Embodiment Construction

[0026] figure 1 An improved hand-held electronic device 4 is generally indicated in , and in figure 2 It is schematically depicted in . The example handheld electronic device 4 includes a housing 6 on which operating means including input means 8 , output means 12 and processor means 16 are placed. The processor device 16 includes a processor 18 and a memory 20 . Processor 18 , which may be, for example and without limitation, a microprocessor (μP), responds to output from input device 8 and provides output signals to output device 12 . Processor 18 is also interfaced with memory 20 . The memory 20 may be any one or more of RAM, ROM, EPROM, EEPROM and / or other storage devices.

[0027] The input means 8 comprise a schematically depicted keyboard placed on the housing 6 . Examples of handheld electronic devices include US Patent Nos. 6,452,588 and 6,489,950, which are hereby incorporated by reference.

[0028] Such as figure 1 As can be seen in , the cabinet 6 has a p...

Abstract

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.

Description

technical field [0001] The present invention relates generally to handheld electronic devices, and more particularly, to a handheld electronic device having a plurality of sound openings spaced from an audio transducer. Background technique [0002] A variety of handheld electronic devices are known. Examples of such handheld electronic devices include, for example, personal data assistants (PDAs), handheld computers, two-way pagers, cellular telephones, and the like. While many of these handheld devices are stand-alone devices that do not communicate with other devices, many handheld electronic devices also have wireless communication capabilities. [0003] Generally, handheld electronic devices are designed to be portable, and thus have a relatively compact configuration. As technology advances, handheld electronic devices are constructed with smaller and smaller form factors, but with more and more applications and features built onto them. [0004] Certain handheld el...
