Below in conjunction with drawings and Examples the utility model is described further.Present embodiment is set forth with the test speaker (loud speaker) of bluetooth earphone and microphone (microphone) as an example.
To shown in Figure 7, a kind of audio test device that the utility model provides comprises such as Fig. 1:
Be located at the artificial ear 300 of artificial mouth 200 1 sides, be fixed on the described base plate 100;
Described positioning unit 500 comprises:
Described audio test device also comprises:
Artificial mouth bracing frame 210, described artificial mouth bracing frame 210 are fixed on the described base plate 100, described artificial mouth bracing frame 210 fixing described artificial mouths 200.Artificial mouth bracing frame 210 materials are aluminium alloy, the described artificial mouth 200 of fixed clamp.
Artificial ear supporting seat 310, described artificial ear supporting seat 310 are fixed on the described base plate 100, described artificial ear supporting seat 310 fixing described artificial ears 300.Described artificial ear supporting seat 310 is bakelite, fixedly the described artificial ear 300 of clamping.
When the test different product, in order to adapt to the size of different product, above-described artificial mouth bracing frame 210 and artificial ear supporting seat 310 be the relative sliding adjusting position point-blank, regulating the distance of artificial mouth 200 and bluetooth earphone microphone (microphone), and so that the center of artificial mouth 200 over against the center of microphone (microphone).
Concrete, described test bench 400 bottoms are provided with copper band 410, and described copper band 410 is enclosed within on the artificial ear 300, and test bench 400 can rotate within the specific limits.Also be provided with silicagel pad 420 on the test bench 400, the shape of this silicagel pad 420 can be designed to according to the shape of tested person product corresponding shape.Because silica gel is soft; so can protect the Surface Appearance of tested person not by the mill flower; after the tested person product being put on the silicagel pad 420 of respective shapes; copper band 410 is enclosed within on the artificial ear 300 in addition, so the sound that can basic guarantee artificial ear 300 can send at the space of relative closure build-in test bluetooth earphone speaker.
