A kind of skin listening device and listening method thereof

Abstract

The invention relates to a skin listening device and a listening method thereof. The skin hearing device includes a microphone, a first conversion unit for converting an audio electrical signal into an electrical pulse signal of the same frequency and amplitude, a pulse output terminal, a power supply, a switch and a vibration friction unit for driving the electrode vibration of the pulse output terminal, The pulse output terminal includes positive and negative electrodes. At least one electrode of the pulse output terminal is connected in series with the vibration friction unit. The power supply supplies power to the first conversion unit. The units are sequentially connected in series, and the electrodes at the pulse output end contact the skin surface with the large auricular nerve under the skin when in use; the invention is ingeniously designed, and converts the acoustic wave electric pulse signal into a neurobiological pulse signal by using the conductive effect of the skin, and converts the neurobiological pulse signal by using friction. The amplitude of the signal is amplified; the listening method is obviously different from the bone conduction vibration listening method and other skin conduction listening methods.

Description

technical field [0001] The invention relates to a sound listening device and a sound listening method, in particular to a skin listening device and a sound listening method. Background technique [0002] In the current medical field, lesions occur in the auditory nerves and central centers at all levels in the auditory system in the sound transmission, sensory sounds and auditory conduction pathways, causing hearing dysfunction and varying degrees of hearing loss, collectively referred to as deafness. [0003] According to the different parts of the lesion, it is mainly divided into three categories: conductive deafness, nerve deafness and mixed deafness. Deafness born in the sound-conducting part of the external auditory canal and middle ear is conductive deafness; deafness occurring in the sensory and nerve parts of the inner ear, auditory nerve, and auditory center is sensory deafness; there are abnormalities in both the conductive part and the sensory nerve part Deafnes...
