Based on the above mobile terminal hardware structure and the communication network system, various embodiments of the method of the present application are provided.
Fig. 3 is a flowchart of an embodiment of a volume adjustment method provided by the present application. Once triggered by the user, the process in this embodiment is automatically executed by the mobile terminal 100, where each step may be executed sequentially as shown in the flowchart, or may be executed simultaneously according to the actual situation, and this is not limited herein. The volume adjusting method provided by the application comprises the following steps:
step S310, detecting broadcast data around the mobile terminal in real time when the mobile terminal 100 is in an audio data output state;
step S330, extracting an ultrasonic signal in the broadcast data;
step S350 of determining a notification level of the broadcast data based on the ultrasonic signal;
Step S370, determining an audio data output strategy of the mobile terminal 100 according to the notification level of the broadcast data;
step S390 adjusts the volume of the mobile terminal 100 outputting the audio data based on the audio data output policy.
With the above embodiment, when the mobile terminal 100 is in an audio data output state, broadcast data around the mobile terminal 100 is first detected in real time; then extracting ultrasonic signals in the broadcast data; further determining a notification level of the broadcast data based on the ultrasonic signal; further, determining an audio data output policy of the mobile terminal 100 according to the notification level of the broadcast data; finally, the volume of the audio data output by the mobile terminal 100 is adjusted based on the audio data output policy, so that the notification level of the broadcast data can be determined based on the ultrasonic signal in the broadcast data, and the volume of the audio data output by the mobile terminal 100 is adjusted according to the notification level of the broadcast data, thereby avoiding the neglect of the broadcast data.
The above steps will be specifically described with reference to specific embodiments.
In step S310, when the mobile terminal 100 is in an audio data output state, broadcast data around the mobile terminal 100 is detected in real time.
In this embodiment, the surrounding may refer to that the mobile terminal 100 is preset within an effective range. The preset valid range may refer to a maximum range in which the mobile terminal 100 can detect broadcast data. The broadcast data may be played by a playback device coupled to the broadcast device. The playing device can be one or more of a sound box and a loudspeaker.
In this embodiment, the mobile terminal 100 may detect broadcast data around the mobile terminal 100 in real time when the mobile terminal 100 is in an audio data output state. For example, when a headset is connected to the mobile terminal 100 through a USB interface of the mobile terminal 100 and a user listens to the audio data through the headset, the mobile terminal 100 may detect broadcast data around the mobile terminal 100 in real time. When the mobile terminal 100 externally emits the audio data through its own speaker, the mobile terminal 100 may also detect the broadcast data around the mobile terminal 100 in real time.
In step S330, an ultrasonic signal in the broadcast data is extracted.
In this embodiment, the broadcasting apparatus may include an ultrasonic generator that may generate a corresponding ultrasonic signal according to the notification level. The frequency of the ultrasonic signal may be a preset frequency, which may be set in advance, for example, 24khz, which is not limited herein.
In this embodiment, the broadcast data may be formed by mixing the ultrasonic signal and the sound to be played. After detecting the broadcast data, the mobile terminal 100 may extract the ultrasonic signal in the broadcast data, so that a notification level of the broadcast data may be determined based on the ultrasonic signal in a subsequent step.
In step S350, a notification level of the broadcast data is determined based on the ultrasonic signal.
In this embodiment, the notification level may refer to an importance level of the broadcast data. The notification level may include a first level, a second level, and a third level. It will be appreciated that in other embodiments, the notification level may also include a greater variety of importance levels.
In this embodiment, the step of determining the notification level of the broadcast data based on the ultrasonic signal includes:
step S3501 of determining, when the broadcast data does not contain the ultrasonic signal, that the notification level of the broadcast data is the first level;
step S3502, when the broadcast data includes an ultrasonic signal having a frequency of a preset frequency and a duration of a first duration, determining that a notification level of the broadcast data is the second level;
Step S3503, when the broadcast data contains an ultrasonic signal with a frequency of the preset frequency and a duration of a second duration, determining that the notification level of the broadcast data is the third level;
wherein the first duration is less than the second duration.
In this embodiment, the importance level of the first level is smaller than the importance level of the second level, and the importance level of the second level is smaller than the importance level of the third level. The first time period is less than the second time period, for example, the first time period is 100ms, and the second time period is 200ms.
In this embodiment, taking the preset frequency of 24khz, the first duration of 100ms, and the second duration of 200ms as an example, when the broadcast data does not include the ultrasonic signal, the mobile terminal 100 may determine that the notification level of the broadcast data is the first level; when the broadcast data includes an ultrasonic signal having a frequency of 24khz and a duration of 100ms, the mobile terminal 100 may determine that a notification level of the broadcast data is the second level; when the broadcast data includes an ultrasonic signal having a frequency of 24khz and a duration of 200ms, the mobile terminal 100 may determine that the notification level of the broadcast data is the third level. That is, the notification level of the broadcast data may be higher as the duration of the ultrasonic signal included in the broadcast data is longer.
In step S370, an audio data output policy of the mobile terminal 100 is determined according to the notification level of the broadcast data.
In this embodiment, the volume adjustment method further includes:
step S3701, constructing a mapping relationship between the notification level and the audio data output policy, where the mapping relationship between the notification level and the audio data output policy is a one-to-one correspondence.
In this embodiment, the audio data output policy may include a first audio data output policy, a second audio data output policy, and a third audio data output policy. The first audio data output policy, the second audio data output policy, and the third audio data output policy may be different from each other. The first notification level may correspond to the first audio data output policy; the second notification level may correspond to the second audio data output policy; the third notification level may correspond to the third audio data output policy.
It will be appreciated that in other embodiments, the audio data output policy may also include a greater variety of policies. The number of audio data output policies may be the same as the number of notification levels. For example, the notification level may include a first notification level, a second notification level, a third notification level, and a fourth notification level, and the audio data output policy may include a first audio data output policy, a second audio data output policy, a third audio data output policy, and a fourth audio data output policy, respectively.
In this embodiment, the step of determining the audio data output policy of the mobile terminal according to the notification level of the broadcast data includes:
step S3702, searching the mapping relation to determine an audio data output policy of the mobile terminal 100 corresponding to the notification level.
In this embodiment, the mobile terminal 100 may construct a mapping relationship between the notification level and the audio data output policy, so that the mapping relationship may be searched to determine the audio data output policy of the mobile terminal 100 corresponding to the notification level, and then the volume of the mobile terminal 100 outputting the audio data may be adjusted based on the audio data output policy in a subsequent step, so that different audio data output policies of the mobile terminal 100 may be determined according to the notification level of the broadcast data.
For example, when the broadcast data does not include the ultrasonic signal, the mobile terminal 100 may determine that the notification level of the broadcast data is the first level, and then may search the mapping relationship according to the first level to determine a first audio data output policy of the mobile terminal 100 corresponding to the first notification level. When the broadcast data includes an ultrasonic signal having a frequency of 24khz and a duration of 100ms, the mobile terminal 100 may first determine that a notification level of the broadcast data is the second level; a second audio data output policy of the mobile terminal 100 corresponding to the second notification level may then be determined based on the second level lookup mapping. When the broadcast data includes an ultrasonic signal having a frequency of 24khz and a duration of 200ms, the mobile terminal 100 may first determine that a notification level of the broadcast data is the third level; and then a third audio data output policy of the mobile terminal 100 corresponding to the third notification level may be determined by looking up the mapping relation according to the third level.
In step S390, the volume at which the mobile terminal 100 outputs the audio data is adjusted based on the audio data output policy.
In this embodiment, the step of adjusting the volume of the audio data output by the mobile terminal 100 based on the audio data output policy includes:
step S3901 of controlling the mobile terminal 100 to output the audio data at a first volume based on the first audio data output policy; or (b)
Step S3902 of controlling the mobile terminal 100 to output the audio data at a second volume based on the second audio data output policy; or (b)
Step S3903 of controlling the mobile terminal 100 to output the audio data at a third volume based on the third audio data output policy;
the first volume is an original volume, the first volume is larger than the second volume, and the second volume is larger than the third volume.
In this embodiment, the sound volumes may include a first sound volume, a second sound volume, and a third sound volume. The second volume may be 40%, 60% of the original volume, etc., without limitation. The third volume may be 20%, 10%, 0% of the original volume, etc., and is not limited herein.
It will be appreciated that in other embodiments, the first volume may be less than the original volume, such as, for example, the first volume may be 90%, 80%, etc. of the original volume, which is not limited herein. The volume of the mobile terminal 100 outputting the audio data may include more kinds, and the number of volumes of the mobile terminal 100 outputting the audio data may be the same as the number of audio data output strategies. For example, the audio data output policies include a first audio data output policy, a second audio data output policy, a third audio data output policy, and a fourth audio data output policy, and the volumes may include a first volume, a second volume, a third volume, and a fourth volume, respectively.
In other embodiments, the first volume may also be greater than the original volume, for example, the first volume may be 110%, 120%, etc. of the original volume, which is not limited herein. In this way, when the broadcast data is not important, the volume at which the mobile terminal 100 outputs the audio data can be increased, avoiding interference by the broadcast data.
In this embodiment, the mobile terminal 100 may control the mobile terminal 100 to output the audio data at a first volume based on the first audio data output policy; or controlling the mobile terminal 100 to output the audio data at a second volume based on the second audio data output policy; or controls the mobile terminal 100 to output the audio data at a third volume based on the third audio data output policy, so that the volume at which the mobile terminal 100 outputs the audio data can be adjusted according to the notification level of the broadcast data. That is, when the duration of the ultrasonic signal included in the broadcast data is longer, the notification level of the broadcast data may be higher, and the volume of the audio data output by the mobile terminal 100 may be lower, so that the user may be prevented from missing important broadcast data, and the user experience is improved.
For example, the first volume is the original volume, the second volume is 40% of the first volume, i.e., 40% of the original volume, and the third volume may be zero. When the broadcast data does not include the ultrasonic signal, the mobile terminal 100 may determine that a notification level of the broadcast data is the first level and an audio data output policy of the mobile terminal 100 is the first audio data output policy, so that the mobile terminal 100 may be controlled to continue outputting the audio data at an original volume based on the first audio data output policy. When the broadcast data includes an ultrasonic signal having a frequency of 24khz and a duration of 100ms, the mobile terminal 100 may determine that the notification level of the broadcast data is the second level and the audio data output policy of the mobile terminal 100 is the second audio data output policy, so that the mobile terminal 100 may be controlled to continue outputting the audio data at 40% of the original volume based on the second audio data output policy, at which time both the broadcast data and the audio data may be heard by the user. When the broadcast data includes an ultrasonic signal having a frequency of 24khz and a duration of 200ms, the mobile terminal 100 may determine that the notification level of the broadcast data is the third level the audio data output policy of the mobile terminal 100 is the third audio data output policy, so that the mobile terminal 100 may be controlled to continue outputting the audio data at 0% of the original volume, that is, output the audio data in a mute form based on the third audio data output policy,
That is, the volume at which the mobile terminal 100 outputs the audio data may not be changed when the notification level is the first level. When the notification level is the second level, the volume at which the mobile terminal 100 outputs the audio data may be reduced. When the notification level is a third level, the mobile terminal 100 mutes the audio data.
In this embodiment, when the notification level of the broadcast data is lower, the volume of the audio data output by the mobile terminal 100 may be higher or even keep the original volume, and when the notification level of the broadcast data is higher, the volume of the audio data output by the mobile terminal 100 is lower or even zero, so that it is avoided that the user omits surrounding important broadcast data due to the output of the audio data by the mobile terminal 100, and the use experience of the user is improved.
With the above embodiment, when the mobile terminal 100 is in an audio data output state, broadcast data around the mobile terminal 100 is detected in real time; extracting an ultrasonic signal in the broadcast data; determining a notification level of the broadcast data based on the ultrasonic signal; determining an audio data output policy of the mobile terminal 100 according to the notification level of the broadcast data; the volume of the mobile terminal 100 outputting the audio data is adjusted based on the audio data output policy, so that the notification level of the broadcast data can be determined based on the ultrasonic signal in the broadcast data, and the volume of the mobile terminal 100 outputting the audio data can be adjusted according to the notification level of the broadcast data.
