Abstract
A shield for use with an aerial of a mobile phone comprising a jacket 1, a permeable reticulate metal element 2 placed within the wall of said jacket. Inside the jacket are either a plurality of elastic clamp elements 11 or a neck is formed (Fig. 7) so that the jacket and metal element may be secured onto the aerial. Another aspect is that a plurality of jewels (Fig. 4 and 5) may cover the outside of the jacket, high density jewels blocking the em waves. This device therefore goes towards reducing the effects of em waves produced by aerials and therefore protects the user from their harmful effects.
Description
2355854 Electromagnetic Wave Absorber and Damper of Cellular Phone
Field of the Invention
The present invention relates to an electromagnetic wave of cellular phone, and more specifically to an electromagnetic wave absorber and damper which may reduce the damage of electromagnetic wave to the head of people when people use cellular phone.
Backaround of the Invention
Personal communication age is coming by high technology developing. Cellular phone is so popular in the world and gives us a convenient communication, but during transmittin and receivin- the electromagnetic wave also has some bad ID g effects because of transmitter too closing to head of people. Because the electromagnetic wave may bring some dam ages even cancer to the brain of people, some doctors advise people don't using cellular phone too much or too long during communicating. However, in this modem society and busy booming world, some people have to use cellular phone connecting with the world. Therefore, that becomes the bigger issue for reducing the electromagnetic wave damage to the head of people.
By using the professional skills in jewel business, developing a necklace or wrist lace with a permeability metal wire 61 going through jewel 6 is carried out (as shown in Fig. 11). The necklace or the wrist lace may be taken as a decorator; also, the necklace or the wrist lace may hang up on the antenna of cellular phone when people want to use cellular phone. By the interference of metal wire 61, the electromagnetic wave influence on people may be reduced. In addition, the necklace and wrist lace can be designed in different style for religious people. For example, Fig. 12 is a decorator lace designed for Catholics, and also, necklace may be designed as Buddha lace for Buddiiist. Not only those designs are not appropriate but also the interference of metal wire doesn't head to a proper direction. That will affect the communication quality.
0 Summary-of the Invention
The primary object of the present invention is to provide an electromagnetic I wave absorber and damper of cellular phone. In the partial surface of a jacket, a plurality of permeability metal elements is installed. The jacket may directly cover on cellular phone antenna for reducing the electromagnetic wave influence effect to people but not affecting communication.
Another object of the present invention is to provide an electromagnetic wave absorber and damper of cellular phone. A plurality of jewel covering on the outside jacket provides a further prevention in electromagnetic wave by the high density of jewel.
Another object of the present invention is to provide an electromagnetic wave absorber and damper of cellular phone. The permeability metal element may be installed and covered inside the wall of jacket when the jacket is molded.
Another object of the present invention is to provide an electromagnetic wave absorber and damper of cellular phone. Inside the jacket, the first preset space and the second preset space are formed for covering the antenna of cellular phone and compressing tightly the permeability metal element respectively.
Therefore, basing on absorbing of the metal element of permeability reticulate C metal plate or permeability metal plate and damping of the high density of jewel, electromagnetic wave damage may be reduced when the jacket covers on the I cellular phone antenna and the metal element faces to the head of people.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

Description of the Preferred Embodiments
Referring to Fig. 1, Fig. 2 and Fig. 3), the electromagnetic wave absorber and damper of cellular phone comprises a rubber made jacket 1, a permeability metal element 2, and a plurality of elastic clamp element 11. Metal element 2 which can be a reticulate metal plate or a metal plate 2A is'embedded inside the wall of jacket I about one third of circumference. Also, elastic clamp I I which can be cylinder shape (as shown in Fig. 3)) or flange shape is extended to interior surface ofjacket 1.
The internal diameter of circle formed by the end of plurality of cylinder shape or flange shape elastic clamp element 11 is smaller than the external diameter of conventional cellular phone antenna. In the internal wall of jacket 1, a narrow neck 12 is formed in the middle (as shown in Fig. 7). On the both opposite ends of interior space 10, they are wider than the middle portion. The internal diameter of narrow neck 12 is a little smaller than the external diameter of ordinary cellular phone antenna 5. Therefore, jacket I may cover antenna 5 firmly by elastic clamp element I I or marrow neck 12 (as shown in Fig. 6). When people are using cellular phone, metal element 2 is in the side near the head of people. The electromagnetic wave interference effect of metal element 2 may reduce the electromagnetic wave intensity to the brain of people. The rest of uncovered portions may still transmit and receive signal without affected. Furthermore, the upside end of jacket I can be sealed or opened.
Moreover, jacket I is covered by a plurality of jewel (as shown in Fig. 4 and 3) 5 Fig. 5). The plurality of jewel can be engaged to form a cover by nylon line, or 3 directly attach on jacket I by some stick technic. What kind of jewel is used will deeply affects the damping, effect due to the different density and hardness of jewel. Therefore, low density/ hardness jewel 3) and high density/ hardness jewel 4 are engaged together. The surface of high density/ hardness jewel 4 spread is same position covered by metal element 2, and the low density/ hardness jewel 33 covers the rest surface of jacket 1. The high density/ hardness jewel is marked (For example by color, label and so on) to make users sure high density/ hardness jewel 4 facing to transmitter whenjacket 1 is covered on the cellular phone antenna. So, metal element 2 and high density/ hardness jewel 4 are put between head and antenna for protecting head from the damage of electromagnetic wave. Also, those jewels can decorate cellular phone for creating, unique style, Another embodiment of the present invention is shown in Fig. 8 to Fig. 10. Jacket I may be made with rubber material, and separator 13 is also formed as same time as producing process of jacket I for creating two differ ent size spaces, first internal space 102 and second internal space 10'). A plurality of clamp element I I is set in proper level inside first internal space 102 with same gradient in circular arranged (as shown in Fig. 10). Therefore, each elastic clamp element 11 jointly forms a clamp space 10 1 which is smaller than the external diameter of antenna 5, so jacket I may firmly covers and stands on antenna 5 with a plurality of elastic clamp element 11. Second internal space 10') is in rectangle shape and has same radian corresponding to the surface of jacket 1. Both ends, corresponding to the center of jacket I of second internal space 10'), form a absorbing and damping angle 6 which may be set in 60' to 180'; and the best absorbing and damping effect will locate between 90 " and 120'. Because the internal diameter of second internal space 103 is smaller than the external diameter of metal element 2, second internal space 103) may firmly cover and fix metal element 2 directly.
Moreover, jewel 6, corresponding set outside jacket I of metal element 2, may decorate the cellular phone, and also efficiently absorb and damp electromagnetic wave which radiates to the head of people.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only, and that numerous changes in the detailed construction and the combination and arrangement of parts may be restored to without departing from the spirit and scope of the invention as hereinafter claimed.
