Abstract

En høyttaler omfattende et hus utstyrt med en magnetenhet som genererer et magnetfelt og en membran som er montert i en ramme som er utstyrt med en elektrisk leder arrangert i et mønster på membranen, hvor membranen er plassert i magnetfeltet på en slik måte at en kraft utøves når sfrøm blir matet gjennom ledermønsteret på membranen, hvor kraften er i stand til å sette membranen i bevegelse for å frembringe lyd, hvor ledermønsteret er plassert på membranen i minst to atskilte vibrasjonsområder, hvor høyttaleren er utstyrt med minst to lydkanaler som sttekker seg meUom de to vibrasjonsområder og yttersiden av huset, og hvor den senttale akse av de to lydkanaler, som er plassert meUom ytterveggen og innerveggen av hver kanal, heller mot hverandre over en bestemt avstand fra membranen.
