Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates in general to the field of information handling system audio playback, and more particularly to a method and system for retractable earphones integrated in an information handling system.

[0003] 2. Description of the Related Art

[0004] As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

[0005] Multimedia applications are an increasingly popular use for information handling systems. For instance, video and audio output are presented through an information handling system display and internal speakers or are presented through external peripherals, such as projector and speaker systems. Portable or laptop information handling systems are particularly useful for multimedia applications. For example, a business person traveling for a presentation is able to prepare and practice the presentation on a portable information handling system while traveling and then use the portable information handling system to perform the presentation by interfacing with external peripherals at the presentation site. In addition to business applications, portable information handling systems provide multimedia entertainment, including the presentation of videos, such as DVDs, and music in a convenient and compact system. For instance, while writing a presentation a traveling business person might simultaneously listen to a music CD.

[0006] One difficulty with audio output from an information handling system is that the use of internal speakers often is not practical since it disturbs others near the information handling system. For instance, a business traveler on an airplane typically is unable to play audio files over the internal speakers of an information handling system without disturbing other passengers. One alternative for listening to audio files without disturbing other travelers is to listen to the audio files with earphones instead of internal speakers. However, in order for an information handling system user to use earphones, the user generally must carry the earphones as extra equipment that interfaces with an earphone jack or port. In addition to the hassle presented by carrying earphones as extra equipment, the user often must untangle the earphone cords. Further, once the user is finished, the user typically must roll up the earphone cords and store the earphones in a location where the earphones will be available for use when next needed by the user.

SUMMARY OF THE INVENTION

[0007] Therefore a need has arisen for a method and system which conveniently stores and makes available earphones for use with an information handling system.

[0008] A further need exists for a method and system which integrates earphones with an information handling system to allow selective replacement of the integrated earphones with other earphones.

[0009] In accordance with the present invention, a method and system are provided which substantially reduce the disadvantages and problems associated with previous methods and systems for interfacing earphones with an information handling system. An earphone storage mechanism stores earphones that are operable to output audio signals as audible sounds. An audio output selector interfaced with the earphone storage mechanism selectively interfaces audio signals with earphones under a predetermined condition, such as the presence or absence of the earphones in the earphone storage mechanism.

[0010] More specifically, a portable information handling system has electronic information processing components that generate audio information output. One or more speakers of the information handling system generate audible audio output from the audio information output signals. An earphone storage mechanism accepts earphones in earphone storage openings having an audio output selector that detects the insertion or removal of earphones and that selects the speakers for outputting audible audio output if the earphones are inserted in the openings and selects the earphones for outputting audible audio output if the earphones are removed from the openings. The earphone storage mechanism has a reel that extends or retracts earphone cords from within the information handling system. Earphone couplers proximate the end of the earphone cord removably couples earphones to the earphone cord to allow replacement with alternative earphones. In one embodiment, a wireless transmitter associated with the information handling system transmits audio information signals to a wireless receiver associated with the earphones when the earphones are removed from the earphone storage mechanism.

[0011] The present invention provides a number of important technical advantages. One example of an important technical advantage is that earphones are conveniently stored and made available for use with an information handling system. Since the earphone storage mechanism is integrated with the information handling system housing, earphones remain conveniently available for use. The earphone cord is extended and retracted with the earphone cord reel so that tangles and other difficulties with cord storage are avoided. Alternatively, a wireless transmission initiated by removal of the earphones from the storage mechanism eliminates the need for the earphone cord.

[0012] Another example of an important technical advantage of the present invention is that earphones integrate with an information handling system to allow selective replacement of the integrated earphones with other earphones. Earphone couplers removably couple each earphone to the earphone cord so that alternative or replacement earphones may be integrated with the information handling system, allowing a user to replace original equipment earphones with aftermarket earphones. Alternatively, earphone couplers removably couple each earphone with a wireless receiver so that alternative or replacement earphones may be interfaced with the wireless transmitter of the information handling system.

DETAILED DESCRIPTION

[0016] Audible audio output from an information handling system is selectively provided by internal speakers or integrated earphones so that earphones are readily available to a user of an information handling system. For purposes of this application, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.

[0017] Referring now to FIG. 1, a side cutaway perspective view of a portable information handling system 10 having an integrated earphone storage mechanism 12 is depicted. Portable information handling system 10 outputs audible audio information from internal speakers 14 or integrated earphones 16 depicted in FIG. 1 as retracted and stored in earphone storage mechanism 12. Portable information handling system 10 houses electronic components that generate multimedia signals, such as from video or audio files, for presentation of video information on display 18 and output of audio information from speakers 14 or earphones 16. Earphone storage mechanism 12 detects the insertion and storage of earphones 16 to select output of audio information from speakers 14 and detects the removal of earphones 16 to select output of audio information from earphones 16. In one embodiment, audio signals are transmitted to earphones 16 through a wireless transmitter 20, such as an 802.11b standard transmitter, and converted to audio output by a wireless receiver associated with earphones 16. In another embodiment, audio signals are transmitted to earphones 16 through an earphone cord retracted into and extended from earphone storage mechanism 12.

[0018] Referring now to FIG. 2, a perspective cutaway view of earphone storage mechanism 12 configured to store an earphone cord 22 is depicted. Earphone storage mechanism 12 integrates within portable information handling system 10 by, for instance, coupling a screw 24 into portable information handling system 10 and interfacing earphone cord 22 with electronic components of portable information handling system 10 that generate audio signals. Earphone cord 22 is stored by retraction into an internal earphone cord reel 26 that has a spring bias to retract earphone cord 22. Earphone cord 22 is extended from earphone cord reel 26 by pulling on earphone cord 22 and is maintained in the extended position by an internal detent that is released by a tug on earphone cord 22. Thus, cord reel 26 stores earphone cord 22 internally within portable information handling system 10 in a manner that makes earphones 16 readily and conveniently available for use to selectively output audio information.

[0019] Selection of speakers 14 or earphones 16 to output audio information is accomplished with an audio output selector 28 disposed within an earphone storage opening 30. Earphone storage openings 30 are sized and shaped to securely accept earphones 16 in a removable manner, such as with a clip spring or other securing device. When an earphone 16 is inserted in an earphone storage opening 30, audio output selector 28 is depressed to switch to audio output from speakers 14. When an earphone 16 is removed from an earphone storage opening 30, audio output selector 28 is released to switch to audio output from earphones 16. In an alternative embodiment, a reel position detector 32 determines whether earphones 16 are retracted or extended based on the position of cord reel 26 and selects audio output from speakers 14 if a predetermined amount of earphone cord 22 is extended or selects audio output from earphones 16 if less than the predetermined amount of earphone cord 22 is extended.

[0020] Integrated earphones stored in an integrated earphone storage mechanism 16 improve the convenience of listening to audio output from an information handling system. In order to allow greater user flexibility in the selection of earphones 16 by a user of portable information handling system 10, an earphone coupler 34 removably interfaces earphones 16 with earphone cord 22. For instance, earphone couplers 34 are jacks or plugs that couple with earphones 16 to communicate audio signals to earphones 16 and that release earphones 16 to allow replacement with alternative earphones, for instance including replacements of failed earphones or alternative earphones having a desired user quality. Earphone coupler 34 is proximate earphone 16 to reduce interference of earphone coupler 34 with storage and retraction of earphone cord 22, however, earphone coupler may be located along the length of earphone cord 22. In an alternative embodiment, earphones 16 are replaced with other earphones by replacement of cord reel 26 or earphone storage mechanism 12 with a different earphone cord and earphone set. Replacement of wireless earphones is performed by interfacing the replacement earphones with the wireless receiver.
