Description

Technical Field

[0001] The present invention relates to the technical field of hearing aids, and in particular to a production and testing method and device for hearing aids, and a hearing aid. Background Art

[0002] As a high-precision portable medical device, hearing aids have core functions including sound acquisition, signal processing, and amplified output, requiring the implementation of complex functions within a miniaturized design. Hearing aids rely on a variety of sensors to achieve their core functions, including microphones for sound acquisition and directional positioning, environmental sensors for optimizing sound processing algorithms, motion sensors for dynamic volume adjustment, and health monitoring sensors (such as heart rate and temperature sensors) for expanded functionality. Furthermore, sensors support feedback suppression, noise reduction, and user interaction, enabling hearing aids to enhance the listening experience while gradually evolving towards intelligence and health management.

[0003] Because specialty hearing aids typically rely on small-capacity batteries, battery life is a crucial factor in user experience. However, specialty hearing aids are highly sensitive to energy consumption. Excessive energy consumption significantly impacts device battery life, potentially failing to meet user demands for all-day wear. Therefore, in-depth analysis and optimization of hearing aid energy consumption sources are crucial for improving product performance.

[0004] Functional testing is the core function of the device, including the sound collection performance of the microphone, the noise reduction and echo suppression capabilities of the signal processor, the signal output characteristics of the amplifier, and the sound playback quality of the speaker. The purpose of functional testing is to ensure that the hearing aid can achieve its designed functions under specific operating modes. Energy consumption testing measures the total power consumption of the hearing aid under different operating conditions to verify whether it is within the design target range.

[0005] The design and configuration of a hearing aid determine its energy consumption performance. For example, insufficiently optimized circuit design, ineffectively controlled static power consumption in standby mode, or inefficient power management modules can significantly increase overall energy consumption. Furthermore, hearing aids are manufactured using surface mount technology (SMT), and the quality of its process directly impacts the product's energy performance. For example, soldering defects in the SMT process can cause abnormally increased circuit impedance, thereby increasing current loss. Residual solder after soldering can trigger parasitic circuits, leading to unnecessary current consumption.

[0006] In the hearing aid testing process, functional testing and energy consumption testing are often performed as separate steps. This independent testing model has its advantages, but lacks correlation analysis between the two. If the functional test passes but the energy consumption exceeds the standard, traditional testing processes cannot quickly identify the root cause of the problem. Especially in complex, specialized hearing aid products, high energy consumption may be due to multiple factors, not just the design of the functional module itself. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0043] The following combination Figures 1-4 The present invention describes a hearing aid production testing method, device and hearing aid.

[0044] The hearing aid of the present invention includes a printed circuit board and various functional components integrated on the printed circuit board. The functional components include a microphone, a signal processor, an amplifier, and a receiver. The hearing aid of the present invention uses a printed circuit board (PCBA) as its core hardware carrier and integrates the following key functional components, each of which performs a different core function of the hearing aid and jointly achieves the purpose of hearing enhancement:

[0045] The pickup, or microphone, is responsible for collecting sound waves in the external environment and converting them into electrical signals. It is the starting point of the hearing aid's sound processing.

[0046] The microphone can be a single or multiple highly sensitive microphones, capturing the frequency, intensity, and directionality of sound. A multi-microphone array enhances directionality and suppresses ambient noise, improving speech clarity. The microphone can also be equipped with wind noise reduction features to adapt to complex listening environments.

[0047] The signal processor digitizes the electrical signals collected by the microphone and executes various sound optimization algorithms, such as noise reduction, feedback suppression, gain adjustment, and speech enhancement. The signal processor includes a high-speed digital signal processing unit (DSP) for real-time audio processing and supports a variety of algorithms, such as frequency segmentation, dynamic range compression (DRC), and directionality optimization. This allows for programmable adjustments to the hearing aid's output to accommodate varying hearing loss patterns.

[0048] The amplifier amplifies the weak signal output by the signal processor, ensuring that the signal strength is sufficient to drive the receiver while maintaining signal clarity. The amplifier includes a low-noise amplifier (LNA) and a power amplifier (PA), which are used for primary signal amplification and output signal driving, respectively.

[0049] The receiver, also known as the speaker, can convert the amplified electrical signal into sound waves and transmit them directly to the user's ear canal to reproduce the sound.

[0050] Receivers typically use miniature dynamic or piezoelectric speakers, which offer high performance and a compact size. They offer a wide frequency response, meeting the frequency perception needs of users with varying hearing loss. Receiver design emphasizes clarity and comfort, avoiding harshness or distortion.

[0051] The printed circuit board (PCB) serves as a carrier to integrate the above functional components and achieves efficient electrical connections between the functional components through precise wiring. This allows the hearing aid's PCBA to be compact, meeting the requirements of lightweight and miniaturized hearing aids.

[0052] The embodiments of the present invention highly integrate the microphone, signal processor, amplifier and receiver on a printed circuit board to form a compact and efficient functional architecture, which can collect, process and amplify sound signals with high quality and provide users with a clear and natural listening experience. It adapts to the trend of miniaturization, intelligence and low energy consumption of hearing aids and meets the needs of users with different degrees of hearing loss.

[0053] The hearing aid production testing method of the present invention mainly includes step 110 , step 120 , step 130 , step 140 and step 150 .

[0054] Step 110 : Detect at least one of the current and the voltage of each functional component in the printed circuit board of the hearing aid to be tested under the target detection configuration.

[0055] The test configuration is used to simulate the operating mode of a hearing aid. The target test configuration is a test environment designed to simulate the actual operating mode of a hearing aid. In this configuration, the hearing aid's various functional components are in operation, and their performance and energy consumption are analyzed by measuring current and voltage.

[0056] In the target detection configuration, each functional component on the hearing aid printed circuit board is tested by setting a specific operating mode (such as simulating actual usage). Current or voltage (or both) can be measured to evaluate whether each functional component is operating as expected. The target detection configuration simulates typical hearing aid usage scenarios and can include factors such as different volume settings and ambient noise levels to ensure that the performance of the functional components under different conditions can be fully evaluated.

[0057] It's understandable that you can begin by testing the power supply on and off on the printed circuit board (PCB). The PCBA can be placed in a jig area, and the prongs on the jig can be used to contact the test points on the PCBA. The test points on the PCBA can be connected to the DAC and ADC pins of the microcontroller unit (MCU) on the test equipment. The DAC pin outputs a voltage, which is then read from the ADC pin at the other end of the capacitor. This entire process takes 10 milliseconds. If the ADC voltage is not equal to the DAC voltage, and a voltage fluctuation is detected when the DAC is turned on, it can be determined that the capacitor is electrically correct, meaning that the voltage rails across the capacitor are correct.

[0058] Next, before controlling the MOS transistor to power the hearing aid PCBA, the voltage across a designated capacitor is detected. The high-voltage side of this capacitor is connected to the MCU's ADC pin. Due to the operation of the hearing aid's internal boost circuit, the voltage on this capacitor can reach between 1.8V and 2.0V. If the voltage is correct, the boost circuit in the hearing aid is functioning properly. If the MCU is connected to the hearing aid PCBA's communication pin, it controls the fixture's buzzer to sound or mute. By communicating with the hearing aid, the pickup's response value is read. If the value is within the empirical range, the hearing aid's pickup is functioning properly.

[0059] The hearing aid receiver can also be controlled through the communication line to emit pure tones with fixed frequencies of 500 Hz and 1000 Hz in turn. The pure tones emitted by the receiver are collected by the microphone, and the MCU analyzes whether the received pure tone frequency is normal, thereby determining whether the receiver is functioning normally.

[0060] You can also implant a preset program into the hearing aid through the communication line, and then the buzzer emits a specific pure tone. At this time, check the current of the PCBA power supply circuit. This current is sampled by the sampling resistor and sent to the ADC pin of the device's MCU to obtain the total energy consumption, and determine whether the total energy consumption meets the design requirements.

[0061] Step 120 : When the total power consumption of the printed circuit board under the target detection configuration meets a preset power consumption condition, the current and voltage of each functional component are respectively obtained.

[0062] During the total energy consumption test, the overall energy consumption of the hearing aid is ensured to meet predetermined standards. By measuring the current and voltage of each functional component, it is possible to confirm whether the energy consumption of each functional component is within a reasonable range. If the total energy consumption exceeds the predetermined threshold, it may indicate that the energy consumption of a functional component is abnormal and requires further analysis and testing.

[0063] In this embodiment, the overall energy consumption of the hearing aid can be ensured to meet the design requirements, avoiding battery life problems caused by excessive energy consumption. By separately obtaining the current and voltage of each functional component, the components with large energy consumption can be identified one by one, providing data support for subsequent problem location.

[0064] Step 130 : determining a function test result and an energy consumption test result of each functional component based on at least one of the current and the voltage of each functional component.

[0065] The energy consumption test results refer to the energy consumption information calculated by measuring the current and voltage of the hearing aid's functional components. This data helps analyze the energy efficiency and battery life of the hearing aid.

[0066] Based on the current and voltage data of each functional device, the operating status and energy consumption of each functional device are evaluated. By analyzing the current and voltage signals, it is possible to determine whether the functional device is operating properly and, combined with the energy consumption data, to assess whether it meets the predetermined energy efficiency requirements.

[0067] Step 140 : When the energy consumption detection result of at least one functional component is abnormal, a verification detection configuration for verifying the abnormal result is determined based on the abnormal functional component and the function detection result of the abnormal functional component.

[0068] Verification test configurations simulate different operating modes than target test configurations. Verification test configurations are specialized test configurations designed to verify anomaly detection results, distinct from target test configurations. Verification configurations can further confirm that functional device performance and energy consumption meet requirements by adjusting operating modes, power settings, or other operating conditions.

[0069] When abnormal energy consumption is detected for a functional device, a verification test configuration can be set up based on the device's functional test results (e.g., abnormal operating status). This configuration differs from the target configuration, and operating conditions can be modified, such as varying volume, frequency, or noise processing levels, to further confirm whether the abnormality is caused by a performance issue with the device itself or a change in external conditions.

[0070] It's understandable that through review and verification, it's possible to more clearly determine whether abnormal energy consumption is caused by design flaws, process issues, or other external factors, effectively identifying the root cause of the problem. Furthermore, the introduction of verification configurations can avoid errors in single test results, ensuring the reliability of detection.

[0071] Step 150 : re-test at least one of the current and voltage of the functional device with abnormal energy consumption in the previous test under the verification configuration to determine the energy consumption test result of the hearing aid to be tested.

[0072] Retest functional devices that showed abnormal energy consumption in the previous test under the verification configuration, and obtain more accurate energy consumption data by measuring current and voltage again.

[0073] In some embodiments, the energy consumption curve of the previous test can be compared to determine whether the energy consumption change in this test is related to the configuration change, and to confirm whether there is a design or process problem.

[0074] It's understandable that verification testing can help confirm the exact cause of energy consumption anomalies from previous testing, ensuring the accuracy and reliability of test results. If verification results are closely related to configuration changes, further design or production process optimization can be used to avoid similar issues.

[0075] It's understandable that by establishing a connection between functional testing and energy consumption testing, these two steps are no longer independent, but rather interdependent and complementary. By continuously comparing energy consumption data under the target configuration and the verification configuration during the testing process, it can help distinguish whether energy consumption anomalies are caused by design issues, configuration issues, or other external factors. If energy consumption anomalies are related to configuration changes, it can quickly help determine whether they are design flaws or improper configuration in certain specific operating modes.

[0076] High energy consumption can stem from a variety of factors. Traditional detection methods may only detect anomalies at a specific level and fail to fully analyze the causes of energy consumption changes. However, this method, by reconfiguring the verification model and analyzing energy consumption changes, can more clearly identify the design or process links that cause energy consumption anomalies, providing data support for optimizing designs and improving production processes.

[0077] It is understood that by reviewing energy consumption data under different configurations in this embodiment, not only can potential design issues be identified during testing, but also possible process defects can be promptly detected during production. For example, soldering issues during the SMT process or improper wiring in the circuit board design can lead to abnormal energy consumption. Through review testing, these issues can be prevented from being overlooked during mass production, thereby improving product quality.

[0078] The hearing aid production testing method provided by an embodiment of the present invention, by separately testing the voltage and current data of each functional component and combining functional testing with energy consumption testing, can more accurately locate the root cause of problems and improve testing efficiency and accuracy. In particular, in complex hearing aid products, by setting a verification test configuration to review the product, it helps to discover energy consumption anomalies caused by various factors and provides strong support for design optimization and process improvement.

[0079] In some embodiments, the detection configuration includes at least one of a power supply voltage to the printed circuit board, audio parameters processed by the microphone and receiver, and processing parameters of the signal processor and amplifier.

[0080] The power supply voltage to the printed circuit board refers to the voltage supplied to the printed circuit board, which affects the working state and energy consumption of the entire hearing aid.

[0081] Audio parameters include the frequency, amplitude, and other characteristics of the audio signals processed by the microphone and receiver. Identifying these audio parameters helps verify whether the sound signal is transmitted and processed as expected and obtains expected energy consumption data.

[0082] The processing parameters of signal processors and amplifiers refer to the key operating parameters of signal processors and amplifiers when they are working, such as whether the signal processor has noise reduction turned on, the signal-to-noise ratio of the processed data, and the amplification factor of the amplifier. These parameters ensure that they can process audio signals according to design requirements and provide appropriate amplification effects.

[0083] Based on the abnormal functional device and the functional test results of the abnormal functional device, determining the verification configuration for reviewing the abnormal result includes: based on the abnormal functional device, determining the verification configuration item for reviewing the abnormal result corresponding to the abnormal functional device from the test configuration; based on the abnormal functional device and the functional test results of the abnormal functional device, adjusting the parameters in the verification configuration item for reviewing the abnormal result to obtain the verification test configuration.

[0084] When abnormal energy consumption is found in certain functional components such as microphones and amplifiers during the detection process, the verification configuration can be determined based on the abnormal functional components and their functional test results.

[0085] First, find the configuration items related to the abnormal functional device in the test configuration. These configuration items will help further verify the cause of the abnormality. Based on the abnormal functional device and its test results, adjust the relevant parameters in the verification configuration.

[0086] It is understandable that by adjusting these parameters, the verification configuration can be made more adaptable to the needs of troubleshooting anomalies so as to locate the problem more accurately. The verification configuration can perform more in-depth detection on functional devices where anomalies are found, ensuring that the problem can be accurately identified and resolved in subsequent steps.

[0087] In some embodiments, re-detecting at least one of the current and voltage of a functional device with abnormal energy consumption in a previous detection under a verification configuration to determine an energy consumption detection result of the hearing aid to be tested includes steps 210 and 220 .

[0088] Step 210 , under the verification configuration, re-detecting the current and / or voltage of the functional device with abnormal energy consumption to generate a verification energy consumption curve;

[0089] Step 220 : extracting energy consumption features from the verification energy consumption curve and the energy consumption curve of the previous detection, respectively, and determining whether the energy consumption change is correlated with the change of the verification configuration based on the energy consumption features.

[0090] Under the verification configuration, retest the current and / or voltage of functional devices that exhibited abnormal energy consumption during the previous test, and generate a verification energy consumption curve. The verification configuration can refer to an operating mode or parameter setting that differs from the initial test. It is used to troubleshoot potential issues that could not be discovered under the target configuration.

[0091] Adjustments to the verification configuration may include changing the frequency of the audio signal, changing the power supply voltage, or modifying other processing parameters to simulate different operating environments or conditions.

[0092] The validation energy consumption curve is a graph based on retested data that shows the current and voltage changes of a functional device under specific operating conditions.

[0093] Suppose that during initial testing, the hearing aid amplifier is found to have abnormal energy consumption. First, the amplifier's current and voltage can be retested in the verification configuration. If the input signal in the configuration is adjusted, such as by changing the amplification parameters, this will affect the amplifier's operating state, thus generating a new verification energy consumption curve.

[0094] Energy consumption features are extracted from the verification energy consumption curve and the energy consumption curve of the previous detection, and the difference between the two is analyzed to confirm whether the energy consumption change is associated with the change of the verification configuration.

[0095] Energy consumption characteristics may include key data characteristics such as total energy consumption, energy consumption fluctuations at specific frequencies, and different current and voltage change rates.

[0096] By comparing and verifying the energy consumption curve with the energy consumption curve of the previous test, you can analyze whether the configuration change has affected energy consumption, and then determine whether the configuration adjustment can help locate and resolve energy consumption anomalies.

[0097] In the previous detection, the energy consumption curve of the receiver shows an abnormally high energy consumption fluctuation. After adjusting the verification configuration, for example, increasing the input signal frequency, it may cause the working state of the receiver to change, thereby changing its energy consumption characteristics. At this time, by comparing the energy consumption curves of the two detections, it may be found that the energy consumption of the receiver at different frequencies is very different. At this time, by analyzing these features, confirming that the energy consumption change is related to the change of the verification configuration, it can further analyze the reason for the high energy consumption, which may be due to design problems or improper configuration.

[0098] It can be understood that by re-detecting and generating verification energy consumption curves, and extracting energy consumption features and analyzing relevance, the energy consumption performance of each functional device of the hearing aid in different working modes can be better understood, which helps to identify the root cause of abnormal energy consumption, thereby improving the accuracy of detection and optimizing the design and performance of the hearing aid.

[0099] In some embodiments, in the case where the functional device with abnormal energy consumption detection results is a signal processor or an amplifier, adjusting the parameters in the verification configuration item for reviewing abnormal results to obtain a verification detection configuration includes: adjusting the signal-to-noise ratio in the processing parameters of the signal processor or the amplification parameter in the processing parameters of the amplifier in the verification configuration item for reviewing abnormal results to obtain a verification detection configuration.

[0100] During the detection process, if the energy consumption of the signal processor or the amplifier is found to be abnormal, i.e., their current, voltage and energy consumption values do not meet expectations, it indicates that their working state may have problems.

[0101] In order to solve the problem of abnormal energy consumption, the working conditions of these devices under different conditions can be compared and verified by adjusting the parameters in the verification configuration.

[0102] The signal-to-noise ratio of the signal processor is a measure of the ratio between signal quality and noise when the signal processor receives an audio signal. The higher the signal-to-noise ratio, the clearer the signal and the less the noise. By adjusting the signal-to-noise ratio parameter, different working environments can be simulated to see if the energy consumption performance of the signal processor changes under different signal-to-noise ratios.

[0103] If the energy consumption abnormality is related to the setting of the signal-to-noise ratio, it may indicate that the signal processor is not efficient when processing certain signals, resulting in additional energy consumption, so it may be a design or configuration problem. However, if the energy consumption is larger after the signal-to-noise ratio changes, but the difference from the previous detection result is not large, it indicates that there may be no problem in the design, but only related to the quality of the manufacturing process.

[0104] For amplifiers, the amplification parameters (such as gain or gain) within their processing parameters directly affect the degree to which the amplifier amplifies the input signal. Excessively high amplifier gain can lead to over-amplification of the signal, increasing energy consumption. Therefore, adjusting the amplification parameter settings (such as reducing the gain) can help determine whether the amplifier's settings are too aggressive, leading to abnormal energy consumption.

[0105] It is understood that by adjusting the above parameters, a new verification test configuration can be formed. The new configuration settings will be used to re-test the energy consumption of the signal processor or amplifier under the new parameters, thereby helping to determine whether there are design issues or improper configurations that cause abnormal energy consumption.

[0106] Suppose, during initial testing, the amplifier's energy consumption is abnormally high. This could be due to excessive gain. In this case, adjust the amplifier gain in the verification configuration to reduce the gain value and retest the amplifier's energy consumption. If the energy consumption returns to normal after retesting, it can be inferred that the abnormal energy consumption is caused by the excessively high gain setting.

[0107] In other words, when a signal processor or amplifier experiences abnormal energy consumption, adjusting processing parameters such as the signal-to-noise ratio (signal processor) or amplification gain (amplifier) ​​to form a new verification configuration and retesting its energy consumption can help confirm whether the high energy consumption problem is caused by the settings of these parameters.

[0108] In some embodiments, when the functional device with an abnormal energy consumption detection result is a microphone or a receiver, the parameters in the verification configuration item used to review the abnormal result are adjusted to obtain a verification detection configuration, including: adjusting the power supply voltage to the printed circuit board in the verification configuration item used to review the abnormal result, and adjusting the frequency and amplitude in the audio parameters processed by the microphone or receiver to obtain the verification detection configuration.

[0109] If abnormal energy consumption is detected in the microphone or receiver during testing, it indicates that their energy consumption is not as expected. This may be due to a design issue with the device itself or an inappropriate operating environment. Therefore, it is necessary to adjust certain operating parameters to verify and determine the root cause of the abnormal energy consumption.

[0110] Supply voltage is a key factor affecting the operating state of a microphone or receiver. If the supply voltage is too high or too low, it can cause the device to consume excessive energy, resulting in abnormal power consumption. Therefore, adjusting the supply voltage on the printed circuit board can help simulate device performance under different voltage conditions and verify whether voltage instability is causing abnormal power consumption.

[0111] The main function of microphones and receivers is to process audio signals. The frequency and amplitude of the audio directly affect their energy consumption.

[0112] Different frequencies require the microphone or receiver to respond differently to the signal. If the frequency is set too high or too low, the device may process the signal inefficiently, consuming more power.

[0113] The amplitude of an audio signal determines its strength. A larger amplitude may require more power to process the signal, leading to increased energy consumption.

[0114] It is understandable that by adjusting these audio parameters, it is possible to verify whether the abnormal energy consumption performance is caused by unreasonable settings of frequency and amplitude.

[0115] In this embodiment, by adjusting the above parameters such as the supply voltage, frequency, amplitude, etc., a new verification detection configuration can be generated, and the working condition of the microphone or receiver can be re-detected based on the configuration, thereby determining the root cause of the abnormal energy consumption, whether it is due to improper voltage, audio parameter configuration problems, or other factors that lead to increased energy consumption.

[0116] Suppose that during initial testing, a microphone pickup's energy consumption is found to be abnormally high. Possible causes include: the microphone pickup's operating voltage is too high, causing it to consume excessive power; or the processed audio frequency or amplitude is too high, causing the device to require more energy to process the audio signal.

[0117] To verify these reasons, you can adjust the following parameters: You can adjust the supply voltage to simulate the changes in the pickup's energy consumption under different voltage conditions; you can also adjust the frequency and amplitude of the audio signal to check how the energy consumption changes under these changes.

[0118] It is understandable that through these adjustments, it is possible to verify whether the abnormal energy consumption of the pickup is caused by the unreasonable setting of these parameters, thereby further locating the problem and optimizing the design or configuration.

[0119] When an abnormality is found in the microphone or receiver during energy consumption testing, the performance of these functional components under different working conditions can be simulated by adjusting parameters such as the power supply voltage, frequency, and amplitude in the verification configuration items, providing strong support for troubleshooting and resolving high energy consumption issues.

[0120] In some embodiments, the printed circuit board also includes a memory, and the hearing aid production inspection method of the embodiment of the present invention further includes: writing data to different areas of the memory, reading data at different addresses after powering off and powering on the printed circuit board, and comparing the data with the written data.

[0121] In hearing aids, memory, such as EEPROM, is used to store key configuration information or device status data. The data in the memory needs to remain consistent and readable throughout the use of the hearing aid.

[0122] During production testing, data must first be written to different memory areas. Each area may represent a different function or store different characteristic values. For example, specific characteristic values ​​such as the production serial number, calibration parameters, and configuration information can be written to different sectors of the EEPROM.

[0123] After writing the data, the hearing aid's printed circuit board (PCB) is powered off and then powered back on. This process simulates the power outages and restarts that the device might experience in daily use. The goal is to ensure that the data in the memory is correctly preserved after the power outage and restored when the power is restored.

[0124] After powering on again, read the data at the specified address in the memory through the communication line and compare it with the previously written data. If the read data is consistent with the written data, it means that the data read and write function of the memory is normal and can correctly read the previously written value after powering on.

[0125] This embodiment ensures that memory devices, such as EEPROMs, in hearing aids can correctly store and read data. During production testing, writing signature data and verifying it through a power cycle confirms proper memory functionality, ensuring that critical configuration data is not lost or incorrectly read during actual use due to power outages.

[0126] The following describes the hearing aid production testing device provided by the present invention. The hearing aid production testing device described below and the hearing aid production testing method described above can be referenced to each other.

[0128] The detection module 310 is configured to detect at least one of a current and a voltage of each functional component in a printed circuit board of the hearing aid to be tested under a target detection configuration; the detection configuration is configured to simulate an operating mode of the hearing aid;

[0129] The acquisition module 320 is used to respectively acquire the current and voltage of each functional component when the total power consumption of the printed circuit board under the target detection configuration meets the preset power consumption condition;

[0130] The first processing module 330 is used to determine the function detection result and energy consumption detection result of each functional component based on at least one of the current and voltage of each functional component;

[0131] The second processing module 340 is configured to, when the energy consumption test result of at least one functional device is abnormal, determine a verification test configuration for verifying the abnormal result based on the abnormal functional device and the functional test result of the abnormal functional device; the verification test configuration and the target test configuration simulate a different working mode;

[0132] The third processing module 350 is configured to re-detect at least one of the current and the voltage of the functional component with abnormal energy consumption in the previous detection under the verification configuration, and determine the energy consumption detection result of the hearing aid to be tested.

[0133] The hearing aid production testing device provided by an embodiment of the present invention can more accurately locate the root cause of problems and improve testing efficiency and accuracy by separately detecting the voltage and current data of each functional component and combining functional testing with energy consumption testing.
