Title (EN) MULTI-MODE AUDIO PROCESSORS AND METHODS OF OPERATING THE SAME
(FR) PROCESSEURS AUDIO MULTIMODAUX ET PROCEDES DE FONCTIONNEMENT
Abstract:
(EN) A portable electronic device is provided that includes a housing and first and second spaced apart transducers positioned in the housing. A multi-mode audio processor circuit is configured to transmit sound from the first transducer in a first mode of operation and to generate a composite audio signal from sound energy received by the first and second transducers in a second mode of operation. Related mobile terminals and methods of operating portable electronic devices are also provided.
(FR) Un dispositif électronique portatif comprend un boîtier dans lequel sont montés distants des premier et second transducteurs. Un circuit processeur audio multimodal est configuré pour transmettre les sons du premier transducteur, dans un premier mode de fonctionnement, et d'émettre un signal audio composite à partir de l'énergie sonore reçue par les premier et second transducteurs, dans un second mode de fonctionnement. L'invention concerne en outre les terminaux mobiles et les procédés de fonctionnement des dispositifs électroniques portatifs.
