Description

Technical Field

[0001] This invention belongs to the field of sound pickup device testing technology, and particularly relates to testing equipment and testing methods. Background Technology

[0002] Bone conduction microphones are a special type of sound pickup device that operates differently from traditional air conduction microphones. Instead of collecting air vibrations, they directly capture the vibrations of the skull bones caused by the vibrations of the vocal cords when a person speaks, converting these vibrations into electrical signals. This characteristic allows them to provide clear and reliable voice input even in harsh audio environments such as high ambient noise and strong winds, making them widely used in military communications, fire and rescue, outdoor sports headphones, and hearing aids.

[0003] Core performance metrics for bone conduction microphones, such as frequency response, harmonic distortion, and sensitivity, directly determine their speech clarity and fidelity. However, due to their unique operating principle, traditional testing methods based on acoustic cavities and reference air microphones are completely inapplicable. Some existing testing schemes utilize specially designed systems capable of simulating human skeletal vibrations; however, a significant problem with these schemes in practice is the difficulty in guaranteeing the accuracy and reliability of the test results. Due to the lack of effective monitoring of critical states during the testing process, the actual excitation conditions applied to the microphone under test by the testing system may be uncertain. This uncertainty leads to measured parameters such as frequency response and distortion failing to accurately reflect the product's performance, resulting in severely inaccurate measurements. Summary of the Invention

[0004] The purpose of this application is to provide a testing device and a testing method, aiming to solve the problem of how to improve the accuracy and reliability of testing.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a testing device is provided for detecting a pickup device. The testing device includes: a carrier for supporting the pickup device; a vibrator connected to the carrier for driving the carrier to vibrate, wherein the pickup device vibrates with the carrier and generates a first sensing signal; a vibration sensor disposed on the carrier for sensing the vibration of the carrier and generating a second sensing signal; a first detection structure communicatively connected to the pickup device for receiving the first sensing signal; and a second detection structure communicatively connected to the vibration sensor for receiving the second sensing signal and determining whether the signal strength of the second sensing signal is within a preset range; wherein, when the signal strength of the second sensing signal is within the preset range, the first detection structure detects the first sensing signal.

[0006] In some embodiments, the carrier includes a connecting seat connected to the vibrator and a support portion connected to the connecting seat. The connecting seat includes a support surface for placing the vibration sensor, and the support portion is used to support the pickup device, with the support portion and the support surface spaced apart.

[0007] In some embodiments, the support portion is provided with a first limiting groove for limiting the pickup device, the shape of the first limiting groove being adapted to the outer contour of the pickup device.

[0008] In some embodiments, the carrier further includes a pressing member and a locking member connected to the connecting seat. The pressing member and the locking member are respectively located on opposite sides of the bearing portion. The pressing member is rotatably connected to the connecting seat. The pressing member has a first position state and a second position state. When the pressing member is in the first position state, the pressing member is spaced apart from the bearing portion. When the pressing member is in the second position state, the pressing member and the bearing portion jointly clamp the pickup device. The locking member is used to lock the pressing member when it is in the second position state.

[0009] In some embodiments, the surface of the pressing member facing the bearing portion is provided with a second limiting groove, the shape of the second limiting groove being adapted to the outer contour of the pickup device. When the pressing member is in the second position state, the first limiting groove and the second limiting groove together form a limiting cavity for limiting the pickup device.

[0010] In some embodiments, the pressing member includes a rotating portion rotatably connected to the connecting seat and a first latching portion connected to the rotating portion, and the locking member includes a connecting plate connected to the connecting seat, a rotating frame rotatably connected to the connecting plate, and a second latching portion connected to the rotating frame, wherein the second latching portion is used to engage with the first latching portion when the pressing member is in the second position state.

[0011] In some embodiments, the vibrator includes a support platform, a vibrating diaphragm disposed on the top surface of the support platform, and a vibrating block connected to the vibrating diaphragm. The carrier is connected to the vibrating block, and the vibrating diaphragm is used to drive the vibrating block to vibrate.

[0012] In some embodiments, the vibrator further includes a rotating base and a rotating shaft rotatably connected to the rotating base about a preset axis, and the support platform is connected to the rotating shaft.

[0013] In some embodiments, the pickup device and the first detection structure are connected by wireless communication.

[0014] Secondly, a testing method is provided, implemented using the aforementioned testing equipment, comprising the following steps: Place the sound pickup device and vibration sensor on the vehicle; The vehicle is driven to vibrate by a vibrator; The pickup device vibrates with the vehicle and generates a first sensing signal, and the vibration sensor senses the vibration of the vehicle and generates a second sensing signal; The second detection structure determines whether the signal strength of the second sensing signal is within a preset range; when the signal strength of the second sensing signal is within the preset range, the first detection structure detects the first sensing signal. The testing equipment provided in this application includes a sound pickup device that vibrates with the vehicle and outputs a first sensing signal. A first detection structure receives and analyzes the first sensing signal to detect the performance of the sound pickup device. This testing process can simulate the vibration of the skull bones caused by the vibration of the vocal cords when a person speaks, thus allowing the performance indicators of the sound pickup device under normal working conditions to be truly reflected, thereby improving the accuracy of the test. Furthermore, by setting a vibration sensor to sense the vibration of the vehicle in real time and generate a second sensing signal, the second detection structure determines whether the signal strength of the second sensing signal is within a preset range, which can effectively detect whether the working state of the vibrator is normal. The first sensing signal is only detected when the vibrator is in a normal working state, thereby avoiding measurement errors caused by abnormal vibrator conditions and improving the reliability of the test.

[0022] Please see Figure 1 and Figure 2 This application provides a testing device for detecting a microphone 200. The testing device includes: a carrier 10 for carrying the microphone 200; a vibrator 20 connected to the carrier 10 for driving the carrier 10 to vibrate, wherein the microphone 200 vibrates with the carrier 10 and generates a first sensing signal; a vibration sensor 30 disposed on the carrier 10 for sensing the vibration of the carrier 10 and generating a second sensing signal; a first detection structure 40 communicatively connected to the microphone 200 for receiving the first sensing signal; and a second detection structure 50 communicatively connected to the vibration sensor 30 for receiving the second sensing signal and determining whether the signal strength of the second sensing signal is within a preset range; wherein, when the signal strength of the second sensing signal is within the preset range, the first detection structure 40 detects the first sensing signal.

[0023] It should be noted that the sound pickup device 200 in this embodiment is a bone conduction microphone. A bone conduction microphone picks up sound by collecting vibrations from the human skeleton, such as the skull, rather than from air vibrations as traditional microphones do. When wearing a bone conduction microphone, the user's vocal cord vibrations are directly transmitted to the skull through tissues such as the throat and jaw, causing skull vibrations. Sensors such as piezoelectric ceramics or accelerometers within the bone conduction microphone are in close contact with the skin, directly detecting these minute bone vibrations and converting them into electrical signals. Of course, in other possible implementations, the sound pickup device 200 could also be any other microphone that picks up sound by sensing vibrations.

[0024] In this embodiment, 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 it, thereby detecting the performance of the pickup device 200, such as frequency response, distortion, and sensitivity. This test process can simulate the vibration of the skull caused by the vibration of the vocal cords when the pickup device 200 picks up human speech, so that the performance indicators of the pickup device 200 during normal operation can be truly reflected, thereby improving the accuracy of the test.

[0025] In this embodiment, the first detection structure 40 has the function of analyzing the first sensed signal generated after the pickup device 200 senses vibration. According to a preset data processing logic, the acoustic performance test results of the pickup device 200 can be obtained, such as acoustic performance parameters like frequency response, total harmonic distortion, and sensitivity. The first detection structure 40 can be any available electronic device with computing capabilities, such as any type of audio analysis instrument and computer. Optionally, the second detection structure 50 can also be an electronic device with computing capabilities, such as any type of audio analysis instrument and computer.

[0026] Understandably, this application also includes a control system. The vibrator 20, vibration sensor 30, first detection structure 40 and second detection structure 50 are all communicatively connected to the control system. The control system can control the vibrator 20, vibration sensor 30, first detection structure 40 and second detection structure 50 to automatically coordinate and operate.

[0027] In this embodiment, the second detection structure 50 can quickly diagnose whether the vibrator 20 is malfunctioning by determining whether the signal strength of the second sensing signal is within a preset range. This is because when the vibrator 20 malfunctions, such as failing or becoming loose, the signal strength of the second sensing signal will be too high or too low. Therefore, this malfunction can be clearly distinguished from a fault in the pickup device 200. This allows operators to quickly locate the source of the problem, avoiding tedious cross-checking between the testing equipment and the product under test, greatly shortening the fault diagnosis time, improving the efficiency of the production quality inspection process, and reducing equipment maintenance costs. Optionally, the second sensing signal is an electrical signal. Optionally, the preset range is 90mV~110mV.

[0028] Understandably, the vibration sensor 30 provides data support for equipment condition monitoring by detecting parameters such as displacement, velocity, and acceleration of the vibrating body. Optionally, the vibration sensor 30 can be an acceleration sensor, velocity sensor, or displacement sensor, etc.

[0029] The testing equipment provided in this application includes a microphone 200 that vibrates with the carrier 10 and outputs a first sensing signal. A first detection structure 40 receives and analyzes the first sensing signal, thereby detecting the performance of the microphone 200. This testing process can simulate the vibration of the skull caused by the vibration of the vocal cords when a person speaks, thus allowing the performance indicators of the microphone 200 during normal operation to be accurately reflected, thereby improving the accuracy of the test. Furthermore, by setting a vibration sensor 30 to sense the vibration of the carrier 10 in real time and generate a second sensing signal, and a second detection structure 50 to determine whether the signal strength of the second sensing signal is within a preset range, the device can effectively detect whether the working state of the vibrator 20 is normal. The first sensing signal is only detected when the vibrator 20 is in a normal working state, thereby avoiding measurement errors caused by abnormal state of the vibrator 20 and improving the reliability of the test.

[0030] In some embodiments, such as Figure 3 and Figure 4 As shown, the carrier 10 includes a connecting seat 11 connected to the vibrator 20 and a support portion 12 connected to the connecting seat 11. The connecting seat 11 includes a support surface (not shown) for placing the vibration sensor 30. The support portion 12 is used to support the pickup device 200 and is spaced apart from the support surface.

[0031] Optionally, the carrier 10 also includes a support block 15 connected to the support surface. The support block 15 supports the bearing portion 12 to a preset height, so that the bearing portion 12 is spaced apart from the support surface. By setting 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, thus making the vibration sensor 30 as close as possible to the drive point of the vibrator 20. This allows for the most direct and non-destructive monitoring of the original mechanical excitation input to the vibrator 20, which is beneficial for detecting the working state of the vibrator 20. Furthermore, by spaced the bearing portion 12 for supporting the pickup device 200 from the support surface, mechanical interference from the installation of the pickup device 200 and its own mass on the monitoring area of ​​the vibration sensor 30 is effectively avoided. This ensures that the second sensing signal can purely reflect the "input excitation" without being affected by the pickup device 200 under test, thereby providing an exceptionally stable and reliable reference signal for the entire testing system.

[0032] In addition, the spaced support surfaces of the bearing part 12 and the connecting seat 11 actually form a specific vibration transmission path. The mechanical characteristics of this path can be precisely designed and controlled, thereby better simulating the vibration transmission characteristics of the bone conduction microphone in the real use environment, such as coupling with the skull through the skin, soft tissue, etc. This makes the test conditions closer to reality and the test results more valuable for reference.

[0033] In some embodiments, the carrier 12 is provided with a first limiting groove 121 for limiting the pickup device 200. 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. Its shape 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 each time it is installed. This can eliminate the changes in contact pressure, force angle and vibration transmission path caused by manual placement deviation, thereby improving the consistency and repeatability of the test.

[0034] Furthermore, the adaptability design of the first limiting groove 121 ensures a maximum and stable contact area between the pickup device 200 and the carrier 12. This tight fit avoids the minute gaps and uneven pressure that may occur with point or line contact, ensuring that mechanical vibration can be efficiently and with low loss transmitted from the carrier 10 to the pickup device 200, further improving the accuracy of the test. The setting of the first limiting groove 121 also simplifies the installation operation, achieving precise positioning without repeated adjustments, significantly shortening the clamping time of a single pickup device 200 under test, and improving the overall testing efficiency.

[0035] In some embodiments, the carrier 10 further includes a pressing member 13 and a locking member 14 connected to the connecting seat 11. The pressing member 13 and the locking member 14 are respectively located on opposite sides of the bearing portion 12. The pressing member 13 is rotatably connected to the connecting seat 11. 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 and the bearing portion 12 are spaced apart. When the pressing member 13 is in the second position state, the pressing member 13 and the bearing portion 12 jointly clamp the pickup device 200. The locking member 14 is used to lock the pressing member 13 when it is in the second position state.

[0036] Understandably, since the pressing component 13 is rotatably connected to the connecting seat 11, the pressing component 13 can switch between a first position and a second position. Operators can easily place and clamp the microphone 200 under test through a simple rotational action. This simple operation eliminates tedious tightening steps, significantly shortens the clamping time for a single product under test, and substantially improves overall testing efficiency. When the pressing component 13 rotates to the second position and is locked by the locking component 14, it applies a stable clamping force to the microphone 200, ensuring a stable fixed state for the microphone 200. This guarantees that the path of vibration transmitted from the carrier 10 to the microphone 200 remains consistent during each test, effectively reducing random errors introduced during installation and providing crucial mechanical assurance for high repeatability and consistency of test results.

[0037] In some embodiments, such as Figure 3 and Figure 4 As shown, the surface of the pressing member 13 facing the bearing portion 12 is provided with a second limiting groove 131. The shape of the second limiting groove 131 is adapted to the outer contour of the pickup device 200. When the pressing member 13 is in the second position state, the first limiting groove 121 and the second limiting groove 131 together 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 together form a limiting cavity, and the pickup device 200 is wrapped in a limiting cavity that fits its own shape perfectly. The translational and rotational degrees of freedom of the pickup device 200 in all directions are effectively restricted, ensuring that the spatial attitude and position of the pickup device 200 are absolutely consistent each time it is installed. This effectively reduces the test error caused by small positioning deviations and further improves the repeatability of the test.

[0038] In addition, by limiting the pickup device 200 through the limiting cavity, the contact area with the pickup device 200 is increased, which effectively avoids the local stress concentration or even damage to the device that may be caused by point contact. At the same time, it ensures that the vibration can be transmitted to the pickup device 200 more efficiently and linearly through the entire contact surface, reducing vibration distortion caused by uneven force, and providing a guarantee for obtaining real and accurate test data.

[0039] In some embodiments, the pressing member 13 includes a rotating part 132 rotatably connected to the connecting seat 11 and a first latching part 133 connected to the rotating part 132. 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 latching part 143 connected to the rotating frame 142. The second latching part 143 is used to engage with the first latching part 133 when the pressing member 13 is in a second position state.

[0040] Understandably, when a pickup device 200 of different sizes is replaced, the position of the pressing part 13 in the second position will change accordingly, causing the spatial position of the first latching part 133 on it to change, including its height and horizontal angle. At this time, the rotating frame 142 and the second latching part 143 of the locking part 14 can rotate freely as a whole, allowing it to flexibly adjust its posture and position within a certain spatial range, automatically aligning with the changed first latching part 133, thereby successfully completing the locking. This adaptive capability reduces the tedious manual adjustments required to adapt to pickup devices 200 of different sizes and models, enabling the locking part 14 to adapt to different pickup devices 200, improving the applicability and flexibility of the carrier 10. Optionally, the first latching part 133 is a hook, and the second latching part 143 is a hole, with the hook engaging with the hole to achieve locking.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] In some embodiments, the pickup device 200 and the first detection structure 40 are connected wirelessly. This wireless connection provides complete electrical isolation, transmitting signals wirelessly and completely eliminating vibration coupling and electromagnetic interference caused by physical cables. This ensures that the first induction signal received by the first detection structure 40 is purely generated by the vibration excitation of the carrier 10, greatly improving measurement accuracy. Furthermore, the wireless connection eliminates the need to plug and unplug cables when mounting or changing different bone conduction microphones, enabling rapid setup, a cleaner operating space, and eliminating operational obstacles and safety hazards caused by cables. This makes it particularly suitable for rapid, continuous batch testing on production lines.

[0045] Optionally, the pickup device 200 and the first detection structure 40 are connected via a Bluetooth adapter, which can make the test environment infinitely close to the final application scenario of the product. This is beneficial for verifying the performance of the bone conduction microphone integrated into the Bluetooth headset under actual wireless communication links, making the test results more relevant to the user's real experience.

[0046] In this embodiment, both the first sensing signal and the second sensing signal are 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.

[0047] Please see Figure 6 This embodiment also provides a testing method, implemented using the aforementioned pickup device 200 testing equipment. The testing method includes: Step S101: Place the pickup device 200 and the vibration sensor 30 on the carrier 10; Step S102: Drive the vehicle 10 to vibrate via the vibrator 20; Step S103: The pickup device 200 vibrates with the vehicle 10 and generates a first sensing signal, and the vibration sensor 30 senses the vibration of the vehicle 10 and generates a second sensing signal; Step S104: The second detection structure 50 determines whether the signal strength of the second sensing signal is within a preset range; when the signal strength of the second sensing signal is within the preset range, the first detection structure 40 detects the first sensing signal.

[0048] In summary, the testing equipment provided in this application allows the pickup device 200 to vibrate with the carrier 10 and output a first sensing signal. The first detection structure 40 receives and analyzes the first sensing signal, thereby enabling the detection of the performance of the pickup device 200. This testing process can simulate the vibration of the skull bones caused by the vibration of the vocal cords when a person speaks, thus allowing the performance indicators of the pickup device 200 during normal operation to be truly reflected, thereby improving the accuracy of the test. Furthermore, by setting a vibration sensor 30 to sense the vibration of the carrier 10 in real time and generate a second sensing signal, and the second detection structure 50 to determine whether the signal strength of the second sensing signal is within a preset range, the working state of the vibrator 20 can be effectively detected. The first sensing signal is only detected when the vibrator 20 is in a normal working state, thereby avoiding measurement errors caused by abnormal state of the vibrator 20 and improving the reliability of the test.

[0049] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
