Abstract

The invention concerns a mobile terminal with at least two transducers (LSm, LSs, LSS) used simultaneously as loudspeakers for stereophonic effect. According to the invention, one of said transducers is a main transducer (LSm) with a main working frequency band (Bm) corresponding to at least the phone frequency band, while the other transducer is a secondary transducer (LSs; LSs) with a secondary working frequency band (Bs; Bs) band different from said main frequency band, the lowest frequencies of said secondary working frequency band (Bs; Bs) being greater than the lowest frequencies of said main working frequency band.
