It includes a fixed assembly 10, a swing simulation assembly 20, and a rotating assembly 30. The fixed assembly 10 includes a base plate 11, a channel steel 12 fixed to the upper end of the base plate 11, and two symmetrically distributed headphone fixtures 13 slidably connected to the channel steel 12.

The swing simulation assembly 20 includes a connecting plate 21 and two symmetrically distributed lifting drive modules 22 on the upper end of the connecting plate 21. The driving end of each lifting drive module 22 is hinged to the base plate 11. The lifting drive modules 22 drive the base plate 11 to rotate in a vertical plane. The rotating assembly 30 includes a rotating platform 31 fixed to the lower end of the connecting plate 21 to drive the connecting plate 21 to rotate in a horizontal plane.

[0030] It also includes a soundproof enclosure 40, with a speaker 41 located on the top inner side of the enclosure 40; a fixing component 10, a swing simulation component 20, and a rotating component 30 are located inside the soundproof enclosure 40; furthermore, a connecting bracket 42 is provided on the top inner side of the soundproof enclosure 40, and the speaker 41 is mounted on the lower end of the connecting bracket 42; sound-absorbing cotton 43 is also provided on the inner wall of the soundproof enclosure 40.

[0031] During the headphone simulation test, the headphones are placed in a simulated earmold; the headphones are activated, and the audio receiver 14 receives the audio signal from the headphones and converts it into an electrical signal through a conversion circuit to detect the headphone's output sound effects, etc. Two lifting drive modules 22 are included, and simultaneously...

Figure 2 The device rotates vertically around axis A, driving the simulated earmold to swing and mimic the swinging motion of the earphones. This simulates the earphones' fit and wearing stability. The simulation testing device is placed inside a soundproof enclosure 40 to isolate external noise, while the speaker 41 emits simulated ambient sound.
