Nature-sound-imitated sleep instrument

Abstract

The invention discloses a nature-sound-imitated sleep instrument, which comprises a control unit, a display screen, an operation key, a flash memory, a second processing module, an audio amplificationmodule and a power supply module, wherein the control unit is provided with an MCU, a digital audio processor and a first processing module used for audio coding and digital-to-analogue conversion, wherein the digital audio processor and the first processing module are connected to the MCU, and the digital audio processor is connected to the first processing module; the display screen is connected to the control unit; the operation key, the control unit is connected to the control unit; the flash memory is used for storing the natural music for sleep aiding and is connected to the control unit; the second processing module is used for audio band-pass filtering, sound effect processing and electronic volume control and is connected to the control unit; the audio amplification module is connected to the second processing module and a horn respectively; and the power supply module is used for supplying power to the sleep instrument. According to the nature-sound-imitated sleep instrument, the nature sound is restored through a multimedia application technology, so that people can fall asleep in the nature atmosphere at any time and any place, and thus the hypnosis effect is achieved,and meanwhile, the direct damage to a human body caused by electromagnetic waves generated by the conventional sleep instrument is also avoided.

Description

Technical field [0001] The invention relates to a sleep instrument, in particular to a natural sound sleep instrument. Background technique [0002] The existing electronic sleep devices promote human sleep in the same way as the following three. The first is to use a sleep instrument to emit low-frequency electromagnetic waves, which can stimulate the human brain and gradually reduce the excitement of the brain, so that people can fall asleep quickly; the second way to promote human sleep is the traditional biofeedback method , It uses a sleep instrument to send stimulation signals to the brain, so that the brain can make adjustments according to the different signals. The signal is getting lower and lower, and the excitement of the brain gradually decreases, and finally achieves the effect of promoting people's sleep; the third type It is a way of digital frequency synthesis of bionic radio waves. This sleep instrument can emit bionic radio waves to make the brain appear regul...
