Description

A device for detecting audio input devices and a mobile terminal

technical field

The embodiments of the present invention relate to the field of communication technologies, and in particular to a method for detecting audio input devices and a mobile terminal.

Background technique

As smart mobile terminals become more and more popular, smart mobile terminals are widely used in daily life. Among them, voice input, as one of the most basic functions of the smart mobile terminal, is very important no matter in the process of calling or in the voice message input process of the voice chat app.

Taking the mobile terminal as an example, if an external audio input device (CTIA four-segment headset/USB headset/Bluetooth headset) is plugged into the mobile terminal, the mobile terminal will preferentially select the external audio input device as the voice input device. When the external audio input device fails, the user cannot know the device failure, so the user will still use the failed external audio input device to input the input signal. This will cause the voice input signal not to meet the requirements of the user, thereby affecting the user experience.

Wherein, the audio input device includes but is not limited to a CTIA (USA Telecommunications and Internet Association) four-segment earphone, a USB (Universal Serial Bus, Universal Serial Bus) earphone, a Bluetooth earphone, and a microphone of the mobile terminal itself.

Step 102, judging whether the volume of the input signal is smaller than the minimum noise floor value corresponding to the audio input device.

In practical applications, the sound pressure value of the ambient noise floor in a specific type of input device is constant. For each input device, a minimum noise floor value corresponding to the type of the device will be provided according to the type of the device. Therefore, it can be judged based on the comparison result of the volume of the input signal and the minimum noise floor value corresponding to the audio input device. In particular, the minimum noise floor value here is the minimum noise floor value corresponding to the type of the audio input device.
