As the user demands higher definition and higher fineness of the displayed content, more electronic devices employ touch display screens with larger sizes. However, in the process of setting a touch display screen with a large size, it is found that functional devices such as a front camera, a proximity optical sensor, and a receiver, which are disposed at the front end of the electronic device, affect an area that the touch display screen can extend to.

Generally, an electronic device includes a front panel, a rear cover, and a bezel. The front panel includes a forehead area, a middle screen area and a lower key area. Generally, the forehead area is provided with a sound outlet of a receiver and functional devices such as a front camera, the middle screen area is provided with a touch display screen, and the lower key area is provided with one to three physical keys. With the development of the technology, the lower key area is gradually cancelled, and the physical keys originally arranged in the lower key area are replaced by the virtual keys in the touch display screen.

The earphone sound outlet holes arranged in the forehead area are important for the function support of the mobile phone and are not easy to cancel, so that the difficulty in expanding the displayable area of the touch display screen to cover the forehead area is high.

Examples

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a first sound emission control method according to an embodiment of the present application. The sound production control method is used for enhancing the sound production effect of the screen by detecting the pressure value acting on the screen and automatically adjusting the vibration parameters of the screen according to the pressure value. In a specific embodiment, the sound emission control method is applied to the sound emission control device 300 shown in fig. 7 and the electronic device 100 (fig. 1 and 2) equipped with the sound emission control device 300. The specific process of the present embodiment will be described below by taking an electronic device as an example, and it is understood that the electronic device applied in the present embodiment may be a smart phone, a tablet computer, a wearable electronic device, and the like, which is not limited herein. As will be described in detail with respect to the flow shown in fig. 4, the sound production control method may specifically include the following steps:

step S110: when the electronic device is in a screen sounding mode, touch operation acting on the screen is detected, wherein in the screen sounding mode, the exciter drives the screen to vibrate and sound.

In this embodiment, the screen of the electronic device may be used for vibration sound generation, and is suitable for a non-headset call mode of the electronic device, where the non-headset call mode includes a hands-free mode and an earpiece mode, and is used for playing a voice signal sent by the electronic device during a call, playing a video, and the like. In this embodiment, when the electronic device is in the non-earphone mode, the electronic device may be set to the screen sound emission mode by default, or the user may select whether to set the screen sound emission mode by himself, which is not limited herein. It is understood that the electronic device may include a speaker mode, etc. in addition to the screen sound emission mode, in which sound is emitted by the vibration of the speaker.

As one manner, whether the electronic device is in the screen sound production mode during a call or playing a video, or not, specifically, whether the electronic device is connected with an earphone may be determined first, where the determination may be made by checking a state of an earphone connection hole of the electronic device, for example, when the earphone connection hole of the electronic device is connected with the earphone, a first state value is returned, when the earphone in the connection hole is pulled out, a second state value is returned, and whether the current electronic device is connected with the earphone may be determined by detecting the first state value and the second state value. As a mode, the Android system sends a broadcast when the earphone is plugged into and unplugged from the connection hole, so the electronic device can determine whether the earphone is currently connected by monitoring the broadcast, and thus, can determine whether the electronic device is in an earphone call mode. Further, when it is determined that the electronic apparatus is in the non-headset call mode, the electronic apparatus is in the earpiece mode or the handsfree mode, and thus, the electronic apparatus may be considered to be in the screen sound emission mode at this time.

Alternatively, since the screen is driven to emit sound by the actuator in the screen-emission mode, it is possible to determine whether the electronic apparatus is in the screen-emission mode by detecting the state of the actuator. Specifically, the state of the exciter is detected, wherein when the exciter is detected to be in the working state and the screen is driven to vibrate, the electronic device can be considered to be in the screen sounding mode.

In this embodiment, when a touch operation on the screen is detected, for example, when a pressing force on the screen is detected to exceed a preset force, the normal vibration sound production of the screen is influenced by the representation of the touch operation, and therefore, a current pressure value of the touch operation can be detected by a pressure sensor disposed below the screen.

Further, after the current pressure value is obtained, a current vibration parameter corresponding to the current pressure value of the electronic device is obtained based on the current pressure value, wherein the current vibration parameter can be calculated according to a preset algorithm through the current pressure value in real time, a corresponding relationship between a plurality of pressure values and the plurality of vibration parameters can be preset, and the current vibration parameter corresponding to the current pressure value and the like can be searched from the corresponding relationship. Specifically, the current vibration parameter may be obtained by adjusting a vibration parameter of the electronic device at a previous time according to the current pressure value, where the vibration parameter at the previous time may be a vibration parameter of the screen before the current vibration parameter is obtained, for example, according to the current pressure value, at least one of a vibration amplitude or a vibration frequency of the screen is increased to obtain the current vibration parameter, so as to counteract an influence of the touch operation on a vibration sound of the screen.

Step S130: and controlling the exciter to drive the screen to vibrate and sound according to the current vibration parameters.

In the embodiment, after the current vibration parameters are determined, the exciter is controlled to drive the screen to sound according to the current vibration. Specifically, when the current vibration parameter increases the vibration amplitude of the screen, controlling the exciter to drive the screen to increase the vibration amplitude to sound; when the current vibration parameter increases the vibration frequency of the screen, controlling the exciter to drive the screen to increase the vibration frequency to sound; when the current vibration parameter simultaneously increases the vibration amplitude and the vibration frequency of the screen, the exciter is controlled to drive the screen to increase the vibration amplitude and the vibration frequency to sound and the like, so that the vibration parameter of the screen is automatically adjusted according to touch operation acting on the screen, and the sound effect of the screen is enhanced.

The first sound production control method provided by the embodiment of the application detects touch operation acting on a screen when an electronic device is in a screen sound production mode, wherein in the screen sound production mode, the exciter drives the screen to vibrate and produce sound, the current pressure value of the touch operation is acquired, the current vibration parameter of the electronic device is obtained based on the current pressure value, the exciter is controlled to drive the screen to vibrate and produce sound according to the current vibration parameter, and therefore the pressure value acting on the screen is detected, and the vibration parameter of the screen is automatically adjusted according to the pressure value, so that the screen sound production effect is enhanced.

In this embodiment, the screen includes a plurality of sound emission areas, and the exciter has a plurality of vibration units disposed corresponding to the plurality of sound emission areas, where the size relationship and the positional relationship of the plurality of sound emission areas are not limited herein.

Further, when the pressure value of the touch operation is obtained, the current touch position of the touch operation is detected at the same time, and it can be understood that, because the screen of the electronic device is a touch display screen, the screen can detect the touch operation acting on each position of the screen and correspondingly obtain the current touch position of the touch operation, as a way, the coordinate position information of each touch point of the touch operation can be obtained.

As the screen includes a plurality of sound emission areas, the current touch position may be located in a certain sound emission area or in some sound emission areas, and as a manner, coordinate position information of each touch point of the touch operation is first obtained, and then the coordinate position information of each touch point is compared with coordinate information of an enclosed area formed by the plurality of sound emission areas to obtain the enclosed area where each touch point is located, so that a target sound emission area in the plurality of sound emission areas corresponding to the current touch position may be obtained.

As a manner, when the current touch position corresponds to at least two sounding areas in the multiple sounding areas, a touch enclosing area of the current touch operation may be obtained, a calculation is performed based on the touch enclosing area, and a center position of the touch enclosing area is obtained, where the center position is a touch center position of the current touch position, a sounding area where the touch center position is located is obtained, and the sounding area is determined as a target sounding area.

Further, after the target sound production area is determined, the current vibration parameter of the target sound production area is obtained based on the current pressure value, and it can be understood that when the screen includes a plurality of sound production areas, the touch operation of the user only affects the vibration sound production of the sound production area of the touch position of the user, so that in the embodiment, the vibration parameter of the target sound production area can be independently adjusted according to the current pressure value, and the adjustment effect is improved.

As another mode, when the number of the target sound emission areas is multiple, the current pressure value on each target sound emission area in the multiple sound emission areas can be detected respectively, the current vibration parameter corresponding to each sound emission area is obtained according to the current pressure value on each sound emission area, and then each sound emission area is controlled to emit sound according to the current vibration parameter of each sound emission area.
