And S20, acquiring the trigger event information.

and S21, calling a detection method corresponding to the trigger event information to perform detection to obtain a detection result.
In this embodiment, the system 10 for automatically switching audio output modes calls a corresponding detection method according to the trigger event information.
In this embodiment, the electronic device 1 stores two detection methods in advance: an environmental noise detection method and an audio file tone quality detection method.
the environmental noise detection method is used for detecting the noise coefficient of the environmental noise of the electronic equipment 1 when the electronic equipment 1 is in a call state. The noise figure is a figure of merit, in dB, used to describe the amount of excessive noise present in a system. The noise figure of the ambient noise may be detected by a noise detector, such as a decibel meter or a noise detector, mounted on the electronic device 1.
The audio file tone quality detection method is used for detecting the tone quality of the played audio file when the electronic equipment 1 is in an audio playing state. The sound quality of the audio file refers to the fidelity of the transmitted and processed audio signal, the high fidelity audio compression Standard is jointly formulated by an International Standard Organization (ISO) and an International electrical union telecommunication standardization Organization (ITU-T), the sampling frequency is 48kHz, 44.1kHz, 32kHz, and the digital code rate per channel is 32 Kbps-448 Kbps. The tone quality of the audio file can be expressed by a Bit rate, the unit is kilobits Per Second (Kbps), the Bit rate refers to a sampling rate for converting digital sound from an analog format into a digital format, and the higher the sampling rate is, the better the restored tone quality is.
And S22, comparing the detection result with a preset threshold value.
In this embodiment, the system 10 for automatically switching audio output modes may preset a threshold and store the threshold in the storage unit 20. The preset threshold values include: the environmental noise coefficient threshold value and the audio file tone quality threshold value. The threshold of the environmental noise coefficient may be 50 decibels, and the threshold of the sound quality of the audio file is 160 Kbps.
In some embodiments, the preset threshold may be set by the electronic device 1 by default. In some embodiments, since the frequencies of the audio sensitive to the ears of different users are different, the preset threshold value can be set and modified by the user according to the needs or personal preferences of the user. When the user sets or modifies the threshold value, the system 10 for automatically switching the audio output mode calls the newly set or modified threshold value.
In the first embodiment, when the system 10 for automatically switching the audio output mode calls the ambient noise detection method to detect the noise coefficient of the ambient noise in which the electronic device 1 is currently located, the detected noise coefficient is compared with the ambient noise coefficient threshold. The system 10 for automatically switching the audio output mode can sample the noise signal recorded in a certain time period and then perform sound decibel detection on the sampled noise signal. Further, in order to improve the accuracy, the recorded noise signals may be subjected to a high sampling rate to obtain a plurality of noise signals, and the noise decibel values of each noise signal are summed and averaged to obtain an average noise decibel value, and the average noise decibel value is used as the noise coefficient of the environmental noise where the electronic device 1 is currently located.
In the second embodiment, when the system 10 for automatically switching audio output modes calls an audio file sound quality detection method to detect the sound quality of the audio file currently played by the electronic device 1, the detected sound quality of the audio file is compared with the audio file sound quality threshold. The system 10 for automatically switching audio output modes can sample audio signals recorded in a certain time period and then perform sound quality detection on the sampled audio signals. Further, in order to improve the accuracy, the recorded audio signals may be subjected to a high sampling rate to obtain a plurality of audio signals, and the sound quality of each audio signal is summed and averaged to obtain an average audio sound quality, and the average audio sound quality is used as the sound quality of the audio file currently played by the electronic device 1.
And S23, switching the audio output mode according to the comparison result.
In the first embodiment, when the obtained noise figure (e.g., 60 db) is greater than the environmental noise figure threshold (e.g., 50 db), which indicates that the environmental noise is greater, the system 10 for automatically switching audio output mode switches the current audio output mode to the HIFI audio output mode, and outputs the call voice of the user according to the HIFI audio output mode. When the obtained noise figure (e.g., 35 db) is less than or equal to the environmental noise figure threshold (e.g., 50 db), which indicates that the environmental noise is small, the system 10 for automatically switching audio output mode switches the current audio output mode to the normal audio output mode, and outputs the call voice of the user according to the normal audio output mode.
In the second embodiment, when the sound quality of the obtained audio file (e.g. 192Kbps) is greater than the threshold value (e.g. 160Kbps) of the sound quality of the audio file, which indicates that the sound quality of the audio file currently played by the electronic device 1 is higher, the system 10 for automatically switching the audio output mode switches the current audio output mode to the HIFI audio output mode, and plays the audio file according to the HIFI audio output mode. When the sound quality of the obtained audio file is less than (e.g., 128Kbps) or equal to the threshold value of the sound quality of the audio file (e.g., 160Kbps), which indicates that the sound quality of the audio file currently played by the electronic device 1 is high, the system 10 for automatically switching the audio output mode switches the current audio output mode to the normal audio output mode, and plays the audio file according to the normal audio output mode.
If the current audio output mode is the audio output mode that needs to be switched, the current mode may be left without performing the switching operation described above.
in summary, the method for automatically switching the audio output mode according to the present invention can invoke a corresponding detection method to perform detection according to the current mode of the electronic device 1, obtain a detection result that meets the content, compare the detection result with a preset threshold, and switch the audio output mode according to the comparison result. That is, when the electronic device 1 is in a call state, the noise coefficient of the environmental noise in which the electronic device 1 is currently located is detected, the noise coefficient is compared with a threshold of a pre-stored noise coefficient, and the HIFI audio output mode or the normal audio output mode is switched according to the comparison result. When the electronic equipment 1 is in an audio playing state, detecting the tone quality of an audio file currently played by the electronic equipment 1, comparing the tone quality of the audio file with a pre-stored threshold value of the tone quality of the audio file, and switching a HIFI audio output mode or a common audio output mode according to the comparison result. The complicated operation of manually switching the audio output mode by a user is avoided, so that the user can obtain good experience and simultaneously reduce the power consumption of the electronic equipment.
