Title ACOUSTIC CONVERSION DEVICE
Abstract The invention attempts to provide a new and unconventional acoustic space; the basic concept is to provide an acoustic space which realizes the movement of sound from inside the human body to outside of the human body, or reversely, from outside of the human body to inside of the human body. A sound output device mountable near the ear is used as the output means for internal sound positioned in the human head, and an externally located sound output device is used as the output means for external sound; the spatial effect of the sound is implemented as the acoustic space between inside and outside of the body. The acoustic conversion device is provided with a sound signal generation device (12), at least one internal sound output device (16) mountable near the ear of a listener, and at least one external sound output device (14) positioned at a distance from the listener. The internal sound output devices and the external sound output devices are capable of simultaneous output, and said devices output different sound information such that the listener can listen to sound from the internal sound output device (16) and the external sound output device (14).
