Abstract

The invention is applicable to the technical field of electronics and provides a method and a device for switching built-in and external loud speakers. The method comprises the steps of a, detecting whether the external loud speaker is connected or not, and if so, turning to a step b; and b, controlling a sound power amplifier unit to switch sound output channels and outputting the sound via the sound output channel of the external loud speaker. According to the technical scheme provided by the invention, the control mode is simple and has high reliability; and the switching of the sound output between the built-in and external loud speakers can be realized automatically without switching operation of a user.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a method and a device for switching between internal and external loudspeakers. Background technique [0002] With the development of flat panel display technology, the application of flat panel displays is becoming more and more common. In addition to better display effects, flat-panel displays have another advantage: while display screens continue to expand in size, their body thicknesses are getting thinner and thinner. [0003] Although the flat-panel display body is thin and has the advantages of being beautiful and taking up less space, due to the limitation of the internal structure of the product, the size and placement of the flat-panel display speakers are limited, and the speaker cavity cannot be formed, so the effect of its output sound will be affected to some extent. [0004] In order to overcome the above defects, users who have higher requirement...
