Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

A bluetooth headset, such as a real wireless stereo (True Wireless Stereo, TWS) headset, is capable of receiving and outputting audio data transmitted by a terminal device after a bluetooth connection is established with the terminal device. Because of its small size and light weight, bluetooth headsets are widely used in a variety of entertainment and office settings.

In order to meet practical use requirements in diversified application scenes, the bluetooth headset needs to have diversified and flexible volume adjusting functions. In practical applications, the bluetooth headset can only determine its output volume for audio data in response to a touch operation of a user after the user touches or slides a designated area of the bluetooth headset, or output audio data according to the magnitude of the audio data sent by the terminal device.

However, the above-mentioned method for adjusting the volume of a bluetooth ear has at least the following drawbacks:

first, the bluetooth headset is smaller in size and the area available for volume adjustment on the bluetooth headset is smaller, which increases the inconvenience of volume adjustment for a finger that is larger, occupied, or a nail user.

Secondly, as the service time of the bluetooth headset is prolonged, the sensitivity of the sensor for detecting and transmitting the touch operation of the user in the bluetooth headset is reduced, which also causes accidents such as volume adjustment failure or inaccurate adjustment.

And when the output volume of the Bluetooth headset is adjusted remotely through the terminal equipment, the user needs to touch the terminal equipment, and if the user cannot or is inconvenient to operate the terminal equipment, the volume of the Bluetooth headset cannot be adjusted in time.

Based on the above problems, the embodiment of the application provides an intelligent volume determining method, device and medium.

The intelligent volume determining method provided by the embodiment of the application can be realized through a processor of the electronic equipment. The processor may be at least one of an application specific integrated circuit (Application Specific Integrated Circuit, ASIC), a digital signal processor (Digital Signal Processor, DSP), a digital signal processing device (Digital Signal Processing Device, DSPD), a programmable logic device (Programmable Logic Device, PLD), a field programmable gate array (Field Programmable Gate Array, FPGA), a central processing unit (Central Processing Unit, CPU), a controller, a microcontroller, and a microprocessor.

Fig. 1 is a schematic flow chart of an intelligent volume determining method according to an embodiment of the present application, as shown in fig. 1, the flow chart may include the following steps:

step 101, acquiring current environmental parameters of an environment where the electronic equipment is located.

In one embodiment, the current environmental parameters may include noise parameters of an environment in which the electronic device is currently located; illustratively, the noise parameter may include at least one of a noise amplitude, a noise component, and a noise frequency.

In one embodiment, the current environmental parameter may be obtained by a sensor device provided in the electronic device; for example, the sensor means may comprise an audio sensor.

In one embodiment, the sensor device may store the environmental parameter for a certain period of time, and after acquiring the current environmental parameter, if it is determined that the difference between the current environmental parameter and the environmental parameter for the certain period of time is greater than a preset difference, send the current environmental parameter to the processor.

Step 102, determining the current playing volume associated with the current environment parameter based on the association relation set between the environment parameter and the playing volume.

In one embodiment, the association relation set may include K association relations, where the K association relation may include a one-to-one association relation between the kth environment parameter and the kth play volume; wherein K is an integer greater than or equal to 2; k is an integer greater than or equal to 1 and less than or equal to K.

In one embodiment, the current play volume may be different from the historical play volume; for example, the historical play volume may include a play volume of an electronic device, such as a bluetooth headset, prior to the time at which the current environmental parameter was obtained.

In one embodiment, the current play volume may be associated with a noise amplitude and/or noise frequency in the current environmental parameters.

In one embodiment, the current play volume may be determined by:

based on the matching degree between the current environment parameter and the environment parameter contained in the association relation set, determining a target environment parameter with the matching degree larger than a matching threshold value with the current environment parameter from the association relation set, and determining the playing volume corresponding to the target environment parameter as the current playing volume.

Based on the matching degree between the current environment parameter and the environment parameter contained in the association relation set, determining a target environment parameter with the matching degree larger than a matching threshold value with the current environment parameter from the association relation set, adjusting the playing volume corresponding to the target environment parameter based on the current audio output mode, and determining the adjustment result as the current playing volume.

Step 103, adjusting the volume output by the electronic device based on the current playing volume.

In one embodiment, at least one of increasing, decreasing, or maintaining the volume output by the electronic device may be performed based on the current play volume.

Step 104, updating the association relation set at least based on the current environment parameter and the current playing volume.

In one embodiment, updating the association set between the environmental parameter and the playing volume may be implemented by any one of the following ways:

and associating the current environment parameter and the current playing volume to obtain a first result, and adding the first result into the association relation set.

And responding to the permission operation of the user, and adding the first result into the association relation set.

And determining a scene identifier corresponding to the current environment parameter, associating the scene identifier, the current playing volume and the current environment parameter to obtain a second result, and adding the second result into the association relation set.

In one embodiment, the association set may be in an initial state before being updated for the first time; for example, the association relationship set in the initial state may include a default association relationship set after the electronic device is produced, and as the electronic device is continuously used or continuously plays the audio data, the association relationship set in the initial state may be continuously updated and optimized to meet the actual audio data playing requirement of the user.

As can be seen from the above, according to the intelligent volume determining method provided by the embodiment of the application, by acquiring the current environmental parameter, the electronic device can acquire the change state of the noise in the environment where the electronic device is located in real time; and the current playing volume associated with the current environment parameter is determined based on the association relation set between the environment parameter and the playing volume, so that the automatic adjustment of the current playing volume is realized; meanwhile, the current playing volume is associated with the current environment parameter, so that the current playing volume can meet the volume output requirement under the environment state represented by the current environment parameter; on the other hand, the current playing volume is determined based on the association relation set, so that the controllability of the determining process of the current playing volume can be improved, and the probability of abnormal playing volume adjustment can be reduced in the process of adjusting the volume output by the electronic equipment based on the current playing volume; on the basis, the association relation set is updated at least based on the current environment parameters and the current playing volume, so that dynamic update of the association relation set is realized, and the updated association relation set is still used for determining the actual playing volume, so that the determining flow of the playing volume at the future moment can be optimized, and the intelligent level of the playing volume determining process is further improved.

Based on the foregoing embodiments, in the method for determining intelligent volume provided by the embodiments of the present application, updating the association relation set based on at least the current environment parameter and the current playing volume may be implemented by:

acquiring an environment parameter set contained in the association relation set; if the degree of difference between the current environment parameter and the parameters in the environment parameter set is greater than or equal to a first threshold, updating the association relation set at least based on the current environment parameter and the current playing volume.

For example, if the degree of difference between the current environmental parameter and the parameters in the set of environmental parameters is less than the first threshold, the set of associations may not be updated.

In one embodiment, the first threshold may be preset or adjustable; illustratively, the first threshold may be adjusted based on the noise sensitivity level of the user, the shape, structure, and sealing level between the audio output firmware of the electronic device, such as a Bluetooth headset, and the user's ear canal.

As can be seen from the above, in the intelligent volume determining method provided by the embodiment of the present application, after the environmental parameter set included in the association relation set is obtained, if the degree of difference between the current environmental parameter and the parameters in the environmental parameter set is greater than or equal to the first threshold, the association relation set is updated at least based on the current environmental state and the current playing volume. Therefore, on one hand, the operation of updating the association relation set is strictly controlled, and the data operand generated by randomly updating the association relation set can be reduced; on the other hand, when the degree of difference between the current environmental parameter and the parameter in the environmental parameter set is greater than or equal to the first threshold value, the association relation set is updated, so that the association relation contained in the updated association relation set can differentially reflect the corresponding relation between the environmental parameter and the output volume.

Based on the foregoing embodiments, in the method for determining intelligent volume provided by the embodiments of the present application, updating the association set based on at least the current environmental parameter and the current playing volume may also be implemented by:

and A1, acquiring an environment parameter set contained in the association relation set.

And A2, determining the environmental parameters to be updated from the environmental parameter set.

Wherein the degree of difference between the environmental parameter to be updated and the current environmental parameter is less than a second threshold.

In an embodiment, the manner of determining the second threshold may be similar to the manner of determining the first threshold, which is not described herein.

In one embodiment, where the environmental parameter represents a noise amplitude and the current environmental parameter is a current noise amplitude, the noise amplitude contained in the set of environmental parameters may be compared with the current noise amplitude in a traversal manner to determine the environmental parameter to be updated.

In one embodiment, the number of environmental parameters to be updated may be at least one.

And step A3, associating the current environment parameters and the current playing volume to obtain an association result.

And step A4, based on the association result, covering the association relation to be updated, which contains the environmental parameter to be updated, in the association relation set.

In one embodiment, when the number of parameters in the environment parameters to be updated is one, the association relationship to be updated in the association relationship set may be covered based on the association result.

In one embodiment, when the number of the environmental parameters to be updated is at least two, the association relationship with the smallest difference degree with the current environmental parameters in the association relationship to be updated may be covered based on the association result.

As can be seen from the foregoing, in the intelligent volume determining method provided by the embodiment of the present application, an environmental parameter set included in an association relation set is obtained, and after determining an environmental parameter to be updated, of which the degree of difference with a current environmental parameter is smaller than a second threshold, from the environmental parameter set, an association relation to be updated including the environmental parameter to be updated in the association relation set is covered based on an association result of associating the current environmental parameter with the current playing volume. On the one hand, the probability of overlarge data volume of the incidence relation set caused by frequent execution of the updating operation can be reduced by covering the incidence relation to be updated in the incidence relation set; on the other hand, the degree of difference between the environmental parameter to be updated and the current environmental parameter in the incidence relation to be updated is smaller than the second threshold, so that the incidence relation set is updated in a targeted manner, the redundancy of the incidence relation in the incidence relation set can be reduced, and the precise optimization of the incidence relation set can be realized.

Based on the foregoing embodiments, in the method for determining intelligent volume provided by the embodiments of the present application, updating the association relation set based on at least the current environment parameter and the current playing volume may also be implemented by:

responding to the adjustment operation of the current playing volume to obtain a volume adjustment result; and updating the association relation set based on the current environment parameters and the volume adjustment result.

In one embodiment, the adjustment operation may be performed by at least one of touch, slide, audio, and gesture control performed by a user on an electronic device such as a bluetooth headset.

In one embodiment, the adjustment operation may be performed automatically based on audio playback configuration parameters; the audio playing configuration parameters may be set manually by a user of the electronic device, or may be obtained and tracked to learn the audio playing habit of the user and analyze the audio playing habit under the condition that the electronic device obtains the user permission, so as to determine the audio playing configuration parameters; illustratively, the audio play configuration parameters may include an audio play mode and/or audio adjustment conditions, etc.

In one embodiment, the volume adjustment may include an adjustment for the magnitude and/or mode of the current play volume; illustratively, the amplitude and/or mode corresponding to the volume adjustment result may be the same as or different from the amplitude and/or mode corresponding to the current playing volume; for example, the modes may include at least one of a stereo mode, a monaural mode, an active noise reduction mode, and an inactive noise reduction mode.

By way of example, the association relation set may be updated based on the current environmental parameter and the volume adjustment result by the method provided in the foregoing embodiment.

As can be seen from the above, in the intelligent volume determining method provided by the embodiment of the present application, after the volume adjustment result is obtained in response to the adjustment operation for the current playing volume, the association relation set is updated based on the current environment parameter and the volume adjustment result. In this way, in the process of updating the association relation set, the factor of the adjustment operation for the current playing volume is added, so that the controllability and the friendliness of the operation of updating the association relation set are improved; moreover, through the operation, the updated association relation set can meet the actual audio playing requirement of the user.

Based on the foregoing embodiment, in the intelligent volume determining method provided by the embodiment of the present application, the determining of the current playing volume associated with the current environmental parameter based on the association relation set between the environmental parameter and the playing volume may be implemented by the following steps:

The degree of difference between the N associated environment parameters and the current environment parameter is smaller than a third threshold value; n is an integer greater than or equal to 2.

In one embodiment, the third threshold may be greater than the first threshold; the third threshold may be determined in response to a user setting, or may be changed as the audio output mode is switched, for example.

In one embodiment, the volume fitting strategy may include a following changing relationship between the N play volumes and the N associated environmental parameters within an environmental parameter interval characterized by the N associated environmental parameters.

In one embodiment, the volume fitting policy may include a functional relationship between N output volumes and N associated environment parameters, where the N associated environment parameters may be independent variables and the N play volumes may be dependent variables.

In one embodiment, the volume fitting strategy may be determined by:

and counting the discrete distribution states of N associated environment parameters and N play volumes, fitting the continuous adjustment trend of the play volumes in the environment parameter interval represented by the N associated environment parameters based on the distribution states, and determining the adjustment trend as a volume fitting strategy.

And B3, determining the current playing volume based on the volume fitting strategy and the current environment parameters.

In one embodiment, the current play volume may be determined by any of the following means:

and adjusting and converting the current environment parameters based on the first parameters for adjusting the environment parameters contained in the volume fitting strategy, and determining the adjustment and conversion result as the current playing volume.

The method comprises the steps that based on the fact that a second parameter for strengthening or weakening the playing volume according to the environment parameter and the current environment state are included in a volume fitting strategy, historical playing volume is strengthened or weakened, and the processing result is determined to be the current playing volume; the historical playing volume may include the playing volume of the electronic device at the moment of acquiring the current environmental parameter, and may further include N playing volumes.

As can be seen from the above, in the intelligent volume determining method provided by the embodiment of the present application, N associated environmental parameters and N playing volumes are determined from the association relation set based on the current environmental parameter, and as the degree of difference between the N associated environmental parameters and the current environmental parameter is smaller than the third threshold, the N associated environmental parameters represent the change state in the interval of the associated environmental parameters with the third threshold, and also the volume change trend represented by the N playing volumes can satisfy the volume playing requirement under the current environmental parameter; and the volume fitting strategy is determined based on N associated environment parameters and N play volumes, so that the volume fitting strategy can accurately reflect the interaction between the associated environment parameters and the play volumes and follow the changed state in the range of the associated environment parameters and the third threshold; therefore, the current playing volume determined based on the volume fitting strategy and the current environment parameter can meet the audio playing requirement under the current environment characterized by the current environment parameter.

Based on the foregoing embodiments, in the intelligent volume determining method provided by the embodiment of the present application, the volume fitting policy is determined based on N associated environmental parameters and N play volumes, and may be implemented by the following steps:

And C1, determining the magnitude relation between the current environment parameter and N associated environment parameters.

In one embodiment, the magnitude relationship may represent whether the current environmental parameter is within an environmental parameter interval characterized by N associated environmental parameters.

In one embodiment, the magnitude relation may indicate that the current environmental parameter is less than the smallest of the N associated environmental parameters.

In one embodiment, the magnitude relationship may indicate that the current environmental parameter is greater than a largest parameter of the N associated environmental parameters.

And C2, determining a fitting relation between the N associated environment parameters and the N play volumes based on the size relation, the N associated environment parameters and the N play volumes.

In one embodiment, the fit relationship may include a course or trend of N play volumes as a function of N associated environmental parameters.

In one embodiment, the fit relationship may be embodied in the form of a function; illustratively, the above-described function may be in linear and/or nonlinear form, whereby the continuity characterizes the process of varying N play volumes with the variation of N associated environmental parameters.

In one embodiment, the fitting relationship may represent, in a segmented form, a change in N play volumes in different subintervals of the environmental parameter interval characterized by the N associated environmental parameters.

In one embodiment, the fit relationship may vary with size relationship.

In one embodiment, the fit relationship may be determined by any of the following means:

if the magnitude relation indicates that the current environmental parameter is located in the environmental parameter interval represented by the N associated environmental parameters, the following change relation between the N associated environmental parameters and the N playing volumes can be counted, the discrete following change relation is fitted into a continuous change relation between the environmental parameters and the playing volumes in the environmental parameter interval represented by the N associated environmental parameters, and then the continuous change relation is determined as a fitting relation.

If the magnitude relation indicates that the current environmental parameter is smaller than the minimum parameter of the N associated environmental parameters, predicting a first prediction relation between the environmental parameter and the playing volume within an environmental parameter range smaller than the minimum parameter of the N associated environmental parameters according to the continuous change relation determined in the above, and then determining the first prediction relation as a fitting relation.

If the magnitude relation indicates that the current environmental parameter is greater than the maximum parameter of the N associated environmental parameters, predicting a second prediction relation between the environmental parameter and the playing volume within the environmental parameter range greater than the maximum parameter of the N associated environmental parameters according to the continuous change relation determined above, and determining the second prediction relation as a fitting relation.

And C3, determining a volume fitting strategy based on the fitting relation.

In one embodiment, the volume fitting strategy may be determined by:

determining a weight parameter, weighting the fitting relation based on the weight parameter, and determining a processing result as a volume fitting strategy; the weight parameter may be associated with at least one of an audio output mode, a power consumption state, a play scene, and a usage habit of the user of the electronic device.

As can be seen from the above, in the intelligent volume determining method provided by the embodiment of the present application, after determining the magnitude relation between the current environmental parameter and the N associated environmental parameters, the fitting relation between the N associated environmental parameters and the N play volumes is determined based on the magnitude relation, the N associated environmental parameters and the N play volumes. Therefore, the targeted adjustment of the association relation between the N association environment parameters and the N play volumes based on the size relation is realized, namely the targeted adjustment of the association relation based on the current environment parameters is realized, so that the fitting relation can embody the relation of the mutual influence between the N association environment parameters and the N play volumes, and can embody the directional influence of the current environment parameters on the relation; on the basis, the volume fitting strategy is determined based on the fitting relation, so that the consistency between the volume fitting strategy and the current environment parameter can be improved, and the accuracy of the volume fitting strategy is improved.

Based on the foregoing embodiments, in the intelligent volume determining method provided by the embodiments of the present application, the current playing volume is determined based on the volume fitting policy and the current environmental parameter, and may be implemented by the following ways:

As can be seen from the above, in the intelligent volume determining method provided by the embodiment of the present application, based on the volume fitting policy, the fitting relationship between N associated environmental parameters and N playing volumes included in the association relationship set is determined, and since the degree of difference between the N associated environmental parameters and the current environmental parameter is smaller than the third threshold, and the N associated environmental parameters are associated to the N playing volumes, the fitting relationship can comprehensively and accurately represent the changing process of the N playing volumes in the environmental parameter interval represented by the N associated environmental parameters; and the fitting relation can flexibly represent the variation trend of the playing volume along with the environmental parameters in the adjustable environmental parameter interval by adjusting the third threshold; on the basis, the fitting relation is associated with the current environment parameters, so that the current playing volume obtained by fitting and adjusting the current environment parameters based on the fitting relation can meet the playing requirement of the audio data in the current environment state.

Based on the foregoing embodiment, in the method for determining an intelligent volume according to the embodiment of the present application, based on the set of association relationships between the environmental parameters and the play volume, determining the current play volume associated with the current environmental parameter may also be implemented by:

For example, if the degree of difference between the current environmental parameter and the historical environmental parameter is smaller than the fourth threshold, the operation of determining the current playing volume based on the association relation set and the current environmental parameter may not be performed.

In one embodiment, the historical environmental parameters may include environmental parameters acquired at a time prior to the acquisition of the current environmental parameters.

In one embodiment, the degree of difference between the current environmental parameter and the historical environmental parameter is greater than or equal to the fourth threshold value, which may indicate that the state of the environment in which the electronic device is located has changed significantly, or that the environment in which the electronic device is located has changed significantly.

In one embodiment, the degree of difference between the current environmental parameter and the historical environmental parameter is greater than or equal to the fourth threshold, which may indicate a historical playing volume corresponding to the historical environmental parameter, and cannot satisfy the playing requirement under the environmental state represented by the current environmental parameter.

As can be seen from the above, in the intelligent volume determining method provided by the embodiment of the present application, if the degree of difference between the current environmental parameter and the historical environmental parameter is greater than or equal to the fourth threshold, the current playing volume is determined based on the association relation set and the current environmental parameter. Therefore, on one hand, the targeted adjustment and determination of the playing volume of the electronic equipment are realized, and on the other hand, the fourth threshold value is adjusted, so that the diversified adjustment of the playing volume can be realized.

Based on the foregoing embodiment, in the intelligent volume determining method provided by the embodiment of the present application, the current environmental parameter includes an environmental parameter in a current period.

In one embodiment, the current period of time may be preset, or may be adjusted according to at least one of a playing scene, a user habit, and a playing mode.

In one embodiment, the environmental parameters may be acquired at preset time intervals during a current period, and the set of the acquired plurality of environmental parameters may be determined as the current environmental parameter.

In one embodiment, environmental parameters may be collected during a first period of time at a first time interval to obtain a first parameter set, and the first parameter set is counted; if the change frequency of the environmental parameters in the first parameter set is larger than the preset frequency, continuously collecting the environmental parameters in a second period of time at a second time interval to obtain a second parameter set, and determining the first parameter set and the second parameter set as current environmental parameters; if the change frequency of the environmental parameters in the first parameter set is smaller than the preset frequency, continuously collecting environmental data in a second period of time at a third time interval to obtain a second parameter set; the current time period may include a first time period and a second time period, and the first time interval may be smaller than the second time interval and larger than the third time interval.

Accordingly, based on the association relation set between the environment parameter and the play volume, determining the current play volume associated with the current environment parameter can also be realized by the following ways:

if the current environment parameter indicates that the change frequency of the environment parameter in the current period is greater than the frequency threshold, determining the current playing volume at least based on the association relation set and the current environment parameter.

For example, if the current environmental parameter indicates that the frequency of change of the environmental parameter within the current period is less than or equal to the frequency threshold, the operation of determining the current playing quality based at least on the set of association relationships and the current environmental parameter may not be performed.

In one embodiment, if the current environmental parameter indicates that the frequency of the change of the environmental parameter in the current period is greater than the frequency threshold, the noise amplitude represented by the current environmental parameter may indicate that frequent changes occur in the current period, and at this time, the current playing volume may be determined with respect to the association relation set and the current environmental parameter, and the following property.

In one embodiment, if the current environmental parameter indicates that the change frequency of the environmental parameter in the current period is greater than the frequency threshold, a prompt message can be output, a preset or user-input volume adjustment frequency is determined, and then the current playing volume is determined based on the association relation set and the current environmental parameter in the period corresponding to the volume adjustment frequency; the prompt information may include information that the current environmental parameter indicates that the change frequency of the environmental parameter in the current period is greater than a frequency threshold value, and that a higher frequency adjustment of the playing volume is required.

As can be seen from the above, in the intelligent volume determining method provided by the embodiment of the present application, if the current environmental parameter indicates that the change frequency of the environmental parameter in the current period is greater than the frequency threshold, the current playing volume is determined at least based on the association relation set and the current environmental parameter. Therefore, on one hand, the operation of determining the current playing volume is strictly controlled, so that the data power consumption generated by frequently determining the current playing volume can be reduced; on the other hand, by adjusting the frequency threshold, flexible adjustment of the current playing volume can be realized.

In the case that the electronic device is a bluetooth headset, fig. 2 is a schematic flow chart of determining a playing volume and adjusting an association set of the bluetooth headset according to an embodiment of the present application. As shown in fig. 2, the process may include the steps of:

step 201, collecting current ambient noise amplitude xt according to a specified time interval, and if the difference between xt and historical noise amplitude is greater than a preset difference value, updating the playing volume.

For example, if the difference between xt and the historical noise amplitude is less than or equal to a predetermined difference, the play volume may not be updated.

Illustratively, the current environmental noise may be the current environmental state in the foregoing embodiment.

Illustratively, the difference between xt and the historical noise amplitude is greater than the predetermined difference, which may indicate that the degree of difference between the current environmental parameter and the historical environmental parameter in the foregoing embodiment is greater than or equal to the fourth threshold.

The operation of updating the play volume may exemplarily represent the operation of determining the current play volume in the foregoing embodiment.

Step 202, determining the current playing volume yt.

Illustratively, yt may be the current play volume.

Illustratively, the method may be performed alternatively from the three branches included in step 202, steps 2021 to 2023, according to the relation between the ambient noise amplitude and the current noise amplitude in the relation table; the relationship table may be a set of association relationships between the environment parameters and the play volume in the foregoing embodiment.

For example, before determining the current playing volume, N pieces of associated environmental noise and N playing volumes corresponding to the N pieces of associated environmental noise may be first determined from the relation table based on the current noise amplitude xt, and a fitting relation between the N pieces of associated environmental noise and the N pieces of playing volumes, that is, the volume fitting policy in the foregoing embodiment may be determined.

Illustratively, a magnitude relation between the current noise magnitude and the N associated ambient noises may be determined, and according to the magnitude relation, an execution is selected from steps 2021 to 2023 to determine the current play volume.

Illustratively, in steps 2021 to 2023, an exemplary explanation will be given with the value of N being 2.

Step 2021, if xjl +.xt < xj2 exists, determining yt based on the first distribution state and the relationship table.

Illustratively, the first distribution state may represent xjl +.xt < xj2.

Illustratively, j may be an integer greater than or equal to 0.

For example, yt may be determined based on the first distribution state and a volume fitting strategy determined based on the relationship table.

Illustratively, in the first distribution state, the fitting relationship characterized by the volume fitting strategy can be represented by the functional representation as shown in equation (1):

y＝(x-xj1)*(yj2-yj1)/(xj2-xjl)+yjl (1)

where x may represent a continuously distributed noise amplitude within the interval [ xjl, xj2 ]; y may be a continuously distributed play volume corresponding to x.

Illustratively, substituting xt into equation (1) yields yt having the value of (xt-xj 1)/(xj 2-yj 1)/(xj 2-xjl) + yjl.

Step 2022, if xj1 is less than or equal to xj2 is less than or equal to xt, determining yt based on the second distribution state and the relationship table.

For example, the second distribution state may represent xj 1. Ltoreq.xj2. Ltoreq.xt, where the environmental noise magnitudes in the relationship table may represent that both are less than the current noise magnitude.

Illustratively, in the second distribution state, the volume fitting strategy can be represented by equation (2):

y＝(x-xj2)*(yj2-yj1)/(xj2-xj1)+yj2 (2)

Where x may represent a noise amplitude greater than xj2 outside the interval [ xjl, xj2], and y may be a continuously distributed playback volume corresponding to x.

Illustratively, substituting xt into equation (2) yields yt having the value of (xt-xj 2)/(xj 2-xj 1) +yj2.

Step 2023, if xt is less than or equal to xjl is less than or equal to xj2, determining yt based on the third distribution state and the relationship table.

For example, the third distribution state may represent xt.ltoreq. xjl.ltoreq.xj2, where the environmental noise magnitudes in the relationship table may represent that all are greater than the current noise magnitude.

Illustratively, in the third distribution state, the volume fitting strategy may be represented by equation (3):

y＝yj1-(xjl-x)*(yj2-yj1)/(xj2-xjl) (3)

where x may represent noise amplitude outside the interval [ xjl, xj2] that is smaller than any one of the continuous distributions of xj1, and y may be the continuous distribution of playback volume corresponding to x.

Illustratively, substituting xt into equation (3) yields yt having a value of yj1- (xjl-xt) ×yj2-yj 1)/(xj 2-xjl.

Through any of steps 2021 to 2023, the current play volume corresponding to the current ambient noise amplitude may be automatically determined.

For example, if the volume adjustment operation is collected after the current playing volume is determined, the current playing volume may be adjusted based on the adjustment amplitude corresponding to the volume adjustment operation, so as to obtain a volume adjustment result.

Illustratively, after determining the current playing volume or volume adjustment result, an alternative execution may be performed from step 203 to step 205.

In step 203, in a predetermined time, the difference between the current noise amplitude and the historical noise amplitude is within a predetermined range, and the current playing volume is adjusted to update the relation table.

Illustratively, the volume adjustment result obtained after the current play volume is adjusted may be the same as or different from the historical play volume in the relationship table.

The predetermined time may be, for example, a preset time interval.

Illustratively, the predetermined range may include at least one of a degree of difference between parameters in the set of environmental parameters in the foregoing embodiment being greater than or equal to a first threshold value, and a degree of difference between the current environmental parameter and the historical environmental parameter being greater than or equal to a fourth threshold value.

For example, the current noise amplitude and the adjusted current playing volume may be associated to obtain an association result, and based on the method provided in the foregoing embodiment, the association relationship to be updated is determined from the relationship table, and then the association relationship to be updated is replaced by the association result, so as to update the relationship table.

Illustratively, if it is determined that the current play volume is not adjusted, step 204 is performed.

Step 204, in a predetermined time, the difference between the current noise amplitude and the historical noise amplitude is within a predetermined range, and the relation table is updated.

For example, the current noise amplitude and the current playing volume may be associated to obtain an association result, and based on the method provided in the foregoing embodiment, the association relationship to be updated is determined from the relationship table, and then the association relationship to be updated is replaced by the association result, so as to update the relationship table.

In step 205, the difference between the current noise amplitude and the historical noise amplitude is not within the predetermined range within the predetermined time, and the relation table is not updated.

For example, the difference between the current noise amplitude and the historical noise amplitude is not within the predetermined range, which may indicate that the variation amplitude of the noise amplitude is not large in the period range including the predetermined time, at which time the relation table may not be updated.

After any of steps 203 to 205 is completed, step 201 may be circularly performed, so as to implement real-time determination and adjustment of play volume and flexible update of the relationship table.

According to the embodiment, the method and the device can realize targeted and accurate adjustment of the current playing volume of the Bluetooth headset automatically, intelligently and controllably, and can respond to the adjustment operation of a user in the adjustment process, so that a volume adjustment mode of man-machine interaction on the basis of automation and intellectualization is provided; meanwhile, after the current playing volume is determined or adjusted, the relation table can be automatically updated and optimized in a targeted and controllable manner according to the relation between the current noise amplitude and the historical noise amplitude, so that the determining process of the playing volume can be optimized in the process of determining the playing volume at the future time through the updated relation table, and the playing volume can meet the actual playing requirement. Under the condition of responding to the user volume adjustment requirement, the user requirement and the current noise are also associated and recorded in the relation table, better interpersonal interaction can be realized in the process, the equipment is enabled to know the actual user requirement, namely, the user habit is continuously recorded, the intelligent voice volume adjustment is carried out on the electronic equipment based on the user habit, and the probability that the intelligent tuning process is separated from the actual requirement of the user can be effectively reduced.
