Audio commentary

Hello, everyone. The meeting will answer your questions. Oppo phone does not have sound display headphone mode, oppo phone has no sound what is going on ah many people do not know, now let's take a look at it!

Answer:

1. If the headset is not plugged into the phone, the headset icon will still be displayed, which will cause the phone to mute and play. Make sure that the speakers are not clogged and that the sound outlets of the speakers are not clogged, such as protective housings and sleeves. Try to clean the dust screen of the speakers. You can use a soft long brush dipped in alcohol, brush off the dustproof net in the sound hole and observe whether the sound returns to normal.

2. Mobile phone frequency range:

3. 10hz-15000Hz, the speaker must be set in the sound options set by the phone, or you can press the volume plus or minus button directly when making a phone call or listening to music. When audio signals with the same voltage and different frequencies are applied to the loudspeaker, the sound pressure generated by the loudspeaker will change. Generally speaking, the sound pressure is higher in medium audio and lower in low and high audio. When the sound pressure drops to a certain value of medium audio, the high and low frequency range is called a loudspeaker with good frequency response characteristics as far as possible. If the phone is tilted, the distance between the sound coming from the left and right speakers into the ear will become longer. Try not to use devices that will cause resonance around the loudspeaker assembly, separate the left and right speakers as far as possible, and minimize the difference in characteristics between the left and right speakers.

This is the end of this article. I hope it will be helpful to all of you.
