Specifically, the limiting structure 101 has at least 2 limiting grooves 102 in the limiting structure 101, and each limiting groove 102 is used for placing one to-be-tested earphone 103. The number of the limiting grooves 102 is the same as the number of the earphones 103 to be tested which can be tested at one time, and if the number of the limiting grooves 102 is too large, the problem that the frequency of the test signal is interfered may be caused; if the number of the limiting grooves 102 is too small, the testing efficiency will be affected. In one example, the number of the limiting grooves 102 may be 2 to 10, such as 4, 6, or 8.

It should be noted that, in other embodiments, the limiting clamp and the limiting base may also be non-detachable structures, for example, the limiting clamp and the limiting base may be an integrated structure.

In addition, the top of the position-limiting groove 102 may be flush with the top of the position-limiting clamp 111, or, as shown in fig. 3, the top of the position-limiting groove 102 may be higher than the top of the position-limiting clamp 111.

The electrical connection structure 104 is partially located in the limiting clamp 111 to realize the electrical connection between the electrical connection structure 104 and the earphone connection line of the earphone 103 to be tested. It is understood that the number of the electrical connection structures 104 is greater than or equal to the number of the earphones 103 to be tested, or the number of the electrical connection structures 104 is at least equal to the number of the limiting grooves 102, so as to ensure that each limiting groove 102 or each earphone 103 to be tested corresponds to one electrical connection structure 104.

In addition, the electrical connection structure 104 is further led out through the limiting base 121, and the electrical connection structure 104 led out through the limiting base 121 is used for being electrically connected with the signal control module 106, so that the electrical connection between the signal control module 106 and the earphone connection line of each earphone 103 to be tested is realized.

It is understood that, in other embodiments, the positioning hole may be disposed on the fourth end surface, and correspondingly, the positioning pin is disposed on the second end surface.

Fig. 6 is a schematic diagram of an electrical connection structure, referring to fig. 1-3 and fig. 6 in combination, the electrical connection structure 104 includes an electrically connected communication pair plug 114 and a headset control line 124; the communication pair plug 114 includes: the first communication pair plug 134 is positioned at the bottom of the limiting groove 102 and is used for being electrically connected with an earphone connecting line of the earphone 103 to be tested; the second communication pair plug 144, the second communication pair plug 144 is located at the limiting base 121 and is used for electrically connecting with the first communication pair plug 134; the earphone control line 124 is located on the limiting base 121 and led out from the limiting base 121, and the earphone control line 124 is electrically connected with the second communication pair plug 144 for connecting the signal control module 106.

The plug 114 is connected with the earphone connecting line through communication, so that the earphone 103 to be tested can be controlled to transmit the test signal through the signal control module 106. Specifically, after the earphone 103 to be tested is placed in the limiting groove 102, the earphone connecting line of the earphone 103 to be tested is in contact with the first communication pair plug 134 so as to establish connection; the first communication pair plug 134 contacts the second communication pair plug 144 to establish a connection, and the second communication pair plug 144 contacts the headset control wire 124 to establish a connection.

In this embodiment, the communication pair plug 114 includes the first communication pair plug 134 located in the limiting clamp 111 and the second communication pair plug 144 located in the limiting base 121, so as to meet the detachable requirement of the limiting clamp 111 and the limiting base 121, and the communication pair plug 114 is not damaged due to the detachment between the limiting clamp 111 and the limiting base 121. It is understood that in other embodiments, the communication pair plug may be an integral structure if the position limiting clamp and the position limiting base are not required to be designed as detachable structures.

In addition, the number of the earphone control lines 124 is the same as that of the limiting grooves 102, or the number of the earphone control lines 124 is greater than or equal to that of the earphones 103 to be tested in one test.

As shown in fig. 6, in one example, the first communication pair plug 134 may include: a first metal electrode 21 for connecting the second communication pair plug 144; the first pogo pin 22 is used for connecting the earphone 103 to be tested, and the first pogo pin 22 is fixed on the first metal electrode 21.

The second communication pair plug 144 may include: a second metal electrode 23 for connecting the earphone control line 124; and a second pogo pin 24 for connecting the first communication pair plug 134, and the second pogo pin 24 is fixed on the second metal electrode 23. Specifically, the second pogo pin 24 is used to connect the first metal electrode 21.

Specifically, when the earphone 103 to be tested is placed in the limiting groove 102, the earphone 103 to be tested abuts against the first spring pin 22, so that the first spring pin 22 is in contact with an earphone connecting line of the earphone 103 to be tested to establish electrical connection, and the first spring pin 22 is electrically connected with the first metal electrode 21; the second pogo pin 24 abuts against the first metal electrode 21 so that the second pogo pin 24 abuts against the first metal electrode 21 to establish electrical connection, and the second pogo pin 24 is electrically connected with the second metal electrode 23. And the second metal electrode 23 is connected with the earphone control wire 124, so that the electric connection between the earphone control wire 124 and the earphone 103 to be tested is established.

More specifically, the position of each second pogo pin 24 corresponds to the position of a first metal electrode 21, and the first metal electrode 21 is exposed from the surface of the limiting clamp 111 facing the limiting base 121, so that each metal electrode 21 can contact with a second pogo pin 24; wherein, the first metal electrode 21 may have a hole facing the second pogo pin 24, and after the limiting clamp 111 is assembled with the limiting base 121, the second pogo pin 24 extends into the hole to contact with the first metal electrode 21. In addition, the second metal electrode 23 may also be exposed from the surface of the limiting base 121 far away from the limiting clamp 111 to be electrically connected with the earphone control line 124; alternatively, the second metal electrode 23 may be located in the limiting base 121, and the earphone control wire 124 is partially located in the limiting base 121 to contact with the second metal electrode 23.

Because the first communication pair plug 134 comprises the first spring pin 22, and the first spring pin 22 has the characteristics of conductivity and length scalability, the same limiting clamp 111 can be suitable for the earphones 103 to be tested with different sizes, so that the earphones 103 to be tested with different sizes can be in contact with the first spring pin 22 to realize electrical connection. Likewise, since the second communication pair plug 144 includes the second pogo pin 24, the second pogo pin 24 has the characteristics of electrical conductivity and length scalability, when different position limiting fixtures 111 are mounted on the position limiting base 121, it can be ensured that the second pogo pin 124 has excellent electrical contact with the first metal electrode 21, thereby being beneficial to further improving the test accuracy.

In addition, limit structure 101 may further include: the limiting upper cover 131 is used for pressing the end face, far away from the limiting base 121, of the limiting clamp 111 so as to apply pressure towards the limiting base 121 to the earphone 103 to be tested. The limited upper cover 131 applies pressure to the earphone 103 to be tested, so that good electric contact between the earphone 103 to be tested and the first communication pair plug 134 can be further ensured in the test process.

Fig. 7 is a schematic view of another disassembled structure of the limiting structure, the electrical connection structure and the limiting upper cover in the detection apparatus, and for convenience of illustration and description, in fig. 7, the second communication pair plug 144 is separated from the limiting base 121, and the actual second communication pair plug 134 is located in the limiting base 121 and exposed from the limiting base 121 toward the surface of the limiting clamp 111.

Specifically, as shown in fig. 7, the first communication pair plug 134 located in each of the retaining grooves 102 includes: the first pogo pin 22 and at least 2 first metal electrodes 21 located on a side of the first pogo pin 22 away from the to-be-tested earphone 103 are provided, and a space is provided between adjacent first metal electrodes 21. The second communication pair plug 144 includes: the second metal electrodes 23 and at least 2 second pogo pins 24 located on each second metal electrode 23, and there is a space between adjacent second pogo pins 24, and each second pogo pin 24 is used to contact with a first metal electrode 21.

The limiting groove 102 penetrates through the limiting clamp 121, and the first metal electrode 21 may be located in the limiting groove 102 or may protrude from the surface of the limiting clamp 121 far away from the limiting upper cover 131. The second pogo pins 24 are located in the limiting base 121, and the surface of the limiting base 121 facing the limiting fixture 111 exposes the second pogo pins 24, so as to ensure that each second pogo pin 24 can contact with a corresponding first metal electrode 21. Specifically, the end surface of the second pogo pin 24 facing the first metal electrode 21 may protrude from the surface of the limiting base 121 facing the limiting fixture 111, and the end surface of the second pogo pin 24 facing the first metal electrode 21 may also be located on the surface of the limiting base 121 facing the limiting fixture 111, or the end surface of the second pogo pin 24 facing the first metal electrode 21 may also be located on the surface of the limiting base 121 facing the limiting fixture 111, so as to ensure that the end surface of the first metal electrode 21 and the end surface of the second pogo pin 24 can contact with each other.

The surface of the spacing base 121 away from the spacing clip 111 may expose the second metal electrode 23 to facilitate the earphone control wire (not shown) to be electrically connected with the corresponding second metal electrode 23. In addition, the second metal electrode 23 can also be located in the limiting base 121, and correspondingly, the earphone control wire is also partially located in the limiting base 121, so that the earphone control wire is electrically connected with the corresponding second metal electrode 23.

The signal control module 106 is configured to control the to-be-tested earphones 103 to transmit the test signals at different frequency points, so as to avoid mutual interference caused by the fact that a plurality of to-be-tested earphones 103 transmit the test signals at the same time, and ensure that each of the to-be-tested earphones 103 can be identified. In one example, the signal control module 106 may be a pc (personal computer) machine.

The signal acquisition and analysis module 107 is configured to acquire a test signal sent by each to-be-tested earphone 103, and analyze the test signal to judge whether the performance of the corresponding to-be-tested earphone 103 meets the requirement.

Specifically, in one example, the signal acquisition and analysis module 107 may include: a plurality of coupling plates (antenna coupler)117, and the number of the coupling plates 117 is half of the number of the earphones 103 to be tested; each coupling plate 117 is used for detecting the test signals of the two adjacent positions of the headset under test 103 and acquiring corresponding test data. The method can also comprise the following steps: and the frequency spectrograph is connected with the plurality of coupling plates 117 and is used for displaying the test data of each earphone 103 to be tested.

The coupling plate 117 receives the test signal and converts the test signal into electrical energy and generates test data, and the electrical energy converted by different test signals will be different. In this embodiment, each coupling board 117 is used to receive the test signal sent by 2 earphones 103 to be tested, so as to save the number of the coupling boards 117. It will be appreciated that in order to improve the accuracy of the test signals received by the coupling plate 117, the coupling plate 117 may be used to detect the test signals of two adjacent positions of the headset under test 103. It can also be understood that if the number of the earphones 103 to be tested in one test is n and n is an odd number, the number of the coupling plates 117 is (n + 1)/2.

In addition, in order to further improve the accuracy of the coupling plates 117 receiving the test signal, each coupling plate 117 is disposed opposite to the maximum radiation power direction of the corresponding earphone 103 to be tested.

It should be noted that, in other embodiments, the number of the coupling boards may be the same as the number of the earphones to be tested, that is, each coupling board receives the test signal transmitted by one earphone to be tested.

The detection device may further include a shielding box 108, and the limiting structure 101 and the coupling plate 117 are located in the shielding box 108, and are used for shielding external interference, ensuring stability of the test environment, and further improving accuracy of the test.

In the detection device provided by this embodiment, the limiting structure 101 has a plurality of limiting grooves 102 for placing the earphones 103 to be tested, and the electric connection structure 104 is used to electrically connect the signal control module 106 with the earphone connecting line of the earphones 103 to be tested; the signal control module 106 is configured to control the to-be-tested earphones 103 to transmit the test signals, and the frequencies of the test signals transmitted by the to-be-tested earphones 103 are different, so that mutual interference between the test signals of the to-be-tested earphones 103 is avoided, and the signal acquisition and analysis module 107 can accurately position the unqualified to-be-tested earphones 103. That is to say, the embodiment can simultaneously realize the test of the to-be-tested earphone 103, thereby improving the test efficiency and shortening the test time.

The present invention further provides a testing method, which is performed by using the above-mentioned detection apparatus, and the following detailed description will be made on the testing method provided in the embodiment of the present invention with reference to the accompanying drawings, where it is to be noted that the same or corresponding portions as those in the foregoing embodiment may be referred to the foregoing embodiment, and detailed description will not be repeated below. Fig. 8 is a schematic flowchart of a testing method according to an embodiment of the present invention.

And S101, providing a detection device and a plurality of earphones to be detected, wherein each earphone to be detected is fixed on the limiting structure, and the earphone connecting wire of each earphone to be detected is connected with the signal control module through the electric connection structure.

Specifically, a plurality of earphones to be tested are placed in a limiting groove of a limiting clamp, and then the limiting clamp is assembled on a limiting base; the plug is connected with the earphone connecting line and the earphone control line through communication, so that the earphone to be tested can be controlled to send out a test signal through the signal control module.

In one example, 4 headsets to be tested may be tested at a time. The headset to be tested may be a wireless headset, for example a bluetooth headset.

Step S102, the signal control module controls the earphones to be tested to send out test signals, and the frequency of the test signals sent out by each earphone to be tested is different.

Specifically, in order to avoid mutual interference caused by the fact that a plurality of earphones to be tested simultaneously transmit signals to be tested, the signal control module controls the earphones to be tested to transmit the signals to be tested at different frequency points. For example, in one example, a first headset under test transmits a test signal at the 2402MHz frequency point, a second headset under test transmits a test signal at the 2404MHz frequency point, a third headset under test transmits a test signal at the 2406MHz frequency point, and a fourth headset under test transmits a test signal at the 2408MHz frequency point.

And S103, acquiring and analyzing a test signal sent by the earphone to be tested by using the signal acquisition module.

The testing method provided by the embodiment can be used for testing whether the antenna performance of the earphone to be tested is abnormal, for example, the antenna performance of the earphone to be tested is tested by using an antenna coupling testing principle.

Specifically, after the earphone to be tested successfully transmits the test signal, the coupling plates acquire the value in a preset frequency band, capture the peak value of the frequency peak corresponding to each earphone to be tested through the frequency spectrum, process the average value of a plurality of power values read by the coupling plates at each frequency point, and record the average value as the test value of the coupling power of the earphone to be tested transmitting the frequency point. Thus, the coupling power test value of each earphone to be tested is obtained.

Judging whether the coupling power test value is within a set threshold, and if so, determining that the earphone to be tested corresponding to the coupling power test value is a qualified product; if the coupling power test value is not within the set threshold, the earphone to be tested corresponding to the coupling power test value is determined to be a unqualified product. The detection device can be provided with a display instrument for displaying the judgment result, and can independently display the test data and the coupling power test value corresponding to each earphone to be tested, so that the earphone which fails the test can be quickly positioned; the display may be a spectrometer.

The testing method provided by the embodiment can test the antenna performance of the earphones to be tested at one time, and ensures that the testing of the earphones to be tested does not influence each other, thereby being beneficial to shortening the testing time.

In addition, during the test, another batch of earphones to be tested can be placed in another set of limiting fixture, after the test of the current round is completed, the limiting fixture is directly removed from the limiting base, then a new limiting fixture is placed on the limiting base, and the next round of test can be started, so that the test efficiency can be further improved, and the test time can be saved.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
