What does it mean to have a horn symbol on your mobile phone?

The horn symbol on your mobile phone should be the ringtone option of your mobile phone. Generally, there is a 3-4 mode display. First, it's just a horn, which should be a normal bell mode. There are water ripples on the left and right sides of the horn, which should be vibration mode. There is also a diagonal line in the middle of the speaker, which should be silent mode! ! ! !
