Description

The multi-sound-channel earphone of a kind of pair of film, two conduction
Technical field
The present invention relates to a kind of earphone of novel structure, exactly, relate to the multi-sound-channel earphone of a kind of pair of film, two conduction, belong to the technical field of audio output apparatus.
Background technology
It is human that have two kinds of approach: a kind of is air transmitted when receiving the outside sound signal, i.e. acoustic vibration people's ear-drum, and the conduction by phonophore produces cochlea and stimulates, and conducts to brain via auditory nerve again and produces the sense of hearing.Another kind is an osteoacusis, and the sound wave of vibration is passed to phonophore by skull with signal earlier, and can produce cochlea equally stimulates, and conducts to brain via auditory nerve again and produces the sense of hearing.
At present, in order to reduce the maximum sound pressure of earphone dedicated speakers, associated production producer has adopted various hearing protections and earflap technology, for example, the manufacturer that makes audio player has adopted according to reproduction time length and the technology of volitional check volume perhaps adopts the technology etc. of being fade-in fade-out; Also there are some manufacturers to adopt the earphone that reduces the environmental noise technology, make the user when amount of bass, also can enjoy better tone quality.Other approach also has: active earphone is adopted the gain that reduces amplifying circuit, Passive earphone is adopted impedance that small resistor strengthens earphone of serial connection, or adopt the lower magnetic material of magnetic energy level or reduce the magnet volume, be used to electro-acoustic conversion efficiency that lowers by earphone or the like.
In order to realize multichannel sterego, conventional earphone is that 2~3 loud speakers are set in the housing of each earphone.Because the volume in the earphone case is limited, cause the installation site of these loud speakers very compact, thereby the sound channel position that makes loud speaker send separately is also approaching relatively.Like this, though a plurality of sound channel is independent sounding, for ear-drum, it is heard remains a kind of approximate mixing sound source so poor effect.
The defective of traditional bone conduction earphone is that range is broad inadequately, especially performs poor at HFS.
Therefore, how to improve the structure of earphone, enable to play well multichannel sterego, realize audio preferably, just become the focus that those skilled in the art pay close attention to.
Summary of the invention
In view of this; the multi-sound-channel earphone that the purpose of this invention is to provide a kind of pair of film, two conduction; be used to overcome the deficiencies in the prior art; this earphone is effectively being protected on the basis of user's hearing; both kept the stimulus intensity certain to the generation of cochlea; have the better tone quality effect again, be of value to hearer's physical and mental health.
In order to reach the foregoing invention purpose, the invention provides the multi-sound-channel earphone of a kind of pair of film, two conduction, each earphone wherein is provided with: metab and the cylindric yoke that is installed in metab central authorities and the outside thereof, be the assembly that coaxial radially tactic cylindrical shape permanent magnet, coil windings and cylindrical shape yoke constitute; Seamless binding has spherical shape sound film above the annular yoke; It is characterized in that: the opposite side of described metab connects another base by screw, and is provided with the Round Membranes sheet between these two bases, also is respectively equipped with spring shim between this Round Membranes sheet and two bases; The external diameter periphery of this Round Membranes sheet is fixed with the conduct vibrations cylinder in the outside close but that do not touch described assembly, and the other end of this conduct vibrations cylinder is the circular buffer gasket made from flexible material.
Described cylindric yoke and cylindrical shape yoke all are the high conducting magnetic components that constitutes with the silicon steel sheet stack of setting shape.
Metab material in the described assembly is the high permeability material of fe-Ni soft magnetic alloy class, and the material of another base is engineering plastics.
Described pair of film is spherical shape sound film and Round Membranes sheet, and wherein, spherical shape sound film adopts traditional sound membrane material to make, and the material of Round Membranes sheet is the magnetostrictive material that comprise Tb-Dy-Fe alloy.
Described two conduction is to conduct sound to auditory nerve respectively by air and skull to produce the sense of hearing; The electromagnetic force that produces when tone currents is flowed through this earphone coil windings has the part electromagnetic force directly to drive spherical shape sound film and sounds, by air transmitted to ear-drum; Another part electromagnetic force is transmitted to the Round Membranes sheet by metab, make vibrating diaphragm produce vibration and drive the conduct vibrations cylinder to vibrate with circular buffer gasket, thereby cause the skull vibration and conduction sound to auditory nerve.
The height of the cylindrical shape permanent magnet in the described assembly, coil windings and cylindrical shape yoke is identical or close; Described conduct vibrations cylinder adds that the height of circular buffer gasket is greater than the total height of the cylindrical shape yoke spherical shape sound film bonding with it.
Described multi-sound-channel earphone is provided with the one or more earphone that is provided with respectively in people's ear both sides.
As everyone knows, learn that human judgement to sound source position is based on the difference of sound wave to people's ear active position, and two ears receive time difference of sound wave about depending on from acoustic angle.The osteoacusis of sound also can satisfy the demand that people judge sound source position fully.The essence of loud speaker is a kind of transducing head that utilizes electromagnetic induction principle audio signal to be converted to the sound film vibration signal, the magnetic field that is produced when tone currents flows through the solenoid winding interacts with the magnetic field that magnet produced that is fixed on the coil yoke, drive the sound film that is fixed on the coil yoke thus and produce vibration, this is traditional sound conduction mode.On the other hand,, by this this vibration signal is passed to cochlea, is passed to brain and produces the sense of hearing via auditory nerve again if consequent sound film is vibrated directly contact people's skull.Via the acoustic vibration of air transmitted, can remedy range that sound exists and the deficiency aspect the tone color when osteoacusis, have better tone quality.And, both ensured by the sound of skull conduction and the power output of earphone can reduce acoustic pressure again, thus protection hearing.
The multi-sound-channel earphone of the two films of the present invention, two conduction compared with prior art, have the following advantages: the Round Membranes sheet of between the base of the base of metal magnetic conducting material and engineering plastics, installing by spring shim, so just the part electromagnetic force is acted on this Round Membranes sheet, its vibration passes to the user by the osteoacusis mode, thereby reduced the acoustic pressure of earphone, guaranteed the power of not loss earphone simultaneously.
Multi-sound-channel earphone of the present invention adopts the transfer voice mode of two films, two conduction; both can keep certain stimulus intensity; can effectively protect user's hearing again; wherein by airborne sound; replenished the deficiency of osteoacusis sound aspect range and tone color; also have the better tone quality effect, hearer's physical and mental health is benefited.And, multi-sound-channel earphone of the present invention can be installed the earphone of any amount on any part of skull, make people's auditory nerve can clearly distinguish the sound that transmits from any different parts of skull, and form a grand sound field jointly with actual position sense by each bone conduction earphone.Moreover multi-sound-channel earphone of the present invention simple in structure, practical has good application prospects.
