Problems solved by technology

[0005] In order to overcome the inconvenience of carrying the above-mentioned patch cord earphones and still damage the user's heart or kidneys, when an electromagnetic wave shielding layer is added to the side of the transparent mobile phone cover facing the observation window and / or keyboard, the transparency will be significantly reduced and the user's accurate keystrokes will be affected. And / or watch the shortcoming and deficiency of display screen, the present invention provides a kind of listening back type anti-radiation mobile phone case, this anti-radiation mobile phone case is easy to carry and use, can tightly and effectively shield the harm of electromagnetic radiation to the user, can send and receive normally again receive signal

Abstract

A back-hearing type anti-radiation handset jacket includes an antenna cap, a handset jacket, a phone receiver, a phone transmitter a signal connecting wire and a power supply plug characterized by that a magnetic wave shielding layer is set up at one side of the antenna cap the transmitter and part signal line and / or shield layer are enclosed fixedly between the jacket and the protection layer, the plug and part signal lines are left outside the outder side of thej acket, and the side shielding is made of transparent material. In using, the view window and the key board are towards the transparent side and the side with the shielding layer is towards the body.

Description

Technical field: [0001] The invention relates to the technical field of electromagnetic compatibility, in particular to a listening-back type anti-radiation mobile phone cover. Background technique: [0002] Mobile phone handsets are referred to as mobile phones, which emit electromagnetic waves in all directions during calls. Excessive or long-term electromagnetic radiation will affect the health of users. The usual mobile phone is to install the receiver, display, keyboard, and microphone on the mobile phone. Close to the inner side of the human body, when the user is talking, the receiver hole of the inner casing must be attached to the ear for two-way communication. At the same time, electromagnetic waves continuously radiate the user's head through the antenna and the inner casing. brain parts, thereby causing harm to the health of users. [0003] At present, the use of plug-in earphones is one of the effective ways to reduce the damage of electromagnetic radiation to ...
