Abstract
The utility model relates to a mobile phone casing capable of reducing the influence of electromagnetic wave radiation, which is composed of a shell and an antenna. The utility model is characterized in that earphone holes and microphone holes are respectively arranged at the upper side part and the bottom side part of the shell, and the upper side part and the bottom side part are far from the antenna. According to the theory of spherical surface electromagnetic wave propagation, the energy flow density of electromagnetic waves is in inverse proportion to the square of the distance from the antenna, therefore, the utility model can enable the electromagnetic wave energy absorbed by a user's head to be obviously decreased compared with the existing mobile phones, and the adverse effect of electromagnetic wave radiation on the human body is reduced, which is favorable to protecting users' health.
Description
The utility model relates to the shell of a kind of mobile phone in the radio telephone communication field.
Mobile phone claims mobile phone again, and is well-known, because being talked about the hole and sending the words hole to be in respectively from antenna very near housing front and bottom side on its shell makes it when conversation is used, user's head is also very near from antenna.And apart from expert's test analysis, the stronger electromagnetic wave of mobile phone aerial radiation causes harmful effect to people's head easily, cause that headache, weak, dizziness etc. are uncomfortable, even can cause that human body produces more serious neurasthenia, cause vegetative nerve disorder and disease of cardiovascular system, the health of grievous injury human body.Universal day by day along with mobile phone, this problem also more and more causes people's attention and attention.
The purpose of this utility model is intended to the shell mechanism of existing mobile phone machine is improved, so that a kind of mobile phone shell that alleviates electromagenetic wave radiation to the human influence to be provided.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is the schematic perspective view of a kind of concrete structure of the utility model;
Fig. 2 is that the A of Fig. 1 is to view
Fig. 3 is the B-B profile of Fig. 2.
Referring to Fig. 1 to Fig. 3, solution of the present utility model is as follows. It still has housing 1 and is contained in shell Antenna 2 on the body 1 offers respectively and being talked about that housing 1 inside is connected on housing 1 top and bottom side Hole 12 is talked about with sending in hole 11, and its feature part structurally is, is talked about hole 11 and send words hole 12 Be opened in respectively upper lateral part and the bottom side of the housing 1 far away apart from antenna 2.
Has the utility model of said structure when packing the internal machine core that matches into, as long as with being subjected on the movement Words device and transmitter are designed to aim at respectively to be talked about hole 11 and is sent words hole 12, and the user uses in conversation like this The time, only need the side 13 of the housing 1 that head proximity distance antenna 2 is far away, just can realize smoothly conversation. According to the physical electromagnetic theory of wave propagation, the sphere electromagnetic wave in communication process, its energy-flux density with from the distance of antenna From square be inversely proportional to, namely littler apart from antenna electromagnetic wave energy-flux density at a distance, thereby can be so that the user The energy Ratios existing mobile phone machine of head electromagnetic wave absorption obviously reduces, thereby alleviates Electromagnetic Wave Radiation on Human Harmful effect, be conducive to protect user's health.
The utility model is applicable to the mobile phone of various different models and function.Its employing will make vast mobile phone user feel more relieved and use this modern communication instrument audaciously, exempt and use future trouble and the trouble and worry that mobile phone brought.
Claims (1)
1, a kind of mobile phone shell that alleviates the electromagenetic wave radiation influence, have housing and the antenna that is contained on the housing, offer being talked about the hole and sending the words hole of being connected with enclosure interior respectively on housing top and bottom side, it is characterized in that, talked about the hole and send the words hole to be opened in the upper lateral part and the bottom side of the housing far away respectively apart from antenna.
