Abstract
The invention discloses a loudspeaker free from electromagnetic radiation, which consists of a front cover, a shielding mesh enclosure, a vibration system, a magnetic circuit system, a shielding base and a rear cover, wherein the shielding mesh enclosure and the shielding base are made of metal materials, electromagnetic wave generated by a magnetic circuit system can be restricted in a space surrounded by the shielding mesh enclosure and the shielding base and cannot be transferred out of the space; the shielding mesh enclosure and the shielding base cannot restrict sound transmission generated by the vibration system; and sound is sequentially transmitted out of the loudspeaker from the shielding mesh enclosure and the front cover with holes in an air vibration mode. The electromagnetic wave generated by the magnetic circuit system can be effectively shielded by the design adopted by the loudspeaker free from electromagnetic radiation, and a user is free from the hurt of electromagnetic radiation.
Description
Technical field
The present invention relates to loud speaker, especially a kind of loud speaker that does not have electromagnetic radiation.
Background technology
At present, the effect of prenatal culture has obtained more and more people's approval, and people generally believe that the women has important impact on the education that fetus carries out to its intelligence development and personality growth afterwards at period of gestation.Based on this kind theory, a lot of women are chosen in and antenatally carry out prenatal culture by various modes.
Although a lot of pregnant woman have admitted this conception of species of prenatal culture, but carry out this problem of prenatal culture how and do not have a clearly understanding, some pregnant woman adopts the method for oral account to come to carry out one-side communication with the fetus of oneself, and some employing is carried out prenatal culture in the indoor mode of stereo set music playing of utilizing.Though adopt the method for oral account can realize certain prenatal culture effect, increased pregnant woman's burden in the middle of invisible; And more obvious in the mode drawback of indoor music playing, the one, lack convenience, the pregnant woman must stay in around the stereo set, the 2nd, lack validity, because fetus is in the uterus, and the environment source of sound is across thick stomach wall and amniotic fluid, and fetus does not almost receive the voice signal that the environment source of sound sends.
Some Antenatal training apparatus occur in the market and solved above-mentioned two kinds of problems that method is brought, but these prenatal culture equipment are not taked any safeguard procedures for electromagnetic radiation, can in pregnant woman's use procedure, bring electromagnetic radiation hazards, not only not reach the antenatal training belt purpose and cause harmful effect to fetus on the contrary.Scientific experiment proves, electromagnetic radiation is very large to the influence degree difference of human body, and particularly pregnant woman and fetus more easily are affected.Specifically, 1-3 month is embryonic period, embryonic phase, is subject to strong electromagnetic radiation and might causes miscarriage, also may cause fetal limb damaged or lopsided; Electromagnetic radiation may damage central nervous system, caused infant intelligence low for fetus is shaped the phase in 4-5 month; 6-10 month is the fetus growth stage, and its major consequences then is immunologic hypofunction, and a little less than the physique, resistance is poor after the birth.So intrinsically safe Antenatal training instrument must be not produce any radiation and magnetic field when guaranteeing the prenatal culture effect for the pregnant woman, this just at present prenatal culture equipment generally be short of.
In order to improve the fail safe of prenatal culture equipment, based on the scientific theory of electromagnetic shielding, designed this kind loud speaker involved in the present invention.Can be used for prenatal culture, also can be used for other and need the sound source device of electromagnetic radiation shielding.
Summary of the invention
The present invention overcomes the deficiencies in the prior art exactly, and a kind of loud speaker of brand-new design is provided, and the audible segment of this equipment will adopt ELECTROMAGNETIC RADIATION SHIELDING to process, and allow the user avoid the injury of electromagnetic radiation.
In order to address the above problem, the present invention has adopted following technical scheme: a kind of loud speaker of electromagnetic-radiation-free is comprised of protecgulum, shielding new cover, vibrational system, magnetic circuit system, shielding base, bonnet.
Among the present invention, the shielding new cover of electromagnetic-radiation-free loud speaker and shielding base are made of metal material, in the space that the electromagnetic wave that can allow magnetic circuit system produce is limited in being surrounded by shielding new cover and shielding base, and can't be delivered to space outside this.
Among the present invention, the sound transmission that shielding new cover and shielding base can the constrained vibration system produce, sound propagates into the loud speaker outside by shielding new cover and porose protecgulum successively by the form of air vibration.
Advantage of the present invention: the present invention is with low cost, and effect is remarkable, can effectively shield the electromagnetic wave that magnetic circuit system produces in the sonification system.
Description of drawings
Accompanying drawing 1 is the structure principle chart of a kind of electromagnetic-radiation-free loud speaker of the present invention.
Embodiment
The present invention will be further explained below in conjunction with accompanying drawing: as shown in Figure 1, the electromagnetic-radiation-free loud speaker is comprised of protecgulum (101), shielding new cover (102), vibrational system (103), magnetic circuit system (104), shielding base (105), bonnet (106).
The shielding new cover of electromagnetic-radiation-free loud speaker (102) and shielding base (105) are made of metal material, the electromagnetic wave that can allow magnetic circuit system (104) produce is limited in by shielding new cover (102) and shields in the space that base (105) surrounds, and can't be delivered to the space outside this.
The sound transmission that the shielding new cover of electromagnetic-radiation-free loud speaker (102) and shielding base can constrained vibration system (103) produce, sound propagates into the loud speaker outside by shielding new cover (102) and porose protecgulum (101) successively by the form of air vibration.
The signal of electromagnetic-radiation-free loud speaker is inputted by outer line (107).
The electromagnetic-radiation-free loud speaker can be worn at it the pregnant woman, and audio signal is changed into transmission sound to fetus, and fetus only can receive voice signal, and can not be subject to any electromagnetic radiation.
Electromagnetic radiation shielding design of the present invention allows prenatal culture become safer.The present invention can also be used for other and need the sound source device of electromagnetic radiation shielding.
