Signal shielding sound insulation box

Abstract

The invention relates to a signal shielding and sound insulation box which is mainly composed of a sound insulation sealing cover, a sound insulation outer liner, a sound insulation inner liner and a shielding core liner. The sound insulation sealing cover covers the sound insulation outer liner and the sound insulation inner liner. The sound insulation outer liner is of a double-layer structure composed of an inner plate and an outer plate, and both the inner plate and the outer plate are metal plates. The sound insulation inner liner is accommodated in the sound insulation outer liner. The sound insulation inner liner is composed of a double-layer metal plate. The shielding core liner is of a tray-shaped or box-shaped structure, and is accommodated in the sound insulation inner liner. The outer wall of the shielding core liner is internally pasted with a sealing strip. The side walls of the shielding core liner are inserted downward into electromagnetic sealing reeds, and the two layers of electromagnetic sealing reeds are fixed to the bottom surface of the metal shielding core liner. A rubber vibration isolation block is arranged in at least one of the three positions: between the sound insulation outer liner and the sound insulation inner liner, between the sound insulation inner liner and the shielding core liner, and at the bottom of the sound insulation outer liner. The signal shielding and sound insulation box has high sound insulation performance. Wiretapping and recording can be effectively avoided by putting a mobile phone or other mobile electronic equipment in the sound box so as to ensure the confidentiality of special occasions.

Description

technical field [0001] The invention belongs to sound insulation equipment, in particular to equipment used for sound insulation treatment of mobile phones or other mobile electronic equipment. Background technique [0002] With the continuous development of the economy and society, and the continuous improvement of the level of science and technology, various means of stealing secrets emerge in an endless stream, and some important decisions and information are stolen by unscrupulous elements, causing heavy losses to enterprises and groups. The security of corporate secrets is facing unprecedented threats, and the struggle between stealing and anti-theft has become more acute. [0003] As a common communication tool for people, mobile phones are inseparable in any place, but on some important occasions or confidential meetings, conversations or decision-making information will be eavesdropped through mobile phone recordings (including automatic shutdown devices and remote s...

Problems solved by technology

However, the structure of the mobile phone storage cabinet can still receive mobile phone signals, so it cannot achieve complete sound insulation, and there is still a risk of eavesdropping and recording
