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: A finish coat composition, including: 30˜60 parts by mass of film-forming resin, where the film-forming resin includes one or more of acrylic resins and polyurethane acrylate resins; 5˜20 parts by mass of acrylate monomer; 1˜10 parts by mass of photoinitiator; 0.5˜10 parts by mass of leveling agent; 0˜20 parts by mass of matting powder; and 20˜50 parts by mass of solvent. This application further provides a composite material, a middle frame of an electronic device. The finish coat composition according to this application can be crosslinked and cured under an action of ultraviolet light to form a finish coat having good reliability and bonding performance, which is used as a finish coat layer of the middle frame of an electronic device and the battery cover of an electronic device, and has good bonding performance with glue, thereby preventing a screen of the electronic device from falling off.

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.
