Description
Oppfinnelsen angår en håndapparatkropp for telefonstasjoner, bestående av hus-overdel og hus-underdel og med telefonkapsel og mikrofonkapsel festet i hvert sitt forsenkede leie. The invention relates to a handset body for telephone stations, consisting of a housing-upper part and a housing-lower part and with a telephone capsule and a microphone capsule fixed in each a recessed bearing.
Ved håndapparater for telefonstasjoner støter man påIn the case of hand-held devices for telephone exchanges, one encounters
det problem at der på grunn av akustisk kobling mellom telefon- og mikrofonkapsel eller på grunn av støy som håndapparatkroppen overfører til telefonkapselen, blir dannet og overført utilsiktede signaler. Videre føles det generende om der på grunn av en akustisk kobling mellom telefon- og mikrofonkapsel opptrer pipetoner eller "Hall"-effekter. the problem that, due to acoustic coupling between telephone and microphone capsule or due to noise which the handset body transmits to the telephone capsule, unintended signals are formed and transmitted. Furthermore, it feels annoying if, due to an acoustic connection between the telephone and microphone capsule, beep tones or "Hall" effects occur.
For å skaffe en avkobling mot dannelsen av en lydbro mellom telefon- og mikrofonkapsel er det fra DE-PS 23 09 978 kjent å anbringe de elektroakustiske omformere i separate, elastiske og koppformede leier som i sin tur er forbundet med håndapparatkroppen. In order to provide a decoupling against the formation of a sound bridge between telephone and microphone capsule, it is known from DE-PS 23 09 978 to place the electroacoustic transducers in separate, elastic and cup-shaped bearings which in turn are connected to the handset body.
For tiden blir der i håndapparater for telefonstasjoner vesentlig benyttet piezoelektriske omformere. Disse omformere behøver hverken utskifting eller vedlikehold. Currently, piezoelectric transducers are mainly used in handsets for telephone exchanges. These converters require neither replacement nor maintenance.
Den foreliggende oppfinnelse har til oppgave å skaffeThe present invention has the task of providing
et håndapparat som avkobler lydbrodannelse mellom mikrofon-a handheld device that disconnects sound bridging between microphones
og telefonkapsel og samtidig kan produseres billig uten separate opplagringslegemer. and telephone capsule and at the same time can be produced cheaply without separate storage bodies.
Ifølge oppfinnelsen blir oppgaven løst ved at håndapparatkroppens indre rom i det minste delvis er utfylt med et akustisk dempende stoff. According to the invention, the task is solved by the inner space of the handpiece body being at least partially filled with an acoustic dampening substance.
Med hårdtskum til dette formål blir koblingen mellom telefon- og mikrofonkapsel vesentlig svekket. Den såkalte pipeavstand kan dermed bedres med faktoren 2 i forhold til den utførelse som er vist i DE-PS 23 90 978. Med hårdtskummet blir ennvidere vekten av håndapparatkroppen øket, noe som gir en sikrere betjening av telefonstasjonens ga ffelomkobler. Videre blir håndapparatets hus mer stabilt og vridningsstivt. With hard foam for this purpose, the connection between the telephone and microphone capsule is significantly weakened. The so-called spout distance can thus be improved by a factor of 2 in relation to the design shown in DE-PS 23 90 978. With the hard foam, the weight of the handset body is further increased, which provides safer operation of the telephone station's fork switches. Furthermore, the housing of the handpiece becomes more stable and torsionally rigid.
En vesentlig fordel ved avkoblingen mellom kapslene foreligger særlig ved digitale telefoner. Ved digital over-før ingsteknikk blir signalene overført praktisk talt uten dempning. En banking på håndapparatkroppen og en overledning av lyden til mikrofonkapselen ville føre til feilsignaler som på mottagningssiden i sin tur ville føre til uheldig støy med nivå i høyde med nyttesignalene. Slike telefoner ville føre til uutholdelige forstyrrelser som ikke kan aksep-teres. A significant advantage of the disconnection between the capsules exists especially with digital telephones. With digital transmission technology, the signals are transmitted practically without attenuation. A knock on the handset body and a transmission of the sound to the microphone capsule would lead to error signals which, on the receiving side, would in turn lead to undesirable noise with a level equal to the useful signals. Such telephones would cause unbearable disturbances which cannot be accepted.
I det følgende vil oppfinnelsen bli belyst nærmere ved et utførelseseksempel som på tegningen er anskueliggjort ved et snitt av håndapparatkroppen. In the following, the invention will be elucidated in more detail by means of an embodiment which is illustrated in the drawing by a section of the handpiece body.
Håndapparatkroppen er utført i to deler, en husoverdelThe handpiece body is made in two parts, a housing upper part
1 og en husunderdel 2 forbundet med denne. De to deler er sammenfestet ved hjelp av knastforbindelser som ikke er vist nærmere. I husunderdelen 2 er der utformet koppformede forsenk-ninger 3, 4 som tjener til å oppta og fiksere henholdsvis telefon- og mikrofonkapselen 5, 6. Til befestigelse av telefon-og mikrofonkapslene tjener smekkhaker 7 som er forbundet i ett stykke med husunderdelen og danner smekkforbindelse med kapslene. Kapslene er via pluggforbindelser på en til-koblingssnor 8 forbundet med telefonstasjonen, idet de elek-triske tilførselsledere er ført og fastholdt i kanaler som ikke er vist nærmere. I sammenføyet tilstand av husoverdel og -underdel blir kapslene ved hjelp av påsprøytede ribber 9 og steg 10 begrenset med hensyn til utslag i tilfelle av plutselig opptredende støtbelastninger. 1 and a housing part 2 connected to this. The two parts are joined by means of cam connections which are not shown closer. Cup-shaped recesses 3, 4 are formed in the lower part of the housing 2, which serve to receive and fix respectively the telephone and microphone capsules 5, 6. Snap hooks 7 are used to attach the telephone and microphone capsules, which are connected in one piece to the lower part of the housing and form a snap connection with the capsules. The capsules are connected to the telephone station via plug connections on a connection cord 8, the electrical supply conductors being guided and held in channels that are not shown in detail. In the joined state of the upper and lower part of the housing, the capsules are limited by means of sprayed-on ribs 9 and steps 10 with respect to deflection in the event of sudden impact loads.
For å bedre lydbro-avkoblingen mellom mikrofon- og telefonkapsel er håndapparatkroppens samlede indre rom utfylt med et hårdtskum 11. In order to improve the sound bridge decoupling between the microphone and telephone capsule, the entire internal space of the handset body is filled with a hard foam 11.
