Abstract

The invention discloses a compound sound insulation wooden door which is formed by compounding an inner wood material layer, an outer wood material layer and an intermediate acoustic material layer, and the faces, connected to the acoustic material layer, of the inner wood material layer and the outer wood material layer are of acoustic structures with round holes and slotted holes so that the effects of sound insulation and noise reduction are achieved; in addition, in regard to the material selection, the inner wood material layer and the outer wood material layer are made from Korean pine with a good sound insulation effect and manchurian ash with high mechanical strength, and the acoustic material layer is made from special light acoustic materials; on the premise of obtaining the good sound insulation effect, the overall weight of the wooden door is reduced effectively; the sound insulation effect of the wooden door is improved effectively through the combined effect of the acoustic structure design and the acoustic materials, and the weight is rational; and the compound sound insulation wooden door can be widely applied to different kinds of occasions, and the practical value is high.

Description

technical field [0001] The invention relates to the field of wooden doors, in particular to a composite sound-insulating wooden door. Background technique [0002] Now the wooden doors in the decoration market are mostly solid wood doors or wooden composite doors. Although they have the advantages of being beautiful and generous, the sound insulation effect is poor. It is used in offices, conference rooms, theaters and other places with high requirements for sound insulation performance, which limits the scope of application of these wooden doors. [0003] Existing sound-absorbing wooden doors generally place sound-absorbing materials between two or more layers of wood boards or set wooden materials with acoustic structure design to achieve sound-insulating effects. Excessive use of sound-absorbing materials will increase the weight of wooden doors. Shortcomings, However, wooden materials for acoustic structure design usually have the disadvantages of insufficient sound abs...
