Abstract:
A mobile radio terminal comprising an audio transducer providing earpiece and loudspeaker functions and an outlet that is oriented towards the front face of the terminal, wherein:the audio transducer provides a ringer function; and the terminal further comprises, coupled to the transducer, means for adjusting the level of the sound wave emitted by the transducer in a main direction substantially perpendicular to the front face, wherein the sound wave level is adjusted regardless of the position of the terminal relative to a user and the sound wave level is sufficient for distant use of the terminal and is less than a predetermined value for close use, the adjustment means comprising a guide member for the sound wave comprising a guide wall in which at least one guide hole is formed, the guide member being coupled to the front face of the terminal so that the guide hole faces the outlet of the transducer to limit the level of the sound wave emitted in the main direction, and the guide wall and the front face of the terminal provide a diversion channel for at least part of the sound wave in a secondary direction different to the main direction.
