Description:
FIELD OF THE INVENTION 
       [0001]    The present invention generally relates to acoustic devices, and in particular to an acoustic wave conductor for mitigation of harmful radiation inherent in mobile devices. 
       BACKGROUND OF THE INVENTION 
       [0002]    Based on new findings, the World Health Organization classifies cell phones as a potential cancer risk, much like exhaust from gasoline-powered vehicles and lead. For many people, it&#39;s just not practical or realistic to avoid cell phones altogether. And it may not be necessary, if one takes precautions for reducing exposure. The standard used by federal regulators may not be the best measure of safety, nor is it the best way to help concerned consumers reduce their exposure. 
         [0003]    Moving a cell phone, or other mobile device, even an inch from the body can greatly reduce radiation exposure. Signal strength falls off as the square of the distance to the source. This means that if one doubles the distance to the source, which is from the cell phone to one&#39;s head, the signal strength would be four times less, since two squared is four. If one triples the distance, the signal strength would be nine times less, and so on. 
         [0004]    In US Pat. App. No. 20110170730A1, “Safe In-Ear Earphones,” Zhu discloses a safe in-ear earphone for radiation protection, comprises earplug heads, sound cavities, acoustic wave transmission channels, a main body, a conductor and a plug. The channels are set between the sound cavities and loudspeakers. The acoustic wave concentrated orifices are between the loudspeakers and the acoustic wave transmission channel assemblies of the loudspeakers. The acoustic wave concentrated orifices and the acoustic wave transmission channels are sealed to form sealed small boxes in the main body. The shape of acoustic wave concentrated orifices is inversely conical. The acoustic wave is transmitted to the two acoustic wave channels via the acoustic wave concentrated orifices and then is provided to the ears plugged by two earplugs to listen. The safe in-ear earphone is used for high frequency magnetic field and intense radiation communication device such as mobile phone. 
         [0005]    The Federal Communications Commission (FCC) recommendations stipulate keeping a cellphone up to 2.5 cm away from the users head. The acoustic channel of the present invention provides for a separation of 5-6 cm, i.e., 2 times 2, or 4 times as safe.

Apple iPhone 4—Important Product Information Guide:
 
For optimal mobile device performance and to be sure that human exposure to
 
         [0006]    RF energy does not exceed the FCC, IC, and European Union guidelines, always follow these instructions and precautions: When on a call using the built-in audio receiver in iPhone, hold iPhone with the dock connector pointed down toward your shoulder to increase separation from the antenna. When using iPhone near your body for voice calls or for wireless data transmission over a cellular network, keep iPhone at least 15 mm (5/8 inch) away from the body, and only use carrying cases , belt clips, or holders that do not have metal parts and that maintain at least 15 mm (⅝″) separation between iPhone and the body. 
         [0007]    Thus, it would be advantageous to provide an acoustic channel to be attached to a mobile device speaker that is simple, efficient, economical and effective, thereby enabling the user to hear telephone conversations, but keep the device at a safe distance from the head and all his vital tissues. 
       SUMMARY OF THE INVENTION 
       [0008]    Accordingly, it is a principal object of the present invention to provide an acoustic wave conductor to be attached to a mobile device speaker, thus enabling the user to hear telephone conversations, but keep the device at a safe distance from the head and all the vital tissues of the user. 
         [0009]    It is another principal object of the present invention to provide an acoustic wave conductor to be attached to a mobile device speaker that is simple, efficient, economical and effective 
         [0010]    It is one other principal object of the present invention to safely generate sound away from the head, like the secret service type plastic tube with air-headphone. 
         [0011]    It is a further principal object of the present invention to enable the acoustic wave conductor to be attached with a “clip-on” attachment that can be adjustable depending on phone thickness. 
         [0012]    An acoustic wave conductor assembly is provided for mitigation of harmful radiation inherent in a mobile device belonging to a user.

       DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0024]    The principles and operation of a method and an apparatus according to the present invention may be better understood with reference to the drawings and the accompanying description, it being understood that these drawings are given for illustrative purposes only and are not meant to be limiting. 
         [0025]      FIG. 1  is a schematic illustration of the acoustic conductor for mitigation of harmful radiation inherent in mobile devices shown inserted in the ear of a user, constructed according to the principles of the present invention. The human ear is composed of three major sections: the outer ear  130 , the middle ear  140  and the inner ear  150 . Each section has a specific function in the hearing process. The path for conduction of acoustic sound waves to inner ear  150  begins from outer ear  130 , through middle ear  140  and then conduction to inner ear  150  through bone conduction. Sound enters outer ear  130 , which has two parts, the Pinna  131 , or visible portion of the ear, and the external auditory canal  132 . The acoustic wave conductor  120  of the present invention is shown inserted into the external auditory ear canal  132  of the user&#39;s ear. By such “hand-in-glove” insertion, ambient noise is excluded from being heard by the user, noise that would otherwise interfere with the voice of a remote caller or called party. 
         [0026]    Earplug devices are meant to be worn fully inserted into one&#39;s ear. One needs to get the squishy tip to form a tight seal with all of the walls of the ear canal—“like a cork in a wine bottle.” Without that proper seal, the transference of sound will suffer, especially the low frequencies, and too much outside noise will creep in. 
         [0027]    Middle ear  140  consists of three tiny bones, or ossicles, that are suspended in an air-filled space. They connect the eardrum to inner ear  150 , which is embedded in the skull. The ossicles function as a mechanical lever system that delivers sound from ear canal  132  to inner ear  150 . Noise does not affect middle ear  140 , unless there is an impact sound or pressure so great that it dislodges or fractures the ossicles. 
         [0028]    In inner ear  150 , the cochlea  151  is susceptible to damage from continued exposure to high-level noise. Cochlea  151  is a fluid-filled hydraulic system driven by the piston action of the last ossicle. The vibrating motion of the ossicle produces a wave motion in a membrane that runs the full length of cochlea  151 . If the vibrations are fast, high-frequency sounds, the membrane has its greatest motion at the base of the cochlea near the vibrating ossicle. If the vibrations are slow, low-frequency sounds, the maximum membrane motion occurs at the tip of  151 . 
         [0029]    The primary function of Pinna  131  is to aid in sound source localization. The various ridges in Pinna  131  filter the signal at frequencies over 4000 Hz according to the direction of the sound. The resulting spectral variations allow the brain to determine the elevation of a sound and localize sounds in reference to our position. 
         [0030]    Ear external auxiliary canal  132  can be modeled as a tube approximately 2.8 cm long that is closed at one end by the tympanic membrane. Unlike a rigid tube that has a sharp spike in amplitude at the resonant frequency, ear canal  132  has a wide resonance peak from approximately 2-5 kHz. Ear canal  132  is not rigid, nor is it a straight tube. Therefore damping is introduced, thereby altering the resonant frequency. Thus, ear canal  132  can raise the Sound Pressure Level (SPL) of the ear by up to 15 dB, which will amplify the incoming acoustic signal. 
         [0031]      FIG. 2  is a schematic illustration of the acoustic wave conductor  220  for mitigation of harmful radiation inherent in mobile devices shown attached to a mobile phone  210 , which may be any mobile listening and or speaking device, such as iPod, 
         [0032]    Android, or wireless land phone handset, constructed according to the principles of the present invention. An acoustic wave conductor connector  215  is used to connect between acoustic wave conductor  220  and mobile phone  210 . One form of exemplary connector is described with reference to  FIG. 4  below. However, any satisfactory means of connection may be used, such as a magnet or simple spring clip. Acoustic wave conductor  220  can be plastic, metal or a composite and can preferably be “telescopic,” i.e., extendable and retractable by the sliding of overlapping sections. The smaller end of acoustic wave conductor  220  is near mobile phone  210 , to facilitate connection. 
         [0033]      FIG. 3  is a photographic illustration of the acoustic wave conductor  320  for mitigation of harmful radiation inherent in mobile devices, shown attached to a mobile device  310 , constructed according to the principles of the present invention. 
         [0034]      FIG. 4  shows photographic illustrations of exemplary means of connection between the acoustic conductor and the user&#39;s mobile device, constructed according to the principles of the present invention. In a preferred embodiment the acoustic wave conductor  420  is adapted to have a threaded end for securely being orthogonally screwed into a Spring India™ cage clip nut  415 . The free end of the acoustic wave conductor  421  is designed to be inserted into the ear of a user. The clip portion of exemplary cage clip nut  415  is designed for secure insertion of the users mobile phone  410 . Acoustic wave conductor  420  is shown extending through cage clip nut  415  into secure physical connection with the speaker of the user&#39;s mobile phone  410 . 
         [0035]    Optionally, acoustic wave conductor  420  could be connected to extend in the plane of the mobile phone and/or could “jack-knife” fold back against acoustic wave conductor  420 , along with the threaded portion of cage clip nut  415 , for stowing away more compactly. 
         [0036]      FIG. 5  is a schematic illustration of the acoustic conductor for mitigation of harmful radiation inherent in mobile devices provided with an extended case  512  housing a storage compartment  513  for the acoustic wave conductor  520  in mobile phone  510 , constructed according to the principles of the present invention. An insertion slot  514  is shown on mobile phone  510 , which mates with a key extension Not shown) on acoustic wave conductor  520  for guided connection. 
         [0037]      FIG. 6  is a schematic illustration of an exemplary magnetic means of connection between the acoustic wave conductor and the user&#39;s mobile phone  610 , or other type of mobile device, constructed according to the principles of the present invention. As illustrated with reference to  FIG. 2 , the acoustiv c wave conductor may be a straight tube  620 , or it may be telescopic as shown in front view  621  and side view  622 . The attachment means may be provided by implementation of a mobile phone magnetic attachment  616  and an acoustic wave conductor magnetic attachment  626 . 
         [0038]      FIG. 7  is a schematic sideview illustration of exemplary attachment means  730  between the acoustic conductor  722  and the user&#39;s mobile device  710 , constructed according to the principles of the present invention. Attachment means  730  is represented schematically as a hash-marked rounded feature circumscribing the rectangular intersection of the two elements  730 ,  722 . 
         [0039]      FIG. 8  is a schematic rearview illustration of exemplary attachment means  830  between the acoustic conductor and the user&#39;s mobile device  810 , constructed according to the principles of the present invention.
