The embodiment of the invention provides a sound output control method and a mobile terminal, wherein after detecting that an earphone is connected to the mobile terminal, sound is not directly switched from loudspeaker playing to earphone playing, but whether a sound output channel is switched is determined by combining collected image data, so that a user can be ensured to continuously receive and hear audio in the process of wearing the earphone by the user, the problem that the user receives the audio data and is interrupted because the user does not wear the earphone well is avoided, and the listening experience of the audio data of the user is improved.
In an embodiment of the present invention, a mobile terminal may be a smart phone, a tablet computer, and the like, taking the smart phone as an example, fig. 1 is a first flowchart of a sound output control method provided in an embodiment of the present invention, where the method in fig. 1 can be executed by the mobile terminal, and is particularly executed by a program module disposed in the mobile terminal, as shown in fig. 1, the method at least includes the following steps:
the method includes the steps of S101, after the fact that an earphone is connected to a mobile terminal is detected, controlling a front camera of the mobile terminal to acquire image data, specifically, when the mobile terminal plays a multimedia file with sound through a loudspeaker, for a wired earphone, when it is detected that an earphone plug is inserted into an earphone interface of the mobile terminal, determining that the earphone is connected to the mobile terminal, for a wireless earphone, when it is detected that the earphone and the mobile terminal are successfully paired, determining that the earphone is connected to the mobile terminal, after it is determined that the earphone is connected to the mobile terminal, firstly, controlling the front camera of the mobile terminal to be started, and shooting images to acquire needed image data.
S102, determining whether a switching condition of a sound output path is satisfied according to the acquired image data, specifically, after acquiring current image data by using a front-facing camera of the mobile terminal, performing identification analysis on the image data, and determining whether to perform sound output path switching based on an identification result, that is, if it is identified that a user using the mobile terminal has worn an earphone, it indicates that the user can receive audio data through the earphone, and at this time, playing sound by a speaker is switched to outputting sound by the earphone.
If not, executing S103, keeping the first audio channel corresponding to the sound output by the speaker to be conducted, specifically, if it is not identified that the user using the mobile terminal wears the earphone, at this time, there may be a situation that the user cannot receive the audio data through the earphone, so that the sound is continuously played through the speaker, so that the user can normally receive the currently played audio data, and meanwhile, continuing to execute the step S101 according to the preset time interval, so as to obtain the next image data for identification and analysis, and control the sound output of the mobile terminal according to the identification and analysis result.
If yes, executing S104, disconnecting the first audio channel corresponding to the speaker output sound, and conducting the second audio channel corresponding to the earphone output sound, specifically, if it is recognized that the user using the mobile terminal has worn the earphone, switching the first audio channel corresponding to the speaker of the mobile terminal as the sound output channel to the second audio channel corresponding to the earphone access end of the mobile terminal for conducting.
In the embodiment of the invention, after the earphone is detected to be connected to the mobile terminal, a front-facing camera of the mobile terminal is controlled to acquire image data; judging whether a sound output channel switching condition is satisfied or not according to the image data; if not, keeping a first audio channel corresponding to the output sound of the loudspeaker to be conducted; if yes, the first audio channel corresponding to the sound output by the loudspeaker is disconnected, and the second audio channel corresponding to the sound output by the earphone is connected. After the earphone is detected to be connected with the mobile terminal, the sound is not directly switched from the loudspeaker to the earphone to be played, but the switching of a sound output channel is determined by combining the collected image data, namely, whether the loudspeaker is stopped playing the audio data is determined, so that the user can be ensured to continuously listen to the audio in the process that the user wears the earphone, the problem that the user receives the audio data and is interrupted because the user does not wear the earphone well is avoided, and the listening experience of the audio data of the user is improved.
In the embodiment of the present invention, whether a switching condition of a sound output path is satisfied is determined by identifying whether a face image wearing an earphone exists in the acquired image data, specifically, as shown in fig. 2, the step S102 of determining whether the switching condition of the sound output path is satisfied according to the acquired image data specifically includes:
s1021, performing face recognition on the acquired image data, and judging whether a preset face image exists in the image data, specifically, extracting contour information in the image data by adopting an image recognition algorithm, and judging whether the preset face image exists based on the extracted contour information;
if the preset face image exists, S1022 is executed to determine whether the face on the preset face image is wearing an earphone, specifically, after the preset face image exists in the image data, whether the earphone is worn or not is identified, an image segmentation algorithm is adopted to extract an ear region image from the face image, whether the earphone image exists in the extracted ear region image or not is judged, wherein, at least one preset face image can be stored in the mobile terminal in advance, so that if the condition that other users wear the earphones of other mobile terminals is collected, the condition of error switching can not occur, that is, when other face images than the preset face image exist in the image data and the other face images wear the earphones of other mobile terminals, at this time, the preset face image in the image data cannot be determined, so that the switching of the sound output channel cannot be carried out;
if the user determines that the user does not wear the earphone, determining that the switching condition of the sound output path is not met, namely executing step S103, specifically, if it is determined that the user does not wear the earphone, it indicates that the user may not wear the earphone well, and if the user directly turns off the sound played by the speaker, the sound played by the earphone is changed to the sound played by the earphone, so that the user may not receive the currently played audio data before the user finishes wearing the earphone;
if the user determines that the user wears the earphone, the user determines that the switching condition of the sound output path is met, that is, step S104 is executed, specifically, if the user determines that the user wears the earphone, the user can receive the audio data through the earphone, and at this time, the speaker playing sound is turned off, and the user changes to the earphone playing sound.
Further, considering that it cannot be determined whether the user wears the earphone at present for the case where the face image is not detected, the method may be implemented in a manner of displaying a prompt message, and the user may decide whether to switch the sound output path, based on which, in fig. 2, after performing face recognition on the acquired image data and determining whether the preset face image exists in the image data, the method further includes:
if the preset face image does not exist, S1023 is executed to display prompt information for switching the audio channel and execute corresponding control operation according to the selection operation instruction, specifically, as shown in fig. 3, after it is determined that the preset face image does not exist in the image data, a prompt box may be displayed on the display interface of the mobile terminal, and corresponding prompt information "detect that the earphone is connected, ask for whether to switch the sound to the earphone for output? "and displaying two options of" cancel "and" switch ", if it is detected that the user selects the" cancel "option, determining that the switching condition of the sound output channel is not satisfied, i.e. continuously keeping the first audio channel corresponding to the output sound of the speaker on; correspondingly, if the user is detected to select the 'switching' option, the switching condition of the sound output channel is determined to be met, namely, the first audio channel corresponding to the sound output by the loudspeaker is disconnected, and the second audio channel corresponding to the sound output by the earphone is connected.
Further, considering that, for the case that the image data includes a face image but it is recognized that the user does not wear an earphone, it may be that the other user except the face image included in the image data wears an earphone connected to the mobile terminal, that is, the first target user corresponding to the face image included in the image data does not wear an earphone, but the second target user not included in the image data wears an earphone, at this time, the second target user needs to receive the audio data through the earphone, therefore, in order to ensure that the second target user can normally receive the audio data through the earphone, a timeout condition is preset, in the case that the timeout condition is not satisfied, the next image data is continuously obtained according to a preset time interval for identification and analysis, and the sound output of the mobile terminal is controlled according to the identification and analysis result, and once the timeout condition is satisfied, by displaying the prompt information, the method for switching the audio output path according to the user' S discretion, specifically, as shown in fig. 4, after keeping the first audio path corresponding to the audio output from the speaker conducting at S103, further includes:
s105, judging whether the image data acquisition operation meets a preset overtime condition or not; specifically, even after it is determined that the face image in the image data does not wear the earphone and the speaker plays the sound, the operation of acquiring the next image data through the front-facing camera is not continuously executed, but whether a preset timeout condition is met is judged first, if it is determined that the timeout condition is met, the acquisition of the image data is stopped, and whether the switching of the sound output path is performed is determined by the user, so that the second target user can be ensured to normally receive the audio data through the earphone in the case that the second target user wears the earphone except the acquired image data.
If the preset overtime condition is met, executing S1023, displaying prompt information for whether to switch the audio channel and executing corresponding control operation according to the selection operation instruction; specifically, as shown in fig. 4, a prompt box is also displayed on the display interface of the mobile terminal, and a corresponding prompt message "detect that the earphone is connected, ask for whether to switch the sound to the earphone output? "and displaying two options of" cancel "and" switch ", if it is detected that the user selects the" cancel "option, determining that the switching condition of the sound output channel is not satisfied, i.e. continuously keeping the first audio channel corresponding to the output sound of the speaker on; correspondingly, if the user is detected to select the 'switching' option, the switching condition of the sound output channel is determined to be met, namely, the first audio channel corresponding to the sound output by the loudspeaker is disconnected, and the second audio channel corresponding to the sound output by the earphone is connected.
If the preset timeout condition is not met, executing S101, and controlling a front-facing camera of the mobile terminal to acquire image data, specifically, during a process that a first target user corresponding to a face image included in the image data is wearing an earphone, so as to acquire next image data according to a preset time interval, and determining whether the face image included in the image data is wearing an earphone.
As shown in fig. 5, the step S105 of determining whether the image data acquiring operation meets the preset timeout condition specifically includes:
s1051, judging whether the earphone access time is larger than a target time threshold value, wherein the target time threshold value is determined based on the average value of the historical earphone wearing time of the user; specifically, since image data acquisition is started after detecting that the earphone is connected to the mobile terminal, the earphone connection time is detection time for identifying whether the user wears the earphone or not, a timer in the mobile terminal is started to start timing after detecting that the earphone is connected to the mobile terminal, the target time threshold may be preset or determined by combining an average value of historical earphone wearing time of the user, and a mode of determining the target time threshold by combining historical earphone wearing time of the user is adopted, so that accuracy of judging whether a timeout condition is met can be improved, compared with a target time threshold corresponding to a user with shorter historical earphone wearing time, a target time threshold corresponding to a user with longer historical earphone wearing time is larger, and in addition, in order to prevent detection omission, on the basis of the average value of the historical earphone wearing time of the user, the target time threshold is set larger.
If the time is greater than the target time threshold, it is determined that the preset timeout condition is met, that is, step S1023 is executed, specifically, if the earphone access time is greater than the target time threshold, there may be a case where the accessed mobile terminal earphone is worn by another user except for the face image included in the image data, and at this time, the user may decide by himself whether to switch the sound output path by displaying the prompt information.
If the time is not greater than the target time threshold, determining that the preset timeout condition is not met, namely executing step S101, specifically, if the earphone access time is not greater than the target time threshold, obtaining next image data according to a preset time interval, and determining whether a face image contained in the image data is worn with an earphone.
For example, for a certain target user, obtaining the historical wearing time of the target user, if the average value of the historical wearing time of the target user is 3s, setting the target time threshold to 3s, and further if the earphone access time is greater than 3s, there may be a case where the accessed mobile terminal earphone is worn by other users except for the face image included in the image data, and thus it is determined that the preset timeout condition is satisfied; if the earphone access time is not more than 3s, at this time, the next image data needs to be acquired according to the preset time interval, and therefore, the preset timeout condition is determined not to be met.
According to the sound output control method in the embodiment of the invention, after the earphone is detected to be connected to the mobile terminal, the front-facing camera of the mobile terminal is controlled to acquire image data; judging whether a sound output channel switching condition is satisfied or not according to the image data; if not, keeping a first audio channel corresponding to the output sound of the loudspeaker to be conducted; if yes, the first audio channel corresponding to the sound output by the loudspeaker is disconnected, and the second audio channel corresponding to the sound output by the earphone is connected. After the earphone is detected to be connected with the mobile terminal, the sound is not directly switched from the loudspeaker to the earphone to be played, but whether the sound output channel is switched is determined by combining the collected image data, so that the user can be ensured to continuously receive and hear the audio in the process that the user wears the earphone, the problem that the user receives the audio data and is interrupted because the user does not wear the earphone is solved, and the user audio data listening experience is improved.
