Problems solved by technology

These two solutions have disadvantages. The volume adjustment operation of the former is relatively cumbersome and inconvenient, and is usually used for fixed volume settings; the latter increases the structural space and requires external buttons. The product is thick and unsightly, and it also increases the water resistance of the mobile terminal. difficulty

Abstract

The invention provides a volume adjusting device and method and a mobile terminal. The volume adjusting device comprises a control display module, an intelligent power amplifier and a loudspeaker unit. One end of the intelligent power amplifier is electrically connected with the control display module, and the other end of the intelligent power amplifier is electrically connected with the loudspeaker unit; the intelligent power amplifier performs power amplification on the audio signal from the control display module and outputs the amplified audio signal to the loudspeaker unit, detects the working current of the loudspeaker unit, and output a first feedback signal to the control display module when the working current changes in a preset manner; and the control display module controls adisplay screen to display a volume adjustment interface according to the first feedback signal, and adjusts the volume of the mobile terminal according to a volume adjustment instruction from the volume adjustment interface. The volume adjustment mode provided by the invention is simple to operate, and the structural space is not increased, so that the product is lighter, thinner, more attractiveand more intelligent.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a volume adjustment device and method, and a mobile terminal. Background technique [0002] At present, smart terminal devices, including smart wearable devices, mainly have two methods of volume adjustment, one is to adjust the volume in the system settings, and the other is to add volume adjustment buttons. These two solutions have disadvantages. The volume adjustment operation of the former is relatively cumbersome and inconvenient, and is usually used for fixed volume settings; the latter increases the structural space and requires external buttons. The product is thick and unsightly, and it also increases the water resistance of the mobile terminal. difficulty. Contents of the invention [0003] One of the objectives of the present invention is to provide a volume adjustment device and method, and a mobile terminal in order to overcome the deficiencies in the pr...
