Embodiment Construction

[0025] see figure 1 , figure 1 It is a schematic structural diagram of an electronic device provided in an embodiment of the present application. The electronic device 20 may be a smart phone, a tablet computer, a PDA (Personal Digital Assistant) and the like.

[0026] Wherein, the electronic device 20 may include at least five piezoelectric ceramic units, such as the piezoelectric ceramic unit 200 , and the piezoelectric ceramic unit 200 is made of ceramic material. The piezoelectric ceramic unit 200 can convert mechanical energy and electrical energy to each other. When the piezoelectric ceramic unit 200 converts electrical energy into mechanical energy, the piezoelectric ceramic unit 200 can output a sound signal. At this time, the piezoelectric ceramic unit 200 can be used as an electronic Earpiece or speaker of the device 20; when the piezoelectric ceramic unit converts mechanical energy into electrical energy, the piezoelectric ceramic unit 200 can collect sound signal...

Abstract

Provided in embodiments of the present invention are an electronic apparatus and a sound emission control method thereof. The sound emission control method is applied in an electronic apparatus comprising a display screen, at least five piezoelectric ceramic units and a processor. The processor is respectively electrically connected to the display screen and the piezoelectric ceramic units. The processor can determine a sound emission state of a piezoelectric ceramic unit according to a distance between a location of a preset object image displayed on the display screen and the piezoelectric ceramic unit, thereby enhancing audio playback performance of the electronic apparatus.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to an electronic device and a sound control method thereof. Background technique [0002] With the development of communication technology, electronic devices such as smartphones are becoming more and more popular. Electronic equipment is usually provided with a speaker, and the speaker can output an audio signal corresponding to the picture on the display screen, but the audio signal can only be output at a position corresponding to the speaker, and the sound playback effect is poor. Contents of the invention [0003] Embodiments of the present application provide an electronic device and a sound emission control method thereof, which can improve the sound playback effect of the electronic device. [0004] An embodiment of the present application provides an electronic device, including: [0005] a display screen for displaying images; [0006] At least five piez...
