Abstract

The utility model relates to an electronic device which is composed of a circuit and a shell. The positive and the negative power ends of a speech circuit (1) are connected with a direct current power supply (4) and a switch (5) in series, and the output end of the speech circuit (1) is connected with a transistor (2) and a loudspeaker (3) in series, and the emitter of the transistor (2) is connected with the negative pole of the loudspeaker (3). The device sends out a heart jumping sound with a standard frequency of 72 times per minute during the process of work. The device can reduce the frequency and the time of cry of infants, and meanwhile, the increasing rate of the body weight of infants who using the device is higher than the increasing rate of the body weight of common infants.

Description

Cry-stopping health device for infants

This utility model relates to a kind of help baby to be stopped to cry, and can improve the electronic device of infant weight rate of increase.

Baby crying is each family's pain in the neck feelings, directly influences household's work and rest.Also reflected simultaneously and baby's feared state of mind to external world, will influence baby's physical and mental health as not eliminating baby's this psychology.Still there is not at present a kind of device that helps the baby only to cry that is specifically designed to.

The purpose of this utility model provides the device that a kind of baby of help only cries.Simultaneously, can increase infant weight effectively.

The new purpose of this practicality is achieved in that with a sound circuit and dc source, speaker, audion, switch and constitutes the loop.After closing a switch, sound circuit sends the audio-frequency electric signal, emits the heartbeat simulated sound by audion, speaker, and the standard frequency of this sound is per minute 72 times, is the average palmic rate value of adult (mother).After the baby hears mother's heart beating simulation sound, since very sensitive to mother's heartbeat, the feared state of mind to external world eliminated, stop to cry, promote baby's physical and mental health.

This utility model is simple in structure, volume is little, cost is low, and practicability and effectiveness helps the baby only to cry, and eliminates family's worry.The contrast experiment: the baby of numbers such as two groups, having listened one group of number of times time ratio of crying of the health care device sound of only crying to reduce half for common group.Simultaneously, the baby is easily sleeping, and the weight increase rate is higher than common baby.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Accompanying drawing be according to the utility model proposes the baby only cry the health care device circuit diagram.Describe the detail of device in detail below in conjunction with this figure.

This device comprises: a sound circuit (1) can be selected integrated circuits such as XD, MOS for use; An audion (2) can select 9014 for use, 3DG6,3DG12 etc.; A speaker (3) can be selected YX or QMB minisize dc sounder (not carrying source of sound) etc. for use; The whole electronic component of two joint (4) switches of No.5 cell (5) is installed in the shell of cigarette case size.This shell also can be designed to the toy image according to baby's characteristics.

Claims (1)

1. A kind of baby health care device of only crying, it is made up of cabinet and the circuit of putting into it, its feature is: the sound circuit (1) of recording the heart acoustical signal, its positive-negative power end in and the series connection of DC current (4) and switch (5), its outfan and audion (2), speaker (3) series connection (audion (2) emitter stage connects the speaker negative terminal).
