Description

Technical Field

[0001] The utility model relates to the technical field of earphone performance testing, in particular to a testing device for simulating human walking to verify a pedometer function of an earphone. Background Art

[0002] In the prior art, in order to be closer to the user's life, in addition to conventional functions such as calling and music playing, earphone products also have a pedometer function, which can record the number of steps the user walks or runs while wearing the earphones. Specifically, the earphones use a built-in 6-axis sensor (G-Senseor) to detect the displacement and angle changes in three directions of the XYZ three-dimensional space, and combine the corresponding pedometer algorithm to achieve the pedometer function. When the user walks with the earphones, the movement of the head will drive the movement of the earphones, and the sensors inside the earphones can sense this movement and record it. By analyzing these motion data, the earphones can calculate how many steps the user has walked. Advanced earphone pedometers may also combine other sensors, such as accelerometers and gyroscopes, to more accurately measure the user's movement and steps. These data can also be used to calculate information such as the user's distance, speed, and calories consumed.

[0003] At present, headphones with pedometer function need to undergo performance testing before leaving the factory. The specific process of the pedometer function test is: a real person wears the headphones and walks or runs for a period of time, and the number of steps taken by the real person is recorded and then compared with the number of steps displayed by the headphones to determine whether the pedometer function of the headphones is accurate. The above testing process is complicated, time-consuming and labor-intensive, and the testing efficiency is very low, which cannot meet the testing needs of large quantities of headphones.

[0004] Therefore, finding a technical solution that can solve the above technical problems has become an important topic studied by technical personnel in this field. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model discloses a testing device for simulating human walking to verify the pedometer function of an earphone, which is used to solve the technical problem that the pedometer function of an existing earphone needs to be simulated tested by a real person, resulting in a complicated testing process, which is time-consuming and labor-intensive.

[0026] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 , the embodiment of the utility model includes a test device for simulating human walking to verify the pedometer function of headphones, including a test bench 1, a driving member 5, a reciprocating transmission component and a simulated human ear component for wearing headphones;

[0028] The driving member 5 is installed on the test bench 1 and connected to the reciprocating transmission assembly. The simulated human ear assembly is connected to the reciprocating transmission assembly. The driving member 5 drives the simulated human ear assembly to reciprocate up and down in the vertical direction through the reciprocating transmission assembly.

[0029] During the test process of the test equipment of this embodiment, the earphones are worn on the simulated human ear component, and the reciprocating transmission component is driven by the driving member 5 to drive the simulated human ear component to do up and down reciprocating motion, simulating the movement posture of a person wearing earphones when walking or running, so as to judge whether the earphone pedometer function is accurate by comparing the up and down reciprocating motion times of the simulated human ear component with the step counting times of the earphone, thereby effectively improving the test efficiency and eliminating the need for real people to participate in the test, saving time and effort.

[0030] Furthermore, the driving member 5 in this embodiment is preferably a servo motor.

[0031] Furthermore, the reciprocating transmission assembly in this embodiment includes an active connecting rod 6, a passive connecting rod 7, a sliding rod 8, and a support plate 9 fixed on the test bench 1;

[0032] The first end of the active connecting rod 6 is connected to the driving member 5, the second end of the active connecting rod 6 is rotatably connected to the passive connecting rod 7, the second end of the passive connecting rod 7 is rotatably connected to the first end of the sliding rod 8, the second end of the sliding rod 8 is connected to the simulated human ear component, and the sliding rod 8 is slidably connected to the support plate 9.

[0033] It should be noted that the driving member 5 in this embodiment drives the active connecting rod 6 to rotate to drive the passive connecting rod 7 to swing, thereby driving the sliding rod 8 to reciprocate up and down in the vertical direction on the support plate 9, thereby simulating the movement posture of a human body when walking.

[0034] Furthermore, a slide rail 10 extending in a vertical direction is provided on the support plate 9 in this embodiment, and the slide rod 8 is slidably connected to the slide rail 10 .

[0035] It should be noted that, through the above design, it can be ensured that the sliding rod 8 can only move in the vertical direction, and the stability of the sliding rod 8 when it reciprocates up and down can be improved, thereby improving the test accuracy of the test equipment.

[0036] Furthermore, the passive connecting rod 7 is provided with an adjusting slot 11 along its length direction, the adjusting slot 11 is slidably connected with an adjusting portion 12 , and the second end of the active connecting rod 6 is rotatably connected to the adjusting portion 12 .

[0037] It should be noted that the above design allows the amplitude of the up-and-down reciprocating motion of the simulated human ear component to be adjustable. Specifically, when the tester moves the adjustment portion 12 to the lowest position of the adjustment slot 11, the amplitude of the up-and-down reciprocating motion of the simulated human ear component is the largest. Conversely, when the tester moves the adjustment portion 12 to the highest position of the adjustment slot 11, the amplitude of the up-and-down reciprocating motion of the simulated human ear component is the lowest.

[0038] The above design can simulate different walking ranges of real people and the normal movement state of the human body (that is, when the human body starts or stops walking, it does not immediately reach the moving or stopping state, but actually needs to slowly accelerate or decelerate to walk or stop at a normal speed). This effectively improves the accuracy of the test.

[0039] Furthermore, the simulated human ear assembly in this embodiment includes a connecting rod 4 and a simulated left ear 3 and a simulated right ear 2 respectively connected to opposite ends of the connecting rod 4;

[0040] The middle portion of the connecting rod 4 is connected to the reciprocating transmission assembly.

[0041] It should be noted that, since the left ear and the right ear of a real person are symmetrical structures, the reciprocating transmission assembly is specifically connected to the middle part of the connecting rod 4 so that the test equipment can simulate a real person as much as possible.

[0042] Furthermore, the simulated right ear 2 and the simulated left ear 3 in this embodiment are both artificial silicone ears made of silicone material.

[0043] It should be noted that the role of artificial silicone ears is to simulate the softness and wearing method of human ears, making the simulation effect more realistic and preventing other vibrations from affecting the sensors inside the earphones, causing abnormal step estimation.

[0044] Furthermore, a control circuit is installed in the test bench 1 in this example, and the control circuit is electrically connected to the driving member 5;

[0045] A switch button is installed on the outer surface of the test bench 1, and the switch button is electrically connected to the control circuit;

[0046] A speed regulating button is installed on the outer surface of the test bench 1, and the speed regulating button is electrically connected to the control circuit;

[0047] It should be noted that, in the present embodiment, the tester can control the driving component 5 to turn on or off through the control circuit by pressing the switch button. In addition, the tester can control the running speed of the driving component 5 through the control circuit by pressing the speed adjustment button, thereby simulating the scene of a human body walking at different speeds while wearing headphones.

[0048] Furthermore, during the actual test process, the test device in this embodiment can quickly test whether the pedometer function of the earphone is normal. During the actual application process, the test of a pair of earphones can be completed in about 20 seconds.

[0049] The test equipment can realistically simulate a human walking scene, with adjustable speed and amplitude, and fixed speed and amplitude during the test process.

[0050] The test equipment can quickly detect the consistency and accuracy of the headphone pedometer function. It mainly judges whether the headphone pedometer function is accurate by comparing the up and down reciprocating times of the simulated human ear component with the headphone pedometer times.

[0051] In addition, the test equipment is highly versatile and can be applied to most electronic products with pedometer functions.

[0052] The above is a detailed introduction to the test equipment provided by the present invention for simulating human walking to verify the pedometer function of headphones. For those skilled in the art, according to the idea of ​​the embodiments of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
