Abstract

The Auxgate(RTM: an ideal multimedia expansion tool for car radio) uses the interface radio output loudspeakers for simultaneous generation of improved audio sound by means of the frequency response equalizers and power amplifiers in the sound system of a motor vehicle, while maintaining mark-specific work radio.

Description

1.) Erfindungsgegenstand1.) subject of the invention

Die Erfindung betrifft eine Technik (AUXGATE) zur direkten Einspeisung und Verwaltung Externer Audio-Zuspielquellen in beliebige Kraftfahrzeug-Audioanlagen, insbesondere „ab-Werk" Soundsysteme, die von sich aus meist keine solchen Zusatzeingänge vorweisen.The The invention relates to a technique (AUXGATE) for direct injection and management of external audio sources in any automotive audio equipment, especially "ex-factory" sound systems that by itself usually have no such additional inputs.

Dies geschieht unter Nutzung der Schnittstelle Radioendstufe/Lautsprecher bei gleichzeitiger Schaffung der Möglichkeit der nachträglichen Beeinflussung (Verbesserung) des Audio-Klanges mittels z.B. Frequenzgang-Entzerrern oder Leistungsverstärker im AUXGATE.This happens by using the radio output stage / loudspeaker interface while creating the possibility of subsequent Influencing (improving) the audio sound by means of e.g. Frequency response equalizers or power amplifier in AUXGATE.

2.) Bekannte Techniken2.) Known techniques

  • 2.1) Bekannte Techniken sind Zusatzanschlüsse (Aux Inputs) an Autoradios und ähnlichen Head Units (H/U), an die man portable Musikquellen anschließen, und sie somit in das Fahrzeug-Soundsystem einspeisen kann.2.1) Known techniques are auxiliary connections (Aux Inputs) on car radios and similar Head Units (H / U) to which portable music sources are connected, and It can thus feed into the vehicle sound system.

In den meisten Fällen verfügen jedoch speziell Werksseitig integrierte Radios oder H/U (VW, Opel, Ford, etc.) nicht über diese Ausstattung und können auch nicht damit nachgerüstet werden. Somit sind dem Fahrzeugbesitzer diese Erweiterungsmöglichkeiten ohne komplizierten Eingriff in das Werks-H/U oder Austausch der Werks-H/U gegen ein entsprechend ausgestattetes Nachrüstgerät nicht zugänglich.In most cases feature however, especially factory-integrated radios or H / U (VW, Opel, Ford, etc.) do not over this equipment and can also not retrofitted with it become. Thus, the vehicle owner these expansion options without complicated intervention in the factory H / U or replacement of the Factory H / U against a suitably equipped retrofit device not accessible.

Oft wird der Austausch gegen ein Nachrüstgerät aus verschiedenen Gründen auch gar nicht gewünscht (Firmenwagen, Leasing- oder Leihfahrzeuge etc.)Often The replacement with a retrofit device for various reasons is also not at all desired (Company cars, leasing or rental vehicles, etc.)

  • 2.2) Bekannte sind ebenfalls UKW-Modulatoren, mit deren Hilfe man externe Quellen in ein vorhandenes Radio (quasi als „Sender") einspeisen kann, oder Adapter-Cassetten zur Einspeisung externer Signalquellen in ein vorhandenes Compact-Cassetten-Gerät. Diese Wege sind jedoch immer mit einer deutlichen Verschlechterung der Qualität des eingespeisten Audiosignals verbunden, da sie das Signal immer indirekt, also auf Umwegen durch das Cassetten-Abspielgerät oder den UKW Tuner einspeisen.2.2) Known are also FM modulators, with whose help one external sources in an existing radio (quasi as "transmitter"), or adapter cassettes for feeding external signal sources in an existing compact cassette player. But these ways are always with a significant deterioration in the quality of the input audio signal connected because they always the signal indirectly, so in a roundabout way the cassette player or feed the FM tuner.

3.) Einschränkungen und Probleme bekannter Techniken3.) Restrictions and problems of known techniques

Automobile neuerer Baujahre besitzen zum Größten Teil gar keine auswechselbaren Radios oder H/U mehr, sondern sind ab Werk mit integrierten Geräten ausgerüstet, deren Funktions- und Bedienelemente oft über Armaturenbrett, Instrumententräger, Mittelkonsole und Lenkrad verteilt sind, also keine zusammenhängende, DIN-Radioschacht konforme Einheit mehr bilden und sich so einem Austausch durch (DIN-Format) Nachrüstgeräte widersetzen (siehe Beispiel in 1).Automobiles of recent years are for the most part no longer interchangeable radios or H / U, but are factory-fitted with integrated devices whose functional and operating elements are often distributed over dashboard, instrument panel, center console and steering wheel, so no coherent, DIN radio shaft form a compliant unit and thus resist replacement by (DIN format) retrofit equipment (see example in 1 ).

Gleichzeitig gibt es aber einen steigenden Bedarf, externe Zuspielgeräte im Fahrzeug betreiben zu können (Stichwort „Multimedia"), um beispielsweise den Ton eines portablen Audiogerätes (z.B. iPod, MP3-Player), eines DVD-Abspielgerätes, Mobiltelefons, einer Spielekonsole, eines portablen PCs oder die Sprachausgabe eines portablen GPS-Navigationsgerätes über die Lautsprecher des Fahrzeugs wiedergeben zu können.simultaneously But there is an increasing demand, external playback devices in the vehicle to be able to operate (Keyword "Multimedia"), for example the sound of a portable audio device (for example, an iPod, MP3 player), a DVD player, a mobile phone, a game console, a portable PC or the voice output of a portable GPS navigation device over the Play the speaker of the vehicle.

Die Anwendungsbereiche der Erfindung erstrecken sich auch auf Radios und H/U, die einen solchen AUX-Input besitzen. Mittels AUXGATE können dann auch dort noch weitere Zuspielgeräte verwaltet und eingespeist werden.The Areas of application of the invention also extend to radios and H / U, which have such an AUX input. By AUXGATE can then there are also managed and fed additional source devices become.

4.) Erfindung4.) invention

Das AUXGATE löst diese Probleme auf innovative Weise:
Es stellt zusätzlich zum H/U einerseits einen bis mehrere Audio-Eingänge für Zuspielgeräte zur Verfügung und übernimmt gleichzeitig deren direkte Einspeisung ohne Umwege durch andere Komponenten in die Lautsprecher des Fahrzeug-Soundsystems, sodass die Quellen in höchster Audioqualität abgehört werden können. Hierbei nutzt er die in allen Audiosystemen vorhandene Schnittstelle Radioendstufe/Lautsprecher.
The AUXGATE solves these problems in an innovative way:
In addition to the H / U, it also provides one to several audio inputs for playback devices and at the same time feeds them directly into the loudspeakers of the vehicle sound system without detours through other components, so that the sources can be monitored in the highest audio quality. Here he uses the available in all audio systems interface radio amplifier / speakers.

5.) Funktionsbeschreibung:5.) Function description:

Die Lautsprecher werden zunächst von der H/U getrennt und das Audiosignal wird an den Lautsprecher-Ausgängen der H/U abgegriffen, auf Line-Level (0dBV) herabgesetzt. Die H/U Endstufen werden somit als Leistungsverstärker außer Kraft gesetzt und nur als Spannungsverstärker benutzt. Das so gewonnene Signal wird einem Kleinsignalmischer zugeführt. An dieser Stelle werden die externen Audioquellen zugemischt. Abschließend wird dann das so gewonnene Signal wieder einer nachfolgenden Leistungs-Audioendstufe zugeführt, die jetzt an Stelle der Radioendstufe die Lautsprecher antreibt.The Speakers are first disconnected from the H / U and the audio signal is sent to the speaker outputs of the H / U tapped, lowered to line level (0dBV). The H / U power amplifiers will be thus as a power amplifier except Power set and used only as a voltage amplifier. The won Signal is fed to a small signal mixer. At this point will be the external audio sources mixed. Finally, then the won Signal fed back to a subsequent power audio output stage, the now drives the speakers instead of the radio output stage.

Der Anschluss erfolgt am Radio sowie am originalen Fahrzeug-Kabelbaum mittels fahrzeug- oder herstellerspezifischer Adapterstecker und Kabel.Of the Connection takes place on the radio as well as on the original vehicle wiring harness by means of vehicle or manufacturer specific adapter plug and Electric wire.

Jede H/U wird auf diese Weise um die oben beschriebenen Möglichkeiten erweitert, ohne ihre Funktionalität und Integration ins Fahrzeug Interieur zu verlieren.Each H / U is extended in this way to the possibilities described above, without their functionality and integration into the vehicle interior to lose.

Der Erfindungsgegenstand AUXGATE bildet des weiteren eine Schnittstelle, um außerhalb der H/U Beeinflussungen des Audioklanges durch z.B. Equalizer, Klangregler oder Prozessoren vorzunehmen, und auf diesem Wege nochmals die Qualität der Audiowiedergabe zu verbessern.Of the Subject of the invention AUXGATE also forms an interface, around outside the H / U influences the audio sound by e.g. Equalizer, tone control or make processors, and in this way again the quality of the audio playback to improve.

Bei Verwendung einer qualitativ hochwertigen Leistungsendstufe kann zusätzlich die Klangqualität gegenüber den im H/U integrierten Verstärkerstufen gesteigert werden.at Using a high quality power amplifier can additionally the sound quality across from the amplifier stages integrated in the H / U be increased.
