Description
Den foreliggende oppfinnelse vedrører en rundstrålende høyt-talerboks med et kuleformet, todelt hus som omslutter flere høyt-talere med felles membranakse. The present invention relates to an omnidirectional loudspeaker box with a spherical, two-part housing which encloses several loudspeakers with a common membrane axis.
Fra DT-OS 1.512.747 er det kjent å anordne to høyttalere From DT-OS 1,512,747 it is known to arrange two loudspeakers
som vender mot hverandre og som har felles akse, hvorved det oppnås jevn utstråling i alle retninger vinkelrett på høyttaler-aksen. Fra US-patentskrift 3.500.953 er det kjent å anordne to høyttalere, vendende mot hverandre på en felles akse. which face each other and which have a common axis, whereby uniform radiation is achieved in all directions perpendicular to the speaker axis. From US patent 3,500,953 it is known to arrange two loudspeakers, facing each other on a common axis.
Fra DT-OS 1.512.747 er det kjent å anordne to høyttalere From DT-OS 1,512,747 it is known to arrange two loudspeakers
som vender mot hverandre og som har felles akse, hvorved det oppnås jevn utstråling i alle retninger vinkelrett på høyttaler-aksen. Den omgivende høyttalerboks har forskjellig utformete rotasjonslegemer og kan være utformet som en lampeskjerm. which face each other and which have a common axis, whereby uniform radiation is achieved in all directions perpendicular to the speaker axis. The surrounding speaker box has differently designed rotary bodies and can be designed as a lampshade.
Fra US-patentskrift 3.500.953 er det kjent et høyttaler-system med to høyttalere som vender fra hverandre og som ligger på en felles akse. Om høyttalerne er det anordnet en høyttaler-boks som kan ha forskjellig form. From US patent 3,500,953, a loudspeaker system with two loudspeakers facing away from each other and lying on a common axis is known. A speaker box is arranged around the speakers, which can have different shapes.
Formålet med den foreliggende oppfinnelse er å frembringe The purpose of the present invention is to produce
en høyttalerboks hvor det med enkel mekanisk oppbygning og enkel montering oppnås god rundstråleakustikk. a speaker box where, with a simple mechanical structure and simple assembly, good omnidirectional acoustics are achieved.
Dette er ifølge oppfinnelsen oppnådd ved at høyttalerne, According to the invention, this is achieved by the speakers,
som er beregnet for forskjellige frekvensområder, er anordnet sammen med tilhørende spredningsorganer med minimal innbyrdes - avstand ved en lydskjerm som ligger i delingsplanet for det kuleformete hus, at husets ene halvkule er utstyrt med en massiv vegg og sammen med lydskjermen danner et lukket og for bassbølgehøyttaleren lufttett rom, samt at den annen halvkule er lydgjennomtrengelig og omslutter høyttalerne om en beskyttelseshette. which are intended for different frequency ranges, are arranged together with associated scattering devices with minimal mutual - distance at a sound screen located in the dividing plane of the spherical housing, that one hemisphere of the housing is equipped with a massive wall and together with the sound screen forms a closed and for the bass wave speaker airtight room, and that the other hemisphere is sound-permeable and encloses the speakers in a protective cap.
Ved at høyttalerne, som har forskjellige frekvensområder, In that the speakers, which have different frequency ranges,
er anordnet aksialt over hverandre, bevirker de en jevn utstråling are arranged axially above each other, they cause a uniform radiation
i alle retninger vinkelrett på denne akse i høyttalerboksens høyde. Idet avstandene mellom høyttalerne er minimal, er høyt-talerboksens høyde fra membranplanet i bassbølgehøyttaleren til .enden av den øverste høyttaler av omtrent samme størrelse som membrandiameteren for bassbølgehøyttaleren, og dette bestemmer husets kuleradius^ Derved blir høyden.på den strålende lydsøyle så kort og utstrålingsplanene for de dypeste _og de høyeste toner ligger så nar hverandre at øret ikke kan oppfatte at ut-strålingen foregår fra en søyle, men oppfatter det som om den kommer fra et punkt. in all directions perpendicular to this axis at the height of the loudspeaker box. As the distances between the loudspeakers are minimal, the height of the loudspeaker box from the diaphragm plane of the woofer to the end of the top speaker is approximately the same size as the diaphragm diameter of the woofer, and this determines the spherical radius of the housing. Thereby the height of the radiant sound column is so short and the radiation planes for the deepest _and the highest tones are so close to each other that the ear cannot perceive that the radiation takes place from a column, but perceives it as if it comes from a point.
Spredningsorganene bevirker sammen med høyttalerne en prak-tisk jevn lydutstråling i hele rommet. Together with the loudspeakers, the diffusers effect a practically uniform sound emission throughout the room.
Oppfinnelsen vil bli nærmere beskrevet i det etterfølgende under henvisning til den medfølgende tegning som viser et utfør-elseseksempel. The invention will be described in more detail below with reference to the accompanying drawing showing an exemplary embodiment.
I et kuleformet hus inneholder en :halvkuleformet del, som In a spherical housing contains a :hemispherical part, which
har en massiv vegg 11, en bassbølgehøyttaler 1, mens en andre, halvkuleformet del 9 inneholder en middelbølgehøyttaler 3 og en diskantbølgehøyttaler 6.. Den halvkuleformete del med bassbølge-høyttaleren 1 avgrenses i overgangen mellom de to halvkuleformete deler av en lydskjerm 8 hvorpå bassbølgehøyttaleren er montert og derved dempes ved hjelp av et lukket hus. Den andre halvkuleformete del 9 omgir systemet av middelbølge- og diskantbølge-høyttalere 3, 6 og spredningsorganer 2, 4, 5 og er utformet lydgj ennomtrengelig. has a massive wall 11, a bass wave speaker 1, while a second, hemispherical part 9 contains a medium wave speaker 3 and a treble wave speaker 6. The hemispherical part with the bass wave speaker 1 is delimited in the transition between the two hemispherical parts by a sound screen 8 on which the bass wave speaker is mounted and thereby dampened by means of a closed housing. The second hemispherical part 9 surrounds the system of medium-wave and treble-wave loudspeakers 3, 6 and dispersion means 2, 4, 5 and is designed sound permeable.
Ved hjelp av en tilsvarende utformet monteringsanordning Using a correspondingly designed mounting device
7 kan høyttalerboksen valgfritt monteres i et stativ eller henges opp i en kjede. 7, the speaker box can optionally be mounted in a stand or suspended from a chain.
