Embodiment Construction

[0020] The present invention is described in further detail below in conjunction with accompanying drawing:

[0021] Such as figure 1 As shown, firstly, random white noise is generated by MCU, and pink noise data is generated through a 63-order all-pole filter;

[0022] Store and read data with SD memory module through SPI; send data to audio codec chip through integrated interchipsound (I2S) to generate pink noise audio signal and output it through earphone; realize OLED parameter display through SPI; The parameter adjustment is realized with a digital rotary encoder.

[0023] The invention adopts lithium battery for power supply, and selects the charging chip BL4054 for the lithium battery. Its charging current can reach up to 800mA, and the charging voltage is stable at 4.2V. The lithium battery can be charged directly from the USB port, and it also has an overvoltage protection function.

[0024] The S-808xxC series is a series of high-precision voltage detectors develop...

Abstract

The invention discloses a pink noise generator for brain memory consolidation stimulation equipment. The pink noise generator is composed of a main control module, a power module, a storage module, anaudio module, a display module, a rotary coding switch module and an output module; the power module, the audio module, the display module and the rotary coding switch module are in unilateral connection with the main control module; the storage module is in bidirectional connection with the main control module; and the audio module is in unilateral connection with the output module. The pink noise generator of the invention can generate pink noise that best matches pink noise parameters. The generator has a simple structure, stable performance and powerful functions, and is especially suitable for brain memory consolidation stimulation equipment.

Description

Technical field: [0001] The invention belongs to the technical field of medical devices, in particular to a pink noise generator used for brain memory consolidation stimulation equipment. Background technique: [0002] Pink noise, also known as inverse frequency noise, is defined as a gentle, soothing sound with the same energy in each octave. In essence, pink noise is the background noise we hear in our daily environment , is the most common noise in nature. Its frequency distribution range is very wide, the minimum is close to zero Hz, and the maximum is close to 20,000 Hz. Because its characteristics are close to those of pink light, it is called pink noise. [0003] Based on these characteristics of pink noise, a lot of experimental research has been done and many valuable research results have been obtained. Researchers have found that pink noise can help people fall asleep and improve people's sleep quality. As early as 1982, AndrenL and LindstedtG et al. found in th...
