Abstract: A device, for transmitting or receiving ultrasonic signals, includes a transducer and an acoustic horn. The transducer is configured to convert between electrical energy and the ultrasonic signals, and may be a micro electromechanical system (MEMS) transducer. The acoustic horn is coupled to the transducer, and includes multiple apertures through which the ultrasonic signals are transmitted or received in order to manipulate at least one of a radiation pattern, frequency response or magnitude of the ultrasonic signals. The multiple apertures have different sizes.
