Description

Technical Field

[0001] This utility model relates to the field of headphone speaker testing, and in particular to a headphone speaker sound quality testing device. Background Technology

[0002] The headphone speaker is the core component responsible for audio output in headphones. It consists of speaker units that convert electrical signals into sound waves, which generate sound by vibrating the diaphragm of the speaker unit. The quality of the speaker directly affects the sound quality, including the performance of high and low frequencies and the overall clarity of the sound. Different types of headphone speakers, such as dynamic, electrostatic, and planar magnetic speakers, have different sound characteristics and user experience. High-quality headphone speakers can usually provide richer, clearer, and more accurate audio performance.

[0003] Sound quality testing is an important means of evaluating the performance of audio equipment. It is mainly conducted through two methods: objective testing and subjective testing. Objective testing uses instruments to analyze parameters such as the frequency response, distortion rate, and signal-to-noise ratio of audio signals to ensure that the technical specifications of the equipment meet the standards. Subjective testing relies on the listener's perception to evaluate the clarity of sound quality, the performance of low, mid, and high frequencies, and the width of the soundstage. Sound quality testing helps consumers choose equipment that meets their needs and also provides data support for the optimization of audio equipment.

[0004] During headphone production, before assembly, the sound quality of each speaker on the headphones needs to be tested to check whether the sound quality of the current speaker meets the standard before assembly, so as to avoid increasing waste costs. However, traditional headphone speaker sound quality testing devices can only test one at a time, which is inefficient. Moreover, the test is simply placed on the test port, which cannot guarantee whether there is sound leakage, thus affecting the final test results. Therefore, a headphone speaker sound quality testing device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a headphone speaker sound quality testing device, which aims to improve the problems of traditional headphone speaker sound quality testing devices, which can only test one at a time, resulting in low efficiency, and the device simply places the speaker on the testing port during testing, which cannot guarantee whether there is sound leakage, thus affecting the final testing results.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a headphone speaker sound quality testing device, including a testing system, a transmission line plugged into the rear of the testing system, multiple fixing components installed inside the testing system, and an anti-drop component installed on the rear of the testing system;

[0007] The fixed assembly includes a worktable, the bottom of which is fixedly connected to the inside of the detection system.

Limit rods are slidably connected inside the sliders, and clamping blocks are fixedly connected to the top of the sliders. A rubber ring is fixedly connected to the top of the worktable.

[0008] As a further description of the above technical solution:

[0009] The anti-fall-off component includes a fixing ring, the front side of which is fixedly connected to the rear side of the detection system.

[0012] As a further description of the above technical solution:

[0013] The slider is externally slidably connected to the inside of the worktable, and the bottom of the clamping block is slidably connected to the top of the worktable.

[0014] As a further description of the above technical solution:

[0015] The rope is externally slidably connected inside the fixed ring, and the rope is internally fixedly connected to the outside of the slide plate.

[0016] As a further description of the above technical solution:

Limit rods 8 are slidably connected inside the sliders 7, and clamping blocks 9 are fixedly connected to the top of the sliders 7. A rubber ring 10 is fixedly connected to the top of the workbench 2. The workbench 2 is used to connect and protect internal parts and support the headphone speaker. The motor 3 is used to drive the worm gear 4 to rotate, and the worm gear 4 is used to drive the worm 5 to rotate. The meshing of the worm 5 and the worm gear 4 drives the turntable 6 to rotate. 5 is a hollow structure with an internal sound quality detection head. The turntable 6 drives the slider 7 to move, and the slider 7 drives the clamping block 9 to move synchronously. The limiting rod 8 limits the movement direction of the slider 7. The clamping block 9 clamps the headphone speaker. The inner side of the clamping block 9 is a slope, which can press downward while clamping the headphone. The rubber ring 10 is used to fit tightly with the headphone speaker to prevent sound leakage. The turntable 6 is externally rotatably connected to the inner wall of the worktable 2 to keep the turntable 6 stable. The limiting rod 8 is externally fixedly connected to the inside of the worktable 2 to keep the limiting rod 8 stable. The slider 7 is externally slidably connected to the inside of the worktable 2 to limit the movement direction of the slider 7.

[0036] Reference Figure 4 - Figure 6The anti-fall-off component includes a fixed ring 13, which is fixedly connected to the front of the detection system 1 at the rear. A rotating ring 14 is rotatably connected to the outside of the fixed ring 13. Four ropes 15 are fixedly connected to the inside of the rotating ring 14. Springs 16 are sleeved on the outside of the ropes 15. A slide plate 17 is fixedly connected to the inside of the springs 16. A connecting block 18 is fixedly connected to the inside of the slide plate 17. A locking block 11 is fixedly connected to the inside of the connecting block 18. The fixed ring 13 is used to connect and limit other parts. The rotating ring 14 wraps around the fixed ring 13 and is connected to the springs 16 for easy rotation. The ropes 15 are used to pull the slide plate 17 to move. The springs 16 are used to make the slide plate 17 automatically return to its original position. The connecting block 18 can only move in a specified direction under the limitation of the fixed ring 13 and will not move or wobble randomly. Its outer side is fixed. The slide plate 17 is there to prevent the connecting block 18 from falling off due to exceeding its range of movement. The connecting block 18 is used to drive the locking block 11 to move synchronously. The locking block 11 is used to clamp the transmission line 12 to prevent it from falling off due to pulling. The rope 15 is externally slidably connected to the inside of the fixing ring 13. The inside of the rope 15 is fixedly connected to the outside of the slide plate 17 so that when the rope 15 moves, it can pull the slide plate 17 to move synchronously. The spring 16 is externally fixedly connected to the inside of the fixing ring 13 to keep the spring 16 stable. The slide plate 17 is externally slidably connected to the inner wall of the fixing ring 13. The connecting block 18 is externally slidably connected to the inside of the fixing ring 13. The fixing ring 13 simultaneously restricts the movement direction of the slide plate 17 and the connecting block 18. The inside of the locking block 11 and the outside of the transmission line 12 are engaged to keep the transmission line 12 stable.

[0037] Working Principle: When using the detection system 1 to test the sound quality of the headphone speaker, first connect the detection system 1 to the display screen via the transmission line 12. By rotating the rotating ring 14, the rope 15 pulls the slide plate 17 to compress the spring 16, causing the connecting block 18 to retract into the fixed ring 13, thus unfolding the locking block 11. Next, insert the transmission line 12 into the back of the detection system 1 and release the rotating ring 14. At this time, the spring 16 will instantly push the slide plate 17, causing the connecting block 18 to reset, so that the locking block 11 is locked outside the transmission line 12, thereby preventing the transmission line 12 from falling off due to pulling. Then, control the cylinder to open the detection system 1, and place the headphone speaker on the rubber ring 10 of the workbench 2 in sequence. At this time, control the motor 3 to rotate, and the motor 3 drives the worm gear 4 to rotate. It engages with the worm gear 5, causing the turntable 6 to rotate. Under the limit of the limit rod 8, the slider 7 drives the clamping block 9 to move, clamping the headphone speaker. It cooperates with the inclined surface of the clamping block 9 and the rubber ring 10 to press the headphone onto the rubber ring 10 to prevent sound leakage. Then, the detection system 1 is turned off to isolate the internal and external sound. At this time, the detection system 1 can start the detection. The terminal on the detection system 1 contacts the contact point on the headphone speaker to make the speaker sound. The detection is carried out by the detection head. Finally, the detection data is transmitted to the display screen along the transmission line 12 for display, thus realizing the detection. This device can detect multiple headphone speakers at one time, effectively improving the detection efficiency. After the detection is completed, the motor 3 is reversed to make the clamping block 9 release the headphone speaker, saving time and effort.
