[0002] With the popularity of smart phones and mobile devices, the demand for speakers is increasing. A device will be equipped with one or more speakers. Due to space limitations, some speakers will use longer FPCs. However, during the acoustic test, since the FPC is long and soft, it is easy for the FPC to bend and warp during the test, resulting in inaccurate connection points of the FPC. The conductive probe on the test tooling cannot contact the connection points of the FPC, resulting in the speaker failing to power on and the speaker not making any sound. Utility Model Content

[0025] 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.

[0026] Please refer to Figures 1 to 3 , a loudspeaker testing tool, comprising:

[0027] A baffle 1, wherein the baffle 1 is provided with a first positioning groove 11 for positioning the bottom of the speaker, and the bottom surface of the first positioning groove 11 is provided with a sound outlet, and the baffle 1 is also provided with a plurality of groups of limiting structures 13 for limiting the FPC, each group of the limiting structures 13 includes two limiting blocks 131 arranged opposite to each other, and a through groove 132 for the FPC to pass through is formed between the two limiting blocks 131 arranged opposite to each other;

[0028] 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;

[0029] 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 so that the pressure plate 2 is fixed on the baffle plate 1 .

[0030] From the above description, it can be seen that the beneficial effects of the utility model are: the structure of the speaker test fixture is simple and novel. When using the speaker test fixture to assist the speaker test, the speaker to be tested is placed on the baffle 1 together with the FPC, wherein a part of the FPC area is trapped in the limiting structure 13, and then the FPC is flattened on the baffle 1 to make the FPC flat, and then the pressing plate 2 is covered and the pressing plate 2 and the baffle 1 are fixed 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 the speaker test is performed. The power connection point of the flattened FPC can be aligned with the conductive probe 4 on the pressing plate 2, thereby ensuring that the conductive probe 4 can smoothly power on the speaker, thereby avoiding the phenomenon that the speaker fails to power on and does not make a sound, which is conducive to ensuring the smooth progress of the speaker listening test.

[0031] Furthermore, there are multiple pressing blocks 21 on the pressing plate 2.

[0032] 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.

[0033] Furthermore, the pressing block 21 and the limiting structure 13 are arranged in a staggered manner.

[0034] From the above description, it can be seen that the offset pressure blocks 21 and the limiting structures 13 can keep more areas of the FPC flat, which is conducive to achieving the flatness of a larger area of ​​the FPC with fewer limiting structures 13 / pressure blocks 21, simplifying the structural design of the speaker test tooling, and reducing the processing accuracy requirements of the speaker test tooling.

[0035] Furthermore, the number of the quick toggle clamps 3 is two, and the two quick toggle clamps 3 are arranged opposite to each other.

[0036] 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.

[0037] Furthermore, a group of the limiting structures 13 is arranged close to the conducting probes 4 .

[0038] From the above description, it can be seen that the limiting structure 13 set close to the conductive probe 4 will also be close to the power connection point of the FPC. The setting of the limiting structure 13 close to the power connection point of the FPC 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.

[0039] Furthermore, a pressing block 21 is disposed close to the conducting probe 4 .

[0040] 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.

[0041] Furthermore, a protrusion for pressing the top of the speaker is provided on the bottom surface of the pressing plate 2 .

[0042] It can be seen from the above description that the arrangement of the protrusions enables the pressing plate 2 to press tightly against the speaker to be tested.

[0043] Furthermore, the baffle plate 1 is provided with a second positioning groove 14 for positioning the pressing plate 2 , and the pressing plate 2 is provided with a positioning block 23 matched with the second positioning groove 14 .

[0044] It can be seen from the above description that the cooperation between the second positioning groove 14 and the positioning block 23 can enable the pressing plate 2 and the baffle plate 1 to be accurately positioned and assembled.
