Technical Field

The present disclosure relates to the field of communications devices, and in particular, to a communications device.

Background

The main noise source of the communication equipment is a fan, and the main component of the noise is aerodynamic noise, which in turn contains broadband noise and discrete noise (blade/motor frequency doubling noise). At present, the most commonly used sound-absorbing material in the communication industry is sound-absorbing cotton, but because the design space provided by communication equipment is limited, the thickness of the sound-absorbing cotton which can be adopted is generally below 50mm, as shown in fig. 1, the dark black curve in fig. 1 is the noise spectrum when the sound-absorbing cotton is not adopted, and the light black curve is the noise spectrum when the sound-absorbing cotton is adopted, it can be seen that the sound-absorbing cotton is only effective for sound absorption of medium-high frequency and wide frequency above 2000Hz, but cannot effectively absorb noise below 2000 Hz. However, in general, in the communication device, the generated blade/motor frequency doubling noise is mainly noise below 2000Hz, so that the overall noise reduction effect of the sound-absorbing cotton in the communication device is very limited, and the noise reduction requirement of the communication device cannot be met. In addition, because the sound-absorbing cotton is a resistive sound-absorbing material, the wind resistance of the system can be improved when the sound-absorbing cotton is applied to air-cooled communication equipment, and the heat dissipation of the system is influenced.

Disclosure of Invention

The embodiment of the present disclosure provides a communication device, which mainly solves the technical problem that: at present, noise is eliminated by a mode of arranging sound absorption cotton in communication equipment, the whole noise reduction effect is very limited, the noise elimination requirement of the communication equipment cannot be met, and meanwhile, the wind resistance of a system can be improved to influence the heat dissipation of the system.

To solve the above technical problem, an embodiment of the present disclosure provides a communication device, including:

an apparatus body and a gas flow passage within the apparatus body; at least one sound absorption unit is arranged on the inner side wall of the gas flow channel and/or the flow channel opening of the gas flow channel, and a channel for gas to flow out is reserved on the gas flow channel by the sound absorption unit;

the sound absorption unit includes: a frame body which is enclosed to form at least one opening and an elastic film; the elastic film is in a tensioned state and is arranged in the at least one opening; when the noise frequency in the gas channel is consistent with the working frequency of the sound absorption unit, the vibration of the elastic membrane enables the fluid in the gas channel not to vibrate any more, so that the noise of the frequency is eliminated.

An embodiment of the present disclosure further provides a communication device, including:

an apparatus body and a gas flow passage within the apparatus body; the gas flow channel is a hollow tubular flow channel formed by enclosing four or more sound absorption units;

the sound absorption unit includes: a frame body which is enclosed to form at least one opening and an elastic film; the elastic film is in a tensioned state and is arranged in the at least one opening; when the noise frequency in the gas channel is consistent with the working frequency of the sound absorption unit, the vibration of the elastic membrane enables the fluid in the gas channel not to vibrate any more, so that the noise of the frequency is eliminated.
