Communication equipment with good denoising effect

Abstract

The invention relates to the technical field of communication facilities and discloses communication equipment with good denoising effect. The communication equipment comprises a shell, wherein a buffering band is fixedly mounted on the inner top wall of the shell; and an elastic band is fixedly connected with the bottom of the shell. According to the communication equipment with the good denoising effect, an antenna is fixedly mounted on the top of a switchboard and receiving efficiency of a signal is effectively improved. The antenna can be manually extended and retracted. When the antenna is idle, the antenna can be retracted to the shortest state, so the antenna is effectively prevented from being bumped. Receiving devices and an output device are fixedly mounted in the shell and the shell is worn on a head, so sound propagation between ears and the outside world is isolated to a certain degree, influence of external noises is greatly reduced, and instruction transmission or receiving efficiency is improved. Sound insulation sponge is set in the gap between receiving devices and receiving slots, so influence of the external noises on communication is further weakened.

Description

technical field [0001] The invention relates to the technical field of communication facilities, in particular to a communication device with good noise reduction effect. Background technique [0002] Communication equipment is abbreviated as ICD in English. Wired communication equipment mainly solves serial communication in industrial field, professional bus type communication, industrial Ethernet communication and conversion equipment between various communication protocols. Wireless communication equipment is mainly wireless AP, wireless bridge. , wireless network card, wireless arrester, antenna and other equipment, wireless communication uses radio waves instead of cables to achieve communication between devices, this communication method has the advantages of fast and simple installation and maintenance, not affected by the on-site terrain environment, and low cost Rich products can meet the different needs of users in terms of communication distance and communication ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a communication device with a good noise reduction effect, which has the advantages of noise reduction, etc., and solves the problem that the existing communication device is often affected by the external environment when in use, such as the surrounding environment is noisy , The sound of the wind is too loud, etc., so that the communication equipment will be noisy when sending and receiving signals, which will affect the use of the entire communication equipment, especially in outdoor construction sites. Leaders such as various foremen need to use communication facilities to direct workers to roughly Construction, various noises on the construction site seriously affect the quality of communication, so that the instruction is not conveyed smoothly, which delays the construction period
