Title: ACOUSTIC OUTPUT DEVICE AND CONTROL METHOD THEREOF
Abstract:
An acoustic output device and a control method thereof are provided. The acoustic output device includes: at least one first speaker configured to output a first sound range; a plurality of second speakers configured to output a second sound range that is different from the first sound range; a first crossover circuit connected to the first speaker and one of the plurality of second speakers; a second crossover circuit connected to the first speaker and another of the plurality of second speakers; and a processor configured to control the first and second crossover circuits to provide acoustic signals to the first speaker and the plurality of second speakers, wherein a frequency band of an acoustic signal provided to the first speaker connected to the first crossover circuit is at least partially different from a frequency band of an acoustic signal provided to the first speaker connected to the second of crossover circuit, and wherein a frequency band of an acoustic signal provided to the one of the plurality of second speakers connected to the second crossover circuit is at least partially different from a frequency band of an acoustic signal provided to the other of the plurality of second speakers connected to the second of crossover circuit.
