Because the corresponding scale tables of the bluetooth headset device 200b are consistent when the bluetooth headset device leaves the factory, not only the operating systems of the electronic device are different, but also the bluetooth output power corresponding to the electronic device is different, which causes the volume of the bluetooth headset device 200b to be different when the bluetooth headset device is collocated with different operating systems, sometimes the volume is too large, sometimes the volume is too small, and the user experience is not high.

In the third section, the scope of protection of the claims disclosed in the embodiments of the present application is described below.
Referring to fig. 3, fig. 3 is a schematic flow chart of a parameter adjusting method applied to a first device according to an embodiment of the present application.
S301, under the condition that the first device establishes communication connection with the second device, receiving a device identifier sent by the second device.
The first device may be a bluetooth headset device, and may establish a communication connection with a second device (terminal device) through a bluetooth apparatus. The communication connection request may be initiated by bluetooth or wirelessly, and the specific details are not limited herein.
After the first device is successfully connected with the second device in a communication manner, a device identifier acquisition request is triggered to be initiated to the second device so as to acquire the device identifier of the second device. Of course, the first device may also actively send the device identifier to the first device after the communication connection with the second device is successful, and the first device may receive the device identifier sent by the second device.
The device identifier refers to a device identifier of the second device, and the device identifier may be used to indicate a device type of the second device.
Optionally, the device type may be used to indicate an operating system of the first device, and specifically may include any one of the following: an IOS operating system, an Android operating system, and a Windows operating system, etc., which are not limited herein.
It should be noted that the device type may be used to indicate not only the operating system, but also the device model of the first device, and the like, and is not limited herein.
S302, the first device adjusts an EQ parameter according to the device identifier, wherein the EQ parameter is used for indicating that volume adjustment is achieved on the first device.
The EQ (equalizer) parameters may refer to sound used for adjusting the audio data transmitted from the second device, and may be specifically used for adjusting tone, volume, and the like. In the embodiment of the present application, the EQ parameter is mainly used for adjusting the output volume of the audio data.
The first device can store an initial scale table and a volume gear table, the initial scale table stores a plurality of initial scales, the volume gear table stores a plurality of volume gears, and each initial scale can correspond to one volume gear; the initial scale table may refer to a scale table configured when the first device leaves a factory, or may refer to a scale table when the first device is used last time, which is not limited herein. The adjustment of the initial scale table can be realized by adjusting the subsequent EQ parameters so as to obtain the target scale table. Volume adjustment for the first device may be achieved through the target scale table.
Optionally, if the first device is not used for the first time, in a specific implementation of the adjusting the EQ parameter according to the device identifier, the first device may determine whether the device identifier changes compared to the previous time, and if so, may perform the adjustment of the EQ parameter.
For example, if the first device establishes a communication connection with the second device corresponding to the Android operating system last time, and establishes a communication connection with the device of the IOS operating system at the current time, the first device may adjust the EQ parameter according to the device identifier of the IOS operating system; the initial scale table is a scale table adapted to an Android operating system, after the equipment type is changed from the last equipment type, namely the equipment type is changed from the Android operating system to the IOS operating system, the EQ parameters can be adjusted to adjust the initial scale table to obtain a target scale table, and the volume of the first equipment can be adjusted through the target scale table to enable the volume of the first equipment to be adapted to the equipment of the IOS operating system.
In this embodiment, the adjusting of the EQ parameter may be performed by a first device, and the first device may complete initial configuration of the EQ parameter when the first device leaves a factory.
It should be noted that, the first device may also be adjusted by the second device to obtain result data of the EQ parameter, and send the result data to the first device, and the first device controls the output volume according to the result data.
In one possible example, the EQ parameters include at least one of: frequency location, gain parameters, range, gain/attenuation pattern, etc., without limitation.
The frequency position in the EQ parameters can be used to indicate the parameters of the specific required gain or attenuation frequency position, and the level of the sound range is affected by the parameters. The gain parameter, a parameter indicating a gain (increase) or a fade (decrease) of the volume; the above-mentioned range of pitch ranges can be used to indicate parameters of gain or attenuation range, the smaller the value, the wider the range of pitch ranges; the gain/attenuation mode is used for indicating the effect of changing the volume of a specific frequency and correcting the tone; the gain/attenuation mode may be set by the user or default to the system, and is not limited herein.
In one possible example, the adjusting EQ parameters according to the device identifier may include: if the equipment identifier is empty, adjusting the EQ parameter according to a first preset mode; if the device identifier is not empty, acquiring the device type of the second device, and if the device type indicates a preset device type, adjusting the EQ parameter according to a second preset mode.
The first preset mode and/or the second preset mode may be set by a user or default by a system, which is not limited herein. The first preset manner may be to default to the initial parameters of the EQ parameters, or to adjust the EQ parameters obtained by the last adjustment to the initial parameters.
The preset device type can be set by a user or defaulted by a system, and is not limited herein; the preset device type may include: an IOS operating system, an Android operating system, and a Windows operating system, etc., which are not limited herein. The second preset manner of the EQ parameter may be preset for each device type. The second predetermined manner may be understood as adjusting some or all of the EQ parameters, and the specific manner of adjusting the parameters is not limited herein.
For example, if the volume output by the first device using the initial scale table is smaller for the user corresponding to the second device of the IOS operating system, the volume corresponding to the played audio data is smaller; then, when the preset device type is set as the IOS operating system, and the device identifier indicates that the second device is the IOS operating system, the EQ parameter may be adjusted in a second preset manner, so that the volume of the audio data output by the first device is increased; if the volume output by the first device by using the initial scale table is appropriate for a user corresponding to the second device of the IOS, the volume corresponding to the played audio data is appropriate, and when the device identifier indicates that the second device is the Android operating system, the EQ parameter may not be adjusted.
In a specific implementation, when a field for indicating an equipment identifier is not stored in the second equipment, or the first equipment does not acquire a returned equipment identifier of the second equipment due to the problems of authority and the like, the first equipment may receive or acquire an empty equipment identifier, and at this time, an initial parameter may be adopted by default or a parameter obtained by the last EQ parameter adjustment may be kept; or the EQ parameters obtained by the last adjustment are adjusted to the initial parameters, and the specific adjustment mode can be determined according to the use scene. For example, if it is detected that the communication connection is established with the second device for the first time, the initial parameters may be adopted; and if the location of the second equipment is detected to be inconsistent with the location of the EQ parameter which is adjusted last time, adjusting the EQ parameter obtained by the last adjustment to the initial parameter.
Further, when the device identifier returned by the second device is not null, it indicates that there is a returned device type, such as an operating system type, in the second device, and therefore, according to the device type, a second preset mode matching the device type may be selected, thereby implementing adjustment of the EQ parameter.
It can be seen that, in this example, the operating system of the second device may be identified by the device identifier according to different usage scenarios, and a suitable EQ parameter adjustment manner is adapted according to the operating system and the usage scenarios, which is beneficial to increasing the diversity of the EQ parameter adjustment method, and is beneficial to avoiding that the volume of the first device is too large or too small due to the difference in audio output power corresponding to different devices, and is beneficial to improving user experience.
In one possible example, in a case that the device type indicates a preset device type, the method further includes: acquiring an identification bit of the second device; determining the area where the second equipment is located according to the identification bit; and if the area meets the preset condition, executing the step of adjusting the EQ parameters according to a third preset mode.
The preset condition can be set by the user or defaulted by the system, and is not limited herein; different regions may be constrained by the predetermined condition, for example, if the region is in a relatively noisy area or region, or a more specific region (e.g., a machine room, a kitchen, a mall, a city, etc.), the region may be considered to satisfy the predetermined condition. The third preset mode can be different from the first preset mode and/or the second preset mode, the EQ parameter can be adjusted through different preset modes, the adjustment on the initial scale table is realized through the EQ parameter, and under different conditions, the adjustment strength and the adjustment range on the initial scale table through different preset modes are different; for example, if the second preset mode is to adjust part of the initial scale, and the area where the first device is located is a noisy environment, then the sound heard by the user through the first device is wholly reduced, and all the initial scales can be adjusted through the third preset mode, so that the volume of the first device is wholly increased.
It can be seen that, in this example, for some special areas, the EQ parameter in the first electronic device may be adjusted in time when the second device is in the special area, so as to ensure that the user using the first device can still use the first device normally in the area.
Optionally, in this embodiment of the present application, in different situations when the user uses the first device, the first device may have different execution options in adjusting the EQ parameter, for example: 1) in the foregoing step S301, the communication connection request may be a first connection, in this case, an obtaining instruction for initiating an apparatus identifier obtaining request to the second apparatus may be triggered, and then an apparatus identifier sent by the second apparatus is received, and according to the apparatus identifier, the first apparatus determines whether to perform adjustment of the EQ parameter according to the apparatus identifier, and when the EQ parameter needs to be adjusted, the EQ parameter may be adjusted, and the subsequent steps are not described again; 2) if the communication connection is not the first connection, it is indicated that the equipment identifier of the second equipment is the same as the equipment identifier of the last communication connection, and the area where the second equipment is located does not meet the preset condition, then the EQ parameter adjustment is not needed, the play instruction of the user on the second equipment can be directly responded to, the audio data sent by the second equipment is received, and the play operation of the audio data is realized through the current scale table stored in the first equipment; 3) if the communication connection is not the first connection and the area where the second device is located meets the preset condition, an equipment identifier acquisition request may be initiated to the second device and the equipment identifier corresponding to the second device may be received under the condition that the second device establishes the communication connection, and then the step of adjusting the EQ parameter is performed according to the equipment identifier, and the subsequent steps are not described herein again.
As can be seen, in this example, it is not necessary to determine whether the EQ parameters need to be adjusted every time a communication connection is performed; whether the EQ parameter needs to be adjusted or not can be judged according to whether the first equipment is firstly accessed into the second equipment and the area where the second equipment is located, so that the communication frequency is reduced, and the equipment power consumption of the first equipment is saved; and when the user operates in the second device to play audio data such as music, voice and the like through the first device, the playing efficiency is improved.
Optionally, after the user uses the first device for the first time, i.e., communicates with the second device for the first time, and completes the adjustment of the EQ parameters, the target EQ parameters such as the frequency position, the gain parameter, the range of the vocal range and the like corresponding to the first device in this case may be stored, and a target gain/attenuation mode may be set for the series of parameters, so as to indicate the target EQ parameters such as the frequency position, the gain parameter, the range of the vocal range and the like corresponding to the area or the device.
In specific implementation, when it is detected that the user enters the area satisfying the preset condition again from the area not satisfying the preset condition, the target EQ parameter in the target gain/attenuation mode corresponding to the area may be directly obtained after the first device establishes the communication connection, and the output of the audio data of the first device is completed under the target EQ parameter.
In a possible example, after the obtaining of the device type of the second device, the method may further include: acquiring a target environment parameter under the condition that the equipment type meets a preset equipment type; determining a first target influence factor corresponding to the target environment parameter according to a mapping relation between a preset environment parameter and the first influence factor; acquiring target output power of audio data sent by the second equipment; determining a second target influence factor corresponding to the target output power according to a mapping relation between preset output power and the second influence factor; and adjusting the EQ parameters according to the first target influence factor and the second target influence factor.
Wherein, the target environment parameter may include at least one of the following: geographic location, magnetic field disturbance intensity, wind intensity, stormy weather, etc., without limitation. The mapping relation between the environmental parameter and a first influence factor can be set in the first device, and the first influence factor can be used for representing the influence of various factors in the environment on the sound size of the audio data output by the first device; the first device may further store a mapping relationship between the output power and a second influence factor, where the output power may refer to an output power of the second device sending the audio data to the first device through the communication mode after the second device establishes communication, and the second influence factor may represent an influence of the output power on a sound size of the audio data output by the first device, and specifically, the output power of the audio data output by the second device is different due to different device identifiers corresponding to the second device or different audio output powers set by the second device in different time periods or different areas, or the output power of the audio data output by the second device in different time periods and different areas is different, that is, the output power is different, so that the output sound size of the second device loaded by the first device is different; the second influence factors corresponding to different output power levels are different, for example, the smaller the output power is, the smaller the corresponding second influence factor is. The first and/or second influencing factors may range from (-1, 1).
In a specific implementation, if the target environmental parameter includes n (a plurality, in this application, a plurality may refer to two or more, and is not described herein), each environmental parameter corresponds to one first sub-influence factor biWherein the sum of all the first sub-influence factors is 1, the first sub-influence factor b may beiCorresponding specific parameter a for representing target environment parameteriPerforming cumulative summation, i.e. first target influence factor

Furthermore, due to the different EQ parameters c among the EQ parametersiAffected differently by environmental parameters and output power, and therefore, the first device may further include an influence reference diCan be used for characterizing the environmental parameters and the output power to the EQ parameter ciThe magnitude of the effect of (c); determining a second target influence factor corresponding to the target output power according to a mapping relation between preset output power and the second influence factor; and calculating each EQ parameter c according to the first target influence factor x1, the second target influence factor x2 and the reference influence degreeiImportance evaluation value of (1): y isi＝di(1+ x1) (1+ x 2). Finally, the EQ parameters can be adjusted according to the importance evaluation value corresponding to each EQ parameter; specifically, the first device may include an adjustment table corresponding to each EQ parameter, where the adjustment table includes a plurality of fine-tuning parameters, and if the importance evaluation value corresponding to an EQ parameter is greater than a preset threshold (the preset threshold may be a user-defined threshold)Self-setting or default system, and not limited herein), adjusting the EQ parameter, selecting a fine-tuning parameter matched with the importance evaluation value from an adjustment table, and adjusting an initial parameter of the EQ parameter to obtain an adjusted EQ parameter; and if the importance evaluation value is smaller than or equal to a preset threshold value, not adjusting the importance evaluation value, and keeping the original EQ parameters.
As can be seen, in this example, considering that, in a specific environment scene, the first device is affected by various environmental factors (for example, raining when the user is inclined, windy weather, magnetic field interference, and the like) to cause interference in signal transmission, or the user cannot hear audio data played in the first device due to too much noise in the environment, in this application, the environmental factors and the influence of the output power of the second device on the playing of the first device may be comprehensively considered, which is beneficial to grasping the influence of various parameters on the EQ parameter, and is beneficial to improving the accuracy of the EQ parameter adjustment, and is beneficial to improving user experience. Finally, the importance assessment larger than the preset threshold value can be adjusted when the EQ parameter is adjusted, so that the situation that the volume adjustment span is too large due to the subsequent adjustment according to the EQ parameter is avoided, smoothness of the finally generated target scale is guaranteed, and the situation that the variation amplitude between two volume gears is too high is avoided.
In one possible example, after the receiving the device identifier sent by the second device, the method further includes: acquiring preset volume gears and initial volume corresponding to each volume gear; acquiring an initial scale table, wherein the initial scale table comprises a plurality of initial scales, and each initial scale corresponds to one volume gear; adjusting the plurality of initial scales according to the EQ parameters to obtain a plurality of target scales, and generating a target scale table according to the plurality of target scales, wherein each target scale corresponds to one initial scale; the EQ parameter is used to indicate that volume adjustment is to be implemented for the first device, and may include the following steps: adding each initial volume and a target scale of a corresponding volume gear to obtain a target volume corresponding to each volume gear under the condition that the EQ parameter is used for indicating a first preset gain type; or, when the EQ parameter is used to indicate a second preset gain type, subtracting the target scale of each initial volume from the target scale of the corresponding volume gear to obtain the target volume corresponding to each volume gear.
The first device may preset volume gears for representing volume sizes, the volume gears are different, and the corresponding volume sizes are different, for example, the larger the volume gear is, the larger the corresponding volume size is; the volume level may refer to the volume at which the first device plays audio data sent by the second device. The first device may further comprise an initial scale table used by the user last time the first device is used or pre-stored in advance, and the initial scale table may comprise a plurality of initial scales. The target scale table also includes a plurality of target scales.
The first preset gain type and/or the second preset gain type may be set by a user or default, and is not limited herein. For example, the first predetermined gain type is a negative gain type, and the second predetermined gain type is a positive gain type.
In a specific implementation, the plurality of initial scales may be adjusted according to the plurality of EQ parameters and the scale types (e.g., octave, half-octave, etc.) corresponding thereto to generate a scale effect graph, where the scale effect graph may include a plurality of target scales and specific parameters of each target scale.
Furthermore, because in actual use, the target scale table is influenced by factors such as a noisy environment, and the volume obtained by outputting the output power corresponding to all the volume gears is not influenced by the noisy environment, so that the user cannot hear or hear the sound, the target scale table can be determined according to the actual adjustment condition of each EQ parameter in the EQ parameters, and the target scale table can comprise a target scale for partially or completely adjusting the initial scale; furthermore, the volume corresponding to the changed or actually adjusted target scale and the volume level corresponding to the target scale can be processed to obtain a new volume, i.e. the target volume. Specifically, when the EQ parameter is used to indicate a negative gain, each initial volume may be added to the target scale of the corresponding volume step to obtain a target volume corresponding to each volume step; when the EQ parameter is used to indicate a positive gain, the target volume corresponding to each volume step may be obtained by subtracting the target scale of the corresponding volume step from each initial volume. Further, the adjustment of the actual output volume of the first device is performed in advance.
For example, if the user is in a noisy environment, after the first device is connected to the second device, the user may not hear the volume when adjusting the volume shift to the minimum, and when adjusting the volume shift to the previous shift, if the sound is suddenly increased, there is a large amplification, the user experience is very poor, and smooth adjustment of the volume may be implemented in the embodiment of the present application, as shown in the following table, the mapping relationship between the scale, the volume shift, and the volume is a mapping relationship, where the initial scale corresponding to the target scale Q1.1 is Q1, the initial scale corresponding to the target scale Q1.2 is Q2, except for the target scale Q1.1 and the target scale Q1.2, if no change occurs in other initial scales, the target volume does not need to be adjusted, and only the volume that has a scale change is adjusted.

It can be seen that, in this example, due to the influence of the environmental noise, the influence of the environmental noise on the volumes of different volume gears is different, and a smooth adjustment can be performed on part or all of the initial scale in advance according to the EQ parameter, so as to avoid the problem of sudden and large sound caused by too large variation range between any two volume gears, which is beneficial to improving the user experience.
