Claims (14)

1. Bluetooth-mikrofon (10) omfattende: en transducer (1), der er indrettet til at tilvejebringe en elektronisk repræsentation af et akustisk signal; en analog-til-digital-konverter (16) til konvertering af den elektroniske repræsentation til et digitalt signal; et codec (18) til generering af en sekvens af pakker baseret på det digitale signal; en afkoder (20) til konvertering af en modtaget sekvens af pakker til et digitalt stereosignal; en digital-til-analog-konverter (22) til konvertering af det digitale stereosignal til et analogt stereosignal, der er egnet til transmission til et sæt hovedtelefoner; og en styreenhed (MCU) og en Bluetooth-transceiver (12), der er indrettet til: at etablere en parret Bluetooth-forbindelse med en indretning; at etablere en A2DP, Advanced Audio Distribution Profile, -forbindelse med den parrede indretning til modtagelse af sekvensen af pakker til afkoderen (20) fra indretningen; og at etablere en SPP, Serial Port Profile, -forbindelse med den parrede enhed til samtidig transmittering af den genererede sekvens af pakker baseret på det digitale signal til den parrede indretning, mens den modtagne sekvens af pakker afkodes til transmission til sættet af hovedtelefoner.
2. Bluetooth-mikrofon ifølge krav 1, yderligere omfattende en aktuator til signalering til den parrede indretning, at mikrofonen er klar til etablering af hver af A2DP- og SPP-forbindelserne.
3. Bluetooth-mikrofon ifølge krav 1, yderligere omfattende en volumen-styre-enhed til angivelse af en ønsket volumen for optagelse af det akustiske signal.
4. Bluetooth-mikrofon ifølge krav 1, yderligere omfattende et hovedtelefonstik til modtagelse og en hovedtelefon-jack og til transmittering af det analoge stereosignal til hovedtelefonerne.
5. Bluetooth mikrofon ifølge krav 1, yderligere omfattende et USB-stik til modtagelse af en USB-ledning, hvilket stik er operativt forbundet med et genopladeligt batteri til ladning af Bluetooth-mikrofonen.
6. Bluetooth-mikrofon ifølge krav 1, hvor A/D-konverteren er indrettet til at sample det akustiske signal ved mellem 8 kHz-192 kHz.
7. Bluetooth-mikrofon ifølge krav 1, hvor analog-til-digital-konverteren er indrettet til at tilvejebringe en digital repræsentation med en opløsning på mellem 8 bit til 32 bit af det akustiske signal
8. Bluetooth-mikrofon ifølge krav 1, hvor codec'et er indrettet til at kode det digitale signal i en af: AAC-, MP3-, WMA- eller aptX-format.
9. Bluetooth-mikrofon ifølge krav 1, hvor styreenheden indbefatter en buffer, og hvor sekvensen af pakker baseret på det digitale signal transmitteres til den parrede enhed gennem bufferen, når kommunikation er tilgængelig med den parrede indretning.
10. System omfattende en Bluetooth-mikrofon ifølge krav 1 og computerekse-kverbar kode, som, når den eksekveres på en Bluetooth-indretning, er indrettet til: at etablere en parret forbindelse med Bluetooth-mikrofonen; at etablere en A2DP (Advanced Audio Distribution Profile)-forbindelse med Bluetooth-mikrofonen til transmission af sekvensen af pakker til afkoderen til Bluetooth-mikrofonen; og at etablere en SPP (Serial Port Profile)-forbindelse med Bluetooth-mikrofonen til samtidigt at modtage sekvensen af pakker fra Bluetooth-mikrofonen, mens sekvensen af pakker transmitteres til Bluetooth-mikrofonen.
11. System ifølge krav 10, hvor computerprogramkoden er indrettet til at tilvejebringe en brugergrænseflade, der gør det muligt for en bruger at vælge en audiofil, der skal streames til Bluetooth-mikrofonen gennem A2DP-forbindel-sen.
12. System ifølge krav 11, hvor computerprogramkoden er indrettet til at tilvejebringe en brugergrænseflade, der gør det muligt for en bruger at initiere hver af A2DP- og SPP-forbindelserne, at påbegynde streaming af en valgt audiofil og at påbegynde modtagelse af sekvensen af pakker fra Bluetooth-mikrofo-nen.
13. System ifølge krav 11, hvor computerprogramkoden er indrettet til at lagre den modtagne sekvens af pakker som en audiofil.
14. Bluetooth-mikrofon ifølge krav 5, hvori USB-stik-mikrofonstifterne er forbundet med styreenheden, og hvor styreenheden reagerer på detektering af, at der tilvejebringes effekt til mikrofonen gennem USB-stikket, til tilvejebringelse af en elektronisk repræsentation af det akustiske signal til USB-stik-mi-krofon stifterne.
