Abstract
The invention discloses electromagnetic-radiation free antenatal training equipment with volume and audio control functions, comprising a player, a volume and audio controller, a belt, electromagnetic-radiation free speakers, an audio connection wire and headsets. The audio signal of the player is transmitted to the volume and audio controller by the audio connection wire; after being treated in the volume and audio controller, the audio signal is output to two groups of electromagnetic-radiation free speakers and headsets; the electromagnetic-radiation free speakers are sued for transforming the electrical signal into sound for the antenatal training of the infant; and by processing the sound by the volume and audio controller, the sound and frequency of the sound signal are controlled in the range of being safe to the development of the infant. Due to the design of the electromagnetic-radiation free speakers, the electromagnetic waves generated by a magnetic circuit system can be shielded effectively so that the infant and the pregnant woman are protected against the damage of the electromagnetic radiation. The electromagnetic-radiation free antenatal training equipment guarantees the effectiveness and the safety of antenatal training.
Description
Technical field
The present invention relates to prenatal culture equipment, the especially a kind of electromagnetic-radiation-free prenatal culture equipment that can control the output of volume audio frequency.
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 products often do not pass through the design of science, do not meet the maximization principle of prenatal culture effect, and the leeway that on portable and ease for use, all improves a lot.
And these prenatal culture equipment all do not have volume and the audio frequency of sounding are limited.Studies show that the sound that volume is excessive or audio frequency is too high will damage the hearing of fetus.So need to process the sound of prenatal culture, in rational scope, enable voice can not damage the healthy of fetus and grow volume and audio frequency control.
In addition, these prenatal culture equipment are not taked any safeguard procedures for electromagnetic radiation, can bring electromagnetic radiation hazards in pregnant woman's use procedure, not only do not reach the antenatal training belt purpose and cause harmful effect to fetus on the contrary.Scientific experiment proves that electromagnetic radiation is very large to the influence degree difference of human body, and particularly pregnant woman and fetus are easier is 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, resistibility 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.
For security, validity, portability and the ease for use that improves prenatal culture equipment, based on the scientific theory of prenatal culture, designed this kind antenatal training belt involved in the present invention.
Summary of the invention
The present invention overcomes the deficiencies in the prior art exactly, and a kind of antenatal training belt of brand-new design is provided, to improve security, validity, portability and the ease for use of prenatal culture equipment, the final effect that realizes strengthening prenatal culture; A kind of method that can control volume and audio frequency is provided simultaneously, can effectively helps the user that voice signal is controlled in the rational scope, do not damage the hearing of fetus; The audible segment of this equipment will adopt ELECTROMAGNETIC RADIATION SHIELDING to process, and allow fetus and pregnant woman avoid the injury of electromagnetic radiation.
