該方法進一步包含提供多個通孔,該等通孔自該第一玻璃薄片之該第一表面延伸穿過該第一玻璃薄片,且穿過該黏著層,且穿過該第二玻璃薄片,至該第二玻璃薄片之該第二表面。
根據本揭露內容之額外態樣,提供一種用於聲音擴散及聲音吸收之透明或半透明結構。該結構包含:一第一玻璃薄片,其具有由一邊緣表面連接之一第一主表面及一第二主表面及小於0.8 mm的自該第一主表面至該第二主表面量測之一厚度,當在大體與該第一玻璃薄片之該第一主表面正交之一方向上檢視時,該第一玻璃薄片之該邊緣表面具有一形狀;一第二玻璃薄片,其具有由一邊緣表面連接之第一及第二主表面及小於0.8 mm的自該第一主表面至該第二主表面量測之一厚度,當在大體與該第二玻璃薄片之該第一主表面正交之一方向上檢視時,該第二玻璃薄片之該邊緣表面具有大體匹配該第一玻璃薄片之該形狀的一形狀;在該第一玻璃薄片之該第二主表面與玻璃薄片之該第一主表面之間的一透明或半透明黏著層,其以一固定組態將該玻璃薄片之該第二主表面黏附至該第二玻璃薄片之該第一主表面,使得該第一玻璃薄片之該第一主表面具有一平滑、重複上升及下降形狀;及多個通孔,其自該第一玻璃薄片之該第一表面延伸穿過該第一玻璃薄片,且穿過該黏著層,且穿過該第二玻璃薄片,至該第二玻璃薄片之該第二表面。

一般而言,本揭露內容係針對透明(或半透明)聲吸收器、擴散器及用於形成此等吸收器、擴散器之方法,特定言之,係針對透明或半透明玻璃吸收器、擴散器及其形成方法。
根據實施例且參看第1圖至第3圖,一種用於形成一透明或半透明含玻璃吸收器、擴散器之方法包含將一第一玻璃薄片20層壓至一第二玻璃薄片30,該第一玻璃薄片20具有由一邊緣表面26連接之一第一主表面22及一第二主表面24及小於0.8 mm的自該第一主表面至該第二主表面量測之一厚度,該第二玻璃薄片30具有由一邊緣表面36連接之第一主表面32及第二主表面34及小於0.8 mm的自該第一主表面至該第二主表面量測之一厚度。
當在大體與該第一玻璃薄片之第一主表面22正交之一方向上檢視時,第一玻璃薄片20之邊緣表面26具有一形狀,且當在大體與該第二玻璃薄片之第一主表面32正交之一方向上檢視時,該第二玻璃薄片30具有大體匹配該第一玻璃薄片之該形狀的一形狀。使用定位於第一玻璃薄片20之第二主表面24與第二玻璃薄片30之第一主表面32之間的一透明或半透明黏著層40將第一玻璃薄片20與第二玻璃薄片30相互層壓,從而以一固定組態將第一玻璃薄片20之第二主表面24黏附至第二玻璃薄片30之第一主表面32,使得第一玻璃薄片20之第一主表面22具有平滑、重複上升及下降形狀(諸如在第3圖中展示)。
此可藉由以下操作來達成:堆疊第一玻璃薄片20及第二玻璃薄片30與黏著層40(如第1圖中圖示)以形成一堆疊11,接著在一模具或在其他固定物(未展示)中一起形成堆疊11以強加諸如在第3圖中展示之形狀的一形狀,同時固化或以其他方式凝固黏著層40以形成如第2圖中之一經層壓結構10。替代地,在為熱塑性之一黏著層之情況中,舉例而言,黏著層可視情況經凝固,且首先以一平組態完成層壓(如在第1圖之底部處展示)以形成一平有限結構12,且可藉由以下操作使用一模具或其他固定物來改造該平的經層壓結構12:保持平的經層壓結構處於在第2圖中展示之形狀的一形狀,或逐漸使平的經層壓結構至該形狀,同時加熱經層壓結構,接著允許其冷卻,使得一旦移除模具或其他固定物,產生諸如第2圖之經層壓結構的一經層壓結構10。總之,產生一經層壓結構10,其中薄片20之上表面22具有一週期性形狀,其中一或多個井W及突起P沿著結構10交替。
該方法進一步包含提供多個通孔50(第3圖),該等通孔自該第一玻璃薄片20之該第一表面22延伸穿過該第一玻璃薄片20,且穿過該黏著層40,且穿過該第二玻璃薄片20,至該第二玻璃薄片30之該第二表面34。可藉由諸如水沖法、雷射鑽孔、雷射鑽孔加化學移除(諸如,針對玻璃薄片蝕刻,且針對黏著層氧化)之製程來提供通孔50。雖然在第1圖至第3圖中僅在第3圖中圖示通孔50,但在層壓結構10之形成之任何較早期階段,可藉由在第一玻璃薄片20及第二玻璃薄片30兩者中且在聚合物層40中提供通孔來形成通孔50。舉例而言,可同時藉由雷射鑽孔或雷射損壞及蝕刻在兩個(或更多個)堆疊之玻璃薄片中(諸如,在第一玻璃薄片20及第二玻璃薄片30中)形成孔。在平的經層壓結構12或層壓結構12之組裝後,接著將玻璃薄片20、30用作一遮罩來形成黏著層中之孔。
所得結構(其一實施例在第3圖中表示)為用於聲音擴散及聲音吸收之一透明或半透明結構,其中該結構包含:(1)一第一玻璃薄片,其具有由一邊緣表面連接之一第一主表面及一第二主表面及小於0.8 mm的自該第一主表面至該第二主表面量測之一厚度,當在大體與該第一玻璃薄片之該第一主表面正交之一方向上檢視時,該第一玻璃薄片之該邊緣表面具有一形狀;(2)一第二玻璃薄片,其具有由一邊緣表面連接之第一及第二主表面及小於0.8 mm的自該第一主表面至該第二主表面量測之一厚度,當在大體與該第二玻璃薄片之該第一主表面正交之一方向上檢視時,該第二玻璃薄片之該邊緣表面具有大體匹配該第一玻璃薄片之該形狀的一形狀;(3)在該第一玻璃薄片之該第二主表面與玻璃薄片之該第一主表面之間的一透明或半透明黏著層,其以一固定組態將該玻璃薄片之該第二主表面黏附至該第二玻璃薄片之該第一主表面,使得該第一玻璃薄片之該第一主表面具有一平滑、重複上升及下降形狀;及(4)多個通孔,其自該第一玻璃薄片之該第一表面延伸穿過該第一玻璃薄片,且穿過該黏著層,且穿過該第二玻璃薄片,至該第二玻璃薄片之該第二表面。
理想地,可使用具有更低厚度之玻璃薄片20、30,諸如,具有在自0.05 mm至0.8 mm或0.1 mm至0.75 mm或自0.1 mm至0.7 mm或自0.1 mm至0.6 mm或自0.1 mm至0.55 mm或自0.1 mm至0.5 mm之範圍內或在以上範圍中之任一者內但具有0.15 mm、0.2 mm或甚至0.3 mm之下限的一厚度之玻璃薄片。
在使用中,第3圖之結構10安裝於一架構表面附近,諸如,壁、頂板或(其他)架構面板60之表面62,如在第4圖中展示。替代地,產品自身可呈安裝於面板60之表面62上或附近的結構10之形式(如所展示),從而導致安裝之結構100。如此安裝後,在第二玻璃薄片30之第二表面34與面板60之表面62之間產生突起P,體積為V。體積V至少部分由表面34(在第1圖中展示)及62(在第4圖中展示)圍封,且可視情況由接界結構10之壁(未展示)充分圍封。通孔50與圍封之體積V合作提供一聲學吸收功能,其頻率回應可藉由調整孔50及體積V之形狀及大小來調諧。此外,表面22之上升及下降形狀之井W及突起P提供一聲學分散功能,其頻率回應可藉由調整井W及突起P之形狀及大小來調諧。因此,第3圖及/或第4圖之結構10構成一透明(或半透明)聲吸收器、擴散器。以此方式使用基於玻璃之層壓結構10,特別是具有相對薄之玻璃薄片,提供薄、輕型且合乎美學同時保持足夠硬以減少不良共振之聲吸收器、擴散器。
如在第4圖中展示,可藉由多個柱64將結構10安裝至表面62。替代地,結構10可經由一合適黏著劑(未展示)直接黏附至表面62,或可藉由其他合適方式與表面62有一段偏移或與表面62接觸地來安裝。
根據另外實施例,多個結構10可安裝於彼此附近或直接鄰近彼此安裝,諸如在第5圖中展示之組態中,從而導致包含多個安裝之結構10的一結構200。結構10或安裝之結構100或結構200可包含定位於第一玻璃薄片20之邊緣表面26處及/或第二玻璃薄片30之邊緣表面36處(或兩者)之一或多個光源70,如在第5圖之實施例中展示。根據再另外實施例,且若需要,按與其他實施例之任何組合,可包括定位於第二玻璃薄片30之第二表面34後的一光源80或一或多個光源80。根據再另外實施例且如在第6圖中展示,多個結構200可按組合安裝以形成包含具有多於一個定向之多個結構200的一結構300。
根據實施例,且按與其他實施例或態樣中之任一者的組合,技術方案1之結構,其中表面22之重複上升及下降形狀可為週期性的。替代地,表面22之重複上升及下降形狀可為非週期性的。另外,根據實施例且如上所提到,該多個通孔可包含變化大小之通孔,且另外,此外或替代地,可包含變化形狀之通孔。

根據實施例,且與其他實施例或態樣中之任一者組合,該黏著層可至少部分著色,或至少部分不透明、至少部分半透明(且不透明)或此等之組合。根據實施例,且與其他實施例或態樣中之任一者組合,至少該第一玻璃薄片可包含鋁矽酸鹽玻璃,或硼鋁矽酸鹽玻璃。

- 如請求項12所述之方法,進一步包含以下步驟:將一光源定位於該第一玻璃薄片之該邊緣表面處及/或該第二玻璃薄片之該邊緣表面處。
- 如請求項12所述之方法,進一步包含以下步驟:將一光源定位於該第二玻璃薄片之該第二表面後。
- 如請求項12所述之方法,其中層壓包含以下步驟:使得該重複上升及下降形狀為週期性之層壓。
- 如請求項12所述之方法,其中層壓包含以下步驟:使得該重複上升及下降形狀為非週期性之層壓。
- 如請求項12所述之方法,其中提供多個通孔包含以下步驟:提供變化大小之通孔。
- 如請求項12所述之方法,其中提供多個通孔包含以下步驟:提供變化形狀之通孔。
- 如請求項12所述之方法,該黏著層包含一聚合物黏著劑。
- 如請求項19所述之方法,其中該聚合物黏著劑為以下中之至少一者:一PVB(聚乙烯醇縮丁醛)材料;一低塑化劑PVB(聚乙烯醇縮丁醛)材料;一EVA(乙烯-乙酸乙烯酯共聚物)材料;具有少量金屬鹽之一乙烯/甲基丙烯酸共聚物之一組成物;具有在高達50℃之溫度下大於100 MPa之一楊氏模數的含有少量金屬鹽之一乙烯/甲基丙烯酸共聚物之一組成物;及其組合。
