RU220544U1 - Acoustic mobile mini-cabinet - Google Patents

Abstract

The utility model relates to the construction industry, namely prefabricated mobile multi-purpose structures designed to protect primarily speech confidential information from leakage through technical channels, and can be used in enterprises, studio apartments, shopping centers, exhibition events, and Open-style offices Space to ensure confidentiality and comfort of negotiations or telephone conversations.

The objective of the claimed utility model is to protect speech information from leakage through acoustic and vibration channels outside the mini-office.

The problem is solved by the fact that the acoustic mobile mini-cabinet contains a sound-absorbing body made in the form of a vertically oriented parallelepiped, one of the sides of which is equipped with a glazed translucent door, while the mini-cabinet is equipped with a power supply system, ventilation, electrical network, as well as furniture, additionally contains a speech information protection module that synthesizes white and speech-like noise, as well as acoustic and vibration emitters installed on the body and door.

As a result of assessing the effectiveness and sufficiency of measures to protect against information leakage through acoustic and vibroacoustic channels through instrumental monitoring, it was established that the effectiveness of protection of an acoustic mobile mini-office complies with the requirements of regulatory legal acts for the protection of objects from information leakage through acoustic and vibroacoustic channels, verbal intelligibility is not exceeds 0.19. Thus, this mini-office can be used in government or commercial institutions to organize a temporary workplace that ensures the protection of confidential speech information.

Description

The utility model relates to the construction industry, namely prefabricated mobile multi-purpose structures designed to protect primarily speech confidential information from leakage through technical channels, and can be used in enterprises, studio apartments, shopping centers, exhibition events, and Open-style offices Space to ensure confidentiality and comfort of negotiations or telephone conversations.

There is a known design of a room with a sound-absorbing fence containing smooth and perforated walls, between which there is sound-absorbing material. Sound waves pass through the perforated wall, fall on a layer of soft sound-absorbing material, losing their energy, which provides protection against the penetration of sound waves [Sound-absorbing acoustic fencing of an industrial premises: Pat. 2348750 RU, MPK (2006) E01B 19/00, F01N 1/04 / Kochetov O.S. [and etc.]; applicant Kochetov O.S., Golubeva M.V., RU; application 06/08/2007; publ. 03/10/2009]. However, the structural design of such a room is of a specific nature and is advisable mainly for rooms with a corresponding level of noise.

A mobile modular structure is also known, containing a floor, walls and a ceiling, the walls being made of double fiberglass panels interconnected with polyurethane foam, where the latter, in turn, are made on the basis of a matrix by applying composite materials to the matrix. The structural elements of such a structure are connected to each other with hardware, and the joints are treated with silicone sealants [Mobile modular structure: Pat. 85464 UA, IPC (2006) E04N 1/12 / Yeshil Mustafa; Petitioner Yeshil Mustafa, TR; application 04/10/2013; publ. November 25, 2013]. The positive properties inherent in such a structure are the ease of its assembly, but the disadvantage is that they do not provide a sufficient level of sound insulation, and the dismantling process is labor-intensive.

The closest analogue in technical essence to the claimed acoustic mobile mini-cabinet is a multi-purpose mobile cabin, made in the form of a vertically oriented parallelepiped and containing a frame connected to the base, to which vertical panels and at least one horizontal panel are attached, as well as a door, and on the panel a sound-absorbing coating is applied, and the base, frame and doors are fastened together with detachable connections, the cabin is equipped with engineering equipment, including ventilation and power supply systems, and a power supply source. In addition to the above, the cabin is equipped with furniture [Multi-purpose mobile cabin: Pat. 137355 UA, MPK (2006) E04N 1/12 / Bukovsky K.B.; applicant Bukovsky K.B., UA; application 06/24/2019; publ. 10.10.2019].

A significant disadvantage of the known cabin is the lack of means of actively protecting speech information from leakage through acoustic and vibration channels outside the cabin.

The objective of the claimed utility model is to protect speech information from leakage through acoustic and vibration channels outside the mini-office.

The problem is solved by the fact that the acoustic mobile mini-cabinet contains a sound-absorbing body made in the form of a vertically oriented parallelepiped, one of the sides of which is equipped with a glazed translucent door, while the mini-cabinet is equipped with a power supply system, ventilation, electrical network, as well as furniture, additionally contains a speech information protection module that synthesizes white and speech-like noise, as well as acoustic and vibration emitters installed on the body and door.

The utility model is illustrated by the following drawing.

In fig. Figure 1 shows a general view of the acoustic mobile mini-cabinet.

In accordance with Fig. 1 acoustic mobile mini-cabinet contains a sound-absorbing housing 1, equipped with a power supply system, ventilation, electrical network, as well as furniture, a glazed translucent door 2, a speech information protection module 3, acoustic emitters 4 and vibration emitters 5 installed on the housing 1 and door 2 .

The claimed mini-office works as follows. At the moment the conversation starts inside the mini-office, the speech information protection module 3 starts the synthesis of speech-like and white noise, which is reproduced by means of acoustic emitters 4 installed at the input and output of the supply and exhaust ventilation system of the building 1, and vibration emitters 5 installed on the housing 1 and glazed translucent door 2.

As a result of assessing the effectiveness and sufficiency of measures to protect against information leakage through acoustic and vibroacoustic channels through instrumental monitoring, it was established that the effectiveness of protection of an acoustic mobile mini-office complies with the requirements of regulatory legal acts for the protection of objects from information leakage through acoustic and vibroacoustic channels, verbal intelligibility is not exceeds 0.19. Thus, this mini-office can be used in government or commercial institutions to organize a temporary workplace that ensures the protection of confidential speech information.
