1. A high flow nasal canula (HFNC) system, comprising: a controller, at least one first sensor, a compensating device, a first housing disposed with the at least one first sensor, and a second housing disposed with the compensating device;
wherein the controller is communicatively connected with the at least one first sensor and the compensating device, respectively;
the at least one first sensor is configured to sense vibration of the first housing to collect first sensing data and send the first sensing data to the controller;
the controller is configured to receive the first sensing data collected by the at least one first sensor, generate a first driving signal according to the first sensing data, and send the first driving signal to the compensating device; and
the compensating device is configured to receive the first driving signal generated by the controller according to the first sensing data, wherein the first driving signal is used to cause vibration of the compensating device according to the first driving signal, and vibration of the second housing caused by the vibration of the first housing is compensated by the vibration of the compensating device.
