Safe and noiseproof telephone booth metal shell and manufacturing method thereof

Abstract

The invention belongs to the technical field of telephone booth metal shells, and particularly relates to a safe and noiseproof telephone booth metal shell and a manufacturing method thereof. The telephone booth metal shell is of a multilayer composite structure and comprises inner and outer galvanized steel sheet layers and a silencing and denoising layer between the inner and outer galvanized steel sheet layers, and the silencing and denoising layer comprises a silencing cotton layer with noise absorbing holes and between inner and outer noise absorbing plate layers and a noise absorbing plate, so that silencing and denoising performance of the telephone booth shell is improved greatly; by arranging a sawtooth structure, structural strength is improved, structural safety of a telephone tooth is improved, and noise absorbing effect is improved further; by arranging a waterproof layer, waterproof performance of the telephone tooth shell is improved; by arranging a protection layer, damage to inner layer structure of the telephone booth shell caused by the fact that a playful child scribbles on the telephone booth shell can be prevented.

Description

technical field [0001] The invention belongs to the technical field of telephone booth metal shells, in particular to a safe and noise-proof metal shell for telephone booths and a manufacturing method thereof. Background technique [0002] Telephone booths are public communication facilities commonly used indoors and outdoors in public, industrial and other places. Existing telephone booths are mainly open structures in terms of appearance design, with a relatively large open area, and the effect of isolating external noise is not good. The shell of the telephone booth in the prior art mainly adopts the integral molding technology of glass fiber reinforced plastic, and relies on direct isolation and blocking means to realize the local noise reduction function, but the inner wall of the glass fiber reinforced plastic material has a large noise reflection, which will produce superposition and reverberation with the voice of the caller. It affects the call quality and voice cl...

Existing telephone booths are mainly open structures in terms of shape design, with a large open area, and the effect of isolating noise from the outside is not good

The shell of the telephone booth in the prior art mainly adopts the integral molding technology of glass fiber reinforced plastic, and relies on direct isolation and blocking means to realize the local noise reduction function, but the inner wall of the glass fiber reinforced plastic material has a large noise reflection, which will produce superposition and reverberation with the voice of the caller. Affect the call quality and voice clarity of the caller, the noise reduction effect is relatively poor, reduce the call quality, and fail to meet the requirements of a good call
