Abstract
(EN)
The invention relates to controlling the equalizer in a mobile communication terminal, advantageously a mobile phone. According to the invention, the communication terminal comprises means for decreasing the frequency selective attenuation by the equalizer when a maximum amplification by the amplifier has already been reached in order to increase the volume of the sound reproduced by the loudspeaker.
(FR)
Cette invention se rapporte au réglage de l'égaliseur dans un terminal de communication mobile, un téléphone mobile pour plus d'efficacité. Selon l'invention, le terminal de communication comprend un moyen qui met en oeuvre l'égaliseur pour diminuer l'évanouissement progressif de fréquences lorsqu'une amplification maximale réalisée par l'amplificateur est déjà atteinte, afin d'augmenter le volume du son reproduit par le haut-parleur.
