A respirator structure is provided, which includes a gas supply device. The gas supply device includes a supply device main body, an absorbing vibration module and a gas generating module. The supply device main body is a hollow structure and has an accommodating space and two via holes. The absorbing vibration module is on the accommodating space and has a substrate layer, a flow channel layer, a bearing layer, and a gas generating module. A flow channel layer has a passage and a passage opening. A bearing layer has a bearing part and a bearing opening. The gas generating module has an air inlet and an air outlet. Air flows to the passage through the via holes, the accommodating space and the passage opening, and the gas generating module inhales the air by the air inlet to produce and discharge the air flow outside the supply device main body.
