Description

Technical Field

[0001] This utility model relates to the field of sound testing technology in loudspeaker production, specifically a sound testing device for loudspeaker production. Background Technology

[0002] As audio output devices, loudspeakers are widely used in audio systems, car audio systems, multimedia equipment, and other fields. Their sound quality directly affects the user's listening experience. Therefore, sound testing is a crucial step in ensuring product quality during loudspeaker production. Sound testing allows for the timely detection of potential defects during manufacturing, such as faulty voice coils, damaged diaphragms, and magnetic circuit malfunctions. This prevents substandard products from entering the market, protecting the company's reputation and consumer rights.

[0003] Traditional speaker testing devices currently on the market have significant limitations. These devices have a relatively simple functional architecture, and due to limitations in their mechanical structure and sensing systems, they can only perform acoustic tests at a single fixed distance. They cannot simulate the sound propagation characteristics at different distances. The fixing components in the devices use standardized clamping structures, which are only compatible with specific speaker models and cannot flexibly accommodate speaker types of different sizes and shapes. When facing diverse market demands, the devices lack versatility, increasing equipment procurement costs for companies and significantly reducing the efficiency of sound testing.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figures 1 to 4This utility model discloses a sound testing device for loudspeaker production, which includes a main body 1. An observation window 2 is fixedly installed on the outer wall of the main body 1. A door is hinged to the main body 1, and a handle 4 is fixedly connected to the door. A shock absorber 3 is fixedly installed at the bottom of the main body 1. An upper plate 7 is fixedly connected to the upper surface of the main body 1. A moving mechanism 5 is fixedly connected to the lower surface of the upper plate 7. A clamping mechanism 6 is fixedly connected below the moving mechanism 5. The moving mechanism 5 includes a first motor 501, a first lead screw 502, a fixed block 503, a guide rod 504, a moving block 505, a second lead screw 506, a second motor 507, and a microphone 508.

[0023] The upper surface of the first motor 501 is fixedly connected to the lower surface of the upper plate 7. The output end of the shaft of the first motor 501 is fixedly connected to the first lead screw 502. The two ends of the first lead screw 502 are fixedly connected to the fixing blocks 503. The two ends of the inner side of the fixing blocks 503 are fixedly connected to the guide rods 504. The sliders are fixedly installed on the first lead screw 502 and the guide rods 504. The moving block 505 is fixedly connected to the slider. The moving block 505 is sleeved on the second lead screw 506. The end of the second lead screw 506 is fixedly installed to the second motor 507. The microphone 508 is fixedly installed on the moving block 505.

[0024] The clamping mechanism 6 includes a cylinder 601, a first connecting block 602, a rack 603, a rubber chuck 604, a gear 605, a limiting slide groove 606, and a second connecting block 607. The cylinder 601 is fixedly connected to the bottom inside the main body 1. The first connecting block 602 is fixedly connected to the end of the telescopic rod of the cylinder 601. The rack 603 is fixedly connected to one side of the first connecting block 602. The second connecting block 607 is fixedly connected to the end of the rack 603. The rubber chuck 604 is fixedly connected to the upper surface of the second connecting block 607. The lower part of the rubber chuck 604 is slidably connected in the limiting slide groove 606. The gear 605 is meshed with the teeth on one side of the rack 603.

[0025] Working principle: An external air source starts cylinder 601, and the first connecting block 602 at the extension rod end of cylinder 601 drives rack 603 to move. One side of rack 603's teeth mesh with gear 605. When rack 603 moves, gear 605 rotates, thus driving rack 603 on the other side to move. Shock absorber 3 reduces the impact of vibration on the overall structure and internal components of the device. Observation window 2 allows operators to observe the internal workings of the main body 1 in real time and promptly detect abnormalities. After the external power source starts the first motor 501, it drives the first lead screw 502 to rotate. Since guide rods 504 are fixed at both ends of the inner side of the fixed block 503, and sliders fixedly connected to the moving block 505 are installed on the first lead screw 502 and the guide rods 504, the rotation of the first lead screw 502 will cause the moving block 505 to move linearly along the guide rods 504, thereby realizing the movement in the X-axis direction; the external power supply starts the second motor 507, the second motor 507 drives the second lead screw 506 to rotate, and the moving block 505 is sleeved on the second lead screw 506. Therefore, the rotation of the second lead screw 506 will drive the moving block 505 to move in the Y-axis direction. The microphone 508 installed on the moving block 505 can collect sound information during the operation of the device for observing the working status of the device.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
