The invention provides an earphone adjusting method, which is used for adjusting the resistance value of a microphone circuit according to the use duration of an earphone so as to ensure the sensitivity of a microphone and improve the use experience of a user.
In a first embodiment of the present invention, as shown in fig. 2, the earphone adjusting method includes the steps of:
s100, acquiring the use duration of the earphone;
the using time of the earphone can be the accumulated time of the actual operation of the earphone; or the accumulated time length of the earphone used for the first time till now; or, considering the difference of the microphone sensitivity changes of the earphone in the actual operation state and the interrupt operation state, the using time length of the earphone can be converted according to a certain weight. Different use time lengths are defined to have certain influence on the determination of the target resistance value and the like in the subsequent step, and the target resistance value is only matched with the use time length under the current specific definition. The service time can be accumulated by a timing circuit, or can be obtained by reading the time in a mobile terminal and other devices connected with the earphone and calculating the difference between the starting time and the shutdown time of the earphone.
Step S200, determining a target resistance value of a microphone circuit of the earphone according to the using time length;
the microphone is an energy conversion device for converting a sound signal into an electric signal, the sensitivity of the microphone changes along with the accumulation of the using time, and the adjustment of the sensitivity of the microphone is realized by adjusting the resistance value of a microphone circuit. And determining a target resistance value of the microphone circuit according to the using time of the earphone. The target resistance value can be calculated according to a resistance value model between the using time and the target resistance value, and the resistance value model can be obtained by drawing or fitting experimental data of microphones of the same model to obtain a functional relation, or by collecting using data of the microphones of the same model and analyzing related data of a large number of microphones of the same model.
And step S300, adjusting a microphone circuit according to the target resistance value so that the sensitivity of the microphone of the earphone is greater than or equal to the preset sensitivity.
In a specific example, the resistance value of the microphone circuit can be directly adjusted to the target resistance value to adjust the sensitivity of the microphone to meet the requirement of being greater than or equal to the preset sensitivity. However, in consideration of the fact that the target resistance obtained according to the resistance model substantially reflects the overall properties of microphones of the same model, and the properties of the microphones often differ, in another specific example, the resistance of the microphone circuit is specifically adjusted within a certain range around the target resistance by taking the target resistance as a reference, so as to find the optimal resistance of the microphone circuit, and make the sensitivity of the microphone greater than or equal to the preset sensitivity. The preset sensitivity is preset according to the user requirement, generally, one preset sensitivity exists for one earphone, and of course, multiple preset sensitivities can be set for the same earphone to correspond to different use scenes. And the user can select the preset sensitivity by selecting the use scene so as to realize more flexible adjustment of the performance of the earphone.
In this embodiment, the earphone adjusting method includes the following steps: acquiring the use duration of the earphone; determining a target resistance value of a microphone circuit of the earphone according to the using time length; and adjusting the microphone circuit according to the target resistance value so that the sensitivity of the microphone of the earphone is greater than or equal to the preset sensitivity. In the scheme, the resistance value of the microphone circuit is adaptively adjusted according to the use duration of the earphone, so that the sensitivity of the microphone is compensated, the stability of the performance of the earphone is guaranteed, the earphone which is accumulated for a certain use duration still has the acoustic performance which is consistent with a brand new earphone or basically consistent with the brand new earphone, and the use experience of a user is improved.
Based on the first embodiment described above, as shown in fig. 3, in the second embodiment of the present invention, after step S300, the earphone adjusting method further includes the steps of:
step S410, when the sensitivity of a microphone of the earphone is larger than or equal to the preset sensitivity, acquiring a first detection resistance value of a microphone circuit and a first detection sensitivity of the microphone in the current state;
step S420, correspondingly storing a first detection resistance value and a first detection sensitivity;
and step S430, optimizing a resistance value model for determining the target resistance value by adopting a machine learning mode according to the using time length, the first detection resistance value and the first detection sensitivity.
In practical situations, the sensitivity of the microphones may not change linearly, and when the sensitivity of the microphones changes more complicatedly, the resistance model itself for determining the target resistance is also more complicated, and the preset resistance model may not completely conform to the characteristics of each microphone. Therefore, after the sensitivity of the microphone in the earphone is adjusted each time, the resistance value of the microphone circuit and the sensitivity of the microphone in the current state are detected to obtain a first detection resistance value and a first detection sensitivity, and the first detection resistance value and the first detection sensitivity are correspondingly stored to obtain the relation between the resistance value of the microphone circuit and the sensitivity of the microphone. Furthermore, the resistance model is optimized according to the use duration of the earphone, the first detection resistance and the first detection sensitivity, so that the accuracy of the resistance model is improved, and the adjustment process of the microphone sensitivity is simplified later. The resistance model can be optimized in a machine learning mode, and when a certain number of groups of corresponding first detection resistances and first detection sensitivities are accumulated, one of the groups of first detection resistances and first detection sensitivities is used as an input group, the other group of first detection resistances and first detection sensitivities is used as a test group, and the resistance model is optimized so that the resistance model can adapt to the performance change of the earphone or the development of the microphone circuit.
Based on the above embodiments, as shown in fig. 4, in the third embodiment of the present invention, after step S300, the earphone adjusting method further includes the steps of:
step S510, when the sensitivity of a microphone of the earphone is larger than or equal to the preset sensitivity, acquiring a second detection resistance value of the microphone circuit in the current state;
step S520, comparing the second detection resistance value with a preset resistance value range;
step S530, when the second detection resistance value is out of the preset resistance value range, a first prompt signal is generated.
In this embodiment, considering that the components such as the microphone and the microphone circuit in the earphone have a certain life and characteristic parameter range, after the usage time is accumulated to a certain extent, although the microphone sensitivity greater than or equal to the preset sensitivity can be obtained by adjusting the resistance value of the microphone circuit, at this time, the microphone circuit is often close to the limit of the adjustable range, and the matching effect between the microphone circuit and other components in the earphone may also be degraded, resulting in the stability of the overall performance of the earphone being reduced. The performance state of the earphone in the current state can be estimated by comparing the second detection resistance of the microphone circuit in the current state with the preset resistance range. The preset resistance range corresponds to a stage in which the performance of each component in the earphone is relatively excellent and stable, and when the second detection resistance is out of the preset resistance range, the performance deviation of each component in the microphone is larger, although the sensitivity of the microphone can be improved by adjusting the resistance of a microphone circuit, the earphone can be maintained in a better mode such as component replacement under the condition. At this time, the user is prompted in advance by generating the first prompt signal, so that the use experience of the user is prevented from being reduced after the performance of the earphone is reduced to an unadjustable degree.
Based on the above embodiments, as shown in fig. 5, in a fourth embodiment of the present invention, step S200 includes:
step S210, comparing the use duration with a preset duration;
step S220, when the using time length is longer than or equal to the preset time length, calculating a target resistance value according to the using time length and the resistance value model;
and step S230, when the use duration is less than the preset duration, continuing to accumulate the use duration.
In this embodiment, in order to balance the performance of the headset and the adjustment efficiency, the sensitivity of the microphone in the headset is adjusted after the accumulated usage time reaches the preset time. The preset time can be set according to the stability of the earphone, and for the earphone with better stability, longer preset time can be set so as to improve the adjustment efficiency and avoid unnecessary multiple adjustments; for the earphone with poor stability, the preset time can be set to be shorter so as to better guarantee the stability of the performance of the earphone. Further, in order to avoid that the microphone circuit is in a state of continuous adjustment because the use time length is not cleared and is always greater than the preset time length after the adjustment, the microphone circuit is cleared and the use time length is accumulated again after the sensitivity of the microphone is adjusted every time, so that the normal operation of the adjustment is ensured.
Based on the above embodiments, as shown in fig. 6, in a fifth embodiment of the present invention, step S300 includes:
step S310, adjusting the resistance value of the microphone circuit to be a target resistance value;
step S320, acquiring a second detection sensitivity of the microphone in the current state;
step S330, comparing the second detection sensitivity with a preset sensitivity;
step S340, when the second detection sensitivity is smaller than the preset sensitivity, adjusting the resistance value of the microphone circuit;
returning to step S320 until the second detection sensitivity is greater than or equal to the preset sensitivity.
In the present embodiment, the resistance value of the microphone circuit is adjusted with the target resistance value as a reference. Firstly, adjusting the resistance value of the microphone circuit to a target resistance value, acquiring second detection sensitivity of the microphone circuit in the current state, if the second detection sensitivity is smaller than the preset sensitivity, indicating that a larger difference exists between the target resistance value and the optimal resistance value of the microphone circuit, and further finely adjusting the resistance value of the microphone circuit according to a certain rule. In the fine adjustment process, the resistance range, the adjustment direction and the like of the microphone circuit can be limited to improve the adjustment efficiency. In general, the sensitivity of the microphone and the resistance of the microphone circuit have a monotonic relationship, and therefore, the resistance of the microphone circuit can be adjusted in a single direction from small to large or from large to small so that the second detection sensitivity of the microphone is greater than or equal to the preset sensitivity. Of course, if the acquired second detection sensitivity is already greater than or equal to the preset sensitivity after the resistance value of the microphone circuit is adjusted to the target resistance value, the adjustment may be directly ended.
Based on the above-mentioned fifth embodiment, in the sixth embodiment of the present invention, after step S340, the following steps are further included:
step S351, accumulating the adjusting times of the resistance value of the microphone circuit;
step S352, comparing the adjusting times with preset times;
and S353, stopping adjusting the resistance value of the microphone circuit when the adjusting times are larger than or equal to the preset times, and generating a second prompt signal.
In the present embodiment, it is considered that when the microphone or the microphone circuit is used for a long time, the performance degradation is severe, and it may not be possible to adjust the sensitivity to be greater than or equal to the preset sensitivity based on the existing microphone or microphone circuit. Therefore, the number of times of adjustment to adjust the resistance value of the microphone circuit is accumulated in the adjustment process. And if the accumulated adjusting times are larger than or equal to the preset times, stopping adjusting the resistance value of the microphone circuit and generating a second prompt signal to prompt a user to replace the corresponding component.
