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.

Abstract: A method for testing user experience, comprising steps of: acquiring test indicating information; releasing a main task and an auxiliary task according to the test indicating information, each auxiliary task includes the main task and a corresponding physical signal providing prompting effect or inhibiting effect to the main task; acquiring feedback response information of a subject corresponding to the main task and the auxiliary task. In the technical solution of the present disclosure, through comparison of feedback response information of the subject between the auxiliary task and the main task, the perception situation of the subject on physical signals can be determined, and through comparison of feedback response information of the subject between the auxiliary tasks, the perception situation of the subject on different physical signals can be determined, thereby improving the effectiveness of the test result on perception attributes of physical signals.
