Description
Technical field
The present invention relates to audio-frequency test frock, particularly to the audio-frequency test frock of a kind of headband receiver.
Background technology
Along with the progress of science and technology, popularizing of electronic product, consumer is more and more higher to the requirement of product.Particularly people couple
More and more higher in the quality requirements of headband receiver 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 simultaneously, it is when long
Between use in the case of, also will not produce feeling of fatigue.
In order to meet consumer's requirement to comfortableness, the earmuff of headband receiver can add a circle thickness be 6 millimeters with
On foam as interior village, the additional earmuff etc. being made by comfortable cloth or moccasin matter, Protein filament skin.This type of earmuff
Be designed to make earmuff fit well with human ear, it is to avoid human ear directly contact with Headphone structure part, to consumer's band
Comfortable wears experience.
But the requirement of headset audio quality is the highest, especially the frequency response of earphone left and right loudspeaker performance concordance and
Balancing extremely important, when earphone is tested, the unreasonable meeting of earphone test fixture design causes foam in headset ear shell
Crimp, it is impossible to earphone is carried out good location, causes sound to reveal, and the difference of left and right test fixture also results in earphone top news
Add the imbalance of holding force, it is difficult to the impact that earpiece audio is tested by the diversity that elimination earphone picks and places repeatedly, thus cause earphone
A large amount of repetition measurements and erroneous judgement.
The audio-frequency test frock of current headband receiver is in order to carry out good location to earphone, it is to avoid repeatedly wears and draws
The diversity risen, does the locating dowel of several and earmuff equal height in earmuff surrounding.Although this type of 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, affect earphone beautiful
See；Being likely to cause sound to reveal, both of these case all can cause the instability of test result, causes a large amount of repetition measurements and the mistake of earphone
Sentence, affect first-pass yield and the efficiency of earphone test.
Summary of the invention
In view of in prior art, the audio-frequency test frock of headband receiver can not be prevented effectively from squeezing of foam in headset ear shell
Compressive strain, can not carry out good location in test process, and be difficult to ensure that the test that earphone picks and places repeatedly headset ear shell
The conforming problem of result, it is proposed that the audio-frequency test frock of a kind of headband receiver of the present invention, in order to solve or at least
Partly solve the problems referred to above.
According to an aspect of the invention, it is provided the audio-frequency test frock of a kind of headband receiver, described audio-frequency test
