An air compressor includes an audible alarm device (6) mounted to an outlet of a storage container (5) thereof to produce a high-frequency sound for alerting users when compressed air produced in a cylinder (3) thereof exceeds a predetermined value, wherein the sliding cap (66) of the audible alarm device (6) can be driven by the compressed air to perform a quick, slight back-and-forth movement of high frequency, so that the sliding cap (66) can be partially moved out of the opening (12) of an external enclosure (1) and thus exposed to the outside. Through the audible alarm device (6), users can be alerted effectively to overpressure conditions of the air compressor. |
