Description: DESCRIPTION The market of cellular phones and of means of telecommunication in general, operating by radio waves with corresponding electromagnetic fields is expanding greatly on our planet and it looks like it will continue. These transmission systems interconnect both through the use of radio bridge systems on earth and connection to a satellite causing, in any case, problems of electrosmog with as yet unquantifiable potential risks to the health of citizens. Certainly, the attention given to such problems is very high and any finding which reduces, even in small quantities, the emission of waves which are harmful to the health of individuals must be deemed of great interest to the community. Said problem of electromagnetic pollution is definitely amplified when wireless electrical devices are close to the head, particularly for prolonged periods where even modest powers can, after only a few minutes, cause the cerebral temperature to increase. In such situations, it is clear that the risk to health is greater and greater in relation to the power used and to the distance from the brain at which the device in question is held. The great discomfort that one experiences if one makes a long call by cellular phone is well known; after a few minutes one feels a considerable heating of the temporal bone and/or the auricle and, in some cases, one also feels pains inside the auricle or types of migraine. What will the evaluation of these discomforts and devices be in the future in relation to human health, today we cannot tell: many studies are being carried out to assess precisely the risks of such devices, now an integral part of everyday life. State of the Art In order to try to reduce the damage done by heating the brain and whatever else may emerge in time as a consequence of the use of wireless communication devices, hand-free cellular phone systems have been introduced into the market, even if they have not had great success because of the lack of privacy. The solution of the auricle which keeps the brain away from the transmission device and at the same time permits communication to be carried out in total privacy has, however, had great success. The Auricle Communication systems (in brief ACSys) for wireless communication devices, such as cellular phones, normally consist of: a plug, a connection cord, a microphone and one or two earpieces. An ACS, therefore, connects to a device such as a cellular phone by means of a plug, allowing a person to listen with headphones and to talk into a microphone positioned on average two-thirds of the way up the length of the cable, thus allowing a cellular phone to be used without having to use one's hands and without putting the phone near to the skull. Recent studies have found , however, that the cord transmits a quantity of electromagnetic emissions to the head (indeed there are some who claim that the quantity is three times greater than when the mobile phone is held close to the ear) and thus, it is necessary to evaluate any alternative solution which reduces such effects with particular attention. Moreover, the position itself of the electric cord which ends up with the earpiece inside the auricle, gets so close to the brain that any finding aiming to separate such an electric terminal from the brain will be a new finding and that goes towards solving an extremely important health problem. Air Call System ACS The designed system, known as Air Call System (ACS) aims to bring the audio communication of normal electrical communication devices to an auricle by means of just an empty tube connected internally in various ways for the main and secondary function of the equipment . It is already known that , in order to listen to a low audiodynamic power through headphones, without particular qualitative requirements a simple hollow tube will suffice. Examples of this are the headphones normally used by some airlines which work only according to this principle or the stethoscope normally used by a doctor to auscultate our body. Object of the present finding is the application to wireless electric communication systems of a range of solutions which allows them to be used without exposing the user to electrical emissions or harmful fields in general leaving them at a safe distance from the user, this is possible by using a hollow tube for the interconnection to the loudspeaker of the auricle thus keeping a safe distance. A headset made according to ACS system as opposed to a normal ACSys is shown in fig.l. Elements of such a solution are: 1 electric connection plug 2 multipolar connection cord 3 microphone 4 microloudspeaker (of the auricular type) 5 interconnection casing 6 metallic shield adapted to isolate the electromagnetic field emitted by the microloudspeaker and by the microphone 7 hollow tube 8 hollow auricle 9 protective rubber bulb 10 ground wire, connected internally to the phone with the plate 11 12 ground discharge plate. 13 optional connecting/disconnecting system Along the hollow connection tube (7) a lug connection/disconnection system (12) can be forseen, in order to connect an optional extension to further separate the phone, or to connect the phone to other devices - e.g. a motorcycle helmet with headphones provided internally also using a hollow tube (fig.3) . The ACSys system is completely new and different from any auricle currently on the market which can be used for cellular phones or similar devices. Indeed, at a given distance from the cellular phone, we will provide a suitable interconnection case (5) with many functions: connector between an electric loudspeaker and air connection, microphone holder, electric shield, etc. The loudspeaker function is carried out by a microloudspeaker (4) that preferably can be of more or less similar dimensions to those of the microloudspeaker normally present in normal auricles. Such a microloudspeaker is inserted in a container of a suitable shape, adapted to convey the sound into the tube (7) and maximise the yield of the acoustic dynamics. In the proximity of the loudspeaker (4), or in another preferable location adapted to avoid resonance, optionally also outside the interconnection case (5), a suitable microphone will be arranged (3) . The loudspeaker 4 and the microphone 3 can also be arranged in a suitable metallic container or shield (6) adapted to block the electromagnetic waves emitted by the two electric devices, carried out in the form of a light metallic capsule placed inside the case (5) and connected to the ground through the ground cable (10), in turn connected to the ground plate (11). Alternatively the same case (5) can optionally be realised in a suitable material (e.g. light metal) in order to function both as a container for the devices and as an electric shield. The hollow plastic tube (7) will extend from the case (5) and will transfer adequately the acoustic waves sent by the microloudspeaker (4) to the auricle (8) . Said tube (7) can also be realised with variable internal section, and in any geometric form, in order to optimise the characteristics of the finding. Moreover, also envisaged is the presence of a return of electric ground to the cellular phone (10) also discharged to the ground through the hands of the user, via the plate (11) located on the cellular phone or elsewhere. The system thus realised will be entirely electrically isolated from the head of the user, both because the microphone and the electric microloudspeaker are far from the head of the user, and because the same components are electrically shielded. Other substantially similar solutions and which form an integral part of the present finding and which can be realised through example are: Solution B: In such a solution the microphone is present directly on the cellular phone and is used with the common technique of the "hand-free phone" . The microloudspeaker is also inside the cellular phone and is connected through an appropriate connecter, with the acoustic connection tube. The acoustic tube can alternatively be linked to the microloudspeaker of the cellular phone by means of a suction or joint system. Solution C: In such a solution a hypothesis for a solution for connection to wireless mobiles was made. In such a case a central unit (connected to the mobile by radio or by infrared rays or other similar techniques) will be envisaged that will contain the microphone and the loudspeaker. On such a central unit connections will be foreseen allowing connection to the acoustic guide auricle, whilst the microphone will be installed on said central unit, and will be used holding the central unit the necessary distance from the user. The central unit will also be able to have amplification functions in order to optimise the acoustic yield and will also be able to have other command functions towards the main device; Solution D: In this solution (fig.2) it is envisaged that there be a rigid auricular holder with the characteristics of design 1 with the peculiarity that the rigid part (13) is realised in internally hollow material and optionally adjustable to optimize the distance from the telescope user (14) is articulated (14bis) with the central part empty thus allowing the passage of sound. The end part is appropriately rounded to facilitate use; it is possible to have a link to attach the auricle to the ear with greater ease. In the telescopic part are the auricle (3) and the microphone (4) . Solution E: In this solution (fig. 3) the realisation of a crash helmet (15) with internal headphones (16) in which the sound is also transmitted through a hollow tube is foreseen. The microphone (17) of the mobile can be linked to the helmet through another hollow tube (air-air system, as in solution D) , or can consist in a traditional electric microphone fitted inside the helmet and connected to the mobile through an electric plug (mixed air-electric system) . Solution F: In such a case, there will be an acoustic guide auricle of the type previously indicated, with the end part (18), used for connection with the auricle, realised preferably in a soft material with the aim of allowing for. all types of of auricle present in the marketplace so as to render the system universal even for auricles already in use.
