Abstract
The utility model relates to a wireless earphone for a mobile phone, which comprises an earphone and a signal connector, wherein, the signal connector is installed on a phone, and the earphone is connected with the signal connector in a wireless mode. When the utility model is used, the earphone is used for answering the phone, and the mobile phone is not required to be attached to an ear. As a result, the utility model has the advantages of avoidance of the radiation of a mobile phone to brains and convenient and flexible use.
Description
The utility model relates to a kind of earphone, particularly a kind of wireless headset that is used for mobile phone.
Mobile phone is commonly called as the birth of mobile phone, has changed people's life, become people work the life in an indispensable part.But along with the universal use of mobile phone, the relevant expert recognizes that gradually mobile phone also is not perfect in every way.The electromagnetic radiation that produces in its use may cause brain tumor and other the nervous system disease, particularly aligns the children that are in growth and development stage, excessively uses mobile phone might produce even more serious consequence.Therefore the expert reminds the least possible mobile phone of using of cellie, also tries not during use direct subsides of mobile phone is placed on ear or head.Wired earphone formula mobile phone becomes the communication tool of mobile phone market coideal, it has temporarily solved the problem of human brain away from the mobile phone radiation source, but the line between wired earphone and mobile phone according to the principle of point discharge, can or can not more cause that brain is still waiting further textual criticism in the concentrated area with radiation.And the line between earphone and mobile phone brings inconvenience to the user.
The purpose of this utility model provides a kind of in earphone and telephone booth realization wireless connections, can avoid the wireless earphone of mobile telephone of mobile phone radiation.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of wireless earphone of mobile telephone comprises earphone and the signal connector that is contained on the phone, adopts wireless connections between earphone and the signal connector.
Owing to adopt above-mentioned structure, during use, utilize the earphone receiving phone, mobile phone need not to paste and is placed on the ear, avoids mobile phone to the brain radiation, uses more convenient, flexible.
