Abstract
The utility model discloses an audio testing frock of headphone. Headphone audio testing frock includes the left and right earpiece of structure symmetry, and every earpiece all includes coupling frock and artificial ear, is provided with in the wherein coupling frock to be used for holding the coupled cavity of earphone ear muff of awaiting measuring, the artificial ear is connected with coupling frock interference fit, and emulation preauricular chamber annular edge is a plane with the laminating plane of earphone ear muff with the coupling frock of awaiting measuring. The utility model has the advantages of simple structure, the extrusion deformation of earphone ear muff pusula cotton in test procedure is effectively avoided to locating ear machine ear muff that can be fine to the difference that can eliminate earpiece about test fixture adds the influence of the dynamic balance nature of holding to the earphone top news, and the otherness of putting the test result that causes is got repeatedly in control, reduces the retest, improves the direct rate of test and the efficiency of earphone, and being convenient for get and putting, when testing the headphone, clamping -force through earphone self fixes earmuff about the earphone, reflects truly that the earphone wears the situation at people's ear.
Description
Technical field
The utility model is related to audio-frequency test frock, particularly to a kind of audio-frequency test frock of headphone.
Background technology
With scientific and technological progress, the popularization of electronic product, the requirement more and more higher to product for the consumer.Particularly people couple
Quality requirements also more and more higher in headphone product.Do not require nothing more than it to have as high, medium and low well arranged and theater
Curl up surrounding tonequality performance, also require that product has beautiful outward appearance and good wearing comfort, it is when long simultaneously
Between use in the case of, also will not produce sense of fatigue.
In order to meet the requirement to comfortableness for the consumer, the earmuff of headphone can add a circle thick for 6 millimeters with
On foam as interior village, additional earmuff being made by comfortable cloth or moccasin matter, Protein filament skin etc..Such earmuff
Be designed to so that earmuff is fitted well with human ear, it is to avoid human ear and the directly contact of Headphone structure part, carry to consumer
Comfortable wears experience.
But the requirement of headset audio quality is very high, especially about earphone loudspeaker frequency response performance uniformity and
Balance is extremely important, and when earphone is tested, the unreasonable of earphone test fixture design can cause foam in headset ear shell
Crimp, it is impossible to carry out good positioning to earphone, causes sound to reveal, and the difference of left and right test fixture also results in earphone top news
The imbalance of blessing power is it is difficult to eliminate the impact that the otherness that earphone picks and places repeatedly is tested to earpiece audio, thus causing earphone
A large amount of repetition measurements and erroneous judgement.
The audio-frequency test frock of current headphone is in order to carry out good positioning to earphone, it is to avoid repeatedly wears and draws
The otherness rising, does the locating dowel of several and earmuff equal height in earmuff surrounding.Although such Fixture Design has well
Positioning action, but very poor to the fault-tolerance of product to be measured, easily cause the crimp of foam in earmuff, impact earphone is beautiful
See；It is likely to cause sound to reveal, both of these case all can cause the unstable of test result, cause a large amount of repetition measurements and the mistake of earphone
Sentence, first-pass yield and efficiency that impact earphone is tested.
Content of the invention
In view of the audio-frequency test frock of headphone can not be prevented effectively from squeezing of foam in headset ear shell in prior art
