Fig. 1 is the structure diagram of the mobile terminal 10 according to an exemplary embodiment.In the embodiments of the present disclosure, Mobile terminal 10 can be that mobile phone, tablet device, wearable device, digital broadcast terminal, messaging devices, individual digital help The electronic equipments such as reason.
As shown in Figure 1, mobile terminal 10 includes:Housing 11, structural support 12, processor 13,14 and of power amplifier Vibrator 15.
Housing 11 includes following three parts:Front panel, rear panel and center, above three part are enclosed closing sky Between be known as housing 11.In the embodiments of the present disclosure, the shape of housing 11 is not construed as limiting, for example, housing 11 can be in cuboid Shape, and there are certain radian for the corner of housing 11.
Structural support 12 is located inside housing 11.Structural support 12 plays the structure of mobile terminal 10 support and makees With.Structural support 12 usually selects the material with higher hardness and intensity to be made, to ensure that it is curved that mobile terminal 10 is not easy Folding, damage.Structural support 12 can select the materials such as aluminium alloy, kirsite, stainless steel or liquid metal, in practical application In, demand that can be according to reality to the hardness and strength of structural support 12, selects suitable material.Structural support 12 can be with Using in-mould injection technological forming.
Processor 13 is the arithmetic core and control core of mobile terminal 10.Alternatively, processor 13 is AP (Application Processor, application processor), AP are used for the operating system and application program for running mobile terminal 10.
The input terminal of power amplifier 14 is coupled with processor 13, output terminal and 15 coupling of vibrator of power amplifier 14 Close.Power amplifier 14 is used to receive the signal from processor 13, and carries out power amplification to the signal.
Vibrator 15 is attached on structural support 12, such as vibrator 15 invests structural support 12 using double faced adhesive tape On.Vibrator 15 can produce vibration under the control of processor 13.Alternatively, vibrator 15 for Horizontal vibrator or Vertical linearity vibrator, Horizontal vibrator refer to vibrator of the direction of vibration along the width of mobile terminal 10, vertically Linear vibrator refers to vibrator of the direction of vibration along the thickness direction of mobile terminal 10.The volume of Horizontal vibrator is opposite It is larger, usually it is in the rectangular shape of flat;The volume of vertical linearity vibrator is relatively small, is usually in the cylinder of flat Shape.
In the embodiments of the present disclosure, processor 13 is used to audio signal being sent to power amplifier 14;Power amplifier 14 are used to receive the audio signal from processor 13, which is amplified and drives vibrator 15 to vibrate; Vibrator 15 is used under the driving of power amplifier 14, is made a sound by vibration.
Audio signal is the frequency of the regular sound wave with voice, music and audio, changes in amplitude information carrier. In practical application scene, the audio signal that processor 13 is sent to power amplifier 14 includes but is not limited to as follows:Such as phone, The voice signal of opposite end in the scenes such as voice communication, video calling, wait opposite end answer during the tinkle of bells, the audio such as music letter Number, speech message in the application such as instant messaging application, social networking application, etc..Alternatively, processor 13 and power amplifier 14 Input terminal between be connected by I2S buses, I2S buses be exclusively used in transmission audio signal bus.Processor 13 passes through I2S Audio signal is sent to power amplifier 14 by bus.Power amplifier 14 receive the audio signal from processor 13 it Afterwards, power amplification is carried out to the audio signal and obtains amplified signal, and amplified signal is exported to vibrator 15 to drive vibration Device 15 produces vibration, and vibrator 15 is by vibrating the sound that the sound sent is the above-mentioned audio signal that processor 13 is sent.
Alternatively, power amplifier 14 selects that transient response is good, high-tension power amplifier, as the transistor of high pressure is put Big device, to improve the performance of vibrator 15.Exemplarily, power amplifier 14 can select grace intelligence Pu semiconductor (NXP) company The power amplifier chips of 9891 either 9894 models can also select 2557 or 2560 types of Texas Instrument (TI) company Number power amplifier chip.
Alternatively, when vibrator 15 is using vertical linearity vibrator, as shown in Fig. 2, the sound warp that vibrator 15 is sent The touch display screen 16 for crossing the front panel positioned at housing 11 is outwards propagated.When front panel of user's human ear close to housing 11, just It can hear the above sound.
Alternatively, as shown in Figure 1, the top center and side center of vibrator 15 close to housing 11 are set.On the one hand, will Vibrator 15 is set close to center, preferably can outwards be propagated sound, is received beneficial to human ear;On the other hand, due to called Device is generally arranged at the top of mobile terminal, therefore vibrator 15 is arranged on the upper of mobile terminal 10 in the embodiments of the present disclosure Half part, meets the history use habit of user.
Alternatively, mobile terminal 10 further includes:Touch display screen and PCB (not shown in figure 1)s.Processor 13 and power are put Big device 14 is arranged on PCB.PCB is used for the electronic component for carrying mobile terminal 10, such as processor 13, power amplifier 14 Deng can realize the electrical interconnection between above-mentioned electronic component.First face of structural support 12 is opposite with touch display screen, knot Second face of structure supporting item 12 is opposite with PCB.Vibrator 15 is attached on the second face of structural support 12, in order to and PCB On power amplifier 14 connect.
It should be noted that mobile terminal 10 is commonly provided with the vibration for being useful for producing vibration prompt or touch feedback Device.It is used for the vibrator 15 that makes a sound in the embodiment of the present disclosure with above-mentioned for producing shaking for vibration prompt or touch feedback Dynamic device can be two mutual independent vibrators or the same vibrator of multiplexing.Alternatively, when the same vibration of multiplexing During device, processor 13 is additionally operable to send first control signal to power amplifier 14;Power amplifier 14 is additionally operable to according to first Control signal driving vibrator 15 is vibrated to produce vibration prompt or touch feedback.When vibrator 15 is carried for producing vibration Show or during touch feedback, vibrator 15 is vibrated under the first vibrational state;When vibrator 15 is used to send audio signal Sound when, vibrator 15 is vibrated under the second vibrational state.Wherein, the first vibrational state include the first vibration frequency and First amplitude, the second vibrational state include the second vibration frequency and the second amplitude, and the first vibration frequency is less than the second vibration frequency, And first amplitude be more than the second amplitude.Exemplarily, the first vibration frequency is in 110Hz or so, the second vibration frequency in 200Hz extremely 8kHz or so.Alternatively, processor 13 is additionally operable to by I2C (Inter-Integrated Circuit) buses to power amplification Device 14 sends first control signal.
With reference to reference to figure 3A and Fig. 3 B, it illustrates the circuit signal between power amplifier 14 and vibrator 15 Figure.U711 chips shown in figure are a power amplifier 14, the output terminal SPKR_P1 and SPKR_N1 of U711 chips in Fig. 3 B Two input terminals of vibrator 15 are connected respectively.Audio signal is inputted to U711 chips by I2S buses, and U711 chips are to audio Signal carries out power amplification and obtains amplified signal, and amplified signal is exported to vibrator 15 to drive vibrator 15 to produce vibration Make a sound.
The mobile terminal 10 that the embodiment of the present disclosure provides, the function of receiver is substituted by vibrator 15, without The perforate on the front panel of mobile terminal 10, contributes to the screen accounting of further lifting mobile terminal 10.
In addition, vibrator 15 can be used for realization vibration prompt, haptic feedback functions with what is be equipped with mobile terminal 10 Vibrator is multiplexed, and saves the cost of receiver, and save the inner space of mobile terminal 10.
