Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
For sound transmission, technical staff describes that device hinders the size of sound transmission ability usually using acoustic impedance.
Acoustic impedance can be indicated by following publicity: Z=R+j ω L, wherein R indicate because in air-flow and device wall friction due to the acoustic resistance that generates, j
ω L indicates the acoustic reactance as caused by acoustic mass, and L indicates the spread length of sound in a device.
Shown in referring to Fig.1~2, a kind of In-Ear Headphones, including shell 1 are present embodiments provided, and be set in shell 1
Chu Yin mechanism and deflector, shell 1 include rear cover 3 and enter the front cover 2 of ear canal for leading note, Chu Yin mechanism passes through acoustic conductance
It manages and is connected to the sound mouth being set on front cover 2, wherein Chu Yin mechanism includes bass unit 4, alto units 5 and voice unit
6, the bass unit 4, alto units 5 and voice unit 6 are exported by acoustic conducting pipe 11 with the bass being set on front cover 2 respectively
41,61 connection of middle pitch outlet 51 and high pitch outlet；Deflector includes the first conducting element, and one end of the first conducting element is by setting
The first through hole 21 set on front cover 2 is connected to ear canal, and the other end is connected to by interface with the second conducting element, and the second conducting element is set
It sets in deflector end and is in communication with the outside by the second through-hole 31 for being arranged on rear cover 3；First conducting element and second is led
Stream part is respectively provided with the first acoustic impedance Z1With rising tone impedance Z2, ear canal itself has into sound impedance Z0, therefore need to make into sound impedance
Z0Less than the first acoustic impedance Z1And/or rising tone impedance Z2。
First acoustic impedance Z1Including the first acoustic resistance R1With the first acoustic reactance j ω L1；And rising tone impedance Z2Including the rising tone
Hinder R2With the second acoustic reactance j ω L2；And enter sound impedance Z0Including entering speech resistance R0With enter the anti-j ω L of speech0；Due to Hi-Mid frequency
It is higher, so deflector itself is stronger to the blocking of Hi-Mid, therefore, only it need to allow deflector that can also be formed to bass effectively
Barrier just can form preferable reservation to bass；Again because the ω of bass is smaller, acoustic reactance role is smaller, therefore sound
When sound is propagated in conducting element, bass formed and be obstructed, need to do conducting element is longer, to increase air-flow and conducting element
Contact area, so that entering speech resistance R0Less than the first acoustic resistance R1And/or the second acoustic resistance R2, thus reduce conducting element to bass
Loss.
In the present embodiment, the first conducting element includes elongated flow directed catheter 7, to have biggish first acoustic resistance R1.It leads
Conductance pipe 7 spirals setting within the case 1, and one end is connect with front cover 2, and the other end is connect with the second conducting element；Pass through high-precision 3D
The mode of printing can directly get the flow directed catheter 7 to spiral inside earphone, to make full use of the inner space of shell 1.
Second conducting element includes that waterproof ventilated membrane 8, waterproof ventilated membrane 8 and the first conducting element pass through orifice, interface packet
The cylinder cavity 10 that 31 inside of the second through-hole is set is included, cylinder cavity 10 is connected to deflector, and waterproof ventilated membrane 8 is fixed on
In cylinder cavity 10, air-flow can be adjusted through the fast of waterproof ventilated membrane 8 by adjusting the stomata density on waterproof ventilated membrane 8
Slowly, to adjust the second acoustic resistance R2Size, to further decrease the bass loss in deflector.
Preferably, the inlet end of flow directed catheter 7 be equipped with pluggable metal capillary 211, the metal capillary 211 it is interior
Diameter is less than the internal diameter of flow directed catheter 7.The opening at first through hole 21 can be made to narrow in this way, prevent the foreign matters such as earwax from entering,
Even if into also metal capillary 211 quickly can be extracted, facilitated and dredged and cleaned.
Preferably, Air Filter 9 is additionally provided in cylinder cavity 10, Air Filter 9 is fixed on the outside of waterproof ventilated membrane 8.Due to
Deflector end is in communication with the outside by the second through-hole 31, and the probability for contacting water and dust is higher, therefore by saturating in waterproof
Water proof and dust proof can effectively be carried out by adding Air Filter 9 on the outside of air film.
The present embodiment is using internal diameter to prepare flow directed catheter 7 for the material of 1mm, when people puts on the In-Ear Headphones audition
When happy, in ear extra air can from first through hole 21 enter flow directed catheter 7, using draining ventilated membrane 8 and Air Filter 9 from
Second through-hole drains into the external world, to realize air pressure balance in ear and extraneous, reduces uncomfortable to people's bring.
Fig. 3 is magnitude of sound-frequency response curve schematic diagram that different type earphone measures at sound mouth.Such as Fig. 3 institute
Show, a line represents magnitude of sound-frequency response curve of common equilibrium air pressure earphone in the market, and flow directed catheter is only added in the expression of b line
Magnitude of sound-frequency response curve when 7, c line indicate sound width when flow directed catheter 7 had not only been added but also waterproof ventilated membrane 8 is added
Value-frequency response curve, d line indicate magnitude of sound-frequency response curve of common pleasant earphone in the market.It can be from Tu Zhongguan
To see, d line bass holds up to the function of not having air pressure in balance ear still, and a, b, c line are provided with equilibrium air pressure function, and
The effect that the earphone that c line represents retains bass is best.
The deflector that ear canal is connected to the external world is balanced the air pressure in ear canal, and the flow guiding machine by setting by the present invention
Structure includes biggish first conducting element of acoustic impedance and the second conducting element, can effectively reduce bass loss, meets user and appreciates sound
Happy demand.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.Those skilled in the art's made equivalent substitute or transformation on the basis of the present invention, in the present invention
Protection scope within.Protection scope of the present invention is subject to claims.
