The body part can include a means for transmitting communication signals.

Description: PORTABLE COMMUNICATION DEVICE. This invention relates to a portable communication device, at least part of which can typically be worn on the anatomy of a person such as the ear and in particular to a device which includes a detachable part which is still connected to the device but not by any physical connecting means. Devices are known for use by a person to listen to prerecor¬ ded or received radio signal information which is relayed to the person by a speaker mounted in the device. The device can be provided with any, or all of, controls for controlling the volume of information sent through the speaker; the playing, stopping, fast forward or rewind of prerecorded information; and the tuning of a receiver to receive information at a certain frequency. Another well known type of communications device is the portable, or mobile, phone and a common problem with the portability of these devices is that they are required to be provided with integral mouth and ear pieces. Even when the ear piece and mouthpiece are provided at the extreme ends of the device or the mouthpiece is provided as part of a flap which is unfolded for use, the size of the phone is deter¬ mined by the requirement to have the spaced apart mouthpiece and ear piece in a manner that the device can be comfortably used. The aim of the current invention is to provide a device which can incorporate a detachable part which can be placed to the ear for use, but preferably attached to the ear to be ear held and a part which provides further utilities wherein the same can be used as a communication device to allow communication functions to be provided such as any, or any combination of paging, 2-way paging and/or mobile telephone or radio functions, thus providing a device which can have the feature of being usable to transmit information by the wearer of the device. In a further feature the device can also be held in an unobtrusive stored position and worn by the wearer such as, for example, as part of a wrist watch, until a signal is received wherein at least part of the device can, if the wearer so wishes, be removed and placed on their ear to receive the message. Thus the device can be split into two parts, a body part which includes the mouth¬ piece and which can be used removed from the other part which includes the ear piece. The present invention, in a first aspect, provides a commu¬ nication device including a means for receiving a communica¬ tions signal and a speaker for relaying the communication received to the user and said device includes a first de¬ tachable part and at least a second part and wherein the first part is provided to be retained on, and/or placed to, the ear of the user in use such that in an in use position the first part is exposed for use remote from the remainder of the device. The detachable part is physically remote from the body part of the device in that it is not required to be physically connected to the body part of the device when in use. In one embodiment the first part is shaped with retaining means as an integral part thereof to allow the first part to be retained on the ear. Preferably the retaining means con¬ tact directly with the ear only and require no other reten¬ tion means to be provided and are not required to be in contact with any other part of the wearer's body. In one embodiment the retention means are retracted when the device is in a stored position. In one embodiment the device in a stored position is provided with a body part with a strap to be worn in a manner similar to a wrist watch. In one embodiment the device is provided as part of a wrist watch with the part to be worn on the ear located around the face of the same. In an alternative embo¬ diment the device is stored by being hung as a pendant such as from a chain, cable or wire. In one embodiment the cable, chain or wire can act as an aerial for the device to receive communication signals therefor. In one embodiment the device is provided with a sound and/ or light emitter to emit a sound or light when a signal is received and a signal receiver to either store or simultan¬ eously relay the signal and information received. When the information is stored the same can be played back once the person has placed the detachable, first part on their ear. In a further aspect of the invention there is provided a communications device of at least two parts for sending and receiving information, said device including a signal re¬ ceiver and a signal emitter to enable information to be received and information to be transmitted from the device thereby providing a two-way communications device and wherein a first part, including a speaker, is detachable from the device to be placed to or on the ear of the user for listen¬ ing to the information received. Typically the detachable part comprises a speaker, an infor¬ mation signal receiver and optionally a signal storage means, and a shaped retention portion to allow the same to be re¬ tained on the wearers ear. The detachable part is typically 96/21307 PCI7GB96/00011 provided with a receiver to receive information emitted from the remainder of the device and/or signals received directly from the source of the broadcast signal. In a further aspect of the invention there is provided a communications device which includes a first part which can be moved to the ear and/or mouth and a second part, and wherein the second part is capable of receiving and/or send¬ ing communication signals to allow information to be relayed via the first part to and/or from the user. In one embodiment the communications device includes at least two parts for sending and receiving information, said device including a signal receiver and a signal emitter wherein said device is provided for the reception and emission of telecom¬ munication and/or radio signals to allow the device to be operable as a mobile telephone or radio for long or short distance communication and transfer of information and where¬ in at least one part of the device is detachable to be worn on the persons ear. Typically the detachable part includes a speaker by which received information can be relayed to the persons ear and is provided with a receiver for receiving communication signals from the remainder of the device and/or communication emit¬ ted from the source of the telephonic or broadcast signal. In one embodiment the second, body part of the device is worn by the person or can be hand held and includes a microphone into which the person can speak to send information. In one embodiment the second part can incorporate a dial pad or voice recognition system to allow recipients of information to be selected and their telephone numbers dialled. The invention provides a portable communications device which can, in one particularly advantageous embodiment, be provided in a form for use as a mobile phone which includes a cordless detachable part which incorporates a speaker and which can be worn on the users ear. When the first part is attached to the second part it can have the appearance of and be usable as a conventional mobile phone. In one form of this embodiment of the invention the device can be used in a "hands free" mode. In one embodiment the detachment of the first part from the second, body part of the device causes the mouthpiece on the body part, including a microphone, to be more sensitive to noise. This allows the user of the device to place the second body part of the device a distance away, for example in the range of 0-1 metres, from the mouth and still be operable without the need for the conventional, costly, additional equipment to be provided. In an alternative embodiment the detachment of the first part from the second body part allows a second microphone to be operable which is more sensitive than the first microphone and allows the second part to be used remote from the first part and is especially useful when used during walking or other activities. Preferably a selection switch is provided to allow selection to be made between microphones if two or more are provided. In a further aspect of the invention the device of the inven¬ tion can be provided as an integral part of a computer wherein the first, detachable part is housed on the body of the computer and can be removed therefrom to allow the same to be moved to an in use position on the wearer and the second part of the device is housed within or on the compu- ter body . In this embodiment the first part includes a speaker therein and can be used to listen to communication signals such as telephonic or broadcast signals whether they be mobile phone signals or other telecommunication signal or, alternatively, or in addition, can be used to listen to computer generated commands and signals or games and music such as those gener¬ ated by the computer on which the device is provided. Reference herein to computers includes any type of computer such as desktop, laptop computers for use in the home or office, electronic organisers and computer games consoles. Similarly the device can also be incorporated in a similar manner in facsimile machines or other telecommunications equipment such as telephones wherein the handset is disposed of and replaced by a first part which is adapted to be worn on the ear and a second part which includes a microphone for receiving voice communication from the user of the device and which can be incorporated in the body of the device. In whichever aspect of the invention, the device preferably includes rechargeable power cells or batteries which may be automatically recharged by clipping the first part in posi¬ tion in the second body part of the device. The invention provides a communication device which can receive information and, in certain aspects, can be used to transmit information and comprises at least two parts which are operable in combination but in a physically detached manner and therefore there is no need for connection by wire or cables between the parts. Thus the device can be used as a pager, a two way pager, a mobile telephone with no hand operation required by the person who is wearing the device or can be incorporated into an electronic organiser or compu¬ ter. This is in contrast to conventional communication de¬ vices which are required to be hand held or secured to a nearby surface thereby limiting the persons movements during operation of the device. Thus the invention provides in its broadest aspect a communi¬ cations device which can be split into at least two parts, a first part which can be worn on the ear and includes an ear piece element of the device and can receive and/or transmit information to the second part of the device which can trans¬ mit information to the first part of the device and/or can include a mouthpiece or microphone and means for dialling communication numbers and can be used remote from the ear piece part.

Referring firstly to Figures 1A-1D there is shown a first part 2 of the communication device according to a first aspect of the invention. The part includes a moulded plastic main body 4 which includes a shaped portion 6 which defines a slot 8 between the portion 6 and the body 4. The slot 8 and portion 6 are shaped to allow the part to be placed and re¬ tained on a persons ear. Within the body 4 there is provided a speaker 10 for the playing of information into the persons ear and also a sound and/or light emitter to emit a sound and/or light to inform the person when a message is received by the signal receiver within the part either from another part of the device or from a point remote to the person wearing the part. The part includes control means 14 to allow the device mode to be selected to provide immediate playback of the message received or to store the message in a memory chip within the housing until the person is ready to receive the message. The controls can also include volume control and an on/off switch. Referring now to Figures 2 and 3, the part, when not in use can be worn from a chain, cord or wire 16 as shown or could be worn as a badge or carried in a pocket or handbag. In one embodiment the cable, wire or chain from which the part is suspended can be connected thereto to act as an aerial for the device for receiving communications signals. Typically the device is provided with a light or noise emit¬ ter such that upon hearing a noise or' seeing a light emitted from the device the person is made aware that a message has been received by the device. The person may then select to enter the message received into the device memory for play¬ back later or place a part of the device onto their ear as shown in Figure 3. When the person is ready they can then operate the controls for playback and/or the reception of further live messages via the speaker 10. The communication signals can be radio signals or any other form of communica¬ tion carrying signal such as telephonic or broadcast signals. A device in one aspect of the invention is illustrated in Figures 4-6. This device 18 comprises at least two parts, a body part 22 which allows, in this embodiment, the device to be worn on the wrist and a first, detachable part 22 shown in Figures 5 and 6. In the embodiment shown the body part also includes a wrist watch 24 such that when the device is in a stored position as shown in Figure 4 it operates as a conven¬ tional wrist watch. In this embodiment the body part 20 includes an transmitter whereby messages and communication signals can be transmitted to other parties and either/or both of the parts 20,22 includes a signal receiver whereby messages can be received. The detachable part 22 also includes a speaker and a shaped portion 24 whereby the part can be placed to the persons ear by means of the shaped portion 24 as shown in Figure 5 and 6 to allow the messages received by the device to be listened to via the speaker. In use the person receives an indication that a message has been received by means of a noise or light provided on the device 18. The person then opens the device to remove the first, detachable part 22 and open out the shaped portion 24 as shown in Figure 5. The part 22 is then placed on the persons ear as shown in Figure 6 and the message received can be listened to as previously described. If the signal receiv¬ er is mounted in the body part 20 the first, detachable part 22 is also provided with a receiver and the body part a transmitter to allow the first part 22 to receive the relayed signal from the body part 20. By using the detachable part 22 on the ear and the body part 20 on the wrist which includes a signal transmitter and which can also include a microphone the person can communicate with the party sending the message as illustrated in Figure 6. The detachable part is however physically remote from the body part in use and therefore the device is significantly easier to use and is also more conve¬ nient for use than conventional wire or cable connected devices. Figures 7A-7D and 8A-8C illustrate a further embodiment of the invention wherein the device 30 includes a first, detach¬ able part 34 which is illustrated as part of the device in a stored condition in Figures 7A-7D and in a detached condition in Figures 8A-8C, and a body part 32. Again the device is shown in the embodiment of a wrist watch such that when the same is in a stored position as shown in Figures 7A-7D the device operates as a conventional wrist watch. In this embo¬ diment the device operates as a mobile telephone or radio with full transmission and reception capabilities which allows the person to select a number or frequency and initi¬ ate the sending of messages. The device can include a dial pad or a voice recognition system so that the user can speak the number required into the body part 32 which includes a microphone and speak to the other party there through while listening by detaching the detachable part 34 with the spea¬ ker thereon and placing the same to their ear. Referring now to figures 9-11 there is shown a communications device 102 according to an aspect of the invention wherein the device includes a first, detachable part 104 and a sec¬ ond, body part 106. The second body part 106 includes a mouthpiece 108 incorporating a microphone and, in this embodiment, a second microphone 110, the use of which is explained in greater detail below. The body part also in¬ cludes a key pad 112 to allow communication numbers to be dialled, other controls 114 for the provision of functions such as on/off, send and redial facilities and an aerial 116 for the reception of incoming communication signals and the transmission of outgoing communication signals. The first part 104 of the device is mountable in the slotted aperture 118 of the body part 106. The first part 104 includes an ear piece 120 with a speaker and also means (not shown) for the reception of communication signals either from the second body part 106 or directly from remote sources and the commu¬ nications received are played through the ear piece speaker. The first part 104 is also provided with mounting means 122 which allow the part 104 to be worn on the users ear without the need to hold the same in position. The device 102 in the embodiment shown can be used as a one piece device as shown in Figure 9 wherein the first part 104 is provided as part of the second body part 106 and wherein the device is operable as per a conventional mobile phone which is sufficiently well known so as not to require expla¬ nation herein. Alternatively the first part 104 can be re¬ moved from the second body part 106 by sliding the same out of the aperture 118 as shown in Figure 10 to provide a device as shown in Figure 11A and 11B wherein the first part 104 is remote from the second body part 106. While the operation of the device is still as per a conventional mobile phone, the removal of the first part 104 allows the same to be worn on or placed to the users ear remote from the body part 106 as shown in Figures 12-14. In figure 12 the first part 104 is shown mounted in position on the users ear with the speaker therein adjacent the ear. In this use the second body part 106 is positioned remote from the user such as on the dashboard of a vehicle. In this use the second microphone 110 can be selected to be operable as the removal of the first part 104 exposes this microphone which is typically more sensitive and can therefore pick up the users voice without the need for the same to be placed close to the users mouth. Thus, the device can be used hands free as is also shown in Figure 14 where the second body part 106 is shown in use and placed in the users pocket and, with the second microphone 110 exposed, the device can be used even while the user is walking around or working. In Figure 13 the device is used with the first part 104 mounted on the users ear and the second body part 106 held in the users hand and in this form either of the microphones 108 or 110 can be selected to be operable. Referring now to Figures 15 and 16 there are shown two embo¬ diments of the device provided as part of a desktop computer wherein the device includes a first detachable part 202 and a second part 204 within which the first part 202 can be stored when not in use as indicated by arrow 206. In Figure 15 the second part 204 is provided in the form of a standard size 3.5 inch floppy disc drive which can be plugged into an available drive bay and connected internally to a special accessory printed circuit card that is plugged into one of the expansion slots available inside the PC. The effect created is thus for the computer to have a speaker which in normal operation emits sound from the front of the PC body but also to provide the device of the invention such that the part 204 can be ejected from the bay in the computer and the first part 202 removed to allow the same to be worn on the ear whereupon the speaker on the computer will close and the sound listened to via the speaker in the detachable part 202 in that manner. The transmission of the signal from the body part to the first part can be by any normal media such as radio signals or infra red to avoid the risk of interference with the computer electronics. In Figure 16 the same princi¬ ples apply but in the embodiment shown the part 204 is in the form of an interface card which fits within the computer and the first part 202 is mounted externally of the computer housing. Figure 17 illustrates the device of the invention provided as part of a laptop computer 210 wherein the first part 202 is housed in the body, or second part 204 in a location slot 212 therein whereupon the device operates in the same manner as described in Figures 15 and 16. In whichever embodiment the computer can be further porovided with a microphone 224 inbuilt or provided as a movable part thereof as per the embodiments shown in the Figures wherein the user can send messages using the device by speaking into the microphone whereupon the device transmitter transmits the signals to the desired recipient. Figures 18A-D and 19 illustrate the device of the invention incorporated as part of an organiser 218 which is shown to include the standard feature of a screen 220 and a keyboard 222 and, in this embodiment, also includes microphones 224 which are positioned to allow the device to be used when the organiser is closed as shown in Figures 18B-18D or in an open position as shown in Figures 18A and 19. In use, the first part 202 can be removed from the second part 204 which is provided as an integral part of the organiser 218 which includes a location slot 212 for the first part and worn on the ear as shown in Figure 19. Thus the present invention and aspects thereof provide a communications device which can be utilised in a form such as a pager for receiving information or as a two way pager or mobile telephone or radio or as part of a computer to allow received signals to be listened to and, in several embodi¬ ments , signals to be transmitted. The ability to detach a part for listening to the message received and wearing the same on the ear or placing to the same to the ear while sending information by talking into another part which is worn or in the vicinity of the user allows the device to be used hands free. Furthermore, the device can provide the same facilities as much larger and relatively bulky devices.
