When the frequency of external sound wave is identical with the resonant frequency of the noise elimination structure, covibration, amplitude will be produced
Maximum is reached, the gas in the noise elimination structure moves reciprocatingly under acoustic wave action, by friction and damping action, make one
Acoustic energy is divided to be converted to thermal energy consumption.When the frequency of external sound wave leaves the resonance frequency value farther out, sound deadening capacity drastically declines.
For example shown in Fig. 3, dotted line (curve l) is the frequency response chart for being not provided with the noise elimination structure, and solid line (curve 2) is setting
The frequency response chart of the noise elimination structure.The In-Ear Headphones can force down a certain frequency range by arranging the noise elimination structure
Frequency response, obtain closer to require sound.It should be appreciated by those skilled in the art, in order to obtain close requirement
Sound, the noise elimination structure is readily adaptable for use in other kinds of earphone to reduce the frequency response of certain frequency range.
Preferably, as described in Figure 2, the noise elimination structure is made for convenience, second acoustic conducting pipe is to be arranged on described the
Through hole 7 on the tube wall of one acoustic conducting pipe 5.The through hole 7 connects the resonant cavity 6 and first acoustic conducting pipe 5.The through hole 7
The noise elimination structure is collectively formed with the resonant cavity 6.When the frequency of external sound wave reaches or be close to the noise elimination structure
During resonant frequency, the gas in the through hole 7 is moved back and forth, by the through hole 7 under acoustic pressure effect as piston
The friction of inner surface and damping action, make a part of acoustic energy be converted into thermal energy consumption.
It is further preferred that as depicted in figs. 1 and 2, it is contemplated that the outward appearance of the In-Ear Headphones, the ring of the resonant cavity 6
Around the outer surface of first acoustic conducting pipe 5.One end of the resonant cavity 6 is connected with the shell 1, and the resonant cavity 6 is in addition
One end can extend to the marginal position of first acoustic conducting pipe 5.It is so designed that, the resonant cavity 6 can be avoided to surround described
The local outer surface of the first acoustic conducting pipe 5 so that the outer surface out-of-flatness of the In-Ear Headphones, so as to affect the product body of user

It is anti-Wherein, SbFor the cross-sectional area of the passage of the second acoustic conducting pipe 7, lbFor second acoustic conducting pipe 7
Length, VbFor the volume of the resonant cavity 6.Determine natural frequency f of the noise elimination structurebAfterwards, then calculate and meet natural frequency fb
The cross-sectional area S of the required passage of the second acoustic conducting pipe 7b, length lbWith volume V of the resonant cavity 6b, according to the chi for calculating
It is very little making the noise elimination structure.
Optionally, the sound deadening capacity of the noise elimination structureWhereinF is the frequency of external sound wave, and S is the cross-sectional area of the passage of the first acoustic conducting pipe 5.When external sound
When the frequency of ripple is f, the sound deadening capacity T of the noise elimination structureLIncrease than z with frequency and reduce rapidly, the sound deadening capacity TLWith β value
For direct ratio.Therefore, for the frequency range that noise elimination structure described in broadening can eliminate the noise, it is larger that β value to be arranged.If described first
The cross-sectional area S of the passage of acoustic conducting pipe 5 is fixed, then volume V of the resonant cavity 6bWhat is arranged is larger to eliminate the noise described in broadening
The frequency range that structure can eliminate the noise.
Preferably, as shown in Fig. 2 to ensure that the theoretical noise elimination value of the noise elimination structure keeps one with the noise elimination result of reality
Cause, second acoustic conducting pipe 7 is arranged on the middle part of the noise elimination structure.Because the gas in second acoustic conducting pipe 7 is in sound wave
Under pressure effect, move back and forth as piston.It is so designed that avoiding second acoustic conducting pipe 7 is arranged on the noise elimination structure
Marginal position, gas in the resonant cavity 6 by irregularly flowing after second acoustic conducting pipe 7.
Preferably, as shown in Fig. 2 the cross-sectional area of the passage of the second acoustic conducting pipe 7 is less than or equal to first sound
/ 10th of the cross-sectional area of the passage of conduit 5.For example, the cross-sectional area of the passage of the first acoustic conducting pipe 5 of existing earphone generally sets
Put between 10-50 square millimeters, accordingly, the cross-sectional area of the passage of the second acoustic conducting pipe 7 is less than 1-5 square millimeters.
This kind of structure design can avoid the cross-sectional area of the passage of the second acoustic conducting pipe 7 excessive, cause sound wave just can lead to easily
Second acoustic conducting pipe 7 is crossed into the resonant cavity 6, and then affects the sound performance of the In-Ear Headphones.And described disappear
Acoustic form is relatively small to the friction of gas and damping action, does not also reach the soundproof effect of anticipation.
Preferably, as shown in Fig. 2 the In-Ear Headphones also include ear muff 8, the ear muff 8 fits in user
Auditory meatus.The ear muff 8 is in hollow structure, and the hollow structure runs through the ear muff 8.The ear muff 8 is located at first acoustic conductance
Such as away from one end of the loudspeaker monomer 2, one end of described ear muff 8 can be with first acoustic conducting pipe 5 away from described for pipe 5
The end surface of loudspeaker monomer 2 connects, and the other end of the ear muff 8 can be set in the surface of first acoustic conducting pipe 5.
The In-Ear Headphones are fitted by the ear muff 8 with the auditory meatus of user, can more efficiently intercept external noise.
Preferably, to enable the In-Ear Headphones to adjust the frequency response of multiple frequency ranges, the In-Ear Headphones set
There are multiple noise elimination structures.It is further preferred that multiple noise elimination structures have different resonant frequencies.When external sound wave
Frequency be close to wherein any one fixed frequency when, the In-Ear Headphones can adjust its frequency response, with obtain more
It is close to desired sound.Thus, multiple noise elimination structures can adjust the frequency response of multiple different frequency ranges, it is to avoid only arrange
The frequency range that can be adjusted during one noise elimination structure is excessively narrow.
Alternatively, when the flow in the one the second acoustic conducting pipe 7 is larger, multiple noise elimination structures may be configured as phase
Same resonant frequency.For example, the body of the cross-sectional area, length and multiple resonant cavities 6 of multiple passages of second acoustic conducting pipe 7
Product can be of the same size, so that multiple noise elimination structures have identical resonant frequency.Due to the rising tone
The cross-sectional area of the passage of conduit 7 is less than 1/10th of the cross-sectional area of the passage of the first acoustic conducting pipe 5, if first sound
The cross-sectional area of the passage of conduit 5 is fixed, then the cross-sectional area of the passage of the second acoustic conducting pipe 7 has maximum.When first sound
When flow is larger in the passage of conduit 5, only less second acoustic conducting pipe 7 of one channel cross-sectional area of setting can not reach requirement
Soundproof effect.Therefore, it can arrange multiple noise elimination structures with same resonance frequency to obtain preferable soundproof effect.
