摘要： Disclosed herein is an ultrasonic sensor having a water-repellent function. More specifically, disclosed is an ultrasonic sensor having a sound-emitting opening in the upper portion of an external housing, wherein a support having a water-repellent film formed thereon is attached to the upper portion of the external housing, which includes the sound-emitting opening. According to the disclosed invention, a substantially closed ultrasonic sensor is realized by attaching the support, having the water-repellent film formed thereon, to an open ultrasonic sensor. Specifically, if the ultrasonic sensor having a water-repellent function is used, characteristics such as sensitivity and directivity of the open ultrasonic sensor, which has a high degree of freedom of design and high energy conversion efficiency, can be maintained at suitable levels and, at the same time, liquid such as water or oil can be prevented from penetrating into the ultrasonic sensor. Thus, the disclosed ultrasonic sensor having a water-repellent function can be stably used even in an outdoor environment where it is difficult to use an open ultrasonic sensor. Specifically, the disclosed ultrasonic sensor can be applied to range finders, invasion-preventing systems, intelligent robots, high-tech electronic industrial products, etc.
摘要翻译：这里公开了具有防水功能的超声波传感器。更具体地，公开了一种在外壳的上部具有发声口的超声波传感器，其中形成有防水膜的支撑体附接到外壳的上部，该外壳包括声音 - 排放开口。根据所公开的发明，通过将其上形成有防水膜的支撑件附接到开放式超声波传感器来实现基本上闭合的超声波传感器。具体地，如果使用具有防水功能的超声波传感器，则可以将具有高设计自由度和高能量转换效率的开放式超声波传感器的灵敏度和方向性等特性保持在适当的水平，同时可以防止诸如水或油的液体渗入超声波传感器。因此，即使在难以使用开放式超声波传感器的室外环境中，也能够稳定地使用所公开的具有防水功能的超声波传感器。具体来说，所公开的超声波传感器可以应用于测距仪，防侵入系统，智能机器人，高科技电子工业产品等。
