摘要： A sensor attachment structure includes a sound receiving member for receiving an ultrasound, an ultrasonic sensor attached to the sound receiving member. The ultrasonic sensor includes a semiconductor substrate having first and second surfaces opposite to each other and a substrate recess portion recessed from the first surface of the semiconductor substrate so as to form a membrane in the semiconductor substrate. Furthermore, a cap member is located between the sound receiving member and the semiconductor substrate to cover the second surface of the semiconductor substrate. In addition, the cap member has a first surface bonded to the sound receiving member, and a second surface that is bonded to the second surface of the semiconductor substrate at an outer periphery section of the membrane while having a gap between the cap member and the membrane.

摘要： An ultrasonic sensor includes a plurality of vibrating parts, a plurality of receiving elements, and a waveguide. Each of the vibrating parts vibrates when a corresponding ultrasonic wave reflected by a detection object is transmitted thereto, and receives the ultrasonic wave. Each of the elements includes corresponding one of the vibrating parts and detects the object using the corresponding ultrasonic wave. The ultrasonic wave is transmitted through the waveguide to each of the elements. The waveguide includes a first opening facing the object, a second opening, and a reflecting surface that reflects the ultrasonic wave in a direction to each of the vibrating parts. The ultrasonic wave enters through the first opening. The second opening is not viewable from the first opening. The second opening holds the elements such that the each of the vibrating parts faces a direction where the each of the vibrating parts receives the ultrasonic wave.

摘要： An ultrasonic sensor includes an ultrasonic detecting element, an acoustic matching member, and an oscillation damping member. The ultrasonic detecting element detects an ultrasonic wave. The acoustic matching member has a receiving surface that is adapted on a side of the certain object to be exposed to a space, in which the detected body exists. The receiving surface receives the ultrasonic wave reflected by the detected body. The acoustic matching member is made of a material having an acoustic impedance larger than that of air and smaller than that of the ultrasonic detecting element. The oscillation damping member is disposed between an attachment portion and the acoustic matching member. The attachment portion is adapted for attaching the ultrasonic sensor to the certain object. The oscillation damping member damps transmission of oscillation from the certain object to the acoustic matching member.

摘要： An ultrasonic sensor includes a transmitting device, a receiving device, and a circuit device. The circuit device determines that the receiving device receives an ultrasonic wave reflected from an object, when an output voltage of the receiving device is equal to or greater than a first threshold. The circuit device includes a humidity detection section configured to detect an ambient humidity of the transmitting and receiving devices and a threshold adjustment section configured to calculate, based on the detected ambient humidity, a sound pressure of the ultrasonic wave that is received by the receiving device after propagating over a round-trip distance between the ultrasonic sensor and the object. The threshold adjustment section reduces the first threshold, when the output voltage corresponding to the calculated sound pressure is less than a second threshold that is greater the first threshold.
