The volume adjustment voice data is voice data containing a volume adjustment direction, and can be voice spoken by a user collected by a microphone of the kitchen electrical equipment or transmitted to the kitchen electrical equipment after voice spoken by the user is collected by a microphone of remote control equipment corresponding to the kitchen electrical equipment. The volume adjustment request is generated by the remote control device according to the operation of the user when the user instructs the kitchen electrical equipment to adjust the volume through the remote control device, and the remote control device sends the volume adjustment request to the kitchen electrical equipment to instruct the kitchen electrical equipment to adjust the volume. The volume adjustment operation is the operation that the user clicks, presses and the like based on a control interface or a control key on the kitchen electrical equipment.

And when a volume adjustment request carrying a volume adjustment direction sent by the remote control equipment is received, triggering a volume adjustment instruction. The practical scene is illustrated as follows: when the kitchen electrical equipment used by a user is an electric oven, the user opens the electric oven to bake food, after the electric oven is baked, voice prompt can be performed, the user is far away from the electric oven, the situation that the volume of the voice prompt is small is avoided, the voice prompt sent out when baking is completed cannot be heard, the volume adjusting request sent by the remote control equipment (the remote control equipment can be a smart phone) carries the volume adjusting direction, and when the kitchen electrical equipment receives the volume adjusting request sent by the remote control equipment and carries the volume adjusting direction, the volume adjusting instruction is triggered. The method for sending the volume adjustment request carrying the volume adjustment direction through the remote control device (the remote control device may be a smart phone) may be based on a control on the mobile phone to send the volume adjustment request carrying the volume adjustment direction; the voice data containing the volume increase can be collected through a microphone of the mobile phone, and when the mobile phone recognizes that the semantic result of the volume increase is obtained through voice recognition, a volume adjustment request carrying a volume adjustment direction is sent.
In step S240, the current volume value is analyzed based on the preset volume interval, and the volume interval to which the current volume value belongs is determined.
Wherein, the volume scope of presetting volume interval is according to the volume scope of speaker in advance, divides the volume scope into a plurality of volume intervals, divides this volume scope into a plurality of volume intervals according to complete machine running noise and the sensitive degree of people's ear to different volumes, for example: the sensitivity level of human ear to different sound pressures is: 0dB-20 dB: weak, breathing sound of oneself; 20dB-40 dB: light, the watch sways; 40dB-60 dB: generally, dialogue sounds; 60dB-80 dB: sounding, speaking sound; 80dB-100 dB: loud, machine tool sound; 100-120 dB: deafness due to earthquake, car horn sound; 120dB-140 dB: intolerable, aircraft engine noise; the range of noise volume (expressed by sound pressure) of the range hood during operation is 47 dB-58 dB, the maximum volume of the range hood is assumed to be 95dB, the minimum volume is assumed to be 15dB, and the preset volume interval can be divided into: 15dB-40dB, 41dB-50dB, 51dB-60dB, 61dB-80dB and 81dB-95dB, and 5 volume intervals are total. The volume interval to which the current volume value belongs is which volume interval the current volume value belongs to, such as: the preset volume interval includes: 15dB-40dB, 41dB-50dB, 51dB-60dB, 61dB-80dB, 81dB-95dB, the current volume value is 52dB, and the volume interval to which the current volume value belongs is 51dB-60 dB.
Step S260, based on different adjustment modes corresponding to different volume intervals, analyzing according to the volume interval to which the current volume value belongs, and obtaining a volume change value.
The different adjusting modes corresponding to the different volume intervals are different modes of correspondingly determining the volume change values of the different volume intervals, and the correspondingly determined volume change values are different.
In one embodiment, analyzing the volume interval to which the current volume value belongs based on different adjustment modes corresponding to different volume intervals to obtain a volume change value includes: acquiring volume adjusting parameters corresponding to the volume intervals based on different adjusting modes corresponding to the different volume intervals; and obtaining a volume change value according to the volume adjusting parameter corresponding to the volume interval.
Wherein, the volume change value is the volume value which needs to be increased or decreased by dB on the basis of the current volume value. The volume adjusting parameters are parameters used for determining the volume change value required to be adjusted currently, different volume intervals correspond to different volume adjusting parameters, the volume adjusting parameters corresponding to the volume intervals can be predetermined according to the sensitivity of human ears to different volumes, and the volume adjusting parameters corresponding to the volume intervals are correlated in advance. And determining the volume adjusting parameter corresponding to the volume interval according to the volume interval to which the current volume value belongs and the volume adjusting parameter associated with the volume interval.
Volume adjusting parameters corresponding to each volume interval are predetermined according to the sensitivity of human ears to different volumes, volume adjusting parameters corresponding to each volume interval are predetermined by adopting a combination mode of different percentage adjustment and fixed value adjustment according to each volume interval, and the following steps are exemplified (the specific volume adjusting parameters are determined based on the user experience research values in actual operation): the preset volume interval includes: 15dB-40dB, 41dB-50dB, 51dB-60dB, 61dB-80dB, 81dB-95dB, based on the human ear when the volume is less than 40dB, the volume is finely tuned, the human ear induction is not very sensitive, and similarly when the volume is greater than 80dB, the volume is finely tuned, the human ear induction is not very sensitive, the volume adjusting parameter corresponding to each volume interval is set as: 15dB-40dB, the corresponding volume adjusting parameters are as follows: adjusting 30% of the current volume value; 41dB-50dB, the corresponding volume adjusting parameters are as follows: adjusting 20% of the current volume value; 51dB-60dB, the corresponding volume adjusting parameters are as follows: adjusting 10% of the current volume value; 61dB-80dB, the corresponding volume adjustment parameters are: adjusting 7% of the current volume value; 81dB-95dB, the corresponding volume adjusting parameters are as follows: increase or decrease by 5dB, etc.
Volume adjusting parameters corresponding to the volume intervals can be predetermined in different percentage adjusting modes according to the volume intervals, for example (the specific volume adjusting parameters are determined based on the user experience research values in actual operation): the preset volume interval includes: 15dB-40dB, 41dB-50dB, 51dB-60dB, 61dB-80dB, 81dB-95dB, based on the human ear when the volume is less than 40dB, the volume is finely tuned, the human ear induction is not very sensitive, and similarly when the volume is greater than 80dB, the volume is finely tuned, the human ear induction is not very sensitive, the volume adjusting parameter corresponding to each volume interval is set as: 15dB-40dB, the corresponding volume adjusting parameters are as follows: adjusting 30% of the current volume value; 41dB-50dB, the corresponding volume adjusting parameters are as follows: adjusting 20% of the current volume value; 51dB-60dB, the corresponding volume adjusting parameters are as follows: adjusting 10% of the current volume value; 61dB-80dB, the corresponding volume adjustment parameters are: adjusting 7% of the current volume value; 81dB-95dB, the corresponding volume adjusting parameters are as follows: adjust 5% of the current volume value, and so on.
Volume adjusting parameters corresponding to each volume interval can be predetermined in a different fixed value adjusting mode according to each volume interval, for example (the specific volume adjusting parameters are determined based on the user experience research values in actual operation): the preset volume interval includes: 15dB-40dB, 41dB-50dB, 51dB-60dB, 61dB-80dB, 81dB-95dB, based on the human ear when the volume is less than 40dB, the volume is finely tuned, the human ear induction is not very sensitive, and similarly when the volume is greater than 80dB, the volume is finely tuned, the human ear induction is not very sensitive, the volume adjusting parameter corresponding to each volume interval is set as: 15dB-40dB, the corresponding volume adjusting parameters are as follows: 13 dB; 41dB-50dB, the corresponding volume adjusting parameters are as follows: 9 dB; 51dB-60dB, the corresponding volume adjusting parameters are as follows: 5.5dB of the current volume value is adjusted; 61dB-80dB, the corresponding volume adjustment parameters are: adjusting 4.55dB of the current volume value; 81dB-95dB, the corresponding volume adjusting parameters are as follows: adjust 4.25dB for the current volume value, and so on.
In one embodiment, obtaining the volume change value according to the volume adjustment parameter corresponding to the volume interval includes: when the volume adjusting parameter is a percentage, analyzing according to the volume adjusting parameter and the current volume value to determine a volume change value; when the volume adjustment parameter is a volume value, the volume value is taken as a volume change value.
When the volume adjusting parameters are percentages, the corresponding volume change values need to be calculated according to the percentages in the volume adjusting parameters, taking the current volume value as 52dB, the volume interval to which the current volume value belongs as 51dB-60dB, and the volume adjusting parameters corresponding to the volume interval as 51dB-60dB as an example for adjusting 10% of the current volume value: the volume change value is: 52dB 10%, i.e., the volume change value is 5.2 dB. When the volume adjustment parameter is a volume value, the volume value is a volume variation value, such as: taking the current volume value as 81dB, the volume interval to which the current volume value belongs is 81dB-95dB, and the volume adjusting parameter corresponding to the volume interval of 81dB-95dB is 5dB for adjusting the current volume value as an example: the volume change value is 5 dB.
In step S280, the current volume value of the speaker is changed by the volume change value in the volume adjustment direction according to the volume change value, so that the speaker responds with the changed volume value.
And the control module of the kitchen electrical equipment adjusts the potentiometer connected with the loudspeaker according to the determined volume change value, so that the current volume value of the loudspeaker changes the volume change value in the volume adjusting direction. The changed volume value is the volume value when the loudspeaker makes a sound after the control module adjusts the potentiometer connected with the loudspeaker according to the determined volume change value. Taking the volume adjusting direction as the volume increase, the current volume value is 52dB, and the volume change value is 5.2dB as an example, the control module of the kitchen electrical equipment adjusts the potentiometer connected with the loudspeaker, so that the current volume value of the loudspeaker is increased by 5.2dB, the changed volume value is 57.2dB, and the loudspeaker responds with the volume value of 57.2 dB.
In one embodiment, changing the current volume value of the speaker by the volume change value in the volume adjustment direction according to the volume change value includes: when the volume adjusting direction is volume increase, the current volume value of the loudspeaker is increased by a volume change value according to the volume change value; and when the volume adjusting direction is volume reduction, reducing the current volume value of the loudspeaker by a volume change value according to the volume change value.
Wherein, the user only needs to show the volume adjustment direction in the volume adjustment instruction, namely: and increasing the volume or reducing the volume, wherein the control module of the kitchen electrical equipment can automatically determine the volume change value according to the current volume value, so that the volume of the loudspeaker is adjusted according to the volume change value. When the volume adjusting direction is volume increase, increasing the current volume value of the loudspeaker by a volume change value according to the determined volume change value; and when the volume adjusting direction is volume reduction, reducing the current volume value of the loudspeaker by the volume change value according to the determined volume change value.

In an embodiment, a method for adjusting the speaker volume of a kitchen electrical appliance is provided, for example, the method for adjusting the speaker volume of a kitchen electrical appliance is applied to a range hood as shown in fig. 4, where the range hood includes a microphone, a speaker and a controller module, and the range hood may further include a bluetooth module and/or a WIFI module for illustration.
The volume range is divided into a plurality of volume intervals according to the running noise of the whole machine and the sensitivity of human ears to different volumes. Such as: the sensitivity level of human ear to different sound pressures is: 0dB-20 dB: weak, breathing sound of oneself; 20dB-40 dB: light, the watch sways; 40dB-60 dB: generally, dialogue sounds; 60dB-80 dB: sounding, speaking sound; 80dB-100 dB: loud, machine tool sound; 100-120 dB: deafness due to earthquake, car horn sound; 120dB-140 dB: intolerable, aircraft engine noise; the range of noise volume (expressed by sound pressure) of the range hood during operation is 47 dB-58 dB, the maximum volume of the range hood is assumed to be 95dB, the minimum volume is assumed to be 15dB, and the preset volume interval can be divided into: 15dB-40dB, 41dB-50dB, 51dB-60dB, 61dB-80dB and 81dB-95dB, and 5 volume intervals are total.
Based on the fact that the volume is slightly changed when the volume is larger or smaller, the volume change cannot be recognized by human ears, so that the volume change is larger, the volume value which a user wants to adjust can be reached as soon as possible, and in the volume range which is sensitive to the user, for example, m is more than 50dB and less than or equal to 60dB, the user can obviously feel the change of the volume when slightly adjusting the time, so the set change is smaller, and the user does not miss the volume value which the user wants because the volume change is larger:
setting the volume adjusting parameter corresponding to each volume interval as follows: 15dB-40dB, the corresponding volume adjustment parameter q1 is: adjusting 30% of the current volume value; 41dB-50dB, the corresponding volume adjusting parameter q2 is: adjusting 20% of the current volume value; 51dB-60dB, the corresponding volume adjusting parameter q3 is: adjusting 10% of the current volume value; 61dB-80dB, the corresponding volume adjustment parameter q4 is: adjusting 7% of the current volume value; 81dB-95dB, the corresponding volume adjustment parameter p is: increasing or decreasing by 5 dB. Wherein, this volume adjustment parameter is applicable to increasing the volume simultaneously, reduces the volume, if: when the volume interval corresponding to the current volume value is q1, the volume adjustment command for decreasing the volume is corresponding to a volume adjustment parameter q1, and the volume adjustment command for increasing the volume is also corresponding to a volume adjustment parameter q 1.
In one scenario, when a microphone of the range hood collects 'opening the range hood' spoken by a user, a control module of the range hood controls to open the range hood and then controls a loudspeaker to respond with a current volume value: "you have opened the extractor hood for you". The user is in cooking, and voice control range hood opens the well shelves, and range hood's control module control is opened range hood and is opened well shelves to control the speaker and answer with current volume value: "you have opened mid range" when the speaker volume m is 45 dB. The sudden user feels that the middle-grade air quantity is too small, the voice control range hood opens a large grade, the control module of the range hood controls the range hood to open and open the large grade, and the loudspeaker is controlled to respond by the current volume value loudspeaker: "have opened the big file for you". At this time, the noise of the range hood is increased, but the volume m of the loudspeaker is still 45dB, and the user feels that the volume is small and needs to increase the volume. At the moment, the volume is in a volume interval with the volume more than 41dB and less than or equal to 50dB, and the corresponding volume adjusting parameters are as follows: adjusting 20% of the current volume value increases the volume once in 9dB, the speaker and responds: "volume has been increased for you". The volume of the loudspeaker is 54dB after the volume is increased, and the user feels that the sound can be adjusted.
In one scene, a user can boil noodles while opening the range hood and cut cold dishes while cooking. At the moment, when a user wants to listen to music, the range hood is controlled by voice to order a song, the song of 'make the world love China make' is played, the volume of the loudspeaker is 45dB, and the user feels that the volume is small in an interval of more than 40dB and less than or equal to 50dB, and needs to increase the volume. At the moment, the volume is in a volume interval with the volume more than 41dB and less than or equal to 50dB, and the corresponding volume adjusting parameters are as follows: the playing volume of one song is increased by 9dB by adjusting 20% of the current volume value, the volume of the loudspeaker is 54dB playing after being increased, and the sound felt by a user can be adjusted; similarly, if the user wants to reduce the volume, the playback volume of a song is reduced by 9 dB.
The method for adjusting the volume of the loudspeaker of the kitchen electrical equipment can avoid the problems that when the current volume is larger or smaller, the volume is slightly changed, the change of the volume cannot be identified by human ears, and the volume value expected by a user cannot be quickly adjusted, and the user can obviously feel the change of the volume within the sensitive volume range of the user, such as m is more than 50dB and less than or equal to 60dB when the volume is slightly adjusted, so the set variable quantity is smaller, and the volume value expected by the user cannot be missed because the volume change is larger.
