Abstract:
An earpiece unit is held adjacent to or within a cell phone. The earpiece includes a microphone and speaker and is wearable in a user&#39;s ear. The earpiece is docked within the housing of a cell phone and can be used in the docked position to operate the phone. A user can push on the back of the earpiece to eject the earpiece from the phone housing so that the earpiece can be easily inserted into the user&#39;s ear. The user can be provided with a “pause” control on the cell phone that indicates to the cell phone system that a call is going to be answered. Upon activation of the “pause” control, the cell phone system can pause its efforts to establish communications and/or temporarily reduce the intensity of transmissions. A message is sent to the caller notifying that the call is about to be answered.

Description:
BACKGROUND OF THE INVENTION 
   Today&#39;s cell phones provide “earpiece” microphones and speakers as an accessory to the cell phone. Such earpiece units fit into, onto, or around the ear. The earpiece units are small and can be connected to the cell phone by a thin wire, or they can be wireless (e.g., Bluetooth, Wi-Fi or other radio frequency, infrared, etc.). These units are popular because they are lightweight, allow a user to have free hands, and place the cell phone unit away from the user&#39;s head. The latter effect is desirable among many users as there is a belief that cell phone emanations can be harmful. 
   Although the earpiece units work well and provide benefits, they have a drawback in that they are often awkward or cumbersome to put on quickly. Often a user must answer a phone call within a few rings and there is not enough time to put on, attach, activate, or otherwise handle an earpiece. Another problem is that the earpiece is a separate unit from the cell phone and the user must remember to bring the earpiece along, and have the earpiece handy when the cell phone is being used. 
   BRIEF SUMMARY OF THE INVENTION 
   One embodiment of the invention provides an earpiece unit that attaches, or mounts, adjacent to or within a cell phone. In a preferred embodiment, an earpiece includes a microphone and speaker (or other audio means for input and output, e.g., a transducer) and is wearable in a user&#39;s ear. The earpiece is docked within the housing of a cell phone and can be used in the docked position to operate the phone. A user can push on the back of the earpiece to eject the earpiece from the phone housing so that the earpiece can be easily inserted into the user&#39;s ear for remote use (i.e., away from the cell phone). 
   In the remote, or undocked, mode the earpiece unit can communicate with the cell phone by wired, wireless or other communication means. 
   The user can dock the earpiece by pushing the cell phone to the earpiece in a reverse maneuver from the undocking procedure. In a preferred embodiment, the user is provided with a “pause” control on the cell phone that indicates to the cell phone system that a call is going to be answered. Upon activation of the “pause” control, the cell phone system can pause its efforts to establish communications and the cell phone can go into a dormant, or low transmission state. This allows the user to put the cell phone to the user&#39;s ear without the danger of heightened power transmissions of the type typically used to set up a cell phone call. 
   In a preferred embodiment the cell phone system also reacts to the user&#39;s activation of the pause control by notifying the caller that the call will be answered imminently. An audible message such as “your call is being answered, please wait” can be sent to the caller. After circuitry in the cell phone detects that the user has ejected (undocked) the earpiece, and after a safety interval (e.g., 3 seconds) the cell phone resumes high power transmission with the cell phone system to establish a connection and to transfer voice and other information. At this point it is assumed that the user has positioned the earpiece properly and is ready to talk. 
   Another aspect of the invention allows the pause control to be located remotely from the cell phone, such as on a ring, wristband, wristwatch, steering wheel of a car, etc. so that a user can easily and quickly notify the cell phone that the call will be answered. When a remote pause control is activated the cell phone system may provide an extended interval of time for a user to get situated (e.g., earpiece on) to receive the call. 
   Another embodiment of the invention uses a cell phone holder with a clip or other carrier for the earpiece. This approach does not require that the earpiece is integral with the cell phone so that the carrier and earpiece can be after market products. The carrier acts merely to hold the earpiece adjacent to the cell phone using a clip, bracket, shutter, or other method or device. 
   One version of the carrier is designed to allow wire-connected earpieces to store the wire within a compartment. The earpiece is also held in the compartment and the other end of the wire is plugged into the cell phone. The earpiece in the docked mode held at about the same position as a speaker mechanism that is integral with the cell phone so that the user can use the phone and earpiece when the earpiece is docked. The earpiece can be undocked and inserted into the user&#39;s ear in a single motion by pressing on the back of the earpiece with a finger, similar to the embodiment where the dockable earpiece is inside the cell phone housing. 
   In one embodiment the invention provides an apparatus for using a portable phone, the apparatus comprising an audio transducer for generating audible sound; and a holder for holding the audio transducer adjacent to the portable phone. 
   In another embodiment the invention provides a method for answering a portable phone, the method comprising activating a control signal prior to speaking on the portable phone, wherein the control signal indicates that an incoming call will be answered. 
   In another embodiment the invention provides a method for providing a microphone/speaker device in association with a portable phone, the method comprising removably affixing the device adjacent to the portable phone. 
   In another embodiment the invention provides an apparatus for answering a portable phone, the apparatus including a control for generating a pause signal; and a playback circuit responsive to the pause signal for sending a predefined message over a cellular network.

   DETAILED DESCRIPTION OF THE INVENTION 
     FIG. 1  shows a cell phone with a dockable earpiece contained within a housing. 
   In  FIG. 1 , cell phone  100  includes housing  102 . Within housing  102  is earpiece  110 . Although not shown in  FIG. 1 , portions of earpiece  102  can be completely within the confines of the cell phone housing while other portions can protrude from the housing. The housing has sufficient cut outs, or other mechanisms (e.g., doors, flaps, slots, moveable coverings, etc.) so that the earpiece can be easily pushed out from the housing. 
     FIG. 2  shows a side view of the cell phone of  FIG. 1 . In  FIG. 2 , it is possible to see the different portions of earpiece  110  that are within and without housing  102 . In general, items with the same reference number in different Figures are intended to represent the same object. 
   In  FIG. 2 , front earpiece portion  112  protrudes from the front of the cell phone housing. Back earpiece portion  114  protrudes from the back of the housing, while middle portion  116  is within the housing. Naturally other embodiments can have more or less portions protruding or within the housing as desired. As shown in other embodiments, below, the entire earpiece can be outside of the cell phone housing. Much of the orientation of the earpiece within the cell phone housing depends upon both the cell phone design and the earpiece design. Any manner of layout, orientation, shape, or other characteristics of the earpiece and cell phone are possible. 
     FIG. 3  illustrates a user in the process of undocking the earpiece. The user pushes on the back of the earpiece with a finger to dislodge the earpiece from the cell phone and to easily put the earpiece into the user&#39;s ear. One embodiment uses an earpiece that is shaped to a user&#39;s ear. As is known in the art, the shape of the rubbery and somewhat flexible earpiece is snug enough within the ear contours so that the earpiece will stay in place. Other types of earpieces may have a portion that loops around, or hangs from, the outer ear. Yet other earpieces may fit entirely inside of the ear and not rely on contours of the outer ear to stay in place. In general, any type of earpiece design can be used with the present invention. 
   The earpiece can be secured by friction or by any mechanical means such as by a clasp, spring grips, moveable pin, detent protrusion, etc. Any approach to detachably securing the earpiece to the cell phone in the docked position, while still allowing undocking with slight finger pressure is acceptable. Note that the cell phone can be used as normal when the earpiece is docked as the earpiece approximates the speaker position of a standard cell phone (i.e., at the top of the cell phone). Other approaches can have a separate speaker in the cell phone to emit sound if it is not desirable to use the earpiece speaker when the earpiece is docked. 
     FIG. 4  shows cell phone  100  adjacent to user  120 &#39;s ear. Note the position of earpiece  110  oriented at approximately the correct angle for earpiece insertion to the ear according to the shape of the earpiece and contour of the outer ear. Where different types of earpieces are used, such positioning may not be critical. However, where an earpiece that requires correct angle positioning is used it is desirable to make the angle of the earpiece align with the natural angle that a user would hold the cell phone. 
     FIG. 5  illustrates the earpiece undocked from the cell phone and set into the user&#39;s ear. Once the earpiece is set the cell phone can be removed, such as held in the user&#39;s hand at arm&#39;s length. In the example of  FIGS. 1-5  the earpiece is of the wireless type. However, a wired earpiece can also be used, in which case a wire would connect the cell phone with the earpiece. The wire can be unrolled from a loop as the wire is drawn out when the cell phone is moved away from the earpiece. The wire can be brought back into the cell phone housing by a take up spindle or by other means. 
     FIG. 6  illustrates an earpiece carrier. Earpiece carrier  200  can be an after-market add-on to a standard cell phone. The carrier can clip onto the cell phone by designing the carrier to close tolerance with the cell phone dimensions. If the carrier is slightly flexible plastic then the plastic can be separated at one or more points to allow the cell phone to be placed into the carrier. When pressure is released from the points the carrier will resume its shape and close around the cell phone to securely hold the cell phone. 
   The carrier of  FIG. 6  is designed to house a wired earpiece having an earpiece body  210 , connector  212  and cord  214 . As shown, the carrier surrounds connector  212  which is plugged into the cell phone so as to make an electrical connection. Cord  214  is irregularly coiled or folded into the compartment of the carrier above cell phone  202 . Earpiece body  210  is secured to the carrier by hinged doors that are discussed below. 
     FIG. 7  shows a side view of the earpiece carrier of  FIG. 6 . 
   In  FIG. 7 , a user can push on the back of earpiece body  210  with a finger to force the earpiece body from carrier  200  and into a user&#39;s ear, similar to the approach discussed above in connection with  FIG. 3 . Note that even when the earpiece of  FIG. 7  is docked that it is still useable by a user as it is located in a position near the top of cell phone  202  where the speaker is normally located. Also, the earpiece microphone can pick up vibrations and convey them as voice information through the earpiece to the cell phone. Such vibrations will be clearer if the earpiece is allowed to protrude somewhat toward the front of the phone so that the earpiece body can contact the user&#39;s ear or other facial structures more completely. Other approaches to earpiece microphones can use different techniques to allow the user to operate the cell phone while the earpiece is in the docked position. For example, a small microphone can be used in the earpiece oriented such that voice transmission is not primarily dependent upon transmission by vibration through earpiece or cell phone materials. 
   In many cell phones the act of inserting a plug, such as plug  212  of  FIG. 6 , into the cell phone causes the built-in microphone and speaker of the cell phone to be inoperable. In such a case, the user will have to use the earpiece so it will be most practical if the earpiece is usable in either docked or undocked positions. In other cell phones there may be a selector control, such as a button or switch, that allows a user to select earpiece or non-earpiece (i.e., cell phone built in microphone and speaker) operation. 
     FIG. 8  shows a perspective view of the top portion of the carrier of  FIGS. 6 and 7 . 
   In  FIG. 8 , earpiece body  210  has been pushed out of carrier  200 . The pushing out of the earpiece body causes doors  222  and  224  to rotate outward in the direction of the arrows. The earpiece is set into the user&#39;s ear, as before. As the carrier and cell phone are brought away from the earpiece set in the user&#39;s ear the cord is played out through spaces between the doors. In a preferred embodiment the doors are hinged stiffly enough to hold the earpiece body and cord inside the compartment of the carrier, yet not so stiff that the doors can not be easily opened by forward pressure on the back of the earpiece—as with a finger. In one embodiment the user can manually stuff the cord back into the compartment. Other embodiments can use a spring take-up reel system or other approach to automatically retract the cord. 
   Note that any shape, size and design of compartment and carrier can be employed. It is possible (and may be desirable) to merely have a carrier with a large enough compartment to hold the earpiece and cord. In such a case the user can simply open up the compartment by hand, remove the earpiece, and set the earpiece into the ear. 
     FIG. 9  shows an earpiece carrier with a clip. 
   In  FIG. 9 , cell phone  310  is provided with carrier  322  that attaches to the cell phone housing. Clip  320  is formed into the carrier so that earpiece  300  can be detachably secured in proximity to the cell phone. In  FIG. 9 , the back of cell phone  310  is shown. The earpiece is clipped onto the back of the cell phone so as not to obstruct the user from controls on the front of the cell phone. 
     FIG. 10  shows the carrier of  FIG. 9  in a side view. 
   In  FIG. 10 , carrier  322  includes clip  320  to hold earpiece  300  adjacent to cell phone  310 . This approach may be desirable as a simple solution to keep an earpiece handy, especially when the size of the earpiece is comparably large to the size of the cell phone. In general, however, any type of clip or other means (e.g., spring clip, adhesive or sticky material, Velcro, friction, etc.) can be used to detachably hold the earpiece adjacent to the cell phone. 
     FIG. 11  illustrates a pause button feature of an embodiment of the present invention. 
   In  FIG. 11 , cell phone  406  receives a call from caller  420 . The call can be placed normally via cell phone network  410 . Other networks, such as the standard phone systems (aka “plain old telephone system” or POTS), voice over Internet Protocol (VoIP), radio transmission or other communication links or systems can also be used. Cell phone  406  can alert a user normally as with a ring or vibration. Pause button  404  is shown on ring  402 . In this case the pause button is on the bottom of a ring worn on one of the four fingers of a hand so that the button can be activated with a thumb. In other embodiments the button can be any type of control (e.g., switch, slider, motion detector, voice detector or voice recognition unit, etc.) affixed or associated with any suitable object. Preferable the object is wearable such as jewelry, a wristwatch, etc. so that the pause button is easily accessed even when the cell phone may be out-of-the-way such as in a purse, pocket, luggage, etc. 
   Even where the cell phone is easily reachable it may be desirable for a user to use the pause button approach to answering a cell phone in order to reduce the user&#39;s exposure to cell phone radiation. When the pause control is activated a signal is sent to the cell phone. The signal can be radio frequency, infrared, etc. In some embodiments the pause button can be located on the cell phone itself as it can still provide benefits such as allowing the user more time to talk on the cell phone, plug attachments into the cell phone, or for other reasons. 
   When cell phone  406  receives the pause control signal it can handle the incoming call in a number of ways. A first way is to automatically answer the call at the cell phone and present the caller with a pre-recorded message such as “just a minute—your call is being answered.” In this case there is no reason to have any special processing or modification to a standard cell phone network such as cell phone network  410 . The user can take as much time as the caller will stand and then begin speaking. 
   A second approach is for an indication of the pause signal to be sent to cell phone network  410  so that the cell phone network can permit a break in any expected cell phone transmissions. The cell phone can also go into a suspend (i.e., paused) mode where it is acceptable to have a halt in transmission broadcast to the cell phone network. This will allow a user with a docked earpiece to bring the phone to the user&#39;s ear and insert the earpiece without full-strength broadcast from the cell phone. The pause in transmission (or lowered power transmission) can occur after the cell phone transmits the automatic message to the caller. A light can be used to indicate to the user when the cell phone has gone into a paused state during receiving a call. Alternatively, the pause signal can be sent to the cell phone network where a “please wait” message is generated for the caller. In this last case there is no need for the user&#39;s cell phone to generate the message so a delay due to sending the message is avoided. 
   One embodiment uses a sensor to detect when a docked earpiece is being ejected for placement into a user&#39;s ear. Upon detection, a pause signal is generated and the actions described above can be taken. In a case where the user is making an outgoing call transmission from the cell phone will not start until the user performs other actions, such as dialing a number, so the use of the pause signal is not necessary. 
   Although embodiments of the invention have been described primarily with respect to a cell phone, any type of communication device (e.g., walkie talkie, personal digital assistant, intercom, radio transmitter, etc.) can benefit from features of the invention. Other consumer electronics products such as audio players, recording devices, computers, etc., can similarly benefit from features of the invention. 
   Although carriers and compartments have been presented for holding earpieces adjacent to cell phones, other items may similarly be held or placed. For example, a paper address book, computer, audio player, keys, batteries, etc., can be attached to a cell phone by means of the carrier assembly. 
   Any suitable programming language can be used to implement the routines of the present invention including C, C++, Java, assembly language, etc. Different programming techniques can be employed such as procedural or object oriented. The routines can execute on a single processing device or multiple processors.
