Integrated air pressure vent

The invention relates to an integrated pneumatic vent. Improved acoustic devices include waterproof ventilation across various surfaces within acoustic devices such as speakers and microphones. Surfaces, such as acoustic diaphragms, covers for resonant chambers and covers for external ports of acoustic transducers, may include design features that create or enhance gas permeable and water impermeable properties. Such design features include, for example, a series of holes in the vented surface. 本公开涉及集成气压通气口。改进的声学设备包括跨声学设备诸如扬声器和麦克风内的各种表面的防水通气。表面诸如声学隔膜、用于共振室的覆盖件和用于声学换能器的外部端口的覆盖件可包括产生或增强气体可渗透属性和水不可渗透属性的设计特征。此类设计特征包括例如在该通气式表面中的一系列孔。
