[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.
[0031] Please refer to Figures 1 to 4 , a loudspeaker testing tool, comprising:
[0032] A baffle 1, wherein the baffle 1 is provided with a first positioning groove 11 for positioning the bottom of the speaker, a sound outlet 12 is provided on the bottom surface of the first positioning groove 11, and the baffle 1 is also provided with a plurality of air suction holes 13 for adsorbing the FPC, an air suction channel 14 connected to the air suction holes 13 is provided inside the baffle 1, and an air source port 15 connected to the air suction channel 14 is provided on the outer surface of the baffle 1;
[0033] A pressing plate 2, on which a conducting probe 4 for conducting the FPC is disposed, and a pressing block 21 for pressing the FPC is disposed on a side of the pressing plate 2 close to the baffle 1;
[0034] A quick toggle clamp 3 is installed on the baffle plate 1 , and is used to press the pressure plate 2 toward the sound outlet 12 so that the pressure plate 2 is fixed on the baffle plate 1 .
[0035] From the above description, it can be seen that the beneficial effect of the utility model is that the structure of the speaker test tool is simple and novel, and it can be modified on the basis of the existing speaker test tool, and it is easy to promote and apply. When using the speaker test tool to assist the speaker test, first dock the air source port 15 with the external suction pump, then place the speaker to be tested together with the FPC on the baffle 1, and let the suction generated by the suction hole 13 adsorb the FPC, then flatten the FPC on the baffle 1 to make the FPC flat, then cover the pressing plate 2 and fix the pressing plate 2 and the baffle 1 with the quick elbow clamp 3, at this time, the pressing block 21 on the pressing plate 2 will press the FPC tightly, and finally turn off the suction pump, and then perform the speaker test to avoid the suction pump affecting the test results of the speaker. The power connection point of the flattened FPC can be aligned with the conduction probe 4 on the pressing plate 2, so as to ensure that the conduction probe 4 can smoothly power on the FPC, thereby avoiding the phenomenon that the speaker fails to power on without sound, which is conducive to ensuring the smooth progress of the speaker listening test.
[0036] Furthermore, there are multiple pressing blocks 21.
[0037] As can be seen from the above description, providing a plurality of pressing blocks 21 can allow multiple areas of the FPC to be firmly pressed, thereby ensuring the flatness of the FPC during testing and ensuring that the speaker to be tested can be powered on smoothly.
[0038] Furthermore, the pressing block 21 and the air suction hole 13 are arranged in a staggered manner.
[0039] From the above description, it can be seen that the FPC area corresponding to the air intake hole 13 can become relatively flat under the adsorption effect of the air intake hole 13, and the pressing block 21 presses the area of the FPC that does not correspond to the air intake hole 13 to allow more areas of the FPC to remain flat, which is conducive to achieving the flatness of a larger area of the FPC with fewer air intake holes 13 / pressing blocks 21, thereby simplifying the structural design of the speaker testing tooling.
[0040] Furthermore, the number of the quick toggle clamps 3 is two, and the two quick toggle clamps 3 are arranged opposite to each other.
[0041] It can be seen from the above description that the two relatively arranged quick toggle clamps 3 can make the pressure on the pressure plate 2 more balanced, thereby improving the pressure effect of the pressure plate 2 on the speaker and the airtightness between the speaker to be tested and the baffle 1.
[0042] Furthermore, an air suction hole 13 is provided near the conduction probe 4 .
[0043] From the above description, it can be seen that the suction hole 13 arranged close to the conductive probe 4 will also be close to the power connection point of the FPC. The suction hole 13 is arranged close to the power connection point of the FPC, which can ensure the flatness of the power connection point of the FPC, thereby ensuring that the conductive probe 4 can smoothly contact and conduct with the power connection point of the FPC.
[0044] Furthermore, a pressing block 21 is disposed close to the conducting probe 4 .
[0045] From the above description, it can be seen that the pressing block 21 is arranged close to the conductive probe 4, which means that the pressing block 21 is close to the power contact point of the FPC, which is conducive to ensuring the flatness of the FPC power contact point, thereby ensuring that the conductive probe 4 can smoothly contact and conduct with the FPC power contact point.
[0046] Furthermore, a boss 22 for pressing the top of the speaker is provided on the bottom surface of the pressing plate 2 .
[0047] It can be seen from the above description that the arrangement of the protrusion 22 enables the pressing plate 2 to press tightly against the speaker to be tested.
[0048] Furthermore, the baffle plate 1 is provided with a second positioning groove 16 for positioning the pressing plate 2 , and the pressing plate 2 is provided with a positioning block 23 matched with the second positioning groove 16 .
[0049] It can be seen from the above description that the cooperation between the second positioning groove 16 and the positioning block 23 can enable the pressing plate 2 and the baffle plate 1 to be accurately positioned and assembled.
[0050] Furthermore, the air intake channel 14 is connected to the peripheral wall of the baffle plate 1 , and a sealing plug 5 is provided at the connection point between the air intake channel 14 and the peripheral wall; the air source port 15 is provided on the surface of the baffle plate 1 having the first positioning groove 11 .
[0051] It can be seen from the above description that the processing method of the air intake channel 14 is simple and efficient, which simplifies the structure of the baffle plate 1 and facilitates the processing and manufacturing of the baffle plate 1.
