摘要： Described herein is a method for producing a microstructured air-permeable environmental barrier membrane (110), the method comprising steps of providing a substrate (120), and structuring a through hole (130) into the substrate (120), the through hole (130) extending fully through the substrate (120) between two opposite surfaces (121, 122) of the substrate (120), leaving the through hole (130) uncovered and depositing one or more nanofibers (111) onto at least one of the two opposite substrate surfaces (121, 122) by applying at least one of an electrospinning or blowspinning method, such that the spun nanofibers (111) combine to a network of nanofibers that forms a free-standing and mechanically compliant nanofibrous membrane (110) covering the previously uncovered through hole (130).

摘要： The waterproof sound-permeable membrane of the present disclosure is a waterproof sound-permeable membrane adapted to permit passage of sound and prevent ingress of water. The air permeability of the waterproof sound-permeable membrane (12), as expressed by Gurley number, is 20 seconds/100 mL or more. The water entry pressure of the waterproof sound-permeable membrane (12) is 500 kPa or more. When a tensile strength at break of the waterproof sound-permeable membrane (12) in a MD direction is denoted by T1 and a tensile strength at break of the waterproof sound-permeable membrane (12) in a TD direction orthogonal to the MD direction is denoted by T2, a strength ratio (T1/T2) is in a range of 0.5 to 2.0.

摘要： The sound-permeable membrane of the present invention is adapted, when placed over an opening for directing sound to or from a sound transducer, to prevent entry of foreign matters into the sound transducer through the opening while permitting passage of sound, the sound-permeable membrane including a non-porous film or a multilayer membrane including the non-porous film. The non-porous film is formed of oriented polytetrafluoroethylene. This sound-permeable membrane has an unconventional configuration and exhibits various excellent properties. At least one principal surface of the non-porous film may have a region subjected to a surface modification treatment.

摘要： An acoustic device for forming a wall of sound underwater. Walls of sound are useful in water for guiding fish away from areas. Hitherto, systems have used bubbles of water to facilitate the speed of travel of the sound. Those systems have suffered from the ability to maintain a consistent wall of bubbles and have often been inefficient.
The present invention seeks to provide an acoustic device for forming a wall of sound underwater and comprises a transducer connected to an acoustic waveguide. The waveguide comprises one or more projections, whereby sound generated by the transducer travels along the projection or projections to form the wall of sound.
The waveguide may typically comprise compressible projections formed from neoprene. These projections are arranged in a fan or frond shape. In addition or alternatively, the projections may be laminar. The projections could be of different lengths. The location, arrangement and lengths of the projections are all suited to the underwater location to maximise the effectiveness of the wall of sound.
摘要翻译：一种用于在水下形成声音墙的声学装置。声音的墙在水中用于引导鱼远离区域。迄今为止，系统已经使用水泡来促进声音的传播速度。这些系统受到保持恒定泡沫壁的能力的影响，并且往往效率低下。本发明试图提供一种用于在水下形成声音墙壁的声学装置，并且包括连接到声波导的换能器。波导包括一个或多个突起，由此换能器产生的声音沿着一个或多个突起行进以形成声音的壁。波导通常可以包括由氯丁橡胶形成的可压缩突起。这些投影以扇形或叶状排列。另外或可选地，突起可以是层状的。投影可以具有不同的长度。投影的位置，排列和长度都适合于水下位置，以最大限度地提高声音墙的效果。

摘要： A speaker or microphone module includes an acoustic membrane and at least one pressure vent. The pressure vent equalizes barometric pressure on a first side of the acoustic membrane with barometric pressure on a second side of the acoustic membrane. Further, the pressure vent is located in an acoustic path of the speaker or microphone module. In this way, differences between barometric pressures on the different sides of the acoustic membrane may not hinder movement of the acoustic membrane. In one or more implementations, the pressure vent may be acoustically opaque. As the pressure vent is located in the acoustic path of the speaker or microphone module, being acoustically opaque may ensure that the pressure vent itself does not interfere with the operation of the speaker or microphone module.
摘要翻译：扬声器或麦克风模块包括声膜和至少一个压力通风口。压力通风口在声膜的第二侧使大气压力在声膜的第一侧平衡大气压力。此外，压力通风口位于扬声器或麦克风模块的声学路径中。以这种方式，声膜不同侧的气压之间的差异可能不会妨碍声膜的运动。在一个或多个实施方案中，压力通风口可以是声学不透明的。当压力通风口位于扬声器或麦克风模块的声学路径中时，声学不透明可以确保压力通风口本身不会干扰扬声器或麦克风模块的操作。

摘要： A waterproof sound-transmitting membrane of the present disclosure includes: a non-porous resin film having formed therein a plurality of through holes extending through a thickness of the non-porous resin film; and a liquid-repellent layer formed on a principal surface of the resin film and having openings at positions corresponding to positions of the plurality of through holes. The through holes have a diameter of 4.0 µm or more and 12.0 µm or less, and the waterproof sound-transmitting membrane has a through-thickness air permeability of 2.0 cm 3 /(cm 2 €¢ second) or more and 50 cm 3 /(cm 2 €¢ second) or less in terms of Frazier number as measured according to JIS L 1096. With this waterproof sound-transmitting membrane placed over an opening of a housing of an electronic device or the like, entry of water into the housing from outside can be prevented, in addition to which the characteristics of sound transmitted through the membrane can be kept even when the membrane has a reduced effective area.
