[0036] Working principle: When in use, the battery provides raw electrical energy, and the step-down voltage regulator circuit converts the unstable voltage of the battery into the stable voltage required by the system, providing a clean and stable power supply to the vibration components, control panel 2 and two small horns 3, ensuring that they work properly;
[0037] During operation, the user operates the device via buttons on the control panel 2.

The main control chip U1 reads and recognizes the signals, parses the user commands from the control panel 2, decodes the digital audio signals, and sends the digital audio signals to the speaker driver chip U3. Chip U3 receives the digital audio signals and control commands from the main control chip U1, decodes and amplifies the weak digital signals into high-power analog signals sufficient to drive the speaker 3. The amplified audio signals are then output through a filter network composed of inductors L1, L2, L3, L4, and capacitors C5, C9, C12, and C15, ultimately driving the speaker 3 to emit sound waves.
[0038] The main control chip U1 outputs a control signal to the vibrator drive circuit chip U4 through pin 13. When the control signal is high, chip U4 starts. The input terminal of chip U4 receives the DAC audio signal from the main control chip U1. The voltage amplitude of this signal determines the vibration intensity. Chip U4 amplifies the input audio signal and directly drives the vibrator SPKL1 to work. The stronger the audio signal, the stronger the vibration, and the weaker the audio signal, the weaker the vibration, thereby achieving the effect of the vibration rhythm and intensity changing with the sound wave.
[0039] The sound waves emitted by the small speaker 3 and the mechanical vibration generated by the vibrator, which changes synchronously with the intensity of the sound waves, act on the user simultaneously. Through the dual stimulation of hearing and touch, the sound wave massage effect is achieved, thereby achieving relaxation and massage, and significantly improving the comfort of the pillow body 1.
