While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

under the condition that voltage is applied to the electric vibration plate 2, the electric vibration plate 2 deforms and drives the display screen 1 to vibrate.
The display screen 1 mainly plays a role in displaying, and also has one or more functions of reminding, navigation, interaction and the like. The electric vibrating reed 2 is an actuator element for controlling vibration by applying voltage, the electric vibrating reed 2 is attached to the back surface of the display screen 1, that is, the display screen 1 faces the surface inside the accommodating cavity, as shown in fig. 2, by applying alternating voltage to the electric vibrating reed 2, the electric vibrating reed 2 can be continuously bent and deformed up and down along with the change of the voltage, and the deformation is transmitted to the display screen 1 to drive the display screen 1 to vibrate, so that the screen can sound.
Wherein, the number of the electrogenerated vibrating reeds 2 is at least 1, so as to meet the requirement of sound production performance.

Optionally, the electric vibrating piece 2 is an ion conduction vibrating piece. The ion conduction vibration plate is a composite material actuator element in which gold is formed as an electrode on an ion exchange resin by special electroless gold plating, and displacement performance is greatly improved by making the electrode surface area large. By applying a voltage, cations in the polymer electrolyte within the ion-conducting vibrating piece move to the cathode side, causing a difference in swelling of the front and back sides and deformation. The ion conduction vibrating plate is applied with alternating voltage, the ion conduction vibrating plate can be continuously bent and deformed up and down along with the change of the voltage, deformation is transmitted to the screen, and the screen is driven to vibrate, so that the screen can sound. The ion conduction vibration plate may have a vibration amplitude covering from 0.1mm to 10mm, the vibration amplitude being related to a thickness of the ion conduction vibration plate and a magnitude of the applied voltage, and the magnitude of the vibration amplitude may be controlled by controlling the thickness of the ion conduction vibration plate and the applied voltage.
The electric conduction vibrating reed 2 is an ion conduction vibrating reed, has the advantages of small size, quick response time and convenience in installation, and can reduce the occupied space while meeting the performance of electronic equipment.
Alternatively, in the case where a first voltage is applied to the electric vibrating piece 2, the electric vibrating piece 2 is deformed in a first direction; in the case where a second voltage is applied to the electric vibrating piece 2, the electric vibrating piece 2 is deformed in a second direction;
the first direction and the second direction are opposite directions, and the polarities of the first voltage and the second voltage are opposite.
As shown in fig. 3, the state of the electric vibrating reed 2 when no voltage is applied is schematically shown, and both the electric vibrating reed 2 and the display panel 1 are in a normal state and are not deformed. When a first voltage is applied to the electric vibrating reed 2, as shown in fig. 4, cations in the electric vibrating reed 2 move toward a first direction, and then the electric vibrating reed 2 deforms along the first direction and drives the display screen 1 to deform toward the first direction; when a second voltage with opposite polarity is applied to the electric vibrating reed 2, as shown in fig. 5, the cations in the electric vibrating reed 2 move toward a second direction, so that the electric vibrating reed 2 deforms along the second direction, and drives the display screen 1 to deform toward the second direction.
In this embodiment, when power is not supplied to the electric vibrating reed 2, the electric vibrating reed 2 is attached to the back of the display screen 1, when a voltage which changes alternately is applied to the electric vibrating reed 2, the electric vibrating reed 2 deforms alternately, and along with the change of the voltage, the electric vibrating reed 2 continuously bends and deforms up and down, and the deformation is transmitted to the display screen 1 to drive the display screen 1 to vibrate in a deformation manner, so that air is pushed to generate sound, and a screen sounding function is achieved.
Alternatively, as shown in fig. 6, the electric vibrating piece 2 includes: the vibrating reed comprises a vibrating reed body 21, wherein a polymer electrolyte is arranged in the vibrating reed body 21, cations in the polymer electrolyte move to different directions along with the change of voltage polarity, and the vibrating reed body 21 can be made of ion exchange resin; a first electrode layer 22 provided on a first surface of the resonator element body 21; the first surface may be a surface attached to the display screen 1.
A second electrode layer 23 provided on a second surface of the resonator element body 21, the first surface and the second surface being opposite surfaces; the first electrode layer 22 and the second electrode layer 23 may be formed by plating gold on an ion exchange resin by a special electroless gold plating method, and the second surface may be a surface of the vibrating reed body 21 away from the display panel 1.
An insulating plate connecting the first electrode layer 22 and the second electrode layer 23; and a driving circuit 25 disposed on an outer surface of the insulating plate, wherein the driving circuit 25 is electrically connected to the first electrode layer 22 and the second electrode layer 23, respectively. The insulating plate is used for connecting two ends of the first electrode layer 22 and the second electrode layer 23, and is disposed on two side surfaces of the vibrating piece body 21 as shown in fig. 6; the driving circuit 25 is disposed outside the insulating plate, and mainly functions to supply power to the electrodes of the electric vibrating reed 2, thereby driving the electric vibrating reed 2 to deform.
In this embodiment, the driving circuit 25 is connected to the first electrode layer 22 and the second electrode layer 23, and supplies power to the electric vibrating reed 2, so that the electric vibrating reed 2 can deform toward the first direction under the action of a first voltage and deform toward the second direction under the action of a second voltage, and under the action of the alternating voltage, the electric vibrating reed 2 deforms alternately and drives the display screen 1 to deform and vibrate, thereby pushing air to generate sound and realizing screen sounding.
Alternatively, as shown in fig. 6, the insulating plates include a first insulating plate 241 and a second insulating plate 242; the first insulating plate 241 covers the third surface of the vibrating reed body 21, and the second insulating plate 242 covers the fourth surface of the vibrating reed body 21; the third surface is adjacent to the first surface and the second surface, and the fourth surface is adjacent to the first surface and the second surface.
The first insulating plate 241 is used for connecting a first end of the first electrode layer 22 and a first end of the second electrode layer 23; the second insulating plate 242 is used to connect the second end of the first electrode layer 22 and the second end of the second electrode layer 23.
The insulating plates are provided at both ends of the first electrode layer 22 and the second electrode layer 23 for connecting both ends of the two electrodes, respectively, and a driving circuit is provided on the insulating plates to apply a voltage to the first electrode layer 22 and the second electrode layer 23.
Optionally, the first surface of the vibrating reed body 21 is attached to the surface of the display screen 1. The first surface provided with the first electrode layer 22 is directly attached to the surface of the display screen 1 facing the accommodating cavity, so that the space occupied by the driving circuit can be reduced. When the electric vibration plate 2 is an ion conduction vibration plate, the volume of the ion conduction vibration plate is smaller, and the vibration plate body of the ion conduction vibration plate is attached to the surface of the display screen 1, so that the occupied space of a sound production device can be saved; in addition, the one side that the trembler body has the electrode directly attached in the bottom surface of display screen 1 can save drive circuit's occupation space, consequently, this application embodiment can be under the condition of cancellation electronic equipment trompil, when guaranteeing electronic equipment sound production, further save sound generating mechanism's occupation space.
The electric vibrating piece 2 may be square, circular, or ring-shaped (e.g., square ring or circular ring). Taking the square shape of the electroluminescent vibrating reed 2 as an example, optionally, the electroluminescent vibrating reed 2 is a long strip shape, as shown in fig. 1, the long strip-shaped electroluminescent vibrating reed 2 is attached to the surface of the display screen 1, when an alternating voltage is applied to the electroluminescent vibrating reed 2, the long strip-shaped electroluminescent vibrating reed 2 is alternately deformed, and along with the voltage change, the electroluminescent vibrating reed 2 drives the display screen 1 to continuously bend and deform up and down to generate vibration, so as to realize screen sounding.
Taking the example that the electric vibrating reed 2 is circular, alternatively, the electric vibrating reed 2 is circular, as shown in fig. 7, the electric vibrating reed 2 is provided in a circular shape. As shown in fig. 8, the state of the disk-shaped electric field vibrating reed 2 when no voltage is applied is schematically shown, and neither the electric field vibrating reed 2 nor the display panel 1 is deformed. When a first voltage is applied to the electric vibrating reed 2, as shown in fig. 9, the disc-shaped electric vibrating reed 2 deforms along the first direction, and drives the display screen 1 to deform towards the first direction; when a second voltage with opposite polarity is applied to the electric vibrating reed 2, as shown in fig. 10, the disc-shaped electric vibrating reed 2 deforms along the second direction, and drives the display screen 1 to deform towards the second direction.
The disc-shaped electroproduction vibrating reed 2 can better drive the whole screen to deform and vibrate relative to the strip-shaped electroproduction vibrating reed 2, and then the effect of screen sounding is improved.
Wherein, the number of the electric vibrating piece 2 is at least one, optionally, the number of the electric vibrating piece 2 is at least two. When the number of the at least two electric vibrating reeds 2 is at least two, the at least two electric vibrating reeds 2 are arranged in a preset regular manner. The preset rule can be set according to requirements, for example, in order to enable the top end of the screen to sound clearly, the electric vibrating reed 2 with high density can be arranged at a position close to the top end of the screen.
Optionally, when there are at least two of the electric vibrating reeds 2, the at least two electric vibrating reeds 2 are uniformly spaced from the first end to the second end of the display panel 1. Taking the shape of the electric vibrating reed 2 as a long strip and three electric vibrating reeds 2 as an example, as shown in fig. 11, the three electric vibrating reeds 2 are sequentially arranged at a predetermined interval and attached to the surface of the display screen. It should be noted that at least two of the electric vibrating reed 2 may be arranged in a transverse direction, a longitudinal direction, or an arrangement rule according to a requirement.
When the number of the electric vibrating reeds 2 is at least two, the polarities of the voltages applied to the at least two electric vibrating reeds 2 are the same, so that the at least two electric vibrating reeds 2 vibrate in the same direction, and a clearer sound is generated, so that a user can hear the clearer sound everywhere on the screen.
The electric vibrating reed 2 is arranged regularly and can be arranged at any position of the surface of the display screen 1 facing the containing cavity, so that when a user receives sound (for example, when the user answers a call), the ear is close to any screen at will, and the user can hear sound with high tone quality, and the user can receive the sound conveniently and the sound production effect is clearer.
Alternatively, when the number of the electric vibrating reed 2 is at least three, the number of the electric vibrating reed 2 disposed in the center area of the display screen 1 is larger than the number of the electric vibrating reed 2 disposed in the edge area of the display screen 1. Thus, the number of the electric vibrating reeds 2 in the central area of the screen is larger, and the number of the electric vibrating reeds 2 in the edge position is smaller, so that the vibration in the central position of the screen is stronger, and the sound production in the central area of the screen is clearer.
Alternatively, the thickness of the electric vibrating reed 2 is related to the position where the electric vibrating reed 2 is disposed on the display screen 1, and the display screen 1 may include a central region and an edge region, wherein the thickness of the electric vibrating reed 2 in the central region is smaller than the thickness of the electric vibrating reed 2 in the edge region, or the thickness of the electric vibrating reed 2 in the central region is larger than the thickness of the electric vibrating reed 2 in the edge region. For example: the user needs to make clear sound at the center of the screen, and the sound at the edge of the screen can be slightly worse, so that the thin electric vibrating reed 2 can be arranged at the center of the display screen 1, and the thick electric vibrating reed 2 is arranged at the edge of the display screen 1. The thickness of the electric vibrating reed 2 at different positions is set according to the sounding requirement, so that the vibration strength of different positions of the screen can be different.
Optionally, the electric vibrating reed 2 is a ring structure, one end of the ring structure is connected to the display screen 1, and the other end of the ring structure is connected to the housing, that is, the electric vibrating reed 2 is attached to the display screen 1 and the housing at the same time. The electric vibrating reed 2 is arranged to be of an annular structure and is simultaneously connected with the display screen 1 and the shell, so that when voltage is applied to the electric vibrating reed 2, the electric vibrating reed 2 can drive the display screen 1 and the shell to vibrate and sound at the same time, and vibration sense of the whole machine is consistent.
Alternatively, when the driving circuit detects that sound is required to be generated, an alternating voltage is applied to the electric vibrating reed 2, and the amplitude of vibration of the electric vibrating reed 2 can be controlled by controlling the magnitude of the voltage, for example: the larger the voltage applied to the electric vibrating reed 2 by the driving circuit is, the larger or smaller the amplitude of the vibration of the electric vibrating reed 2 is. The larger the vibration amplitude of the electric vibrating piece 2 is, the clearer the screen sounds, and the smaller the vibration amplitude is, the smaller the sound made by the screen is. The vibration rate of the electric vibrating reed 2 is also related to the voltage, for example, the larger the voltage applied to the electric vibrating reed 2 by the driving circuit, the larger or smaller the corresponding vibration rate.
Taking the example that the larger the applied voltage is, the larger the vibration amplitude of the electric vibrating reed 2 is, and the larger the sound emitted by the screen is, when the user adjusts the volume, the electronic device receives the operation of the user on the volume control, and controls the magnitude of the voltage applied to the electric vibrating reed 2 by the driving circuit, for example: when a user clicks a volume increasing button, the voltage applied to the electric vibrating reed 2 by the driving circuit is controlled to be increased; when the user clicks the volume reduction button, the voltage applied to the electric vibrating reed 2 by the driving circuit is controlled to be reduced.
Alternatively, as shown in fig. 12, the display screen 1 includes: a cover plate 11 and a touch screen 12; the at least one electric vibrating reed 2 is attached to the surface of the touch screen 12 facing the inside of the electronic device; the cover plate 11 is disposed on a surface of the touch screen 12 facing the outside of the electronic device. The cover plate 11 is used for protecting the touch screen 12 and preventing the touch screen 12 from being damaged under stress. The touch screen 12 may be an inductive liquid crystal display device capable of receiving input signals such as a touch.
As shown in fig. 12, the electronic device further includes: the middle frame 3 is arranged on one side, far away from the display screen 1, of the electric vibrating reed 2 and mainly plays a role in connection and fixation. The electronic device further includes: the battery 4 provides power for operation of the electronic device, and the battery cover 5 mainly plays a role in protecting the electronic device.
The embodiment of this application sets up at least one electrogenic trembler through the inside one side of the orientation electronic equipment at the display screen, gives electrogenic trembler applys voltage and makes it produce deformation to drive display screen deformation vibration sound production, for traditional speaker sound production, this application cancellation earphone structure need not the trompil on electronic equipment and can realize the sound production, can enough realize electronic equipment's waterproof dustproof function, can realize comprehensive screen design again.
