Abstract

A sound reproducing apparatus is disclosed. The sound reproducing apparatus includes a signal processing unit, a first transducer, and a second transducer. The signal processing unit is configured to receive a sound signal and divide the sound signal into a first frequency component and a second frequency component. The first frequency component is at least partially different from the second frequency component, and the signal processing unit includes a delay unit configured to delay the second frequency band component. The first transducer is configured to convert the first frequency component from the signal processing unit into airborne sound. The second transducer is configured to convert the second frequency component from the delay unit into bone conduction sound.
