Abstract
The utility model discloses a radiation-proof earphone. The utility model is composed of a plug, a microphone, a loudspeaker, connecting conducting wires and a hollow flexible pipe, wherein, the plug is connected with the microphone by one conducting wire, the loudspeaker is connected with the plug by one conducting wire, the loudspeaker is arranged in a small sealed compartment, one end of the small compartment, which is provided with holes, is connected with the hollow flexible pipe in a sealing manner, and the other end of the hollow flexible pipe is connected with a hollow earplug. As a result, the electromagnetic radiation of a mobile phone, etc., can be effectively prevented from doing harm to people. The earphone has the advantages of simple structure and technology, easy implementation, no increase of industrial cost, and important value of practical application.
Description
The utility model relates to a kind of Headphone device, especially a kind of mobile communication Headphone device.
Existing mobile communication is lead with earphone and connects, and loud speaker places auricle or is close near the auricle, although its form is varied, the loud speaker that plain conductor links places in the auricle or near being close to, then is common feature.This just characteristics have been brought the infringement of some healths to the user.Not long ago, Britain scientist's a test shows, with the conversation of regular handset earphone, human body head can be subjected to more directly with the more radiation of mobile phone communication, and reason is the head that the plain conductor of earphone imports electromagnetic wave the people.Subsequently, China scientific and technical personnel have also done coherent detection, and its conclusion is not quite similar with the former, think that earphone can prevent electromagnetic radiation to a certain extent, then are undisputable facts but also have electromagnetic radiation with earphone.
The purpose of this utility model provides a kind of ear speaker device that can reduce even eliminate radiation.
The technical solution of the utility model is achieved in that the utility model is on the basis of existing handset earphone structure, improved, lead with original loud speaker, shorten to the position of microphone, with the hollow container sealing of loud speaker, stay an aperture on the chamber wall then, be tightly connected with aperture with one section hollow tube (warp equates with the small-bore in the pipe) with corresponding size, at the shell of the other end lug plug of flexible pipe, the air in airtight container, flexible pipe, the earplug shell is linked.Like this, when the loud speaker sounding, drive the air column vibrations in flexible pipe and the earplug shell, people then can clearly hear sound, because air is the non-conductor of electromagnetism, thereby this kind earphone does not have electromagnetic radiation, thereby has solved the problems referred to above.
The utility model will effectively prevent the harm of electromagnetic radiation such as mobile phone to the people, and structure and technology are all simple, and easily row can't increase production cost, has important practical value.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing 1 is first example structure schematic diagram of the utility model;
Accompanying drawing 2 is second example structure formula intention of the utility model.
Shown in accompanying drawing 1, earphone is by plug 1, microphone 2, loud speaker 3, connect lead 4 and hollow tube 5 compositions, plug 1 is connected with lead 4 with microphone 2 one ends, be connected with lead 4 between loud speaker 3 one ends and the plug 1, loud speaker 3 leads 4 are shortened near microphone 2, with corresponding big small container 7 sealings of loud speaker 3 usefulness, certain space is all left in the front and back of loud speaker, play the audio amplifier effect, have on the chamber wall about tubule and diameter 4MM, the hollow tube 5 about the 2MM of aperture links, about hollow tube 5 long 10cm, the air of hollow tube and earplug shell 6 is interconnected, and like this, an anti-radiating earphone promptly constitutes.
Among the embodiment as shown in Figure 2, also loud speaker 3 and microphone 2 can be shortened simultaneously, on the one hand the flexible pipe that extends and link to each other with loud speaker 3; Hollow tube and extend to earplug shell 6 about 10CM places, the microphone 9 of the other end connection hollow of hollow tube also is tightly connected on microphone 2 simultaneously.
Claims (2)
