Self-adaptive noise reduction unit and smart home equipment

The utility model relates to the field of smart home, in particular to a self-adaptive noise reduction unit and smart home equipment, the self-adaptive noise reduction unit is carried in the equipment, and the self-adaptive noise reduction unit comprises a self-adaptive load module and a control module; the self-adaptive load module is connected between a power output end of a power supply module of the equipment and the ground, the self-adaptive load module comprises at least two load groups, the load groups are connected in series or in parallel, each load group is internally provided with a switch piece and a load element, and the control module controls the switch pieces and adjusts the maximum impedance value of the self-adaptive load module, so that the requirement of low power consumption is met, and the service life of the self-adaptive load module is prolonged. A frequency band generating power supply noise is avoided, and vibration of peripheral devices is avoided, so that the noise is reduced and e
