It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein.

In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 2, an electronic device according to an embodiment of the present disclosure includes a supporting portion 100, a screen assembly 200, and an ultrasonic vibration module 300.

The supporting portion 100 may be an apparatus main body, a main board upper cover, or a housing, which is not limited in the embodiment of the present application. In the embodiment of the present application, the supporting portion 100 is provided with the mounting groove 120, specifically, the supporting portion 100 can be formed by injection molding, and the mounting groove 120 can be directly formed in the process; of course, after the support part 100 is prepared, the mounting groove 120 may be processed by a processing manner of removing material, such as a milling, etching, and chiseling. The mounting groove 120 may be a bar-shaped mounting groove, an L-shaped mounting groove, or an arc-shaped mounting groove.

The screen assembly 200 is disposed on the supporting portion 100, the screen assembly 200 covers the mounting groove 120, the supporting portion 100 and the screen assembly 200 form a mounting space, a first sound guiding area and a second sound guiding area are disposed at an interval in an area of the screen assembly 200 opposite to the mounting groove 120, or in other words, the screen assembly 200 has the first sound guiding area and the second sound guiding area, and the first sound guiding area and the second sound guiding area are disposed opposite to the mounting groove 120.

The ultrasonic vibration module 300 can emit two ultrasonic waves, and the two ultrasonic waves can be directionally propagated in the air by utilizing the high directivity of the ultrasonic waves, and simultaneously, the two ultrasonic waves are modulated into a plurality of sound waves due to the nonlinear modulation action of the air, wherein the frequency of the two ultrasonic waves emitted by the ultrasonic vibration module 300 is reasonably selected so that the difference frequency sound waves of the two ultrasonic waves are audible sound waves, for example, the ultrasonic vibration module 300 emits two ultrasonic waves with the frequencies of f1 and f2 and is influenced by the nonlinear interaction action of the air, the ultrasonic waves with the frequencies of f1 and f2 are modulated into a plurality of sound waves such as f1, f2, f1+ f2, f1-f2, 2f1 and 2f2, and f1-f2 are the difference frequency sound waves. The frequencies of f1 and f2 are reasonably selected, so that f1-f2 can be audible sound waves, for example, sound waves with the frequencies of f1=41khz, f2=40khz, f1-f2=1khz and 1khz belong to the audible sound waves, and the difference frequency sound waves obtained by the nonlinear mediation of two ultrasonic waves through air still have high directivity, so that the difference frequency sound waves can directionally propagate in the air, and further the sound can directionally propagate. The ultrasonic vibration module 300 is disposed on a side of the screen assembly 200 facing the supporting portion 100, and the ultrasonic vibration module 300 is located in the installation space, and the ultrasonic vibration module 300 is distributed opposite to the first sound guiding region. The sound emitted from the ultrasonic vibration module 300 located in the installation space can be propagated to the outside of the electronic apparatus through the first sound guide region or the second sound guide region.

Specifically, in a case where the first sound guiding region is not blocked, the ultrasonic waves emitted from the ultrasonic vibration module 300 are emitted outside the screen assembly 200 through the first sound guiding region; in the case where the first sound guiding region is blocked, the ultrasonic waves emitted from the ultrasonic vibration module 300 are emitted outside the screen assembly 200 through the second sound guiding region. This kind of mode can prevent to lead to the difficult transmission of the ultrasonic wave that ultrasonic vibration module 300 sent to the screen subassembly 200 outside because of the user presses screen subassembly 200 to make the ultrasonic wave that ultrasonic vibration module 300 sent lower in the loss of transmission in-process, and then make electronic equipment's sound production effect better.

In the specific use process of the electronic device, the hand of the user may block part of the screen assembly 200, and if the hand of the user just blocks the first sound guiding area, the electronic device can automatically detect and switch out the sound channel, so that the ultrasonic wave emitted by the ultrasonic vibration module 300 is emitted out of the screen assembly 200 through the second sound guiding area; the electronic device can also automatically detect if the first sound guiding region is not blocked by the user's hand, so that the ultrasonic waves emitted from the ultrasonic vibration module 300 are emitted out of the screen assembly 200 through the first sound guiding region.

In the electronic device disclosed in the embodiment of the application, the supporting portion 100 is provided with the mounting groove 120, the screen assembly 200 is disposed on the supporting portion 100, the supporting portion 100 and the screen assembly 200 form a mounting space, a region of the screen assembly 200 opposite to the mounting groove 120 has a first sound guiding region and a second sound guiding region which are distributed at intervals, the ultrasonic vibration module 300 is disposed on one side of the screen assembly 200 facing the supporting portion 100 and located in the mounting space, the ultrasonic vibration module 300 is distributed opposite to the first sound guiding region, and under the condition that the first sound guiding region is not blocked, the ultrasonic waves emitted by the ultrasonic vibration module 300 are emitted out of the screen assembly 200 through the first sound guiding region; in the case where the first sound guiding region is blocked, the ultrasonic waves emitted from the ultrasonic vibration module 300 are emitted outside the screen assembly 200 through the second sound guiding region. Under this kind of condition, electronic equipment can lead the regional sound production of sound through the second when first leading sound region is sheltered from, prevents that the sound production region of screen subassembly 200 from being sheltered from more easily, prevents to press screen subassembly 200 and lead to the difficult propagation of ultrasonic wave that ultrasonic vibration module 300 sent to outside screen subassembly 200 because of the user to the loss of ultrasonic wave in the propagation process that makes ultrasonic vibration module 300 send is lower, and then makes the effect of electronic equipment screen sound production better.

Under the better condition of effect at electronic equipment screen sound production, the ultrasonic wave that ultrasonic vibration module 300 sent can propagate outside screen component 200 better, propagate to the outer ultrasonic wave of screen component 200 outside the electronic equipment directional propagation, and directional propagation to answering the object, thereby make the directive property of electronic equipment screen sound production higher, in order that the sound that ultrasonic vibration module 300 sent can not propagate to the surrounding environment, avoid influencing the surrounding environment or being heard by other people, thereby improve the privacy of user's conversation, user's privacy is protected.

Therefore, the electronic equipment disclosed by the embodiment of the application can solve the problems that the directivity of sound is poor and a user can easily shield a screen sounding area in a screen sounding technology.

Further, the number of the sound guiding areas may be multiple, that is, the screen assembly 200 may further have a third sound guiding area, a fourth sound guiding area, a fifth sound guiding area, and the like thereon, so as to further prevent the user from easily blocking the sound emitting area of the screen assembly 200.

In this embodiment, the ultrasonic vibration module 300 and the first sound guiding region are distributed relatively, so that the ultrasonic vibration module 300 may be closer to the first sound guiding region and farther from the second sound guiding region, when the ultrasonic vibration module 300 sounds with a constant output power, there may be a situation where the sound pressure of the sound propagated to the outside of the screen assembly 200 through the first sound guiding region is greater than the sound pressure of the sound propagated to the outside of the screen assembly 200 through the second sound guiding region, which causes the sound pressure of the sound emitted by the electronic device to be inconsistent, and further causes poor user experience. Based on this, optionally, in a case where the first sound leading region is not occluded, the output power of the ultrasonic vibration module 300 may be the first power; in the case where the first sound leading region is blocked, the output power of the ultrasonic vibration module 300 may be the second power. The ultrasonic vibration module 300 adjusts the output power according to the shielding condition of the screen assembly 200, so that the sound pressure of the sound emitted by the electronic device is consistent, that is, the sound pressure of the sound transmitted to the outside of the screen assembly 200 by the ultrasonic vibration module 300 through the first sound guide region is the same as the sound pressure of the sound transmitted to the outside of the screen assembly 200 by the ultrasonic vibration module 300 through the second sound guide region, and further, the user experience is improved.

In general, the ultrasonic vibration module 300 is closer to the first sound leading region and farther from the second sound leading region, and thus the first power may be greater than the second power.

Of course, the distance between the ultrasonic vibration module 300 and the first sound guiding region and the distance between the ultrasonic vibration module 300 and the second sound guiding region may also be adjusted as appropriate, for example, the ultrasonic vibration module 300 may be disposed between the first sound guiding region and the second sound guiding region. In the case where the distance between the ultrasonic vibration module 300 and the first sound guiding region and the distance between the ultrasonic vibration module 300 and the second sound guiding region are equal to or not different from each other, the ultrasonic vibration module 300 may use the same power regardless of whether the sound is generated through the first sound guiding region or the second sound guiding region. Of course, in this case, if the first sound leading area and the second sound leading area are not simultaneously shielded, the ultrasonic vibration module 300 may simultaneously emit sound through the first sound leading area and the second sound leading area.

As described above, there are various ways to form the mounting groove 120, and alternatively, the support part 100 may have a raised support structure 110, and the support structure 110 may surround to form the mounting groove 120, and the screen assembly 200 may be disposed on the support structure 110 to form a closed mounting space. The mounting groove 120 is formed in a simple and reliable manner, and the support structure 110 is convenient to arrange, which is beneficial to reducing the design difficulty of designers. Meanwhile, the support structure 110 can stably support the screen assembly 200 and form an installation space, so that the ultrasonic waves are propagated in the installation space or an area of the screen assembly 200 opposite to the installation space, so that the ultrasonic waves are propagated to the second sound guide area, and the ultrasonic waves are prevented from being propagated to other areas, thereby improving the reliability of sounding the screen of the electronic device.

The ultrasonic waves emitted by the ultrasonic vibration module 300 have large loss when passing through the screen assembly 200, resulting in small sound pressure of sound emitted by the electronic device, or resulting in large output power of the ultrasonic vibration module 300. Based on this, in an alternative embodiment, the screen assembly 200 may include a display module 210 and a cover 220, the cover 220 may be disposed on the display module 210, and the display module 210 is located between the cover 220 and the supporting portion 100; a plurality of acoustic impedance matching units 400 may be disposed between the cover plate 220 and the display module 210, and the plurality of acoustic impedance matching units 400 may be respectively distributed opposite to the first sound guiding region and the second sound guiding region. The acoustic wave impedance matching part 400 can form an acoustic wave impedance matching layer with the screen assembly 200 and the external air, so that the ultrasonic wave is transmitted to the outside through the screen assembly 200 with a large efficiency, thereby reducing the loss of the screen assembly 200 to the ultrasonic wave, and further enabling the sound pressure of the sound emitted by the electronic device to be large when the output power of the ultrasonic vibration module 300 is small.

Specifically, the acoustic wave impedance of the acoustic wave impedance matching unit 400 is m, the acoustic wave impedance of the cover plate 220 is n, the acoustic wave impedance of air is e, and the acoustic wave impedance m of the acoustic wave impedance matching unit 400 satisfies: m = n ² And e is as follows. The acoustic wave impedance matching section 400 satisfying the above formula can further reduce the loss of the screen assembly 200 to the ultrasonic waves, thereby enabling the ultrasonic waves to be propagated to the outside through the screen assembly 200 with greater efficiency. The acoustic wave impedance matching unit 400 may be a light-transmitting unit, so as to avoid affecting the normal display of the screen assembly 200. Of course, the acoustic impedance matching unit 400 may be disposed in the mounting groove 120 to reduce the loss of the ultrasonic wave propagating in the mounting groove 120.

In order to further improve the sound production effect of the electronic device, in an optional embodiment, the number of the mounting grooves 120 may be multiple, the number of the ultrasonic vibration modules 300 may be equal to the number of the mounting grooves 120, and the screen assembly 200 and the mounting grooves 120 may form a plurality of mounting spaces, the ultrasonic vibration modules 300 may be disposed in the mounting spaces in a one-to-one correspondence manner, so that the electronic device has the ultrasonic vibration modules 300, and the ultrasonic vibration modules 300 produce sound through a plurality of areas on the screen assembly 200, so that the ultrasonic vibration modules 300 with a large number can make the sound directionality higher, and the transmission efficiency higher.

Alternatively, the number of the ultrasonic vibration modules 300 may be four, and the four ultrasonic vibration modules 300 may be respectively arranged in four corner regions of the screen assembly 200, where the four corner regions of the screen assembly 200 refer to four diagonal regions of the electronic device. Of course, the four ultrasonic vibration modules 300 may be respectively arranged at four edge regions of the screen assembly 200, where the four edge regions of the screen assembly 200 refer to four side regions of the electronic device. The arrangement mode of the ultrasonic vibration module 300 can enable the stereo effect of the electronic equipment to be good, so that the use experience of a user can be improved.
