The purpose of the present invention is to be achieved through the following technical solutions：
A kind of earphone test device and its method of testing for electroacoustical measurement, including machinery chassis, support frame,
Earphone built, artitificial ear and adapter fixture (or artitificial ear fixture), Mike's rack and artificial mouth,
Two positions of artitificial ear on structural vertical center into symmetrical expression step by step, and inclined angle is 16 °,
It is characterized in that：Two positions of artitificial ear are used to simulate the position of human ear, are more nearly actual application ring
Border, it is ensured that the accuracy of test.
Whole test device is put by mechanical pedestal, support beam, earphone built, artitificial ear fixture and Mike
Put frame composition.By adding artificial mouth, headset earpiece and Mike can be tested simultaneously；
The advantage of the invention is that：
1st, two artitificial ears of apparatus of the present invention are fixed in same support beam, it is ensured that stability；And
There is scale above support beam, be easy to be accurately positioned；
2nd, two inclined angles in artitificial ear fixed position of apparatus of the present invention are 16 °, can preferably be simulated
The physical location of human ear so that the result of measurement more meets practical application request；
3rd, test device simple structure of the present invention, with low cost, good operating stability；
4th, test device provided by the present invention have regulation easily, use the spies such as simple, strong antijamming capability
Point, can be used for electroacoustical measurement field；
Brief description of the drawings

Machine)；
Fig. 2 artitificial ears fixture (test In-Ear Headphones) structural representation；
In figure：
1st, machinery chassis 2, support beam 3, earphone built 4, artitificial ear and adapter fixture 5,
Mike's rack 6, artificial mouth 7, artitificial ear fixture
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples；
The present invention is provided to the earphone test device and its method of testing of electroacoustical measurement, methods described is：Swash
Encourage what source of sound earphone sent, by artitificial ear and adapter (being directed to wall-mounted earphone) or directly by people
After work ear (being directed to In-Ear Headphones) collection, the reception device (accompanying drawing is not provided) of rear end is transferred to, and pass
It is defeated to carry out data analysis, treatment to computer end and preserve；Meanwhile, by using artificial mouth 6, the excitation for sending
Source of sound, is received by the earphone Mike on Mike's rack 5, then by earphone cord, is transferred to electricity
Brain end carries out data analysis, treatment and preserves；
The specific annexation of described earphone test device is as follows：
Machinery chassis 1 are positioned on horizontal countertop, using 2 M6 bolts support beam 2 and machine
Tool chassis 1 is fixed, and support beam is used to place artitificial ear and adapter fixture 4 or artitificial ear fixture 7；
The earphone test built that will be assembled is inserted into the U-type groove at the top of support beam, and uses the spiral shell of M5
Silk is fixed；Two artitificial ears and adapter fixture 4 or artitificial ear fixture 7 are directly sleeved on by slide rail
Above support beam, and according to the scale in support, optimum position is moved precisely to, uses star-like handle
It is fixed, after fixing, two inclined angles of artitificial ear are 16 °, the position for simulating actual human ear
Put；Using artificial mouth key screw artificial mouth 6, the upper table of machinery chassis 1 is fixed on by the preformed hole of machinery chassis
Face；The preformed hole of horizontal support bar and artificial mouth common bed in Mike's rack and it is bolted to chassis
Above；
Embodiment：
The length of whole earphone test device is 226mm, width 210mm, and height 260mm, material is aluminium
