With the iteration and the update of the technology, a series of new-form electronic devices emerge from the market successively, and screen sounding electronic devices are produced according to the demand of no hole. In the related art, most screen sound-producing electronic devices adopt the deformation generated by the inverse piezoelectric effect of piezoelectric ceramics to drive the screen to deform, so as to push air to produce sound and realize the functions of a receiver and a loudspeaker. The screen is driven to sound by deformation generated by the inverse piezoelectric effect of the piezoelectric ceramic, multiple layers of piezoelectric materials are generally required to be stacked, the requirement on the process is high, and meanwhile, higher peak voltage is required to drive, so that the overall cost is high; in addition, according to the frequency domain impedance characteristic of the piezoelectric ceramic, the low frequency thereof is far inferior to that of the conventional moving coil horn even under a very high voltage drive. There are also manufacturers that use moving coil exciters to propel screens to sound to perform earpiece and speaker functions. The screen sound production is realized by adopting the scheme of the moving coil exciter, although the driving voltage and the cost are lower, the impedance of the moving coil exciter is sharply increased after high frequency, so that the high frequency performance of the moving coil exciter is greatly attenuated, and the loudness and the tone quality are poor.
Referring to fig. 1, an electronic device 100 according to an embodiment of the present disclosure includes a screen 10, a piezoelectric ceramic 22, and a moving coil actuator 32. The piezoelectric ceramic 22 is attached to the screen 10 and the moving coil actuator 32 is attached to the screen 10. When the electronic device 100 is in the play mode, the piezoelectric ceramics 22 and the moving coil actuator 32 can work simultaneously, the piezoelectric ceramics 22 is used for responding to the high-frequency part of the audio signal and pushing the screen 10 to generate vibration sound, and the moving coil actuator 32 is used for responding to the low-frequency part of the audio signal and pushing the screen 10 to generate vibration sound.
Referring to fig. 2, the control method according to the embodiment of the present application may be applied to an electronic device 100, where the electronic device 100 includes a screen 10, a piezoelectric ceramic 22, and a moving coil actuator 32, the piezoelectric ceramic 22 is connected to the screen 10, and the moving coil actuator 32 is connected to the screen 10; the control method comprises the following steps:
01: when the electronic device 100 is in the play-out mode, the piezoelectric ceramic 22 and the moving coil exciter 32 are controlled to work simultaneously, the piezoelectric ceramic 22 is used for responding to the high-frequency part of the audio signal and pushing the screen 10 to generate vibration sound, and the moving coil exciter 32 is used for responding to the low-frequency part of the audio signal and pushing the screen 10 to generate vibration sound.
In the electronic device 100 and the control method, the piezoelectric ceramic 22 responds to the high frequency and the moving coil exciter 32 responds to the low frequency, the two frequencies are complementary, and the screen 10 is driven to vibrate and sound in the whole audio frequency domain range, so that the external playing effect frequency domain is wider and more balanced.
Referring to fig. 3 and 4, the abscissa represents frequency and the ordinate represents frequency response. As can be seen from fig. 3, when the piezoelectric ceramic is used alone, the frequency response is poor at a low frequency; the use of a moving coil exciter alone results in a poor frequency response at higher frequencies. As can be seen from fig. 4, by using the technical solution of the present application, the frequency response of the low frequency and the high frequency is better, and no matter the piezoelectric ceramic or the moving coil exciter is used alone or the traditional moving coil loudspeaker is used alone, the frequency response of the technical solution of the present application is better, so that the frequency domain of the external playing effect is wider and more balanced.
The electronic device 100 may include a smart phone, a tablet computer, a smart watch, a smart bracelet, and the like, which are not limited herein. The electronic device 100 according to the embodiment of the present application is illustrated as a smart phone, and is not to be construed as a limitation to the present application.
The piezoelectric ceramics 22 can vibrate by the deformation generated by the inverse piezoelectric effect, thereby driving the screen 10 to vibrate and generate sound. The moving coil exciter 32 has a similar principle to the moving coil speaker, and specific examples thereof include: the changed current passes through the coil to generate a changed magnetic field, and the changed magnetic field acts with the magnetic field of the original magnet to generate vibration, so that the screen 10 is driven to vibrate and sound.
With continued reference to fig. 1, in some embodiments, the electronic device 100 further includes a circuit board 40, and the piezoelectric ceramics 22 and the moving coil actuator 32 may be disposed on the circuit board 40 and respectively connected to the screen 10. The circuit board 40 may include a first circuit board 42 and a second circuit board 44, wherein the first circuit board 42 may be a motherboard and disposed proximate to the first end 12 of the screen 10, and the second circuit board 44 may be a platelet and disposed proximate to the second end 14 of the screen 10. The piezoelectric ceramics 22 and the moving coil actuator 32 may both be provided on the first circuit board 42, or one of the piezoelectric ceramics 22 and the moving coil actuator 32 may be provided on the first circuit board 42 and the other on the second circuit board 44.
The electronic device 100 further comprises a middle frame 52, wherein the middle frame 52 is arranged between the screen 10 and the circuit board 40, a through hole is formed in the middle frame 52, the piezoelectric ceramics 22 and the moving coil exciter 32 can penetrate through the through hole to be connected with the screen 10 respectively, and therefore the piezoelectric ceramics 22 and the moving coil exciter 32 are not in contact with the middle frame 52, and sound is prevented from being dispersed to the periphery due to vibration of the middle frame 52.
The electronic device 100 further includes a battery 54, the battery 54 being used to power the screen 10, the piezoelectric ceramics 22, the moving coil actuator 32, the circuit board 40, and the like.

In some embodiments, a portion of the audio signal greater than a first preset frequency is determined as a high frequency portion, and a portion of the audio signal less than a second preset frequency is determined as a low frequency portion. The first preset frequency can be smaller than the second preset frequency, the high frequency can be medium-high frequency, and the low frequency can be medium-low frequency, so that the high frequency part and the low frequency part can be partially overlapped, and audio signal loss can be avoided. In one embodiment, the first predetermined frequency may be 1800HZ and the second predetermined frequency may be 2200HZ. The first preset frequency and the second preset frequency may be preset, or may be determined according to the specification parameters of the piezoelectric ceramic 22 and the specification parameters of the moving coil exciter 32, which is not specifically limited herein.
According to the embodiment of the application, the audio signal is divided, and the good low-frequency thrust in the moving coil exciter 32 is combined with the medium-high frequency ductility of the piezoelectric ceramic 22, so that the overall external playing effect of the screen 10 is improved. Specifically, when the electronic device 100 is in the play-out mode, the piezoelectric ceramics 22 and the moving coil exciter 32 are simultaneously driven to deform the screen 10, so that the screen 10 vibrates up and down, and air is pushed to generate sound.
Piezoelectric ceramic 22 and moving coil exciter 32 cooperate and use, can realize the outstanding power of putting outward of the full frequency channel of audio frequency, simultaneously when electronic equipment 100 is in putting the mode outward, through frequency division processing, piezoelectric ceramic 22 does not need to respond the low frequency part, moving coil exciter 32 does not need to respond the high frequency part, piezoelectric ceramic 22 and the difficult part that promotes of moving coil exciter 32 are filtered or are weakened, the frequency domain part that the performance is relatively poor of device itself has been avoided, therefore, do not need great power drive, greatly reduced holistic power consumption of putting outward.
In some embodiments, the electronic device 100 further includes a first filter for filtering out a low frequency portion of the audio signal to obtain a high frequency portion of the audio signal and outputting to the piezoelectric ceramic 22, and a second filter for filtering out a high frequency portion of the audio signal to obtain a low frequency portion of the audio signal and outputting to the moving coil exciter 32.

02: controlling the first filter to filter out the low frequency part of the audio signal to obtain the high frequency part of the audio signal and outputting the high frequency part to the piezoelectric ceramic 22;
03: the second filter is controlled to filter out the high frequency part of the audio signal to obtain the low frequency part of the audio signal and output to the moving coil exciter 32.
In this way, the high frequency part and the low frequency part of the audio signal can be obtained by the first filter and the second filter.
Specifically, when the electronic device 100 is in the play-out mode, the first filter and the second filter may perform frequency division processing on the audio signal, and when the piezoelectric ceramic 22 is tuned, considering that the low-frequency impedance of the piezoelectric ceramic 22 is large, the first filter may filter or weaken the low-frequency part, and only the high-frequency part (medium-high frequency signal) is reserved, so that the piezoelectric ceramic 22 may respond to the medium-high frequency signal of the audio signal and push the screen 10 to vibrate and sound; the moving coil exciter 32 can filter or weaken the high-frequency part due to large high-frequency impedance and large performance attenuation, and only the low-frequency part (medium and low frequency signal) is reserved, so that the moving coil exciter 32 can respond to the medium and low frequency signal of the audio signal and push the screen 10 to vibrate and sound.
Referring again to fig. 1, the first filter and the second filter may be integrated in the controller 60, and the controller 60 may be disposed on the circuit board 40.

Specifically, when the electronic device 100 is in the earpiece mode, the piezoelectric ceramic 22 and the moving coil exciter 32 can both drive the screen 10 to vibrate and generate sound in the whole audio frequency domain range, and therefore, the piezoelectric ceramic 22 or the moving coil exciter 32 can individually respond to the whole audio signal to reduce power consumption; it is also possible that the piezo-ceramic 22 and moving coil driver 32 work together to respond to the entire audio signal to boost loudness.
The piezoelectric ceramic 22 may be a combination of a speaker and a receiver, and the moving coil actuator 32 may be a combination of a speaker and a receiver, which is not limited herein.

042: at least one of the first power amplifier 26 and the second power amplifier 36 is addressed via the serial bus to be controlled for operation when the electronic device 100 is in the handset mode.
In this manner, operation of the piezoelectric ceramic 22 and/or the moving coil actuator 32 may be controlled depending on the mode of operation of the electronic device 100.
Specifically, when the electronic device 100 is in the play-out mode, the first power amplifier 26 and the second power amplifier 36 may be controlled to operate simultaneously by addressing via a serial bus (I2C), so that the piezoelectric ceramic 22 and the moving coil actuator 32 operate simultaneously, the piezoelectric ceramic 22 responds to a high-frequency portion of an audio signal and pushes the screen 10 to generate a vibration sound, and the moving coil actuator 32 responds to a low-frequency portion of the audio signal and pushes the screen 10 to generate a vibration sound.

Referring to FIG. 1, in some embodiments, a screen 10 includes first and second opposing ends 12, 14, a piezoceramic 22 and a moving coil actuator 32 both disposed proximate the first end 12; at least one of the piezoelectric ceramic 22 and the moving coil actuator 32 is operated when the electronic device 100 is in the earpiece mode.
In this manner, piezoelectric ceramic 22 and moving coil actuator 32 are both disposed proximate first end 12 to facilitate space distribution within electronic device 100.
Specifically, the first end 12 may be the top end of the screen 10, the second end 14 may be the bottom end of the screen 10, and when the electronic device 100 is in the earpiece mode, the user usually places the ear near the top end of the electronic device 100, so that the piezoelectric ceramic 22 and the moving coil exciter 32 are both disposed near the first end 12 (relative to the second end 14, disposed near the first end 12) to meet the normal usage habit of the user. Piezoelectric ceramic 22 and moving coil actuator 32 are both disposed proximate first end 12, and when electronic device 100 is in the earpiece mode, piezoelectric ceramic 22 or moving coil actuator 32 may respond to the entire audio signal individually to reduce power consumption; it is also possible that the piezo-ceramic 22 and moving coil driver 32 work together to respond to the entire audio signal to boost loudness. In one embodiment, piezoelectric ceramic 22 may be a combination of a boom-out and a boom-in, where moving coil actuator 32 is used with piezoelectric ceramic 22 only in boom-out mode, i.e., where piezoelectric ceramic 22 alone responds to the entire audio signal when electronic device 100 is in boom-in mode. In another embodiment, the moving coil actuator 32 may be a combination of a play and an earpiece, with the piezo ceramic 22 being used with the moving coil actuator 32 only in the play mode, i.e., with the moving coil actuator 32 alone responding to the entire audio signal when the electronic device 100 is in the earpiece mode.
In some embodiments, the screen 10 includes first and second opposing ends 12, 14, one of the piezoceramic 22 and moving coil activator 32 being disposed proximate the first end 12 and the other being disposed proximate the second end 14; when the electronic device 100 is in the earpiece mode, the piezo-ceramic 22 is active or the moving coil activator 32 is active.

044: when the electronic device 100 is in the earpiece mode, the operation of the piezoelectric ceramics 22 or the operation of the moving coil exciter 32 is controlled.
Thus, the piezoelectric ceramic 22 and the moving coil exciter 32 are separated from each other, so that a better sound effect can be achieved when the piezoelectric ceramic and the moving coil exciter are placed outside.

When the electronic device 100 is in the earpiece mode, only one of the piezoelectric ceramic 22 and the moving coil actuator 32 is required to operate, since the piezoelectric ceramic 22 and the moving coil actuator 32 are disposed at two separate ends. When the electronic device 100 is in the play mode, the piezoelectric ceramic 22 and the moving coil exciter 32 are disposed at two separated ends, so that the sounding positions of the two are different, and a better sound effect such as stereo sound can be achieved cooperatively.
