Abstract
The utility model relates to an earphone for positioning stereo. Auricles in the earphone form a concave shape, and are in a hemispherical shape or a semi-elliptic shape. The earphone is respectively arranged on the upper, the lower, the right, the left and the middle positions in the auricles. The utility model can automatically determine the three-dimensional direction of a sound source through the principles of binaural time difference, binaural sound intensity difference, and the filtering function of human ears in an auditory process. Thereby, people in an audio-visual environment have the feeling of self participation, and the capacity of the connection of people and machines is increased.
Description
The utility model relates to a kind of earphone to the three dimensional sound location.
In practical application at present, two types of earphones are arranged, be a kind of be big auricle earphone, another kind is a microtia ear plug machine, although they possess stereo binary channels, because the sound of can only playback having recorded can not be determined direction to three dimensional sound, therefore, can not be used for the application system that requirement has high fidelity and feeling of immersion.
The purpose of this utility model proposes a kind of obscuring of virtual sound source orientation judgement that reduce, and increases the direct stimulation of sound signal to external ear, determines the direction of three-dimensional sound source, thereby realizes a kind of three dimensional sound location earphone of the fidelity of enhancing audio visual environment.
Approximate hemisphere of the utility model appearance profile or semielliptical shape, but its diameter is bigger than the wheel of common big auricle earphone greater than the maximum gauge of the outer auricle of people, left and right sides Headphone structure symmetry, the middle company of using steel band connects.Auricle inwall at hemisphere or semielliptical shape earphone is installed a plurality of micro earpieces, and it is provided with the position decides by Sounnd source direction, and the quantity of micro earpieces is then determined according to locating accuracy.Concrete structure of the present utility model is: auricle 1 is mould of plastics spare, be concavity, be hemisphere or semielliptical shape, a micro earpieces 2 is respectively adorned in branch upper and lower, left and right, middle part in auricle 1, be independent mutually between the micro earpieces 2, have one deck to approach sponge above the micro earpieces 2, micro earpieces 2 also can be arranged in order in auricle 1, until filling auricle 1.The utility model is left and right two, is symmetry.Middle by steel band 3 connections, 4 is the micro earpieces line.
Operation principle of the present utility model is ears time difference and the binaural sound strong difference by the people, and the filter action of external ear in sound localization, the position (with respect to people's ear) of the micro earpieces of sending sound signal and the direction (with respect to people's ear) of virtual sound source are consistent, thereby make sound signal start the external ear that corresponding micro earpieces directly stimulates the hearer by Sounnd source direction.
The utility model has strengthened the fidelity and the presence of audible environment or virtual environment, has promoted perception and understandability to the human auditory.
Fig. 1 is the utility model principle assumption diagram
Fig. 2 is the principle assumption diagram of micro earpieces in the utility model
Embodiment: the utility model outer profile size must be greater than people's outer auricle, and the size of micro earpieces is little, and its quantity is decided according to locating accuracy, but will install five at least.The structure and material of micro earpieces is identical with the structure and material of common little earphone.
Claims (3)
1. the earphone to the three dimensional sound location comprises auricle, steel band, it is characterized in that: also comprise micro earpieces 2, divide upper and lower, left and right, middle each position in auricle 1, each installs a micro earpieces 2, and is independent mutually between the micro earpieces 2.
2. earphone according to claim 1 is characterized in that: micro earpieces 2 also can be arranged in order a plurality of in auricle 1 by Sounnd source direction.
3. earphone according to claim 1 is characterized in that: auricle 1 is concavity, is hemisphere or semielliptical shape.
