Background technique

In the prior art, the various insert earphones with multiple loudspeakers are had existed in the market, i.e., in small-sized ear Multiple audio drivers are installed in machine, have arranged in parallel, are also had in tandem.PlayGear Stealth is the ear of special designing Machine, small-sized earmuff require special closure/independent from sound source to audio space and resonant space, to voice output unit, Until entering the acoustic environment of hearer's ear canal, and more more direct more closed better.For PlayGear Stealth, there are three types of want substantially It asks: the comfort level that small size, the true stereo sound effect of low/medium/treble audio and hearer's wearing/hearer's ear are listened to.These It is required that must be realized in very small, closed, independent acoustic space and outer put in environment and structure, in particular how The structure and loadspeaker structure of front and rear part in so small earmuff cooperate together how to reach front and back sound wave can communicate with Resonance and generate the three-dimension stereo with Z axis depth.

The pleasant earphone of some twin loudspeakers in tandem is by the way of vent passage or sound channel rear end loudspeaking on the market The output of device sound guidance sound equipment port.For example, the Chinese patent 201180002097.4 of Matsushita Electric Industries is exactly in front and back end loudspeaking A vent passage is arranged between the first frame and the second frame of device, and the sound of second unit loudspeaker is led to first unit Sound equipment port is oriented to after sound mix.But such design, there are three problem, first problem is vent passage only to first unit It ventilates with sound wave before second unit, structure is all closing behind first unit and the second unit loudspeaker back side , the rear sound wave that no vent passage communicates；Second Problem is that vent passage detours from second unit side and is transferred to front end Apart from too long too narrow, weaken the sound wave dynamics of second unit；After third problem is first unit and second unit loudspeaker End directly emits to the space outside earmuff rear using closing " repulsion " and " offsetting each other " or the sound at rear, all There is no any rear end audio and resonance structure and function；Therefore, it is vertical that the three-dimensional with better Z axis depth also can not just be generated Body sound.

The patent China 200910127446.X of AKG Acoustics AG is to change using first transducer setting second Sound can be transmitted in the sound channel of device, and sealing forms sound channel before second transducer.Such design has a problem, just It is that front chamber is sealed, the sound channel for transmitting sound is sealed in the earplug area of front end, the subsequent space of second transducer and front chamber It is not communicated with, also with regard to without any sound wave resonance can be carried out for transmission to rear end spaces below, can not generate with Z axis depth The three-dimension stereo of degree.

Being preferably provided with for size of front loudspeakers 1018A and rear end loudspeaker 1018B are: front end be arranged one it is small-sized Simultaneously one large-scale audio drivers are arranged in rear end in audio drivers, or in the identical sound of front-end and back-end setting size Sound driver, or be that one large-scale audio drivers are set in front end and one small-sized sound driver is set in rear end, Etc., it depends on the circumstances.

To be applied in earphone embodiment different shown in Fig. 1 to Fig. 5 A, by front and back end loudspeaker 1018A/1018B And its double drive that front and back diaphragm element 1052A/B/BB and voice coil unit 1054A/B and sound hole unit 1058A/B is constituted Arrangement mode, design, function, shape, form, size, structure, position, type and the material of front/rear array element can roots According to needing to change.

Fig. 1 to 1E demonstrates a variety of outer/inner structures and system of In-Ear Headphones 1000 in detail.

As shown in each enlarged drawing of Fig. 1-1E earphone 1000, miniature loudspeaker 1018A and larger type speakers 1018B match It closes work and forms array element before and after double drive.The front end sound wave 1018AW and rear end sound wave of front loudspeakers 1018A transmission 1018ABW can be treble audio.The front end sound wave 1018BW and rear end sound wave 1018BBW of rear end loudspeaker 1018B transmission Or it can be bass and middle pitch audio.Front and back sound wave 1018AW/1018BW and 1018ABW/1018BBW pass through rear end vibrating diaphragm list First 1052B/1052BB and circular voice coil unit 1054B and back-end central sound hole unit 1058B generates and is transferred to rear end sound Sound resonator resonance and output together constitute the three-dimensional stereo effect in tri- axis of X-Y-Z, and in other words, one includes The three-dimensional (X-Y-Z) of low/medium/treble audio is stereo.Sound wave line 1018AW/1018ABW and 1018BW/1018BBW can be waited Away from be arranged in parallel, can intersect, or can also be arranged to be in different angles according to the arrangement position of front-end and back-end loudspeaker Degree.

There are spacing 1084 between the external structure of loudspeaker 1018A and 1018B.Front loudspeakers sound wave 1018AW/ There are sound depth 1086 between 1018ABW and rear end loudspeaker sound wave 1018BW/1018BBW.Sound depth or front and back sound wave It is the key factor of the three-dimensional stereo effect with Z axis effect true to nature apart from depth 1086.Sound depth or front and back sound wave It is directly related to spacing 1084 apart from depth 1086 and with front and back end audio unit 1032/1032B and front and back end Acoustic resonance Unit 1036/1036A/1036B cooperation obtains the sound of the depth in Z axis third dimension.It is also understood that sound is deep When degree or front and back sound wave occur more sound waves arrival sound delivery outlets because of distance difference apart from depth 1086 and spacing 1084 Between it is poor, thus produce front and back sound wave.

The position setting of loudspeaker 1018A and 1018B are extremely important, are in front-end and back-end at preceding than convenient setting Array is respectively set along a shared axis afterwards, such as identical central axis 1088, this central axis 1088 scheming The trunnion axis of earmuff 1006 is also represented in 1 embodiment.Axis 1088 is the central point of multiple loudspeaker 1018A and 1018B The central axis of the sound wave 1018AW/1018ABW and 1018BW/1018BBW of line and front and back loudspeaker 1018A and 1018B, It is also that the rear end diaphragm element 1052B/1052BB and circular voice coil unit 1054B of rear end loudspeaker 1018B and back-end central lead to Acoustic aperture unit 1058B is generated and the central axis of transmission sound wave resonance.Loudspeaker 1018A and 1018B are equal for these front-end and back-end It arranges and is in 90 degree of right angles with axis 1088 in front and back.

Loudspeaker be arranged along identical axis 1088 so that sound wave 1018AW/1018ABW and 1018BW/1018BBW and Depth 1086 is reinforced obtaining uniform and average three-dimensional stereo effect on identical waveform, wave rate and the pitch of waves.Similarly, Array arrangement is but also sound focus and sound wave 1018AW/1018ABW before and after this loudspeaker for having identical central axis 1088 With the central area for being distributed in three-dimension stereo space of the sound wave line of 1018BW/1018BBW equably fifty-fifty.

More importantly, sonic depth 1086 determines the double drive array element 1018A/ to arrange before and after Z axis The three-dimension stereo Depth Expansion of 1018B, obtains the sound effect on X-Y-Z axis.If depth 1086 is excessive, in Z The three-dimension stereo Depth Expansion of the double drive array element 1018A/1018B of the front and back arrangement of axis will overreact.If Depth 1086 is too small, then can weaken the three-dimension stereo of the double drive array element 1018A/1018B to arrange before and after Z axis Depth Expansion.Therefore need largely tested, for different types of loudspeaker determination on accurate location apart from depth 1086, this sound effect or extension not just to Z axis also facilitates sound effect or the extension of X-Y axis simultaneously.

Firstly, the numerical value of depth 1086 needs accurate setting to reach in all three dimensions of Y and Z axis along X Better sound effect.

Secondly, simultaneously, front and back the sound wave 1018AW/1018ABW and 1018BW/1018BBW of current rear speaker are in front and back In acoustic resonator 1036/1036A/1036B when cooperating, depth 1086 can be affected.Front and back acoustic resonator 1036/ 1036A/1036B obtains the acoustic echo/and sound effective value that certain is determined by outer shape and internal interference fit.Due to sound Wave, echo, the natural quality to reecho with sound gravitational field, the front and back end audio unit of different sizes, shape and structure 1032/1032B and acoustic resonator 1036/1036A/1036B will form different three-dimension stereos and echo and and sound effective value. If for the work of loudspeaker sound wave 1018AW/1018ABW and 1018BW/1018BBW, acoustic resonator 1036/ 1036A/1036B tension is too small, and depth 1086 can distort.If for loudspeaker sound wave 1018AW/1018ABW and For the work of 1018BW/1018BBW, acoustic resonator 1036/1036B excessively pine or it is excessive, then depth 1086 can be weakened or Effect is bad.

Again, as loudspeaker sound wave 1018AW/1018ABW and 1018BW/1018BBW and front and back audio unit 1032/ When the common cooperating of 1032B, depth 1086 can be affected.Audio unit 1032/1032B is by outer shape and interior shape Cooperation obtains certain sound effect, and usually one manufactures the sound functional component or wall inside the shell or one of sound effect, It can be contiguous location, be also possible to different units.If audio unit 1032/1032B is for loudspeaker sound wave 1018AW/ Too straight or roll up very much for the work of 1018ABW and 1018BW/1018BBW, depth 1086 may be twisted or weaken or effect It is bad.

There is a very small, limited and closed sound working space in speaker enclosure 1006.Therefore it is very limited herein Sound working space in, loudspeaker 1018A and 1018B generate respective sound wave 1018AW/1018ABW and 1018BW/ Identical axis 1088 in 1018BBW, front and back array, depth 1086, spacing 1084, front and back end audio unit 1032/1032B, Front and back end acoustic resonator 1036/1036A/1036B and voice output unit 1020 are all critically important, and it is real that they match merging jointly When generate three-dimension stereo in X-Y-Z dimension.

Since sound wave is three-dimensional, and there is directive property or guiding performance, when front end sound wave 1018AW and 1018BW are fluctuated When to the front end 1006A being connected with voice output unit 1020 very close to front end area 1032/1036 and earmuff 1006, after End sound wave 1018ABW and 1018BBW, which are fluctuated to very close to earphone enclosure 1006, has acoustic resonator 1036B in rear end with after Hold the rear end 1006B of audio unit 1032B.Because loudspeaker is mainly used to onwards transmission sound, front end sound wave 1018AW and 1018BW can be from front end audio unit 1032 and front end acoustic resonator unit 1036/ with sound wave directive property design structure It is acted on 1036A and rebounds, by the rear end diaphragm element 1052B/1052BB and annular sound of rear end loudspeaker 1018B Coil unit 1054B and back-end central sound hole unit 1058B (as structure or system) generation is communicated and transmitted and resonance, from And it is formed and returns to rear end sound wave 1018ABW and 1018BBW into the rear end audio unit with sound wave directive property design structure 1032B and rear end acoustic resonator 1036B is carried out communicating transmission and resonance and be exported.However, loudspeaker is to be designed to forward Sound is transmitted backward, therefore in the rear end audio unit 1032B and rear end acoustic resonator 1036B of earmuff rear end 1006B Extreme direction transmits sound wave directly from front end voice output unit 1020 forward by rear end sound wave 1018ABW and 1018BBW after resonance Occur.The front-end and back-end of earmuff 1006 are arranged in balance the air pressure of rear and front end sound wave in hole 1006C.Loudspeaker is even wanted Sound, such as 360 degree of transmission are transmitted to each direction, while also there is directive property or guiding performance.Rear end sound wave 1018ABW and 1018BBW is generated and by rear end diaphragm element 1052B/1052BB and circular voice coil unit 1054B and back-end central sound hole Unit 1058B is fluctuated to earmuff rear end 1006B, by same with rear end acoustic resonator 1036B and rear end audio unit 1032B When the synchronous matching Z axis depth effect that forms rear end Acoustic resonance and onwards transmission to generating X-Y-Z three-dimension stereo.Afterwards End acoustic resonator 1036B can be acoustic echo region or a rear end Acoustic resonance list in a rear end 1006B Member also includes the intracavity space region of rear button unit 1016.After one or more rear hole 1006C release on earphone enclosure It holds the air pressure of sound wave 1018ABW and 1018BBW to echo preferably to balance front and back end to export to obtain 3 D stereo sound effect with sound Fruit.Rear end audio unit 1032B includes the rear button of the audio unit 1032B inner and outer wall and rear end in the 1006B of rear end The inner and outer wall of component 1016.

In the example of Fig. 1 to Fig. 1 E, the entrant sound structure of the diaphragm element 1052B/1052BB of rear end loudspeaker 1018B With function and back-end central sound hole unit 1058B cooperation carry out front and back end sound wave 1018AW/1018BW and 1018ABW and 1018BBW's communicating and transmitting, from the rearmost end onwards transmission in backend unit 1006B, so that realizing has depth The three-dimensional stereo effect of Z axis depth.Because of rear end sound wave 1018ABW/1018BBW and front end sound wave 1018AW/1018BW tool There is the Z axis depth sound effect of the optimization of sonic depth distance 1084/1086, to realize better deeper X-Y-Z's Three dimensions and space it is stereo.

The diaphragm element 1052B/1052BB of the rear end loudspeaker 1018B of earphone 1000 have the function of entrant sound resonance structure and And effect.The diaphragm of loudspeaker is to generate sound in loudspeaker and transmit the main component of sound.Vibration of membrane of shaking generates sound wave It makes a sound.While vibrating diaphragm generates sound wave, it may have transaudient structure and function and effect.The vibrating diaphragm of ancient musical instrument is It is manufactured with natural material to generate and transmit sound, for example, the vibrating diaphragm of flute uses reed film or bamboo film, bulging vibrating diaphragm is using dynamic Object skin, the vibrating diaphragm of urheen is using boa skin, etc..The two-sided eardrum of two-sided drum taps sounding, and sound wave generates and be transferred to drum barrel chamber In resonance optimization amplification, then again by two-sided eardrum be transferred to outside form drum sound.The qin film sounding sound wave of urheen is generated and is passed It is defeated to amplify to resonance optimization in barrel, outside is then transferred to by qin film again and forms urheen sound.The bamboo membrane sounding sound wave of flute produces Resonance optimization amplification in flute pipe is given birth to and be transferred to, outside is then transferred to by bamboo membrane again and forms whistling.

That is, the vibrating diaphragm of bulging and urheen and flute is while generation sound wave makes a sound, these sonic transmissions are arrived In drum chamber, in the barrel (chamber) of urheen, in the sound pipe of flute, carry out after resonance again by the entrant sound structure and function of vibrating diaphragm to Outer transmission forms drum sound, urheen sound of musical instrument and whistling.Eardrum has the internal structure and function for being suitble to drum sound sound wave to generate and transmit It can and act on.Erhu music instrument film has the function of the internal structure and and effect that the several waves of suitable Erhu music instrument are generated and transmitted.Bamboo membrane tool There are the internal structure and function and effect of suitable whistling sound wave generation and transmission.

The vibrating diaphragm that earphone uses all is made material.The quality requirement of the artificial vibrating diaphragm of In-Ear Headphones is very high. The quality requirement of artificial vibrating diaphragm be concentrated mainly on the velocity of sound greatly and density it is low come the sensitivity that generates sound, the higher the better, audio is loud The broader stress the better, and sound quality transmittance is the bigger the better.The vibrating diaphragm of artificial material realize that the velocity of sound is big really and density it is low this two A element to sonic transmissions attribute.In acoustics industry, the vibrating diaphragm of artificial material is answered in electronic microphone and electrical loudspeaker With the most extensive and similar.The vibrating diaphragm of electrical loudspeaker and electronic microphone generally uses plastic polyester film or metallic membrane Or it is coated with the plastic foil of metal, alloy aluminum diaphragm or other metallic membranes can also be used.

Sound wave has radiation and reflection and transmission phenomenon is also an important feature of acoustic propagation.Since artificial vibrating diaphragm has Good transmitted acoustic pulse and transmissivity, when sound wave encounters artificial vibrating diaphragm face, almost all of acoustic wave energy can be transmitted to vibration Another side of film surface.The property of this acoustic wave energy radiation and reflection and transmission is determined by acoustic properties.

Therefore, the diaphragm element 1052B/1052BB of rear end loudspeaker 1018B can be very thin, generally less than 0.01 Millimeter is between 0.3 millimeter, it might even be possible to reach micron (μm).Its artificial material is conducive to the great velocity of sound, density also with Thinned suitable evacuation and be conducive to the generation and transmission of sound wave, thus increase that it is actively sensitive to the response power of sound wave, thus shape The characteristic impedance of sound wave itself is in close proximity to the characteristic impedance of acoustic wave transmission at it.So rear end loudspeaker 1018B There is diaphragm element 1052B/1052BB vibrating diaphragm similar or whole close to sound wave to transmit.In other words, rear end loudspeaker The diaphragm element 1052B/1052BB of 1018B is almost transparent for sound wave --- entrant sound, become transparent --- entrant sound Vibrating diaphragm, while the sound wave wave crest of diaphragm element 1052B/1052BB resonance or resonance is also broadened, especially by diaphragm element Audio unit and the multilayer audio unit of the audio structure 1052BB of resonance space that multilayer is just formed between 1052B are similar more Chamber (honeycomb effect) 1052BW1/2 is synchronous while more sound wave multilayers are transmitted resonant transmission with audio more to be strengthened and optimizes, Meanwhile more sound waves do not interfere with each other again.

For example, the thickness of the diaphragm element 1052B/1052BB of the nickel material of rear end loudspeaker 1018B is at 10-5 meters (0.01 Millimeter), and the wavelength for the common sound wave (20Hz to 20kHz) that human ear can be heard be two adjacent wave crests or two troughs it Between distance, generally between 17 millimeters to 7 meters, it is seen then that wavelength is far longer than vibrating diaphragm thickness, and vibrating diaphragm has very strong sound wave Transmittance.In this way, diaphragm element 1052B/1052BB of rear end loudspeaker 1018B itself also has in sonic transmissions simultaneously Between effect layer.When the composite construction on this diaphragm element 1052B/1052BB material middle layer thickness than the sound wave in layer Wavelength compares very little, then this middle layer acoustically just looks like there is no equally, sound wave still can be penetrated all, be reached Entrant sound functional harmony wave optimization function of the vibrating diaphragm to sonic transmissions.It is more especially by just being formed between composite diaphragm 1052B The audio unit multi-cavity (honeycomb effect) similar with the multilayer audio unit of audio structure 1052BB of resonance space of layer 1052BW1/2 is synchronous with audio more sound wave multilayers transmission resonant transmission while more strengthening and optimizing, meanwhile, more sound waves It does not interfere with each other again.

Meanwhile also used in the structure of the diaphragm element 1052B/1052BB of rear end loudspeaker 1018B and painting coat or Coating is in favor of acoustic wave transmission.The Film Coating Antireflection principle of this antireflection and optical device be it is the same, claim in acoustics teaching material For matching layer technology.For example, rear end moving-coil speaker 1018B MULTILAYER COMPOSITE diaphragm element 1052B/1052BB (on material and It is compound on painting/plating material) use the membrane type structure of plastic film or fiber membrane or any artificial material film can be with nickel plating Or it aluminizes or nickel plating or other coats of metal or any liquid crystal polymer are improved to the better sensitivity of sound wave and transmission And responding ability, reach its characteristic impedance that sound wave itself is in close proximity to the characteristic impedance of acoustic wave transmission, so, rear end The diaphragm element 1052B/1052BB of loudspeaker 1018B has whole transmissions and optimization similar or close to sound wave.Especially By the multilayer sound for just forming the audio unit of multilayer and the audio structure 1052BB of resonance space between composite diaphragm 1052B Imitate unit similar to multi-cavity (honeycomb effect) 1052BW1/2 more sound wave multilayers transmission resonant transmission it is synchronous with audio simultaneously more Reinforcementization and optimization, meanwhile, more sound waves do not interfere with each other again.

Rear end loudspeaker 1018B uses direct-injection type moving-coil speaker structure --- diaphragm of loudspeaker unit 1052B/1052BB With circular voice coil unit 1054B completely openly directly contact sound wave and, rear end diaphragm of loudspeaker unit 1052B/ It is directly communicated with back-end central sound hole unit 1058B and rear end cavity 1006B behind 1052BB.In this way, front and back end sound wave 1018AW/1018BW and 1018ABW/1018BBW just passes through (transmission) rear end diaphragm of loudspeaker unit 1052B/1052BB and ring Shape voice coil unit 1054B and back-end central sound hole 1058B and communicate cooperation synchronous flowing export simultaneously.Therefore, rear end loudspeaking The connectivity structure of device diaphragm element 1052B/1052BB and circular voice coil unit 1054B and back-end central sound hole unit 1058B (i.e. multilayer vibrating diaphragm composite construction) is achieved that rear end diaphragm of loudspeaker unit 1052B/1052BB is used as front and back sound wave The optimization function and resonance effect of 1018AW/1018BW and 1018ABW/1018BBW circulation, so that generating has better Z axis The three-dimension stereo of depth.

Front loudspeakers 1018A can use loudspeaker and its configuration as the loudspeaker 1018B of rear end, be also possible to Different structure or size or material or unit or technology and its configuration.That is, front and back end loudspeaker 1018A and 1018B can be the same, be also possible to different, being also possible to front loudspeakers unit 1018A may include multiple raise Sound device, being also possible to rear end loudspeaker unit 1018B may include multiple loudspeakers.In general, front loudspeaker 1018A volume It is small, generally in the moving-coil loudspeaker or 2-3 of 5-10 mm dia millimeter rectangular dynamic iron loudspeaker, subsequent loudspeaker 1018B Volume more greatly, generally in the moving-coil loudspeaker of 10-16 mm dia.It is of course also possible to front loudspeaker 1018A volume is big, behind Loudspeaker 1018B is more small in size or the volume of front and back loudspeaker 1018A/1018B all.

Front loudspeaker 1018A can be moving-coil vibrating diaphragm loudspeaker, be also possible to the loudspeaker of dynamic iron loudspeaker or other forms ?.Back speakers 1018B is also possible to moving-coil vibrating diaphragm loudspeaker, is also possible to the loudspeaker of dynamic iron loudspeaker or other forms.

The vibrating diaphragm 1052A/1052B/1052BB of front and back loudspeaker 1018A/1018B, can be the same, be also possible to not The same, respective design, material, size, specification, technique, structure, type, shape, system, mode, etc. is ok Be it is diversified, can also mutually using and be replaced mutually.

The design of front and back end center sound hole unit 1058A/1058B, material, technique, structure, size, specification, type, Shape, system, mode, etc. can be it is diversified, can also mutually using and be replaced mutually.Further, front and back The position of end center sound hole unit 1058A/1058B can cooperate front and back vibrating diaphragm 1052A/1052B/1052BB to transmit sound wave Needs and it is arbitrarily devised anywhere and angle.

The magnet unit 1056B of rear end loudspeaker 1018B includes the north and south magnetic pole of magnet arrangement, is passed through in current signal When, electric current and magnetic fluctuation are generated, causes the vibration of circular voice coil unit 1054B, to drive composite diaphragm 1052B/BB Vibration generates sound wave 1018B and makes a sound.Yoke unit 1060B is connection and the film edge for fixing diaphragm element 1052B/BB To make diaphragm element 1052B/BB tight and obtain abundant and free vibration together with voice coil 1054B.Magnet unit 1056B It can be what joint was integrated with yoke unit 1060B, be also possible to separate connection.

The magnet unit 1056A of front loudspeakers includes the north and south magnetic pole of magnet arrangement, when current signal passes through, is produced Raw electric current and magnetic fluctuation, cause the vibration of circular voice coil unit 1054A, so that diaphragm element 1052A vibration be driven to generate Sound wave 1018A makes a sound.Yoke unit 1060A is connection and fixes the edge of diaphragm element 1052A to allow diaphragm element 1052A is tight and obtains abundant and free vibration together with voice coil 1054A.Magnet unit 1056A and yoke unit 1060A It can be what joint was integrated, be also possible to separate connection.

Front and back end loudspeaker 1018A/1018B combines 1050 in tandem can have the combination of multiplicity variation, example Such as, the combination that can be two loudspeakers or more is also possible to loudspeaker one in front and one in back, and after two is previous, one after the first two, before two After two, it is more before mostly after, can also be equidirectional, different directions, angle arrangement, structure face to face, face face is staggered or angle Spend the combination of opposite, etc. multiplicity.

When being applied in all embodiments as shown in Fig. 1 to 5A, the position of all of above each unit and feature, Size, design, shape, function and material can depending on the circumstances or the needs of the situation change.

Figure 1B is to develop another example come on the basis of Fig. 1 to Figure 1A A.Before the loudspeaker 1018A/1018B of front and back end Permutation and combination 1050 is structure face to face afterwards.

The structure face to face that front and back end loudspeaker 1018A/1018B combines 1050 in tandem can also generate excellent well Elegant three-dimensional stereo effect.Structure makes between the loudspeaker 1018A/1018B of front and back multi-loudspeaker face to face in tandem Distance 1084 and its sound wave distance 1086 are definitely and clearly.In this way, the vibrating diaphragm of front and back loudspeaker 1018A/1018B 1052A/1052B/1052BB is also face to face.As the sound source of respective sound wave, diaphragm element 1052A and 1052B/ Depth distance 1084 between the distance between 1052BB namely front and back loudspeaker.The sounding sound of front end diaphragm element 1052A The distance of wave to voice output unit 1020BBB are front end sound wave distance 1086A；Rear end diaphragm element 1052B/1052BB's The distance of sounding sound wave to voice output unit 1020BBB are rear end sound wave distance 1086B.That is, depth distance 1084 Namely it is equal to the sonic depth distance 1086 that rear end sound wave distance 1086B subtracts front end sound wave distance 1086A.In this base On plinth, as the sound wave distance 1086 with Z axis depth with the distance in tandem 1084 of front and back loudspeaker is.Thus More convenient design in distance 1084 and sonic depth 1086 is planned, is arranged, structure, mode, position, etc., to generate Preferably with the three-dimension stereo and its effect of Z axis depth.

Due to being front and back end loudspeaker 1018A/1018B structure face to face, the vibration of front and back end loudspeaker 1018A/1018B Film 1052A/1052B/1052BB is also arrangement architecture face to face.Such permutation and combination will rearrange front and back loudspeaker The frequency of front and back the sound wave 1018AW/1018BW and 1018ABW/1018BBW of 1018A/1018B and fluctuation and resonance, to avoid Being directly overlapped or fighting or repelling between each sound wave, causes obscuring for sound wave output.

For example, being adopted between diaphragm element 1052A/1052B/1052BB before and after the loudspeaker 1018A/1018B of front and back end With the vibration mode for mutually avoiding and recommending.This mutual evacuation and the vibration mode recommended are related to entire front and back vibrating diaphragm list The whole design of first 1052A/1052B/1052BB and front and back magnet unit 1056A/1056B and front and back voice coil 1054A/1054B With the variation of material and structure, or even the variation of voice controller unit 1080 and its electronic audio signal may also relate to, For example, using different diaphragm elements or circular voice coil unit or ferromagnetic material and structure, in this way, front and back vibrating diaphragm 1052A/ It is formed complementary between the frequency of 1052B/1052BB and given in each other, to generate better three-dimension stereo.For another example using sound The frequency dividing management of sound controller 1080, high, normal, basic cent frequency arrive the separated place of front and back diaphragm element 1052A/1052B/1052BB It manages, formed complementary between the frequency to reach front and back diaphragm element 1052A/1052B and gives in each other, to generate better three-dimensional Stereo and its effect.

Fig. 1 C is to develop another example come on the basis of Fig. 1 to Figure 1B.Before the loudspeaker 1018A/1018B of front and back end Permutation and combination 1050 is 90 degree of right angles structure in tandem afterwards.Due to being 90 degree of right angles of front and back end loudspeaker 1018A/1018B Structure in tandem, the vibrating diaphragm 1052A/1052B/1052BB of front and back end loudspeaker 1018A/1018B are also 90 degree of right angles front and back Arrangement architecture.Front and back end loudspeaker 1018A/1018B combines 1050 right angle in tandem, and structure can also generate very in tandem Good outstanding three-dimension stereo and its effect.

At this point, the front and back sound wave that the vibrating diaphragm 1052A/1052B/1052BB of front and back end loudspeaker 1018A/1018B is generated 1018AW/1018BW and 1018ABW/1018BBW also forms a right-angle relationship.The sound wave center line of rear end loudspeaker 1018B The sound wave center line 1088SA of 1088SB and front loudspeakers 1018A is 90 degree of right angles, this just needs to rearrange front and back loudspeaking The frequency of front and back the sound wave 1018AW/1018BW and 1018ABW/1018BBW of device 1018A/1018B and fluctuation and resonance, to reach The three-dimensional stereo effect generated to optimal combination.One of benefit arranged in this way is exactly front end audio unit 1032 with before The space of end acoustic resonator unit 1036 increases and optimizes sound quality.

When the leading space of the diaphragm element 1052A of front loudspeakers 1018A increases, resulting front end sound wave 1018AW has more resonance spaces just to achieve the effect that fuller sound wave plays.If front loudspeakers 1018A is Based on high pitch, high pitch performance at this time will be more resonant and bold and unrestrained.Front end sound wave line 1088SA is directly up preceding It holds and plays and export in the increasing space of audio unit 1032 and front end acoustic resonator unit 1036.

Meanwhile responding space before the diaphragm element 1052B/1052BB of rear end loudspeaker 1018B and also accordingly increasing, Resulting rear end sound wave 1018BW and 1018ABW/1018BBW will be directly from rear end diaphragm element 1052B/1052BB It is output in more resonance spaces with back-end central sound hole unit 1058B to achieve the effect that more direct sound wave plays. Diaphragm element 1052B/1052BB is the combination of one or more layers composite diaphragm, and the edge of multilayer diaphragm element 1052B can be phase Even or separate.Circular voice coil unit 1054B and multilayer diaphragm element 1052B/1052BB are connected directly, and are segmented into multiple rings Shape voice coil unit structure corresponds to multilayer diaphragm structure and is respectively connected, or can be circular voice coil cellular construction corresponding one A diaphragm element structure or multiple diaphragm element structures, or it is also possible to a diaphragm element structure corresponding to one or more A circular voice coil cellular construction is just formed between MULTILAYER COMPOSITE diaphragm element 1052B and circular voice coil unit 1054B as a result, The audio structure 1052BB of multi-level or multizone audio unit and resonance space.The multilayer secondary noise of audio structure 1052BB Imitate unit similar to multi-cavity (honeycomb effect) sound wave multilayer transmission resonant transmission it is synchronous with resonance audio simultaneously strengthen and it is excellent Change.When circular voice coil unit 1054B feel in magnet unit 1056B electric signal flowing variation and generate vibration, thus band It moves the audio structure 1052BB synchronous vibration between diaphragm element 1052B and its composite diaphragm unit and generates sound wave 1018BW Make a sound the stereo of the dimension showed in sound wave X-Y axis.Audio between diaphragm element and its composite diaphragm unit Structure 1052B/1052BB has better sound wave resonance and effect of optimization to generate better sound wave and transmission.After if End loudspeaker 1018B is based on middle bass, and middle bass performance at this time will be deeper and strong.With Z axis depth The rear end sound wave line 1088SB of degree is directly forward in the increasing of front end audio unit 1032 and front end acoustic resonator unit 1036 It plays and exports in space, to generate the outstanding X-Y-Z three-dimensional stereo effect of the deeper Z axis depth of reinforcement.

Further, it is 90 degree of right angles structure in tandem that loudspeaker 1018A/1018B in front and back end combines 1050 in tandem It can also carry out various variation.The combination series in tandem 1050 of front and back end loudspeaker 1018A/1018B can be multiple angle Spend structural series in tandem.For example, the front and back diaphragm element 1052A/1052B/ of front and back end loudspeaker 1018A/1018B The angle combinations for the stereoscopic and omnibearing that angle 1062 between 1052BB can be from 0 degree to 360 degree, or be with 1088SA 360 degree of stereoscopic and omnibearing angle combinations of axis, or using 1088SB as 360 degree of stereoscopic and omnibearing angle combinations of axis.And And between two front and back axis 1088SA/1088SB or 360 degrees omnidirection angle combination.Multi-angle combines in this way Benefit it is very much, one of them is preferably the front and back diaphragm element 1052A/1052B/ of current back end loudspeaker 1018A/1018B When being in 25 degree of angles between 1052BB, produced by the diaphragm element 1052A/1052B/1052BB of front and back and the high pitch of transmission is resonant It echoes with bass and harmony can generate stronger sense of depth on Z axis.

In another example in the case where front and back diaphragm element 1052A/1052B/1052BB material and constant structure, using 0 Multi-angle to 45 degree of angles combines optimal resonance between the frequency to reach front and back diaphragm element 1052A/1052B/1052BB Cooperation, forms optimal front and back sound wave 1018AW/1018BW and 1018ABW/1018BBW, to generate better 3 D stereo Sound.

Fig. 1 D is the front and back end loudspeaker 1018A/1018B loudspeaking in combined system 1050 in tandem of Fig. 1 to Fig. 5 A The thin figure of another embodiment of device diaphragm element 1052B and rear end sound hole unit 1058B and its associated components.Rear end vibration Film unit 1052B/1052BB can also lead to sound using the back-end central of the vibrating diaphragm system cooperation perforation of bipolar system magnetic speaker Hole unit 1058B (channel of acoustic wave unit).

The soft magnetic materials round shape diaphragm used using the rear end diaphragm element 1052B/1052BB of bipolar system magnetic speaker, It is manufactured by cold-rolled low carbon steel band, Ⅴ-permandur alloy manufacture can also be used, thickness is at 0.2-0.22 millimeters.Very smooth vibrating diaphragm list First surface will carry out thickness of coating uniform treatment, and to reach smooth, magnetic property and elasticity well realize high sensitivity and frequency Responsiveness is good and stability is good.Circular voice coil unit 1054B is directly connected with magnet system 1056B using bipolar system, it should be noted that The accurate connection of north and south magnetism.Rear end diaphragm element 1052B/1052BB and bipolar system circular voice coil unit 1054B are combined into vibration Film driving unit 1052B/BB/1054B.In this way, producing one when sound electronic signal inputs circular voice coil unit 1054B A alternating magnetic field become with voice signal, this alternating magnetic field and the mutual superposition of original Constant charge soil or subtracts each other, and generates alternation and inhales Power attracts diaphragm element 1052B/1052BB to make torsional vibration, so that generating sound wave makes a sound 1018B.

The ultra-thin and coating of rear end diaphragm element 1052B/1052BB and have good acoustic wave transmission transporting, Er Qiehou The good complete plane of diaphragm element 1052B/1052BB is held openly directly to contact sound wave completely, while direct and ring again Shape voice coil unit 1054B and back-end central sound hole unit 1058B and rear end cavity communicate.In this way, front and back end sound wave 1018AW/1018BW and 1018ABW/1018BBW just passes through (transmission) rear end loudspeaker rear end diaphragm element 1052B/1052BB Coaxially flowing output is communicated with front and back Acoustic wave flow central axis 1088.Therefore, rear end loudspeaker rear end diaphragm element After the connectivity structure of 1052B/1052BB and circular voice coil unit 1054B and back-end central sound hole unit 1058B are achieved that Loudspeaker rear end diaphragm element 1052B/1052BB and circular voice coil unit 1054B is held to be used as front and back sound wave 1018AW/1018BW With 1018ABW/1018BBW circulation resonance optimization function and resonance effect, to generate better three-dimension stereo.

Therefore, in the example of Fig. 3 to Fig. 4 AA, the diaphragm element 1052B/1052BB's of rear end loudspeaker 1018B is saturating Acoustic form and function and back-end central through-hole unit 1058C/D cooperation carry out front and back end sound wave 1018AW/1018BW and 1018ABW's and 1018BBW communicating and transmitting, from the rearmost end onwards transmission in backend unit 1006B, so that realizing has The three-dimensional stereo effect of the Z axis depth of depth.Because of rear end sound wave 1018ABW/1018BBW and front end sound wave 1018AW/1018BW has the Z axis depth sound effect of the optimization of sonic depth distance 1084/1086, to realize more preferable Deeper X-Y-Z three dimensions and space stereophonic effect.

Fig. 5 and Fig. 5 A is to show another example.Front loudspeakers 1018A design shell unit 1006A before directly ining succession Voice output unit 1020 sound output channel 1020BBB in, before another front and back end loudspeaker 1018A/1018B Arrangement combination series 1050 include the rear end diaphragm element 1052B/1052BB of front and back end loudspeaker 1018A and 1018B with after afterwards End sound wave communicates unit 1058B and its associated components composite structure (i.e. multilayer vibrating diaphragm composite construction).The superiority designed in this way It is that earphone volume is smaller and whole finer.It is preceding since sound output channel 1020BBB enters the volumetric constraint in human ear road Hold loudspeaker 1018A just based on the loudspeaker of the moving-coil loudspeaker of small size or dynamic iron loudspeaker, rear end loudspeaker 1018B is still Based on moving-coil loudspeaker.

In this way, the sound space in entire earphone enclosure 1006 just covers the sound output channel of voice output unit 1020 In 1020BBB.The inner wall and bellmouth entrance Yan Bi of sound output channel 1020BBB, which is also designed and tied, constitutes front end sound unit 1032 a part.The internal cavity of sound output channel 1020BBB, which is also designed and tied, constitutes the one of front end acoustic resonator 1036 Part.In this way, the external structure of front loudspeakers 1018A includes and cooperates the front end audio unit 1032 in the 1006A of front end Resonator unit 1036/1036A, there are also the sound output channel 1020BBB in front end voice output unit 1020.In this way Design and structure superior point it is very much, first, since front speaker is advanced in sound output channel 1020BBB, whole product Pole reduces, and more meets the organization of human body and wearing comfort of human ear；Second, front speaker 1018A Forward, front end sound wave Ear-drum in 1018AW more adjunction human ear ear canal and acoustics is more directly and good；Third, 1032 He of front end audio unit The space of front end acoustic resonator 1036 also accordingly moves forward, and the resonance space of front and back sound wave, which increases, to be lengthened, between the loudspeaker of front and back Distance 1084 it is also corresponding lengthen, rear end diaphragm element 1052B/1052BB and back-end central sound hole unit 1058B are in front and back The space of end 1006A/1006B is more more conducive to the humorous of front and back sound wave 1018AW/1018BW and 1018ABW/1018BBW Vibration and directly transmission.That is, front and back sound wave axis 1088 is lengthened to after directly communicating from voice output unit 1020BBB Hold the rear end audio unit in diaphragm element 1052B/1052BB and back-end central sound hole unit 1058B to rear end housing 1006B 1032B and rear end acoustic resonator 1036B is up to rearmost end 1016, in this way, rear end sound wave 1018ABW/1018BBW resonance It is increased to maximum magnitude with transmission Z-direction range, Z axis longitudinal direction depth is lengthened to depth capacity, so that generating has more The well three-dimension stereo of the X-Y-Z of deeper depth effect.

Meanwhile the vibrating diaphragm of front loudspeakers 1018A is the diaphragm element 1052B/ with rear end loudspeaker 1018B upward 1052BB is oriented 90 degree of right angles, the direction line 1088AS of front end sound wave 1018AW be first upward, then with rear end sound wave Voice output unit 1020 of the 1018BW/1018ABW/1018BBW after sound output channel interior resonance together forwardly advances With the three-dimension stereo in the ear canal for being input to user, generating better Z axis depth.

Front loudspeakers 1018A can also be arranged using circle iron loudspeaker or dynamic iron loudspeaker or the loudspeaker of other forms towards front end Column, in this way, front loudspeakers 1018A is just and the direction of speaking of rear end loudspeaker 1018B is also possible to towards same direction Tandem is arranged with position or is arranged with the mutual multi-angle of position or dislocation.Front loudspeakers 1018A can also be using dynamic iron loudspeaker Towards rear end arrange, in this way, front loudspeakers 1018A just and rear end loudspeaker 1018B direction of speaking be face to face, It is also possible to tandem or is arranged with the mutual multi-angle of position or dislocation.

Meanwhile resonance and response space 1036 before the diaphragm element 1052B/1052BB of rear end loudspeaker 1018B It accordingly increases, resulting rear end sound wave 1018BW and 1018ABW/1018BBW will be directly from rear end diaphragm elements 1052B and back-end central sound hole unit 1058B is output in more resonance spaces 1036 and is broadcast with reaching more direct sound wave The effect put.If rear end, loudspeaker 1018B is based on middle bass, and middle bass performance at this time will be deeper With it is strong.Rear end sound wave line 1088 with more direct Z axis depth is directly forward in front end audio unit 1032 and front end sound It plays and exports in the increasing space of sound resonator element 1036, to generate the outstanding X-Y- of the deeper Z axis depth of reinforcement Z three-dimension stereo and its effect.

Further, it is 90 degree of right angles structure in tandem that loudspeaker 1018A/1018B in front and back end combines 1050 in tandem It can also carry out various variation.The combination series in tandem 1050 of front and back end loudspeaker 1018A/1018B can be multiple angle Spend structural series in tandem.For example, between the front and back diaphragm element 1052A/1052B of front and back end loudspeaker 1018A/1018B Angle can be combined with the multi-angle of stereoscopic and omnibearing.There are many benefit of multi-angle combination in this way, one of them is preferably current When being in an angle of 90 degrees between the front and back diaphragm element 1052A/1052B/1052BB of rear end loudspeaker 1018A/1018B, front and back vibration Produced by film unit 1052A/1052B and the high pitch of transmission is resonant and bass echoes and harmony can be generated on Z axis it is stronger Sense of depth.
