Description
Technical field
The utility model relates to a kind of acoustics, particularly a kind of acoustics of utilizing scalp to listen sound.
Background technology
At present, people come listening, music song, appreciation film and television sound with ear, also do not know to remove listening and music song and appreciation film and television sound with the skin of head nerve, also do not have such product now.Once the someone attempted to use the bone conduction theory, and the bone conduction product of mechanics of communication is realized music appreciating, listened the home theater film audio, but has all failed.Because the bone conduction theory can not solve the technical problem of sound field location on the sense of hearing, can't reach home theater solid space surrounding sound effect.The bone conduction oscillator is the device of communication speech usefulness, does not only have bass but also do not have high pitch, has only middle pitch, so that the music effect is short of very much is extremely imperfect.The someone attempts single raise earphone more again, and the result makes whole sound field more uneven on the contrary, can't realize three-dimensional surround sound sound field locating effect at all.
The physiological property of the neural audition of scalp is: the scalp neurokyme is heard the sound of 1Hz one 20000Hz frequency range, especially this utmost point bass frequency range of 1Hz～20Hz, the scalp nerve has been listened all, head and shoulders above people's ear audition scope, people's ear can only be listened 20Hz～20000Hz.
