HANDHELD ELECTRONIC DEVICE HAVING OFFSET SOUND OPENINGS |
摘要 |
An improved handheld electronic device has a case with an elongated cavi ty formed therein. An audio transducer is in fluid communication with the cavit y, and a number of sound openings are formed in the case and are in fluid communicati on with the cavity and with the atmosphere surrounding the handheld electronic device. T he 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.
