[0002] like Figure 1 The image shows a superlinear loudspeaker, a type of loudspeaker that effectively reduces distortion. The unique feature of this loudspeaker is its ability to achieve a linear vibrational response in terms of kinematics and mechanics, while exhibiting a non-linear vibrational response in terms of signal reception. It possesses high dynamic range and affinity, making it suitable for high-fidelity audio and professional audio applications.

[0003] The ultra-linear loudspeaker uses dual coils to drive the diaphragm, reducing distortion as volume increases. This design changes the way traditional loudspeakers are stressed, requiring professional testing to verify its ability to maintain sound fidelity at high volumes. Currently, during sound testing, air leakage occurs at the vent hole of the ultra-linear loudspeaker's sound outlet, resulting in low accuracy in subsequent tests.

[0004] Therefore, it is desirable to provide an automatic detection device for superlinear loudspeakers that can solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic detection device for superlinear loudspeakers, which can quickly push the superlinear loudspeaker to be tested to a designated position and ensure that the edge of the sound outlet of the superlinear loudspeaker is in close contact with the air outlet hole to avoid air leakage and ensure the accuracy of subsequent testing.

[0012] The first cylinder is mounted on the horizontal plate, and the piston rod of the first cylinder is horizontally mounted and always perpendicular to the vertical plate;

[0013] The mounting base is fixed to the end of the piston rod of the first cylinder;

[0014] The upper surface of the mounting base has a contoured mounting groove that is adapted to the super-line loudspeaker to be tested.

[0015] The pressing device includes a second cylinder and a pressing block;

[0016] The second cylinder is installed on the upper part of the vertical plate, and the piston rod of the second cylinder is set vertically downward;

[0017] The lower pressure block is fixed to the end of the piston rod of the second cylinder and always remains horizontal;

[0018] The lower surface of the pressure block has a contoured protrusion that is adapted to the super-linear loudspeaker to be tested.

[0019] Preferably, the bottom of the horizontal plate has a triangular reinforcing plate, and the front end of the triangular reinforcing plate is fixed to the vertical plate.

[0020] Preferably, guide rails are provided on both sides of the first cylinder on the horizontal plate;

[0033] Example

[0034] This embodiment of an automatic detection device for superlinear loudspeakers includes a support device, a horizontal pushing device, and a pressing device.

[0035] like Figure 2 As shown, the support device includes a vertical plate 1 and a horizontal plate 2; the vertical plate 1 has an air outlet 3 at its center, and the edge of the air inlet end of the air outlet 3 has an elastic contoured frame 4, which is adapted to the sound outlet of the super-linear loudspeaker to be tested.

[0036] The horizontal plate 2 is fixed to the lower part of the vertical plate 1 and is horizontally arranged; the horizontal plate 2 is located directly below the air outlet 3.

[0037] In this embodiment, the bottom of the horizontal plate 2 has a triangular reinforcing plate 5, and the front end of the triangular reinforcing plate 5 is fixed to the vertical plate 1; this arrangement effectively ensures the stability of the connection between the horizontal plate 2 and the vertical plate 1.

[0038] like Figure 3 and Figure 4 As shown, the horizontal pushing device includes a first cylinder 6 and a mounting base 7; the first cylinder 6 is disposed on the horizontal plate 2, and the piston rod of the first cylinder 6 is horizontally disposed and always perpendicular to the vertical plate 1; the mounting base 7 is fixed to the end of the piston rod of the first cylinder 6; the upper surface of the mounting base 7 has a contour mounting groove 8, which is adapted to the super-line loudspeaker to be tested.

[0039] In this embodiment, as Figure 4 As shown, guide rails 9 are provided on both sides of the first cylinder 6 on the horizontal plate 2; sliders 10 are fixed at the bottom of the mounting base 7 at the positions corresponding to the guide rails 9, and the sliders 10 are slidably mounted on the corresponding guide rails 9; this arrangement effectively ensures the linearity of the movement direction of the mounting base 7.

[0040] In this embodiment, as Figure 2 As shown, a stop block 11 is fixed at the front end of the horizontal plate 2. When the first cylinder 6 drives the mounting base 7 to move forward until it is blocked by the stop block 11, the sound hole of the super-wire speaker placed on the mounting base 7 is just in close contact with the elastic contoured frame 4 on the air outlet 3, which effectively ensures the subsequent detection accuracy and avoids the super-wire speaker from being crushed due to excessive forward movement.

[0041] like Figure 5 As shown, the pressing device includes a second cylinder 12 and a pressing block 13; the second cylinder 12 is installed on the upper part of the vertical plate 1, and the piston rod of the second cylinder 12 is set vertically downward; the pressing block 13 is fixed to the end of the piston rod of the second cylinder 12 and always remains horizontal; the lower surface of the pressing block 13 has a contoured protrusion (not shown in the drawing), and the contoured protrusion is adapted to the super-line loudspeaker to be tested.

[0042] In this embodiment, the second cylinder 12 is a guide rod cylinder, which ensures the linearity of the movement direction of the lower pressure block 13.

[0043] In this embodiment, the mounting base 7 is also provided with a power socket 14, which facilitates connecting the plug on the super-wire speaker to be tested to the power supply for testing.

[0044] When testing the sound output of the super-wire loudspeaker, first place it in the contour mounting groove 8 of the mounting base 7, start the first cylinder 6, the first cylinder 6 drives the mounting base 7 to move forward until the edge of the sound outlet 15 on the super-wire loudspeaker is in close contact with the elastic contour frame 4 on the air outlet 3, then start the second cylinder 12, the second cylinder 12 drives the lower pressure plate 13 to move downward until the super-wire loudspeaker is pressed tightly, connect the power supply to the super-wire loudspeaker, and then test its sound output.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
