Description
Technical field:
Multi-sound-channel earphone relates to the multi-sound-channel earphone that is used to reproduce sound.
Background technology:
Earphone is a kind of small-sized sound-reducing device, it has, and volume is little, advantage such as be easy to carry, can make the people can be under the situation that does not influence other people, the music that indulges in luxuriousness to one's heart's desire and appreciation program, but conventional earphone generally is monophony or two-channel sterearphone, along with development of science and technology, the utilization of multitrack surround sound technology is increasingly extensive, conventional earphone can not satisfy the demands, multi-sound-channel earphone arises at the historic moment, the characteristics that multi-sound-channel earphone is long-pending less except that the body of inheriting tradition earphone, be easy to carry, be independent of each other with environment, also adopted the multichannel technology.
Summary of the invention
Play the sound of multichannel audio for realizing earphone, this multi-sound-channel earphone provides a solution, the technical scheme of this multi-sound-channel earphone is: this multi-sound-channel earphone can be divided into sound-reducing part and feedback part branch on functional structure, sound-reducing partly is responsible for the reduction of multi-channel sound, comprise a set of speakers and a rectangle solid space, loud speaker is placed in the rectangle solid space and according to the requirement of multichannel reduction and places, in order to the reduction multi-channel sound, the feedback part divides acceptance and the transmission of being responsible for sound, form by bionic ear and feedback sound channel, bionic ear is responsible for compiling of sound, the feedback sound channel is responsible for the sound that bionic ear is accepted is imported into duct, listen attentively to multi-channel sound in order to the simulation external ear in the space, thereby realize sound with earphone reduction multichannel.
Its principle is wanted to talk about from our organ ear that is subjected to earlier, as Fig. 2, we know that people's ear can perceives sound and can distinguish the direction of sound, but from related data, distinguish in the orientation for ear and to know on the mechanism also there not be definite conclusion now, the author is not that the expert of this respect more is not authority, but this problem also there was thinking, importantly the author will introduce thinking of the present invention, we know that external ear is responsible for collecting sound, inner ear is responsible for the identification perception of sound, but for mechanism wherein is not fully aware of, the author thinks deeply from bionic angle, think that the structure of ear is the reason place, examine structure in external ear, the author thinks that the many folds on the external ear are concavo-convex and is used for filtering noxious noise and collects from the sound of different directions, and a sound of collection back all directions is gone into duct by the arrangement rear feed, the author thinks that the process of sound of this collection is " modulation " process, being that many folds on external ear are concavo-convex as part sound curves transmission, phase place when it imports duct into is inevitable different with original sound with time delay, then through inner ear " demodulation ", the people just can perceives sound and is taken one's bearings, based on above my understanding, the solution of the present invention has been proposed.
Sound-reducing part: in the multichannel technology, a best point i.e. " emperor position " is arranged in people's the hearing pickup position, as in the room to each function audio amplifier put comparatively symmetry and well-behaved, as seen our ear is when appreciating multi-channel sound, the sound field that ear is accepted is put preferable with rectangle, so sound-reducing of the present invention partly adopts in the rectangle solid space loud speaker is installed, be used to simulate the solid space in the room, the placement of loud speaker is to place according to the replay request of multichannel, can truly restore the sound of multichannel.
Feedback part branch: form by bionic ear and feedback sound channel, bionic ear is copied according to people's ear structure quality, so external ear that can the anthropomorphic dummy is compiled the multi-channel sound of reduction, again by feedback sound channel feed-in duct, carry out perception by the inner ear organ, thereby realize listening attentively to multi-channel sound with earphone, the direct feed-in inner ear of sound that sends of conventional earphone loud speaker in addition, sound not having spatial impression and acoustic pressure not to obtain buffering, sound can cause damage to the hearing of ear when using for a long time.
Need explanation be, be the formulation summary of the invention, in full only to only to the important structure of one side earphone in addition explanation, real use should be about two cooperate ears to use, also should comprise accessory structures such as ear clip outside it, but not be emphasis of the present invention, do not discussed.
By above argumentation to this multi-sound-channel earphone, can be summarized as: the reducible multi-channel sound of acoustic playback part, the feedback part divides can simulate external ear multi-channel sound fidelity feed-in inner ear, so this multi-sound-channel earphone can realize reducing the function of multichannel audio, it is not enough and reduce the sense of hearing infringement of sound to people's ear to overcome existing earphone spatial impression effectively.
