Abstract
The invention provides an earphone which comprises a guide pipe structure and is capable of generating a true three-dimensional sound effect. The earphone provided by the invention is a device which has the advantages that sounding units of a common headphone are connected through a unique double-sound chamber structure and two guide pipes which can bypass the head of a wearer, and the sound of a left sound channel and a right sound channel is properly delayed through the guide pipes and then is mixed with direct sound to be transmitted into human ears, so that the wearer can enjoy the sound effect which is similar to the sound effect of a listening room and has space sensation and sense of immediacy through a pair of earphones.
Description
Technical field
The present invention relates to a kind of earphone for sound system and communication system, particularly comprise the earphone of guide-tube structure.
Background technology
Occurred more and more eurypalynous earphone in existing market, especially those are for various Multifunctional MP 3 player, MP4 player and the product being similar to apple iPod player, mobile phone, panel computer etc.Earphone R&D and production personnel and the huge challenge faced by the producer are that increasing user requires more and more higher to the acoustics of earphone, not only need mate the high-fidelity full range music covering bass, middle pitch and high pitch, further, also want to reach three-dimension audio true to nature and effect.Present earphone on the market, substantially be all common dual-channel headphone, only only has the range of bidimensional (X-Y) strictly speaking, namely auris dextra can only hear the sound that right channel loudspeaker sends, left ear can only hear the sound that left channel loudspeaker sends, and can not hear that about picture is when music play by listening room audio amplifier, ear can hear spatial impression and the telepresenc of the sound that left and right acoustic channels audio amplifier sends simultaneously.It is the basic, normal, high sound audio sound of two dimension.And three kinds of audio frequency with basic, normal, high sound are only different volumes and content; " dual track " earphone can only be.In this case, so-called stereo be only three kinds of audio sound, and really is stereo, does not namely have three-dimensional acoustics.Due to the restriction of space and structure, these earphones do not have enough degree of depth of sound for the third dimension (Z) spatial impression and the width of range.Therefore, these earphones have no idea to obtain the spatial impression and effect with the X-Y-Z three-dimension stereo mating basic, normal, high sound audio frequency.
In the prior art, market has had the various earphone with multiple loud speaker, namely multiple audio drivers has been installed in earphone.The setting of these loud speakers and structure still still follow the set-up mode of traditional loud speaker: parallel transverse arrangement architecture.Reason loud speaker being arranged to parallel transverse arrangement architecture is that traditional sound equipment Study system needs all sound sources to be set at work be on the point of same parallel lines in a specific acoustic environment, particularly for those earphone containers containing multi-acoustical and multiple audio drivers.Even if having multiple audio drivers, basic, normal, high sound three kinds of audio frequency still can only produce different volumes and content, are generally in the acoustic space of this two dimension of X-Y.The good deep space echoed and effect can not be provided, so for multiple loud speakers of this parallel position relationship, appoint so exist cannot produce stereo really, the particularly problem of the spatial impression of sound.The sound of basic, normal, high sound audio frequency still can only be presented on the two-dimensional space of X-Y axle by these earphones comprising multi-loudspeaker, and the sound equipment degree of depth that cannot reach as listening room and effect is stereo.First be namely that Headphone structure is little, and sound is by the true stereo acoustic mass possessing three-dimensional (X-Y-Z) of high request.In the space that this is very limited, earphone needs better structure, better audio system, more reasonably arranges and obtain the relevant reverberant sound effect region of three dimensional sound of high-quality X-Y-Z dimension.Conventional bidimensional (X-Y) is stereo is not enough to the demand meeting people, is not also specifically real stereo.Parallel construction due to earphone does not have the spatial impression tonequality of the third dimension (Z axis), does not namely have space and the effect of the three-dimension stereo of X-Y-Z.
Typically, for existing earphone, we have no idea to ensure the tonequality of X-Y-Z three-dimension stereo audio and the spatial impression of three dimensional sound of earphone simultaneously.The stereo audio of the what is called that these earphones have does not have the spatial impression audio of the third dimension (Z), and or tune and structure do not adjust for the spatial impression of the third dimension (Z).
Therefore, generally, in order to solve the problem and defect, in order to make common headphones hear 3-D audio, player manufacturer generally adopts to be increased on a player if acoustics such as " cross feed sound, difference rings around, reverberation " is to meet the pursuit of auditor to earphone audio.And by the audio that this software imitates out, sound nature, can not be pursued the vast audition personage of high-fidelity tone color accept, do not accepted by professional person and " fan " especially.
Summary of the invention
For the earphone solving prior art cannot provide the shortcoming of the stereo audio of true three-dimension, the invention provides a kind of earphone of the produced vivid three dimensional audio containing guide-tube structure.Earphone of the present invention is by a common headphone phonation unit, by the double-tone cell structure of uniqueness, and be interconnected by two conduits that can bypass wearer's head, by conduit, the sound suitable time-delay of left and right acoustic channels is mixed the device that direct sound wave sends into people's ear again, make wearer can enjoy the acoustics with spatial impression and telepresenc as similar listening room by a set of headphones.
The object of this invention is to provide an earphone, have more 3-D audio true to nature than the existing earphone in market.And this audio is realized by two conduits; Left and right ear casing is interconnected by the conduit that two can bypass wearer's head, the sound obtained from left and right acoustic channels keynote room is led the secondary tone chamber of left and right ear casing by these two conduits by conduit, then from secondary tone chamber sound hole, the sound that loud speaker front, sound mix keynote room sends together is sent into people's ear; The distance of about 40cm is have passed from obtaining sound sound to the process by conduit sound being led secondary tone chamber after the loud speaker of keynote room at sound, the process that echoes of similar " diffuse reflection " of sound in sound chamber, keynote room and conduit in addition, the time delay of sound is had natural 1ms to 15ms, this is the music effect such as " difference ring around " " cross feed sound " " delay reverberation " just as installing additional in earphone player; The effect only produced by conduit is more naturally smooth, and auditor more can be allowed to accept.
Another aspect of the present invention is to provide a earphone, allows wearer have the selection of more multitone effect.This earphone can be installed one and can control the valve of connector size and inside secondary tone chamber, install the valve that a control panel sound hole goes out volume in keynote room and conduit connection, like this by regulating the size of each valve to recall different audios.
