BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates generally to hand-held, portable electronic devices, and more particularly, to providing a retainer in a hand-held, portable electronic device for retaining a wireless accessory.
2. Description of the Related Art
Increasingly use to hand-held, portable electronic devices, such as a processor or controller based devices including hand-held, portable computers, hand-held multi-media players, music players, cellular phones, hand-held wired and/or wireless communication and/or computing devices, hand-held pocket computers, and personal digital assistants is becoming widely popular. As a result, use and exchange of electronic entertainment content and information is not only a trend anymore but a norm and a convenient way of experiencing multi-media content such as music and video, conveying information including electronic mail messages between users of wired and/or mobile communication devices. Many commercial enterprises, media service providers or network operators, Internet service providers and businesses use Internet to disseminate electronic multi-media content (textual, graphic, music and video files) over a connected mesh of wired and/or wireless network users. For example, several of these entities usually provide access to multi-media content and services on the Internet via websites and web browsers.
Users of the hand-held, portable electronic devices obtain and store a variety of electronic multi-media content such as music and video files on their hand-held, portable devices. Likewise, users of networked devices wired and/or wireless exchange electronic messages to communicate with other users. To use the hand-held, portable electronic devices, an audiophone comprising headphone(s) and/or microphone is provided for users. In general, for listening to electronic multi-media content such as music and video files, a pair of stereo headphones is provided with the hand-held, portable electronic devices. For the hand-held, portable networked, wired and/or wireless communication and/or computing devices, a headphone with a microphone is provided. Examples of headphones and/or microphones include a wired or a wireless set of audio devices.
While the wireless headphones and/or microphones comprise a headphone and/or a microphone, the wired headphone(s) and/or microphone comprise a pair of stereo audio cords with a set of micro headphones at one end and an audio male connector pin on the other end, both face a similar set of issues relating to their storage for reuse, i.e., when not being used by users. In particular, the audio cords are a few feet long so that a user can conveniently use the headphones and/or microphones. Since these audio cords are relatively soft and flexible they get entangled when the headphones and/or microphones are not being used. That is, storage of the headphones and/or microphones with a relatively long and flexible audio cord with headphone speaker(s) attached to its end is a messy affair. With regard to the wireless headphones and/or microphones, because of their wireless convenience it is relatively easy to misplace, damage, or loose them when they are not being in use. In this manner, storage for reuse of both the wired and/or wireless headphones and/or microphones of the hand-held, portable electronic devices becomes quite a challenge when an audiophone is not put to use by wireless users or it discharges rather quickly due to a constant use and need frequent recharging.
A wireless device accessory is a wireless communication-enabled accessory that can electronically, i.e., wirelessly communicate with a wireless communication-enabled device over a wireless communication link.
With regard to wireless device accessories such a stylus or a Bluetooth headset, because of their wireless convenience it is relatively easy to misplace, damage, or loose them when they are not being in use. In this manner, storage for reuse of wireless device accessories of the hand-held, portable electronic devices becomes quite a challenge when a wireless device accessory is not put to use by users.

Examples of the first portion 215 a-215 b of the surface 210 of the cell phone housing include a cavity 215 having a pair of hollow bubbles so shaped to receive a corresponding solid bubble pair, respectively. Examples of the second portion 220 a-220 b of the retainable wireless audiophone 105 a include a plug 220 having a pair of solid bubbles capable of snugly latching to the corresponding hollow bubble shaped to receive a respective solid bubble of the pair of solid bubbles. However, persons of an ordinary skill would appreciate that the retainer assembly 212 may be formed of many known shapes and structures by having the benefit of this instant disclosure based on one or more factors including a desired application and its operation, location on the cell phone 200. For example, an arrangement of the retainer assembly 212 may comprise the plug 220 and cavity 215. This arrangement may use a known stylus and an associated receptacle structure to securely receive and retain the retainable wireless audiophone 105 a with the cell phone housing 205 at the cell phone 200 by using a mating wedge or tapered forms for the plug 220 and a hollow cone-shaped or wedge-shaped receptacle for the cavity 215 instead of the bubbles based configuration.

The cell phone 200 may comprise a baseband unit 230 for digital processing the information signal (voice, data, or image) in the frequency range before being modulated onto a carrier or demodulated after reception by using a signaling technique in which the signal is transmitted in its digital form and not changed by modulation techniques. The baseband unit 230 may comprise a baseband processor 235 for use in a communications system, for example, wireless communications systems and, more particularly, toward baseband processing of communication channels. For example, the baseband processor 235 may be suitable in the United States for a wireless phone service offered in both the cellular (approx. 800 Mega Hertz (MHz)) and PCS (Personal Communications Services) (approx. 1900 MHz) frequency bands in a dual-band phone.
When digital speech represented by a series of bits, which are modulated and transmitted from a base station (not shown) to the cell phone 200, and vice versa, the cell phone 200 may demodulate the received waveform to recover the bits as originally transmitted, and the recovered bits are then converted back into speech. The baseband unit 230 may enable data services, such as E-mail, Internet access, etc., that require digital communications.
In operation, the baseband unit 230 may use one or more types of digital communications systems. For example, FDMA (Frequency-Division-Multiple-Access) systems divide the radio spectrum into a plurality of radio channels corresponding to different carrier frequencies. TDMA (Time-Division-Multiple-Access) systems further divide the carrier frequencies into time slots. D-AMPS (Digital Advanced Mobile Phone System), PDC (Pacific Digital Cellular), and GSM (Global System for Mobile communications) are examples of digital TDMA cellular systems. Alternatively, if the radio channel is wide enough, multiple users can use the same channel using spread spectrum techniques and CDMA (Code-Division-Multiple-Access). IS-95 and J-STD-008 are examples of wireless systems incorporating CDMA standards.
The baseband unit 230 may comprise a RF interface 240 to interface with the RF unit 225. The baseband unit 230 may further comprise a controller 245 and a system connector 250.

Referring to FIG. 13, it schematically illustrates details of the device battery charger circuit 1200 shown in FIG. 12 that replenishes the device battery 1115 of the hand-held, portable electronic device 100 i such as a cell phone according to one embodiment of the present invention. In one embodiment of the present invention, the device battery charger circuit 1200 may be a current-limited voltage source. The device battery charger circuit 1200 may provide to a cell phone' battery packs in the battery 3.6-6V DC and 180-200 mA current for charging. The device battery 1115 may comprise one to three Nickel Cadmium (NiCd) cells, each having 1.2V rating. A 12V input with current (1.8A) may charge the battery connected across the output terminals. The device battery charger circuit 1200 may monitor the voltage level of the device battery 1115. The device battery charger circuit 1200 may automatically cut off the charging process when its output terminal voltage increases above the predetermined voltage level.
The device battery charger circuit 1200 may comprise a Timer IC NE555 to charge and monitor the voltage level in the device battery 1115. Control voltage pin 5 of IC NE555 is provided with a reference voltage of 5.6V by zener diode ZD1.

When a discharged cell phone battery is connected to the device battery charger circuit 1200, the voltage given to trigger pin 2 of IC1 is below I/3Vcc and hence the flip-flop in the IC is switched on to take output pin 3 high. When the device battery 1115 is fully charged, the output terminal voltage increases the voltage at pin 2 of IC1 above the trigger point threshold. This switches off the flip-flop and the output goes low to terminate the charging process. Threshold pin 6 of IC1 is referenced at ⅔Vcc set by VR1. Transistor T1 is used to enhance the charging current. Value of R3 is critical in providing the required current for charging. With the given value of 39-ohm the charging current is around 180 mA.
The device battery charger circuit 1200 may be constructed on a small general-purpose PCB. For calibration of cut-off voltage level, use a variable DC power source. Connect the output terminals of the circuit to the variable power supply set at 7V. Adjust VR1 in the middle position and slowly adjust VR2 until LED1 goes off, indicating low output. LED1 should turn on when the voltage of the variable power supply reduces below 5V.
