Abstract
The utility model relates to an earphone for mobile telephones, handsets, walkie talkies and radios. The utility model can eliminate the harm and the influence of electromagnetic waves of a common earphone for brains and chests. According to the physical phenomenon that sound waves can propagate in pipelines, sound generated by electromagnetism passes through a flexible hollow guide pipe with a minor diameter, and only sound waves propagate into ears, and thereby, a brain is completely disengaged from the source of electromagnetic waves. Sound is still softer, and auditory sensation is not damaged. The earphone has the advantages of simple structure, low cost, and convenient placement and use. The style of the utility model is similar to the style of a common earphone, and the utility model can be manufactured into a compact and delicate earphone. The utility model can also be directly matched with an existing earphone. The utility model can completely relieve people's misgivings about health when people use mobile phones and earphones.
Description
The utility model relates to mobile phone and mobile phone and walkie talkie and wireless a kind of earphone.
The electromagenetic wave radiation that present mobile phone and walkie talkie, wireless earphone are produced, harm in various degree affects user's brain health.From relevant report and data-searching and market survey: also do not have a kind ofly can eliminate electromagenetic wave radiation and no electromagnetic earphone.The product of present mobile phone protection electromagenetic wave radiation has Japan to produce " anti-electromagnetic wave radiation sheet " and Sino-Japan joint " HT300 electromagnetic wave membrane screen " is the making of HT300 shielding material, pastes body pronunciation place.The function of saying: stop, the reflected radiation ripple.And Japan produces " An Tailang is paper tinsel at random " subsides body back side and Korea S produces pronunciation place of " paper tinsel at random " subsides body, is rare element, metal is made.The function of saying: transfer, filtering noxious electric wave.The defective of this series products is: partly protection effect is arranged; Body and antenna there is not the integral protection function; Mostly be shielding again, rare element, metal and active and have certain radioactivity material and make have the possibility of new pollutant sources.
The purpose of this utility model provides a kind of earphone that does not have electromagenetic wave radiation.
The purpose of this utility model is achieved in that the physical phenomenon of utilizing sound wave can pass through pipe transmmision, object vibration, settle one can detain and be attached to first spherical enclosed poly-sound head [1] of former earphone at one of hollow tubing conductor [2], the tubular cavity earphone [3] of UNICOM is settled in the other end; Hollow tubing conductor length is 100 centimetres-5 centimetres, 1 centimetre-0.01 centimetre of internal diameter.
This earphone is only sound wave to be propagated in the ear by hollow tubing conductor, so there is not electromagnetic generation at all, sound is softer, does not damage the sense of hearing.Because of hollow tubing conductor has safe length, body distance, angle can arbitrarily be adjusted, so brain is away from emission source.Body and antenna there is the integral protection function.Increase volume as need and can also in poly-sound head or cavity earphone, settle vibrating membrane.This earphone also can directly make with former earphone be holistic integrated, also use the primary circuit socket, also can with the direct matching used supporting formula of existing earphone.Hollow tubing conductor can be convenient to fold, place with the strong path material of soft plasticity.Pattern is similar to common headphones, can small and exquisite exquisiteness make.This earphone structure is simple, cost is low, it is convenient just to use, and can use personnel's brain of earphone, chest thoroughly to break away from electromagnetic wave emission source.
Fig. 1 does not have the basic view of electromagenetic wave radiation earphone according to the supporting formula that the utility model proposes.
Fig. 2 is the cutaway view of structure shown in Figure 1.
The concrete structure of utility model is provided by following examples and accompanying drawing, describes in detail according to concrete structure and the principle situation that the utility model proposes.
Fig. 1 is described to be that former earphone combines by the closed poly-sound head of hemisphere [1], and sound wave enters hollow tubing conductor [2], spreads out of from tubular cavity earphone [3].
Fig. 2 is that horn-like in the poly-sound head [1] of Fig. 1 structure shown in analysing and observe advances sound mouth [4] and the sound mouth [5] of hollow tubing conductor [2] in cavity earphone [3].
Claims (2)
1, a kind of no electromagenetic wave radiation earphone, this earphone is on the sonorific basis of electromagnetism, it is characterized in that the enclosed poly-sound head of hemisphere [1] enters tubular cavity earphone [3] to former body and earphone sound wave by soft hollow conduit [2].
2, no electromagenetic wave radiation earphone according to claim 1 is characterized in that 100 centimetres-5 centimetres of hollow tubing conductor length, and internal diameter is 1 centimetre-0.01 centimetre.
