A doorbell system includes a power supply circuit, a smart module, a chime, a chime switch and a control module. The smart module provides a smart function. The chime switch is electrically connected between the control module, the smart module, and the power supply circuit. When the chime switch is turned on, the current flows through the chime under control of the control module. When the chime switch is turned off, the current cannot flow through the chime under control of the control module; consequently, the buzzing sound cannot be generated.
