Claims (10)
1. Transducer (10) til et høreapparat, hvilken transducer omfatter et hus (22), som har: - et vægafsnit (22’), som definerer en udvendig overflade og en indvendig overflade, idet den indvendige overflade definerer i det mindste en del af et første kammer (12), idet vægafsnittet (22’) omfatter en åbning (18, 28) fra den indvendige overflade til den udvendige overflade, - en membran (20), som har en første overflade, som definerer i det mindste en del af det første kammer (12), - et fugttransporterende element (30, 31, 33), som er placeret i åbningen (18, 28) og strækker sig i det mindste fra den indvendige overflade til den udvendige overflade til transport af fugt fra den indvendige overflade til den udvendige overflade, hvori det fugttransporterende element (30, 31, 33) omfatter: - én eller flere kapillærkanaler (31) eller - en fiber (33) eller - et hydrofilt element.
2. Transducer (10) ifølge krav 1, hvori det fugttransporterende element (30, 31, 33) omfatter en udvendig del (34), som er placeret ved eller uden for den udvendige overflade, hvori den udvendige del er fremstillet af samme materiale og har samme struktur og/eller samme vandtransporterende evne som en øvrig del af det fugttransporterende element.
3. Transducer (10) ifølge krav 2, hvori den udvendige del (34) omfatter et vandabsorberende element.
4. Transducer (10) ifølge krav 2 eller 3, hvori den udvendige del (34) omfatter et hydrofilt element.
5. Transducer (10) ifølge et hvilket som helst af kravene 2-4, hvori den udvendige del (34) har en form, som, i forhold til et tværsnit af åbningen, spreder sig ud i en retning væk fra huset.
6. Transducer (10) ifølge et hvilket som helst af kravene 2-5, hvori den udvendige del (34) er dækket af et åndbart element.
7. Transducer (10) ifølge et hvilket som helst af de foregående krav, hvori et forudbestemt område af den indvendige overflade ved eller omkring åbningen (18, 28) er hydrofilt, og hvor andre dele af den indvendige overflade er hydrofobe.
8. Høreapparat omfattende en transducer (10) ifølge et hvilket som helst af de foregående krav og et høreapparathus, hvilket høreapparathus har: - en første overflade og - en anden overflade over for den første overflade - en høreapparatåbning, som er konfigureret til at blive rettet ind i brugerens øregang, hvilken høreapparatåbning er placeret i den første overflade, idet åbningen (18, 28) er placeret i eller ved den anden overflade.
9. Høreapparat ifølge krav 8, hvori huset (22) er konfigureret til at have en forudbestemt retning i forhold til brugerens øregang, og hvori transduceren (10) er placeret inden for høreapparathuset, således at åbningen (18, 28) i det første kammer (12) er placeret i eller ved en lavere overflade af det første kammer.
10. Høreapparat ifølge krav 9, hvori det fugttransporterende element (30, 31, 33) strækker sig fra transduceråbningen (18, 28) til høreapparatåbningen.
