Description

The electronic timing hypnotic device of time spent base circuit production

Technical field

The invention belongs to electronic technology field, relate to a kind of electronic timing, hypnotic device of time spent base circuit production.

Background technology

Everybody had such cognition in the daily life: when taking train, the rhythmical sound of wheel helps to urge the people sleepy on the contrary; In rainy night, the sound that drips of the patter of rain that rustles or eaves also makes the people sleep especially fragrant and sweetly ...All these is because rhythmical, the appropriate sound can be stabilized people's emotion, makes the people neural calm, can impel brain to be in relaxed state, thereby produce dim sleepiness.

Electronic hypnotic device of the present invention is according to this reason design, making; Electronic hypnotic device is in the time of setting; Utilize electronic installation to send rhythmical simulation rainwater again and again and drop in " ticktack, the ticktack " sound on the step; The insomniac intently listens this sound that drips, and the sound number that perhaps and then drips then can be easy to make the people sleeping.Part gerontal patient and pain disease patient sleep be difficulty comparatively, sleeps for a long time and can not fall asleep, and be the most painful.If often oral stable type of hypnotic drug then is prone to form the dependency to medicine.Facts have proved: this raindrop sound electronic hypnotic device is used for the crowd of this type of patient and partial sleep difficulty, all obtains hypnotic effect preferably.

Test, compare and analyze through kinds of schemes, the present invention only uses a small amount of common components and parts to realize intended purposes.Below specify the electronic timing of this time spent base circuit production, the relevant technologies that hypnotic device is made in detail.

Summary of the invention

Goal of the invention and beneficial effect: rhythmical appropriate sound can be stabilized people's emotion, makes the people neural calm, and brain is in relaxed state, thereby produces dim sleepiness.Electronic hypnotic device of the present invention is made according to this reason; Utilize electronic installation in the time of setting; Send rhythmical simulation rainwater again and again and drop in " ticktack, the ticktack " sound on the step; The insomniac intently listens this sound that drips, and perhaps follows this sound number that drips, and then is easy to make the insomniac sleeping.

Technical characterictic: electronic timing, the hypnotic device of time spent base circuit production; Form by dc source, mono-stable timing circuit, stable multi-oscillation circuit and speaker; It is characterized in that: all use time base circuit NE555 in mono-stable timing circuit and the stable multi-oscillation circuit, in mono-stable timing circuit, also comprise regularly starting key switch (AN).
