo couples”).Dessa ger låg spänning men relativt stor ström. Fig 3 visar den kompletta aparaten un- der laddning i en termostatstyrd nätansluten liten Värme- låda 7, i vilken temperaturen styrs att vara l5°C högre i den del,där hörselgångstemperaturkännaren 5 ligger, än i resten av lådan.Voltage conversion can Eli necessary if you choose to collect thermal energy with conventional solder points for two metals (so-called "Thermo couples"). These provide low voltage but relatively large current. Fig. 3 shows the complete device while charging in a thermostat-controlled mains-connected small Heat box 7, in which the temperature is controlled to be 15 ° C higher in the part where the ear canal temperature sensor 5 is located, than in the rest of the box.
Alternativ tillämpning av grundprincipen enligt denna uppfinning visas i Fig 4. Hela hörapparaten befinner sig inne i hörselgången. Denna_typ av apparater-finns redan på marknaden, dock utan den batteriladdande funktionen. De har ofta en liten ”stropp” med en liten kula i änden stickande rätt ut ur hörselgången. Stroppen användes när bäraren önskar ta ut hörapparaten. Denna funktion och den termoelektriska kan naturligtvis kombineras. -o0o-Alternative application of the basic principle according to this invention is shown in Fig. 4. The entire hearing aid is located inside the ear canal. This type of device is already on the market, but without the battery-charging function. They often have a small "strap" with a small ball at the end sticking right out of the ear canal. The strap is used when the wearer wishes to remove the hearing aid. This function and the thermoelectric can of course be combined. -o0o-
