Description

Technical Field

[0001] This utility model belongs to the technical field of detection devices, and in particular relates to an automatic speaker detection device. Background Technology

[0002] Loudspeakers, as one of the most commonly used electroacoustic devices in daily life, have a wide range of applications. People are paying more and more attention to the sound quality of loudspeakers. Loudspeaker performance testing equipment is a very important performance testing device in loudspeaker production. In the past, loudspeaker performance testing required employees to manually connect plugs and power supplies to conduct the tests, which was not convenient. A search revealed that patent application number 201821525221.0 discloses an automatic loudspeaker performance testing device, including a workbench, contacts, and a loudspeaker placement platform mounted on the upper surface of the workbench. The upper surface of the workbench also has a display screen and a vertical support. A horizontal mounting plate is mounted on the upper end of the support, and a cylinder is set on the lower end of the mounting plate. An adapter plate is mounted on the end of the piston rod of the cylinder. A horizontal telescopic rod is set on the side of the adapter plate. A connecting block is set on the end of the telescopic rod away from the adapter plate. The connecting block has a downward-opening receiving groove. The contacts are hinged to the opening of the receiving groove through a rotating shaft. The contacts and the display screen are electrically connected.

[0003] However, in actual use, the applicant found that when testing the speaker through the contact, the person to be tested needs to place the speaker on the workbench. Since the workbench lacks a positioning structure for the speaker, in order for the contact to make good contact with the plug solder piece on the speaker, the person needs to manually move and adjust the position of the speaker, which makes it difficult to achieve accurate positioning of the speaker. Therefore, it is not convenient to operate. In view of this, we propose an automatic speaker testing device. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] An automatic loudspeaker testing device includes a testing platform 1. A top plate 3 is fixedly connected to the top of the testing platform 1 via a support column 2. A movable seat 9 is slidably connected to the bottom of the top plate 3. The movable seat 9 slides along a guide groove 31 opened at the bottom of the top plate 3. A screw 32 is rotatably connected to the inside of the top plate 3 via a bearing. One end of the screw 32 is coaxially connected to the output end of a motor 4 fixedly installed on the outer wall of one side of the top plate 3, and the other end of the screw 32 is threaded through the upper part of the movable seat 9. An electric push rod 91 is fixedly installed in the movable seat 9. A detection probe 10 is fixedly connected to the telescopic end of the electric push rod 91 via a connecting block 92. A positioning plate 7 is provided on the testing platform 1 below the detection probe 10. A loudspeaker placement slot 71 is opened on the top of the positioning plate 7. There are three loudspeaker placement slots 71 on the top of the positioning plate 7. The three loudspeaker placement slots 71 are different. Through the three loudspeaker placement slots 71, three loudspeakers can be tested. Different models of loudspeakers are positioned so that the test probe 10 can be smoothly inserted into the plug solder pad of the loudspeaker for testing. A support frame 13 is fixedly connected to one side of the test table 1. A display screen 5 and a controller 6 are fixedly installed on the top of the support frame 13. The controller 6 is electrically connected to an external power supply through wires. The motor 4, display screen 5, controller 6, electric push rod 91 and test probe 10 are electrically connected through wires. By placing the loudspeaker to be tested in the corresponding loudspeaker placement slot 71 according to its model, and driving the motor 4 through the controller 6 to move the test probe 10 to directly above the plug solder pad on the loudspeaker, and driving the electric push rod 91 to move the test probe 10 downward so that the test probe 10 can smoothly contact the plug solder pad, the loudspeaker can be automatically tested without the need for manual adjustment of the loudspeaker placement position, making the loudspeaker testing faster and more accurate.

[0022] The front of the testing table 1 has a storage slot 14 for storing positioning plates 7. Symmetrically arranged on both sides of the storage slot 14 are second limiting grooves 15. Several sets of second limiting grooves 15 are vertically spaced at equal intervals on the sidewalls of the storage slot 14. A positioning plate 7 is inserted into each set of second limiting grooves 15 in the storage slot 14. The speaker placement slots 71 on each positioning plate 7 are different. The top of the testing table 1 has an insertion slot 11. Symmetrically arranged on both sides of the insertion slot 11 are first limiting grooves 12. Positioning plates 7 are inserted into the insertion slot 11. Symmetrically arranged on both sides of the positioning plate 7 are limiting protrusions 72 that mate with the first limiting grooves 12 and the second limiting grooves 15. A handle 73 is fixedly installed on the front of the positioning plate 7. On the other side, a locking bolt 8 is threadedly connected. The thread helix angle on the locking bolt 8 is less than the equivalent friction angle, which enables the locking bolt 8 to achieve self-locking and prevent the locking bolt 8 from loosening. This prevents the positioning plate 7 from moving back and forth. One end of the locking bolt 8 inside the testing table 1 extends into the first limiting groove 12 and abuts against the positioning plate 7. The other end of the locking bolt 8 outside the testing table 1 is fitted with an adjusting plate 81. By setting multiple positioning plates 7 and making the speaker placement slots 71 on the top of the positioning plates 7 different, the positioning of multiple different models of speakers can be achieved by replacing the positioning plates 7 inserted in the insertion slot 11. This makes the device suitable for testing multiple different models of speakers.

[0023] Working principle: In use, the speaker to be tested is placed in the corresponding speaker placement slot 71, and the controller 6 drives the motor 4 to rotate, which in turn drives the screw 32 to rotate. The rotation of the screw 32 can drive the moving seat 9 to move along the guide slide 31, and move the detection probe 10 to directly above the plug solder piece on the speaker to be tested. At this time, the controller 6 can drive the electric push rod 91 to move the connecting block 92 and the detection probe 10 downward, so that the detection probe 10 can smoothly contact the plug solder piece, and the speaker can be automatically tested. The test data and results can be displayed on the display screen 5. By taking out the required positioning plate 7 from the storage plate slot 14 and inserting it into the insertion plate slot 11, the adjustment plate 81 is manually rotated clockwise to drive the clamping bolt 8 to rotate. The clamping bolt 8 clamps the positioning plate 7 inserted in the insertion plate slot 11, and the positioning plate 7 can be adjusted. Thus, the speaker placement slot 71 on the top of the positioning plate 7 can meet the placement and positioning of different models of speakers.
