Abstract

A car speech intercom system has microphones sited to avoid feedback connected through separate channels to headphone, car radio or seat loudspeakers for the other occupants with provision for disconnection of the speaker's loudspeaker and suppression of the radio broadcast. Includes an Independent claim for suppression of feedback using electronic circuits.

Description

Die Erfindung betrifft eine Einrichtung zur Sprachverständigung in Fahrzeugen, insbesondere in PKW. The invention relates to a device for speech communication in vehicles, especially in cars.

Mit zunehmender Geschwindigkeit eines Fahrzeuges nehmen der Motor-, Reifen- und Windgeräuschpegel ständig zu, so dass die Sprechverständigung zwischen den Fahrzeugpassagieren bei hohen Geschwindigkeiten außerordentlich erschwert ist. As the speed of a vehicle increases, the engine, tire and Wind noise levels constantly increasing, so that speech communication between the Vehicle passengers at high speeds is extremely difficult.

Eine Unterhaltung wird dann mit lauter Stimme und derart geführt, dass die Personen, die vom im Fahrzeug sitzen, den Kopf nach hinten oder zur Seite zum Gesprächspartner wenden. Das ist für die am Gespräch Beteiligten anstrengend und lenkt vom Verkehrsgeschehen derart ab, dass es zu gefährlichen Verkehrssituationen kommen kann. A conversation is then held in a loud voice and in such a way that the people who from sitting in the vehicle, head back or to the side to the conversation partner turn. This is exhausting for those involved in the conversation and distracts from Traffic events so that dangerous traffic situations can occur.

Der Erfindung lag deshalb die Aufgabe zugrunde, eine Einrichtung zu schaffen, durch die die beschriebene Situation im Fahrzeug zu vermeiden ist. The invention was therefore based on the object to provide a device through which the described situation in the vehicle must be avoided.

Die Lösung der Aufgabe erfolgt durch eine Gegensprecheinrichtung mit den Merkmalen des Anspruchs 1. Die Unteransprüche steilen zweckmäßige Ausgestaltungen der Einrichtung nach Anspruch 1 dar. The problem is solved by an intercom with the features of Claim 1. The subordinate claims steep functional configurations of the device according to claim 1.

Die Erfindung soll an einem Ausführungsbeispiel erläutert werden. The invention will be explained using an exemplary embodiment.

Im Nahbereich jedes Fahrzeugpassagiers ist ein Richtmikrofon so angeordnet, dass es von den Schallwellen der den anderen Passagieren zugeordneten Lautsprecher möglichst nicht getroffen wird. Außerdem sorgt eine ansich bekannte Elektronik für eine Unterdrückung der Rückkopplung. A directional microphone is arranged in the vicinity of each vehicle passenger so that it is from the sound waves of the loudspeakers assigned to the other passengers if possible is hit. In addition, electronics known per se suppress the Feedback.

Eine ansich bekannte elektronische Steuerung gibt das Sprachsignal auf die Übertragungskanäle der nicht sprechenden Passagiere und schließt während der Sprechdauer den Übertragungskanal des sprechenden Passagiers. A known electronic control gives the voice signal to the Transmission channels of non-speaking passengers and closes during the Talk time the transmission channel of the speaking passenger.

Zur Wiedergabe des über die Übertragungskanäle kommenden Sprechsignals können die jedem Passagier zugeordneten Lautsprecher des Autoradios oder gesondert installierte Lautsprecher verwendet werden. Bei Verwendung der Lautsprecher des Autoradios wird das Sprechsignal gegenüber dem Radiosignal bevorzugt, d. h. der Musikpegel wird während des Sprechens abgesenkt. To reproduce the speech signal coming over the transmission channels, the loudspeakers of the car radio assigned to each passenger or separately installed Speakers are used. When using the speakers of the car radio, this becomes Speech signal preferred over the radio signal, i. H. the music level is reduced during the Speaking lowered.

An Stelle der zusätzlichen Lautsprecher können für die Beifahrer auch Buchsen für den Anschluß von Kopfhörern vorgesehen sein. Instead of the additional loudspeakers, sockets for the passenger can also be used Connection of headphones may be provided.
