Detailed Description of Preferred Embodiments With reference to Fig. 1 there is shown a swimmers head worn entertainment and communication device 10 comprising, in this instance, a first ear assembly 11 connected in opposed relationship to a second ear assembly 12 by means of interconnect device 13. The interconnect device 13 comprises a first semi-rigid support 14 connected in opposed relationship to a second semi-rigid support 15 by an adjustable length concertina unit 16 (shown in detail in the insert of Fig. 1). The semi-rigid supports 13, 15 can take the form of elongate rods made from a plastics material. The adjustable length concertina unit 16 can take the form of a tubular plastics material having hingedly interconnected ferrules adapted to collapse one against the other about hinges 18. In this instance first ear assembly 11 is constructed in the same manner as second ear assembly 12 and comprises transducer 19 supported on lower limb 20 from a free end 21 of the respective semi-rigid supports 14, 15. Each ear assembly 11, 12 further includes an upper limb 22 integrally attached to free end 21 and opposed to lower limb 20 so as to define an ear containing space 23 therebetween. Both lower limb 20 and upper limb 22 are curved so as to follow at least part of the contour of a human ear as best seen in Fig. 2. They are sufficiently curved that they substantially encircle the ear save for an entry region 24 which presents a sufficient aperture to allow the ear assemblies 11, 12 to be engaged about an ear 25 by a sliding approach of aperture 24 approaching from the rear of the ear. In this instance the limbs 20, 22 are made from the same plastics material as the semi-rigid supports 14, 15 and are integrally moulded therewith. The upper and/or lower limb can include an adjustable length concertina unit. In this instance the upper limb 22 is formed of two segments joined by concertina unit 26 thereby allowing adjustment for the ear containing space 23 according to the requirements of the user. The entertainment and communication device 10 further includes an equipment module 27 threaded onto or formed with second semi-rigid support 15 and a similar module 29 threaded onto or formed with first semi-rigid support 14 as shown. In this instance the equipment module 27 contains an AM and FM radio receiver whose audio out jack is connected by cable 28 to transducer 19, which transducer is shaped to fit snugly into the entry to the auditory canal of a user as best seen in Fig. 2. Equipment module 27 may include an on/off switch and a volume control (not shown). In this instance the semi-rigid supports 14, 15, the lower limbs 20 and the adjustable length concertina unit 16 are hollow and permit cable 28 to be threaded therethrough. The rigidity of the semi-rigid supports 14, 15 and the concertina unit 16 is selected so that when the ear assemblies 11, 12 are mounted about the ears of a user in opposed relationship they apply a gentle pressure to the head of the user so as to assist retention in place of the entertainment and communication device. In this instance the second equipment module 29 can contain batteries connected by a cable (not shown) to the radio within module 27. In use a user turns the radio unit on and selects a radio station and listening volume satisfactory for that user. The user then places the entertainment and communication device about their head as above described and so as to achieve the orientation illustrated in Fig. 2. The user may then swim laps of a pool of the like whilst listening to the radio, the arrangement being such that relatively little drag is added and, such drag that there is, does not dislodge the entertainment and communication device from the head of the wearer. Turning to Fig. 3. a second embodiment of the swimmers head worn entertainment and communication device 30 illustrated comprising, in this instance, the device 10 of Fig. 1 into which has been installed a radio receiver 31 adapted to be in communication with a local transmitter 32. The transmitter 32 is in communication with a head set 33 having ear braces 34 and microphone 35 and connector cable 36 adapted to allow local radio communication with transmitter 32 which, in turn, is in communication with radio receiver 31. With this arrangement a coach or like person can wear headset 33 and have mounted elsewhere on their person the local transmitter 32 and, with this arrangement communicate with device 10 whilst a swimmer is doing laps in a pool. Alternatively, the unit can be tuned to the frequency of local transmitter 32 for reception of broadcasts from that unit instead. The arrangement can be such that normally the swimmer will have their unit 31 tuned to a radio station, a transmission from the headset 33 as and when it occurs. In an alternative embodiment one of either the first ear assembly 11 or second ear assembly 12 can be omitted, but leaving a sufficient stub end at the free end 21 for the purpose of ensuring that it can provide the necessary reactive pressure against the head of a user, equal and opposite to the pressure being applied to the other side of the head of the user by the remaining ear assembly. In a further alternative embodiment of the invention interconnect device 13 can comprise only the cabling necessary to provide electrical power and communication between the ear assemblies and the radio or like communications device in the equipment module 27. With reference to the arrangement shown in Fig. 3 input jack 37 to local transmitter 32 can receive audio input from a walkman, CD player or other source of audio input for subsequent communication to the radio receiver 31 of the swimmers head worn entertainment and communication device 10. With reference to Fig. 4 a further embodiment of the invention is illustrated wherein free end 21 of semi rigid support 14 in this instance comprises s stub 38 of a dimension sufficient to permit a user to adjust pressure applied to a users head located between the stub 38 and the ear assembly 12. Fig. 5 illustrates a further embodiment of the invention in this instance comprising a single ear assembly 112 including a transducer 119 in communication with an equipment module 127 housing a radio receiver (not shown). Component parts are identified by numerals as for earlier embodiments, except that a prefix numeral 1 has been added. The present invention may be used for a number of on-land and in- water aquatic activities. The above describes only some embodiments of the present invention and modifications, obvious to those skilled in the art, can be made thereto without departing from the scope and spirit of the present invention.
