    • The sealing earplug is characterised in that the sealing plug (1) comprises an engagement anatomical head (2) with the shape moulded and adapted to the shape of the 5 pinna (12), provided with an external end of an unidirectional pneumatic valve (5) and with an internal duct (6) that fluidly connects said valve (5) with a tubular appendix (3) provided to be inserted, at least partially, inside the external ear duct, coated with a 10 thin cover (41) made from an elastomeric material and provided with holes (8) that communicate the internal space of the appendix with the internal face of the cover (41), so that when air is blown through the valve (5) with said inflating means, said cover (41) is inflated to 15 constitute said sealing globule (4), which adapts its shape to the particular shape of the external ear duct (9).
    • 密封耳塞的特征在于,密封塞(1)包括接合解剖头部(2),其形状模制并适于5针(12)的形状,其具有单向气动阀(5)的外端 )和内部管道(6),其将所述阀(5)与管状附件(3)流体连接,所述管状附件(3)至少部分地设置在所述外部耳道内部,所述管状附件(3)涂覆有由10个薄盖(41)制成的10个薄盖 弹性体材料,并且设置有将附件的内部空间与盖(41)的内表面连通的孔(8),使得当空气通过所述充气装置吹过阀(5)时,所述盖(41 )充气到15构成所述密封球(4),其适应其形状与外耳道(9)的特定形状。

    • An earphone device comprises an inner casing enclosing one or more miniature drive units, and a movable cap or outer casing that moves relative to the inner casing. The inner casing has an extension member, such as a hollow post, terminating in an acoustic output port. A compressible foam bulb at least partially surrounds the extension member, and is decompressed and compressed by actuation of an adjustable member. The adjustable member may take the form, for example, of a pivoting lever, a helical cam, or a push-rod mechanism, among other things. A flange may be disposed around the periphery of the movable cap, in order to provide a seal surrounding the ear canal region.. The compressible material may be gripped by the hollow extension member, and abut the movable cap or flange. Through actuation of the adjustable memer, the compresible material may be decompressed and thus elongated for insertion into the wearer's ear, and may be compressed and thus widened or expanded to form an adequate seal with the wearer's ear canal region.
    • 一种耳机装置包括内部壳体和相对于内部壳体移动的可移动盖或外壳,所述内壳包围一个或多个微型驱动单元。 内壳具有终止于声输出端口的延伸构件,例如中空柱。 可压缩的泡沫球至少部分地围绕延伸构件,并且通过致动可调节构件而被减压和压缩。 除了别的之外,可调节构件可以采取例如枢转杆,螺旋凸轮或推杆机构的形式。 可以围绕可动帽的周边设置凸缘,以便提供围绕耳道区域的密封。可压缩材料可以被中空延伸构件夹持并且邻接可动帽或凸缘。 通过启动可调节的调节器,可压缩材料可以被减压并且因此被拉长以便插入到佩戴者的耳朵中,并且可以被压缩并且因此被加宽或扩展以与佩戴者的耳道区域形成足够的密封。
