Description

A kind of audio control method, circuit, graphic user interface, electronic equipment and storage medium Technical field

The present invention relates to electronic field more particularly to a kind of audio control method, circuit, graphic user interface, electronic equipment and storage mediums.

Background technique

With the development of communication technologies, mobile phone is widely used and popularizes, and mobile phone just like has become the necessity of people's life.More and more functions are integrated into above mobile phone, such as MPS function, camera function, video capability, game function.But in reality, user is extremely complex using the environment of mobile phone, for example, on bus, in business district, factory it is medium, these environment be it is more noisy, when in these environment, the sound of mobile phone speaker output is just largely submerged.Therefore, user is usually that extraneous interference is excluded using earphone.

There are many type, such as three-section earphone, first kind four-section type headsets and the second class four-section type headset etc. for earphone on the market at present.

Fig. 1 a is three-section earphone structure chart, and as shown in Figure 1a, three-section earphone is divided into three sections, and first is followed successively by L channel, right channel, ground to third section.

Fig. 1 b is first kind four-section type headset structure chart, and as shown in Figure 1 b, first kind four-section type headset is divided into four sections, and first to the 4th section is followed successively by L channel, right channel, ground, microphone.

Fig. 1 c is the second class four-section type headset structure chart, and as illustrated in figure 1 c, the second class four-section type headset is divided into four sections, and first to the 4th section is followed successively by L channel, right channel, microphone, ground.

Correspondingly, there is pin corresponding with earphone in earphone interface:

Fig. 2 a is three-section earphone interface diagram, and as shown in Figure 2 a, three-section earphone interface includes L channel, right channel, three, ground pin.

Fig. 2 b is first kind four-section type headset interface diagram, and as shown in Figure 2 b, first kind four-section type headset interface includes for L channel, right channel, ground, four pins of microphone.

Fig. 2 c is the second class four-section type headset interface diagram, and as shown in Figure 2 c, the second class four-section type headset interface includes for L channel, right channel, microphone, four, ground pin.

When earphone is inserted into earphone interface, each section of earphone accordingly contacts with each pin of earphone interface.

Fig. 3 is the schematic diagram of first kind four-section type headset insertion first kind four-section type headset interface, as shown in figure 3, illustrating the case where earphone and earphone interface come into full contact with so that first kind four-section type headset is inserted into first kind four-section type headset interface as an example.
