Claims (15)

1. Akustikenhed, som udbreder sig i x, y og z retningerne, hvor akustikenheden omfatter 1) en første og en anden lydgiverenhed af typen med bevægeligt armatur, hvilke enheder er rumligt forskudt i forhold til hinanden i x-retningen, hvorved de skaber områder med fri og tilgængelig plads og 2) én eller flere mikrofonenheder, som er placeret i områderne med fri og tilgængelig plads, hvor den første lydgiverenhed har en første primær bevægelsesretning, som er i det væsentlige parallel med z-retningen, og den anden lydgiverenhed har en anden primær bevægelsesretning, som er i det væsentlige parallel med z-retningen, hvor den første og den anden lydgiverenhed af typen med bevægeligt armatur er modsat arrangeret i z-retningen, og hvor de U-formede armaturben af de modsat arrangerede første og anden lydgiverenheder af typen med bevægeligt armatur er rettet parallelt med x-retningen i et x,y,z-koordinatsystem.
2. Akustikenhed ifølge krav 1, hvor den anden primære retning i det væsentlige er modsat den første primære retning.
3. Akustikenhed ifølge krav 2, hvor den første og den anden lydgiverenhed er rumligt forskudt i forhold til hinanden i i det mindste x- og z-retningerne for at modvirke selvgenererede lydgivervibrationer i x- og z-retningerne og for at modvirke selvgenererede torsionsrelaterede vibrationer i y-retningen.
4. Akustikenhed ifølge krav 3, hvor den første og den anden lydgiverenhed er rumligt forskudt i x-retningen, således at der i det væsentlige ikke er noget projiceret overlap mellem den første og den anden lydgiverenhed i z-retningen.
5. Akustikenhed ifølge krav 3 eller 4, hvor den første og den anden lydgiverenhed er rumligt forskudt i z-retningen, således at der i det væsentlige ikke er noget projiceret overlap mellem den første og den anden lydgiverenhed i x-retningen.
6. Akustikenhed ifølge et hvilket som helst af de foregående krav, hvor hver af den første og den anden lydgiverenhed omfatter en lydgiver med balanceret bevægeligt armatur.
7. Akustikenhed ifølge et hvilket som helst af de foregående krav, hvor en første mikrofonenhed omfatter en første mikrofon, som har en primær vibrationssensitiv retning, og hvor en anden mikrofonenhed omfatter en anden mikrofon, som har en primær vibrationssensitiv retning.
8. Akustikenhed ifølge krav 7, hvor den første og den anden mikrofons primære vibrationssensitive retninger er i det væsentlige parallelle med y-retningen.
9. Akustikenhed ifølge krav 7, hvor den første og den anden mikrofons primære vibrationssensitive retninger er i det væsentlige vinkelret på hinanden.
10. Akustikenhed ifølge et hvilket som helst af kravene 7-9, hvor den første og den anden mikrofonenhed er mekanisk forbundet med lydgiverenhederne via en i det væsentlige ubøjelig forbindelse eller via en fleksibel forbindelse.
11. Akustikenhed ifølge et hvilket som helst af kravene 7-10, hvor den første og/eller den anden mikrofon omfatter MEMS-mikrofoner og/eller elektretmikrofoner.
12. Akustikenhed ifølge et hvilket som helst af kravene 7-11, hvilken enhed yderligere omfatter et signalbearbejdningsorgan til tilvejebringelse af retningssensitivitet fra signaler fra den første og den anden mikrofon.
13. Akustikenhed ifølge et hvilket som helst af de foregående krav, hvor den første og den anden lydgiverenhed har i det væsentlige identiske akustik- og vibrationsfrekvensrespons.
14. Akustikenhed ifølge et hvilket som helst af de foregående krav, hvilken enhed yderligere omfatter en fleksibel struktur, som enten er fastgjort til eller integreret i et hus i akustikenheden, hvor den fleksible struktur er tilpasset til at tilvejebringe en let, brugervenlig og bekvem montage af akustikenheden i en øregang.
15. Høreindretning omfattende en akustikenhed ifølge et hvilket som helst af de foregående krav, hvor høreindretningen omfatter et høreapparat, som er valgt fra den gruppe, som består af: bag øret apparat, i øret apparat, i øregangen apparat og fuldstændig i øregangen apparat.
