摘要： The invention relates to an electroacoustic converter (1) for detecting the surroundings of a transportation means. The electroacoustic converter comprises a membrane (4) and a first motor (3). The membrane (4) is designed to vibrate in a preferred direction (P1), and the motor (3) has a stack of separately contacted elementary motors which are designed to change the length of the stack in a drive direction (P2) in response to an acoustic signal impinging on the membrane (4) and/or an electric signal applied to the first motor (3), wherein the drive direction (P2) is oriented differently than the preferred direction (P1).

摘要： In an inner bottom surface of a case (31), a substantially oblong recess (40) having a long axis and a short axis forms a vibration area (VA). A piezoelectric element (37) is bonded to the center of the recess (40). On the opposite sides of the vibration area (VA), vibration suppression areas (SVA) thicker than the vibration area (VA) are disposed. A side portion of the case (31) is formed to be thin over the entire circumference. A reinforcing member (41) higher in rigidity than the case (31) is bonded to upper portions of the vibration suppression areas (SVA). The reinforcing member (41) has a bottom surface substantially equal to the shape of the vibration suppression areas (SVA), and has a predetermined height. A gap between the reinforcing member (41) and an inner side surface of the case (31) is also filled with a filling member (35).

摘要： An ultrasonic transducer (1) includes a substrate (2), a supporting film (5), and a piezoelectric element (7). The substrate (2) includes an opening (21). The supporting film (5) is configured on the substrate (2) to cover the opening (21). The piezoelectric element (7) is configured at a part of the supporting film (5). The part overlaps with the opening (21) in a planar view in a thickness direction of the substrate (2). A thickness of the part of at a center of gravity in the planar view is smaller than a thickness of an outer edge portion of the part. The outer edge portion is closer to the substrate (2) than the center to the substrate (2).

摘要： An ultrasonic piezoelectric transducer device includes a transducer array consisting of an array of vibrating elements, and a base to which the array of vibrating elements in the transducer array are attached. The base include integrated electrical interconnects for carrying driving signals and sensed signals between the vibrating elements and an external control circuit. The base can be an ASIC wafer that includes integrated circuitry for controlling the driving and processing the sensed signals. The interconnects and control circuits in the base fit substantially within an area below the array of multiple vibrating elements.
