Abstract

Es wird ein Verfahren zur Eingabe von akustischen Signalen in ein elektrisches Gerät (1) und ein elektrisches Gerät (1) vorgeschlagen, bei dem kein Mikrofon erforderlich ist. It is proposed a method for inputting acoustic signals into an electrical device (1) and an electrical device (1) in which no microphone is required. Dabei wird einem dem Gerät (1) zugeordneten Lautsprecher (5) ein akustisches Signal, insbesondere ein Sprachsignal, zugeführt. In this case, a device (1) associated with the speaker (5), an acoustic signal, in particular a speech signal, respectively. Das akustische Signal wird vom Lautsprecher (5) in ein elektrisches Signal umgewandelt und einem Signalausgang (10) des Lautsprechers (5) zugeführt. The acoustic signal is converted by the loudspeaker (5) into an electrical signal and a signal output (10) of the loudspeaker (5), respectively. Ein Verknüpfungssignal wird durch Vergleich eines Ausgangssignals des Lautsprechers (5) mit einem Bewertungssignal gebildet. A combination signal is formed by comparing an output signal of the loudspeaker (5) with an evaluation signal. Das Bewertungssginal wird aus einem Eingangssignal an einem Signaleingang (15) des Lautsprechers (5) in Abhängigkeit einer Übertragungsfunktion zwischen dem Signaleingang (15) und dem Signalausgang (10) des Lautsprechers (5) so abgeleitet, daß der Einfluß des Eingangssignals auf das Verknüpfungssignal reduziert wird. The Bewertungssginal is derived from an input signal at a signal input (15) of the loudspeaker (5) as a function of a transfer function between the signal input (15) and the signal output (10) of the speaker (5) so that the influence of the input signal is reduced to the link signal becomes.
