Some products can be listened to the breathing condition of sleep in-process at present on the market, but need bind to dress on user's health, influence user's sleep comfort level, and user experience is not good. Still other products use displacement sensors to continuously detect the displacement change caused by respiratory activity, and then analyze the respiratory frequency and respiratory effort according to the displacement change information. However, the displacement sensor is used for respiratory detection, so that respiratory sound in the respiratory process cannot be collected, and the respiratory sound cannot be analyzed in detail. When a user has respiratory abnormalities such as cough, snoring, wheezing, dry rale and the like in the sleeping process, the respiratory abnormalities are probably not evaluated by detecting the respiration through the displacement sensor. For example, when a user coughs or performs a turning-over action, the displacement sensor can detect large displacement changes, and the coughs or the turning-over action is difficult to distinguish by the displacement changes alone; snoring, wheezing, rale, etc. are more difficult to detect from displacement changes.
