Den foreliggende frembringelse angår et telefon-håndsæt for normaltrådet telefon (herefter benævnt telefon-håndsæt), en trådløs telefon eller en mobiltelefon af den i indledningen til krav 1 angivne art.The present invention relates to a telephone handset for a normal wired telephone (hereinafter referred to as a telephone handset), a cordless telephone or a mobile telephone of the kind specified in the preamble of claim 1.

Telefon-håndsæt, trådløse telefoner og ikke mindst mobiltelefoner er efterhånden blevet så små og kompakte, at der forekommer lydproblemer, navnlig i det lave frekvensområde, dvs. under ca. 1 kHz. Dette skyldes, at det for brugeren af små, kompakte telefoner, hvor anlægsflade eller ørestykke ofte ikke har den mest ideelle facon, kan være vanskeligt at undgå en forringet lydkvalitet, fordi basområdet er tilbøjeligt til at forsvinde, hvis ørestykket ikke holdes tæt mod øret, dvs. hvis der forekommer for store utætheder mellem øret og telefonen.Telephone handsets, cordless phones and not least mobile phones have gradually become so small and compact that sound problems occur, especially in the low frequency range, ie. below approx. 1 kHz. This is because for the user of small, compact phones, where the touchpad or earpiece often does not have the most ideal shape, it can be difficult to avoid deteriorating sound quality because the bass area tends to disappear if the earpiece is not held close to the ear, i.e. if excessive leakage occurs between the ear and the phone.

Frembringelsen har til formål at angive et telefon-håndsæt, en trådløs telefon eller en mobiltelefon, ved hvilken det ved hjælp af enkle foranstaltninger bliver muligt at kompensere for de nævnte lydproblemer i det lave frekvens-område, der skyldes de normalt forekommende utætheder mellem øret og telefonen henholdsvis telefon-håndsættet.The object of the invention is to provide a telephone handset, a cordless telephone or a mobile telephone, by which it is possible, by simple measures, to compensate for the said low-range sound problems due to the normally occurring leaks between the ear and the telephone and the telephone handset respectively.

Håndsættet, den trådløse telefon eller mobiltelefonen ifølge frembringelsen er kendetegnet ved, at der i nævnte anlægsflade eller ørestykke på en sådan måde er udformet et antal akustiske forbindelser til den indre hulhed og forekommende utætheder af håndsættet eller telefonen, at nævnte forbindelser er placeret udenfor den ringformede pakning og fortrinsvis udenfor omkredsen af transduceren men indenfor en diameter bestemt af øret repræsenteret af et standardiseret måleøre, dvs. indenfor en diameter på fortrinsvis 25 mm. Ved hjælp af enkle foranstaltninger opnås herved mulighed for at kompensere for utætheder mellem øret og telefonen henholdsvis telefon-håndsættet, således at det bliver muligt såvel i måle- og i brugssituationen at opnå en lav akustisk udgangs-impedans ved et samspil mellem en transducer med korrigeret frekvenskarakteristik og en anlægsflade eller et ørestykke med nævnte akustiske forbindelser til det indre volumen af telefon-håndsættet, den trådløse telefon eller fortrinsvis mobiltelefonen.The handset, cordless telephone or mobile telephone according to the invention is characterized in that in said contact surface or earpiece such a number of acoustic connections to the inner cavity and occurring leaks of the handset or telephone are formed, said connections are located outside the annular packing and preferably outside the perimeter of the transducer but within a diameter determined by the ear represented by a standardized measuring ear, ie. within a diameter of preferably 25 mm. By means of simple measures, it is thus possible to compensate for leaks between the ear and the phone or the telephone handset, thus enabling a low acoustic output impedance to be achieved, both by measuring a transducer with a corrected frequency characteristics and a touch surface or earpiece having said acoustic connections to the internal volume of the telephone handset, the cordless telephone or preferably the mobile telephone.

2 DK 98 00008 U32 DK 98 00008 U3

Det skal påpeges, at den aktuelle facon af nævnte forbindelser, huller eller åbninger i anlægsfladen eller ørestykket ind til det indre hulrum af håndsættet, den trådløse telefon eller mobiltelefonen kan vælges helt vilkårligt. Det skal ligeledes nævnes, at der i forbindelse med fremtidige typegodkendelser af mobiltelefoner som et krav kan måles med et nyt type 3.2 måleøre i stedet for det nugældende type IEC 318 måleøre. For begge måleører gælder imidlertid, at der anvendes koblingsstykker med en diameter på 25 mm til at danne forbindelse til ørestykket.It should be pointed out that the current shape of said connections, holes or openings in the contact surface or earpiece into the interior cavity of the handset, cordless telephone or mobile phone can be selected at random. It should also be mentioned that in connection with future type approvals of mobile phones as a requirement can be measured with a new type 3.2 measuring ears instead of the current type IEC 318 measuring ears. However, for both measuring ears, 25 mm diameter coupling pieces are used to connect to the earpiece.

I den periode, hvor begge typer måleører i princippet kan forlanges anvendt ved typegodkendelse af et givet telefon-håndsæt, en given trådløs telefon eller en given mobiltelefon, kan det komme på tale at anvende to forskellige varianter af transducere og to forskellige design af ørestykker - men naturligvis med samme principielle opbygning.In the period when both types of measuring ears can in principle be required to be used for the type-approval of a given telephone handset, a given wireless telephone or a given mobile phone, it may be necessary to use two different variants of transducers and two different earpiece designs - but of course with the same principled structure.

Hensigtsmæssigt er håndsættet, den trådløse telefon eller mobiltelefonen ifølge frembringelsen udformet således, at nævnte akustiske forbindelser i anlægsfladen eller ørestykket udgøres af cirkulære åbninger, der er lette at fremstille og fordele indenfor måleøre-omkredsen.Conveniently, the handset, cordless telephone or mobile telephone according to the invention is designed such that said acoustic connections in the abutment or earpiece are circular openings which are easy to manufacture and distribute within the measuring ear circumference.

Eller håndsættet, den trådløse telefon eller mobiltelefonen ifølge frembringelsen kan på fordelagtig måde modificeres ved, at nævnte akustiske forbindelser i anlægsfladen eller ørestykket udgøres af smalle retlinede og/eller buede slidser, der kan udgøre kendetegn for given fabrikant.Or, the handset, cordless telephone or mobile telephone according to the invention may advantageously be modified in that said acoustic connections in the abutment or earpiece are constituted by narrow rectilinear and / or curved slits which may be characteristics of a given manufacturer.

Fortrinsvis er telefon-håndsættet, den trådløse telefon eller mobiltelefonen ifølge frembringelsen yderligere således modificeret, at nævnte akustiske forbindelser er udformet resistive fortrinsvis ved påsætning af netvæv fortrinsvis på nævnte indervæg af anlægsfladen eller ørestykket. På særlig enkel måde opnås herved en rent resistiv akustisk forbindelse mellem ørestykket og det indre hulrum af telefon-håndsættet, den trådløse telefon eller mobiltelefonen - med det formål at opnå en mere optimal frekvenskarakteristik.Preferably, the telephone handset, cordless telephone or mobile telephone according to the invention is further modified such that said acoustic connections are formed resistive preferably by attaching mesh tissue preferably to said inner wall of the abutment surface or earpiece. In a particularly simple manner, a purely resistive acoustic connection is obtained between the earpiece and the inner cavity of the telephone handset, the cordless telephone or the mobile phone - for the purpose of obtaining a more optimal frequency characteristic.

3 DK 98 00008 U33 DK 98 00008 U3

Med særlig fordel kan telefon-håndsættet, den trådløse telefon eller mobiltelefonen ifølge frembringelsen desuden modificeres ved, at nævnte akustiske forbindelser og/eller lydåbninger i anlægsfladen eller ørestykket er udformet i facon eller mønster sammen med fordybninger på en sådan måde, at forbindelser, åbninger og fordybninger fortrinsvis som en helhed danner firma-kendetegn (logo) for fabrikanter af telefon-hånds æt, trådløse telefoner eller mobiltelefoner.In particular, the telephone handset, cordless telephone or mobile telephone according to the invention can further be modified in that said acoustic connections and / or sound openings in the contact surface or earpiece are formed in shape or pattern together with depressions in such a way that connections, openings and recesses, preferably as a whole, form company characteristics (logo) for manufacturers of telephone handsets, cordless phones or mobile phones.

Alternativt kan telefon-håndsættet, den trådløse telefon eller mobiltelefonen ifølge frembringelsen være af den type, hvor anlægsfladen eller ørestykket er placeret på indvendig side af en svingbar klap, der fra en indsvunget inaktiv position, hvor klappen eksempelvis dækker tastatur og display, er indrettet til at udsvinges til en aktiv position, hvor anlægsfladen eller ørestykket kan presses imod et øre, og være kendetegnet ved, at transduceren er indbygget i klappen på en sådan måde, at bagsiden af transduceren har en eller flere akustiske forbindelser ud igennem bagsiden af klappen.Alternatively, the telephone handset, cordless telephone or mobile telephone according to the invention may be of the type in which the contact surface or earpiece is located on the inside of a pivotable flap which, from a pivoted inactive position, where the flap, for example, covers the keyboard and display, is adapted for use. being swung to an active position where the abutment or earpiece can be pressed against an ear, and characterized in that the transducer is built into the flap in such a way that the back of the transducer has one or more acoustic connections through the back of the flap.

Ved denne alternative udførelsesform kan det være særligt hensigtsmæssigt, at transduceren er indbygget i klappen på en sådan måde, at der i anlægsfladen eller ørestykket udenfor transduceren men indenfor nævnte diameter repræsenteret af nævnte standardiserede måleøre er udformet en passage gennem klappen ud til det fri.In this alternative embodiment, it may be particularly convenient for the transducer to be built into the flap in such a way that a passage through the flap outwardly is formed in the abutment or earpiece outside the transducer but within said diameter represented by said standard measuring ears.

Frembringelsen forklares i det følgende nærmere i forbindelse med tegningen, på hvilken:-The invention is explained in the following in connection with the drawing, in which: -

Fig. 1 viser et sidebillede - delvis i snit - af en udførelsesform for en trådløs telefon eller en mobiltelefon ifølge frembringelsen med et ørestykke og en transducer, fig. 2 viser et plant delbillede af en udførelsesform for en mobiltelefon ifølge frembringelsen - set fra ydersiden deraf, 4 DK 98 00008 U3 fig. 3 viser et tilsvarende delbillede af en den i fig. 2 viste mobiltelefon - set fra bagsiden deraf, medens fig. 4 viser et delbillede - delvis i snit - af en modificeret udførelsesform for en mobiltelefon med klap ifølge frembringelsen.FIG. 1 shows a side view - partly in section - of an embodiment of a cordless telephone or a mobile telephone according to the invention with an earpiece and a transducer; FIG. 2 shows a planar sectional view of an embodiment of a mobile telephone according to the invention - seen from the outside thereof, FIG. 3 shows a similar partial view of the one shown in FIG. 2 from the back thereof, while FIG. 4 shows a partial view - partly in section - of a modified embodiment of a flap mobile phone according to the invention.

I fig. 1 er vist, hvordan en transducer 2 er indbygget i en mobiltelefon 4 på en sådan måde, at bagsiden af transduceren 2 vender mod og udnytter det indre volumen 6 samt forekommende utætheder af mobiltelefonen 4. Transduceren 2 er langs en ringformet forsidedel fastgjort til en indervæg 8 af et ørestykke 10 ved hjælp af en ringformet pakning eller en ring 12 af dobbeltklæbende tape.In FIG. 1, it is shown how a transducer 2 is built into a mobile phone 4 in such a way that the back of the transducer 2 faces and utilizes the internal volume 6 as well as existing leaks of the mobile phone 4. The transducer 2 is attached to an inner wall along an annular front part. 8 of an earpiece 10 by means of an annular gasket or a ring 12 of double-sided tape.

Ud for den centrale del af forsiden af transduceren 2 er ørestykket udformet med et antal lydhuller 14 og et forbindelseshul 16, der er placeret indenfor en diameter svarende til diameteren af et punkteret koblingsstykke 18 til et måleøre.Off the central portion of the front of transducer 2, the earpiece is formed with a plurality of sound holes 14 and a connecting hole 16 located within a diameter corresponding to the diameter of a punctured coupling piece 18 to a measuring ear.

Fig. 2 og 3 viser en øverste del af et forstykke af en mobiltelefon 4 med et ørestykke 10, i hvis yderside er udformet tre rette recesser eller fordybninger 22, 23 og 24. I den ene ende af den øverste fordybning 22 er udformet en aflang lydåbning 14, medens der i modsatte ende af alle tre fordybninger 22, 23 og 24 er udformet aflange forbindelsesåbninger 16 til det indre volumen 6 af mobiltelefonen 4, der også omfatter et display 26.FIG. 2 and 3 show an upper part of a front of a mobile phone 4 with an earpiece 10, the outer side of which is formed three straight recesses or recesses 22, 23 and 24. At one end of the upper recess 22 is an elongated sound opening 14 while at opposite ends of all three recesses 22, 23 and 24 elongate connecting openings 16 are provided for the inner volume 6 of the mobile phone 4, which also includes a display 26.

Som vist i fig. 2 er lydåbningen 14 og forbindelsesåbningeme 16 placeret indenfor måleøre-diameteren 18 - ligesom det tydeligt ses, at forbindelsesåbningeme 16 til det indre volumen 6 af mobiltelefonen 4 er placeret udenfor transduceren 2 men indenfor måleøre-diameteren 18. Indersiden af forbindelsesåbningeme 16 er - som vist i fig. 3 -dækket ved hjælp af et finmasket netvæv 20, således at forbindelserne til det indre volumen 6 af mobiltelefonen 2 akustisk bliver rent resistive forbindelser.As shown in FIG. 2, the sound opening 14 and the connection openings 16 are located within the measuring ear diameter 18 - as can be clearly seen that the connection openings 16 for the internal volume 6 of the mobile phone 4 are located outside the transducer 2 but within the measuring ear diameter 18. The inside of the connection openings 16 are - as shown. in FIG. 3 covered by a fine mesh web 20 so that the connections to the inner volume 6 of the mobile phone 2 become acoustically pure resistive connections.

Fig. 4 viser en modificeret udførelsesform for en mobiltelefon ifølge frembringelsen, nemlig en mobiltelefon af den meget kompakte type med en klap 28, der er indrettet til 5 DK 98 00008 U3 # at udsvinges fra en inaktiv stilling, hvori klappen 28 eksempelvis dækker tastatur og display, til en aktiv brugstilling, hvor klappen 28 eksempelvis indtager en stump vinkel i forhold til mobiltelefonens basisdel, idet telefones højttaler (transducer 2) er monteret i klappen 28 på en sådan måde, at anlægsfladen eller ørestykket 10 findes på indvendig side af klappen 28, dvs. at telefonens mikrofon er placeret på basisdelen eksempelvis ved undersiden af tastaturet. Ud for anlægsfladen eller ørestykket 10 har klappen 28 en tykkelse, der kun netop giver plads til transduceren 2. Udvendig side af klappen 28 er ud for bagsiden af transduceren 2 udformet med et antal huller 30 til det fri. Umiddelbart -udenfor omkredsen af transduceren 2 men indenfor måle-ørediameteren 18 er klappen 28 udformet med en passage 32, således at forsiden af transduceren 2 derved også er forbundet til det fri, når ørestykket 10 presses mod et øre.FIG. 4 shows a modified embodiment of a mobile telephone according to the invention, namely a mobile phone of the very compact type with a flap 28 arranged to be swung from an inactive position, in which the flap 28 covers, for example, the keyboard and display, for an active use position, where the flap 28, for example, takes a blunt angle with respect to the base of the mobile phone, the telephone speaker (transducer 2) mounted in the flap 28 in such a way that the contact surface or earpiece 10 is located on the inside of the flap 28, i.e. . that the phone's microphone is located on the base part, for example at the bottom of the keypad. Beside the abutment surface or the earpiece 10, the flap 28 has a thickness that only allows space for the transducer 2. Exterior side of the flap 28 is formed outside the back of the transducer 2 with a number of holes 30 open. Immediately outside the perimeter of the transducer 2 but within the measuring ear diameter 18, the flap 28 is formed with a passage 32 such that the front of the transducer 2 is thereby also connected to the outside as the ear piece 10 is pressed against an ear.

Med andre ord er det frembringelsens hovedaspekt at tilsikre en forbedret lydkvalitet i det lave frekvensområde, dvs. under ca. 1 kHz, selv om der anvendes normale transducerkapsler såvel som små kompakte transducer-kapsler, hvilket opnås ved at forbinde ørestykket og i princippet øret repræsenteret af måleøret med det indre volumen af tele-fon-håndsættet, den trådløse telefon eller mobiltelefonen.In other words, it is the main aspect of production to ensure an improved sound quality in the low frequency range, ie. below approx. 1 kHz, although normal transducer capsules as well as small compact transducer capsules are used, which is achieved by connecting the earpiece and, in principle, the ear represented by the measuring ear with the internal volume of the telephone handset, cordless telephone or mobile phone.
