Under the attraction of the magnet, the metal sheet drives the touch spring to return to its initial state; when the rate of change of the direction of the magnetic field generated by the magnet reaches 2 to 3 times within 1 second, the time interval for the touch spring to form a touch point and return to the initial state is shortened, so that a double-click or triple-click operation can be performed on the same touch point in a short time.

[0027] As can be seen from the background technology, currently the earphone testing device can only perform touch test on a single point of the earphone, but cannot perform touch test on multiple areas of the earphone.

[0028] The present application provides an earphone touch test device, which can achieve the purpose of testing the touch performance of the earphone. By using multiple touch structures, touch control of multiple points of the earphone can be achieved, thereby improving the comprehensiveness of the test.

[0029] The following will describe the various embodiments of the present application in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present application, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in the present application can be implemented.

[0030] Figure 1 and Figure 2 This is a schematic diagram of the appearance and structure of the headphone touch test device provided in an embodiment of the present application.

[0031] refer to Figure 1 and Figure 2 The earphone touch test device provided in the embodiment of the present application includes: a fixture 101, having a receiving cavity for fixing the earphone; a cover plate 102, the cover plate 102 is located above the fixture 101, and the cover plate 102 is provided with a plurality of touch structures 106 facing the receiving cavity. The touch structures 106 can be deformed from an initial state along a direction approaching the receiving cavity to form a touch point protruding toward the receiving cavity, and return to the initial state after the touch point is formed.

[0032] The earphone touch test device provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0033] During the headphone test, the headphone is fixed by the fixture 101 to prevent shaking during the test from affecting the test results; multiple touch structures 106 are arranged in the cover plate 102, and touch operations can be performed on different points of the headphone through the multiple touch structures 106 to improve the comprehensiveness of the test. Among them, the point refers to the position of the touch point formed by the touch operation on the headphone.

[0034] The earphones include but are not limited to wireless earphones or wired earphones, wherein the wireless earphones may be Bluetooth earphones. The earphones may also be dynamic earphones, moving iron earphones, dynamic iron earphones, isomagnetic earphones, electrostatic earphones, electret earphones, etc.

[0035] The clamp 101 can be made of metal, plastic or rubber. The shape of the clamp 101 can be designed according to the structure of the earphone, and the accommodating cavity of the clamp 101 can be designed according to different earphone shapes to achieve the purpose of fixing the earphone.

[0036] Figure 3 A schematic diagram of the fixture structure of the headphone touch test device provided in an embodiment of the present application.

[0037] In some embodiments, reference Figure 3 The fixture 101 may include: an ear stem fixing portion 103, the ear stem fixing portion 103 has a first accommodating area for accommodating the ear stem; an ear bag fixing portion 104, the ear bag fixing portion 104 has a second accommodating area for accommodating the ear bag, the first accommodating area and the second accommodating area are connected to form the accommodating area, and the material of the ear bag fixing portion 104 is a conductive material. The conductive material used in the ear bag fixing portion 104 can simulate the state of the earphone when it is in the ear, more realistically simulate the situation of the earphone in actual use, and avoid the decrease in the accuracy of the touch test results due to the error of the earphone in judging the state. It is understandable that the earphones have different shapes. For the convenience of distinguishing, the description is composed of an ear stem portion and an ear bag portion. The ear bag portion is a contact material for expressing the identification of the earphone in the ear or wearing mode, and the shape of the earphone is not limited to being composed of an ear stem and an ear bag. The earphone can also be a head-mounted earphone.

[0038] Figure 4 A schematic cross-sectional structure diagram of an earphone that can be placed in an earphone touch test device provided in an embodiment of the present application.

[0039] refer to Figure 4 The volume of the first accommodation area can be 1 / 4 to 3 / 4 of the volume of the earphone. It can be understood that the touch area 105 of the earphone is usually at the ear stem. It is sufficient to ensure that the touch area 105 of the earphone is exposed by the fixture 101 after the earphone is placed in the first accommodation area and the second accommodation area. Therefore, the size of the ear stem fixing part 103 can be designed according to the shape and size of different earphones to ensure that the ear stem is fixed and the touch area 105 of the earphone is exposed, so as to facilitate touch operation.

[0040] The cover plate 102 may be made of metal, plastic or rubber. The cover plate 102 may be fixed on the top of the fixture 101, and the cover plate 102 and one end of the fixture 101 may be fixed by a rotating bearing to form a flip cover structure, such as Figure 1 The cover plate 102 is covered on the fixture 101. Figure 2 The cover plate is in an open state above the fixture 101. In addition, in other embodiments, a rotation bearing may not be provided between the cover plate 102 and the fixture 101, and the cover plate 102 may be removed as a whole to separate the cover plate 102 from the fixture 101, so as to facilitate the adjustment of the touch structure 106 in the cover plate 102, and the cover plate 102 may also be buckled on the fixture 101. It is understandable that the shape of the cover plate 102 can be designed according to different earphone shapes to cover different touch areas 105 of different earphones, thereby achieving the purpose of testing the touch function of the earphone.

[0041] The distribution of the multiple touch structures 106 in the cover plate 102 can be set according to the different test requirements of the earphone points, that is, according to the position of the point where the earphone is to be touch-tested, the position of different touch structures 106 is set to ensure that each touch structure 106 can perform touch operations on the corresponding point. For example, when the different points of the earphone are distributed around the outer circumference of the earphone ear rod, the multiple touch structures 106 can be distributed along the cross section of the earphone ear rod around the outer circumference of the earphone ear rod to achieve coverage of different touch areas 105 in the direction of the cross section of the outer circumference of the earphone ear rod; or, when the different points of the earphone are distributed along the length direction of the ear rod, the multiple touch structures 106 are distributed along the length direction of the earphone ear rod to achieve coverage of different touch areas 105 in the length direction of the earphone ear rod. It can be understood that the number of touch structures 106 can be set according to the different test requirements of the earphone, and different numbers of touch structures such as 2, 3, 5 or 8 can be set.

[0042] Figure 5 and Figure 6 This is a schematic cross-sectional structure diagram of the headphone touch test device provided in an embodiment of the present application.

[0043] In some embodiments, reference Figure 5 and Figure 6 ,in, Figure 5 A schematic cross-sectional view of the touch control structure 106 in the initial state, Figure 6 The cross-sectional structure diagram of the touch control structure 106 corresponding to the touch point is shown in FIG. Figure 5 and Figure 6The touch structure 106 may include: a magnet 107, which is fixed to the inner wall of the cover plate 102 facing the accommodating cavity, and the magnetic field strength and magnetic field direction of the magnetic field generated by the magnet 107 are adjustable; a metal sheet 108, which is arranged on the side of the magnet 107 facing the accommodating cavity, and the metal sheet 108 can protrude toward the accommodating cavity under the action of the magnetic field generated by the magnet 107; a touch spring 109, which is arranged on the side of the metal sheet 108 facing the accommodating cavity, and the side of the touch spring 109 away from the accommodating cavity is fixed to the metal sheet 108.

[0044] In the touch structure 106, the direction and strength of the magnetic field generated by the magnet 107 are adjustable, so that it can generate an attractive force or a repulsive force on the metal sheet 108, so as to drive the touch spring 109 to deform to form a touch point or return to the initial state. Figure 6 When the metal sheet 108 is repelled by the magnetic field generated by the magnet 107, the metal sheet 108 is subjected to a force toward the accommodating cavity, thereby driving the touch spring 109 to deform toward the accommodating cavity, so that the touch point formed by the touch spring 109 contacts the touch area 105 of the earphone to form a touch. Figure 5 When the direction of the magnetic field generated by the magnet 107 is opposite, the metal sheet 108 is attracted by the magnetic field generated by the magnet 107, and the metal sheet 108 is sucked back to the surface of the magnet 107, so that the touch spring 109 is brought back to the initial state by the metal sheet 108 and leaves the earphone touch area 105, thereby forming a touch operation. In addition, the intensity of the magnetic field generated by the magnet 107 is adjustable, that is, the magnitude of the force exerted by the magnetic field on the metal sheet 108 is adjustable. When the force of the magnetic field is large, the repulsive force or attractive force exerted by the magnetic field on the metal sheet 108 becomes larger, and the force exerted by the touch spring 109 on the earphone touch area 105 also increases, thereby satisfying the touch test under the condition of poor touch sensitivity of the earphone.

[0045] It should be noted that the initial state of the touch spring 109 deforming toward the side of the accommodating cavity or returning to the initial state is not limited to being exactly the same as the state before deformation. The restored position of the touch spring 109 may be slightly different from that before deformation, but it does not affect the next deformation of the touch spring 109 toward the side of the accommodating cavity. Therefore, the initial state does not limit the touch spring 109 and the metal sheet 108 to return to the same initial state position after each touch operation. As long as the touch structure 106 no longer has a touch point that touches the touch area 105, it can be considered that the touch structure 106 has returned to the initial state.

[0046] In other embodiments, the touch structure 106 may also be an electromechanical structure. For example, the touch structure 106 may include a motor and a contact head. One end of the contact head is connected to the motor. The rotation direction of the motor is adjustable. The rotation of the motor can drive the contact head to move toward the accommodating cavity or return to the initial state. For example, when the motor rotates in a first direction, the motor pushes the contact head to move toward the accommodating cavity and contacts the touch area 105 of the headset to form a touch point. When the motor rotates in a second direction opposite to the first direction, the contact head is brought back to the initial position, that is, the touch head in the touch structure can return to the initial state. For an explanation of the initial state, please refer to the above description, which will not be repeated here.

[0047] Figure 7 A schematic diagram of the touch control structure of the headphone touch control testing device provided in an embodiment of the present application.

[0048] In some embodiments, in conjunction with reference Figures 5 to 7 The magnet 107 may include: a magnetic core 111 and a power-carrying coil 110 wound around the outer circumference of the magnetic core 111, and the magnitude and direction of the current passing through the power-carrying coil 110 are adjustable.

[0049] By adjusting the direction of the current, the direction of the magnetic field generated by the magnet 107 can be changed, so that the metal sheet undergoes different deformations in different states, thereby driving the touch spring 109 to form a touch point or return to the initial state; by adjusting the current, the magnetic field strength of the magnetic field generated by the magnet 107 can be changed, thereby performing touch operations of different strengths on the headphone touch area 105. For example, when the magnetic core 111 is non-magnetic, the power-on coil 110 is not powered, and the magnetic core 111 has no magnetic force, and no force is applied to the metal sheet 108; when the power-on coil 110 is powered in the forward direction, the power-on coil 110 is powered in the forward direction, and ... Figure 6 , the magnetic core 111 generates a repulsive force on the metal sheet 108, the metal sheet 108 deforms toward the accommodation cavity, thereby driving the touch spring 109 to deform into the accommodation cavity, and the touch spring 109 contacts the touch area 105 of the headset to form a touch point; when the energized coil 110 is reversely energized, Figure 5, the metal sheet 108 is attracted by the magnetic core 111, and the metal sheet 108 is sucked back to the surface of the magnetic core 111. The metal sheet 108 brings back the touch spring 109, and the touch is ended, thereby forming a touch operation. At the same time, the conversion rate of the current direction can control the rate of conversion of the magnetic field direction generated by the magnetic core 111. When the conversion rate of the magnetic field direction reaches 2 to 3 times per second, a touch structure 106 can form two or three touch operations within 1 second, thereby achieving the effect of double-clicking or triple-clicking the headphone touch area 105. It can be understood that it is defined here that when the power is forwarded, the magnetic field generated by the coil is a repulsive force; when the power is reversed, the magnetic field generated by the powered coil is an attractive force, for the sake of ease of understanding. The direction of the magnetic field generated by the powered coil 110 is different due to different winding methods. Therefore, the fixed relationship between the winding method of the coil and the power-on direction is not limited, and the winding method and the power-on direction can be selected according to actual conditions.

[0050] In addition, multiple touch structures 106 can perform touch operations through different magnets 107. When the magnets 107 in two or three touch structures 106 generate repulsive force at the same time, the metal sheets 108 in the two or three touch structures 106 are deformed into the accommodating cavity at the same time, so that two or three touch springs 109 are driven to form touch points on the touch area 105 of the earphone at the same time. Therefore, touch operations can be performed on two or three touch points at the same time to achieve double-click or triple-click with different points.

[0051] In some other embodiments, the magnetic core 111 may be a magnetic core 111. When the energized coil 110 is not energized, Figure 5 , the magnetic core 111 will continue to adsorb the metal sheet 108 to the surface of the magnet 107; when the power coil 110 is energized, Figure 6 , the direction of the magnetic field generated by the coil is opposite to that of the magnetic core 111, thereby offsetting the magnetic force of the magnetic core 111 and generating a repulsive force on the metal sheet 108 toward the receiving cavity of the fixture 101. At this time, the metal sheet 108 drives the touch spring 109 to deform toward the receiving cavity; when the current of the energized coil 110 decreases or even disappears, Figure 5 , the magnetic field generated by the energized coil is reduced or disappears, and the magnetic force of the magnetic core 111 is greater than the magnetic field generated by the energized coil 110. At this time, the metal sheet 108 will be sucked back to the surface of the magnet 107, thereby driving the touch spring 109 back to the initial state, thereby achieving a touch operation. It can be understood that different winding methods of the energized coil can make the direction of the magnetic field generated by the energized coil 110 different. Therefore, the winding method of the coil and the fixedness of the direction of the generated magnetic field are not limited, and can be adjusted according to different needs.

[0052] In some embodiments, reference Figure 5 and Figure 6The earphone touch test device may further include: a partition 112, the partition 112 is fixed to the inner wall of the cover plate 102 facing the accommodating cavity, the partition 112 is used to isolate adjacent touch structures 106, and the end of the touch spring 109 is fixed on the partition 112. The partition 112 is arranged between adjacent touch structures 106 to prevent the touch structures 106 from affecting each other when the distance between them is too close, thereby causing operational errors. The partition 112 separates different touch structures 106 from each other, and different touch structures 106 can share the partition 112 to increase space utilization without interfering with each other. In addition, the touch springs 109 between adjacent touch structures 106 can be fixed on the same partition 112, and the touch springs 109 and the partition 112 separate the touch structures 106 in independent spaces adjacent to each other, which can increase the setting density of the touch structures 106.

[0053] In other embodiments, adjacent touch structures 106 may not share the partition 112, that is, the partition 112 of each touch structure 106 separates the touch structure 106 into an independent space, and the end of the touch spring 109 is fixed on the partition 112 of the touch structure 106 to which it belongs. Each touch structure 106 may be spaced apart, and the touch structure 106 is set for different touch points to avoid too many touch structures 106 covering the non-touch function area of ​​the headset, resulting in confusion caused by too many touch structures 106 and control operations.

[0054] Figure 8 Schematic diagram of the headphone testing device bracket provided in an embodiment of the present application.

[0055] In other embodiments, reference Figure 8 The fixture 101 of the headphone touch control device can be provided with a bracket 113, which can fix the fixture on the test bench to prevent the entire headphone touch control test device from shaking when the touch control structure 106 in the cover plate 102 is operated, thereby affecting the test process and results, and improving the stability of the entire headphone touch control test device. It can be understood that the schematic diagram of the bracket 113 device provided in the embodiment of the present invention does not limit the setting structure of the bracket 113, and other structures that can stabilize the headphone test device can be designed according to specific implementation conditions.

[0056] The earphone touch test device provided in the embodiment of the present application has a fixture 101 and a cover plate 102. A plurality of touch structures 106 are arranged on the inner wall of the cover plate 102 facing the accommodating cavity of the fixture 101. The touch structure 106 can be deformed from the initial state in the direction close to the accommodating cavity to form a touch point protruding toward the accommodating cavity, and return to the initial state after the touch point is formed. During the earphone test, the fixture 101 can fix the earphone to prevent shaking during the test from affecting the test results; the touch structure 106 is arranged in the cover plate 102, and the earphone is touched by the touch structure 106 to prevent inaccurate test results caused by errors in the touch position or frequency of the earphone during manual touch; and the number of touch structures 106 is multiple, so that touch tests at different positions of the earphone can be realized, that is, touch tests at different points of the earphone can be realized.

[0057] refer to Fig. 9 , is a schematic diagram of a test system provided in an embodiment of the present invention.

[0058] Accordingly, reference Fig. 9 The embodiment of the present application also provides a test system, including: the headset automatic touch test device provided in the above embodiment; a controller 114 and an electric box 115, wherein the controller 114 is used to control the electric box 115 to supply power to the touch structure 106.

[0059] The controller 114 may include a desktop computer, a laptop computer, or a mobile phone.

[0060] Accordingly, combined with reference Figure 5 , Figure 6 as well as Fig. 9 , the embodiment of the present application also provides a method for testing a test system, including: the controller 114 outputs a first control signal to the electric box 115, the electric box 115 outputs a first electrical signal to the touch structure 106 in response to the first control signal, the touch structure 106 forms a touch point in response to the first electrical signal to realize the touch operation of the earphone, and collects the test signal output by the earphone under the touch operation; after the touch operation is completed, the controller 114 outputs a second control signal to the electric box 115, the electric box 115 outputs a second electrical signal to the touch structure 106 in response to the second control signal, and the touch structure 106 returns to the initial state from the touch point in response to the second electrical signal. It can be understood that the method for testing the test system can be modified according to actual needs, and the description of this embodiment for ease of understanding does not set a fixed standard for the operation method.

[0061] In addition, the first control signal is a first current signal with adjustable magnitude and direction, and the second control signal is a second current signal with adjustable magnitude and direction, and the first current signal and the second current signal have opposite current directions. The magnitude and direction of the current signal are adjustable, making the test method more diversified to meet different needs. Figures 5 and 6 For example, when the speed of the direction change of the first current signal and the second current signal is 0.2 to 0.3 times / second, the magnetic field change of the magnet 107 in the touch structure 106 can reach 2 to 3 times per second. Therefore, in the same touch structure 106, the metal sheet 108 and the touch spring 109 can be deformed into the accommodation cavity and return to the initial state 2 to 3 times within 1 second due to the attraction and repulsion of the magnetic field. In other words, Figure 5 The structure shown is transformed to Figure 6 The structure shown returns to Figure 5 The structure shown is a single touch, which is repeated two or three times, thereby achieving the purpose of double-clicking or triple-clicking the same touch point. Among them, the first current signal can also send a control signal to multiple touch structures 106. For example, when the first current signal sends a control signal to two or three touch structures 106, after the first current signal passes through the power box, the power box provides power to the two or three touch structures 106, and the two or three touch structures 106 perform touch operations, so that two or three touch points are touched at the same time, achieving the situation where the double-click or triple-click points are different.

[0062] Those skilled in the art can understand that the above-mentioned embodiments are specific examples for implementing the present application, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present application. Any person skilled in the art can make their own changes and modifications without departing from the spirit and scope of the present application, so the scope of protection of the present application shall be based on the scope defined in the claims.
