摘要： Illustrative embodiments enable a MEMS transducer to quickly recover from, acoustic overload events by quickly resetting signal processing circuitry downstream from a MEMS transducer. An acoustic overload sensor detects occurrence of an acoustic overload event, and triggers a reset circuit to operate a set of switches to rapidly drain charge from a corresponding set of capacitances within the transducer, or within the signal processing circuitry, thereby resetting the signal processing circuitry more rapidly than would occur if said transducer or circuitry were allowed to recover on its own.

The suspension member forms a cantilever beam comprising a static end, a moveable end and a virtual hinge line arranged in between, wherein at least part of the moveable mass is secured to the cantilever beam between the virtual hinge line and the moveable end, and wherein the one or more piezo electric layers are secured to the cantilever beam in a manner so that the one or more piezo electric layers intersect the virtual hinge line. The present invention further relates to a hearing device comprising a vibration sensor and use of the vibration sensor for voice recognition in a hearing device.

摘要： In a vibration sensor, both ends of a vibration beam are fixed on a base, and a middle portion is suspended in a cavity and generates deformation in response to external vibrational excitation. The portions, suspended in the cavity, of a plurality of vibration beams have different dimensions by changing a structure and a dimension of the cavity and a dimension and a position of each vibration beam, so that different vibration beams have different natural frequencies, and resonance peaks of different frequencies are generated under vibrational excitation, forming a wider frequency response range. In addition, a vibration signal selected by the vibration sensor is a vibration signal within a preset range near the resonance peak, and the sensitivity is relatively high. A microphone having the vibration sensor is also provided.

摘要： An array of micromachined ultrasonic transducers (MUTs). The array has first and second rows, the MUTs in the first row being equally spaced by a horizontal pitch in a horizontal direction, the MUTs in the second row being equally spaced by the horizontal pitch in the horizontal direction. The MUTs in the second row are shifted along the horizontal direction by a first horizontal distance relative to the MUTs in the first row and shifted along a vertical direction by a first vertical distance relative to the MUTs in the first row. The first horizontal distance is greater than zero and less than the horizontal pitch. The first vertical distance ranges from one tenth of a horizontal width of a MUT to a half of a vertical height of a MUT.
