Abstract: An apparatus of the disclosure is directed to an elongated polygon transducer membrane having a perimeter that includes a plurality of edges and a plurality of vertices. The elongated polygon transducer membrane may be fixed to a support structure at or around a plurality of the vertices and not fixed to the support structure at more than 50% of the perimeter. The apparatus of the disclosure may be an elongated hexagon transducer membrane having a perimeter comprising six edges and six vertices. The elongated hexagon transducer membrane may be fixed to a support structure at or around two vertices of the six vertices that are most distant from each other and not fixed at the other vertices or the edges of the perimeter.

Abstract: Systems and techniques are provided for a piezoelectric transducer. A base plate includes a first electrical contact and a second electrical contact. A transduction element is mounted directly on the base plate and electrically connected to the first electrical contact. A spacer includes a via. The via includes electrically conductive material. The spacer is mounted on the base plate around the transduction element and the electrically conductive material of the via is electrically connected to the second electrical contact. A diaphragm is mounted on the spacer and on the transduction element.

Abstract: An apparatus of the disclosure is directed to an elongated polygon-shaped transducer elastic layer having a first plurality of edges, a first plurality of vertices, and a first electrical connection at one of the first plurality of vertices. The apparatus includes an elongated polygon-shaped electrically active material layer having a second plurality of edges, a second plurality of vertices, and a second electrical connection at one of the second plurality of vertices, where the elongated polygon-shaped electrically active material layer is disposed on the elongated polygon-shaped transducer elastic layer to transform electrical excitation into a high-frequency vibration to produce ultrasonic acoustic emissions or transform received high-frequency acoustic vibration into electrical signals. The elongated polygon-shaped transducer elastic layer and the elongated polygon-shaped electrically active material layer may be hexagonal.

Abstract: An apparatus of the disclosure is directed to conical structure of an ultrasonic transducer. The conical structure may have a first circumference and a second circumference, respectively located at opposite ends of the conical structure, where the first circumference has a greater length than the second circumference. An angle may be formed between a plane including the second circumference and a surface of the conical structure, and a distance may be formed between the first and second circumferences. A rim may be coupled at or adjacent to the first circumference of the conical structure. An ultrasonic transducer may be coupled to the second circumference of the conical structure.
