CA 2552665

An improved handheld electronic device has a case with an elongated cavity formed therein. An audio transducer is in fluid communication with the cavity, and a number of sound openings are formed in the case and are in fluid communication with the cavity and with the atmosphere surrounding the handheld electronic device. The sound openings are generally spaced from a central region of the audio transducer to space the sound openings generally farther from an edge of the case than the audio transducer. The cavity is configured to form a Helmholtz resonator that enables the communication of sound through the cavity between the audio transducer and the sound openings. The spacing of the sound openings from an edge of a case helps a user to form a seal between the case and the user's ear to enable sound from the sound openings to enter the ear and to be perceived by the user.

L'invention est un dispositif électronique portatif optimisé doté d'un boîtier comportant une longue cavité. Un transducteur audio est en libre communication avec la cavité et un certain nombre d'ouvertures sonores sont formées dans le boîtier et sont en libre communication avec la cavité et l'atmosphère entourant le dispositif électronique portatif. Les ouvertures sonores sont généralement éloignées d'une région centrale du transducteur audio afin de placer les ouvertures sonores généralement plus loin d'un bord du boîtier que le transducteur audio. La cavité est configurée pour former un résonateur de Helmholtz permettant la communication du son à travers la cavité entre le transducteur audio et les ouvertures sonores. L'espacement des ouvertures sonores à partir d'un rebord de boîtier aide un utilisateur à former un joint entre le boîtier et l'oreille de l'utilisateur afin que les ouvertures sonores puissent être perçues par l'utilisateur.
