The embodiment of the application provides a self-adaptive adjusting method for playing volume of an earphone. The method can be applied to a mobile terminal, and the mobile terminal is connected with an earphone. As shown in fig. 2, the method may include the steps of:
210. and collecting the environmental sound signals in the earphone play mode.
In the embodiment of the application, after the mobile terminal is successfully connected with the wired earphone or the wireless earphone, when multimedia playing (such as listening to music, watching video, playing games, making a call, performing audio/video call, and the like) is performed on the mobile terminal, audio output can be performed through the earphone, and then the mobile terminal enters an earphone playing mode. At this time, the ambient sound signal in the environment where the mobile terminal is located may be collected in real time or at regular time intervals (e.g., 1 second, 1.5 seconds, 2 seconds, 3 seconds, or other values). Specifically, when the earphone connected to the mobile terminal does not have a sound pickup function (i.e., the earphone is not provided with a microphone), one or more microphones built in the mobile terminal may be used to collect the ambient sound signal; when the earphone connected to the mobile terminal is equipped with a sound collecting function (i.e., the earphone is equipped with a microphone), the microphone of the earphone or the microphone of the mobile terminal may be used to collect the ambient sound signal, which is not limited herein.
220. Analyzing the environmental sound signal, determining whether the environmental sound signal includes a preset voice signal, if yes, executing step 230; if not, the operation is ended.
In the embodiment of the application, the mobile terminal can analyze the collected environment sound signal and determine whether the environment sound signal contains the pre-stored preset voice signal. Specifically, the speech recognition may be performed on the environmental sound signal to determine whether the environmental sound signal contains a preset speech signal, and the specific process may be as follows: carrying out noise reduction processing on the environmental sound signal, then extracting characteristic parameter information, matching the characteristic parameter information with a pre-trained voice model library, and if the matching with one of the voice signals in the voice model library is successful, determining that the environmental sound signal contains a preset voice signal; if the environmental sound signal is not matched with all the voice signals in the voice model library, the environmental sound signal can be considered to not contain the preset voice signal. The preset voice signal in the voice model library may be recorded by the user in advance, or may be downloaded from the internet, which is not limited herein. The preset voice signal may include, but is not limited to, some greetings (e.g., "hello", "hi", etc.), the name or nickname of the user (e.g., "zhang san", "alt", etc.), the name of the user (e.g., "lao gong", "wife", "dad", "mom", "son", "girl", etc.), or other commonly used phrases set by the user, etc. If the mobile terminal determines that the preset voice signal exists in the environmental sound signal, the next step 230 may be further performed; if the preset voice signal does not exist in the environment sound signal, the volume adjusting operation can be finished, and the sound signal in the environment is collected continuously.
230. And adjusting the playing volume of the earphone so as to reduce the playing volume of the earphone.
In the embodiment of the application, when the mobile terminal determines that the environmental sound signal contains the preset voice signal, the volume of the earphone playing can be reduced or the earphone playing can be paused. Optionally, the volume played by the headphones may be reduced to a volume V ', where V' is V × δ, V is the current volume played by the headphones (i.e., the volume played before reduction), δ is a low volume coefficient, and δ is a positive number less than 1. For example, if the current playing volume of the headphone is 50 db, and the low volume coefficient δ is 0.6, the adjusted playing volume of the headphone is 30 db. Optionally, the volume played by the headset may be reduced to a preset volume value, where the preset volume value is a fixed value, such as 20 db, 25 db, 30 db, 35 db, or other values. It is understood that the preset volume value can be adaptively adjusted according to the user's needs and/or application scenarios. For example, if the current playing volume of the earphone is 50 db and the preset volume value is 30 db, the adjusted playing volume of the earphone is 30 db. If the playing volume of the current earphone is 60 db, and the preset volume value is 30 db, the adjusted playing volume of the earphone is 30 db.
240. And sending voice prompt information to the user through the earphone by the volume before adjustment.
In the embodiment of the application, after the mobile terminal reduces the volume value played by the earphone, the mobile terminal can send voice prompt information to the user through the earphone by using the volume before reduction so as to prompt the user to find important information. After hearing the voice prompt, the user can respond to the found important information in time.
For example, when a user listens to music through an earphone, the collected environmental sound signal contains the name of the user, the playing volume of the earphone is reduced, the music is continuously played through the reduced volume, and a voice prompt is sent to the user through the earphone according to the volume before the reduction, so that the user is prompted that someone is calling, and the user timely gives a response after hearing the voice prompt.
In an alternative embodiment, the step 220 of analyzing the ambient sound signal to determine whether the ambient sound signal includes a predetermined speech signal may include the following steps:
analyzing the environmental sound signal, determining whether the environmental sound signal contains a voice signal sent by a preset target object, if so, executing step 230 to adjust the playing volume of the earphone so as to reduce the playing volume of the earphone; if not, the operation is ended.
The preset voice signal stored in the mobile terminal may be a voice signal sent by a certain or some preset target object, for example, a voice signal of a certain or some relatives in the home, such as a voice of a mother in the home, a call or a cry of a baby in the home, and the like. Specifically, the method may perform voiceprint recognition on the environmental sound signal to determine whether the environmental sound signal contains a voice signal of a preset target object, and the specific process may be as follows: the mobile terminal can perform noise reduction processing on the collected environmental sound signal, then extract characteristic parameter information, match the characteristic parameter information with a pre-trained voice model library, and determine that the environmental sound signal contains the voice signal of the target object when the characteristic parameter information is matched with the voice signal of one preset target object in the voice model library.
For example, when the user listens to music through the earphone, crying of a baby at home is identified in the collected environment sound signals, the playing volume of the earphone is reduced, the music is continuously played through the reduced volume, a voice prompt is sent to the user through the earphone through the reduced volume, the baby is prompted to cry and scream, and the baby is timely placated by the user after hearing the voice prompt.
In an alternative embodiment, step 210, in the earphone playing mode, a specific embodiment of collecting the ambient sound signal may include the following steps:
determining the environment type of the current environment of the mobile terminal;
when the environment type belongs to the preset environment type, the environment sound signal is collected in the earphone playing mode.
Before the ambient sound signal is collected, the type of the environment in which the mobile terminal is currently located may be determined, where the type of the environment may include, but is not limited to, home, office, library, classroom, supermarket, shopping mall, on/off the street, and the like. Specifically, the environment type of the environment where the mobile terminal is located may be determined by obtaining current location information of the mobile terminal, for example, when the mobile terminal is located at home, the environment type is home. If the mobile terminal is located on a street, the environment type is street or outdoor. The preset environment type may be an environment type that is set in advance to allow the ambient sound collection to be performed. The preset environment type can be manually set by the user according to the actual situation and/or the requirement of the user. The preset environment type may include, but is not limited to, at least one of a home, an office, a library, a classroom, a supermarket, a mall, on/off the street, and the like. When the environment type of the current environment of the mobile terminal is detected to be one of the preset environment types, the mobile terminal collects the environment sound signals in the surrounding environment when entering the earphone playing mode. When detecting that the environment type of the current environment of the mobile terminal does not belong to any one of the preset environment types, the mobile terminal may not initiate the environmental sound collection operation when entering the earphone play mode. Therefore, the environmental sound collection is triggered only in some specific environments, the energy consumption of the mobile terminal can be properly reduced, and the service life of the mobile terminal is prolonged.
It can be understood that the environment type of the current environment of the mobile terminal may be determined before the mobile terminal enters the earphone play mode, or the environment type of the current environment of the mobile terminal may be determined after the mobile terminal enters the earphone play mode, which is not limited herein.
In an alternative embodiment, the step 220 of analyzing the ambient sound signal to determine whether the ambient sound signal includes a predetermined speech signal may include the following steps:
analyzing the environmental sound signal, determining whether the environmental sound signal contains a preset voice signal matched with a preset environment type, if so, executing step 230 to adjust the earphone playing volume so as to reduce the earphone playing volume; if not, the operation is ended.
Wherein, different preset environment types can correspond to different preset voice signals. For example, when the preset environment type is home, the corresponding preset voice signal may include, but is not limited to, a name or a nickname of the user, a name of the user, a call or cry of a baby at home, and the like. For another example, when the preset environment type is an office, the corresponding preset voice signal may include, but is not limited to, a name or a nickname of the user, a name of a job title of the user (e.g., manager, zhang, etc.), and the like. The user can set different preset environment types, and can set corresponding preset voice signals for each preset environment type. Different voice signals are set under different environment types, so that the requirements can be more clear, and the management of a user is more facilitated. For example, a girlfriend in an office is likely to be irrelevant to the user, and no care is needed.
In summary, in the embodiment of the present application, the mobile terminal can acquire the environmental sound signal in the environment in real time in the earphone playing mode, and analyze the environmental sound signal to determine whether the environmental sound signal includes the preset voice signal, and if so, reduce the playing volume of the earphone, and send the voice prompt information to the user by adjusting the front volume through the earphone. Therefore, when the user uses the earphone to carry out sound reproduction operation, the embodiment of the application can also give consideration to the sound of the external environment, thereby being beneficial to avoiding the situation that the user misses important information due to wearing the earphone, and greatly improving the convenience of using the earphone by the user.
The embodiment of the application provides another adaptive earphone playing volume adjusting method. The method can be applied to a mobile terminal, and the mobile terminal is connected with an earphone. As shown in fig. 3, the method may include the steps of:
310. and collecting the environmental sound signals in the earphone play mode.
In the embodiment of the present application, the content of step 310 in the foregoing embodiment may be referred to, and is not described herein again.
320. A volume value of the ambient sound signal is obtained.
In the embodiment of the application, when the mobile terminal collects the environmental sound signal of the surrounding environment, the volume value of the environmental sound signal can be obtained. The volume value may be expressed in decibels.
330. Analyzing the environmental sound signal, determining whether the environmental sound signal contains a preset voice signal, if yes, executing step 340; if not, go to step 360.
340. And adjusting the playing volume of the earphone so as to reduce the playing volume of the earphone.
350. And sending voice prompt information to the user through the earphone by the volume before adjustment.
The specific implementation of step 330 to step 350 may refer to the content described in step 220 to step 240 in the foregoing embodiment, and is not described herein again.
360. Detecting whether the volume value of the environmental sound signal is greater than the volume value played by the earphone, if so, executing step 370; if not, the operation is ended.
370. And adjusting the playing volume of the earphone so as to increase the playing volume of the earphone.
In the embodiment of the application, when the mobile terminal determines that the environmental sound signal does not contain the preset voice signal, whether the volume value of the environmental sound signal is larger than the volume value played by the current earphone can be further detected. If the volume value of the environment sound signal is detected to be larger than the volume value played by the current earphone, it is indicated that the current external environment sound is noisy, and the hearing enjoyment of wearing the earphone by the user is likely to be influenced, so that the volume value played by the earphone can be properly improved. If the volume value of the environmental sound signal is detected to be smaller than or equal to the volume value played by the current earphone, the volume adjusting operation is finished, and the sound signal in the environment is collected continuously.
Optionally, the volume played by the headphones may be increased to a volume V ″, where V ═ V τ, V is the current volume played by the headphones (i.e., the volume played before the increase), τ is the high volume coefficient, and τ is a number greater than 1. For example, if the current playing volume of the headphone is 50 db, the high volume coefficient δ is 1.2, and the adjusted playing volume of the headphone is 60 db. If the current playing volume of the earphone is 50 db and the high volume coefficient δ is 1.3, the adjusted playing volume of the earphone is 65 db.
Optionally, the volume played by the headset may be increased to a predetermined volume value, where the predetermined volume value is a fixed value, such as 55 db, 60 db, 65 db, 70 db, or other values. It is understood that the preset volume value is within a safe volume range that the human ear can bear, and the preset volume value can be adaptively adjusted according to the actual requirement and/or application scenario of the user. For example, if the current playing volume of the earphone is 40 db and the preset volume value is 60 db, the adjusted playing volume of the earphone is 60 db. If the current playing volume of the earphone is 50 decibels and the preset volume value is 60 decibels, the adjusted playing volume of the earphone is 60 decibels.
Optionally, the volume played by the earphone may be increased to be the same as the volume value of the ambient sound signal. For example, if the current playing volume of the earphone is 50 db, and the volume value of the environmental sound signal is 60 db, the adjusted playing volume of the earphone is 60 db. If the current playing volume of the earphone is 50 db, and the volume value of the environmental sound signal is 70 db, the adjusted playing volume of the earphone is 70 db. The playing volume of the adjusted earphone cannot be higher than the maximum safe volume value which can be borne by human ears. For example, assuming that the maximum safe volume value that the human ear can bear is 80 db, if the volume value of the environmental sound signal exceeds 80 db, the volume of the earphone is adjusted to 80 db for safety.
Therefore, by implementing the method described in fig. 3, when the user uses the earphone to perform the sound reproduction operation, the user can also consider the external environment sound at the same time, thereby being beneficial to avoiding the situation that the user misses important information due to wearing the earphone, and greatly improving the convenience of using the earphone. In addition, when external environment sound is too noisy and influences the hearing enjoyment that the user wears the earphone, the volume value of earphone broadcast can be improved by adaptability, not only great improvement the user use the intelligence and the flexibility of earphone, but also promoted user's hearing impression.
