PROBLEM TO BE SOLVED: To provide a device capable of permanently transmitting sound such as operational sound / language sound of non-audible sound zone emitted from a device or an animal to a device manager, an operator, an animal ecology researcher or a zoo visitor for facilitating device management or animal research, or conversation sound and ambient sound to a hearing severely-impaired person to whom a hearing aid is invalid without affecting ruotine life/movement, along with maintaining the nature and the sound source location information of the sound. SOLUTION: The device bodies are attached to an external auditory meatus of both ears. Sound information inputted from a sound collection microphone provided at an external side of the device is processed for frequency analysis at an internal circuit, and drives a vibrator installed around an internal side of an external auditory meatus of the device in a spiral fashion corresponding to each frequency component. Because of attachment to the highly sensitive external auditory meatus, an amplifier circuit is simplified to bring a device of a smaller size. Since a hole (sound path) penetrates from the external side to the inside at the device, normal sound information can reach an eardrum even after attachment. COPYRIGHT: (C)2004,JPO
