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: Embodiments of this application provide a keyboard and an electronic device, implementing press buffering and noise reduction. The keyboard includes a support plate and a plurality of keys located on one side of the support plate. Each key includes a key cap and a lifting/lowering assembly, and the lifting/lowering assembly is located between the support plate and the key cap. The lifting/lowering assembly includes a first support and a second support. The first support and the second support each include a first end and a second end. A first buffer structure is further provided on the inner surface of the key cap. When the key cap is pressed, the second end of the first support is in contact with the first buffer structure, and the second end of the second support is in contact with the first buffer structure.
