Abstract
The utility model discloses a radiation proof earphone, which belongs to the technical field of the electrical apparatus product. The radiation proof earphone is characterized in that the radiation proof earphone comprises a plug and a first earplug connected through a guide line, the first earplug is connected with a hollow hard tube in which upper soft film and lower soft film are put, and a second earplug is arranged at the top end of the hollow hard tube. Regarding the radiation proof earphone provided by the utility model, the sound sent out after being electroacoustically converted in the inner circuit of the first earplug can be firstly transmitted to the second earplug through the hollow hard tube, then transmitted to the human ear, during the process, the transmission performed in the hollow hard tube is air transmission, human head is far away from the high-frequency electromagnetic wave and the high-frequency induced current of the first earplug, and thereby the radiation generated by the earphone to human head can be avoided.
Description
Technical field
The utility model belongs to the electric equipment products technical field, relates in particular to a kind of anti-radiating earphone.
Background technology
Be accompanied by the development of society, people's living standard is more and more higher, and the application of Wireless Telecom Equipment such as mobile phone, Personal Handyphone System and walkman, electronic products such as MP3, MP4 more and more widely.Under the occasion, the said goods need use earphone mostly.Current earphone all is by lead tone currents to be passed to earplug, carries out the electroacoustic conversion by the earplug internal circuit again.Like this, the frequency electromagnetic waves, the high frequency induction current that produce during work such as mobile phone, Personal Handyphone System, walkman, MP3, MP4 can produce radiation to the head part by earphone, thereby health is caused certain influence.
The utility model content
Problem to be solved in the utility model just provides and a kind ofly can not produce the anti-radiating earphone of radiation to the head part.
For addressing the above problem, the technical solution adopted in the utility model is: comprise the plug and first earplug that are connected by lead, described first earplug is connected with the hollow hard tube that is built-in with upper and lower mantle, and the top of hollow hard tube is provided with second earplug.
Its additional technical feature is: the upper and lower mantle in the described hollow hard tube is connected by the call wire of tightening;
The described hollow hard tube and first earplug are connected as a single entity;
The described hollow hard tube and first earplug flexibly connect, and the tail end of hollow hard tube is provided with the adapter sleeve that is complementary with first earplug.
Anti-radiating earphone provided by the utility model, first earplug is connected with the hollow hard tube that is built-in with upper and lower mantle, and the top of hollow hard tube is provided with second earplug.Such first earplug internal circuit carries out the sound that sends after the electroacoustic conversion, earlier propagate into second earplug by hollow hard tube, propagate ear by second earplug again to the people, in hollow hard tube, be air borne therebetween, the head part is away from the frequency electromagnetic waves and the high frequency induction current of first earplug, thereby avoided earphone that the head part is produced radiation.And the upper and lower mantle in the hollow hard tube is connected by the call wire of tightening, and except air borne, also has mechanical inoculation between then upper and lower mantle, and it is better that sound matter is propagated.As required, hollow hard tube can be connected as a single entity with first earplug, also can flexibly connect.When flexibly connecting, the adapter sleeve that can be complementary at the tail end setting and first earplug of hollow hard tube is enclosed within adapter sleeve on first earplug during use, and is when not using, that adapter sleeve is by taking off on first earplug, very easy to use.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model anti-radiating earphone;
Fig. 2 is the another kind of structural representation of anti-radiating earphone.
Embodiment
Be described in further details below in conjunction with the concrete structure and the use principle of accompanying drawing the utility model anti-radiating earphone.
As shown in Figure 1, 2, the utility model anti-radiating earphone comprises the plug 2 and first earplug 3 that is connected by lead 1, first earplug 3 is connected with hollow hard tube 4, be provided with mantle 5, following mantle 6 in the hollow hard tube 4, last mantle 5, following mantle 6 are connected by the call wire of tightening 7, and the top of hollow hard tube 4 is provided with second earplug 8.The hollow hard tube 4 and first earplug 3 can be connected as a single entity as shown in Figure 1, also can be as shown in Figure 2, and the adapter sleeve 9 in that the tail end setting and first earplug 3 of hollow hard tube 4 is complementary flexibly connects the hollow hard tube 4 and first earplug 3.
During use, plug 2 is inserted on mobile phone, Personal Handyphone System, walkman, MP3, the MP4 etc., and tone currents passes to first earplug 3 by lead 1, carries out the electroacoustic conversion by first earplug, 3 internal circuits again, the sound that sends, earlier propagate into second earplug 8, propagate by second earplug 8 again and give people's ear by hollow hard tube 4, therebetween hollow hard tube 4 under the effect of mantle 5, time mantle 6, call wire 7, existing air borne, also have mechanical inoculation, it is fine that sound matter is propagated, and human body is not had radiation.
Claims (4)
