Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and without
It is of the invention in limiting.
Mobile terminal in the embodiment of the present invention includes but is not limited to mobile phone and panel computer etc., with voice call, record
Other mobile terminals of the functions such as sound, audio broadcasting are also within the protection domain of the application.
With reference to shown in Fig. 1, the mobile terminal in the embodiment of the present invention includes circuit board (not shown), housing 10 and closely set
At least two pieces piezoelectric ceramic pieces of the insulation set two-by-two of the inner surface of housing 10 are placed in, and piezoelectric ceramic piece is electrically connected in electricity
Road plate, circuit board is provided with drive circuit, drive circuit driving piezoelectric ceramic piece, to realize microphone, the receiver of mobile terminal
Or the function such as loudspeaker.
Specifically, it is using the realization principle of piezoelectric ceramics, due to the function that mechanical energy and electric energy are mutually changed can be realized
Material, piezoelectric ceramics has piezo-electric effect and inverse piezoelectric effect.So-called piezo-electric effect, i.e., when piezoelectric ceramics is by external influence
Power, can produce electric charge in dielectric surface；This process, converts mechanical energy into electric energy.So-called inverse piezoelectric effect, refers to work as
Piezoelectric ceramics surface adds voltage, can be allowed to produce deformation；This process, then realize electric energy and changed to mechanical energy.Work as sound wave
Energy acts on piezoelectric ceramic piece, produces piezo-electric effect, and piezoelectric ceramic piece dielectric surface can be strong and weak according to voice signal, and frequency is high
Low yield gives birth to charge signal so that voice signal is converted to electric signal and is recorded, and realizes microphone pickup function.When in pressure
Electroceramics piece, loads audio electrical signal, under inverse piezoelectric effect effect, and piezoelectric ceramics sector-meeting produces phase according to audio electrical signal
The vibration change answered so that electric signal is converted to voice signal, realizes that loudspeaker, receiver play the function of sound.Connect in addition, working as
When answering a call, voice signal is transferred in ear by way of osteoacusis.
Further, piezoelectric ceramic piece includes the first piezoelectric ceramic piece 20, the second piezoelectric ceramic piece 30 and the 3rd piezoelectricity pottery
