[0078] image 3 The basic flow chart of the volume adjustment method provided in this embodiment, this method can be applied to any type of terminal with audio playback function, not limited to mobile terminals, but can also be applied to fixed terminals such as digital TVs, desktop computers, and car navigation equipment . The volume adjustment method includes:
[0079] S301. When the audio output unit of the terminal continuously outputs audio signals, determine whether there is an external object approaching or moving away from the terminal.
[0080] Specifically, the external object may be a part of the user's body such as a palm, or may refer to an inanimate object such as a book. Because the acoustic signal propagates in all directions, there is no specific limitation on the direction of movement of the external object approaching or moving away from the terminal, and the approaching or moving away of the external object in any direction above the terminal plane can be...

[0103] Figure 5 It is a detailed flow chart of the volume adjustment method provided in the second embodiment of the present invention. The volume adjustment method includes:
[0104] S501. When the audio output unit of the terminal continuously outputs audio signals, the audio receiving unit receives N reflected audio signals corresponding to the transmitted audio signals within a first preset time range.
[0105] S502, according to the acquisition time of the transmitted audio signal, the receiving time of the reflected audio signal and the transmission speed of the audio signal, judge whether the transmission distance of the received reflected audio signal changes, if so, then go to S503, if not, then return to S501 .
[0106] Where N takes an integer value greater than or equal to 2. The following takes n sampling points as an example to give an example of the specific judgment process of whether there is an external object approaching or far away from the terminal. For ...
