1. An air conditioner, comprising:
an indoor unit; and
an outdoor unit, including:
a housing;
a compressor disposed in the housing, and the compressor being provided with a pipe;
a first damping member disposed on the pipe; and
a second damping member disposed on the pipe and located at a preset position of the pipe, the preset position being a portion of the pipe on which at least one of vibration or stress is concentrated, the first damping member and the second damping member being configured to change a natural resonant frequency of the pipe to a target frequency, the target frequency being different from an operating frequency of the compressor operating at a high frequency, and the second damping member including:
a housing assembly including a housing body, wherein a closed cavity is provided in the housing body, and a damping material is filled in the cavity; and
a clamping groove disposed on the housing assembly and connected with the pipe, wherein the clamping groove is located on a side of the cavity proximate to the pipe, so that a center of gravity of the second damping member deviates from a center of gravity of a portion of the pipe connected with the clamping groove.
