Description

Technical Field

[0001] This utility model belongs to the field of acoustic testing technology, specifically relating to a universal headphone audio testing fixture. Background Technology

[0002] Currently, audio testing fixtures for headphones generally lack versatility. A single fixture is often designed for a specific product or product series. When the product line is updated or a new acoustic product is launched, the old fixture is likely to become unusable. For example, if a brand upgrades the size and structure of its headphones, the existing testing fixture cannot accurately hold the new product. The fixture must be redesigned and manufactured, resulting in a significant increase in testing costs, a longer development cycle, and hindering rapid response to market changes.

[0003] Furthermore, some acoustic testing fixtures perform poorly in terms of accuracy and stability. During prolonged use, key components of the fixture may wear down, causing deviations in the sound acquisition position and ultimately affecting the accuracy of the test data. Moreover, some fixtures may undergo slight structural deformations under complex environmental conditions, such as changes in temperature and humidity, further reducing the stability of the test and making it difficult to meet the requirements for high-precision acoustic performance testing. Summary of the Invention

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0055] Example 1:

[0056] Please see Figures 1-3 This embodiment provides a universal headphone audio testing fixture, including a support base 100 for supporting and fixing various components and facilitating the movement of the testing fixture; two support components 200 for supporting the acoustic simulation components 300, which are positioned opposite each other on the support base 100 to accommodate the relative arrangement of the left and right earpieces of the headphone; two acoustic simulation components 300 for simulating the wearing of the test object (headphones) by a human ear, which are respectively positioned on the two support components 200 for wearing the left and right earpieces of the headphone; two pushing components 400 for pushing the two test objects to adhere to the acoustic simulation components 300; and a simulated mouth 500 located between the two acoustic simulation components 300 for simulating external sounds.

[0057] The support component 200 includes a support member 210 and an adsorption member 220 disposed on the support member 210. The adsorption member 220 is used to hold the acoustic simulation component 300 so as to facilitate the quick disassembly and installation of the acoustic simulation component 300.

[0058] Specifically, the adsorption component 220 is connected to the vacuum generator and can generate a vacuum adsorption effect under the action of the vacuum generator to hold the acoustic simulation component 300, or release gas under the action of the vacuum generator to quickly remove the acoustic simulation component 300. That is, in the audio testing of headphones, the acoustic simulation component 300 on the test fixture needs to be adapted to the shape and structure of the headphones. When a new product is launched on the production line, only the acoustic simulation component 300 needs to be replaced. However, traditional test fixtures are often designed for a certain product or a certain series of products and cannot be adapted to new products with different shapes and structures, resulting in a waste of resources. In this embodiment, the acoustic simulation component 300 adapted to the headphones is designed to be detachable and installable. When replacing a new product, only the acoustic simulation component 300 needs to be replaced, so that the main body of the fixture can still be used and resources can be reused.

[0059] The acoustic simulation component 300 is detachable and can be installed using a vacuum adsorption method. Under the action of a vacuum generator, the adsorption component 220 releases gas, allowing the operator to quickly remove the acoustic simulation component 300 for replacement. During installation, after adjusting the position of the acoustic simulation component 300 relative to the adsorption component 220, the adsorption component 220 generates a vacuum adsorption effect under the action of the vacuum generator, thus holding the acoustic simulation component 300 in place.

[0060] This embodiment provides a universal headphone audio testing fixture for audio testing of headphones. The acoustic simulation component 300 and the support component 200 are fixed together by adsorption. The acoustic simulation component 300 can be disassembled and replaced at any time according to the production line change requirements, so that the main body can be reused, effectively improving the versatility of the testing fixture and avoiding resource waste. By pushing the component 400 to push the test object, i.e., the headphone under test, to adhere to the acoustic simulation component 300, the positional stability of the headphone under test and the stability of the testing process are ensured, effectively improving the test effect and test accuracy.

[0061] In some embodiments, the pushing component 400 includes a translational drive 410 and a pushing block 420 connected to the driving end of the translational drive 410; the translational drive 410 drives the pushing block 420 to push the object under test to adhere to the acoustic simulation component 300, thereby ensuring the positional stability of the object under test and the stability of the testing process.

[0062] As is known, the test object is a pair of headphones. After the left and right earpieces of the headphones are worn and installed in the positions corresponding to the two acoustic simulation components 300, in order to ensure that the positions of the left and right earpieces do not change during the test, the translation drive 410 drives the push block 420 to move toward the acoustic simulation component 300, so that the left and right earpieces are tightly attached to the acoustic simulation component 300.

[0063] Among them, the side of the push block 420 facing the object to be tested is connected to a buffer for flexible contact. The flexible contact method can avoid damage to the surface of the object to be tested and improve the quality.

[0064] To prevent damage to the headphones from hard contact between the push block 420 and the headphones, a buffer is connected to the side of the push block 420 facing the headphones. The buffer can be made of materials such as foam or silicone that can make flexible contact with the headphones. Specifically, the buffer can be attached to the push block 420 or embedded in the push block 420 to ensure the connection stability of the buffer.

[0065] This embodiment provides a universal headphone audio testing fixture, which can improve the versatility of acoustic testing for headphone, as well as improve the testing effect and accuracy.

[0066] Example 2:

[0067] This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-3 Based on the above Figure 4 and Figure 5 .

[0068] In this embodiment, the universal headphone audio test fixture also includes a first adjustment component 600, which is disposed on the support base 100. The simulated mouth 500 is connected to the first adjustment component 600. The first adjustment component 600 is used to adjust the position of the simulated mouth 500 to ensure that the position of the simulated mouth 500 meets the test requirements and improves the test accuracy.

[0069] Specifically, the first adjustment component 600 includes a first adjustment block 610, a second adjustment block 620, and a third adjustment block 630 connected in sequence. The first adjustment block 610 is disposed on the support base 100. A first sliding groove 110 is formed on the support base 100 along the X direction. The first adjustment block 610 can slide along the first sliding groove 110 to adjust its position. For example, after adjusting the position of the first adjustment block 610 relative to the first sliding groove 110, the position of the first adjustment block 610 is locked by a locking member, etc. Similarly, a second sliding groove 611 is formed on the first adjustment block 610 along the Y direction. The second adjustment block 620 can slide along the second sliding groove 611 to adjust its position. A third sliding groove 621 is formed on the second adjustment block 620 along the Z direction. The third adjustment block 630 can slide along the third sliding groove 621 to adjust its position. The simulation nozzle 500 is connected to the third adjustment block 630.

[0070] By adjusting the positions of the first adjusting block 610, the second adjusting block 620, and the third adjusting block 630, the position of the simulated mouth 500 can be adjusted in the X, Y, and Z directions, so that the position of the simulated mouth 500 can be adapted to the testing requirements of the headphones, thereby improving the accuracy of the test.

[0071] In some embodiments, the first adjustment component 600 further includes a first rotating seat 640 disposed on the third adjustment block 630, and the first rotating seat 640 and the third adjustment block 630 are rotatably connected; the simulated nozzle 500 is connected to the first rotating seat 640, and the position of the simulated nozzle 500 is rotated and adjusted to ensure that the position of the simulated nozzle 500 meets the test requirements and improves the test accuracy.

[0072] Specifically, the first rotating seat 640 can rotate 360° relative to the third adjusting block 630. To facilitate recording the position adjustment of the simulated mouth 500, the starting scale line can be marked on the outer circumference of the first rotating seat 640, and the rotation angle can be marked on the third adjusting block 630 along the rotation path of the first rotating seat 640, so that the operator can quickly confirm whether the position of the simulated mouth 500 meets the test requirements during each test.

[0073] Example 3:

[0074] This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-5 Based on the above Figure 6 and Figure 7 .

[0075] In this embodiment, the universal headphone audio test fixture further includes a second adjustment component 700 and a support rod 800 for supporting the microphone. The support rod 800 is connected to the second adjustment component 700, which is disposed on the support base 100 and adjacent to the simulated mouth 500. The second adjustment component 700 is used to adjust the position of the support rod 800, that is, to adjust the position of the microphone, ensuring that the position of the microphone meets the test requirements and improving the test accuracy.

[0076] Specifically, the top of the support rod 800 is formed with a contour groove 810 for accommodating the microphone. The internal structure of the contour groove 810 matches the shape of the microphone to ensure the stability of the microphone support.

[0077] In some embodiments, the second adjustment assembly 700 includes a fourth adjustment block 710, a fifth adjustment block 720, and a sixth adjustment block 730 connected in sequence. The fourth adjustment block 710 is disposed on the support base 100 and its position is adjusted relative to the support base 100 along the X direction. For example, an adjustment groove is provided on the support base 100. After the position of the fourth adjustment block 710 relative to the adjustment groove is adjusted, the position of the fourth adjustment block 710 is locked by a locking member or the like. Similarly, the fifth adjustment block 720 can be adjusted relative to the fourth adjustment block 710 along the Y direction, and the support rod 800 can be adjusted relative to the sixth adjustment block 730 along the Z direction, thereby realizing the adjustment of the microphone's position in different directions.

[0078] Furthermore, the second adjustment assembly 700 also includes a second rotating seat 740 disposed on the fifth adjustment block 720, and the second rotating seat 740 and the fifth adjustment block 720 are rotatably connected; the sixth adjustment block 730 is connected to the second rotating seat 740 to rotate and adjust the position of the microphone to ensure that the position of the microphone meets the test requirements and improves the test accuracy.

[0079] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
