AN UNDERWATER AUDIO SYSTEM

Abstract: An unterwater audio system including a frame having at least one speaker mounted thereon and at least one upwardly extending arm member. The arm members are arranged to slide under the strap of a diver's mask in use and be held in place between the strap and the diver's head. The speakers mounted on the frame are arranged to be located adjacent a diver's ear when the arm members are in place under the strap of the diver's mask.

Description: TITLE "AN UNDERWATER AUDIO SYSTEM" BRIEF DESCRIPTION OF THE INVENTION The present invention relates to an underwater audio system. FIELD OF THE INVENTION It is known for divers to desire the use of headphones whilst underwater. These may be for the purpose of receiving instructions or communicating with other divers or personnel on the surface. They may also be desired for other purposes such as listening to music while diving. A known type of headset for divers includes speakers built into the sides of a standard diving hood. This type of arrangement where the speakers are held next to the diver's ear is necessary as standard ear-pieces that are inserted in the ear would be forced into the ear by water pressure causing damage to the ear. This known type of arrangement however has disadvantages in the time taken to put the headset on and to remove the headset. This may be important in situations where it is required to quickly remove the headset for safety reasons. For example, it may be necessary to quickly remove the headset if the headset cables become entangled. The present invention overcomes at least in part some of the aforementioned disadvantages of previous underwater audio systems. SUMMARY OF THE INVENTION In accordance with one aspect of the present invention there is provided an underwater audio system characterised by including a frame having at least one water proof speaker mounted thereon and having at least one arm member arranged to slide under a strap of a diver's mask and be held in place between the strap and the diver's head. DESCRIPTION OF THE DRAWINGS The present invention will now be described, by way of example, with reference to the accompanying drawings, in which. Figure 1 is a perspective view of a headset of an underwater audio system in accordance with the present invention; Figure 2 is a perspective view of a waterproof housing of an underwater audio system in accordance with the present invention; Figure 3 is a perspective view of a volume control means of the waterproof housing of Figure 2, and Figure 4 is a perspective view of the headset of Figure 1 including an audio input support member. DESCRIPTION OF THE INVENTION Referring to Figures 1 and 2, there is shown an underwater audio system 10 including a frame 12, speakers 14 and a housing 16. The frame 12 includes first and second side members 18 and 20 The first and second side members 18 and 20 are arranged generally parallel to each other, in use, at a distance such that they may rest either side of a diver's head. The first side member 18 includes a first transversely extending member 22 at a first end thereof The second side member 20 includes a second transversely extending member 24 at a first end thereof. The frame 12 further includes a rear member 26. The rear member 26 is connected between second ends of the first and second side members 18 and 20 by first and second hinges 28 and 30 respectively The first and second hinges 28 and 30 allow the first and second side members ^ 18 and 20 to fold back so that they are generally parallel to the rear member 26 when not in use. Further the rear member 26 is curved to generally follow the shape of the rear of the diver's head. The first and second side members 18 and 20 each include a respective arm member 32 and 34. The arm members 32 and 34 extend generally perpendicular to the respective side members 18 or 20 from a point intermediate the first and second ends of the side members 18 and 20. Each arm member 32 and 34 is arranged to be inserted under a strap of a diver's mask, adjacent to and behind the diver's ear. Preferably, each arm member 32 and 34 is twisted slightly at upper ends thereof to sit flat against the diver's head and be held securely between the strap of the diver's mask and the diver's head. The first and second transversely extending members 22 and 24 each include an opening 50 at an upper end thereof. Each opening 50 is arranged to receive a speaker 14. The first and second transversely extending members 22 and 24 and speakers 14 are arranged such that when the arm members 32 and 34 are engaged with the strap of the diver ' s mask, the speakers 14 are held adjacent the diver's ears. The speakers 14, once inserted in the openings 50, are waterproofed by any convenient means. Cables 38 are provided to connect each speaker 14 to a portable audio device (not shown). The cables 38 are preferably secured to an outer surface of the corresponding transversely extending member 22 and 24 and side member 18 and 20. A waterproof housing 16 is provided to house the portable audio device. The housing 16 includes a receptacle portion 42 and a removable cover 40. The removable cover 40 includes a seal member 44 and is arranged to be fastened to the receptacle portion 42 by a plurality of clamp means 46 The clamp means 46 may be any suitable clamping arrangement to produce a watertight seal between the receptacle portion 42 and the removable cover 40 In another embodiment, one of the clamp means 46 may be replaced by hinge The housing 16 also includes a first aperture (not shown) to receive the cables 38 The first aperture 48 is arranged to be sealed around the cables 38 to maintain the water proofing of the housing 16 The housing 16 further includes an attachment means (not shown) on a lower surface arranged for attachment to a portion of a diver's gear For example, for connection to a diver's vest or belt Figures 2 and 3 show a volume control means 52 for the underwater audio system 10 The volume control means 52 includes a rotatable member 54 arranged to be received in a second aperture 56 in the housing 16 The second aperture 56 includes a second seal member to prevent water from entering the housing 16 through the second aperture 56 The rotatable member 54 is connected to a variable resistor 58 included in the cables 38 Rotation of the rotatable member 54 varies me resistance in the cables 38 and hence the volume at the speakers 14 Figure 4 shows an alternate embodiment of a frame 12 of an underwater audio system 10 wherein an audio input support member 60 is provided The audio input support member 60 is arranged to be connected at a first end thereof to either the first or second side member 18 or 20 The audio input support member 60 is curved such that a second end thereof is positioned adjacent the diver's mouth An audio input device 62 is mounted on the second end of the audio input support member In use, when the dive_ has completed putting on his necessary equipment, the portable audio device is placed in the waterproof housing 16. The cover 40 is then secured to the housing 16 via clamping means 46. The housing 16 may then be secured to the diver's vest by the attachment means. The frame 12 is then placed around the diver's neck and the arm members 32 and 34 are slid under the strap of the diver's mask such that the speakers 14 are positioned alongside the diver's ears. The frame 12 may then be simply removed, if required, by pulling down on the frame 12 to disengage it from the strap of the mask. Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
