MOVEABLE COVER FOR THE SPEAKER-OPENING OF A MOBILE DEVICE

The present disclosure provides an audio output mode adjustment structure, method, apparatus and electronic device (1). The audio output mode adjustment structure comprises a sound output channel (2) communicating an interior and an exterior of the electronic device (1) and an adjustment unit (3) (3). An opening of the sound output channel (2) is located at the top of the electronic device (1). The adjustment unit (3) moves relative to the opening of the sound output channel (2) so that when the electronic device (1) outputs audio in a loud-speaking mode, the adjustment unit (3) does not cover the sound output channel (2), and sound waves propagate in a straight line through the opening of the sound output channel (2), and when the electronic device (1) outputs audio in the handset mode, the adjustment unit (3) covers the opening of the sound output channel (2), so that the sound waves propagate toward a display screen side of the electronic device (1) through the opening of the sound output channel (2). The propagation direction of the sound waves at the opening of the sound output channel (2) can be changed by the adjustment unit (3), and the audio output mode of the electronic device (1) can be adjusted to the handset mode or the loud-speaking mode. While keeping normal call function of the electronic device (1), the stereo effect of the audio in the loud-speaking mode is improved to meet the user's demand for the sound quality of the loud-speaking.
