Description

A kind of multifunctional electronic Antenatal training instrument

Technical field

The utility model relates to a kind of multifunctional electronic Antenatal training instrument, belongs to prenatal culture equipment technical field.

Background technology

Prenatal culture refers to promote on fetus physiology and psychological healthy development growth, and then promote the maturation of its cerebral function, somatic movement function, sensor capability and nervous system function, guarantee that pregnant woman successfully can tide over the hygienic measures of each side such as spirit, diet, environment, work and rest that the pregnancy period takes simultaneously; The instrument that can realize the object of prenatal culture is Antenatal training instrument; Antenatal training instrument is not simple music player, or sound equipment etc., but a kind of instrument that can promote fetal intelligence, pass through Antenatal training instrument, effectively various signal can be communicated to fetus, by the science " stimulation " to fetus, promote the growth of fetal central nervous system, or cultivate personality and the hobby of fetus; By Antenatal training instrument, can make fetus in the belly of mother, obtain the edifying of music, baby's health can be made clever; Existing Antenatal training instrument function ratio is more single, does not generally have the monitoring of fetus fetal heart sound, and to its recording and the function stablizing Mood of Pregnancy.Chinese patent (application number: 200420000091.0) disclose a kind of Antenatal training instrument, comprise fuselage body and an audio input-output device, wherein fuselage body is provided with the interface that at least two audio input-output device connect, be connected with microphone and/or earphone and/or transaudient loudspeaker respectively, described Antenatal training instrument also comprises an electronic reading device, electronic reading device is placed in fuselage body, fuselage body separately comprises a LCD flat panel display and controls button, and the output terminal of electronic reading part is shown on LCD flat panel display by the control button of fuselage body; Owing to having settled an electronic reading device in Antenatal training instrument, such pregnant woman or father and mother not only can go study from the angle of the sense of hearing or carry out early education to foetus, and electronic reading device can be utilized to learn and grasp a large amount of pregnant the early, middle, late stage even raising of cradle, education material by vision; Technique scheme can not reduce the intense strain of pregnant woman well, is unfavorable for the growth of baby.

Summary of the invention

(1) technical matters that will solve

For solving the problem, the utility model proposes a kind of multifunctional electronic Antenatal training instrument; Pregnant woman can be realized and fetus is talked with, stablize Mood of Pregnancy, also can monitor fetus fetal heart sound simultaneously.

(2) technical scheme

Multifunctional electronic Antenatal training instrument of the present utility model, comprises housing, and arranges the prenatal culture circuit of case inside; Described prenatal culture circuit comprises controller, and the audio record circuit be electrically connected with controller I/O mouth; And the modulate circuit to be electrically connected with audio record circuit; And the single-pole double-throw switch (SPDT) to be electrically connected with modulate circuit; And in single-pole double-throw switch (SPDT) the Doppler's oscillator be electrically connected and mouth of recording; And the EEPROM to be electrically connected by iic bus with controller; And to the 5V power supply that controller is powered.

Further, described EEPROM is directly assembled by eeprom chip and peripheral circuit thereof.

Further, the output circuit that described audio record circuit connects an EMC input circuit and a power amplifier by ISD4004 chip speech input interface and voice output interface is formed.

Further, described recording mouth and single-pole double-throw switch (SPDT) are installed on surface of shell.

As preferably embodiment, described Doppler's oscillator is directly made up of the external member after assembling.

Further, described closure periphery is provided with loose collar.

(3) beneficial effect

Compared with prior art, multifunctional electronic Antenatal training instrument of the present utility model, function ratio is more complete, can realize prestoring and playing of fetus fetal heart sound, can play music and realize mother and sons' dialogue; Its overall integrated circuit that adopts is as building core, and good stability, can cultivate foetus and stable pregnant woman's intense strain well.

Accompanying drawing explanation

Fig. 1 is prenatal culture schematic block circuit diagram of the present utility model;

Fig. 2 is audio record circuit principle schematic of the present utility model.

Because EEPROM directly adopts chip to build circuit, and its peripheral circuit comparative maturity in the prior art, do not repeat them here;

Because modulate circuit can form filtering circuit by electric capacity, or all can realize the adjustment to circuit by amplifier formation comparer; It belongs to prior art, does not repeat them here;

The utility model integrated circuit forms a system by above-mentioned module and audio record circuit, specific as follows:

Embodiment 1:

Multifunctional electronic Antenatal training instrument as shown in Figure 1, comprises housing, and arranges the prenatal culture circuit of case inside; Described prenatal culture circuit comprises controller, and the audio record circuit be electrically connected with controller I/O mouth; And the modulate circuit to be electrically connected with audio record circuit; And the single-pole double-throw switch (SPDT) to be electrically connected with modulate circuit; And in single-pole double-throw switch (SPDT) the Doppler's oscillator be electrically connected and mouth of recording; And the EEPROM to be electrically connected by iic bus with controller; And to the 5V power supply that controller is powered; Described EEPROM is directly assembled by eeprom chip and peripheral circuit thereof.

As shown in Figure 2, the output circuit that described audio record circuit meets an an EMC input circuit D1 and power amplifier D2 by ISD4004 chip U1 speech input interface and voice output interface is formed.

By switch being beaten to Doppler's oscillator place, fetus fetal heart sound can be realized to be received by Doppler's oscillator through maternal abdominal, delivering to audio record circuit through modulate circuit and carrying out recording and playing, allowing pregnant woman understand fetal state, help it to loosen mood.
