摘要： 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.

摘要： A transducer device includes an acoustic transducer, a parameter extractor and a feedback circuit. The parameter extractor is configured to extract an operating parameter from the acoustic transducer. The feedback circuit is configured to generate a correction signal based on a difference between the extracted operating parameter and a corresponding reference parameter. The correction signal is applied to adjust the operating parameter of the acoustic transducer.
