摘要： A package design for a micromachined ultrasound transducer (MUT) utilizing curved geometry to control the presence and frequency of acoustic resonant modes is described. The approach consists of reducing in number and curving the reflecting surfaces present in the package cavity to adjust the acoustic resonant frequencies to locations outside the band of interest. The design includes a cavity characterized by a curved geometry and a MUT mounted to a side of a substrate facing the cavity with a sound emitting portion of the MUT facing an opening in the substrate. The substrate is disposed over an opening of the cavity with the substrate oriented such that the MUT located within the cavity.

摘要： An ultrasonic wave generation apparatus that includes an ultrasonic wave generation element having an inner space formed by bonding first and second vibrators so as to close off a through-hole or a groove provided in a frame body, and a connecting member that is bonded to the second vibrator supports the ultrasonic wave generation element and is electrically connected to at least one of the first and second vibrators. A ventilation hole that opens into a first side surface of the frame body and that allows the inner space to communicate with the exterior is provided in the frame body. When a direction parallel to the first main surface or the second main surface is a lengthwise direction, an outer side end portion of the ventilation hole in the lengthwise direction and an inner side end portion in the lengthwise direction of the connecting member do not match.

摘要： An easy-to-use, installation-free water leak warning device having a sturdy hollow body enclosing essential functioning elements including a power source, an amplifier, a speaker, and portions of two electrodes. The water leak warning device is preferably small in size and may be placed at potential water leak or flooding spots. The essential functioning elements are operatively connected with conductive material so that when leaked water flows to where the device is located, an audible signal can be emitted to alert the user of the device to prevent further leakage and mitigate any damage.
