It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The technical scheme disclosed by each embodiment of the invention is described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 4, an embodiment of the present invention discloses a protective cover for an electronic device, and the disclosed protective cover includes a body portion 200 and an ultrasonic directional sound emitting device 300.
The body portion 200 is provided with a receiving slot 230, the electronic device 100 may be disposed in the receiving slot 230, and the electronic device 100 is generally engaged with the receiving slot 230, when the electronic device 100 needs to be separated from the receiving slot 230, a user only needs to apply a larger separating force to the electronic device 100 and the receiving slot 230, so that the electronic device 100 can be separated from the receiving slot 230, when the electronic device 100 does not need to be separated from the receiving slot 230, the electronic device 100 needs to be relatively stably engaged with the receiving slot 230, so that the protective sleeve can protect the electronic device 100, and the electronic device 100 is prevented from being knocked.
The body portion 200 is a base member of the protective case, and the body portion 200 can provide a mounting base for other components of the protective case. The body portion 200 is provided with an electrical connection portion 210, the electrical connection portion 210 is electrically connectable to the electronic device 100, the ultrasonic directional sound emitting device 300 is provided on the body portion 200, and the ultrasonic directional sound emitting device 300 is electrically connected to the electrical connection portion 210, and when the electronic device 100 is provided in the accommodation groove 230, the ultrasonic directional sound emitting device 300 is electrically connected to the electronic device 100 through the electrical connection portion 210.
The ultrasonic directional sound emitting device 300 can emit at least two ultrasonic waves, the at least two ultrasonic waves can be directionally transmitted in the air by utilizing the high directivity of the ultrasonic waves, and meanwhile, the at least two ultrasonic waves are mediated into a plurality of sound waves due to the nonlinear mediation effect of the air, wherein the frequency of the at least two ultrasonic waves emitted by the ultrasonic directional sound emitting device 300 is reasonably selected so that the difference frequency sound wave of the at least two ultrasonic waves is an audible sound wave, for example, the ultrasonic directional sound emitting device 300 emits two ultrasonic waves with the frequencies of f1 and f2, and the two ultrasonic waves with the frequencies of f1 and f2 are mediated into a plurality of sound waves such as f1, f2, f1+f2, f1-f2, 2f 1-f2 and the like under the influence of the nonlinear interaction of the air, wherein f1-f2 is the difference frequency sound wave. The frequencies of f1 and f2 are reasonably selected, so that f1-f2 can be an audible sound wave, for example, f1=41 khz, f2=40 khz, f1-f2=1 khz and 1khz of the sound wave belong to the audible sound wave, and the difference frequency sound wave obtained by performing nonlinear air mediation on two ultrasonic waves still has high directivity, so that the difference frequency sound wave can directionally propagate in the air, and further sound can directionally propagate.
In a specific working process, when a user needs private conversation or in order to avoid affecting the surrounding environment, the user only needs to adjust the sound emitting direction of the ultrasonic directional sound emitting device 300 so that the sound emitting direction of the ultrasonic directional sound emitting device 300 faces the user, at this time, the sound emitted by the electronic equipment through the ultrasonic directional sound emitting device 300 can be directionally transmitted to the position where the user is located, the sound cannot be transmitted to the surrounding environment, the surrounding environment is prevented from being affected or heard by other people, and therefore the conversation privacy of the user is improved, and the privacy of the user is protected.
Of course, the user can also use the telephone receiver to carry out private call, when the user uses the telephone receiver to carry out private call, the ear of the user is close to the telephone receiver hole 150 to hear the sound, and the sound emitted by the telephone receiver is difficult to spread to the surrounding environment due to the characteristics of the telephone receiver, so that the sound emitted by the telephone receiver can only be heard by the ear of the person close to the telephone receiver hole 150, thereby avoiding affecting the surrounding environment or being heard by other people, and further improving the privacy of the user call,
When the user needs to play the sound, for example, the user and the friend talk together with a remote parent or friend, or the user and the friend enjoy songs or movie works together, the user can open a speaker of the electronic device 100 to play the sound, so that the user and the friend talk together with the remote parent or friend, or the user and the friend can enjoy songs or movie works together, and further user experience is improved.
In the protective case of the electronic device disclosed in the embodiment of the present invention, the electronic device 100 may be disposed in the accommodating groove 230, the ultrasonic directional sound emitting device 300 is disposed in the body portion 200 and is electrically connected to the electrical connection portion 210, and the ultrasonic directional sound emitting device 300 is electrically connected to the electronic device 100 through the electrical connection portion 210. The protective sleeve can provide an installation position for the ultrasonic directional sounding device 300, so that the situation that the electronic equipment 100 is not provided with enough space layout ultrasonic directional sounding device 300 due to small size of the electronic equipment 100 is prevented, the body part 200 is provided with more positions or space layout ultrasonic directional sounding devices 300, holes can be prevented from being formed in the shell of the electronic equipment 100, the appearance attractive performance of the electronic equipment 100 is improved, and the electronic equipment 100 is enabled to be good in integration, so that user experience is improved. Finally, the problems that the directional loudspeaker array with insufficient space layout in the electronic equipment and the electronic equipment are poor in integrity are solved.
Meanwhile, the ultrasonic directional sound emitting device 300 can be electrically connected with the electronic apparatus 100 through the electrical connection part 210, so that the electronic apparatus 100 can directionally propagate sound through the ultrasonic directional sound emitting device 300, thereby ensuring that the electronic apparatus 100 has an audio directional function, so that the electronic apparatus 100 can directionally deliver sound to a designated location without affecting the surrounding environment.
As described above, the protective sheath can provide mounting locations for the ultrasonic directional sound device 300, that is, the protective sheath has more locations available for positioning the ultrasonic directional sound device 300, for example, the sides of the body portion 200. Optionally, the body portion 200 may be provided with the extension portion 220, the extension portion 220 is located at one side of the accommodating groove 230, and the ultrasonic directional sound emitting device 300 may be disposed at the extension portion 220, so as to avoid the side edge of the body portion 200 from being provided with an installation space for installing the ultrasonic directional sound emitting device 300, thereby preventing the side edge of the body portion 200 from being lower in strength due to the provision of the installation space, preventing the body portion 200 from being easier to deform or damage, and avoiding the protective sleeve from being incapable of better protecting the electronic device 100 from being knocked, and further improving the strength of the body portion 200. Meanwhile, since the electronic device 100 is currently developed in the direction of being light and thin, the thickness of the electronic device 100 is smaller, such that the side of the body 200 is narrower, and the difficulty of arranging the ultrasonic directional sound emitting device 300 on the side of the body 200 is greater, so that the ultrasonic directional sound emitting device 300 is arranged on the extension 220 to avoid such problems.
Further, the number of the extending portions 220 may be plural, and the plural extending portions 220 are disposed on different sides of the accommodating groove 230, for example, in the case that the number of the extending portions 220 is two, the extending portions 220 may be disposed on two opposite sides of the accommodating groove 230, or of course, may be disposed on two adjacent sides; in the case that the number of the extension parts 220 is three, the extension parts 220 may be disposed at any three sides of the circumference of the receiving groove 230; in the case that the number of the extension parts 220 is four, the extension parts 220 may be disposed at any four sides of the circumference of the receiving groove 230, which is not limited in the embodiment of the present invention.
In this scheme, a plurality of extension 220 can make and set up more ultrasonic wave directional sound emitting device 300 on this protective sheath, and more ultrasonic wave directional sound emitting device 300 can improve the performance of this protective sheath sound production certainly, and the directionality of the ultrasonic wave that more ultrasonic wave directional sound emitting device 300 sent is stronger. Meanwhile, in the case that the extension parts 220 are simultaneously provided at different sides of the receiving groove 230, when the user performs a conversation, enjoys songs, or enjoys video works, the electronic device 100 makes a stronger stereoscopic sense of sound through the extension parts 220 at different sides of the receiving groove 230, so that the user's experience is better.
Specifically, the plurality of ultrasonic directional sounding devices 300 can be distributed in sounding arrays, so that the plurality of ultrasonic directional sounding devices 300 can be regularly distributed on the protective sleeve, the situation that the plurality of ultrasonic directional sounding devices 300 are distributed in a scattered manner to cause the appearance of the protective sleeve to be attractive is avoided, and the plurality of ultrasonic directional sounding devices 300 distributed in arrays can also enable the directivity of ultrasonic waves emitted by the ultrasonic directional sounding devices to be stronger to a certain extent.
Further, the number of the sounding arrays may be plural, the plural sounding arrays may include at least one of square arrays, circular arrays and triangular arrays, and the plural sounding arrays may be disposed on the same side of the body portion 200. The radiating area of sound emitted by the sound emitting array is large, so that the situation that the user cannot hear the sound when the position between the sound emitting array and the electronic device 100 changes slightly can be avoided, and the use of the electronic device is convenient. Of course, the plurality of sounding arrays may be disposed on different sides of the body portion 200, and the space or the position of the different sides of the body portion 200 may be fully utilized, so that the sounding arrays may be disposed on the body portion 200 or the extension portion 220 more compactly and reasonably. Illustratively, the number of the sounding arrays is 4, the 4 sounding arrays are square arrays (of course, the 4 sounding arrays may also be triangular arrays), and the 4 sounding arrays are respectively located at four vertex angles on the same side of the body portion 200. In another embodiment, the plurality of sound emitting arrays may be circular arrays, and the plurality of circular arrays may be arranged along the same square at a certain interval, or the plurality of circular arrays may be arranged according to a certain pattern rule. For example, in the case where the sounding arrays are circular arrays and the number of sounding arrays is 6, the 6 circular arrays may be located on a preset radius circle centered on the center of the body portion 200, and the 6 circular arrays are equally spaced apart at preset intervals along the circumferential direction of the circle; or 6 circular arrays may be located at the same side of the body portion 200, and 6 circular arrays are located at six vertices of an equilateral hexagon, respectively.
Alternatively, the ultrasonic directional sound emitting device 300 may also be disposed on a side of the body portion 200 facing away from the accommodating groove 230, that is, the ultrasonic directional sound emitting device 300 is disposed on the back surface of the body portion 200, and since the area of the back surface of the body portion 200 is larger, a plurality of ultrasonic directional sound emitting devices 300 may be disposed on the back surface of the body portion 200, and the arrangement is convenient. When the user uses the device, the back face of the body 200 can be oriented towards the sound object to be received by adjusting the back face of the body 200, so that the sound is directionally transmitted to the sound object to be received, and the effect of transmitting private sound between the user and the sound object to be received is achieved. Further, the plurality of ultrasonic directional sound emitting devices 300 may be distributed in an array on a side of the body portion 200 facing away from the receiving groove 230.
When the user uses the electronic device 100 alone, it is necessary that sound be directionally propagated to the side where the user is located. Based on this, in an alternative embodiment, in the case where the electronic apparatus 100 is disposed on the body portion 200, the sound emitting direction of the ultrasonic directional sound emitting device 300 is the same as the orientation of the display screen 110 of the electronic apparatus 100, that is, the ultrasonic directional sound emitting device 300 may also be disposed on the front surface of the body portion 200. In this case, the sound can be transmitted to the user side, so that when the user uses the electronic device 100 alone, the user can not only watch the content displayed on the display screen 110, but also hear the sound, thereby improving the usability of the protective cover and improving the user experience.
Further, the ultrasonic directional sound emitting device 300 is rotatably disposed on the body portion 200, so that the protective sleeve can flexibly adjust the sound emitting direction of the ultrasonic directional sound emitting device 300 according to the specific position of the receiving object, so that the sound emitting direction of the ultrasonic directional sound emitting device 300 faces the receiving object, sound emitted by the ultrasonic directional sound emitting device 300 can be directionally transmitted to the position of the receiving object, further, the sound emitted by the protective sleeve can flexibly adjust the transmitting direction, and the situation that the sound cannot flexibly adjust the transmitting direction due to the fact that the position between the receiving object and the protective sleeve changes at any time is prevented, so that a user can use the device conveniently, and further, the situation that the user cannot hear the sound emitted by the protective sleeve is avoided.
As described above, the ultrasonic directional sound emitting device 300 is electrically connected with the electronic apparatus 100 through the electrical connection portion 210. Specifically, the electrical connection part 210 may include an electrical connection plug, which is plugged into the electrical connection port 120 of the electronic device 100 in a state that the electronic device 100 is disposed in the receiving groove 230, so that the electronic device 100 is electrically connected to the ultrasonic directional sound emitting device 300. The manner of electrical connection is reliable, and the electronic device 100 is generally provided with the electrical connection port 120, so that the manner can facilitate electrical connection between the electrical connection portion 210 and the electronic device 100, and avoid that the electronic device 100 needs to be arranged on an electrical connection device matched with the electrical connection portion 210, which results in complex structure and high cost of the electronic device 100.
Alternatively, the electrical connection part 210 may include a first coil electrically connected with a second coil of the electronic device 100 in case the electronic device 100 is disposed in the receiving groove 230. The electronic device 100 is electrically connected with the ultrasonic directional sound emitting device 300 through the electrical connection between the first coil and the second coil, and the electrical connection mode is through electromagnetic wireless connection, so that a bulge or an opening or the like connected with the electronic device is not required to be arranged on the protective sleeve, and the integrity of the protective sleeve is higher. Specifically, the electronic device 100 may supply power to the protective case through the first coil and the second coil, and the protective case may also supply power to the electronic device 100 through the first coil and the second coil, which is not limited in the embodiment of the present invention.
In a specific use process of the user, the user can select the electronic device 100 with the larger display screen 110 to display the content to be watched, then wirelessly connect (e.g. bluetooth) the electronic device 100 (e.g. a computer) with another electronic device 100 (e.g. a mobile phone), the other electronic device 100 is arranged on the protective sleeve and electrically connected with the protective sleeve, and the other electronic device 100 is used for playing the sound, that is, the other electronic device 100 plays a role of a wireless sound box, so that the user can watch the content displayed on the large screen and hear the stereo sound, and the experience of the user is high.
In an alternative embodiment, the protective case may further include a battery module, where the battery module may be disposed on the body portion 200 and electrically connected to the ultrasonic directional sound emitting device 300, and the electrical connection portion 210 may include a communication module, where the ultrasonic directional sound emitting device 300 may be communicatively connected to the electronic device 100 through the communication module, so that the electronic device transmits the sound signal to the protective case. Specifically, the communication module may be a wired communication module, and further, the communication module may be a wireless communication module (e.g., a radio frequency module, a bluetooth module, etc.). In this embodiment, the electronic device 100 can be wirelessly connected to the protective case, and even if the electronic device 100 is not provided to the protective case, the electronic device 100 can transmit sound through the protective case.
