The method for outputting the voice and the terminal device provided by the embodiment of the invention can be applied to the process that the terminal device outputs the voice by adopting the screen sounding technology.

Specifically, in the embodiment of the present invention, at least two sound units are disposed in the terminal device. Wherein, because terminal equipment can control every sound producing unit in its two at least sound producing units respectively, consequently terminal equipment can be according to the demand respectively through one or more sound producing unit output pronunciation in two at least sound producing units, if through the sound producing unit output pronunciation that is nearest among two at least sound producing units apart from the user's ear, and other sound producing unit output pronunciation outside this sound producing unit of not going out. Therefore, the problem of poor privacy in the process of outputting voice by the terminal equipment can be solved.

It should be noted that, in the method for outputting a voice provided in the embodiment of the present invention, the execution main body may be a terminal device, or a Central Processing Unit (CPU) of the terminal device, or a control module in the terminal device for executing the method for outputting a voice. In the embodiment of the present invention, a method for a terminal device to execute a voice output is taken as an example, and the method for outputting a voice provided in the embodiment of the present invention is described.

The terminal device in the embodiment of the present invention may be a terminal device having an operating system. The operating system may be an Android (Android) operating system, an ios operating system, or other possible operating systems, and embodiments of the present invention are not limited in particular.

The following describes a software environment applied by the method for outputting speech provided by the embodiment of the present invention, taking an android operating system as an example.

Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.

The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application. For example, applications such as a system setup application, a system chat application, and a system camera application. And the third-party setting application, the third-party camera application, the third-party chatting application and other application programs.

The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the method for outputting a voice provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the method for outputting a voice may run based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can implement the method for outputting the voice provided by the embodiment of the invention by running the software program in the android operating system.

The method for outputting speech provided by the embodiment of the present invention is described in detail below with reference to the flowchart of the method for outputting speech shown in fig. 2. Wherein, although a logical order of methods of outputting speech provided by embodiments of the present invention is shown in a method flow diagram, in some cases, the steps shown or described may be performed in an order different than here. For example, the method of outputting voice shown in fig. 2 may include S201 and S202:

s201, the terminal device determines a first sound generating unit from the at least two sound generating units, wherein the first sound generating unit is the sound generating unit which is closest to the ears of the user in the at least two sound generating units.

The voice output mode of the terminal device may include an earphone mode and a speaker mode.

It can be understood that, in a scenario where the voice output mode of the terminal device is the earpiece mode, the user generally needs that the voice output by the terminal device is not heard by other users, that is, the privacy requirement on the process of outputting the voice by the terminal device is high.

Alternatively, the terminal device may determine the first sound emitting unit from the at least two sound emitting units in a scenario where the voice output mode of the terminal device is the earpiece mode.

Optionally, at least two sound units in the terminal device may be distributed below a screen of the terminal device, or below a bezel of the terminal device. Of course, the at least two sound units may also be disposed at other positions in the terminal device, which is not described again in this embodiment of the present invention.

It should be noted that the terminal device may determine one or more first sound emitting units from the at least two sound emitting units, where the one or more first sound emitting units are located at the same distance from the user's ear. That is, the number of sound emission units closest to the ears of the user among the at least two sound emission units may be one or more.

It is understood that the number of sound units closest to the ears of the user among the at least two sound units in the terminal device is usually one, i.e. the number of first sound units is one.

Optionally, in this embodiment of the present invention, the terminal device may execute the S201 once every certain time (e.g., 1 minute), or the terminal device may execute the S201 when the terminal device is to output a voice.

S202, the terminal device outputs voice through the first voice unit.

Optionally, when the terminal device determines that the obtained number of the first sound emitting units is multiple, the terminal device may output the voice through the multiple first sound emitting units at the same time. Alternatively, the terminal device may output a voice through any one of the plurality of first sound emitting units.

It can be understood that, in the embodiment of the present invention, each of the at least two sound emitting units included in the terminal device corresponds to a different area in the terminal device. That is, one sound emitting unit can make the area where the sound emitting unit is located in the terminal device emit sound to output voice, and the other areas except the area in the terminal device do not output voice.

It should be noted that the method for outputting voice provided by the embodiment of the present invention is applied to a terminal device, where at least two sounding units are provided in the terminal device. Specifically, the terminal device may determine a first sound generating unit from the at least two sound generating units, where the first sound generating unit is a sound generating unit closest to the ear of the user from the at least two sound generating units; and outputs the voice through the first sound-emitting unit. Based on the scheme, the terminal equipment controls the first sound emitting unit closest to the ear of the user to output the voice, so that the terminal equipment mainly outputs the voice through sound emission of the area where the first sound emitting unit is located in the terminal equipment, namely, the area except the area in the terminal equipment can not emit the sound, and other users are not easy to hear the voice output by the terminal equipment. Therefore, the privacy of the voice output process of the terminal equipment can be improved.

In a possible implementation manner, in the embodiment of the present invention, at least two sound emitting units may be disposed below a screen of the terminal device.

It should be noted that each of the at least two sound units below the screen of the terminal device corresponds to an area in the screen, and the area corresponding to each sound unit is different. Wherein, a sound production unit vibration can drive the regional vibration sound production in the screen that this sound production unit corresponds.

Optionally, at least two sound generating units arranged in the terminal device are uniformly distributed below a screen of the terminal device. Therefore, the terminal device can respectively control any sound generating unit of the at least two sound generating units to vibrate and generate sound by driving the area in the screen corresponding to the sound generating unit to vibrate.

Optionally, each of the at least two sound units in the terminal device may be connected to the screen, for example, each sound unit may be pasted below the screen of the terminal device.

Exemplarily, as shown in fig. 3, a schematic diagram of a position distribution of a sound generating unit provided in an embodiment of the present invention is shown. Fig. 3 (a) shows an inner surface 301 of the screen 30, and the inner surface 301 is a surface of the screen 30 to which the sound emission unit 302, the sound emission unit 303, the sound emission unit 304, and the sound emission unit 305 are adhered. While (b) in fig. 3 shows the outer surface 306 of the screen 30, the shaded area on the screen 30 shown in (b) in fig. 3 may be an area on the screen 30 where the user's ear is mapped, which falls within an area corresponding to one sound emitting unit. I.e. the sound generating unit is the sound generating unit closest to the user's ear.

In addition, it should be noted that the outer surface 306 of the screen 30 in the terminal device shown in fig. 3 is disposed opposite to the inner surface 301, and the outer surface 306 is in contact with air and is a surface of the screen 30 closer to the ear of the user. Specifically, the sound generating unit of the terminal device vibrates to drive the screen 30 to vibrate and generate the voice, which is output through the inner surface 301 and then transmitted to the ear of the user through the outer surface 306.

Specifically, the screen 30 shown in fig. 3 (a) and 3 (b) includes a region P1, a region P2, a region P3, and a region P4. The sound emitting unit 302 corresponds to the area P1, that is, the terminal device controls the sound emitting unit 302 to vibrate, and can drive the area P1 in the screen 30 to vibrate and emit sound; the sound emitting unit 303 corresponds to the area P2, that is, the terminal device controls the sound emitting unit 303 to vibrate, and can drive the area P2 in the screen 30 to vibrate and emit sound; the sound emitting unit 304 corresponds to the area P3, that is, the terminal device controls the sound emitting unit 304 to vibrate, and can drive the area P3 in the screen 30 to vibrate and emit sound; and the sound emitting unit 305 corresponds to the area P4, that is, the terminal device controls the sound emitting unit 305 to vibrate, and can drive the area P4 in the screen 30 to vibrate and emit sound.

For example, in the embodiment of the present invention, the at least two sound generating units in the terminal device may include the sound generating unit 302, the sound generating unit 303, the sound generating unit 304, and the sound generating unit 305 described above.

Specifically, in the method for outputting a speech according to the embodiment of the present invention, the step S202 may be implemented by the step S202':

s202', the terminal equipment controls the first sound-emitting unit to vibrate so as to drive the screen to vibrate and emit sound, and then voice is output.

Illustratively, in conjunction with each sound emitting unit shown in fig. 3 (a), the first sound emitting unit in the embodiment of the present invention may be the sound emitting unit 302 shown in fig. 3 (a). That is, the terminal device may control the sound emission unit 302 to vibrate to drive the screen 30 to vibrate for sound emission, specifically, to drive the area P1 in the screen 30 to vibrate for sound emission, and output voice.

It is understood that, in the case that the voice output mode of the terminal device is an earphone mode, when the ear of the user is close to the screen, the voice output by vibrating the sound production in the area of the user's ear mapped on the screen can be heard by the user. That is, the first sound generating unit closest to the ear of the user among the at least two sound generating units in the terminal device vibrates to drive the screen corresponding to the first sound generating unit to vibrate and generate the output voice, so that the requirement of the user for listening to the voice can be met.

Optionally, in an embodiment of the present invention, each of the at least two sound units is made of a piezoelectric material.

The piezoelectric material is a material capable of realizing mutual conversion between mechanical vibration and alternating current.

Specifically, the sound generating unit in the embodiment of the present invention can convert a voice signal (i.e., alternating current) into mechanical vibration, and the screen is driven to vibrate by the vibration of the sound generating unit, i.e., the screen is driven to vibrate and generate sound to output voice. The terminal device controls the sound production unit to drive the screen to vibrate and produce the voice, and the voice is output and changes along with the change of the voice signal received by the sound production unit, for example, the voice changes along with the change of the frequency of the voice signal.

Optionally, in the embodiment of the present invention, one sound generating unit may be an exciter or a driver, so that the terminal device controls the sound generating unit to drive the screen to vibrate and generate sound to output voice.

Optionally, in the embodiment of the present invention, when the voice output mode of the terminal device is the speaker mode, the terminal device may control at least two sound generating units to vibrate, so as to drive the screen to vibrate and generate sound, and output stereo surround voice. The phase of the voice signal for controlling the vibration of each of the at least two sound units may be set according to actual requirements, and the embodiment of the present invention is not particularly limited.

It will be appreciated that in a scenario in which the speech output mode of the terminal device is in handset mode, the user will typically bring the screen of the terminal device close to the ear.

It should be noted that, in the method for outputting voice provided in the embodiment of the present invention, because the terminal device controls the first sound emitting unit closest to the ear of the user to vibrate to drive the screen to vibrate and emit sound so as to output voice, the terminal device mainly vibrates and emits sound by the area in the screen corresponding to the first sound emitting unit, that is, the area except the area in the screen may not vibrate and emit sound, that is, other users cannot easily hear the voice output by the terminal device. Therefore, the privacy of the voice output process of the terminal equipment can be further improved.

In a possible implementation manner, in the method for outputting a voice provided by the embodiment of the present invention, the terminal device may determine the distance between the at least two sound units and the ear of the user by using an ultrasonic ranging method to determine the first sound unit. Specifically, the above S201 may include S201a, S201b, and S201 c. Exemplarily, as shown in fig. 4, a flow chart of another method for outputting speech according to an embodiment of the present invention is shown. As shown in fig. 4, S201 shown in fig. 2 may be replaced with S201a, S201b, and S201 c:

s201a, the terminal device obtains corresponding distance values for each of the at least two sound units, respectively, to obtain at least two distance values.

The distance value corresponding to each sound production unit is used for representing the distance between the sound production unit and the ear of the user.

In addition, it is understood that the terminal device may control the sound emitting unit to drive the screen to vibrate for sound emission and output the voice, and may control the sound emitting unit to drive the screen to vibrate for ultrasonic wave output.

The sound production unit provided by the embodiment of the invention can convert the ultrasonic signals into mechanical vibration so as to drive the screen to vibrate and output ultrasonic waves. And after the ultrasonic wave that terminal equipment passed through the sound production unit output met the barrier, the ultrasonic wave that is reflected back by the barrier reachs this screen, can make this screen vibration and drive the sound production unit vibration to make the sound production unit turn into the alternating current with mechanical vibration, realize that terminal equipment passes through the sound production unit promptly and receives the ultrasonic wave. When the terminal device controls the screen of the sound generating unit to drive the sound generating unit to generate sound and output ultrasonic waves, the signal received by the terminal device may be a signal with a fixed frequency, for example, the fixed frequency is greater than 20000 Hertz (HZ).

Specifically, sound generating unit (like first sound generating unit) among the terminal equipment vibrates to this terminal equipment can begin the timing when the drive screen vibrates and outputs the ultrasonic wave, and this terminal equipment can stop the timing when receiving the ultrasonic wave that the barrier (like user's ear) reflected back through this sound generating unit. The propagation speed of the ultrasonic wave in the air is 340m/S (meters per second), and according to the time (denoted as T) counted by the terminal device, the distance (denoted as S) between the screen of the terminal device (specifically, the sound generating unit in the screen area where the ultrasonic wave is emitted) and the ear of the user can be calculated, that is: and S is 340T/2.

To sum up, the terminal device can vibrate through controlling every sound producing unit in at least two sound producing units to drive the screen vibration and output the ultrasonic wave, thereby obtain the distance numerical value that a sound producing unit corresponds.

S201b, the terminal device determines a minimum first distance value from the at least two distance values.

For example, in connection with each sound emitting unit in the terminal device shown in fig. 3, the distance value corresponding to the sound emitting unit 302 may be recorded as distance value 1, the distance value corresponding to the sound emitting unit 303 may be recorded as distance value 2, the distance value corresponding to the sound emitting unit 304 may be recorded as distance value 3, and the distance value corresponding to the sound emitting unit 305 may be recorded as distance value 4.

For example, the at least two distance values may include a distance value of 1 to a distance value of 4, and the first distance value may be a distance value of 1.

S201c, the terminal device determines that the sound production unit corresponding to the first distance value is the first sound production unit.

Illustratively, the sound unit 302 corresponding to the distance value 1 is the first sound unit.

It should be noted that, in the method for outputting a voice provided by the embodiment of the present invention, because the terminal device can obtain, for each of the at least two sound units, a distance value corresponding to each sound unit, so that the terminal device can determine, according to one distance value, a distance from one sound unit to the ear of the user, and thus the terminal device can determine the first sound unit closest to the ear of the user in the at least two sound units. Therefore, the terminal device can control the first sound-emitting unit to vibrate to drive the screen to vibrate and emit sound so as to output voice.

In a possible implementation manner, in the method for outputting a voice according to the embodiment of the present invention, when the terminal device outputs a voice through the first sound emitting unit, other areas except for an area where the first sound emitting unit is located in the terminal device may also output a voice. Specifically, in order to further improve the privacy of the voice output by the terminal device, the method for outputting the voice provided by the embodiment of the present invention may further include, after the foregoing step 201, S203, and for example, after S202, may further include S203:

s203, the terminal device outputs a suppressed voice through each second sound generating unit of the at least one second sound generating unit respectively so as to output at least one suppressed voice, wherein the phase of each suppressed voice is opposite to the phase of the voice.

The at least one second sound generating unit is the other sound generating units except the first sound generating unit in the at least two sound generating units.

It is understood that, since the phase of the voice output by the first sound generating unit (i.e., the phase of the sound wave of the voice) and the phase of the suppressed voice output by one second sound generating unit (i.e., the phase of the sound wave of the suppressed voice) are opposite, the suppressed voice output by one second sound generating unit can suppress the voice output by the first sound generating unit.

Typically, the intensity of the suppressed speech output by one of the second sound units is less than the intensity of the speech output by the first sound unit.

It should be noted that, in the method for outputting a voice according to the embodiment of the present invention, after the terminal device outputs a voice through the first sound generating unit, the terminal device may further enable each of the at least two second sound generating units to output a suppressed voice; and the phase of one suppressed voice is opposite to the phase of the voice output by the first sound generating unit, so that when the terminal equipment outputs the voice through the area where the first sound generating unit is located, the voice is not output by the area except the area in the terminal equipment. Therefore, the privacy of the voice output process of the terminal equipment is further improved.

In a possible implementation manner, according to the method for outputting voice provided by the embodiment of the present invention, in the process that the terminal device controls the first unit to vibrate to drive the screen of the terminal device to vibrate and generate sound to output voice, the screen of the terminal device mainly vibrates through the area corresponding to the first sound generation unit, but other areas except the area in the screen may also vibrate slightly, that is, the other areas may also vibrate and generate sound to output voice. Therefore, in order to ensure privacy of the process of outputting the voice by the terminal device, the terminal device needs to suppress vibration sound emission in the other area.

Specifically, in the embodiment of the present invention, S202 may be replaced with S202a, and S203 may be replaced with S203 a. Exemplarily, as shown in fig. 5, a flow chart of another method for outputting speech according to an embodiment of the present invention is shown. With reference to fig. 2, S202 shown in fig. 2 may be replaced with S202a shown in fig. 5, and S203a is further included after S202 a:

s202a, the terminal device controls the first sound emitting unit to convert the received first voice signal into mechanical vibration, so as to drive a first area corresponding to the first sound emitting unit on the screen to vibrate and emit sound, and output voice from the first area.

For example, the first sound emitting unit may be the sound emitting unit 302 shown in fig. 3, and the first area may be the area P1 shown in fig. 3.

It is emphasized that the first speech signal (denoted as speech signal 1) is an electrical signal for the terminal device to generate speech (denoted as speech 1) to be output. Specifically, the terminal device may send a first voice signal to the first sound emitting unit through its CPU, so that the first sound emitting unit receives the first voice signal.

It can be understood that when the terminal device controls the first sound-emitting unit to vibrate to drive the first area of the screen to vibrate for sound emission, the vibration of the first area may drive other areas of the screen except the first area to vibrate slightly.

Optionally, the volume of the voice output by the terminal device mainly depends on the amplitude of the vibration of the first area in the screen, and the amplitude of the vibration of the first area depends on the strength of the first voice signal.

Optionally, after receiving an operation that the user triggers the terminal device to adjust the volume of the output voice, the terminal device may adjust the intensity of the first voice signal in response to the operation, so as to adjust the intensity of the first voice signal in the terminal device, and further adjust the volume of the voice output by the terminal device.

S203a, the terminal device controls each of the at least one second sound generating unit to convert the received second voice signal into mechanical vibration, so as to drive a second area corresponding to the one second sound generating unit on the screen to generate a vibration sound, and output a suppressed voice, and further output at least one suppressed voice.

Wherein the phase of the first voice signal is opposite to the phase of the second voice signal.

It should be noted that, in the embodiment of the present invention, when the screen of the terminal device vibrates and drives the sound generating unit to vibrate, the terminal device may control the sound generating unit to convert the mechanical vibration of the terminal device into a voice signal. Of course, the terminal device may also report the detected voice signal to a CPU in the terminal device. Subsequently, the terminal device may adjust the phase and/or intensity of the voice signal by the CPU, and transmit the adjusted voice signal to the sound emitting unit.

Specifically, in the embodiment of the present invention, the terminal device may detect noise in an environment, for example, the terminal device may control any one of the at least one second sound emitting unit to detect a voice over the second area in the screen corresponding to the second sound emitting unit. When the second area in the screen of the terminal device vibrates along with the voice (such as voice 1) output by the first area and drives the second sound generating unit corresponding to the second area to vibrate, the second sound generating unit can convert the mechanical vibration into a voice signal (recorded as voice signal 2). Of course, the terminal device may control the second sound generating unit to report the voice signal 2 to the CPU.

It can be understood that the speech signal 1 and the speech signal 2 are both speech signals corresponding to the speech 1, wherein the strength of the speech signal 1 is greater than that of the speech signal 2, and the phases of the speech signal 1 and the speech signal 2 are the same at the same time.

Optionally, after receiving the voice signal 2 reported by any second sound generating unit, the CPU in the terminal device may generate, in real time, a voice signal 3 (i.e., a second voice signal) having the same strength and an opposite phase to the voice signal 2. Subsequently, after the second sound production unit in the terminal device receives the voice signal 3 sent by the CPU, the voice signal 3 can be converted into mechanical vibration to drive the second area to produce sound through vibration. For example, the second sound emitting unit may be the generating unit 303 shown in fig. 3, and the second area may be the area P2 shown in fig. 3.

It can be understood that, because the phases of the voice signal 1 and the voice signal 3 at the same time are opposite, that is, the phases of the voice signal 2 and the voice signal 3 at the same time are opposite, the vibration direction of the first area of the screen in the terminal device vibrating and driving the second area to vibrate at the same time may be opposite to the vibration direction of the second area vibrating when the terminal device controls the second sound generating unit to vibrate and drive the second area to vibrate, and the vibration amplitudes of the two vibrations may be the same. When the directions of the two vibrations on the second area are opposite at the same time, the vibration of the second area can be suppressed; further, the vibration amplitude of the two vibrations is the same at this time, and the vibration of the second region can be eliminated.

It should be noted that, according to the method for outputting voice provided by the embodiment of the present invention, when the terminal device can output voice by controlling the first area in the screen to vibrate and emit voice, the terminal device can suppress or even eliminate the second area in the screen to vibrate and emit voice and output voice. Therefore, the privacy of the voice output process of the terminal equipment is further improved.

In one possible implementation, when a user listens to speech using the terminal device in the earpiece mode, the mapped area of the user's ear on the screen of the terminal device may change. Therefore, in order to ensure the privacy of the voice output process of the terminal device, the terminal device can detect the area mapped by the user's ear on the screen, namely the area corresponding to the vocalization list closest to the user's ear in real time, and output the voice through the area.

Specifically, the method for outputting speech provided in the embodiment of the present invention, after the above S202, may further include S204-S206:

s204, the terminal device respectively obtains corresponding distance values for each second sound production unit in the at least one second sound production unit to obtain at least one distance value.

The distance value is used for representing the distance between one sound production unit and the ear of the user, and the at least one second sound production unit is the other sound production unit except the first sound production unit in the at least two sound production units.

S205, the terminal equipment determines a minimum second distance value from at least one distance value.

And S206, under the condition that the second distance value is smaller than the first distance value, the terminal equipment outputs voice through the voice generating unit corresponding to the second distance value.

For example, the sound emitting unit corresponding to the second distance value may be the sound emitting unit 304 shown in (a) of fig. 3.

Similarly, the descriptions of S204 to S206 in the embodiments of the present invention may refer to the descriptions of S201a, S201b, and S201c in the above embodiments, and are not repeated herein.

It should be noted that, in the embodiment of the present invention, the terminal device may determine, in real time, a sound generating unit closest to an ear of the user in the terminal device, and may control the sound generating unit to vibrate to drive the screen to vibrate and generate sound to output voice. In this way, when a user listens to voice using the terminal device, even if the area of the user's ear mapped on the screen of the terminal device changes, the terminal device can control the sound production unit closest to the user's ear to produce sound by vibration. Therefore, the privacy of the voice output process of the terminal equipment can be improved, and meanwhile, the user can be ensured to hear the voice.

In a possible implementation manner, in the method for outputting a speech according to the embodiment of the present invention, the step S201 may be replaced by the step S207:

s207, under the condition that the terminal device is to output voice and the voice output mode of the terminal device is the earphone mode, the terminal device determines a first sound generating unit from at least two sound generating units.

The condition of the terminal device to output the voice comprises at least one of the following conditions 1 and 2:

condition 1: the terminal device and other terminal devices communicate by voice.

Optionally, the terminal device determines whether the condition 1 is satisfied, and may:

the terminal device responds to the voice call request. For example, the terminal device receives an input for answering the call triggered when the system call or the third-party network call is received.

Or the terminal equipment initiates a voice call request. For example, the terminal device initiates the input of a dial-out call triggered when a system call or a third-party network call is initiated.

Or the terminal equipment responds to the voice call request. For example, when the terminal device is in a system call or a third-party network call and the voice output mode is a speaker mode, the terminal device receives an input triggered by a user to switch the voice output mode of the terminal device to an earphone mode.

Specifically, the voice to be output by the terminal device is a voice in a voice communication process with other terminal devices.

Condition 2: and the user triggers the terminal equipment to play voice.

It will be appreciated that one or more voices are stored in a voice player (e.g., voice memo) or communication application in the terminal device.

Optionally, the terminal device determines whether the condition 2 is satisfied, and may perform the following steps: the terminal equipment receives the input of the voice which is triggered by the user to output by the terminal equipment and stored by the terminal equipment.

It can be understood that the terminal device meets the condition of the voice to be output, that is, the terminal device is required by the user to output the voice in a private mode.

It should be noted that, in the method for outputting a voice according to the embodiment of the present invention, because the terminal device can determine whether a condition of the voice to be output is satisfied, when the terminal device satisfies the condition, the terminal device controls the sound generating unit closest to the ear of the user to vibrate to drive the screen to generate sound and output the voice, and when the terminal device does not satisfy the condition, the terminal device may not trigger the terminal device to determine the sound generating unit closest to the ear of the user. Therefore, the privacy of the terminal equipment for outputting the voice can be improved, and the resources of the terminal equipment can be saved.
