Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Electronic devices often produce sound through speakers, earphones, and the like, which often require openings in the electronic devices. On one hand, the product performance is reduced due to the open pores, and in order to achieve the appearance effect, various manufacturers try to reduce the size of the open pores, but the smaller the open pores are, the more the performance is affected; on the other hand, the screen accounts for the higher full screen user experience better, but because need keep certain panel region for the receiver realizes the vocal function, at the regional trompil of panel, can't realize full screen, influence user experience.

In addition, the display screen generally plays a role in an electronic device such as a mobile phone or a tablet computer to display contents such as 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.

With the increasing requirements of users on the definition and the fineness of displayed contents, more electronic devices adopt touch display screens with larger sizes to achieve the display effect of a full screen. 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 driving circuit outputs a high-low level driving signal to the exciter 131, the exciter 131 vibrates according to the driving signal, and the different electrical parameters of the driving signal output by the driving circuit may cause the different vibration parameters of the exciter 131, for example, the duty ratio of the driving signal corresponds to the vibration frequency of the exciter 131, and the amplitude of the driving signal corresponds to the vibration amplitude of the exciter 131.

The embodiment of the application provides a sound production method, which comprises the determination of a first sound production area and a second sound production area for producing sound. Specifically, referring to fig. 5, the method includes:

step S210: a sound signal is received.

Step S220: determining whether the sound signal is a target sound signal. If yes, go to step S230; if not, go to step S280.

In the embodiment of the application, not all sound signals can be played in the left and right channels, and when some left and right channels are played, the sound with better playing effect can be played in the left and right channels respectively. Therefore, in the embodiment of the present application, some target sound signals may be preset as sound signals for performing separate playback of left and right channels, and when a sound signal is received, it is determined whether the sound signal is the target sound signal, if so, the left channel signal and the right channel signal in the sound signal are obtained, and if not, the sound may be played as a whole without distinguishing the channels. As an embodiment, since the music signal is played better when being played in a left channel and a right channel, the target sound signal may be the music signal.

Step S230: and acquiring a left channel signal and a right channel signal in the sound signals.

In the embodiment of the application, the vibration component can comprise a screen and a shell, namely, the screen and the shell can vibrate and produce sound under the driving of the exciter. Therefore, in the case of receiving a sound signal, the screen or the housing can be selected to sound.

When the electronic device is placed on a surface of an object, such as a desktop, usually the screen is placed towards the object or the back cover is placed towards the object, and the screen or the back cover is in contact with the surface of the object and is shielded by the object. If the surface of the electronic device, which is in contact with the surface of the object, vibrates to generate sound, on one hand, the sound generating part of the electronic device may be affected by the contact object during vibration, and on the other hand, the generated sound may also be affected by the contact object during propagation. Therefore, the specific selection manner may be to determine whether the screen is occluded. If the screen is shielded, the screen can vibrate to sound through the shell, and particularly can vibrate to sound through the rear cover of the shell; if the screen is not shielded, the screen can be vibrated to sound. The method for determining whether the screen is blocked is not limited in the embodiment of the present application, and for example, the method is determined by a proximity sensor, or the method is determined by acquiring an image by a camera.

Of course, in the embodiment of the present application, it may also be determined that the screen or the casing vibrates to generate sound by determining whether the rear cover of the casing is shielded. If the rear cover is shielded, the sound is generated by the screen vibration, and if the rear cover is not shielded, the sound is generated by the shell vibration.

Step S250: a first sound emitting area and a second sound emitting area are determined in the sub-sound emitting areas of the shell.

In particular, the housing may comprise at least two sub sound emission areas. If the housing includes two sub-sound-emitting areas, the two sub-sound-emitting areas can be used as the first sound-emitting area and the second sound-emitting area, respectively. If the casing includes a plurality of sub-vocal areas, can select two sub-vocal areas from it as first vocal area and second vocal area respectively, perhaps, regard wherein partial sub-vocal area as first vocal area, partial sub-vocal area as second vocal area, the sub-vocal area as first vocal area is different with the sub-vocal area as second vocal area. Wherein, each sub-sound-emitting area can correspond to one exciter, or the sound emission is driven by a plurality of exciters. If a sub-sound-emitting area is driven to emit sound by a plurality of actuators, the plurality of actuators may be controlled in a unified manner.

Step S260: and determining a first sounding area and a second sounding area in the sub-sounding areas of the screen.

Specifically, the screen may include at least two sub-sound emission areas. If the screen includes two sub-sound-emitting areas, the two sub-sound-emitting areas can be respectively used as the first sound-emitting area and the second sound-emitting area. As shown in fig. 6, the screen includes a sub-sound-emission area a and a sub-sound-emission area B, a may be determined as the first sound-emission area, and B may be determined as the second sound-emission area. Of course, B may be determined as the first sound emission region and a may be determined as the second sound emission region. The positional relationship between the first sound emission region and the second sound emission region is not limited, and the regions at both ends of the diagonal line of the electronic device may be the first sound emission region and the second sound emission region, respectively.

If the screen includes a plurality of sub-sound production areas, can select two sub-sound production areas from it as first sound production area and second sound production area respectively, perhaps, regard wherein partial sub-sound production area as first sound production area, partial sub-sound production area is as second sound production area, and the sub-sound production area who is first sound production area is different with the sub-sound production area who is second sound production area. Wherein, each sub-sound-emitting area can correspond to one exciter, or the sound emission is driven by a plurality of exciters. If a sub-sound-emitting area is driven to emit sound by a plurality of actuators, the plurality of actuators may be controlled in a unified manner. For example, as shown in fig. 3, the screen includes sub-sound-emitting areas a, b, c, d, where a and b may be used as the first sound-emitting area, and c and d may be used as the second sound-emitting area; or a first sound emission region via a and d, and a second sound emission region via b and c, and the like, but the present embodiment is not limited thereto.

Optionally, in this embodiment of the application, if the screen is a vibration component capable of generating sound, the screen includes a plurality of sub-sound-generating areas, and the first sound-generating area and the second sound-generating area may be determined according to a central axis of the screen. The first sound emission area and the second sound emission area are respectively determined from the sub-sound emission areas on both sides of the screen lateral axis L1 as shown in fig. 7, for example; alternatively, as shown in fig. 6, the first sound emission area and the second sound emission area are respectively determined from sub-sound emission areas on both sides of the screen longitudinal axis L2.

Specifically, whether the electronic device is in the landscape screen state or the portrait screen state at present can be judged according to the posture of the electronic device. The electronic device is in a horizontal screen state or a vertical screen state, and can be obtained through detection of a sensor built in the electronic device, such as an accelerometer, a gyroscope, a gravity sensor and the like.

If the electronic device is in a landscape state, as shown in fig. 7, the user may hold the electronic device in a landscape manner, and two ends of the horizontal axis of the screen correspond to the left ear direction and the right ear direction of the user, respectively, so that the first sound emitting area and the second sound emitting area may be determined from the sub-sound emitting areas on two sides of the horizontal axis of the screen, as shown in fig. 7, the areas on two sides of the horizontal axis L1 may be determined as the first sound emitting area and the second sound emitting area, respectively. It is to be understood that, as described above, if the areas on both sides of the transverse axis L1 are a plurality of sub sound emission areas, one sub sound emission area may be taken from one side thereof as the first sound emission area, and one sub sound emission area may be taken from the other side thereof as the second sound emission area; or a plurality of sub-sound emission areas are taken from one side of the first sound emission area as a first sound emission area, and a plurality of sub-sound emission areas are taken from the other side of the first sound emission area as a second sound emission area.

Alternatively, which of the areas on both sides of the transverse axis is the first sound emitting area and which of the areas is the second sound emitting area may be determined according to which of the two side ends of the electronic device in the two transverse directions faces upward. The specific determination principle may be that the left end of the sound production area at the left end of the user is a first sound production area, and the sound production area at the right end of the user may be determined as a second sound production area. The specific determination manner is not limited in the embodiment of the present application, for example, as shown in fig. 7, when the side end D1 is set to face upward, the area close to the top end D1 is close to the right of the user and is a second sound production area; the area near the bottom end d2 is near the user's left, which is the first sound emanating area. When the side end D2 faces upwards, the area near the top end D1 is near the left of the user and is a first sound production area; the area near the bottom end d2 is near the user's right, which is the second sound emanating area.

If the electronic device is in the vertical screen state, as shown in fig. 6, a user may hold the electronic device in the vertical screen state, and the first sound emitting area and the second sound emitting area may be respectively determined from the sub-sound emitting areas on both sides of the screen longitudinal axis L2. The areas on both sides of the longitudinal axis L2 in fig. 6 may be defined as a first sound emission area and a second sound emission area, respectively.

Optionally, which of the areas on both sides of the longitudinal axis is the first sound emitting area and which is the second sound emitting area may be determined according to whether the top end of the electronic device faces upward or the bottom end of the electronic device faces upward in the longitudinal direction. The specific determination principle may be that the left end of the sound production area at the left end of the user is a first sound production area, and the sound production area at the right end of the user may be determined as a second sound production area. The specific determination manner is not limited in the embodiment of the present application, and for example, as shown in fig. 6, when the top end D1 is set upward in advance, the area near the side end D1 is near the left of the user and is the first sound generation area, and the area near the side end D2 is near the right of the user and is the second sound generation area.

In the embodiment of the application, the screen or the shell can be determined to sound according to whether the screen is shielded, and the first sound-emitting area and the second sound-emitting area of the screen can be set as default to sound.

Certainly, in the embodiment of the present application, the vibration component may also be only a screen or a casing, and if only the screen is used, the screen determines the first sound emitting area and the second sound emitting area to emit sound; if the shell is only used, the shell determines the first sound-emitting area and the second sound-emitting area to emit sound.

In the embodiment of the present application, the order between step S250 and step S260 is not limited. In addition, steps S240 to S260 may be after step S230, before step S220, or before step S210.

Step S270: driving the first sound-emitting area to emit sound through an exciter according to the left channel signal; and driving the second sounding area to sound through an exciter according to the right channel signal.

The occurrence area of the specific play may be the first sound emission area, the second sound emission area, or any area of the vibration member.

In another specific embodiment, if the left channel signal and the right channel signal cannot be obtained from the received sound signals, the sound signals may be played as a whole without distinguishing between the left channel and the right channel.
