Abstract
本实用新型的投影幕布，包括壳体、位于壳体内的转轴和缠绕在转轴上的幕布，所述壳体分为处于同一水平线上不连接的三节；所述幕布上均匀开有通孔，所述通孔直径在0.3mm～2.5mm之间。通过对幕布上开孔的大小及孔间距控制，使声音可穿过屏幕而不会被阻隔，进而提供了一种透声效果佳、能将图像和声音完美融合的投影幕布，可营造出色的影音环境。另外该产品兼具优良的弹性、便携性、延伸性、耐折性、可清洗性、不易沾灰性及经久耐用等性能，可广泛使用于注重影院环境效果的公共和家庭影院、商务会所及五星酒店等场所。
Description
技术领域
本实用新型涉及一种投影幕布。
背景技术
投影屏幕是投影机周边设备中最常使用的产品之一，将图像进行放大显示，可以作为演示、宣传、教学之用。作为投影装置的附件，投影幕布有多种取材，多种设置方式。在充足的的空间里，人们会安装不用收起的大型屏幕，并由于反光效应，屏幕多设置为弧形，有利于各个位置的人看清屏幕上的图像。然而，现有的音响设备只能安装在屏幕的前方，如放置在屏幕的后方或镶入墙中就会影响音质和投影效果。目前国内透声荧幕研究非常少，且有些号称是透声荧幕的产品只是简单的打孔，并没有考虑孔的大小及孔的间距控制，并且屏幕本身性能也没能得到良好的保证。
发明内容
本实用新型要解决的技术问题是提供一种具有良好投影效果的投影幕布。
为解决上述技术问题，本实用新型采用如下技术方案：包括壳体、位于壳体内的转轴和缠绕在转轴上的幕布，所述壳体分为处于同一水平线上不连接的三节；所述幕布上均匀开有通孔，所述通孔直径在0.3mm～2.5mm之间。
进一步地，三片幕布两两相交的边缘上有尼龙粘贴。
进一步地，所述壳体位于两边的两节与中间一节夹角相同并都向内倾斜。
进一步地，所述壳体内的三节转轴通过连杆连接。
进一步地，所述幕布由反射膜和遮光膜复合而成。
本实用新型的投影幕布，通过对幕布上开孔的大小及孔间距控制，使声音可穿过屏幕而不会被阻隔，进而提供了一种透声效果佳、能将图像和声音完美融合的投影幕布，可营造出色的影音环境。另外该产品兼具优良的弹性、便携性、延伸性、耐折性、可清洗性、不易沾灰性及经久耐用等性能，可广泛使用于注重影院环境效果的公共和家庭影院、商务会所及五星酒店等场所。
附图说明
图1为本实用新型投影幕布的主视图；
图2为本实用新型投影幕布的俯视图。
具体实施方式
本实施例中，参照图1和图2，所述投影幕布，包括壳体1、位于壳体1内的转轴2和缠绕在转轴2上的幕布3，所述壳体1分为处于同一水平线上不连接的三节；所述幕布3上均匀开有通孔30，所述通孔直径在0.3mm～2.5mm之间。通过对幕布上开孔的大小及孔间距控制，使声音可穿过屏幕而不会被阻隔，进而提供了一种透声效果佳、能将图像和声音完美融合的投影幕布，可营造出色的影音环境。
其中，三片幕布3两两相交的边缘上有尼龙4粘贴。所述壳体1位于两边的两节与中间一节夹角相同并都向内倾斜。所述壳体1内的三节转轴2通过连杆5连接。所述幕布3由反射膜和遮光膜(未图示)复合而成。
本实用新型的投影幕布，通过对幕布上开孔的大小及孔间距控制，使声音可穿过屏幕而不会被阻隔，进而提供了一种透声效果佳、能将图像和声音完美融合的投影幕布，可营造出色的影音环境。另外该产品兼具优良的弹性、便携性、延伸性、耐折性、可清洗性、不易沾灰性及经久耐用等性能，可广泛使用于注重影院环境效果的公共和家庭影院、商务会所及五星酒店等场所。
以上已将本实用新型做一详细说明，以上所述，仅为本实用新型之较佳实施例而已，当不能限定本实用新型实施范围，即凡依本申请范围所作均等变化与修饰，皆应仍属本实用新型涵盖范围内。
