技术领域  Technical field
本发明涉及一种手持移动电话机，更确切地说是涉及一种具有防 电磁辐射功效、 保护人体健康的手持移动电话机 （俗称大哥大或手 机） 。 发明背景  The present invention relates to a hand-held mobile phone, and more particularly, to a hand-held mobile phone (commonly known as a big brother or a mobile phone) which has the function of preventing electromagnetic radiation and protecting human health. Background of the invention
随着无线通讯的迅猛发展，移动电话使越来越多的人亲身体验到 高科技信息时代给人类的进步所带来的便捷和喜悦， 与此同时，这种 高科技产品移动电话却在其它方面削减了人自身的力量， 比如健康。 人体内的神经信号是以低频传送的，移动电话工作时的电磁波对神经 信号的干扰就可能对中枢神经系统产生危害，尤其移动电话用于接收 和传递微波的天线是直接置于电话使用者头部的一侧，是靠近人体对 微波辐射最为敏感的大脑和眼睛。在中国， 正在使用的移动电话的辐 射强度超过国家相关卫生标准几十倍， 在美国和英国等一些西方国 家， 政府卫生机构及专家已提醒公众， 为避免损害， 尽量少使用移动 电话， 每次使用的时间近可能简短。  With the rapid development of wireless communication, more and more people are experiencing the convenience and joy brought by the high-tech information era to human progress. At the same time, this high-tech mobile phone Aspects reduce one's own strength, such as health. The neural signals in the human body are transmitted at low frequencies. The interference of electromagnetic signals on mobile phones during work may cause harm to the central nervous system. Especially the antenna used by mobile phones to receive and transmit microwaves is placed directly on the head of the phone user. One side of the body is near the human brain and eyes, which are most sensitive to microwave radiation. In China, the radiation intensity of mobile phones in use exceeds the relevant national health standards by dozens of times. In some western countries such as the United States and the United Kingdom, government health agencies and experts have reminded the public to use mobile phones as little as possible to avoid damage. The time used may be short.
大量调查、研究和试验的结论示出， 每天使用手持移动电话一小 时以上的人常会出现头痛、面部和头部刺痛、 耳后发热、 头晕和疲倦 等症状。这是由于传统的做法是将手持移动电话机的发射功率放大级 及其天线设计在手持移动电话机的上部， 用户在打开天线使用手机 时，天线恰位于耳后，而距离天线 3- 5厘米的位置处也正是高频电磁 射线最为强烈的地方， 高频电磁射线近距离直接作用于人脑， 因而引 起了上述症状，使用短天线的 G S M手持移动电话时所引起的反应还 会更大 发明内容 Numerous surveys, studies, and trials have concluded that people who use a handheld mobile phone for more than an hour a day often experience symptoms such as headaches, facial and head irritation, fever behind the ears, dizziness, and fatigue. This is because the traditional method is to design the transmitting power amplifier stage of the handheld mobile phone and its antenna on the upper part of the handheld mobile phone. When the user opens the antenna and uses the mobile phone, the antenna is located behind the ear, and the distance is 3-5 cm from the antenna. The high-frequency electromagnetic radiation is the strongest place at high-frequency electromagnetic radiation. The high-frequency electromagnetic radiation directly affects the human brain in a short distance, which causes the above symptoms. The response caused by the short-antenna GSM handheld mobile phone is still Will be more inventive
本发明的目的是设计一种防电磁辐射的手持移动电话机，可避免 用户在使用手机时受其功放发射级及天线高频电磁辐射线的危害，保 护人体健康。  The purpose of the present invention is to design a handheld mobile phone that is resistant to electromagnetic radiation, which can avoid users from being harmed by the power amplifier emission level and antenna high-frequency electromagnetic radiation when using a mobile phone, and protect human health.
本发明一种防电磁辐射的手持移动电话机，包括手持移动电话机 主体和天线， 手持移动电话机主体至少包括有送话器、受话器和功率 放大发射级， 其特征在于：  The present invention provides a handheld mobile phone that is resistant to electromagnetic radiation, and includes a main body of a handheld mobile phone and an antenna. The main body of the handheld mobile phone includes at least a microphone, a receiver, and a power amplifier transmitting stage. The characteristics are:
所述的功率放大发射级及与之连接的天线位于手持移动电话机 主体的受话器一侧，该功率放大发射级及与之连接的天线与所述送话 器间的垂直向距离大于其与受话器间的垂直向距离。  The power amplifying transmitting stage and the antenna connected to the power amplifying transmitting stage and the antenna connected to the power amplifying transmitting stage and the connected antenna are greater than the distance between the power amplifying transmitting stage and the connected antenna and the microphone. The vertical distance between the two.
根据上述技术方案，还包括有柔性金属丝网，包覆在所述的手持 移动电话机主体外并与手持移动电话机的地端连接。  According to the above technical solution, it further comprises a flexible metal wire mesh, which is wrapped outside the main body of the hand-held mobile phone and connected to the ground of the hand-held mobile phone.
所述的柔性金属丝网上设有幵口，位于所述手持移动电话机主体 下方的天线处， 开口边缘的金属丝网卡掣在天线座内。  The flexible metal screen is provided with a slit, which is located at the antenna below the main body of the handheld mobile phone, and the metal screen at the edge of the opening is locked in the antenna base.
由于高频电磁源信号的辐射线强度与其辐射距离的平方成反 比，将原本使用时向上打开的天线改为向下打开， 并将原功率放大发 射级随天线一起下移至电话机的受话器侧，使天线离开用户耳部的距 离增加而辐射强度衰减，人脑受电磁射线的影响大为减少， 从而有效 保护了人体健康。经对三种手机型号的四次测试，使用美国辐射危险 计 RAHAM4A, 将手机拨通后， 用 RANAM4A的探头分别置于原手 机和使用本发明手机的听筒上方 3cm处部位测试， 测试结果显示， 现有移动电话的辐射强度最高为 1900 W/cm2， 最低为 200 w W/cm2， 平均为 1233 W/cm2， 而使用本发明的手机的辐射强度最高为 80 μ W/cm2， 最低为 6 w W/cm2， 平均为 55 μ W/cm2， 前后的衰减倍数平均达 到 25倍， 衰减 dB数平均为 13。 使用本发明技术方案的效果是显尔 易见， 非常显著的。 Because the intensity of the radiation of the high-frequency electromagnetic source signal is inversely proportional to the square of its radiation distance, the antenna that was originally opened up when used is changed to open downwards, and the original power amplification transmitting stage is moved down with the antenna to the receiver side of the phone As a result, the distance between the antenna and the user's ear is increased and the radiation intensity is attenuated. The human brain is greatly reduced by the influence of electromagnetic radiation, thereby effectively protecting human health. After four tests on three mobile phone models, using the American radiation hazard meter RAHAM4A, after dialing the mobile phone, the probe of RANAM4A was placed on the original mobile phone and using the mobile phone of the present invention 3cm above the handset, and the test showed that The maximum radiation intensity of the existing mobile phone is 1900 W / cm 2 , the minimum is 200 w W / cm 2 , and the average is 1233 W / cm 2. The maximum radiation intensity of the mobile phone using the present invention is 80 μ. W / cm 2 , the minimum is 6 w W / cm 2 , the average is 55 μ W / cm 2 , the attenuation multiples before and after reach an average of 25 times, and the average attenuation dB is 13. The effect of using the technical solution of the present invention is obvious and very significant.
此外， 由于还在电话机主体外套置接地的柔性金属丝网屏蔽罩， 更进一步减弱了高频电磁射线对人脑的伤害。  In addition, since a flexible metal wire mesh shield is grounded on the outer casing of the telephone body, the damage to human brain by high frequency electromagnetic radiation is further reduced.
再者， 本发明还具有结构简单、 便于实施且防辐射收效大的特 点， 打破了传统的天线使用、 安装习惯， 虽只是将天线向上打开使用 改为向下打开使用，但却有效地解决了原天线置于耳后所带来的损害 人体健康的大问题。 附图简要说明  Furthermore, the present invention also has the characteristics of simple structure, easy implementation, and large radiation protection effect. It breaks the traditional antenna usage and installation habits. Although it is only used to open the antenna upwards and downwards, it effectively solves the problem. The major problem of damaging human health caused by the original antenna placed behind the ear. Brief description of the drawings

下面结合附图对本发明进行详细阐述。  The present invention is described in detail below with reference to the drawings.
参见图 1、 图 2， 防电磁辐射的手持移动电话机将天线及功率发 射放大级设置在机体的下方且位于受话器侧，至少可以有两种实施结 构， 即分别如图 1、 图 2中所示的天线 1 1、 21与受话器 12、 22互为 左、 右侧， 送话器 13、 23仍位于机体的上方， 显示器 14、 24及按键 15、 25则分别位于机身的中间部位。 Referring to FIG. 1 and FIG. 2, the electromagnetic radiation-proof handheld mobile phone is provided with an antenna and a power transmitting amplification stage below the body and on the receiver side. There can be at least two implementations. The antennas 1 and 21 and the receivers 12 and 22 shown in Figs. 1 and 2 are respectively left and right, and the microphones 13 and 23 are still located above the body. The displays 14, 24, and buttons 15 , 25 are located in the middle of the fuselage.
用户使用手机时向下打开天线 1 1、 21， 天线距离耳部接近手机 机体的长度， 高频电磁辐射的强度因距离增加而衰减， 有效地减弱了 人脑受电磁辐射线危害的影响。  When the user uses the mobile phone, open the antenna 1 1 and 21 downwards. The distance between the antenna and the ear is close to the length of the body of the mobile phone. The intensity of the high-frequency electromagnetic radiation is attenuated due to the increase in distance, which effectively reduces the human brain's influence from the electromagnetic radiation.
参见图 3、 图 4， 以图 1实施例为例， 手持移动电话机开盖后分 成机体 10及机盖 20， 机体 10内设置了全部手机电路， 机盖 20内则 设置有送话器的耳机 28及受话器的驻极体话筒 27， 耳机 28及话筒 27上分别设有弹性接触片 281、 271。 为了使机体 10与机盖 20对合 时能将耳机 28及话筒 27上的弹性接触片 281、 271与位于机体 10 内的相应电路连接，而在机体 10内对应设置了话筒接点 17及耳机接 点 18。  Referring to FIG. 3 and FIG. 4, taking the embodiment of FIG. 1 as an example, after opening the cover of the handheld mobile phone, it is divided into a body 10 and a cover 20. All the mobile phone circuits are set in the body 10, and a microphone The earphone 28 and the electret microphone 27 of the receiver. The earphone 28 and the microphone 27 are provided with elastic contact pieces 281 and 271, respectively. In order to connect the body 10 and the cover 20 to the elastic contact pieces 281 and 271 on the earphone 28 and the microphone 27 and the corresponding circuits located in the body 10, a microphone contact 17 and a headphone contact are provided in the body 10 correspondingly. 18.
由图 3及图 4可见，机体 10内的功放发射级电路芯片 16随天线 一起下移， 该功放发射级电路芯片 16及与之连接的天线 1 1、 21与作 为送话器的耳机 28间在纵向上的距离大于其与作为受话器的驻极体 话筒 27间在纵向上的距离。  It can be seen from FIG. 3 and FIG. 4 that the power transmitting circuit chip 16 of the power amplifier in the body 10 moves down with the antenna. The power transmitting circuit chip 16 of the power amplifier and the antennas 11 and 21 connected to the power transmitting circuit chip 16 and the headset 28 as a microphone The distance in the longitudinal direction is greater than the distance in the longitudinal direction from the electret microphone 27 as a receiver.
本发明的防电磁辐射的手持移动电话机与目前普遍使用的手持 移动电话手机的结构完全相同，其一种实施结构是将功放发射电路芯 片 16及天线 1 1移至手机下方的受话器 12—侧， 用信号线将功放发 射电路芯片 16与仍位于手机上部的原电路连接即可。 其另一种实施 结构是仅将原手持移动电话机倒置 (天线向下：)， 并将送、 受话器的位 置上、 下对换， 使功放发射级及天线与受话器接近， 只需改动与送、 受话器间的连线， 此时的显示器与按键的位置也可上、 下互换。无论 那种实施方案均具有结构简单、 便于实施、 防辐射功效显著的优点。 参见图 5， 为进一步改进防辐射性能， 还可在手机机身外套设一 柔性金属丝网罩 30， 柔性金属丝网罩 30上于天线位置处设有开口 31， 一方面供天线拉出， 也方便金属丝网罩与天线地或与手机地连 接。加设金属丝网罩不会影响正常使用手机，但却可屏蔽一部分高频 电磁射线。 The structure of the handheld mobile phone for preventing electromagnetic radiation of the present invention is completely the same as that of the currently used handheld mobile phone handsets. One implementation structure is to move the power amplifier transmitting circuit chip 16 and the antenna 11 to the receiver 12-side below the handset. Just connect the power amplifier transmitting circuit chip 16 with the original circuit still located on the upper part of the mobile phone with a signal line. Another implementation structure is to just turn the original hand-held mobile phone upside down (antenna down :), and change the position of the transmitter and receiver up and down, so that the power amplifier transmitting stage and antenna are close to the receiver. The connection between the receiver and the receiver, the position of the display and the buttons can also be switched up and down. No matter which embodiment has the advantages of simple structure, easy implementation, and significant radiation protection effect. Referring to FIG. 5, in order to further improve the radiation protection performance, a flexible metal mesh cover 30 may be provided on the outer casing of the mobile phone body. The flexible metal mesh cover 30 is provided with an opening 31 at the antenna position. On the one hand, the antenna is pulled out. It is also convenient to connect the metal mesh cover with the antenna ground or the mobile phone ground. Adding a wire mesh cover will not affect the normal use of the mobile phone, but it can shield some high-frequency electromagnetic radiation.
