Abstract

A mobile communications terminal is provided having a first loudspeaker for emitting sound signals in a normal mode of the communications terminal, a second loudspeaker for emitting sound signals in a hands-free mode of the communications terminal, an antenna and a signal processing device for processing signals which have been received by the antenna and for supplying processed signals to the first loudspeaker and to the second loudspeaker depending on whether the communications terminal is in the normal mode or in the hands-free mode, wherein better high-frequency reproduction in a hands-free mode is achieved in that, in the hands-free mode, the signal processing device is designed to supply processed signals at a frequency of more than 1 kHz to the first loudspeaker and the first loudspeaker is designed to reproduce sound signals at a frequency of more than 1 kHz.
