Description

TEKNISK OMRÅDE TECHNICAL AREA

Foreliggende oppfinnelse vedrører en anordning for fastholdelse, akustisk tetning og vibrasjonsisolering av en elckt.ro-akustisk omformer i et apparathus. Anordningen omfatter en elastisk, ringformet pakning, hvis innside har en renneformet uttagning beregnet på å omslutte en utadragende kant. på omformeren. The present invention relates to a device for retaining, acoustic sealing and vibration isolation of an elckt.ro acoustic converter in an apparatus housing. The device comprises an elastic, ring-shaped gasket, the inside of which has a channel-shaped recess designed to enclose a protruding edge. on the inverter.

TEKNIKKENS STAND STATE OF THE ART

En høyttaler eller en mikrofon fastholdes vanligvis i et apparathus ved hjelp av fastskrudde festeorganer, som er rela-tivt plasskrevende. /A loudspeaker or a microphone is usually held in an apparatus housing by means of screwed fastening means, which are relatively space-consuming. /

For å tilveiebringe akustisk tetning og vibrasjonsisolering, hvilket f.eks. innebærer at lydbølgene ved en høyttalers bak-side ikke skal påvirke lydbølgene ved dens forside, og at høyttalerens vibrasjoner ikke skal sette apparathuset i vi-brasjon, hvilket påvirker lyden, er det tidligere kjent å anvende en elastisk, ringformet pakning, hvis innside har en renneformet uttagning, i hvilken høyttalerens kant skyves inn ved monteringen. Et eksempel på dette er beskrevet i US 4 152 544, ifølge hvilket pakningen med innskjøvet høyttaler monteres ved hjelp av kroker, som må skrus fast etter at høyt-taleren er plassert i riktig stilling. Først etter at dette er gjort kan apparathuset monteres i anlegg med pakningen, slik at den ønskede tetning og vibrasjonsisolering oppnås. To provide acoustic sealing and vibration isolation, which e.g. means that the sound waves at the rear of a speaker should not affect the sound waves at its front, and that the speaker's vibrations should not set the apparatus housing into vibration, which affects the sound, it is previously known to use an elastic, ring-shaped seal, the inside of which has a channel-shaped recess, into which the speaker's edge is pushed during installation. An example of this is described in US 4 152 544, according to which the gasket with a pushed-in speaker is mounted by means of hooks, which must be screwed in after the loudspeaker has been placed in the correct position. Only after this has been done can the device housing be mounted in contact with the gasket, so that the desired seal and vibration isolation is achieved.

REDEGJØRELSE FOR OPPFINNELSEN ACCOUNT OF THE INVENTION

Formålet med foreliggende oppfinnelse er å tilveiebringe en anordning av den i innledningen nevnte type, med hvilken en elektroakustisk omformer kan monteres enkelt, og raskt, samtidig som kun forholdsvis liten plass behøver å beslaglegges. Dette oppnås ved at pakningens utside er forsynt med en ansats, som i samvirke med et antall fremspring på innsiden av en krave i apparathuset fastholder omformeren i denne. The purpose of the present invention is to provide a device of the type mentioned in the introduction, with which an electroacoustic converter can be mounted simply and quickly, while only a relatively small space needs to be taken up. This is achieved by the outside of the gasket being provided with a shoulder, which in cooperation with a number of protrusions on the inside of a collar in the device housing holds the converter in it.

Anordningens karakteristiske trekk fremgår av patentkravene. The device's characteristic features appear from the patent claims.

FlGURBESKRIVELSE FlGUR DESCRIPTION

Oppfinnelsen vil bli beskrevet nærmere under henvisning til den vedføyede tegning, på hvilken fig. 1 og 2 som utførelses-eksempel viser en høyttaler med en elastisk, ringformet pakning i tverrsnitt før respektive etter montering i et apparathus. The invention will be described in more detail with reference to the attached drawing, in which fig. 1 and 2 as an embodiment show a speaker with an elastic, ring-shaped seal in cross-section before and after installation in an apparatus housing, respectively.

FORETRUKKET UTFØRELSESFORM PREFERRED EMBODIMENT

På fig. 1 vises en høyttaler med en elastisk, ringformet pakning før den monteres i et apparathus. Høyttaleren betegnes med 1 og har en utadragende kant 2. Den elastiske, ringformede pakning 3 har en renneformet uttagning 4 på sin innside og er presset over høyttalerens kant 2, slik at denne er prak-tisk talt helt omsluttet av pakningen. Pakningens øvre del 5 på figuren er fortrinnsvis rettet noe utad radielt sett, hvilket gjør det lettere å presse den over kanten 2. Pakningens utside har en ansats 6 som er tilnærmelsesvis vinkelrett på denne side. For å lette monteringen av høyttaleren med sin pakning i et apparathus, hvilket skjer ved at disse trykkes ned i en krave i apparathuset, har pakningens utside også et avrundet hjørne 7. In fig. 1 shows a speaker with an elastic, ring-shaped gasket before it is mounted in an apparatus housing. The loudspeaker is denoted by 1 and has a protruding edge 2. The elastic, ring-shaped gasket 3 has a channel-shaped recess 4 on its inside and is pressed over the speaker's edge 2, so that it is practically completely enclosed by the gasket. The gasket's upper part 5 in the figure is preferably directed slightly outwards radially, which makes it easier to press it over the edge 2. The gasket's outside has a shoulder 6 which is approximately perpendicular to this side. In order to facilitate the installation of the loudspeaker with its gasket in an appliance housing, which is done by pressing these down into a collar in the appliance housing, the outside of the gasket also has a rounded corner 7.

På fig. 2 vises høyttaleren og pakningen etter monteringen i In fig. 2 shows the speaker and the gasket after installation i

et apparathus. Huset betegnes med 8 og har på sin innside en krave 9, i hvilken høyttaleren 1 med sin pakning 3 er mon-tert. Kravens størrelse og form er tilpasset høyttaleren, an apparatus house. The housing is denoted by 8 and has on its inside a collar 9, in which the speaker 1 with its gasket 3 is mounted. The size and shape of the collar is adapted to the speaker,

og dens del som vender mot apparathusets indre (oppad på figuren) er forsynt med et antall fremspring 10 som fortrinnsvis er jevnt fordelt og rettet mot kravens sentrum. Hvert av fremspringene har et mothcld 11 i form av en på kravens side vinkelrett flate og også en flate 12 rettet mot kravens sentrum. and its part which faces the interior of the apparatus housing (upwards in the figure) is provided with a number of projections 10 which are preferably evenly distributed and directed towards the center of the collar. Each of the projections has a counter part 11 in the form of a perpendicular surface on the side of the collar and also a surface 12 directed towards the center of the collar.

Høyttaleren holdes fast i kraven ved at pakningen 3 trykkes mot apparathuset (nedad på figuren), mot kravens innside og mot fremspringene 10. Fremspringenes motholdsflater 11 ligger da an mot ansatsen 6, slik at pakningen trykkes mot apparathuset 8, og flatene 12 ligger an mot pakningens på figuren øvre del 5 som opprinnelig var noe utadrettet, slik at den trykkes mot den på figuren øvre side av høyttalerens kant 2. The loudspeaker is held firmly in the collar by pressing the gasket 3 against the device housing (downwards in the figure), against the inside of the collar and against the projections 10. The counter-holding surfaces 11 of the projections then rest against the shoulder 6, so that the gasket is pressed against the apparatus housing 8, and the surfaces 12 rest against the upper part of the gasket in the figure 5, which was originally slightly outwards, so that it is pressed against the upper part of the figure by the speaker's edge 2.

Hvert av fremspringene 10 har en skrå flate 13 ved sine ender som vender mot apparathusets indre. Disse flater, likesom pakningens avrundede hjørne 7 har til oppgave å lette monteringen av høyttaler og pakning i apparathusets krave. Each of the projections 10 has an inclined surface 13 at its ends which faces the interior of the apparatus housing. These surfaces, like the gasket's rounded corner 7, have the task of facilitating the installation of the speaker and gasket in the device housing's collar.

Størrelsen av pakningen 3, kraven 9 og fremspringene 10 er tilpasset slik at pakningen er noe komprimert ved monteringen. Derved vil høyttaleren fastholdes i apparathuset samtidig som akustisk tetning og vibrasjonsisolering oppnås. Med den viste anordning fås også en enkel montering, idet pakningen først presses over høyttalerens kant, og høyttaleren med på-sittende pakning deretter trykkes ned i kraven på apparathuset . The size of the gasket 3, the collar 9 and the protrusions 10 are adapted so that the gasket is somewhat compressed during assembly. Thereby, the loudspeaker will be retained in the device housing while acoustic sealing and vibration isolation are achieved. With the device shown, a simple installation is also achieved, as the gasket is first pressed over the speaker's edge, and the speaker with the gasket in place is then pressed down into the collar of the device housing.

Oppfinnelsen kan varieres innenfor rammen av patentkravene The invention can be varied within the scope of the patent claims

og eksempelvis anvendes for mikrofoner istedenfor høyttalere. Anordningen kan selvsagt også ha detalj forskjeller med hen-syn til den viste utførelsesform. F.eks. kan ansatsen 6, motholdene 11 og øvrige flater danne andre vinkler enn de viste med anordningens øvrige deler. and, for example, is used for microphones instead of speakers. The device can of course also have differences in detail with respect to the embodiment shown. E.g. can the abutment 6, the counter-holds 11 and other surfaces form other angles than those shown with the other parts of the device.
