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.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application are capable of operation in sequences other than those illustrated or described herein, and that the terms "first," "second," etc. are generally used in a generic sense and do not limit the number of terms, e.g., a first term can be one or more than one. 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 electronic device and the sound generating method provided by 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, fig. 1 is a schematic structural diagram of an electronic device provided in an embodiment of the present application, and as shown in fig. 1, the electronic device includes: the ultrasonic vibration device comprises a shell 10, a display screen 20, a signal processing module (not shown in the figure) and N ultrasonic vibrators 30, wherein the shell 10 is provided with a containing groove and M sound outlet holes 11, the display screen 20 is arranged in the containing groove and forms a containing cavity with the containing groove, the signal processing module and the N ultrasonic vibrators 30 are both positioned in the containing cavity, the signal processing module is respectively and electrically connected with the N ultrasonic vibrators 30, each ultrasonic vibrator 30 is respectively communicated with at least one sound outlet hole 11 through a sound guide channel, M is more than or equal to N is more than or equal to 2, and M, N is an integer;

the signal processing module is configured to modulate a first audio signal into a first modulation signal, and send the first modulation signal to P target ultrasonic vibrators of the N ultrasonic vibrators 30, so that each target ultrasonic vibrator sends an ultrasonic signal, and the P ultrasonic signals are superimposed at a target position to form a target audio corresponding to the first audio signal.

The ultrasonic vibrators 30 in the embodiment of the present application may be referred to as sound generating devices, the sound outlet holes may also be referred to as sound outlet channels, and a power amplifier may be further disposed between the signal processing module and each of the ultrasonic vibrators 30.

The working principle of the embodiment of the application can be referred to as the following expression:

the signal processing module can modulate the first audio signal into a first modulation signal and send the first modulation signal to the P target ultrasonic vibrators, the P target ultrasonic vibrators can send ultrasonic signals, the ultrasonic signals can be mutually interfered and superposed when being propagated in the air, and target audio corresponding to the first audio signal is formed at a target position. That is, the target audio cannot be received at a position other than the target position, so that as long as the user (i.e., the user using the electronic device) is located at the target position and the other user is not located at the target position, it is ensured that the other user cannot receive the target audio, thereby improving privacy when the electronic device plays the first audio signal.

It should be noted that, as an alternative implementation, the first modulation signal may be an ultrasonic signal, that is, the signal processing module may modulate the first audio signal into the ultrasonic signal, and the target ultrasonic vibrator may send the ultrasonic signal; as another alternative embodiment, the target ultrasonic vibrator may emit the first modulation signal in the form of an ultrasonic signal to the external environment.

For example: referring to fig. 2, the first audio signal may be f0, and the signal processing module may modulate the first audio signal into a plurality of first modulation signals (e.g. f1 and f2), and the first modulation signals f1 and f2 may pass through the corresponding sound emitting device (i.e. ultrasonic vibrator 30) and sound emitting channel (i.e. sound leading channel) in sequence, ultrasonic signals are formed to propagate in the air, and the ultrasonic signals can be subjected to interference superposition in the air, then obtaining at least one of signals f1+ f2, f1-f2, f2-f1 and the like, the superimposed signals f1+ f2, f1 and f2 are all in an ultrasonic frequency band, and the superimposed signals f1-f2 or f2-f1 may form a superposition at a target position after a self-demodulation process of air, so as to form target audio corresponding to the first audio signal (i.e., the playing content may be matched with the content of the first audio signal f 0). Therefore, the target audio has the advantages of high directivity, smaller side lobe and the like, and the privacy can be ensured to be better.

The target audio can be understood as: the main lobe of the sound pressure of the target audio has a certain pointing angle, which may also be understood as pointing to the target location.

It should be noted that the process of interference superposition and self-demodulation of the plurality of first modulation signals in the air may be collectively referred to as a nonlinear propagation effect.

In addition, the phases of the ultrasonic signals emitted by any two target ultrasonic vibrators in the P target ultrasonic vibrators may be the same or different. For example: when the target position is a position in a direction perpendicular to the center position of the display screen 20 of the electronic device, the phases of the ultrasonic signals emitted from any two target ultrasonic vibrators may be the same; when the target position is other positions, the phases of the ultrasonic signals emitted by some of the P target ultrasonic vibrators may be different.

It should be noted that the signal processing module may include a control unit, and the control unit may control the phase of the first modulation signal sent to each target ultrasonic vibrator, so as to adjust the superposition forming position of the target audio.

Meanwhile, the target position can be determined according to the specific position of the face image of the user of the electronic equipment, and then the phase of the ultrasonic signal sent by each target ultrasonic vibrator is determined according to the target position and the specific position of each target ultrasonic vibrator, so that the target audio corresponding to the first audio signal can be obtained by interference superposition of the ultrasonic signals sent by the plurality of target ultrasonic vibrators.

The manner of detecting the specific position of the face image of the user is not specifically limited herein, for example: the detection method can be infrared detection, ultrasonic detection or the like.

In addition, since the ultrasonic signal is transmitted to the external environment by the vibration of the ultrasonic vibrator 30, other noise is not generated by the vibration of the ultrasonic vibrator 30, and thus the interference of the noise to the user can be reduced.

The distribution manner of the N ultrasonic vibrators 30 is not limited herein, and as an alternative embodiment, the N ultrasonic vibrators 30 may be randomly distributed.

As another alternative, the N ultrasonic vibrators 30 are distributed in an array. Thus, compared with the mode that the N ultrasonic vibrators 30 are intensively distributed at a certain position, the distribution of the N ultrasonic vibrators 30 can be more uniform, and the target audio can be better formed in a superposed mode at the target position.

Of course, the number of the ultrasonic vibrators 30 is not limited herein, for example: the number of ultrasonic vibrators 30 (i.e., the value of N) may be an even number, such as 4, 6, or 8.

In addition, as an alternative embodiment, N ultrasonic vibrators 30 may be disposed on the housing 10 of the electronic device, for example: the housing 10 is provided with a plurality of receiving holes, and an ultrasonic vibrator 30 is embedded in each receiving hole.

Certainly, as another optional implementation manner, referring to fig. 1, the electronic device includes a housing 10, the housing 10 is provided with a containing groove and M sound outlet holes 11, the display screen 20 is disposed in the containing groove and forms a containing cavity with the containing groove, the signal processing module and the N ultrasonic vibrators 30 are both located in the containing cavity, the signal processing module is electrically connected to the N ultrasonic vibrators 30, each ultrasonic vibrator 30 is communicated with at least one sound outlet hole 11 through a sound guide channel, M is greater than or equal to N and is greater than or equal to 2, and M, N is an integer.

Like this, owing to be provided with M sound outlet 11, then ultrasonic vibrator 30 can be through sound outlet 11 sound, need not to set up ultrasonic vibrator 30 on casing 10 to can strengthen the protective effect to ultrasonic vibrator 30, simultaneously, set up ultrasonic vibrator 30 in the holding intracavity, can make electronic equipment more pleasing to the eye, waterproof dustproof performance is better.

The ultrasonic vibrators 30 and the sound outlet holes 11 can be arranged in a one-to-one opposite mode, namely the sound guide channels can be respectively perpendicular to the ultrasonic vibrators 30 and the sound outlet holes 11, and the distance between the sound guide channels is shortest, so that the transmission loss of signals in the sound guide channels can be reduced; of course, the ultrasonic vibrator 30 and the sound outlet 11 may also be arranged in a staggered manner, that is, the sound guide channel may form a certain included angle with the ultrasonic vibrator 30 and the sound outlet 11, so that the arrangement position of the ultrasonic vibrator 30 may be more flexible, that is, the ultrasonic vibrator is not limited to the position opposite to the sound outlet 11.

As an alternative embodiment, referring to fig. 1, the M sound holes 11 are located between the edge of the display screen 20 and the inner wall of the accommodating groove.

Like this, because M sound outlet 11 is located between the edge of display screen 20 and the inner wall of storage tank, can reduce the influence of sound outlet 11 to the display effect of display screen 20, can guarantee the integrality of the structure of display screen 20, increase electronic equipment's screen accounts for the ratio.

The sound outlet 11 may be a part of an assembly gap between the edge of the display screen 20 and the inner wall of the accommodating groove, and the other part of the assembly gap, which is not the sound outlet 11, may be filled with an adhesive layer, so as to enhance the connection strength between the display screen 20 and the housing 10, and enhance the fixing effect on the display screen 20.

Optionally, referring to fig. 3, an embodiment of the present application further provides a sound generating method of an electronic device, where the method may be applied to the electronic device in the foregoing embodiment, that is, the electronic device may include: the ultrasonic vibration testing method comprises a shell 10, a display screen 20, a signal processing module and N ultrasonic vibrators 30, wherein a containing groove and M sound outlet holes 11 are formed in the shell 10, the display screen 20 is arranged in the containing groove and forms a containing cavity with the containing groove, the signal processing module and the N ultrasonic vibrators 30 are located in the containing cavity, the signal processing module is electrically connected with the N ultrasonic vibrators 30 respectively, each ultrasonic vibrator 30 is communicated with at least one sound outlet hole 11 through a sound guide channel, M is not less than N and not less than 2, M, N is an integer, and the ultrasonic vibration testing method comprises the following steps:

step 301, determining a target position of the target object.

When the target object is a user of the electronic equipment, the target audio is only generated at the target position, so that the privacy of target audio playing can be enhanced, and the influence on other users is reduced; of course, when the target object is other object, for example: animals such as rabbits can drive animals because the target audio is only formed at the target position.

Step 302, determining P target ultrasonic vibrators from the N ultrasonic vibrators according to the first audio signal and the target position, and obtaining a first modulation signal.

The process of obtaining the first modulation signal may refer to the related expression in the above embodiment, that is, the first modulation signal may be obtained by modulating the signal processing module, and details are not repeated herein.

The P target ultrasonic vibrators are determined according to the first audio signal and the target position, and then the phase of the ultrasonic signal sent by each target ultrasonic vibrator can be determined, so that the accuracy of forming the target audio by overlapping at the target position is high.

Step 303, controlling the signal processing module to send the first modulation signal to the P target ultrasonic vibrators of the electronic device, so that each target ultrasonic vibrator sends an ultrasonic signal, and the P ultrasonic signals are superposed at the target position to form a target audio corresponding to the first audio signal; wherein N is more than or equal to P and more than or equal to 2, and P is an integer.

For a specific generation principle of the target audio, reference may be made to corresponding expressions in the above embodiments, and details are not described herein again.

The first audio signal may be an audio signal played by the electronic device, or may also be an audio signal included in a played video, which is not limited herein. Of course, the first audio signal may be an audio signal stored locally in the electronic device, or may also be an audio signal received or downloaded from a server, and is not limited herein.

Optionally, the electronic device further includes a camera and/or a distance sensor, and before the controlling the signal processing module to send the first modulation signal to the P target ultrasonic vibrators of the electronic device, the method further includes:

controlling the camera to collect a target image containing the target object, and determining the target position according to the target image; and/or the presence of a gas in the gas,

and acquiring a target distance between the target object and the electronic equipment through the distance sensor, and determining the target position according to the target distance.

The working principle of determining the target position according to the camera can be referred to as the following expression: the camera may be a TOF camera, such that the target position may be determined from depth information of the target object included in the target image.

The working principle of determining the position of the target by the distance sensor can be seen in the following expression: the distance sensor may be an infrared sensor, and the infrared sensor may determine the target position of the target object by the emitted infrared light and the received reflected infrared light that is reflected back into the electronic device via the target object.

In this way, the accuracy of the target location determination may be improved by the camera and/or the distance sensor.

In addition, the target position is determined by the target image collected by the camera, which can be expressed as follows: if the target object may be a user, the camera acquires a face image of the user, and then a process of how to determine the phase of the first modulation signal (i.e., the modulation signal in fig. 5) may refer to steps 501 to 506 in fig. 5, which is not described herein again. Therefore, the pointing angle (target position) is adjusted in real time according to the position of the face image, so that the purpose that the pointing angle follows the face can be achieved, and the pointing angle always points to the face direction of the user.

Optionally, the first modulation signal comprises P sub-signals, each sub-signal corresponding to one target ultrasonic vibrator, and the phase and intensity of each sub-signal are related to the position of the corresponding target ultrasonic vibrator. Therefore, through the interference superposition of the P sub-signals, the accuracy of forming the target audio by superposition at the target position can be further improved, and the privacy of target audio playing is further improved.

Optionally, before the controlling the signal processing module to send the first modulation signal to the P target ultrasonic vibrators of the electronic device, the method further includes:

controlling the N ultrasonic vibrators to send second modulation signals;

receiving a reflected signal obtained by reflecting the second modulation signal by the target object;

and determining target operation according to the reflection signal.

The target operation is not specifically limited herein, and for example: the target operation may be to control a display screen of the electronic device to be turned on or off, and of course, the target operation may also be to adjust the volume of the electronic device.

As an alternative embodiment, the reflected signal is a signal continuously acquired in a time period. Therefore, the accuracy of the reflected signal acquisition result can be ensured, and meanwhile, the electronic equipment can be prevented from being always in the acquisition state of the reflected signal, so that the power consumption of the electronic equipment can be reduced.

Additionally, the target operation may also be to determine a sound emission pattern of the electronic device. For example: as an optional implementation, the determining the target position of the target object includes:

and determining the target position of the target object under the condition that the target sound production mode is the first sound production mode.

As another optional implementation, after determining the target position of the target object, the method further includes: and under the condition that the target sound production mode is a second sound production mode, controlling at least part of the M sound outlets to play a first audio signal.

Therefore, the electronic equipment can be determined to be in the first sound-emitting mode or the second sound-emitting mode through the reflected signal of the second modulation signal, and the determination mode of the sound-emitting mode of the electronic equipment is more intelligent.

The second modulation signal may also be in an ultrasonic frequency band, so that interference to a user is small, and the second modulation signal and the first modulation signal may be signals of different frequency bands, and the second modulation signal and the first modulation signal do not interfere with each other.

The sound production modes of the electronic equipment are different, and then the sound production modes of the electronic equipment are different. When other users exist in the external environment, the problem that privacy is poor exists at the moment, the electronic equipment needs to be controlled to be in the first sound emitting mode, namely, the signal processing module is controlled to send the first modulation signals to the P target ultrasonic vibrators, so that target audio is formed at the target position.

In addition, as an optional implementation manner, the determining a target operation according to the reflection signal includes:

determining a target action of the target object according to the reflection signal;

and determining target operation according to the target action.

The specific type of the target action is not limited herein, for example: when the target object is a user, the target motion may be a gesture motion, a limb motion, a head motion, or the like of the user.

Therefore, the target operation can be determined according to the target action, so that the control of the electronic equipment is more intelligent and flexible.

Of course, in the case where the target operation is to determine the sound emission mode of the electronic device, the sound emission mode of the electronic device may be determined according to the target motion, and as can be seen from the above, the sound emission mode of the electronic device may include the first sound emission mode and the second sound emission mode.

Specifically, how to detect whether the user wants to control the electronic device to be in the first sound emitting mode or the second sound emitting mode may be to emit a second modulation signal, where the second modulation signal is emitted back to the electronic device after encountering the user, and the electronic device may determine the sound emitting mode of the electronic device according to the detected reflection signal, which may be specifically referred to as corresponding statements in the foregoing embodiments.

For example: as an alternative embodiment, the determining a target operation according to the reflected signal includes:

determining a target gesture of a user according to the reflection signal;

and determining that the electronic equipment is in a first sound production mode or a second sound production mode according to the target gesture.

The reflected signals can return to the electronic device through the palm of the user, and different reflected signals indicate that target gestures of the user are different, so that whether the electronic device is in the first sound production mode or the second sound production mode can be determined according to the target gestures.

It should be noted that the target gestures and the sound production modes are in one-to-one correspondence, and the correspondence may be stored in the electronic device body, or of course, may be obtained by the server.

Therefore, the electronic equipment can be controlled to be in the first sound production mode or the second sound production mode through different gestures, and therefore the sound production mode can be determined more conveniently and accurately.

It should be noted that, referring to fig. 1, at least one sound collection component 40 (also referred to as a microphone) and an analog-to-digital converter may also be disposed in the electronic device, the sound collection component 40 is connected to a processor of the electronic device through the analog-to-digital converter, and the receiving of the reflected signal of the second modulation signal may be implemented by the sound collection component 40, and then after the reflected signal is converted by the analog-to-digital converter, the target gesture is recognized in the processor. Of course, the sound collection unit 40 and the analog-to-digital converter may be connected through a power amplifier.

For example: the process of transmitting the second modulation signal and receiving the corresponding reflection signal can be referred to fig. 4, and is not described herein again.

In the embodiment of the present application, through steps 301 to 303, each target ultrasonic vibrator sends an ultrasonic signal, and P ultrasonic signals are superimposed at a target position to form a target audio corresponding to the first audio signal, while other positions do not form the target audio, that is, other positions cannot receive the target audio, so that a privacy effect when playing audio or video is enhanced.
