Anordningen om-fattar en elastisk, ringformig packning, vars insida har ett rännformigt urtag avsett att omsluta en utskjutande kant hos omvandlaren.TECHNICAL FIELD The invention relates to a device for holding, acoustically sealing and vibrating insulating an electro-acoustic converter in an apparatus housing. The device comprises an elastic, annular gasket, the inside of which has a rib-shaped recess intended to enclose a protruding edge of the transducer.
Teknikens ständpunktThe state of the art
En nögtalare eller en mikrofon fasthälls vanligen i ett apparathölje medelst fastskruvade fästdon, som är relativt utrymmeskrävande.A speaker or microphone is usually held in a device housing by means of screwed-in fasteners which are relatively space-intensive.
^5 För att ästadkomma akustisk tätning och vibrations isolering, vilket exempelvis innebär att ljudvägorna vid en högtalares baksida inte skall päverka ljudvägorna vid dess framsida, och att högtalarens vibrationer inte skall sätta apparathöljet i vibration, vilket päverkar ljudet, 2o är det förut känt att utnyttja en elastisk, ringformig packning, vars insida har ett rännformigt urtag, i vilket högtalarens kant inskjuts vid monteringen. Ett exem-pel härpä beskrivs i US 4152544, enligt vilken packnin-gen med inskjuten högtalare monteras med hjälp av hakar, 25 som mäste skruvas fast efter det att högtalaren placerats i rätt läge. Först därefter kan apparatlädan monteras i anliggning mot packningen sä att den önskade tätningen och vibrationsisoleringen erhälls.^ 5 To provide acoustic seal and vibration insulation, which means, for example, that the sound waves at the back of a speaker should not affect the sound waves at its front, and that the vibrations of the speaker should not put the device housing into vibration, which affects the sound, 2o it is known to utilize an elastic, annular gasket, the inside of which has a groove-shaped recess, into which the edge of the speaker is inserted during mounting. An example of this is described in US 4152544, according to which the package of inserted speakers is mounted by means of hooks, which must be screwed in after the speaker has been placed in the correct position. Only then can the device leather be mounted in contact with the gasket so that the desired seal and vibration insulation are obtained.
Redogörelse för uppfinningen 30 Ändamälet med föreliggande uppfinning är att till- handahälla en anordning av inledningsvis angivet slag, med vilken en elektroakustisk omvandlare kan monteras enkelt och snabbt, samtidigt som endast ett förhällandevis litet utrymme behöver tas i anspräk. Detta ästadkoms genom att 2 79229 packningens utsida försetts med en ansats, som i sam-verkan med ett antal utspräng pä insidan av en krage i apparathöljet fasthäller omvandlaren i denna.Disclosure of the Invention The object of the present invention is to provide a device of the type initially specified, with which an electroacoustic converter can be mounted easily and quickly, while only a relatively small space needs to be taken into account. This is accomplished by providing the outside of the gasket with a shoulder which in conjunction with a number of projections on the inside of a collar in the device housing holds the converter in it.

5 Figurbeskrivning5 Figure description
Uppfinningen kommer att beskrivas närmare med hän-visning till bifogad ritning, pä vilken figurerna 1 och 2 som utföringsexempel visar en högtalare med en elastisk, ringformig packning i genomskärning före respektive efter 10 montering i ett apparathölje.The invention will be described in more detail with reference to the accompanying drawing, in which Figures 1 and 2 illustrate as exemplary embodiment a speaker with an elastic, annular gasket in cross section before and after mounting in an apparatus housing.
Föredragen utföringsform I figur 1 visas en högtalare med en elastisk, ringformig packning innan dessa monterats i ett apparathölje. Högtalaren betecknas med 1 och har en utskjutande kant 2. 15 Den elastiska, ringformiga packningen 3 har ett rännfor-migt urtag 4 pä sin insida och är krängd over högtalarens kant 2 sa att denna i det närmaste är helt omsluten av packningen. Packningens i figuren övre del 5 är lämpli-gen riktad nägot utät radiellt sett, vilket gör det lät-20 tare att kränga den over kanten 2. Packningens utsida har en mot denna sida ätminstone tillnärmelsevis vinkelrät ansats 6. För att underlätta monteringen av högtalaren med sin packning i ett apparathölje, vilket sker genom att de förra trycks ned i en krage i apparathöljet, har 25 packningens utsida även ett avrundat hörn 7.Preferred Embodiment Figure 1 shows a speaker with an elastic, annular gasket before mounting it in a device housing. The speaker is denoted by 1 and has a protruding edge 2. The elastic annular gasket 3 has a gutter-shaped recess 4 on its inside and is curved over the edge of the speaker 2 so that it is almost completely enclosed by the gasket. The gasket in the upper part of the figure 5 is suitably directed somewhat outwardly radially, which makes it easier to push it over the edge 2. The outside of the gasket has an at least approximately perpendicular angle to this side 6. To facilitate the installation of the speaker with its gasket in an appliance housing, which is done by the former being pressed into a collar in the appliance housing, the outside of the gasket also has a rounded corner 7.
I figur 2 visas högtalaren och packningen efter monteringen i ett apparathölje. Höljet betecknas med 8 och har pä sin insida en krage 9, i vilken högtalaren 1 med sin packning 3 är monterade. Kragens storlek och form 30 är anpassade till högtalaren, och dess mot apparathöljets inre vettande del (uppät i figuren) är försedd med ett antal mot kragens centrum riktade, lämpligen med jämna avständ fördelade utspräng 10. Dessa har var sitt mothäll 11 i form av en mot kragens sida vinkelrät yta och var sin 35 mot kragens centrum riktad yta 12.Figure 2 shows the speaker and the gasket after assembly in a device housing. 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 30 are adapted to the loudspeaker, and its towards the inner facing part of the apparatus housing (upwards in the figure) is provided with a number of projections 10 directed towards the center of the collar. perpendicular to the side of the collar and each surface directed towards the center of the collar 12.
3 79229 Högtalaren halls fast i kragen genom att packnin-gen 3 trycks mot apparathöljet (nedät i figuren), mot kra-gens insida och mot utsprangen 10. Mothällsytorna 11 hos utsprängen anligger därvid mot ansatsen 6 sä att packnin-5 gen trycks mot apparathöljet 8, och ytorna 12 anligger mot packningens i figuren Övre, utsprungligen nägot utät riktade del 5 sä att den trycks mot den i figuren Övre sidan av högtalarens kant 2.The loudspeaker is secured to the collar by pressing the gasket 3 against the device housing (down-seated in the figure), against the collar's interior and against the projections 10. The counter-surface 11 of the projections thereby abuts the shoulder 6 so that the packaging 5 is pressed against the device housing. 8, and the surfaces 12 abut against the gasket of the gasket in the upper figure, which is originally slightly leaking, so that it is pressed against the edge of the speaker 2 in the upper side of the figure.
Vid sina mot apparathöljets inre vettande Mndar 10 har utsprangen 10 var sin sned yta 13. Dessa ytor, liksom packningens avrundade horn 7 har till uppgift att under-lätta monteringen av högtalare och packning i apparat-höljets krage.In its facing toward the inner housing of the apparatus housing 10, the projections 10 each have an oblique surface 13. These surfaces, as well as the rounded horn 7 of the gasket, are intended to facilitate the installation of speakers and gasket in the collar of the apparatus housing.
Packningens 3, kragens 9 och utsprangens 10 stor-15 lekar är anpassade sä att packningen komprimeras nägot vid monteringen. Därigenom kommer högtalaren att hällas fast i apparathöljet samtidigt som akustisk tätning och vibrationsisolering uppnäs. Med den visade anordningen fäs även en enkel montering, varvid packningen först krängs 20 over högtalarens kant, och högtalaren med päsittande packning därefter trycks ned i kragen pä apparathöljet.The sizes of the gasket 3, the collar 9 and the projections 10 are adapted so that the gasket is slightly compressed during assembly. This will allow the speaker to be pinned into the device housing while achieving acoustic seal and vibration insulation. With the device shown, a simple mounting is also fastened, the gasket first being squeezed over the edge of the speaker, and the speaker with seated gasket then pressed into the collar of the device housing.
Uppfinningen kan varieras inom ramen av patentkra-ven och exempelvis tillämpas pä mikrofoner i stället för högtalare. Givetvis kan anordningen även uppvisa detalj-25 skillnader gentemot den visade utföringsformen. Exempelvis kan ansatsen 6, mothällen 11 och övriga ytor bilda andra vinklar än de ovan visade mot anordningens övriga delar.The invention can be varied within the scope of the patent claims and, for example, applied to microphones instead of speakers. Of course, the device may also exhibit detail differences with respect to the embodiment shown. For example, the shoulder 6, the countertop 11 and the other surfaces may form angles other than those shown above against the other parts of the device.
