Description
Technical field
The utility model relates to the tuning structures of ear phone technology field, especially PlayGear Stealth.
Background technique
Known, the pronunciation principle of earphone is sufficiently complex, needs close tuning that could perfectly adjust out sound quality, here
There is very big relationship with air sound chamber, most earphone requires specially to bore a sound regulating hole in the rigging position of loudspeaker, makes sky
Gas flows into, so that sound wave be allowed to propagate in air, primarily to increasing the amplitude of sound, keeps sound quality limpid；And each earphone
Shell requires specially to punch tuning, and the expense and time-consuming of this process are huge.
Summary of the invention
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of acoustics tuning structure of earphone, obtain
Ideal tuning effect is obtained, and structure is simple, it is simple for production.
In order to achieve the above objectives, the utility model adopts the following technical solution:
A kind of acoustics tuning structure of earphone has earphone case and is placed in the intracorporal loudspeaker of ear casing, the earphone case
With the preceding sound column for filling in ear, sound outlet hole is equipped with inside preceding sound column, group sets Air Filter on the front port of sound outlet hole；The sound out
Also group sets acoustic damping tuning part on hole.
Above scheme is further: the acoustic damping tuning part and Air Filter are installed along on hollow plug connector,
The front port of the sound outlet hole of sound column before the plug connector is inlaid in.
Above scheme is further: the plug connector and preceding sound column are coaxial, and one end of plug connector has matching sound outlet hole hole
The caulked section of diameter, the other end of plug connector have the inner groovy of limited ring dais and indent, are embedded in acoustic damping tuning in inner groovy
Part and Air Filter.
Above scheme is further: the acoustic damping tuning part is sheet body form, acoustic damping tuning part and Air Filter
Between layered arrangement.
Above scheme is further: the outer diameter of the acoustic damping tuning part and Air Filter is in the same size.
Compared with prior art, on the basis of not destroying earphone case, only group is set the utility model on sound outlet hole
Acoustic damping tuning part, the sound tuning which spreads out of sound outlet hole obtain ideal tuning effect, and structure
Simply, simple for production, the cost performance of significant increase earphone.
Detailed description of the invention:
Attached drawing 1 is the utility model one example structure schematic diagram；
Attached drawing 2 is the connector structure schematic diagram of Fig. 1 embodiment；
Attached drawing 3 is the plug connector one form and preceding sound column attachment structure schematic diagram of Fig. 1 embodiment；
Attached drawing 4 is the plug connector of Fig. 1 embodiment secondly form and preceding sound column attachment structure schematic diagram.
Specific embodiment:
Make furtherly below with reference to technical effect of the attached drawing to the design of the utility model, specific structure and generation
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
It should be noted that term " on ", "lower", "left", "right", "vertical", " water in the description of the present invention,
It is flat ", "inner", the direction of instructions such as "outside" or the term of positional relationship be direction based on the figure or positional relationship, this is only
It is merely for convenience of describing, rather than indication or suggestion described device or element must have a particular orientation, with specific side
Position construction and operation, therefore should not be understood as limiting the present invention.In addition, term " first ", " second ", " third ",
" the 4th " is used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
Refering to fig. 1, shown in 2,3,4, a kind of acoustics tuning structure of the utility model in relation to earphone has earphone case 1
And it is placed in the intracorporal loudspeaker (not shown) of ear casing, which, which has, fills in the preceding sound column 11 of ear, in preceding sound column 11
Portion is equipped with sound outlet hole 111, and group sets also group on Air Filter 2 and sound outlet hole 111 and sets acoustic damping on the front port of sound outlet hole 111
Tuning part 3.As a result, on the basis of not destroying earphone case 1, only increase group sets acoustic damping tuning part 3 on sound outlet hole,
The sound tuning spread out of using acoustic damping tuning part 3 to sound outlet hole obtains ideal tuning effect, and structure is simple, system
Make easy, the cost performance of significant increase earphone.
Shown in Fig. 1,2,3,4, in the present embodiment, the acoustic damping tuning part 3 is installed along with hollow with Air Filter 2
On plug connector 4, the front port of the sound outlet hole of sound column 11 before which is inlaid in.Further, the plug connector 4 and preceding sound
Column 11 is coaxially connected, and one end of plug connector 4 has the caulked section 41 in matching sound outlet hole aperture, and the other end of plug connector 4 has limit
The inner groovy 43 of position land 42 and indent is embedded in acoustic damping tuning part 3 and Air Filter 2 in inner groovy 43.Embodiment in figure, institute
Stating acoustic damping tuning part 3 is sheet body form, layered arrangement between acoustic damping tuning part 3 and Air Filter 2, acoustic damping tuning
Part 3 and the outer diameter of Air Filter 2 are in the same size.By being embedded assembling, realizes that plug connector 4 and preceding sound column 11 are coaxially connected, facilitate group
It closes and safeguards, have and change characteristic.And by being embedded assembling, realize that acoustic damping tuning part 3 and Air Filter 2 are mounted on grafting
In the inner groovy 43 of part 4, structure is simple, simple for production.In use, the sound that the sound outlet hole 111 of preceding sound column 11 is spread out of is by sound
It learns damping tuning part 3 to adjust, obtains ideal sound quality.Quantity, thickness, position etc. of the utility model to acoustic damping tuning part 3
With no restriction, as long as increasing by 3 tuning of acoustic damping tuning part on sound outlet hole 111 is the protection scope of the utility model,
Air Filter 2 has dust-proof, entrant sound effect, is not exclusively by design effectively also certainly to cooperate tuning.
Fig. 3, shown in 4, the utility model can also pore size inside the caulked section 41 by designing plug connector 4 adjust
Sound obtains perfect sound quality to cooperate acoustic damping tuning part 3.
Certainly, the figures above only depicts the preferred embodiments of the present invention, to the technology of the art
For personnel, pass through logical analysis, reasoning, or a limited experiment without departing from the utility model conception and scope
Can also to above-described embodiment number of improvements could be made and variation, such modifications and variations all should belong to the requires of the utility model protection
Range.
