Description

Technical Field

[0001] The utility model relates to the field of speaker detection, in particular to a speaker detection device. Background Art

[0002] Speakers are common sound-generating devices in our daily lives. Speakers, televisions, radios and other devices all need to use speakers, so the detection of speakers becomes particularly important.

[0003] At present, there are many sizes of speakers, and the conditions for speaker testing are also different. Common testing equipment can only test a single model or a single project. Not only is the test efficiency low, but the performance of the speaker cannot be fully tested.

[0004] After searching, it is found that a Chinese patent document discloses an audio speaker detection device [Application Number: 202320864609.8, Publication Number: CN219421040U]. This detection device is characterized in that it includes a detection table, a mounting frame and a detection head. Although the speaker detection device disclosed in the patent can perform detection, it can only detect one item and has requirements on the product size. It cannot achieve the effect of multi-size adaptation. At the same time, it has a speaker transport device, which increases the equipment cost. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 3 ,The utility model provides a technical solution: a speaker detection device includes a test platform, a tester and a plurality of test claws;

[0030] Specific:

[0031] The test platform includes an operating table 101, a support rod 102, a fixing plate 103, a stopper 104, a stopper rod 105, a bracket 106 and a bracket 2 107. The bracket is arranged at the back of the operating table 101. A track is provided at the front of the operating table 101. The track is provided from the top to the bottom and is located at the center of the operating table 101. The stopper 104 is slidably provided on the track. The stopper rod 105 is provided on the stopper 104. The operating table 101 is provided with a plurality of threaded holes. The threaded holes are evenly and equidistantly distributed at the top and bottom ends of the operating table 101. One end of the support rod 102 is installed in the threaded hole. The other end of the support rod 102 is detachably provided with a fixing plate 103.

[0032] The test claws described above all include a fixing platform 201, a positioning claw 202, a discharge claw 203, a piston 204 and a mounting platform 205. A strip hole is provided on the positioning claw 202. The positioning claw 202 is slidably arranged on the mounting platform 205. The fixing platform 201 is arranged on the mounting platform 205. The piston 204 is arranged on the fixing platform 201. The discharge claw 203 is arranged on the piston 204. The discharge end of the discharge claw 203 is opposite to the positioning end of the positioning claw 202. The fixing platform 201 is arranged on the operating platform 101.

[0033] The limiter 104, piston 204 and discharge claw 203 are electrically connected to the tester. The braking position of the limiter 104 is set according to the position where the test claw is placed. The limiter 104 is set at the top of the track by default. After the speaker is placed and the test begins, the limiter 104 will limit the speaker to the test position. At this time, the pin of the speaker is between the positioning claw 202 and the discharge claw 203. The piston 204 receives an electrical signal and pushes out the discharge claw 203, so that the positioning claw 202 and the discharge claw 203 clamp the speaker pin. The tester controls one side of the discharge claw 203 to discharge as the positive electrode and the other side of the discharge claw 203 as the negative electrode according to the test voltage and test duration required in the test task. After the test is completed, the piston 204 receives an electrical signal and pulls back the discharge claw 203. The limiter 104 limits the speaker to the next test position or moves to the bottom of the track. After the test is completed, the speaker is taken out and the limiter 104 is reset. After the speaker is placed, the next round of testing can be carried out.

[0034] Specifically, bracket 106 is arranged at the bottom of the operating table, and bracket 2 107 is arranged at the top of the operating table. After the brackets are assembled, the operating table 101 has a slope of 30° with the horizontal plane, so that the tested speaker can slide down along the fixed plate under the action of gravity, which solves the problem of needing to design speaker transportation equipment under horizontal conditions, which not only saves equipment costs, but also saves internal space of the equipment.

[0035] Specifically, the positioning claw 202 is detachably mounted on the mounting platform 205 by bolts. Depending on the size of the test horn, the positioning claw 202 can be moved forward and backward by loosening or tightening the bolts to adjust the position of the positioning claw 202, or the positioning claw 202 of a suitable size can be replaced to complete the test task.

[0036] Specifically, the limit rod 105 is detachable. According to the size of the test speaker, the limit rod 105 of the appropriate size can be replaced to complete the test task. At the same time, the limit rod 105 is used to support the speaker to prevent the speaker from rolling out of the test area.

[0037] Specifically, the test claws are set on the left and right sides of the track, the claw ends of the test claws are facing the track, the test claws are evenly arranged at equal distances, the size of the test claws is adjusted according to the size of the test horn, and the number of installed test claws can be set according to the requirements of the test task. A group of test claws undertakes a test task, which can reduce the variables in the test and thus improve the accuracy of the test results.
