Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pickup device testing, and particularly relates to a testing device and a testing method. BACKGROUND

[0002] A bone conduction microphone is a special pickup device, and its working principle is different from that of a traditional air conduction microphone. Instead of collecting air vibration, it converts an electrical signal by directly picking up the skull bone vibration caused by the vocal cord vibration when a person speaks. This feature enables it to provide clear and reliable voice input in harsh audio environments such as high environmental noise and strong wind, and thus it is widely used in military communication, fire rescue, outdoor sports earphones, and hearing aid devices.

[0003] The core evaluation indicators of the performance of a bone conduction microphone, such as frequency response, harmonic distortion, and sensitivity, directly determine the voice clarity and fidelity. However, due to its unique working principle, the traditional testing method based on an acoustic cavity and a reference air microphone is completely unsuitable. Some existing testing schemes test through a specially designed testing system that can simulate human bone vibration. However, a prominent problem in practice is that the accuracy and reliability of the test results are difficult to guarantee. Due to the lack of effective monitoring of the key states of the testing process itself, the real excitation conditions applied to the microphone under test by the testing system may be uncertain. This uncertainty will cause the measured frequency response, distortion, and other parameters to be unable to truly reflect the performance of the product itself, resulting in serious inaccuracy of the measurement values.

Thus, features defined with "first", "second" can include one or more of the features explicitly or implicitly.

[0033] In the present application, unless otherwise explicitly specified and limited, the "on" or "under" of the first feature to the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them.

[0034] Please refer to Figure 1 and Figure 2 , the embodiment of the present application provides a test device for detecting a pickup device 200, the test device comprises: a carrier 10 for carrying the pickup device 200; a vibrator 20 connected to the carrier 10 for driving the carrier 10 to vibrate, the pickup device 200 vibrates with the carrier 10 and generates a first sensing signal; a vibration sensor 30 arranged on the carrier 10, the vibration sensor 30 is used for sensing the vibration of the carrier 10 and generating a second sensing signal; a first detection structure 40, which is in communication connection with the pickup device 200, the first detection structure 40 is used for receiving the first sensing signal; and a second detection structure 50, which is in communication connection with the vibration sensor 30, the second detection structure 50 is used for receiving the second sensing signal and judging whether the signal strength of the second sensing signal is in a preset range; wherein, when the signal strength of the second sensing signal is in the preset range, the first detection structure 40 detects the first sensing signal.

[0035] It should be noted that the pickup device 200 of the embodiment of the present application is a bone conduction microphone, which picks up sound by collecting the vibration of human bones, such as the skull, rather than collecting air vibration like traditional microphones. When wearing a bone conduction microphone, the user's vocal cord vibration will be directly transmitted to the skull through the throat, mandible and other tissues, causing the skull to vibrate, and the piezoelectric ceramic or accelerometer sensor in the bone conduction microphone is in close contact with the skin, directly detecting these tiny bone vibrations and converting them into electrical signals. Of course, in other possible implementations, the pickup device 200 can also be other microphones that pick up sound by sensing vibration.

[0036] In the embodiment of the present application, the pickup device 200 vibrates with the carrier 10 and outputs a first sensing signal, the first detection structure 40 receives and detects the first sensing signal, thereby detecting the performance of the pickup device 200, such as frequency response, distortion and sensitivity, etc. The test process can simulate the skull bone vibration caused by the vocal cord vibration when the pickup device 200 picks up the human speech, so that the performance indicators of the pickup device 200 in normal operation can be truly reflected, thereby improving the accuracy of the test.

[0037] In the embodiment of the present application, the first detection structure 40 has the function of analyzing the first sensing signal generated after the pickup device 200 senses the vibration, and according to the preset data processing logic, the acoustic performance test results of the pickup device 200 can be obtained, such as frequency response, total harmonic distortion, sensitivity and other acoustic performance parameters. The first detection structure 40 can be any available electronic device with computing capability, such as any type of audio analysis instrument and computer, etc. Alternatively, the second detection structure 50 can also be an electronic device with computing capability, such as any type of audio analysis instrument and computer, etc.

[0038] It can be understood that the present application also includes a control system, the vibrator 20, the vibration sensor 30, the first detection structure 40 and the second detection structure 50 are in communication connection with the control system, and the control system can control the vibrator 20, the vibration sensor 30, the first detection structure 40 and the second detection structure 50 to automatically cooperate and operate.

[0039] In the embodiment of the present application, the second detection structure 50 can quickly diagnose whether the vibrator 20 is abnormal by judging whether the signal strength of the second sensing signal is in the preset range. Because when the vibrator 20 is abnormal, such as failure or loose connection, it will cause the signal strength of the second sensing signal to be too large or too small, so this abnormality can be clearly distinguished from the failure of the pickup device 200. This enables the operator to quickly locate the problem source, avoids tedious cross-checking between the test equipment and the measured product, greatly shortens the fault diagnosis time, improves the efficiency of the production quality inspection link, and reduces the maintenance cost of the equipment. Alternatively, the second sensing signal is an electrical signal. Alternatively, the preset range is 90mv~110mv.

[0040] It can be understood that the vibration sensor 30 detects the displacement, speed, acceleration and other parameters of the vibration body to provide data support for equipment state monitoring. Alternatively, the vibration sensor 30 is an acceleration sensor, a speed sensor or a displacement sensor, etc.

[0041] The test device provided in the application, the pickup device 200 vibrates with the carrier 10 and outputs a first sensing signal, the first detection structure 40 receives and detects the first sensing signal, so that the performance of the pickup device 200 can be detected, the test process can simulate the skull bone vibration caused by the vocal cord vibration when the pickup device 200 picks up the human speech, so that the performance index of the pickup device 200 in the normal working state can be truly reflected, thereby improving the accuracy of the test; and the vibration sensor 30 is arranged to sense the vibration of the carrier 10 in real time and generate a second sensing signal, and the second detection structure 50 judges whether the signal strength of the second sensing signal is in a preset range, so that the working state of the vibrator 20 can be effectively detected, and it is ensured that the first sensing signal is detected when the vibrator 20 is in the normal working state, thereby avoiding the measurement error caused by the abnormal state of the vibrator 20, and improving the reliability of the test.

[0042] In some embodiments, as shown in Figure 3 and Figure 4 The carrier 10 includes a connecting seat 11 connected to the vibrator 20 and a bearing part 12 connected to the connecting seat 11, the connecting seat 11 includes a support surface (not shown in the figure) for placing the vibration sensor 30, and the bearing part 12 is used to support the pickup device 200, and the bearing part 12 is arranged in a spaced manner with the support surface.

[0043] Optionally, the carrier 10 further includes a support block 15 connected to the support surface, the support block 15 is used to support the bearing part 12 to a preset height, so that the bearing part 12 is arranged in a spaced manner with the support surface. By arranging the support surface for mounting the vibration sensor 30 on the connecting seat 11, the vibration sensor 30 is closer to the vibrator 20 than the pickup device 200, so that the vibration sensor 30 is as close as possible to the driving point of the vibrator 20, and the original mechanical excitation input by the vibrator 20 can be most directly and least lossily monitored, thereby facilitating the detection of the working state of the vibrator 20. The bearing part 12 for supporting the pickup device 200 is arranged in a spaced manner with the support surface, which effectively avoids the mechanical interference of the installation of the pickup device 200 and its own quality on the monitoring area of the vibration sensor 30, thereby ensuring that the second sensing signal can purely reflect the “input excitation” and is not affected by the measured pickup device 200, thereby providing an abnormally stable and reliable reference signal for the entire test system.

[0044] In addition, the bearing part 12 is arranged in a spaced manner with the support surface of the connecting seat 11, which actually forms a specific vibration transmission path, the mechanical properties of the path can be accurately designed and controlled, thereby better simulating the vibration transmission characteristics in the real use environment of the bone conduction microphone, such as coupling with the skull through the skin, soft tissue, etc., which makes the test condition closer to the actual situation, and the test result has more reference value.

[0045] In some embodiments, the bearing part 12 is provided with a first limiting groove 121 for limiting the pickup device 200, and the shape of the first limiting groove 121 is adapted to the outer contour of the pickup device 200. The first limiting groove 121 provides a standardized and unique positioning reference for the installation of the pickup device 200, and the shape thereof is adapted to the outer contour of the pickup device 200, which can ensure that the spatial position, contact surface and orientation of the pickup device 200 relative to the carrier 10 and the vibrator 20 are highly consistent every time it is installed, thereby eliminating the changes in contact pressure, force angle and vibration transmission path caused by manual placement deviation, and improving the consistency and repeatability of the test.

[0046] In addition, the adaptive design of the first limiting groove 121 ensures that the pickup device 200 and the bearing part 12 have a maximum and stable contact area. Such close fit avoids the small gaps and uneven pressure that may be caused by point contact or line contact, and ensures that mechanical vibrations can be efficiently and low-lossly transmitted from the carrier 10 to the pickup device 200, further improving the accuracy of the test. The provision of the first limiting groove 121 also simplifies the installation operation, and precise positioning can be achieved without repeated adjustment, greatly shortening the clamping time of a single pickup device 200 to be tested and improving the test efficiency of the overall test process.

[0047] In some embodiments, the carrier 10 further comprises a pressing member 13 and a locking member 14 connected to the connecting seat 11, and the pressing member 13 and the locking member 14 are respectively located on opposite sides of the bearing part 12. The pressing member 13 is rotationally connected to the connecting seat 11, and the pressing member 13 has a first position state and a second position state. When the pressing member 13 is in the first position state, the pressing member 13 is spaced apart from the bearing part 12. When the pressing member 13 is in the second position state, the pressing member 13 and the bearing part 12 jointly clamp the pickup device 200. The locking member 14 is used to lock the pressing member 13 when the pressing member 13 is in the second position state.

[0048] As can be understood, since the pressing member 13 is rotationally connected to the connecting seat 11, the pressing member 13 can be switched between the first position state and the second position state. The operator can place and press the pickup device 200 to be tested by a simple rotating action, which is simple to operate and eliminates the tedious tightening steps, greatly shortens the clamping time of a single product to be tested, and significantly improves the overall test efficiency. When the pressing member 13 is rotated to the second position state and locked by the locking member 14, a stable clamping force can be applied to the pickup device 200, so that the fixing state of the pickup device 200 is stable, and the path of vibration transmission from the carrier 10 to the pickup device 200 is consistent every time the test is performed, thereby effectively reducing the random errors introduced in the installation link and providing an important mechanical guarantee for the high repeatability and consistency of the test results.

[0049] In some embodiments, as shown in Figure 3 and Figure 4 The pressing member 13 is provided with a second limiting groove 131 on the surface facing the bearing part 12, the shape of the second limiting groove 131 is adapted to the outer contour of the pickup device 200, and when the pressing member 13 is in the second position state, the first limiting groove 121 and the second limiting groove 131 jointly form a limiting cavity for limiting the pickup device 200. It can be understood that when the pressing member 13 is in the second position state, the first limiting groove 121 and the second limiting groove 131 jointly form a limiting cavity, and the pickup device 200 is wrapped in a limiting cavity that is highly consistent with its own contour, and the translational and rotational degrees of freedom of the pickup device 200 in all directions are effectively limited, ensuring that the spatial posture and position of the pickup device 200 are absolutely consistent every time it is installed, effectively reducing the test errors caused by slight positioning deviations, and further improving the repeatability of the test.

[0050] In addition, by limiting the pickup device 200 in the limiting cavity, the contact area with the pickup device 200 is increased, effectively avoiding the local stress concentration or even damage of the device caused by point contact, while ensuring that the vibration can be more efficiently and linearly transmitted to the pickup device 200 through the entire contact surface, reducing the vibration distortion caused by uneven stress, and providing a guarantee for obtaining true and accurate test data.

[0051] In some embodiments, the pressing member 13 includes a rotating part 132 rotatably connected to the connecting seat 11 and a first clamping part 133 connected to the rotating part 132, and the locking member 14 includes a connecting plate 141 connected to the connecting seat 11, a rotating frame 142 rotatably connected to the connecting plate 141, and a second clamping part 143 connected to the rotating frame 142, the second clamping part 143 is used to be clamped with the first clamping part 133 when the pressing member 13 is in the second position state.

[0052] It can be understood that when the pickup device 200 of different sizes is replaced, the position of the pressing member 13 in the second position state will change, causing the spatial position of the first clamping part 133 thereon to change, including height and horizontal angle. At this time, the rotating frame 142 and the second clamping part 143 of the locking member 14 can be freely rotated as a whole, so that they can flexibly adjust their posture and position within a certain spatial range, automatically align the changed first clamping part 133, and thus smoothly complete the clamping and locking. This self-adaptive ability reduces the tedious manual adjustment for adapting to pickup devices 200 of different sizes and models, so that the locking member 14 can adapt to different pickup devices 200, improving the applicability and flexibility of the carrier 10. Alternatively, the first clamping part 133 is a clamping hook, and the second clamping part 143 is a clamping hole, and the clamping hook is clamped in the clamping hole to achieve clamping.

[0053] In some embodiments, such as Figure 5 As shown, the vibrator 20 includes a support platform 21, a vibrating diaphragm 22 vibrating on the top surface of the support platform 21, and a vibrating block 23 connected to the vibrating diaphragm 22. The carrier 10 is connected to the vibrating block 23, and the vibrating diaphragm 22 drives the vibrating block 23 to vibrate. In this embodiment, when the vibrating diaphragm 22 is excited by an electrical signal, it mainly produces bending deformation in its own plane, thereby driving the vibrating block 23 connected to it to reciprocate up and down, thereby driving the carrier 10 to vibrate. The setting of the vibrating diaphragm 22 can effectively suppress unnecessary lateral vibration and torsional modes. For bone conduction microphone testing, this simulates the most ideal bone vibration mode perpendicular to the contact surface, significantly reducing the measurement error introduced by the impurity of the excitation signal itself, so that the measured frequency response and distortion data can more accurately reflect the performance of the microphone itself.

[0054] Furthermore, the diaphragm 22 is positioned between the support platform 21 and the vibrating block 23. On one hand, it efficiently transmits driving energy to the vibrating block 23 and the carrier 10; on the other hand, it effectively isolates the movement of the vibrating block 23 from the support platform 21 and the external environment. This prevents vibration energy from being transmitted back to the support structure, causing damage or unnecessary structural resonance. It also reduces interference from external environmental vibrations through the support platform 21 on the testing system, ensuring the stability of the testing environment. Optionally, the diaphragm 22 is positioned at the center of the top surface of the support platform 21, and the vibrating block 23 is positioned at the center of the diaphragm 22.

[0055] In some embodiments, the vibrator 20 further includes a rotating base 24 and a rotating shaft 25 rotatably connected to the rotating base 24 about a preset axis, with a support platform 21 connected to the rotating shaft 25. By rotating the rotating shaft 25, the spatial angles of the support platform 21, its carrier 10, and the pickup device 200 can be changed, allowing the testing equipment to flexibly simulate various installation postures of the pickup device 200 in actual use. For example, the vibration direction can be adjusted to vertical, horizontal, or any tilt angle to test the performance differences of the bone conduction microphone under vibration excitation in different directions, improving applicability and flexibility, while also making the test conditions more closely resemble real and complex application scenarios.

[0056] In some embodiments, the pickup device 200 and the first detection structure 40 are connected by wireless communication. The wireless communication connection realizes complete electrical isolation, and the signal is transmitted wirelessly, completely cutting off the vibration coupling and electromagnetic interference brought by the physical cable, which ensures that the first sensing signal received by the first detection structure 40 is purely generated by the vibration excitation of the carrier 10, greatly improving the measurement accuracy. And wireless connection makes it completely unnecessary to plug in and out the cable when clamping and replacing different bone conduction microphones, realizes quick replacement, the operation space is more tidy, eliminates the operation obstacles and safety hazards brought by the cable, and is especially suitable for fast and continuous batch testing on the production line.

[0057] Optionally, the pickup device 200 and the first detection structure 40 are connected through a Bluetooth adapter, which can make the test environment infinitely close to the final application scene of the product, which is beneficial to verify the performance of the bone conduction microphone integrated in the Bluetooth earphone under the actual wireless communication link, so that the test result is more relevant to the real experience of the user.

[0058] In the embodiment of the application, the first sensing signal and the second sensing signal are both electrical signals. Optionally, the second sensing signal is transmitted to an audio acquisition card, converted into a signal waveform by a processor, output to the second detection structure 50, and tested and analyzed by audio software.

[0059] Please refer to Figure 6 The embodiment also provides a test method, which is implemented by using the pickup device 200 test equipment described above, and the test method comprises the following steps:

[0060] Step S101: placing the pickup device 200 and the vibration sensor 30 on the carrier 10;

[0061] Step S102: driving the carrier 10 to vibrate by the vibrator 20;

[0062] Step S103: the pickup device 200 vibrates with the carrier 10 and generates a first sensing signal, and the vibration sensor 30 senses the vibration of the carrier 10 and generates a second sensing signal;

[0063] Step S104: The second detection structure 50 judges whether the signal strength of the second sensing signal is in a preset range; when the signal strength of the second sensing signal is in the preset range, the first detection structure 40 detects the first sensing signal.

[0064] To sum up, the test device provided in the application, the pickup device 200 vibrates with the carrier 10 and outputs a first sensing signal, the first detection structure 40 receives the first sensing signal and detects and analyzes the first sensing signal, so as to detect the performance of the pickup device 200, the test process can simulate the skull bone vibration caused by the pickup device 200 picking up the vocal cord vibration when a human speaks, so that the performance index of the pickup device 200 in normal working can be truly reflected, thereby improving the accuracy of the test; and the vibration sensor 30 is arranged to sense the vibration of the carrier 10 in real time and generate a second sensing signal, the second detection structure 50 judges whether the signal strength of the second sensing signal is in a preset range, which can effectively detect whether the working state of the vibrator 20 is normal, and ensure that the first sensing signal is detected when the vibrator 20 is in a normal working state, thereby avoiding measurement errors caused by the abnormal state of the vibrator 20, and improving the reliability of the test.
