Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are to be construed broadly, e.g., "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-7, the double-layer isolation ultra-silent office telephone booth provided in this embodiment includes a housing 1 and a soundproof door 2 fixed on the housing 1, where the soundproof door 2 includes a door frame 21 fixed at an opening of the housing 1, a sealed door 22 movably connected to the door frame 21 and located outside the housing 1, and a silent door 23 movably connected to the door frame 21 and located inside the housing 1, and the soundproof door is configured as two soundproof measures, namely a sealed door and a silent door, so that sound transmission can be better blocked.

Further, in the present embodiment, as shown in fig. 1 to 7, the closed door 22 includes a front door 221 movably connected to the door frame 21, a front gasket 222 fixed to one side of the door frame 21, and a rear gasket 223 fitted to the front gasket 222 and fixed to the door frame 21, a gap is left between the conventional door and the conventional door, sound can pass through the gap, if the gap and the hole are formed, the sound insulation amount of the partition wall is greatly reduced, and if the sound insulation amount of the wall body itself reaches 50dB and one ten thousandth of the gap and the hole are formed in the wall, the total sound insulation amount is reduced to 40 dB. In order to prevent the gap between the structure, this embodiment is through the sealing washer that matches the adaptation mutually at sealed door and door frame direct setting, is that there is not the space to exist between door and the casing, and give sound insulation that can be better, and all install magnet board or magnet strip in preceding sealing washer 222 and the back sealing washer 223, can make preceding sealing washer 222 and the inseparable laminating of back sealing washer 223 be in the same place, and the laminating is compacter, and sealing performance is better, blocks the sound propagation.

Further, in the present embodiment, as shown in fig. 1 to 7, the door frame 21 is a metal door frame or a solid wood door frame, the front door 221 is a metal door or a wood door, and the metal material and the wood material have better sound insulation effect than other materials such as plastic and composite board.

Further, in this embodiment, as shown in fig. 1 to 7, the soundproof door 23 is an outer-wrapped soundproof door, the soundproof door 23 includes a solid wood board 231, an artificial leather layer 232 wrapped around the solid wood board 231, and a rock wool layer 233 between the artificial leather layer 232 and the solid wood board 231, the leather, the artificial leather, and the like have air-tight, strong tension and soft data, and can transmit sound through a resonance frequency of the sound, the rock wool is a porous sound-absorbing material, and has a sound absorption principle that there are many tiny gaps in the material, so that there is a certain ventilation property, when the sound wave is incident to the inside, the vibration of the air in the small hole or the gap is caused, the air in the center of the small hole can freely respond to the compression particles of the sound wave, the vibration speed of the air close to or on the surface of the material is slow, and the kinetic energy of the air is continuously converted into heat energy due to friction and viscous resistance of the air, in addition, heat exchange is continuously generated between the air in the small holes and the hole walls, so that a considerable part of the heat is absorbed by being converted into heat energy, the sound is effectively reduced, and the sound can be isolated to a certain extent due to the absorption of sound energy. Rock wool is wrapped in the artificial leather, so that sound absorption and sound insulation can be better achieved.

Further, in this embodiment, as shown in fig. 1-7, the housing 1 includes two layers of metal plates 11 and a soundproof cotton layer 12 located between the two layers of metal plates 11, various sound sources generate vibration to generate noise, the noise can be propagated through air medium, the metal plates pass through the noise, the soundproof glass attenuates the noise one by one, especially when the noise passes through the soundproof damping glue, the medium frequency noise and the high frequency noise are absorbed, distorted, damped and attenuated by the soundproof damping glue, the medium frequency noise and the high frequency noise can be effectively filtered, and finally the noise entering the room is only about 5%, therefore, soundproof cotton is arranged in the middle of the two layers of metal plates, and the effect of blocking the sound is better.

Further, in this embodiment, as shown in fig. 1 to 7, the inner wall of the housing 1 is sprayed with a sound insulation damping coating layer, in this embodiment, preferably, the sound insulation raw material is a nano multilayer structure material, the sound insulation and noise reduction effect of the coating depends on the loss factor thereof, so as to form a damping constraint structure, when sound impacts the pipeline wall to begin to generate sound and vibration, the sound insulation damping coating of the pipeline wall will form a damping protective layer on the pipeline to increase the pipeline density, and effectively convert the mechanical energy of the sound wave into thermal energy to dissipate, thereby significantly improving the sound insulation effect of the wallboard.

Further, in the present embodiment, as shown in fig. 1-7, the bottom and/or the top of the housing 1 is provided with vent holes, if the phone booth has a small volume, the time for a person to make a phone call in the phone booth is too long, air cannot circulate due to the tightness, and fine and tortuous vent holes may be formed around the housing 1.

In this embodiment, the operation of the dual-layer isolated ultra-silent office kiosk as provided in fig. 1-7 is as follows:

sound passes through the medium and propagates, blocks sound propagation or reduces the sound decibel through possessing the structure that sound was inhaled in giving sound insulation, sets up the door of telephone booth twice, and door and frame airtight processing, and door and frame all adopt metal or wooden simultaneously, adopt double-deck metal sheet to fill soundproof cotton and adopt outer parcel leather of timber and soundproof cotton with interior door (silence door) with the casing, all are the double-deck sound insulation measure of adoption to reach the effect of super-silent.

To sum up, in this embodiment, according to the double-deck ultra-silent office call box of keeping apart of this embodiment, the double-deck ultra-silent office call box of keeping apart that this embodiment provided is through setting up the casing that has double-deck metal sheet, all wraps up synthetic leather and soundproof cotton's silence door around, and set up twice airtight door and soundproof cotton to reach the double-deck purpose of blocking and weakening sound.

The above description is only for the purpose of illustrating the present invention and is not intended to limit the scope of the present invention, and any person skilled in the art can substitute or change the technical solution of the present invention and its conception within the scope of the present invention.
