Abstract
A sound insulation board for language labs comprises a back cavity veneering layer, a base material layer, a polyvinyl chloride (PVC) plastic veneering layer, a sound absorbing hole and a villus layer, wherein the sound insulation board for language labs is in an interlayer structure, the base material layer is arranged between the back cavity veneering layer and the PVC plastic veneering layer, and is composed of columns in a regular six face hole shape, the villus layer is attached to the inside of the six face hole, and the sound absorbing hole is arranged on the PVC plastic veneering layer. The sound insulation board for language labs has the advantages of being simple in structure, light in weight, high in intensity, attractive in appearance, low in price, good in sound absorbing performance, and capable of effectively eliminating sound wave resonance; when sound waves of sound sources enter the sound absorbing hole, the sound waves are absorbed on the villus, the sound waves do not rebound, and the sound absorbing and damping effects are well provided.
Description
Technical field
The utility model relates to voice classroom articles for use, relates in particular to speech room and uses sound insulating panel.
Background technology
Having relatively high expectations to its internal environment in voice training or when test in the voice classroom, especially the sound insulation materials in the voice classroom is had relatively high expectations, and good sound absorption qualities arranged, and can eliminate the acoustic resonance phenomenon effectively, but also in light weight, requirement such as intensity is big; The inner damping material in present voice classroom is mostly sticked on by materials such as the gypsum plank of being with micropore or coarse sand granules and constitutes on the interior walls, and this quality of materials is heavy, intensity difference, and outward appearance and sound-absorbing effect do not reach requirement yet.Other commercially available sound insulation materialss cost an arm and a leg at present, and are not easy to construction.
The utility model content
The purpose of the utility model is, overcomes the weak point of prior art, provides a kind of simple in structure, in light weight, and intensity is high, good looking appearance, and low-cost speech room is used sound insulating panel.
The described speech room of the utility model is used sound insulating panel; Include back of the body chamber overlay coating, substrate layer, PVC plastic facing layer, sound absorption hole and tapetum; Said speech room uses sound insulating panel to be sandwich, is being provided with substrate layer on the overlay coating of said back of the body chamber and between the PVC plastic facing layer, and said substrate layer is made up of positive six face shape cylinders; The sticking tapetum that is provided with in the inside of six through holes, said PVC plastic facing layer is provided with the sound absorption hole.
The utility model is simple in structure, and is in light weight, and intensity is high; Good looking appearance, low price, this speech room has good sound absorption qualities with sound insulating panel; Can eliminate acoustic resonance effectively, after the sound wave of sound source got into the sound absorption hole, sound wave was absorbed on the fine hair; Sound wave does not rebound, and plays good sound absorption damping action.
Description of drawings
Accompanying drawing 1 is the overall structure sketch map of the said speech room of the utility model with sound insulating panel; Accompanying drawing 2 is the speech room of the utility model substrate layer structural representations with sound insulating panel.Overlay coating 2-substrate layer 3-PVC plastic facing layer 4-sound absorption hole, 1-back of the body chamber 5-tapetum.
The specific embodiment
Existing with reference to accompanying drawing 1 and accompanying drawing 2; Explain as follows in conjunction with embodiment: the described speech room of the utility model is used sound insulating panel; Include back of the body chamber overlay coating 1, substrate layer 2, PVC plastic facing layer 3, sound absorption hole 4 and tapetum 5; Said speech room uses sound insulating panel to be sandwich, is being provided with substrate layer 2 on the said back of the body chamber overlay coating 1 and between the PVC plastic facing layer 3, and said substrate layer 2 is made up of positive six face shape cylinders; The sticking tapetum 5 that is provided with in the inside of six through holes, said PVC plastic facing layer 3 is provided with sound absorption hole 4.The utility model is simple in structure, and is in light weight, and intensity is high; Good looking appearance, low price, this speech room has good sound absorption qualities with sound insulating panel; Can eliminate acoustic resonance effectively, after the sound wave of sound source got into the sound absorption hole, sound wave was absorbed on the fine hair; Sound wave does not rebound, and plays good sound absorption damping action.
