mobile phone or other mobile communication device . in one embodiment , the present invention utilizes a form of directional sound with a sealed side firing speaker to project the sound to a user &# 39 ; s palm for better sound with compact implementation . the directivity of the sound is combined with a palm - ear - wrist seal area to project the sound in sealed cavity of the user &# 39 ; s cusped hand . fig4 is a front view of a user 200 using a side firing speaker 202 in one embodiment of the present invention . the side firing speaker 200 fires the sound 204 at the bottom 206 of the user &# 39 ; s palm towards the user &# 39 ; s palm 208 clasped around the user &# 39 ; s ear 210 . the sound 204 emanating out at the bottom of the palm may have some directivity and be further contained by the user &# 39 ; s hand 212 and cheek 214 . the sound is directed towards the bottom of the palm 208 within the contained area of the clasped palm . the users clasped palm 208 and the user &# 39 ; s ear pinna contain and amplify the sound to the ear . this not only produces very good quality sound , it also minimizes the leak from outside the palm 208 . as illustrated in fig4 , the side firing speaker 200 fires the sound directly toward the clasped hand of the user . fig5 is a front view of the side firing speaker 200 firing the sound 204 at a steep 90 degree angle , hitting directly at the bottom of the palm and guided towards the clasped palm area of the user . the speaker 200 normally fires the sound straight in front of its surface . in one embodiment , an enclosure sits in front of the speaker and directs the sound to the side of the speaker . as depicted in fig4 , the palm 208 directs the sound . this side firing enclosure may be designed to either fire the sound sideways towards the palm or fire the sound directly in front for normal speaker mode operation . fig6 is a side perspective view of the speaker 200 with a flip open door 220 in one embodiment of the present invention . as depicted in fig6 , a dome type side firing chamber 222 directs the sound to the side of the speaker and towards the bottom of the user &# 39 ; s palm . the speaker includes the flip open door 220 on the top surface of the chamber 222 . sound fires directly in front of the speaker while the door is opened . in this configuration , there is minimal sound going towards the palm . this open door mode can be used for a speaker mode hands - free operation . when the door is closed , the speaker fires the sound to the palm , thereby providing a private mode . in another embodiment of the present invention , a slider tube 230 may be utilized . fig7 illustrates a front perspective view of a slider 230 located on top of a speaker 232 in another embodiment of the present invention . the slider may be a tube which is positioned on a guide 236 having slots 238 to accommodate side firing and top firing sound broadcasting . fig8 is a side view of the slider 230 in a closed position . in a closed position of the slider , the slots 238 are lined up so that the sound 204 goes directly from the speaker to the front of the speaker for hands - free speaker mode . fig9 is a side view of the slider 230 in the open position . in the extended or open position of the slider , the slots 238 are closed and the sound 204 travels through the slider and fires at the end to the bottom of the user &# 39 ; s palm . when the user is driving in a car , the bottom of the user &# 39 ; s wrist points towards the user &# 39 ; s face . the slots are designed for a hands - free mode which may direct the sound towards the driver . a speaker typically transmits sound through vibrations in the air . the present invention as discussed in fig1 - 9 discusses using directional sound to direct all the sound to the ear . however , the devices discussed in fig1 - 9 still leak sound to the external environment . this leakage can be minimized by using vibration speakers that make contact to the user &# 39 ; s jaw bone while the user &# 39 ; s palm is held against the ear . in one embodiment , a vibration speaker 240 is attached to the bottom of a wrist watch towards the bottom of the user &# 39 ; s palm . when the user holds the user &# 39 ; s palm to the user &# 39 ; s ear , the vibration speaker 240 makes contact with the jaw bone of the user . fig1 is a front view of the vibration speaker 240 positioned against a users jaw 242 . as illustrated in fig1 , the vibration speaker is held against the jaw 242 of the user . this contact to the jaw bone enables the transmission of the sound vibrations to the ear through the user &# 39 ; s skull bone structure . the vibrations between the wrist and jaw bone also reverberate within the confined area of the palm to produce a louder sound to the ear . the vibration speaker 240 illustrated in fig1 does not generate much sound until it makes contact with the facial bones ( e . g ., jaw ) of the user . to utilize the vibration speaker 240 as a speaker phone ( for hands - free mode ), a slider plate of glass or any vibrating material may be slid on top of the vibration speaker ( not shown ). this plate may act as a resonant vibrator and generate regular sound through the air . the vibration speaker may work as both a private hands - on bone conduction speaker and a hands - free loud speaker with a slide of a plate . in one embodiment , the present invention utilizes a wrist watch having a combination digital and analog display with a partial dial containing a digital display . fig1 is a front view of an electronic module 244 having a watch face 250 in one embodiment of the present invention . as illustrated in fig1 , the watch face 250 includes an area 252 providing for analog or mechanical movement located in the center of the watch with a surrounding area 254 having a digital printed circuit board ( pcb ) 256 . the analog movement drives the hands 260 and 262 of the watch . the pcb 256 may include a micro controller and digital circuits for driving a digital display and digital logic of the watch . fig1 is a front view of the electronic module 244 with the watch face 250 illustrating a partial view of an interior 270 of the watch face . the watch face includes a digital display 272 located in the center portion of the watch while a mechanical dial 274 is located surrounding the display . in an alternate embodiment , the watch face includes only the digital display 272 with the pcb without the analog mechanical movement . an issue with utilizing an analog / digital combination is associated with putting a hole in the middle of the display to allow the analog time hands to connect to the movement mechanism below . this hole is a technical problem in many displays as lcd technology does not support placing holes in the panel . in one embodiment , the analog watch mechanism is positioned in front of the digital display . fig1 is a top view of the watch face 250 in one embodiment of the present invention . the electronic display includes the digital display 272 with a watch movement mechanism 280 and the hands 260 and 262 overlaying the digital display . a top protective glass 282 or other transparent material may be placed over the entire electronic display . thus , it is no long necessary to place a hole in the digital display . as illustrated in fig1 , the watch movement mechanism 280 sits on top of the digital display 272 . the watch movement mechanism runs the hour and minute hands 260 and 262 . the watch top protective glass 282 sits in front of the mechanism . thus , the user would see the watch hands , mechanism and uncovered area of the display . by using a small watch movement mechanism , only a small portion of the digital display is hidden . the watch movement mechanism may be held in place on the display with a matching slot on the front surface of the display . the watch movement mechanism may also be held with other transparent mechanical supports connected to the watch face 250 . to conserve space and utilize the maximum battery life for the digital functions , the present invention may incorporate batteries in one or both , watch strap . fig1 is a top view of a wrist watch 290 having a battery 292 incorporated in straps 294 . fig1 is a side view of the watch 290 . in one embodiment of the present invention , a watch case 296 is extended with wings 298 on either side . these wings 298 , which may have an appearance of a metal watch strap , have a sealed water proof cavity to secure the battery 292 . in another embodiment of the present invention , a metal strap having connected large links may be utilized . each link may include an embedded small chargeable battery . these connected batteries in the links may provide enough capacity to drive the watch without consuming additional space outside the strap . in still another embodiment , the battery is embedded in a leather strap that carries a thin ribbon cable through the interior of the strap to transmit the battery power to the watch . furthermore , a vibrator motor 300 may be integrated into the bottom of the case 296 . the bottom of the watch case , which always makes full contact with the top of the user &# 39 ; s wrist , provides an ideal surface to indicate through vibration that a call is incoming . the batteries in the straps of the watch and the vibrator motor in the bottom of the watch case may be incorporated into any wrist watch and still remain in the scope of the present invention . the present invention may also utilize tilt sensors , gyros , or accelerometers 302 ( see fig1 ) to detect the orientation of the hand . gestures of the user &# 39 ; s hand may be used as an interface for controlling the watch . thus , specific gestures may correspond to specific operations on the mobile communication device . when a user lifts his hand and moves the palm to the user &# 39 ; s ear to answer the phone call or make a phone call , the orientation of the sensor 302 changes to a vertical axis . this change in orientation may be used to answer an incoming phone call . fig1 illustrates the orientation of a user &# 39 ; s hand 212 for answering an incoming phone call . when the user moves his hand down , this gesture can be used to mute the call . the user may use various hand gestures to control a call . for example , when a user lifts his hand when there is no incoming call , the sensor 302 in the watch senses this gesture , and interprets the gesture by the microcontroller module 102 to command that “ dial out ” screens be displayed on the digital display 272 . fig1 illustrates a user &# 39 ; s hand 212 twisting his hand to read the watch . when the user 200 twists his hand 212 to read the watch , the sensor 302 detects the tilt in the hand axis , fig1 is a side view of the watch 290 with the orientation shown in fig1 . this tilt is used to initiate a refresh command on the time in the digital display or illuminate the dial . a slight tilt can refresh time while a larger tilt may illuminate the watch . in another example , when the user makes a gesture of twisting his hand ( as he does while unlocking a physical door ), this twist is detected and used to unlock the locked screen on the watch . during jogging , a user typically swings his hands . the sensor 302 may be used to detect this jogging and send the detected movement to the microcontroller module to command that a health monitor screen of the watch be enabled when jogging is detected by the sensor . during an incoming call , shaking of the user &# 39 ; s hand can be used to reject the call . when a user moves his hands , such as when gesturing goodbye , this may be utilized to command the ending of a call . furthermore , when the user moves his wrist horizontally , this gesture may be used to command the movement of a mouse in an attached computer or smart device . a single accelerometer may be used to detect tilt in multiple axes to take multiple actions . these tilt - based actions not only gives the user convenience , where the user does not have to use menus , it may also save power by refreshing the time or switching on illumination of the watch only when desired , by the user . thus , a sensor or accelerator or plurality of such may be utilized to detect movement of the watch , send the detect movements to the microcontroller module 102 , and send an appropriate command to the watch . furthermore , the sensor may detect drastic movements , such as when a user falls , and transmits an emergency message or dials and calls a specified emergency number ( e . g ., 911 ) or other designated number . in another embodiment of the present invention , the watch may incorporate e - paper or memory lcd technology for use with the watch face 250 ( see fig1 and 20 ). e - paper display technologies are designed to mimic the appearance of ordinary ink on paper . unlike conventional backlit flat panel displays which emit light , e - paper displays reflect light like ordinary paper , making it more comfortable to read and giving the surface a wider viewing angle compared to conventional displays . the e - paper consumes power only during refresh . the display could be refreshed once a minute to update time or as desired dependent upon the connected mobile &# 39 ; s signal level or battery charge . this refresh may also be limited to only when the user reads the watch during the tilt of the user &# 39 ; s hand . the rest of the time the display would not consume any power . memory lcd technology works in a similar fashion as e - paper and may be used to display information on the watch . the watch utilizing e - paper technology may also provide a display similar to a physical clock dial . in normal operation , the e - paper display may be made to look similar to an analog clock with rotating hands . a dual pattern display can be achieved while the e - paper pattern is changed . the analog looking watch becomes digital only during call or when the digital functions are needed . in another embodiment of the present invention , the digital display 272 may be constructed of organic , transparent oled material , which may appear as a normal analog watch with transparent glass on top . in this embodiment , the digital display is a transparent glass which illuminates with a character display only during calls or when the digital functions are needed . the illumination of the oled glass also provides night time reading without use of an additional led . the tilt display automation may also be applied for the oled display . fig1 is a front view of the watch face 250 illustrating a first menu 320 display in one embodiment of the present invention . the display may utilize the oled material or the e - paper display described above . other visual types of displays may be utilized in other embodiments . the dial display of the watch may have a touch screen having a plurality of menu functions . the e - paper or transparent oled may display current action items for each of the menu functions . as depicted in the menu 320 , the display may show setup , call or silence in one segment , an answer or up scroll , in another segment , and a down or reject in another segment . fig2 is a front view of the watch face 250 illustrating a second menu 322 display in another embodiment of the present invention . in this second menu , one segment may be a setup selection , while another selection may be an answer command and another segment may be a reject command . during incoming calls , the menu functions may display commands of silence , answer or reject . the user may then push whichever command is desired . likewise , during an outgoing call , the menu functions of call , and up / down commands ( for scrolling numbers ) may be displayed . the present invention may split a watch into two separate components , a display module 400 and an audio / bluetooth module 402 , fig2 is a top perspective view of a watch 404 having the separated display module 400 and the audio / bluetooth module 402 . the display module may be located on top of the user &# 39 ; s wrist and the audio / bluetooth module located at the bottom of the user &# 39 ; s wrist . the display module may include a microcontroller unit ( mcu ) 406 and is attached to battery enclosure wings 410 on each side of the display module . a leather or metal strap 412 may include an embedded ribbon cable which connects the electronics within the display module 400 on top of the wrist with the electronics of the audio / bluetooth module 402 on the bottom of the wrist . the strap 412 may be designed with an offset so that the audio interface is offset with respect to the display module . additionally , this offset may help move the audio interface closer to the palm of the user for better audio firing . fig2 is a top view of the display module 400 and the strap 412 . the display module includes a watch dial 430 and may include a battery box 432 for retaining batteries . the audio / bluetooth module 402 is shown at the end of the strap 412 . the watch strap 412 may be designed in such a way that it can be locked in place around the wrist with slack . it can later be tightened by pulling the strap to make it a tight fit around the wrist . a magnetic latching mechanism may be provided between two ends of the open strap . once the magnets lock is in place , it provides a large loop around wrist . the strap is further pulled for a tight fit around the wrist using a buckle or other fastening device . fig2 is a front view of a portable speaker 500 attached to a watch 502 . fig2 is a top view of the portable speaker module 500 removed from the watch 502 . the compact speaker module 500 may utilize the vibration speaker 240 ( i . e ., bone conduction speaker ) with the wireless interfaces discussed above . the portable speaker module may include a compact battery 504 to last for a short period . this removable module 500 is attachable to the audio module at the bottom of the watch strap . during a call , the removable module is removed from the watch and held behind the user &# 39 ; s ear , concealed behind the ear pinna . this module 500 may communicate with the watch to play the phone audio channel . when connected to the watch , the module 500 may be charged from the higher capacity battery of the watch . although the present invention has been described as a wrist watch , the present invention
