Referring to FIG. 2, FIG. 2 is a schematic flowchart of the first embodiment of the calibration method of the bone voiceprint sensor of the present application, and the method includes:
步骤S101：分别获取待校准骨声纹传感器和标准骨声纹传感器响应第一振动信号发出的第一测试信号和第一标准信号；Step S101: respectively acquiring a first test signal and a first standard signal sent by the to-be-calibrated bone voiceprint sensor and the standard bone voiceprint sensor in response to the first vibration signal;
一般地，骨声纹传感器包括壳体以及设置在所述壳体内腔中的质量元件和弹性元件。质量元件通过振膜悬挂在壳体内腔中，质量元件与振膜组成了振动元件。质量元件与弹性元件连接在一起后将所述壳体内腔分隔为第一腔室和第二腔室两部分。所述骨声纹传感器还包括由基板、外壳围成的具有容纳腔的封装的感测元件。所述容纳腔内或者外壳中置有MEMS（Micro-Electro-Mechanical
System,微机电***）芯片、ASIC（Application
Specific Integrated Circuit，特殊应用集成电路）芯片。Generally, a bone voiceprint sensor includes a housing and a mass element and an elastic element disposed in the inner cavity of the housing. The mass element is suspended in the inner cavity of the housing through the vibrating membrane, and the mass element and the vibrating membrane constitute a vibrating element. After the mass element and the elastic element are connected together, the inner cavity of the housing is divided into two parts: the first cavity and the second cavity. The bone voiceprint sensor further includes a packaged sensing element with an accommodating cavity enclosed by the base plate and the housing. MEMS (Micro-Electro-Mechanical
System, microelectromechanical system) chip, ASIC (Application
Specific Integrated Circuit, special application integrated circuit) chip.
骨声纹传感器广泛应用于耳机、助听器等穿戴设备。所述骨声纹传感器在使用时，被安装到以振动方式发出声音的被检测物体上，例如安装到人的关节、机器人的关节等位置。被检测物体的振动会带动壳体产生振动，在质量元件的惯性和弹性元件的弹性共同作用下，质量元件会相对壳体发生振动。质量元件和弹性元件的振动使得第一腔室和第二腔室内的气体的压强发生变化。所述感测元件检测到所述第一腔室与所述第二腔室的压强差，并将压强差转换为电信号，再对所述电信号进行解析获得待检测物体的振动状态。Bone voiceprint sensors are widely used in wearable devices such as headphones and hearing aids. When the bone voiceprint sensor is in use, it is installed on the detected object that emits sound in a vibrating manner, for example, it is installed on a joint of a human, a joint of a robot, and the like. The vibration of the detected object will drive the casing to vibrate. Under the combined action of the inertia of the mass element and the elasticity of the elastic element, the mass element will vibrate relative to the casing. The vibration of the mass element and the elastic element changes the pressure of the gas in the first chamber and the second chamber. The sensing element detects the pressure difference between the first chamber and the second chamber, converts the pressure difference into an electrical signal, and then analyzes the electrical signal to obtain the vibration state of the object to be detected.
本实施例通过检测工装对封装后、出厂前的待校准骨声纹传感器进行校准。所述检测工装包括工装底座，以及依次设置在所述工装底座上的PCB（Printed
Circuit Board，印刷电路板）检测单元、待校准骨声纹传感器固定单元和工装上盖；其中，在所述工装底座上设置有用于锁紧所述PCB检测单元、所述待校准骨声纹传感器固定单元和所述工装上盖的锁紧单元；所述PCB检测单元包括多个用于为所述待校准骨声纹传感器供电并接收所述待校准骨声纹传感器信号的PCB模块；所述待校准骨声纹传感器固定单元包括固定基座和设置在所述固定基座上的多个检测室，每个检测室对应一个PCB模块，在所述检测室底部设置有检测探针；所述待校准骨声纹传感器定位在所述检测室内，并通过所述检测探针与其对应的PCB模块电连接。需要说明的是，所述测试工装稳固放置于振动台上，所述振动台为待校准骨声纹传感器提供振动信号。In this embodiment, a detection tool is used to calibrate the bone voiceprint sensor to be calibrated after packaging and before leaving the factory. The detection tooling includes a tooling base, and a PCB (Printed
Circuit Board, printed circuit board) detection unit, a bone voiceprint sensor to be calibrated fixing unit and a tooling upper cover; wherein, the tooling base is provided with a function for locking the PCB detection unit, the bone voiceprint sensor to be calibrated a fixing unit and a locking unit of the upper cover of the tooling; the PCB detection unit includes a plurality of PCB modules for supplying power to the to-be-calibrated bone voiceprint sensor and receiving signals from the to-be-calibrated bone voiceprint sensor; the The fixing unit of the bone voiceprint sensor to be calibrated includes a fixing base and a plurality of detection chambers arranged on the fixing base, each detection chamber corresponds to a PCB module, and a detection probe is arranged at the bottom of the detection chamber; The bone voiceprint sensor to be calibrated is positioned in the detection chamber, and is electrically connected to its corresponding PCB module through the detection probe. It should be noted that the test tool is firmly placed on a vibration table, and the vibration table provides vibration signals for the bone voiceprint sensor to be calibrated.
本实施例通过所述振动台发出所述第一振动信号。所述振动台可以将低频音频信号转换为振动信号。本实施例中所述第一振动信号可以是具有一定加速度固定频率以及固定幅值的电压信号。In this embodiment, the first vibration signal is sent out through the vibration table. The vibration table can convert low frequency audio signals into vibration signals. In this embodiment, the first vibration signal may be a voltage signal with a certain acceleration, a fixed frequency and a fixed amplitude.
在校准前，将所述待校准骨声纹传感器和所述标准骨声纹传感器置于测试工件的检测室，上电并输入第一振动信号后，所述待校准骨声纹传感器和所述标准骨声纹传感器响应所述第一振动信号分别输出第一测试信号和第一标准信号。具体地，所述第一测试信号或所述第一标准信号可以是对应加速度传感器采集的所述第一振动信号的加速度。Before calibration, place the to-be-calibrated bone voiceprint sensor and the standard bone-voiceprint sensor in the testing room of the test workpiece, power on and input the first vibration signal, the to-be-calibrated bone voiceprint sensor and the The standard bone voiceprint sensor outputs a first test signal and a first standard signal respectively in response to the first vibration signal. Specifically, the first test signal or the first standard signal may be an acceleration corresponding to the first vibration signal collected by an acceleration sensor.
当获得所述第一测试信号和所述第一标准信号后，执行步骤S102：基于所述第一测试信号、所述第一标准信号确定所述待校准骨声纹传感器的第一偏差，判断所述第一偏差是否在预设范围内；After the first test signal and the first standard signal are obtained, step S102 is performed: determine the first deviation of the to-be-calibrated bone voiceprint sensor based on the first test signal and the first standard signal, and determine Whether the first deviation is within a preset range;
本实施例中，将所述第一标准信号与所述第一测试信号的差值确定为所述第一偏差。也即第一偏差=第一标准信号-第一测试信号。可以理解地，在实际校准过程中，所述测试工装有一定范围的可允许误差，若测试环境有干扰信号也会导致干扰误差的产生，虽然这些***误差会对测试结果产生影响，但是这些***误差是无法避免的。因此如果不利用所述标准骨声纹传感器，则每批次测试的***误差不相同，在判断标准固定的情况下，会由于***误差的原因导致判断不准确。In this embodiment, the difference between the first standard signal and the first test signal is determined as the first deviation. That is, the first deviation=the first standard signal-the first test signal. Understandably, in the actual calibration process, the test tool is equipped with a certain range of allowable errors. If there are interference signals in the test environment, interference errors will also occur. Although these system errors will have an impact on the test results, these systems Errors are unavoidable. Therefore, if the standard bone voiceprint sensor is not used, the systematic errors of each batch of tests will be different, and in the case where the judgment standard is fixed, the judgment will be inaccurate due to the systematic error.
本实施例中，假设所述标准骨声纹传感器的灵敏度为100%，其自身误差为0，在理想情况下，所述标准骨声纹传感器发出的所述第一标准信号与所述第一振动信号相同。但是由于***误差的存在，所述第一标准信号会略小于所述第一振动信号。所述第一标准信号与所述第一振动信号的差值即为***误差。因此，将所述第一标准信号与所述第一测试信号的差值作为第一偏差即相当于消除了所述***误差对所述第一测试信号带来的影响。In this embodiment, it is assumed that the sensitivity of the standard bone voiceprint sensor is 100% and its own error is 0. In an ideal situation, the first standard signal sent by the standard bone voiceprint sensor and the first standard signal The vibration signal is the same. However, due to the existence of systematic errors, the first standard signal may be slightly smaller than the first vibration signal. The difference between the first standard signal and the first vibration signal is the system error. Therefore, taking the difference between the first standard signal and the first test signal as the first deviation is equivalent to eliminating the influence of the system error on the first test signal.
可以理解地，所述第一偏差越小，则说明所述待校准骨声纹传感器的自身误差越小，其灵敏度越高，但是刚刚封装好的骨声纹传感器往往会由于封装位置差异、封装方式等原因导致一定的自身误差，为了将自身误差降至最小，提高待校准骨声纹传感器的灵敏度，需要对封装后、出厂前的待校准骨声纹传感器进行校准。Understandably, the smaller the first deviation, the smaller the self-error of the bone voiceprint sensor to be calibrated, and the higher the sensitivity. In order to minimize the self-error and improve the sensitivity of the bone voiceprint sensor to be calibrated, it is necessary to calibrate the bone voiceprint sensor to be calibrated after packaging and before leaving the factory.
本实施例设置所述第一偏差的预设范围，所述范围可以实际需要调整。例如将所述预设范围设置为小于或等于所述第一标准信号的5%，也即所述预设范围为[0，第一标准信号×5%]。In this embodiment, a preset range of the first deviation is set, and the range may be adjusted according to actual needs. For example, the preset range is set to be less than or equal to 5% of the first standard signal, that is, the preset range is [0, first standard signal×5%].
获得所述第一偏差是否在预设范围内的判断结果后，则执行步骤S103：若所述第一偏差在预设范围内，则基于目标信号和所述第一测试信号确定增益值，并基于所述增益值对所述待校准骨声纹传感器进行校准。After obtaining the judgment result of whether the first deviation is within the preset range, step S103 is performed: if the first deviation is within the preset range, the gain value is determined based on the target signal and the first test signal, and The bone voiceprint sensor to be calibrated is calibrated based on the gain value.
若所述第一偏差在预设范围内，则说明所述待校准骨声纹传感器的自身偏差比较小，值得进一步进行校准。If the first deviation is within the preset range, it means that the self-deviation of the bone voiceprint sensor to be calibrated is relatively small, and it is worthy of further calibration.
所述增益值包括偏置电压和/或放大倍数中。将所述目标信号与所述第一测试信号的差值确定为偏置电压；或将所述目标信号与所述第一测试信号的比值确定为放大倍数。其中，所述目标信号为能获得高灵敏度的骨声纹传感器的理想目标信号，校准后的骨声纹传感器的校准后信号越接近所述目标信号，则灵敏度越高。The gain value includes bias voltage and/or amplification factor. The difference between the target signal and the first test signal is determined as a bias voltage; or the ratio of the target signal and the first test signal is determined as an amplification factor. The target signal is an ideal target signal for obtaining a high-sensitivity bone voiceprint sensor, and the closer the calibrated signal of the calibrated bone voiceprint sensor is to the target signal, the higher the sensitivity.
本实施例以烧录的方式将所述增益值烧录至所述待校准骨声纹传感器的芯片中，如此烧录后的校准骨声纹传感器的信号即可接近甚至达到目标信号。In this embodiment, the gain value is programmed into the chip of the bone voiceprint sensor to be calibrated by programming, so that the programmed signal of the calibrated bone voiceprint sensor can approach or even reach the target signal.
进一步地，若所述第一偏差不在所述预设范围内，则重新测试获得新的第一测试信号，并确定新的第一偏差；若测试次数达到最大限制次数后，所述新的第一偏差不在所述预设范围内，则终止校准并发出提示信息。若测试多次获得的第一偏差都不在预设范围内，则说明所述校准骨声纹传感器的自身误差比较大，属于完全不合格的产品，难以通过校准的方式获得较高的灵敏度，因此直接终止对不合格的待校准骨声纹传感器的校准流程，将其标记为不合格产品并发出提示信息。Further, if the first deviation is not within the preset range, re-test to obtain a new first test signal, and determine a new first deviation; if the number of tests reaches the maximum limit, the new first test signal is determined. If the deviation is not within the preset range, the calibration is terminated and a prompt message is issued. If the first deviation obtained by multiple tests is not within the preset range, it means that the calibration error of the bone voiceprint sensor is relatively large, and it is a completely unqualified product, and it is difficult to obtain high sensitivity through calibration. Directly terminate the calibration process for unqualified bone voiceprint sensors to be calibrated, mark them as unqualified products and issue a prompt message.
当所述待校准骨声纹传感器烧录后，为了验证校准效果，进一步执行以下步骤：通过校准后的骨声纹传感器响应第二振动信号输出第二测试信号；基于所述第二测试信号判断所述骨声纹传感器是否合格；若所述骨声纹传感器合格，则完成校准过程；若所述骨声纹传感器不合格，则终止校准并发出提示信息。在烧录完成后，可能会由于烧录工艺或者增益值录入错误等原因导致烧录后的骨声纹传感器并不符合要求，因此需要进行二次验证。本实施例中，所述第二振动信号可以与所述第一振动信号相同，也可以与所述第一振动信号不相同。根据所述第二振动信号以及目标灵敏度确定第二测试信号的最低值，第二测试信号的最低值=第二振动信号×目标灵敏度，若目标灵敏度是98%，则第二测试信号的最低值=第二振动信号×98%。若所述第二测试信号大于或等于所述第二测试信号的最低值，则判定所述骨声纹传感器合格；反之，若所述第二测试信号小于所述第二测试信号的最低值，则判定所述骨声纹传感器不合格。After the to-be-calibrated bone voiceprint sensor is programmed, in order to verify the calibration effect, the following steps are further performed: the calibrated bone voiceprint sensor responds to the second vibration signal and outputs a second test signal; based on the second test signal, determine Whether the bone voiceprint sensor is qualified; if the bone voiceprint sensor is qualified, the calibration process is completed; if the bone voiceprint sensor is unqualified, the calibration is terminated and a prompt message is sent. After the burning is completed, the burned bone voiceprint sensor may not meet the requirements due to the burning process or the input error of the gain value, so a second verification is required. In this embodiment, the second vibration signal may be the same as the first vibration signal, or may be different from the first vibration signal. Determine the lowest value of the second test signal according to the second vibration signal and the target sensitivity, the lowest value of the second test signal=the second vibration signal×target sensitivity, if the target sensitivity is 98%, then the lowest value of the second test signal = Second vibration signal × 98%. If the second test signal is greater than or equal to the minimum value of the second test signal, it is determined that the bone voiceprint sensor is qualified; otherwise, if the second test signal is less than the minimum value of the second test signal, Then it is determined that the bone voiceprint sensor is unqualified.
本实施例通过上述方案，分别获取待校准骨声纹传感器和标准骨声纹传感器响应第一振动信号发出的第一测试信号和第一标准信号；基于所述第一测试信号、所述第一标准信号确定所述待校准骨声纹传感器的第一偏差，判断所述第一偏差是否在预设范围内；若所述第一偏差在预设范围内，则基于目标信号和所述第一测试信号确定增益值，并基于所述增益值对所述待校准骨声纹传感器进行校准。由此，通过待校准骨声纹传感器和标准骨声纹传感器对振动信号的响应偏差来判断待校准骨声纹传感器是否需要进行校准，并根据增益值对需要进行校准的待校准骨声纹传感器进行校准，降低了校准过程中***误差带来的影响，提高了校准的准确性。In this embodiment, through the above solution, the first test signal and the first standard signal sent by the to-be-calibrated bone voiceprint sensor and the standard bone voiceprint sensor in response to the first vibration signal are obtained respectively; The standard signal determines the first deviation of the bone voiceprint sensor to be calibrated, and judges whether the first deviation is within the preset range; if the first deviation is within the preset range, based on the target signal and the first deviation The test signal determines a gain value, and the bone voiceprint sensor to be calibrated is calibrated based on the gain value. Therefore, it is judged whether the bone voiceprint sensor to be calibrated needs to be calibrated according to the response deviation of the bone voiceprint sensor to be calibrated and the standard bone voiceprint sensor to the vibration signal, and the bone voiceprint sensor to be calibrated needs to be calibrated according to the gain value. Calibration is performed to reduce the influence of systematic errors in the calibration process and improve the accuracy of calibration.
