本文描述了一种不配备任何电子设备的机械驱动微哨的设计和检测。当被激活时，微型哨子会在可听范围之上产生超声波音调。在近距离记录中的一组三个或更多的麦克风该音调和哨声的位置是根据声音信号到达麦克风的时间的差值来计算的。在实验中，在2米×2米的区域内测量了哨声的位置，精度低于10厘米。此外，微哨还被用作遥控器，如房间照明或空调的开关。微哨是通过超声波热压热压热塑性塑料箔以低成本制造的，其总尺寸约为1厘米。文中还介绍了如何克服偶然产生的超声波噪声、哨声激励力变化引起的频率漂移、区分不同哨声信号等障碍。
This paper describes the design and detection of mechanically actuated micro whistles not equipped with any electronics. When actuated, the micro whistle generates an ultrasonic tone above the audible range. A set of three or more microphones in the near record this tone and the position of the whistle is calculated from the differences of the arrival times of the acoustic signals at the microphones. In experiments the positions of whistles were measured in a 2 m × 2 m area with an accuracy of less than 10 cm. Besides this, micro whistles have been employed as remote controls such as switches for room light or air conditioning.The micro whistles have been fabricated by ultrasonic hot embossing of thermoplastic foils at low-cost and their overall size is approximately 1 cm. The paper also describes how to overcome obstacles such as accidentally generated ultrasonic noise, frequency shifts due to changing activation forces of the whistles, and distinguishing the signals of different whistles.
