The invention discloses a snoring-stopping device. The device comprises five main parts including a sound sensor, an AD conversion module, an MCU control center, a relay isolating switch and a vibrator. The main working process is as follows: the sound sensor collects sound signals of the surrounding environment, and the AD conversion module converts the sound signals into digital quantity for reading of the MCU; the MCU processes the series of read digital signals, the snoring sound recognition algorithm is adopted for distinguishing the snoring sounds, and if the snoring sounds are detected,the vibrator is started through a relay; the vibrator is placed below a pillow, the vibration sense is transmitted to the head of the human body through the pillow, so that the sleeping posture of the human body is changed, and thus the snoring stopping effect is achieved. The snoring-stopping device is concise in structure and low in cost, one-key use is provided, no side effects exist, the pillow using habit does not need to be changed, and certain anti-jamming capacity is provided.
