    Abstract: An integrated transducer device includes an optical transducer and an acoustic transducer integrally joined with the optical transducer. The acoustic transducer includes a membrane responsive to acoustic signals, the membrane being aligned with the optical transducer such that optical signals emitted or received by the optical transducer pass through the membrane. A propagation direction of the acoustic signals emitted or received by the acoustic transducer is collinear with a propagation direction of the optical signals emitted or received by the optical transducer.

    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 electro-mechanical 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.

    Abstract: A horn coupled to multiple acoustic transducers includes first and second throat portions and a mixing area integrally formed with the first and second throat portions. The first throat portion has a first throat opening adjacent to a first transducer, and the second throat portion has a second throat opening adjacent to a second transducer. The mixing area includes a common mouth opening shared by the first and second throat portions for at least one of transmitting or receiving acoustic signals. At least one dimension of the first throat portion is different from a corresponding dimension of the second throat portion, so that a first cutoff frequency corresponding to the first throat portion is different from a second cutoff frequency corresponding to the second throat portion.
