Sleep-aiding pillow with surround sound field and regulation and control method thereof

Abstract

The invention discloses a regulation and control method of a sleep-aiding pillow with a surround sound field. Loudspeakers are arranged at the four corners of the pillow body, pressure power generation components and a pressure sensing array are arranged in the middle of the pillow body, the pressure sensing array comprises multiple rows of pressure sensing sets arranged in parallel, and one pressure power generation components are arranged between every two adjacent rows of pressure sensing sets. The method comprises the following steps: extracting different characteristic values according toa pressure sensing matrix, including left-right and up-down pressure difference coefficients; extracting different characteristic values according to the pressure sensing matrix; and adjusting and controlling the volume of each loudspeaker according to the characteristic values generated by the pressure sensing matrix. The surrounding sound field of the head of a sleeper can be studied, judged and regulated in real time according to the judgment of the position of the pillow where the head is located when the sleeper sleeps, the effect that sound moves along with the sleeper is achieved, thephenomenon that sound fields of different poses are uneven can be effectively avoided, and therefore the sleep assisting effect of the pillow is improved.

Description

technical field [0001] The invention belongs to a control method of an electronic pillow, in particular to a control method of a sleep aid pillow with a surround sound field. Background technique [0002] Sleep is a very important content in human life, and the improvement of sleep quality is conducive to the health of human body and mind. Pillow is an important sleep aid tool. In addition to changing the filling material inside the pillow, there are currently many smart pillows with sleep detection and music playback. For example, the Chinese invention patent application of CN108056765A discloses a device that can automatically monitor the human body. Smart pillows and cushions in a healthy state, CN 110975107A a music sleep aid pillow and music sleep aid method, CN109924948A a smart pillow control method and system, most of the existing products involve sensing, communication and judgment, and realize the mobile terminal Software control operations, such as voice control ...

AI Technical Summary

Problems solved by technology

[0003]However, there are still some shortcomings in these products and patents. The speakers are arranged with 2 or 3 speakers on the left and right of the center, and only form a fixed center of stereo two-channel The sound field will be destroyed once the human head deviates from the sound field on the pillow position; at the same time, the existing pillow cannot describe the position of the head posture change when the human body sleeps, and thus cannot automatically set the surround sound field in real time; the existing smart pillow They are all based on external links and control, and do not make full use of the head activity energy in the light sleep state of the human body, and do not fully collect and store this part of the energy signal; at the same time, although existing products and patents have some control methods, most of them are Some do not disclose perceptual control calculation methods with targeted sensor layout and characteristic quantities
