Abstract
The invention concerns a mobile terminal with at least two transducers (LSm, LSs1, LSS2) 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 (LSs1; LSs2) with a secondary working frequency band (Bs1; Bs2) band different from said main frequency band, the lowest frequencies of said secondary working frequency band (Bs1; Bs2) being greater than the lowest frequencies of said main working frequency band.

1-10. (canceled)
A wireless transmit/receive unit (WTRU), comprising:
- a first surface extending in at least longitudinal and width directions, the first surface defining a first opening;
- a housing extending in the longitudinal direction, extending in the width direction, and extending in a depth direction, the housing having:
- (1) a second surface extending in at least the width and depth directions, the second surface defining a second opening;
- a first transducer configured to:
- (1) produce first sound from a first audio signal, and (2) direct the first sound in a first direction through the first opening defined by the first surface;
- and
- a second transducer configured to:
- (1) produce second sound from a second audio signal, and (2) direct the second sound in a second direction through the second opening in the housing;
- wherein:
- the first surface and the housing are configured to be coupled together,
- the first transducer and the second transducer are configured to produce stereophonic sound,
- the first opening is centered in the first surface with respect to the width direction, and
- the second opening is offset from a center of the housing with respect to the width direction.
