Sound-proof device and electronic equipment

Abstract

The invention discloses a sound-proof device and electronic equipment, and belongs to an electronic field. The sound-proof device is arranged outside the equipment. The equipment is provided with an air inlet and an air outlet. The sound-proof device comprises a shell, pipelines and active noise reduction components. The shell is arranged outside the equipment. The shell is provided with an inlet and an outlet. The inlet is connected with the outlet through the pipeline, and the air inlet is connected with the air outlet through the pipeline. The active noise reduction components are arranged in the pipelines. The electronic equipment comprises a sound-proof device and equipment. The sound-proof device is arranged outside the equipment. According to the embodiment, the sound-proof device is directly arranged outside the equipment through the shell, the medium-high frequency noise of the equipment is directly prevented from external radiation, so that the medium-high frequency noise out of the equipment is attenuated. The equipment is subjected to ventilation and heat dissipation through the pipelines, the low-frequency noise is processed through the active noise reduction components disposed in the pipelines, so that the noise full band out of the equipment is reduced. The noise reduction effect is good, and the equipment is no need of transformation again, so that the original reasonable structure is free of destroy, therefore, the practicability is stronger.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a sound insulation device and electronic equipment. Background technique [0002] Fans are usually installed inside the communication equipment for heat dissipation. When the fan is running, it will generate noise and affect the surrounding environment. In particular, the noise level of many communication equipment exceeds the standards or regulations, which seriously affects the physical and mental health of nearby workers or residents. [0003] At present, for the noise reduction of equipment and chassis with high noise, it is generally to install a sound insulation device on the finished chassis. This sound insulation device is generally a pipe with sound-absorbing material inside. When installing the pipe, it is necessary to The finished product of the chassis that has been processed is subjected to secondary transformation, such as processing a hole on the chassis for the passage ...
