Abstract: A notebook computer includes a control chip, a speaker, and the fan. The control chip and the fan are disposed inside a chassis of the notebook computer. The method includes: controlling, by the control chip, the speaker to send a first sound signal, where the first sound signal and a first noise signal that is generated by running of the fan have opposite phases and a same frequency. The first sound signal is used to cancel the first noise signal.

Abstract: Embodiments of this application provide a fan apparatus and an electronic device. The fan apparatus includes a first housing, a second housing, a fan blade unit, and a fence member located in the first housing. The fan blade unit is rotatably disposed in an accommodating cavity in the first housing. The fence member is located on a circumferential outer side of the fan blade unit. The second housing is covered on the first housing and the fence member, and encloses at least one resonant cavity together with the first housing and the fence member. The resonant cavity communicates with the accommodating cavity through a muffling hole on a cavity wall. Air in the resonant cavity resonates under excitation by an airflow of the fan blade unit. The fan apparatus of this application helps alleviate a noise problem caused by a fan with a high rotational speed, without affecting a heat dissipation effect of an existing electronic device.

Abstract: This application provides a fan and an electronic device. The fan includes a body, and an air duct, an air outlet and a flow guiding inlet are formed in the body; the air duct includes an air inlet area and an air outlet area, and a flow guiding member is disposed in the air outlet area; the flow guiding member and the body form a first channel, a second channel, and a third channel. After a main airflow in the air inlet area enters the first channel and the third channel, a negative pressure area is formed at the flow guiding outlet, a differential pressure exists between air pressures in the negative pressure area and the second channel, and the differential pressure enables air to enter the flow guiding cavity from the flow guiding inlet to form an induced airflow, thereby increasing an air output.
