Abstract
The utility model discloses a kind of totally-enclosed acoustic air-flow lateral leakage protection devices, including main body and it is set to the port of lower body, the upper end of main body is provided with convex block, U-shaped port is provided on convex block, the upper surface of main body is provided with the earphone bore of indent, the lower end of earphone bore is communicated with through-hole, the lower end of through-hole is connected to the port, by the way that the tail end of earphone to be detected to be fixed on to the U-shaped port on convex block, it will test earphone head end insertion earphone bore simultaneously, the characteristics of due to curved surface flexible resilient material, earphone can be made to form close-connected state in earphone bore, it solves irregular, abnormity, curved surface, arcuate shape auricular concha frequency sound test instability problem, guarantee the air-tightness of each section, anti- leak-stopping sound.
Description
Technical field
The utility model relates to shell for earphone frequency sound test technical field, specially a kind of totally-enclosed acoustic air-flow lateral leakage protection
Device.
Background technique
In earphone production process, for the psycho-acoustical quality for guaranteeing earphone, it usually needs surveyed to the response frequency of earphone
Examination.Test probe impedance and leakproofness by using manual operation in existing, because earphone irregular shape with the contract of die holder
It is right bad, lead to the case where leaking sound, often will cause the accuracy for being mixed into external noise and response test in the frequency of earphone,
So that the problem of test effect inaccurately causes the quality of production unstable and quality decline.
Utility model content
The purpose of this utility model is to provide a kind of totally-enclosed acoustic air-flow lateral leakage protection devices, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions: a kind of totally-enclosed acoustic air-flow lateral leakage protection dress
It sets, including main body and is set to the port of lower body, the upper end of the main body is provided with convex block, is provided with U on the convex block
Type port, the upper surface of the main body are provided with the earphone bore of indent, and the lower end of the earphone bore is communicated with through-hole, described
The lower end of through-hole is connected to the port.
Preferably, the main body is made of silica gel material and other flexible resilient materials.
Preferably, the earphone bore is curved-surface structure.
Compared with prior art, the utility model has the beneficial effects that a kind of totally-enclosed acoustic air-flow lateral leakage protection device, leads to
It crosses and the tail end of earphone to be detected is fixed on the U-shaped port on convex block, while will test earphone head end insertion earphone bore, due to
The characteristics of curved surface flexible resilient material, can make earphone form close-connected state in earphone bore, solve it is irregular,
Abnormity, curved surface, arcuate shape auricular concha frequency sound test instability problem, guarantee the air-tightness of each section, anti-leak-stopping sound.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model；
Fig. 2 is the top view of the utility model；
Fig. 3 is cut away view at the A-A in attached drawing Fig. 2.
Figure label are as follows: 1- main body, the port 2-, 3- convex block, 4-U type port, 5- earphone bore, 6- through-hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of totally-enclosed acoustic air-flow lateral leakage protection device,
Including main body 1 and it is set to the port 2 of 1 lower end of main body, the upper end of main body is provided with convex block 3, U-shaped port is provided on convex block 3
4, the upper surface of main body 1 is provided with the earphone bore 5 of indent, and the lower end of earphone bore 5 is communicated with through-hole 6, and the lower end of through-hole 6 connects
Go side mouthful 2.
Specifically, main body 1 is made of silica gel material and other flexible resilient materials.
Specifically, earphone bore 5 is curved-surface structure.
Working principle: in use, by the way that the tail end of earphone to be detected is fixed on the U-shaped port on convex block, while will inspection
It surveys earphone head end and is inserted into earphone bore, so that earphone forms close-connected state in earphone bore, tester is sharp at this time
Monitor frequency response with frequency response detection device, distinguish it is qualified with it is unqualified, after the completion of test, taking-up earphone can carry out next earphone
Test.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
