Problems solved by technology

[0005] However, the problem is that when the above-mentioned cooling device is in working condition, the airflow generated by the high-speed rotation of the fan forms the main noise source of the cooling device, which causes great disturbance to the user and affects the comfort of use.
[0006] Similarly, other hardware such as hard disks and optical drives can also produce similar noises when they are running, which affects the comfort of using the computer

Abstract

The invention discloses a noise-reducing hardware combination and a computer. The noise-reducing hardware combination comprises hardware and a noise-reducing device; the hardware is internally provided with at least one noise source, and the noise-reducing device is fixedly arranged in a corresponding spacial position at the periphery of the noise source; the noise-reducing device comprises a first surface, at least two through holes and a sealed cavity layer, wherein the first surface is fixedly arranged in the corresponding spacial position at the periphery of the noise source, the through holes are arranged on the first surface, and the sealed cavity layer is arranged in the direction of the first surface, which is far from the noise source; noise waves generated by the noise source ofthe hardware enter the sealed cavity layer through the at least two through holes, and the energy of the noise waves is transformed to heat, thus the noise is reduced. The noise-reducing hardware combination can consume the energy of the noise wave generated by the noise source so as to reduce the noise generated from the running of the hardware. The computer comprises the noise-reducing hardwarecombination, and the system of the computer runs by generating low noise, thus the computer is more comfortable to use.

Description

technical field [0001] The invention relates to the technical field of computer hardware, in particular to a noise-reducing hardware combination and a computer. Background technique [0002] At present, with the rapid development of computer technology, desktop computers and notebook computers have pervaded all areas of people's life and work, bringing great convenience to people. However, computers will also produce certain noises when they are running. The comfort has caused adverse effects. [0003] In fact, the noise when the computer is running mainly comes from hardware such as fans and hard disks. This kind of hardware generates noise due to mechanical movement when the computer is running. Air volume for heat dissipation will inevitably lead to a further increase in system noise. [0004] For example, figure 1 It is a cooling device for a notebook computer in the prior art, and the cooling device includes: a metal plate 1, a heat pipe 2, a heat sink group 3 and a ...
