Description

Im Bereich des Mobilfunksektors sind bisher für den Einsatz in Fahrzeugen zahlreiche unterschiedliche Arten und Ausführungen von Freisprecheinrichtungen bekannt.So far, there are numerous in the field of the mobile radio sector for use in vehicles different types and designs of hands-free devices are known.

Auch gibt es für die Benutzung von Mobilfunktelefonen, vorzugsweise während der Bewegung, einfache Freisprecheinrichtungen. Diese bestehen aus einer Ohrhörer- und Mikrofonkombination, die am Mobilfunktelefon angeschaltet wird.There are also for the use of mobile phones, preferably during the Movement, simple hands-free devices. These consist of an earphone and Microphone combination that is activated on the mobile phone.

Allen bisher bekannten Ausführungen ist gemeinsam, dass nur eine Person das Mobil­ funktelefon benutzen kann. Eine gemeinsame Nutzung durch mehrere Teilnehmer ist nicht möglich, bedingt durch
All previously known designs have in common that only one person can use the mobile radio telephone. A shared use by several participants is not possible due to

  • - fehlende Richtcharakteristik beim Mikrofon der Freisprecheinrichtung (Umgebungsgeräusche sollen möglichst nicht übertragen werden)- No directional characteristic for the microphone of the hands-free system (Ambient noise should not be transmitted if possible)
  • - und- and
  • - zu geringe Wiedergabelautstärke des Lautsprechers.- Loudspeaker playback volume too low.

Im Geschäftsleben besteht der zunehmende Bedarf nach Telefonkonferenzen und nach einer Nutzung des Mobilfunktelefones mit Freisprecheinrichtungen, um parallel zum Telefon weitere Aktionen ausführen zu können. Auch besteht der Bedarf, die in der Box gespeicherten Nachrichten über eine Freisprecheinrichtung abhören zu können, um gleichzeitig andere Aktionen ausführen zu können.In business there is an increasing need for conference calls and for a use of the mobile phone with hands-free devices to parallel to the Phone to be able to perform further actions. There is also a need in the Box to be able to listen to stored messages via a hands-free system to be able to perform other actions at the same time.

Auf dem Markt sind auch schnurlose Telefone, die im Mobilteil (im eigentlichen Handset) eine Freisprecheinrichtung besitzen.There are also cordless telephones on the market that are in the handset (in the actual handset). have a speakerphone.

The invention has for its object to provide a mobile phone with which Hands-free calling is possible for multiple people, so conference calls are held can be.  

Technische Beschreibungtechnical description

Alle Mobilfunktelefone verfügen über eine externe Ladevorrichtung. Diese besteht im einfachsten Fall aus einem Steckernetzteil und aus einer Aufnahmeschale für das Telefon.
