Embodiment Construction
[0057] The present invention will be described in detail below with reference to specific embodiments.
[0058] The invention relates to a sleep state feedback sound sleep control system in a closed-loop path, which includes a sensor, a controller and an actuator.
[0059] The sensor is a brain wave detection device, which collects EEG signals of human sleep in real time and sends them to the controller.
[0060]The controller is a computer, which recognizes the sleep period of the human body according to the EEG signal, generates a sound model similar to the sleep spectrum of the next stage, and sends it to the actuator.
[0061] The actuator is a hypnotic sound player, which plays sleep-aiding sounds. The actuator uses DSP as the core, and drives the EDIFIER R12U multimedia active speaker to emit sleep-aiding sounds through a power amplifier circuit.
[0062] The controller judges the sleep state of the human body by identifying the EEG signal, and provides the actuator wit...
