[0029] The present application provides a testing device. The present application also provides a testing device system including the above-mentioned testing device.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] like Figure 1 As shown, the embodiment of the present application provides a test device, which is used to detect the waterproof performance of a speaker 10. The speaker 10 is not limited here. The speaker 10 can be a speaker 10 of 3C products such as mobile phones and computers, or a speaker 10 of products such as automobiles. The test device mainly includes a test container 1 and a liquid level detection member 2. Among them, the test container 1 is used to contain the test liquid. Since the test container 1 is used to test the waterproof performance of the speaker 10, the test liquid is usually water; the test container 1 is provided with a placement hole, and the speaker 10 is installed in the placement hole. The placement hole is set so that the part to be tested of the speaker 10 can be placed in the test container 1; the speaker 10 is sealed and connected to the test container 1. A rubber ring is exemplarily set between the speaker 10 and the placement hole to achieve a sealed connection between the speaker 10 and the test container 1. Such a setting can prevent the test liquid from flowing out of the gap between the speaker 10 and the placement hole, so as to improve the accuracy of the test of the waterproof performance of the speaker 10; the speaker 10 is installed on the placement hole of the test container 1 so that the part to be tested of the speaker 10 is in contact with the test liquid, so as to achieve the test of the waterproof performance of the speaker 10. With such arrangement, if the liquid level of the test liquid in the test container 1 decreases within the test time, it indicates that the speaker 10 is leaking; if the liquid level of the test liquid in the test container 1 does not decrease within the test time, it indicates that the speaker 10 is not leaking.

[0032] In addition, the liquid level detection member 2 is used to detect the change of the liquid level of the test container 1. By setting the liquid level detection member 2, the liquid level of the test liquid in the test container 1 can be detected in real time. With this setting, there is no need for the operator to observe in real time whether the liquid level of the test liquid in the test container changes.

[0033] Exemplarily, the liquid level detection component 2 can be a camera, a photoelectric sensor or the like.

[0034] The test device of the above structure is provided with a test container 1 for containing the test liquid, and a placement hole is provided in the test container 1. The speaker 10 is installed in the placement hole and is sealed and connected to the test container 1, so that the tested part of the speaker 10 is in contact with the test liquid. In this way, after recording the initial liquid level of the test container 1, the waterproof test of the speaker 10 is performed within a period of time. By observing whether the liquid level of the test container 1 decreases, it is possible to detect whether the speaker 10 is leaking, and the waterproof performance of the speaker 10 can be quantitatively determined according to the amount of liquid level drop. Such a setting can save labor during measurement, improve measurement efficiency, and the test results can also be quantitative. Moreover, a liquid level test piece for detecting the change of the liquid level of the test container 1 is provided, which can conveniently and in real time detect the change of the liquid level of the test container 1, avoiding the operator from observing the liquid level of the test container 1 in real time, further saving labor, and improving the accuracy of liquid level measurement.

[0035] In some embodiments, the test container 1 includes a first part 101 and a second part 102 that are interconnected, and the cross-sectional area of ​​the first part 101 is larger than the cross-sectional area of ​​the second part 102, and the height of the second part 102 is higher than the height of the first part 101. The speaker 10 is arranged on the wall surface of the first part 101, and the liquid level detection part 2 is used to detect the liquid level of the second part 102. Specifically, when the waterproof performance of the speaker 10 is detected by the test container 1, the specific steps are as follows: first, the speaker 10 to be tested is placed on the placement hole so that the speaker 10 is sealed and connected to the test container 1, and the part to be tested of the speaker 10 is located in the test container 1; then, the test liquid is injected into the test container 1. Since the cross-sectional area of ​​the first part 101 is larger than the cross-sectional area of ​​the second part 102, and the height of the second part 102 is higher than the height of the first part 101, the test liquid will first fill the first part 101 and then fill the second part 102 until the test liquid reaches the target liquid level height of the test container 1; then, the test container 1 is left stationary to perform a waterproof test on the speaker 10; finally, whether the speaker 10 is waterproof is detected by the change in the liquid level of the test liquid in the test container 1 before and after the test.

[0036] Here, since the height of the second part 102 is higher than that of the first part 101, it is possible to observe whether the speaker 10 is leaking by observing the change in the liquid level of the second part 102, and further ensure that the cross-sectional area of ​​the first part 101 is larger than the cross-sectional area of ​​the second part 102. In this way, when the speaker 10 is leaking, compared with the technical solution in which the cross-sectional areas of the first part 101 and the second part 102 are the same, when the detection liquid drops by the same volume, the drop in the liquid level of the second part 102 will be larger, so as to facilitate the detection of the liquid level by the liquid level detection element 2. Moreover, such a configuration also facilitates the installation of the speaker 10 on the test container 1.

[0037] Exemplarily, the test container 1 may be in an L-shape, a V-shape, a U-shape, an inverted T-shape, a J-shape, a Z-shape, or the like.

[0038] In some embodiments, a scale for measuring the liquid level of the test liquid is set on the wall of the test container 1. In this way, when the speaker 10 leaks when the test container 1 is used to test the waterproof performance of the speaker 10, the liquid level before and after the test can be easily identified by setting a scale on the wall of the test container 1, thereby improving the convenience of the liquid level test and accurately measuring the leakage amount of the speaker 10 to be tested.

[0039] Furthermore, since the cross-sectional area of ​​the first part 101 is larger than the cross-sectional area of ​​the second part 102, and the speaker 10 is arranged on the first part 101, when the speaker 10 leaks, usually only the liquid level of the second part 102 will change. Therefore, by locating the scale on the wall of the second part 102, the change in the liquid level of the test liquid in the test container 1 can be detected.

[0040] In some embodiments, the placement hole is disposed on the top side wall of the first portion 101. That is, the speaker 10 is mounted on the top side wall of the first portion 101. This arrangement facilitates the installation and removal of the speaker 10, and improves the test efficiency of the waterproofness of the speaker 10 to a certain extent.

[0041] In addition, the placement hole can also be set on other walls of the first part 101, that is, the speaker 10 can also be installed on other walls of the first part 101, so that the waterproof performance of the speaker 10 can also be tested.

[0042] In some embodiments, the starting position of the scale is located at the same horizontal plane as the placement hole, and the scale is set on the second part 102, that is, the scale position of the test liquid in the second part 102 is the same as the height of the test liquid level exceeding the speaker 10. In this way, when simulating different water depths, the scale position of the second part 102 corresponds to different water depth levels, so as to improve the convenience of testing the speaker 10 in different water depth environments.

[0043] In some embodiments, the test device further includes a liquid storage container 3, a liquid inlet pipe 4 and a liquid discharge pipe 5. The liquid storage container 3 is used to store the test liquid; the two ends of the liquid inlet pipe 4 are respectively connected to the liquid storage container 3 and the test container 1; the two ends of the liquid discharge pipe 5 are respectively connected to the liquid storage container 3 and the test container 1. Specifically, when the test device is used to test the waterproof performance of the speaker 10, after the speaker 10 is installed on the placement hole of the test container 1, the test liquid in the liquid storage container 3 is injected into the test container 1 through the liquid inlet pipe 4, and then the waterproof performance of the speaker 10 is tested within the target time through the test container 1. Finally, after the test is completed, the test liquid in the test container 1 is recovered into the liquid storage container 3 through the liquid discharge pipe 5. By providing the above-mentioned liquid storage container 3, liquid inlet pipe 4 and liquid discharge pipe 5, the test liquid can be recycled, so as to achieve the effect of saving the test liquid and save the test cost.

[0044] In some embodiments, the liquid inlet pipe 4 is connected to the top of the test container 1, and a pump 6 is provided in the liquid inlet pipe 4; the liquid discharge pipe 5 is connected to the bottom of the test container 1, and a stop valve 7 is provided in the liquid discharge pipe 5. It should be noted that this arrangement is a scenario in which the height of the liquid storage container 3 is lower than the test container 1. Specifically, when injecting the test liquid into the test container 1, the pump 6 in the liquid inlet pipe 4 is opened and the stop valve 7 in the liquid discharge pipe 5 is closed, so that the test liquid is quickly injected into the test container 1; when the test container 1 completes the test of the speaker 10, the stop valve 7 in the liquid discharge pipe 5 is opened and the pump 6 in the liquid inlet pipe 4 is kept in a closed state, so that the test liquid in the test container 1 is discharged into the liquid storage container 3. Such an arrangement can improve the efficiency of injecting the test liquid into the test container 1.

[0045] In addition, when the height of the liquid storage container 3 is higher than the test container 1, the liquid inlet pipe 4 and the liquid discharge pipe 5 are arranged in another way, for example: the liquid inlet pipe 4 is connected to the bottom of the test container 1, and a stop valve 7 is arranged in the liquid inlet pipe 4; the liquid discharge pipe 5 is connected to the top of the test container 1, and a pump 6 is arranged in the liquid discharge pipe 5. In this way, the effect of liquid inlet and liquid discharge to the test container 1 can also be achieved.

[0046] In addition, in order to further improve the efficiency of liquid inlet and liquid discharge of the test container 1 , pumps 6 may also be provided in both the liquid inlet pipe 4 and the liquid discharge pipe 5 .

[0047] In some embodiments, the test device further includes a time recorder 8 for recording and displaying the test time. Here, the time recorder 8 can record and display multiple time information. Specifically, in the process of using the test device to test the waterproof performance of the microphone, the time recorder 8 will record the time when the test starts, the time when the test liquid is injected, the time when the water level starts to change, the time when the test is completed, etc. will be recorded separately, and the test time can be displayed in real time. By setting the above-mentioned time recorder 8, it is possible to conveniently record and display the time during the test process, so that the test efficiency of the test device for the waterproof performance of the microphone can be further improved, and the quantitative test of the waterproof performance of the microphone can be conveniently achieved according to the time when the water level starts to change recorded by the time tester.

[0048] In some embodiments, the test device includes a controller 9 that is respectively connected to the time recorder 8 and the liquid level detection element 2 to send out an alarm message when the test liquid level changes, and to make the time recorder 8 record the time information at this time. Among them, the controller 9 adopts PLC programming to realize the automatic control of the entire test process, which exemplarily includes the following steps: installing the speaker 10 to be tested into the placement hole of the test container 1; starting the water injection system according to the test water level requirements to simulate different water depth environments; when the water level reaches the initial liquid level of the test, the time recorder 8 starts to record the time; when the liquid level detection element 2 detects the change in the liquid level of the test liquid, it sends an alarm message to the tester and synchronously records the corresponding time, and the system continues to test; after the test reaches the specified time, the liquid level detection element 2 records the final liquid level information; after the test is over, the controller 9 controls the opening of the stop valve 7 to recover the test liquid into the liquid storage container 3; analyze the data and evaluate the waterproof performance of the speaker 10. Furthermore, during the test, when the liquid level detection component 2 detects a change in the liquid level of the test liquid, the information is sent to the controller 9, and the controller 9 sends a signal to the time recorder 8, which records the moment when the liquid level changes. Such a setting can further improve the degree of automation of the test device in testing the waterproof performance of the speaker 10.

[0049] In some embodiments, at least a portion of the test container 1 is made of a transparent material to make the test liquid visible. In this way, the liquid level detection element 2 can quickly and efficiently detect the liquid level of the test container 1 and can more sensitively detect the moment when the liquid level in the test container 1 changes.

[0050] It should be noted that at least a portion of the test container 1 is made of a transparent material, which means that at least a portion of the test container 1 where the scale is set is made of a transparent material, so as to facilitate the detection of the liquid level of the test liquid in the test device.
