Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.
Example one
Fig. 3 is a flowchart of a first embodiment of an output volume control method according to the present invention. An output volume control method, the method comprising:
s1, detecting whether the external audio acquired by the equipment contains a preset detection signal in real time in the audio output process of the equipment;
s2, if the external audio is detected to contain the detection signal, turning down the output volume of the audio according to a preset first volume regulation relation;
s3, after the volume of the audio output is reduced according to the first volume regulation relation, continuously detecting whether the external audio contains the detection signal;
and S4, if the external audio is detected to no longer contain the detection signal, turning up the output volume of the audio according to a preset second volume regulation relation.
Optionally, in this embodiment, the device may be a mobile terminal device such as a mobile phone, and further, when the device is in audio output, it may be understood that an external device such as an earphone and a headset connected to the mobile terminal device outputs audio, and at this time, because the user is in a closed audio output environment, suggestive sound of an external environment may be missed, so this embodiment will specifically solve this problem;
optionally, in this embodiment, when a mobile terminal device such as a mobile phone is in an earphone to answer a call or the earphone listens to voice information, since the ear of the user is close to the earphone of the device, especially when the user is in an environment similar to a closed audio output environment when the user is in a tight fit, suggestive sound of the external environment may also be missed, so this embodiment will also specifically solve this problem;
optionally, in this embodiment, in the process of outputting the audio by the device, it is detected in real time whether the external audio acquired by the device includes a preset detection signal, where the preset detection signal is voice information that needs to be acquired and is preset by a user, for example, broadcast information of a train station, broadcast information of an airport, arrival information of a bus, and the like;
optionally, in this embodiment, if it is detected that the external audio includes the detection signal, the output volume of the audio is reduced according to a preset first volume regulation relationship, it should be noted that, in this embodiment, when the detection signals corresponding to the broadcast information of the train station, the broadcast information of the airport, the arrival information of the bus and the like are identified, the output volume of the audio starts to be reduced and is in a continuously reduced state, and at this time, the user may more clearly obtain the broadcast information of the train station, the broadcast information of the airport, the arrival information of the bus and the like in the external environment;
optionally, in this embodiment, after the volume of the audio output is reduced according to the first volume regulation relationship, it is continuously detected whether the external audio includes the detection signal, where the purpose of the continuous detection is to enable a user to continuously listen to subsequent specific information contents, such as broadcast information of a train station, broadcast information of an airport, arrival information of a bus, and the like, in an external environment, and therefore, a smaller output volume needs to be maintained for a period of time;
optionally, in this embodiment, after the volume of the audio output is reduced according to the first volume regulation relationship, it is continuously detected whether the external audio includes the detection signal; if the external audio is detected to no longer contain the detection signal, the output volume of the audio is increased according to a preset second volume regulation and control relationship, and it can be understood that when a user knows the subsequent specific information contents of the broadcasting information of the railway station, the broadcasting information of the airport, the arrival information of the bus and the like in the external environment, that is, when the subsequent specific information contents of the broadcasting information of the railway station, the broadcasting information of the airport, the arrival information of the bus and the like in the external environment are broadcasted, the user does not need to listen to the external sound again, and at the moment, the original output volume of the user can be recovered;
optionally, in this embodiment, for setting and determining the detection signal, the terminal outputs sound by using a reverse sound wave and a window function, which can actively detect a specific signal outside the device, so as to actively turn down the sound output volume of the device, so as to ensure that the user does not influence the acquisition of important information due to the sound production of the device when using the device;
