Specific implementation mode
Figure 1A be according to the utility model an embodiment have lose heart groove ear-canal earphones stereoscopic schematic diagram,
Figure 1B is the upper schematic diagram of the ear-canal earphones of Figure 1A, and the ear-canal earphones that Fig. 1 C are Figure 1B are illustrated along the section of line A-A
Figure.
Figure 1A and Figure 1B are please referred to, the ear-canal earphones 100 for the groove that loses heart that have of the present embodiment include a shell 110.
Shell 110 has the discouraged groove G10 of one first bleeder port A12 and one.The groove G10 that loses heart extends the outer surface S10 of shell 110
Upper and the first bleeder port A12 of connection.
Fig. 1 C are please referred to, the ear-canal earphones 100 of the present embodiment further include a horn single body 120.Shell 110 also has one
Cavity C 10 and a sound mouth P10.Horn single body 120 is configured at cavity C 10.Before cavity C 10 is divided into one by horn single body 120
Cavity C 12 and a rear chamber C14.Sound mouth P10 is connected to front chamber C12 with the first bleeder port A12.
When the ear-canal earphones 100 of the present embodiment are placed in the external ear of user, ear-drum and the horn single body 120 of user
Between air sequentially flowed to outside shell 110 by sound mouth P10, front chamber C12 and the first bleeder port A12, and then flow
To the external world.Therefore, the ear-drum of user can't not feel well because of by air extrusion.In addition, horn single body 120 is not yet
It can be deformed by air extrusion and cause audio distortions.
In addition, because the shape of the external ear of each user is variant, in the external ear that ear-canal earphones 100 are placed in, have
The external ear of a little users may cover the first bleeder port A12.But in addition to the first bleeder port on the shell 110 of the present embodiment
Except A12, also there is the discouraged groove G10 of the first bleeder port A12 of connection.Thus, even if the external ear of each user
Shape is variant, and entire discouraged groove G10 is also greatly reduced by the probability that the external ear of user covers.Therefore, it can be ensured that use
Air between the ear-drum and horn single body 120 of person can sequentially by sound mouth P10, front chamber C12, the first bleeder port A12 and be let out
Channeling slot G10 and flow to outside shell 110, and then flow to the external world.
The reason of ear-canal earphones 100 of the present embodiment are referred to as duct-type is a part of volume of ear-canal earphones 100
It can be placed into duct from auricle, and the end of duct is exactly eardrum.Therefore horn single body 120 can go deep into duct and approach
Eardrum is sufficient for demand of the user for volume as long as smaller driving power.In addition, horn single body 120 and shell
110 can also hinder environmental noise to be transferred to eardrum, therefore generate the effect of passive anti-noise, and the fidelity of sound also can be improved.
The ear-canal earphones 100 of the present embodiment can further include a microphone 130, be configured at front chamber C12, and be located at sound
Between mouth P10 and horn single body 120.Thus, which microphone 130 can go deep into duct and close to eardrum to detect institute in duct
The sound wave of transmission.When ear-canal earphones 100 wear the ear in user and go deep into duct, sound mouth P10 will be faced and be connect
The eardrum of nearly ear, and horn single body 120 can hinder environmental noise to be transferred to microphone 130 with shell 110, therefore generate passively
Fidelity when 130 radio reception of microphone also can be improved in the effect of anti-noise.In addition, because of microphone 130 very close to the drum of user
Film, sound wave caused by caused vibrophone delicately can be detected and collected by microphone 130 when user speaks, and
The sound that user sends out can also be transferred in duct and be collected by microphone 130 by the bone of people well.Furthermore because
The design of first bleeder port A12 and discouraged groove G10, also can avoid microphone 130 is influenced by excessive air pressure and is generated
Whister-type noise.
The average diameter of the duct of the mankind is more than 8mm, and the diameter of the microphone 130 of the present embodiment is, for example, less than to be equal to
6mm, therefore microphone 130 can go deep into duct and close to eardrum.
In the present embodiment, horn single body 120 is, for example, that cavity C 10 is divided into the front chamber C12 to not exchange information with after
Cavity C 14.Therefore, horn single body 120 can effectively prevent environmental noise from being transferred to microphone 130 from rear chamber C14.This
Outside, the discouraged groove G10 of the present embodiment can be from the first bleeder port A12 backwards cavity C 14 direction extend.Lose heart groove
The chance that the part of the G10 direction extensions of cavity C 14 backwards is covered by the inner ear of user is smaller, therefore it is easy to ensure that loses heart logical
Road it is smooth.Discouraged groove G10 is substantially to have bottom, that is, the depth for the groove G10 that loses heart is less than at its place
The thickness of shell 110, to avoid the possibility that ambient noise is passed in shell 110 is excessively increased.In addition, the duct of the present embodiment
Formula earphone 100 can further include an ear pad 140, be configured at outside the sound mouth P12 of shell 110.It can using the flexible deformation of ear pad 140
The auricle contour for adapting to different users, provides comfortable wearing feeling, and completely cut off external sound and promote sound quality.
The shell 110 of the present embodiment includes the front housing 112 being combined and a rear shell 114.Front chamber C12 is located at loudspeaker list
Between body 120 and front housing 112.Rear chamber C14 is between horn single body 120 and rear shell 114.The groove G10 that loses heart is let out with first
Stomata A12 is located at front housing 112.For shell 110 using the design of two-piece type, main consideration is the complexity on assembling procedure, but
The utility model is not limited to this.In addition, the shell 110 of the present embodiment also has one second bleeder port A14, it is connected to rear chamber
C14 and the external world.
Fig. 2A is the three-dimensional signal according to the ear-canal earphones with the groove that loses heart of another embodiment of the utility model
Figure, and Fig. 2 B are the diagrammatic cross-sections of the ear-canal earphones of Fig. 2A.Fig. 2A and Fig. 2 B are please referred to, the present embodiment has the ditch that loses heart
The ear-canal earphones 200 of slot are roughly the same with the ear-canal earphones 100 of Fig. 1 C, at the difference for only illustrating the two herein.This implementation
The discouraged groove G20 of example is that the direction from the first bleeder port A12 towards sound mouth P10 extends.It will be such as in fact, losing heart groove G20
What extends, and can be adjusted according to design requirement, as long as can reduce what discouraged groove G20 was entirely covered by the inner ear of user
Possibility is all right.In addition, if the part for the groove G20 that loses heart extends to the part that can be covered by ear pad 140, because of ear pad 140
It is not likely to be deformed into and fills up discouraged groove G20, it helps keep the smooth of bleed passage.
In conclusion in the ear-canal earphones with discouraged groove of the utility model, the gas between earphone and external ear
Pressure can be discharged via sound mouth, front chamber and the first bleeder port.In this way, can express when solution user wears earphone may experience
Sense of discomfort, and best sound quality is provided.In addition, when being equipped with microphone in ear-canal earphones, microphone is also can avoid by gas
The problem of pressure influences and sends out whister-type noise.
Although the utility model has been disclosed in conjunction with above example, it is not limited to the utility model, is appointed
What those of ordinary skill in the art can make a little more without departing from the spirit and scope of the utility model
Dynamic and retouching, therefore the scope of protection of the utility model should be subject to what the appended claims were defined.
