实施例1
图2示出了根据本申请一个实施例的一种耳罩的截面图。如图2所示，本申请耳罩包括耳罩气囊1、耳罩海绵2和耳罩皮革3。耳罩海绵2包覆在耳罩气囊1的外表面，耳罩皮革3包覆在耳罩海绵2的外表面。其中，耳罩气囊1包括有至少一个中空的封闭气囊，具有一定的支撑力。而且，耳罩气囊1 采用软胶材质，保证了耳罩的整体柔软度，提升了用户佩戴体验。
其中，软胶材质是指具有一定延展性和柔韧性的软性材质，包括但不限于硅胶、橡胶、软质聚氯乙烯(Polyvinyl chloride，PVC)、乙烯-醋酸乙烯共聚物(ethylene-vinyl acetate copolymer，EVA)、聚烯烃热塑性弹性体(polyolefin thermoplastic elastomer，POE)、热塑性弹性体(Thermoplastic Elastomer，TPE)、聚丙烯(polypropylene，PP)等材质。
外界噪声在进入耳罩内部时，需要依次经过耳罩皮革3、耳罩海绵2，进入耳罩气囊1，由于耳罩气囊1是中空的封闭气囊，噪声还需要再依次穿过耳罩气囊1、耳罩海绵2、耳罩皮革3，才进入耳罩内部，传入人耳。与传统耳罩仅经过耳罩皮革3’和耳罩海绵2’两种介质相比，通过增加耳罩气囊1，增加了噪声的传导介质，使噪声通过不同介质的传导被不断地减弱，增强了耳罩的被动降噪能力，提升了用户体验。而且该耳罩气囊1包括有至少一个中空的封闭气囊，相较于海绵材质，为耳罩提供了更强的支撑力，能够替代传统的耳罩海绵支撑。
综上所述，本申请通过增加中空封闭的耳罩气囊1，使耳罩具有了更好的降噪效果和支撑效果。
实施例2
本申请的耳罩气囊1可以为整段式封闭气囊。其中，整段式封闭气囊内包括零个或至少一个气囊隔断。
图3至图5示意性地示出了本申请整段式封闭气囊的多个实施例，其中，图3示出了根据本申请一个实施例的一种整段式封闭气囊的外观图；图4示出了根据本申请一个实施例的一种包括零个气囊隔断整段式封闭气囊的剖面图，图5示出了根据本申请一个实施例的一种包括多个气囊隔断的整段式封闭气囊的剖面图和完整图。
如图4所示，整段式封闭气囊不包括气囊隔断，气囊内部空间1-2为一个完整的封闭空间。
如图5所示，整段式封闭气囊包括5个气囊隔断1-3，各气囊隔断1-3之间互相独立，整个环形的气囊内部空间1-2被分割为数个独立的小气囊。通过将环形的整个耳罩气囊分割为数个独立的小气囊，一方面，在某个小气囊漏气的情况下，其他完好的小气囊仍然可以为整个耳罩气囊提供支撑力；另一 方面，气囊隔断1-3也可以增强整段式封闭气囊的内部支撑力。
需要说明的是，图5仅是对整段式封闭气囊进行举例说明，而不是对本申请的限制，整段式封闭气囊内可以设置任意数量的气囊隔断1-3。
实施例3
本申请的耳罩气囊1可以为多段式封闭气囊，其中，多段式封闭气囊中的每段气囊互相连通或互相独立。
图6至图8示意性地示出了本申请多段式封闭气囊的多个实施例，其中，图6示出了根据本申请一个实施例的一种多段式封闭气囊的剖面图(a)和外观图(b)，图7示出了根据本申请一个实施例的另一种多段式封闭气囊的剖面图(a)和外观图(b)，图8示出了根据本申请一个实施例的又一种多段式封闭气囊的剖面图(a)和外观图(b)。
如图6至图8所示，整个环形气囊可包括任意数量个的气囊间隔1-4，例如4个、2个或1个等，根据需要设计这些气囊间隔1-4的位置和长度。其中，多段式封闭气囊中的每段气囊可以互相连通，如图6所示，每段气囊的两端与气囊间隔1-4连通，从而通过气囊间隔1-4将四段气囊互相连通。多段式封闭气囊中的每段气囊也可以互为独立的气囊，如图7和图8所示，每段气囊的两端封闭，每段气囊均为一个独立的气囊，气囊间隔1-4将每段独立的气囊连接，但与每段气囊互不连通。
本实施例中，通过气囊间隔1-4将环形的整个耳罩气囊分割为数个独立的小气囊，在某个小气囊漏气的情况下，其他完好的小气囊仍然可以为整个耳罩气囊提供支撑力，延长了耳罩的使用寿命。
优选地，多段式封闭气囊中的每段气囊无论是在互相连通或互相独立的情况下，在每个气囊间隔1-4处均使用海绵进行填充，用于填充的海绵可以与包裹在耳罩气囊外面的耳罩海绵2一体制作后填充，也可以独立填充于该气囊间隔1-4的空间内。在气囊间隔1-4处填充海绵，可以增强相邻段小气囊彼此间的支撑力。
本实施例中的耳罩气囊的气囊壁厚1-1可设计为不同的厚度，以满足用户的不同需求，例如设计为较薄的壁厚，可以增大耳罩与用户耳朵之间的空间，增强音质；设计为较厚的壁厚，可以增强耳罩的支撑力，使耳罩不易变形且更加耐用。
需要说明的是，上述仅是对多段式封闭气囊进行举例说明，而不是对本申请的限制，多段式封闭气囊可以采用各种形式的任意数量的分段气囊。
实施例4
在耳罩气囊为整段式封闭气囊或互相连通的多段式封闭气囊情况下，本申请的耳罩气囊1可以通过一体装配形成。
图9至图11示意性地示出了本申请耳罩气囊一体装配的一个实施例，其中，图9示出了根据本申请一个实施例的一种一体装配的耳罩气囊的展开图，图10示出了根据本申请一个实施例的一种一体装配的耳罩气囊的装配效果截面图，图11示出了根据本申请一个实施例的一种一体装配的耳罩气囊的装配效果外观图。
如图9所示，该耳罩气囊1在初始状态呈中空条状，一端设置有气囊凹陷1-5，另一端设置有气囊凸起1-6，两端通过对接装配并粘合后形成封闭的耳罩气囊1，装配效果如图10和图11所示。
图12示出了根据本申请一个实施例的一种耳罩的分解图；图13示出了图12所示耳罩的分解截面图。如图12和图13所示，本申请的耳罩还包括气囊底座4，该气囊底座设置在耳罩气囊1的底部，用于增强耳罩气囊1底部的支撑力。气囊底座4的材质不限，优选采用硬质材料，这样能够保证耳罩的整体支撑力。
优选地，参见图9，耳罩气囊1的内壁上设置有多条加强筋1-7，多条加强筋1-7均匀分布在耳罩气囊的内壁上，用于增强耳罩气囊1内壁的支撑力。
图14示出了根据本申请一个实施例的一种气囊底座图。在一体装配耳罩气囊的情况下，如图14所示，气囊底座4的里侧凸台上设置有多个加强筋卡位4-1，通过多条加强筋1-7与多个加强筋卡位4-1的相互卡合，将气囊底座4设置在耳罩气囊1的底部，用于增强耳罩气囊1底部的支撑力。
优选地，多条加强筋1-7均匀分布在耳罩气囊1的内壁上，多个加强筋卡位4-1均匀分布在气囊底座4上，且多条加强筋1-7与多个加强筋卡位4-1在设置数量和设置位置上相互匹配，以均衡耳罩气囊1的内壁及底部的支撑力。
实施例5
本申请的耳罩气囊1还可以通过分体装配形成。
图15至图16示意性地示出了本申请分体装配的耳罩气囊的一个实施例。 其中，图15示出了根据本申请一个实施例的另一种耳罩的分解截面图；图16示出了图15所示耳罩的装配效果截面图。
如图15所示，耳罩气囊1在分体装配的情况下，耳罩气囊1包括耳罩气囊上件1-8和耳罩气囊下件1-9。耳罩气囊上件1-8设置有骨架结构，可以为耳罩气囊提供一定的支撑力。耳罩气囊上件1-8的底部设置有卡口1-8-1，耳罩气囊下件1-9上表面设置有凸台1-9-1，耳罩气囊上件的底部卡口1-8-1与耳罩气囊下件上表面的凸台1-9-1通过卡和装配形成耳罩气囊1。并且，气囊底座4的里侧设置有耳罩气囊下件1-9的安装槽4-3，通过将耳罩气囊下件1-9装配并粘合在安装槽4-3内，将气囊底座4设置在耳罩气囊1的底部，装配效果截面图参见图16。
实施例6
需要说明的是，在满足相同支撑力与适当舒适性的情况下，传统耳罩内的耳罩海绵2’的截面根部宽度与截面面积要大于本申请的耳罩的根部宽度与截面面积，故传统耳罩与本申请的耳罩相比，耳朵与发声单元之间的前音腔较小，音质较差。
参见图14至图16，气囊底座4还用于容纳并收紧耳罩海绵，例如将包裹耳罩气囊1的耳罩海绵2收紧在的外侧平台4-2内，以缩小耳罩根部的最大直径。图17示出了本申请耳罩与传统耳罩在收缩空间差异上的示意图，其中阴影部分示意的是二者的收缩空间差异部分5。如图17所示，相较于传统耳罩，在满足相同支撑力与适当舒适性的情况下，本申请耳罩在耳罩根部可以收缩的更小，耳罩的根部宽度与截面面积更小，从而增大了耳机发声单元与耳朵之间的前音腔，增强了音质。
实施例7
本实施例公开了一种头戴式耳机，该头戴式耳机使用上述实施例1-6所述的耳罩。头戴式耳机通过采用上述耳罩，相较于现有的头戴式耳机，增强了耳机被动降噪能力，提升了音质，稳定性更强，提高了用户体验。
综上所述，本申请的耳罩通过增加耳罩气囊，增加了噪声的传导介质，使噪声通过不同介质的传导被不断地减弱，增强了耳罩的被动降噪能力，提升了用户体验。该耳罩气囊包括有至少一个中空的封闭气囊，为耳罩提供了更稳定的支撑力；并且相较于传统耳罩，本申请的耳罩在耳罩根部可以收缩 的更小，可以在外观轮廓尺寸不发生较大变化的情况下增大耳机发声单元与耳朵之间的空间，从而增强音质。
以上所述，仅为本申请的具体实施方式，在本申请的上述教导下，本领域技术人员可以在上述实施例的基础上进行其他的改进或变形。本领域技术人员应该明白，上述的具体描述只是更好的解释本申请的目的，本申请的保护范围应以权利要求的保护范围为准。
