The display screen generally plays a role in an electronic device such as a mobile phone or a tablet computer to display text, pictures, icons, or video. With the development of touch technologies, more and more display screens arranged in electronic devices are touch display screens, and when a user is detected to perform touch operations such as dragging, clicking, double clicking, sliding and the like on the touch display screen, the touch operations of the user can be responded under the condition of arranging the touch display screens.

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. After a series of researches, the inventor finds that sound can be emitted by controlling the screen, the frame or the rear cover of the mobile phone to vibrate, so that the arrangement of the sound outlet hole of the receiver can be eliminated.

The specific sound emission control method is described in detail in the following embodiments.

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 detecting the pressure value acting on the screen and automatically adjusting the sound production volume of the screen according to the pressure value so as to improve the convenience of volume adjustment and reduce the loss of a volume key. In a specific embodiment, the sound emission control method is applied to the sound emission control device 300 shown in fig. 8 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:

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.

Further, after the current pressure value is obtained, a current volume value corresponding to the current pressure value of the electronic device is obtained based on the current pressure value, wherein the current volume value can be calculated in real time through the current pressure value according to a preset algorithm, or a corresponding relationship between a plurality of pressure values and a plurality of volume values can be preset, and the current volume value corresponding to the current pressure value and the like can be searched from the corresponding relationship. Specifically, the current volume value may be obtained by adjusting a volume value of the electronic device at a previous time according to the current pressure value, where the volume value at the previous time may be a volume value of the electronic device before the current volume value is obtained, and as a manner, the current pressure value is positively correlated with the current volume value, that is, the larger the current pressure value is, the larger the current volume value is; the smaller the current pressure value, the smaller the current volume value.

Step S130: and controlling the exciter to drive the screen to vibrate and sound according to the current volume value.

In the embodiment, after the current volume value is determined, the exciter is controlled to drive the screen to vibrate and emit sound according to the current volume value. Specifically, when the current volume value is greater than the volume value at the previous moment, the electronic device controls the exciter to increase the volume of the screen sounding, when the current volume value is equal to the volume value at the previous moment, the electronic device controls the exciter to keep the volume of the screen sounding, and when the current volume value is less than the volume value at the previous moment, the electronic device controls the exciter to decrease the volume of the screen sounding, so that the volume of the electronic device is adjusted according to touch operation acting on the screen, the convenience of volume adjustment is improved, and the loss of volume keys is reduced.
