Description

A kind of osteoacusis hair band

Technical field

The present invention relates to a kind of osteoacusis hair bands, belong to Intelligent hardware wearable device technical field.

Background technique

In the prior art, people generally use the fixed hair of hair band, maintain hair style, in addition traditional hair band also has decoration Beautiful function.But this traditional hair band has a single function, do not have listen to music, making and receiving calls, the intelligence such as personal voice assistant The function of energyization.

In order to make hair band have the intelligentized function such as interactive voice, need to introduce sound conduction technology.In general, we listen To most of sound be by sound wave by air transmitted.The sound wave of air transmitted reaches cochlea, inner ear by external ear, middle ear And it is perceived by auditory nerve.In addition to this, sound wave can also be converted into the mechanical oscillation of different frequency, by the skull of people, Temporal bone, osseous labyrinth, inner ear lymph transmitting, spiral organ, auditory nerve, auditory center transmit sound wave, and here it is bone conduction technologies. Air transmitted sound wave, which refers to, to be transmitted by external ear, middle ear to inner ear；Osteoacusis is then vibration skull or temporal bone, does not pass through external ear It is transmitted directly in inner ear with middle ear.Relative to traditional air transmitted mode for generating sound wave by Loudspeaker diaphragm, bone is passed The step of eliminating the transmitting of many sound waves is led, can realize clearly sound-reducing in a noisy environment, and sound wave will not Other people are influenced because of spreading in air.The electro-acoustic element of bone conduction technology is divided into bone conduction vibrator and osteoacusis Mike Wind.Bone conduction vibrator is called to listen to sound for called.Air transmitted loudspeaker in the prior art is that electric signal is converted Auditory nerve is reached for sound wave.And bone conduction vibrator is then that the vibration signal of electric signal conversion is directly passed through bone and reached to listen mind Through.The difference of the two is that the transfer medium of sound wave (vibration signal) is different.Bone-conduction microphone technology send words to receive for sending words Collect sound.Conductance send words to be sound wave and reaches microphone by air, and bone-conduction microphone words are then directly vibrated by bone transmitting and believed Number.In contrast, bone conduction technology has the following advantages that：

1. ear is made freely to perceive the ambient sound of surrounding, therefore ears can be opened, improve the energy that user perceives environment Power and the safety used.

2. bone conduction device is unpleasant to the ear, eardrum is not injured, avoids impaired hearing, comfort and safety can be improved Property.

3. bone-conduction microphone collects user speech by vibration, the noise reduction of voice communication may be implemented, mask completely Ambient noise.

When using traditional air transmitted earphone, ambient noise would generally hinder user called and send words, because environment is made an uproar Sound and voice are mutually obscured during air transmitted, can all be conducted to auditory nerve.When user carries out complex environment activity When, for example, when running body-building, driving vehicle, since air transmitted earphone needs the pleasant or entire user ear canal of covering, user It is hardly perceivable the sound of ambient enviroment, such as：The automobile nearby crossed, other people call etc..This usually can to user with Carry out inconvenient or even security risk.In addition, pleasant air transmitted earphone, which is used for a long time, can damage the hearing of user, it is serious to lead Cause is become deaf.

But bone conduction technology in the prior art also have the shortcomings that it is following several：

1. the quality of bond-conduction sound is related with the contact position of bone.

2. bone and tissue can generate the amplitude fading with frequency selectivity and delay, high-fidelity to vibration signal Or the audio signal in broadband is difficult through bone conduction to auditory nerve.

3. called using bone conduction technology or send words, bone conduction device must be close to bone, and sound wave directly passes through bone Reach auditory nerve.Wearing mode determines that bone conduction device must conduct the compressing of bone conduction device height on bone, one Denier absent-mindedness just will affect the quality of audio transmitting.The wearing mode of this height compressing bone makes user's relaxing in use Suitable sense, skin health etc. are influenced to different extents.

4. the prior art is without really solving the problems, such as that osteoacusis leaks sound because of the characteristic of solid conduction vibration.This is Because the prior art is all to be compensated by big volume, big vibration signal and the skeleton of frequency dependence and tissue attenuation vibration Signal, but this method will lead to leakage that sound is serious, or need bigger power, bone conduction vibrator volume, weight are significantly Increase, causes equipment whole excessively heavy.

The hair band ontology 100 includes main body and two extending bodies 8, and two extending bodies are according to scheduled curvature point It is not connected to the both ends of main body, and two extending bodies allow to adjust its respective length.

Specifically, hair band ontology is made of flexible material, the poly- carbonic acid for generalling use nonhazardous, not causing skin allergy Ester (PC) material.Hair band ontology has a curvature, is attached to hair holding part.Hair band ontology includes main body, and two extending Body is connected respectively to the both ends of main body according to certain curvature, and two extensions be attached respectively to hair holding part and Allow to adjust its respectively length.The purpose of this design is the skull profile for adapting to different user, to be further ensured that bone Conduction oscillator and related sensor can contact skin area, rather than be covered with dense hair area.The coverage area of hair The performance and precision of osteoacusis and health sensor will be substantially reduced.It therefore, can be with by the extension of flexibly adjustment hair band Realization locks it in most suitable contact position and is used to guarantee functionality appropriate.

Circuit main board and rechargeable battery are successively fixed in hair band outer body, the two is distributed in the holding of hair band ontology two sides The balance of weight.Equably fixed bone conduction vibrator and bone-conduction microphone on the inside of hair band ontology；At least 2 osteoacusis Oscillator is located at hair band ontology both ends, is tightly attached to the temporal bone part on rear side of ear, because temporal bone is best osteoacusis position. Wherein, it is attached between bone conduction vibrator and hair band ontology by leakproof sound buffer.Hair band ontology needs and leakproof sound is slow Device close adhesion is rushed, for preventing bone conduction vibrator from hair band ontology is passed in vibration, its vibration is caused to generate leakage sound.Osteoacusis vibration It needs to wrap up by sponges cover on the direction of son contact skull, in this way during bone conduction vibrator and skin contact, sponges cover Can be located at not only comfortably directly can pass to skull for vibration between the two, but also can be by filtering out the high frequency audios of some oscillators Frequency part, so that the sound of osteoacusis sounds softer, it is not dry and astringent ear-piercing.At least 1 bone-conduction microphone needs position Middle position on the inside of skull apical position, that is, hair band ontology.Because skull top skin is relatively thin, can be very good to receive Collect the sound that skull transmitting comes.

Fig. 4 is a kind of typical structural schematic diagram of one point of Multi-audio-frequency power splitter of the invention.One point of Multi-audio-frequency power splitter For reducing circuit complexity and manufacturing cost.As shown in figure 4, one point of Multi-audio-frequency power splitter passes through to insertion terminal and circuit The port of bone conduction vibrator driver on mainboard is connected, and is divided into multichannel sound after the closed welding portion of heat-shrinkable T bush The positive negative signal of frequency wire rod output；The metal core of audio wire rod connects multiple bone conduction vibrators.Fig. 4 schematically shows connections The case where two bone conduction vibrator (bone conduction vibrator 1 and bone conduction vibrators 2 in Fig. 4), but those skilled in the art are entirely capable of It is enough to understand, it can connect more than two bone conduction vibrator here.

The present invention proposes noise cancellation technique to solve the problems, such as ambient noise interference.The present invention has several types Bone conduction audio-frequency element is arranged.Wherein bone conduction vibrator is arranged on the inside of hair band ontology and can touch the temporo of user Skin outside bone, and non-hair covers area part.Temporal bone can direct conduction vibration to the cochlea nerve of user, allow user to hear logical Cross the sound of conduct vibrations.The size of hair band ontology of the invention should rationally design, the hair for contacting with temporal bone external skin Hoop bulk material and shape design guarantee that sufficiently high oppressive force can be provided.At least two bone conduction vibrator is separately positioned on cranium On the temporal bone of bone two sides.Because bone conduction vibrator and bone-conduction microphone cannot transmit sound by vibration in the same time Do not obscure, so, at least one air conduction microphone is used for the present invention；At least one air conduction microphone is placed on On circuit main board, the function of directive pickup device is realized by microphone array design；It can be highly sensitive on fixed-direction The direction in ground collection sound, especially oral cavity.In addition, at least one bone-conduction microphone is also disposed in hair band bodies top Side, it can transmit sound than relatively thin skin contact with outside skull.In this way, when bone conduction vibrator is idle, it can To collect sound by bone-conduction microphone, to realize the purpose of noise reduction.Because of its principle for vibrating transmitting sound, ambient noise Bone-conduction microphone will not be interfered.In addition, bone-conduction microphone can conduct Mike with auxiliary air when bone conduction vibrator work Wind realizes a kind of function of detecting and offset environmental noise, as shown in figure 5, present system detects bone conduction vibrator just in work Make state, while bone-conduction microphone and air conduction microphone are all movable, however, they are detected without directly output Signal to be wirelessly connected module.Air conduction microphone detects ambient noise and the voice of user simultaneously, and osteoacusis Mike Wind can only detect the voice of the user generated by vibration due to the property of itself.Then, using correlation appropriate, and with adjustment The detection signal of preceding air conduction microphone subtracts the detection signal of bone-conduction microphone, and ambient noise signal can pass through Digital signal processing method is extracted.Then, the ambient noise being extracted can with air conduction microphone signal into Row synchronizes, and progress subtraction operation, the ambient noise that such air conduction microphone is collected into can be supported completely between them Disappear.Therefore, in the present invention, no matter whether bone conduction vibrator works, air conduction microphone either bone-conduction microphone Collected sound can achieve the purpose that elimination to ambient noise.This is also that present invention introduces two kinds of microphone types most Whole purpose.

Specifically, bone-conduction microphone of the invention only detects user voice signal A, and air conduction microphone detects The mixed signal C of user voice signal A and ambient noise signal B, i.e. C=A+B；Judge bone conduction vibrator input power whether More than threshold value (threshold value here refer to pre-entered by user or the threshold value of input power predetermined), if it is not, then by The signal that bone-conduction microphone detects can be obtained pure user voice signal A, and ambient noise signal B can ignore；Such as Fruit is then to carry out signal correlation operation, normalizes amplitude, and signal C and signal A are done subtraction and obtain normalized ambient noise Signal B, i.e. B=C-A；It is delayed to the mixed signal C that air conduction microphone detects, normalized ambient noise is believed Number B carries out amplitude adjustment, and the mixed signal C of delay and normalized ambient noise signal B are done subtraction, obtain pure voice Signal A, ambient noise signal B is eliminated at this time, and air transmitted and bone-conduction microphone, which combine, offsets during equipment send words The workflow of ambient noise terminate.

One of which is achieved in that in the present invention, and bone-conduction microphone and air conduction microphone can work alternately It carries out sending words.The trigger signal of switching depends on the size of the input power of bone conduction vibrator.It is passed by a bone predetermined The input power threshold value of oscillator is led to judge whether bone-conduction microphone should be activated.Fig. 6 shows the work flow diagram of the process. When bone-conduction microphone detection has an input signal, the input power that will do it a detection bone conduction vibrator first is sentenced It is disconnected.If input power is more than threshold value predetermined, mean that the bone conduction vibrator has occupied osteoacusis vibration.Cause This, it can trigger disabling bone-conduction microphone and vibration signal is transmitted to wireless communication unit but it is not closed, only It is that talking path is sent to interrupt, to avoid obscuring.And at the same time, it can activate air conduction microphone to replace osteoacusis Mike Hearsay transfer audio signal is to wireless communication unit, but during this, user speech that bone-conduction microphone can will be collected into It is normalized, and the voice and ambient noise mixed signal that are collected into normalized air conduction microphone do and subtract Method operation, and then obtain the normalized value of ambient noise.Then, another channel can receive the air conduction microphone of delay The resulting environment normalization noise of the mixture normalization signal and calculating collected does subtraction again, and final acquisition balances out environment and makes an uproar The air transmitted voice of sound, realizes the purpose of noise reduction.On the other hand, if the input power of bone conduction vibrator is lower than threshold value, Bone-conduction microphone is then activated to carry out sending words, by bone-conduction microphone transmission audio signal to wireless communication unit, at the same time, Air conduction microphone send talking path to be closed.After the present invention can provide ambient noise elimination under any circumstance in this way Voice communication.

The problem of this invention also solves skeletons, tissue attenuation signal.One disadvantage of bone conduction technology is existing It is not well solved in technology, here it is vibration signal frequency components to inhale in skull, temporal bone and other tissues Become difficult the conduction of high quality audio in the case where being stored in.Because these skeletons and musculature can be to not unisonances The signal of frequent section generates different degrees of decaying, that is to say, that and bone and musculature have selectivity to the decaying of audio, Therefore the vibration of different bone and tissue will absorb the component of different frequency.Even more noteworthy, the different physique of user, fat It is thin that such case can be made to become increasingly complex.This is difficult the audio frequency apparatus of bone conduction technology and air transmitted audio frequency apparatus Audio performance compares favourably.In existing bone conduction technology, overcoming the method for this human body attenuation effect is biography in osteoacusis It broadcasts and more signal amplitude surpluses is provided on path, to offset this decaying, or by selecting optimal bone conduction vibrator to connect The position of skin is touched to solve.But frequency dependence audio damping still occurs in the case where osteoacusis, travels to sense of hearing mind The signal of warp is not balanced, and signal fidelity can deteriorate.In addition, realizing by increasing signal amplitude, bone biography will lead to Oscillator vibration surrounding air is led, secondary air transmitted sound is caused, generates serious leakage sound, the individual that this will lead to user is hidden Private is leaked.This method is usually denounced in the prior art because user feel this so-called bone conduction technology just as It is to wear high-pitched speaker on ear side, can be sayed without individual privacy.Moreover, for wide-band vibration signal, also known as high guarantor True vibration signal, this method for increasing signal amplitude can make situation become more acute, too much for HD Audio The generation of decaying may generate audio distortions very serious.

Therefore, the present invention provides a kind of methods of different location multiplexing by bone and tissue, to make up, Loss during weighing apparatus audio transmission.

Ideally, since osteoacusis transmission function caused by vibrating is expected to the process of one flat decaying of characterization (constant attenuation and frequency) and single regular time delay.However, the vibration transfer function generated under actual conditions The signal of decaying and the response of a variable delay of amplitude asymmetry and frequency dependence is but provided.Therefore it to realize and tradition The identical performance of air transmitted audio parts, the present invention carries out the selection point of contact position using multiple osteoacusis electro-acoustic elements Collection is combined with signal strength recovery technology to compensate the declining with frequency selectivity as caused by bone and tissue absorption Reduction is answered.

During osteoacusis, when signal bandwidth is more than certain bandwidth threshold, frequency selective attenuation will occur. In order to compensate for its influence, the present invention proposes multiple bone conduction devices while acting on different positions, via each osteoacusis road The transmission function encountered in diameter must digital signal processor in it is balanced.This method in ideal conditions, if Before being detected by auditory nerve, the inverse function of each transmission function can be applied on the bone conduction device in each path signal When, the audio amplitude response being entirely detected will flatten smooth, and compensation propagation delay may be implemented, final vibration letter Number decaying can be eliminated.Wherein, digital signal balancing technique of the invention can use existing several digital equalising skills Art is realized, it is not limited to which certain specific digital equalising technology selects which kind of balancing technique, Ke Yigen as engineering construction It is selected according to actual conditions.The principle of the present invention is shown below in Fig. 7 and Fig. 8.

As shown in Figure 7 and Figure 8, the present invention constructs a multipath propagation model, and can generate signal decaying phase For the relationship of spread scope.The different amplitude versus frequencies that this model can reach auditory nerve by each road signal calculate Differential path loss, to find the presence of wave crest and null value due to caused by bone and tissue absorption.The present invention can With according to detection vibration signal intensity or some other performance index, such as：Distance, the thickness of tissue to bone pass Direction etc. is broadcast because usually selecting optimal contact skull/temporal bone different location to place bone-conduction microphone or osteoacusis vibration Son.By receiving or emitting vibration signal at least two different position, compensation bone may be implemented and tissue is made At vibration decaying effect.Fig. 7 shows the principle that multipath diversity vibration signal technology in the present invention send words, Fig. 7 In schematically show 4 different paths, respectively path 1, path 2, path 3 and path 4, by by osteoacusis Mike Different positions is arranged in wind, so that the bone-conduction microphone of different location receives vibration signal by different paths, these There is specific relationship, the tissue that Fig. 7 is schematically listed includes nose between the tissue different from human body of different paths Channel, nostril, mouth, tooth, tongue, vocal cords, tracheae and oesophagus.Fig. 8 shows multipath diversity vibration signal skill in the present invention Art carries out called principle, and 4 different paths, respectively path 1, path 2, path 3 are equally schematically shown in Fig. 8 With path 4, by the way that bone conduction vibrator to be arranged in different positions so that the bone conduction vibrator of different location pass through different roads Diameter sends out vibration signal, has specific relationship between the tissue different from human body of these different paths, Fig. 8 is schematically arranged Tissue out includes auricle, temporal bone, phonophore, external auditory canal, eardrum, Eustachian tube, cochlea and auditory nerve.

It is strong away from vibration signal different on discrete time in osteoacusis that Fig. 9 illustrates two different bone conduction device positions Degree.

In the present invention, because the placement location of multiple bone conduction devices for vibration signal intensity recovery technology extremely Close it is important, so bone conduction device placement location selection depend on vibration signal quality.Multiple bone conduction device conduction vibrations Influence of the dynamic path diversity formed for the osteoacusis path of frequency-dependent attenuation is as shown in Figure 10, and which illustrate passed by bone Increasing substantially for performance may be implemented in guiding path diversity.It is worth noting that, if identical osteoconductive energy is by existing Technology is realized, it is necessary to be realized by introducing additional but very big vibration signal level surplus, directly be will lead to Unacceptable serious leakage audio should and power consumption penalty.Figure 10 shows the gain of multipath diversity generation proposed by the present invention more In the surplus for having mended the decaying of vibration signal caused by the frequency dependence skeleton for needing to compensate in the prior art and tissue It is most of, that is to say, that introduce additional but very big vibration signal level surplus without going through the prior art to carry out Compensation, would not also generate serious leakage audio should and power consumption penalty.

In the present invention, the bone conduction device of multiple redundancies is placed specific, different position and skull or temporal bone Skin is contacted, to improve the quality of the robustness in osteoacusis path and the vibration signal path of carrying audio.In Figure 11 a and It is illustrated in Figure 11 b compared with the prior art, a specific embodiment of the invention.In the present invention, required transmitting (bone Conduct oscillator) and reception (bone-conduction microphone) side at least two devices of needs.

As shown in fig. 11a, the prior art does not provide any robustness for osteoacusis placement location or quality improvement machine System, therefore, the prior art merely provide a basic, simple osteoacusis path.That is, in the prior art One single bone-conduction microphone is only set, and vibration signal send words by single-pathway, while single osteoacusis is only arranged Oscillator, vibration signal send words by single-pathway, although schematically illustrating multiple tissues in Figure 11 a, including nose is logical Road, nostril, mouth, tooth, tongue, vocal cords, tracheae, oesophagus, auricle, temporal bone, phonophore, external auditory canal, eardrum, Eustachian tube, cochlea And auditory nerve, but the prior art does not consider the problems of these tissue deamplifications.

However, the present invention can provide the multichannel of receiving side (bone-conduction microphone) and emitting side (bone conduction vibrator) simultaneously Diameter diversity, and additional system robustness is provided.The present invention compensates amplitude by Digital Signal Processing multipath vibration signal The loss and propagation delay of degree, can substantially improve the audio quality of bone conduction technology.The selection of transmitting diversity and contact position The performance of bone-conduction microphone can be greatlyd improve.The present invention allows bone conduction technology to match in excellence or beauty sky by multipath diversity The prior art of gas conduction audio.As shown in figure 11b, the present invention provides multiple bone-conduction microphones and is separately positioned on difference Position, schematically illustrate the embodiment with N number of bone-conduction microphone in Figure 11 b, the bone of position 0 be respectively set The bone-conduction microphone RX1 ... ... of position 1 is arranged in conduction microphone RX0, and the bone-conduction microphone RXN of position N is arranged in, This N number of bone-conduction microphone constitutes vibration signal multipath transmitter system, and multiple bone-conduction microphones carry out multipath diversity biography It leads.Similarly, the present invention also provides multiple bone conduction vibrators and it is separately positioned on different positions, in Figure 11 b illustratively The embodiment with M bone conduction vibrator is shown, the bone conduction vibrator RX0 ' in position 0 ' is respectively set, is arranged in position The bone conduction vibrator RXM of position M is arranged in 1 ' bone conduction vibrator RX1 ' ... ..., this M bone conduction vibrator constitutes vibration letter Number called mechanism of multipath, multiple bone conduction vibrators carry out multipath diversity conduction.

Multipath vibration signal diversity in the present invention is realized by digital signal processing algorithm.For example, it is assumed that two A bone conduction vibrator is configured to multipath diversity, and as shown in figure 12, digital audio input signal passes through the limited arteries and veins of digital signal Punching response (Finite Impulse Response, FIR) filtering frequency divider is transported to digital analog converter, by digital analog converter Signal is transferred to low frequency bone conduction vibrator driver and high frequency bone by (Digital to Analog Converter, ADC) respectively Conduct oscillator driver.Low frequency bone conduction vibrator driver issues low-frequency vibration signal component, and high frequency bone conduction vibrator is driven Dynamic device issues high-frequency vibration signal component.Low-frequency vibration signal component s₀It is passed on the specific position 0 optimized by bone The transmitting of oscillator TX 0 is led, at the same time high-frequency vibration signal component s₁Then on another position 1 by bone conduction vibrator TX1 into Row transmitting.The binaural nerve of user is then used as receiving side, can be identified as left ear auditory nerve RX0 and auris dextra sense of hearing mind Through RX1, they pass through the transmission function h00, h01, h10 and h11 in four possible osteoacusis paths to being fixed on position respectively The signal that 0 bone conduction vibrator TX0 and the bone conduction vibrator TX1 for being fixed on position 1 emit is received, and thus forms one Osteoacusis path matrix, is identified as H.

For balanced and extraction emission source TX0 and TX1 vibration signal s₀And s₁, it is necessary to osteoacusis path matrix H is carried out Estimation.It can be calculated by following equation (1) in the received osteoacusis vibration signal of input terminal institute of each receiving side：

r₀=h₀₀s₀+h₁₀s₁

r₁=h₁₀s₀+h₁₁s₁ (1)

Wherein, r₀And r₁Respectively indicate the vibration signal that the receiving side of auditory nerve receives.Therefore, of the invention to pass through Osteoacusis path diversity techniques can be expressed as in the vibration signal that auditory nerve end obtains

Therefore, the inverse function of path transfer function [H] can be applied by Digital Signal Processing at transmiting signal source [S] On, i.e., become [H] by the transmiting signal source that the present invention compensated^-1·[S].It follows that by with the application of the invention, in the sense of hearing The vibration signal that nerve acquires is [R] '

[R] '=[H] [H]^-1[S]=[S]

By above formula it is found that through the invention, what the vibration signal of emitting side can be lossless is transmitted to receiving side Auditory nerve, to realize the audio transmitting of high-fidelity.Osteoacusis path diversity and hair for bone-conduction microphone (reception) The principle penetrated is identical, and details are not described herein again.

The problem of leaking sound this invention also solves bone conduction technology.In all bone conduction technologies, audio is by vibration Signal transmitting in bone (solid) is realized.As long as the solid that is touched on direction of vibration can transmit Sound.So in osteoacusis hair band design process, because the structure of fixed bone conduction vibrator is constituted using solid, Also the phenomenon that vibration can be transmitted, or even the air of surrounding is driven to generate secondary vibration, ultimately cause leakage sound.So Hen Duoxian Technology thinks that leaking sound is that osteoacusis is difficult avoid and solve problem.The prior art has been devoted to optimization osteoacusis vibration The research of dynamic generation, control and elimination.But all solid vibrations can all generate sound, would not if do not vibrated There is passing to for sound, bone conduction technology, which cannot achieve, completely eliminates vibration.Therefore, the present invention is directed to the intrinsic spy of bone conduction vibrator Property innovated, propose it is a kind of will vibration to the method minimized, this only vibration technology can completely eliminate osteoacusis Hair band leaks the problem of sound.The vibration of usual bone conduction vibrator is axial, that is to say, that the vibration signal on the direction in axle center accounts for According to dominating, the vibration on the direction orthogonal with axle center is weaker.So the present invention is concentrated to the non-contact skin side on axis direction Vibration signal only shaken, come realize only vibration eliminate leakage sound effect.Because of influence of the vibration for leakage sound on non axial It is smaller, so ignoring its influence.

The core of only vibration technology in the present invention is combined by metal layer and semisolid to eliminate interference vibration (i.e. Lead to the vibration of osteoacusis hair band leakage sound).Because certain specific semisolids have good only vibration performance, combined by it good Good conduct vibrations metal medium, is only shaken by the isolation to bone conduction vibrator.The present invention by it is compound only vibration layer and Acoustical cotton layer, which damps leakage sound vibration, only shakes.Compound only vibration layer is highdensity damping rubber layer in the present invention, and surface is attached Aluminium foil constitute, can to it is compound only vibration layer be overlapped, superposition quantity according to its inhibit osteoacusis leakage sound effect determine, tool Standby barrier, the effect of absorption of noise.There can also be the acoustical cotton layer of one layer of rubber and plastic material on the outside of compound only vibration layer, using bubble Closed pore design, is mainly used for sound-absorbing.Being superimposed order is：Compound only vibration layer is close to bone conduction vibrator, and acoustical cotton layer is close to compound stop Shake layer.

As shown in figure 13, bone conduction vibrator of the invention includes metal shell 134, the oscillator connecting with metal shell 134 Element 1311, the side of metal shell 134 are provided with audio input terminal 133, oscillator element 1311 and audio input terminal 133 Between connected by audio wire 131；The lower section of metal shell 134 is provided with external semimetal layer 135 and external semi-solid layer 136；Outer semimetal layer 135 and external semi-solid layer 136 constitute external compound only vibration layer, the lower section setting of external compound only vibration layer There is acoustical cotton layer 1.The outer diameter of oscillator element shown in Figure 13 is 13mm, is just suitble to auricle closing, from oscillator element 1311 The vertical height of outermost edges to external semimetal layer 135 is 10mm, and the outer diameter of metal shell 134 is 18mm.

The present invention, which damps leakage sound vibration by compound only vibration layer and acoustical cotton layer, only to shake, that is, solid vibration When, the energy for vibrating solid is dissipated in damping layer as much as possible.Damping refers to the relative motion for hindering object and fortune Energy be converted into thermal energy or it is other can be with dissipation energy.Damping can reduce the resonance amplitude of mechanical structure, reduce because of machinery Acoustic radiation caused by vibrating reduces osteoacusis hair band and leaks sound.When osteoacusis hair band works, for leaking sound signal, passed when along bone The vibration that certain frequency can be generated when oscillator center of gravity axis direction collides metal conductive layers device is led, because metal is good Conduct vibrations medium, axial vibration signal is uniformly distributed in can as far as possible on its area, so the vibration on unit area Dynamic signal, which is equivalent to, to be averaged and reduces, but is not absorbed.At the same time, metal layer and semi-solid layer closely paste Close, the vibration signal on metal is laminated can be equably transmitted on semi-solid layer, if metal and semisolid constitute it is compound Layer does not have external force, and the vibration of bone conduction vibrator excitation will gradually decay, and the speed of decaying depends on subtracting for semisolid material Width will obtain following formula according to Newton's law:

Quality+resistance+elastic force=0

If ignoring amount of decrease to disregard, the intrinsic frequency of available semi-solid layer is as follows:

Wherein, f₀Indicate the intrinsic frequency of semi-solid layer；The spring rate of C expression semi-solid layer；M indicates semi-solid layer matter Amount.When the impact force of vibration is far from center of gravity, semi-solid layer can generate twisting vibration in three axis, and respective angular frequency is:

Wherein, ω_DIndicate angular frequency；C_VIndicate torsion stiffness；J indicates inertia.

The spy that there is semi-solid layer in the present invention resonance that will be gradually increased to be reduced to certain level under normal circumstances Property, the isolation of semi-solid layer stops efficiency of shaking equal to excited frequency/intrinsic frequency and is:WhenWhen, exciting force will It reduces and is far not equal to intrinsic frequency, semi-solid layer will play the effect of isolation vibration, and as η=3, semi-solid layer only shakes Effect is up to 80%, that is to say, that only 20% exciting vibration is being conducted.Therefore, the semi-solid layer in the present invention can be with Play the role of weakening, absorbing instead of metal spring in the prior art, main performance requirement is in Static stiffness, dynamic stiffness, resistance to In long performance.

Semi-solid layer in the present invention is thick substances between a solid and a liquid, has following characteristics：

1, it is combined by multiple material, same shape can possess different performances by material adjustment.

2, the friction between semi-solid layer interior molecules makes it possess certain damping capacity, that is, the hysteresis quality that moves (by The deformation hysteresis of semi-solid layer is in the stress of semi-solid layer during power).

3, semi-solid layer can all generate different coefficient of elasticity in compression, shearing, drawing process.

The material of semi-solid layer is configured to rubber in the present invention.Because osteoacusis hair band leakproof sound requires greatly damping and amortization, So butyl rubber (IIR) material for having preferable damping capacity is optimal semisolid material.It can alleviate leakage sound vibration The power dispersed, and biggish cohesive force will not be generated.But the present invention is not limited to butyl rubber (IIR) material, Its available rubber is natural rubber (polyisoprene, NR), butadiene-styrene rubber (SBR), butadiene rubber (BR), neoprene (CR), isoprene rubber (IR), nitrile rubber (NBR), EP rubbers (EPDM), hydrogenation nitrile rubber (HNBR) etc..

In addition to semi-solid layer in the present invention, the concept of metal layer is also introduced, it combines with semi-solid layer and may be implemented One composite layer (i.e. compound only vibration layer), this composite layer, can be by multiple compound as basic only vibration leakproof sound unit The mode of layer superposition realizes the elimination of leakproof sound.Metal layer is aluminium foil or copper foil, but be not limited to that both metals. It is placed on inside bone conduction vibrator moreover, this composite layer can both design, also can be set on the outside of bone conduction vibrator.Institute With at least one composite layer of the present invention carries out the operation of axial only vibration inside or outside bone conduction vibrator.Generally speaking, this Composite layer prevents the principle of osteoacusis leakage sound as follows：

1, homogenization vibration：This good conduct vibrations medium by metal layer, can be original axial high intensity Vibration signal is evenly distributed on a bigger area, so the vibration signal of unit area is actually to reduce.

2, vibration is absorbed:Composite layer of the invention can be used for the connection of bone conduction vibrator internal vibration element and shell, It can be described as internal composite layer.Internal vibration element is vibration source under this state, and the effect of internal composite layer is to absorb it in axial direction The vibration generated when upper fitting shell, avoids that the outside that sound is transmitted to bone conduction vibrator will be leaked, while also can slightly reduce inside The vibration of vibrating elements itself.The outer diameter of internal composite layer is less than the outer diameter of bone conduction vibrator.

3, abatement vibration:Composite layer of the invention can be used for the connection between bone conduction vibrator and hair band frame, can To become external composite layer, entire bone conduction vibrator is vibration source under this state, and the effect of external composite layer is that osteoacusis shakes The vibration that son is generated with hair band frame acts on abatement rapidly by high-damping, prevents vibration from generating by hair band frame vibration air Leak sound.The outer diameter of external composite layer is more than or equal to the outer diameter of bone conduction vibrator.
