Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, specifically to a motor and a smart terminal. Background Technology

[0002] A horizontal axis linear motor is a new type of electric drive device. Smart terminals such as smartphones use horizontal axis linear motors to achieve different tactile effects such as button feedback and game vibration.

[0003] In conceiving and implementing this application, the inventors discovered at least the following problems: In some solutions, a cooling fan is also needed in the smart terminal to reduce the temperature of the core processing area and ensure the performance of the smart terminal. However, simultaneously setting up a horizontal axis linear motor and a cooling fan will occupy a large amount of space, resulting in a larger size of the smart terminal.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a motor and an intelligent terminal.

[0006] To solve the above-mentioned technical problems, this application provides a motor, including: a housing; vibration components disposed inside the housing, wherein at least two vibration components are spaced apart along a first direction, and two adjacent vibration components and the inner wall of the housing define an airflow driving cavity, the airflow driving cavity including an air inlet and an air outlet; and a driving member, which is used to drive two adjacent vibration components to vibrate in the same direction along the first direction, or to drive two vibration components to vibrate in opposite directions along the first direction.

[0007] Optionally, the vibration assembly includes a mass block and a first baffle; a driving member drives the mass block to vibrate; the first baffle extends along a second direction, one end of the first baffle is connected to the mass block, and the other end of the first baffle and both sides of the first baffle along a third direction are slidably engaged with the inner wall of the housing.

[0008] Optionally, the vibration assembly also includes a second baffle, which is disposed on one side surface of the mass block along a third direction, and the second baffle slides in engagement with the inner wall of the housing.

[0009] Optionally, the vibration assembly further includes a second elastic element; a fixing rib is provided in the airflow drive cavity; one end of the second elastic element is connected to the mass block, and the other end of the second elastic element is connected to the fixing rib.

[0010] Optionally, the vibration assembly further defines a mating cavity with the inner wall of the housing. The mating cavity is located on the side of the vibration assembly away from the airflow drive cavity. The vibration assembly also includes a first elastic element located in the mating cavity. One end of the first elastic element is connected to the mass block, and the other end of the first elastic element is connected to the inner wall of the housing.

[0011] Optionally, the mating cavity is provided with a vent.

[0012] Optionally, the driving component includes a motor and two coil groups; the motor is electrically connected to the two coil groups, the coil groups corresponding to the mass block, the coil groups being located on both sides of the mass block along a third direction, and the mass block being magnetic; the motor supplies power to the coil groups to drive the mass block to vibrate.

[0013] Optionally, it also includes a one-way valve, wherein at least one of the air inlet and the air outlet is provided with a one-way valve to allow air to flow from the air inlet to the air outlet.

[0014] This application also provides a smart terminal, including any of the motors described above.

[0015] Optionally, it also includes a central processing unit; the motor's air outlet faces the central processing unit; and the motor's air inlet is connected to the outside of the support terminal.

[0016] As described above, the motor and smart terminal of this application include a motor comprising a housing, vibration components, and a drive component. At least two vibration components are disposed within the inner cavity of the housing. Two adjacent vibration components and the inner wall of the housing together define an airflow drive cavity. The airflow drive cavity has an air inlet communicating with the outside of the smart terminal and an air outlet communicating with the inner cavity of the smart terminal. The drive component controls the vibration components to vibrate at a preset frequency and direction. When the smart terminal requires vibration feedback, the drive component can drive each vibration component to vibrate in the same direction. Simultaneous vibration of multiple vibration components enhances the vibration effect, thus providing good vibration feedback to the smart terminal. When the temperature inside the smart terminal's inner cavity is high, the drive component can drive two adjacent vibration components to vibrate in opposite directions. At this time, the airflow drive cavity will repeatedly expand and contract due to the vibration of the two vibration components, generating airflow. This allows cooler air from outside the smart terminal to enter through the air inlet and be blown into the inner cavity of the smart terminal through the air outlet, thereby achieving a cooling effect. Simultaneously, since the vibration directions of the two adjacent vibration components are opposite, the vibrations generated by the two vibration components cancel each other out. Therefore, the motor as a whole will not vibrate during heat dissipation, avoiding any impact on the user experience of the smart terminal. Therefore, the motor provided in this application can provide both vibration feedback and heat dissipation. Compared with the prior art which sets both a cooling fan and a motor, this application only needs to set one motor in the smart terminal, which helps to free up space in the internal cavity of the smart terminal, improve space utilization, and reduce the size of the smart terminal.

[0031] As the background technology demonstrates, the horizontal axis linear motor is a novel type of electric drive device. Smart terminals such as smartphones use horizontal axis linear motors to achieve different tactile effects such as button feedback and game vibration. In existing technologies, smart terminals also need to include cooling fans to reduce the temperature of the core processing area and ensure the performance of the smart terminal. However, some solutions that simultaneously incorporate both the horizontal axis motor and the cooling fan occupy a significant amount of space, resulting in a larger size for the smart terminal.

[0032] To address the aforementioned technical problems, this application provides a motor and a smart terminal. The motor comprises a housing, vibration components, and a driving component. At least two vibration components are disposed within the inner cavity of the housing, with adjacent vibration components and the inner wall of the housing jointly defining an airflow driving cavity. The airflow driving cavity has an air inlet communicating with the outside of the smart terminal and an air outlet communicating with the inner cavity of the smart terminal. The driving component controls the vibration components to vibrate at a preset frequency and direction. When the smart terminal requires vibration feedback, the driving component can drive each vibration component to vibrate in the same direction. Simultaneous vibration of at least two vibration components enhances the vibration effect, thus providing good vibration feedback to the smart terminal. When the temperature inside the smart terminal's inner cavity is high, the driving component can drive two adjacent vibration components to vibrate in opposite directions. At this time, the airflow driving cavity will repeatedly expand and contract due to the vibration of the two vibration components, generating airflow. This allows cooler air from outside the smart terminal to enter through the air inlet and be blown into the inner cavity of the smart terminal through the air outlet, thereby achieving a cooling effect. Simultaneously, since the vibration directions of the two adjacent vibration components are opposite, the vibrations generated by the two vibration components cancel each other out. Therefore, the motor as a whole will not vibrate during heat dissipation, avoiding any impact on the user experience of the smart terminal. Therefore, the motor provided in this application can provide both vibration feedback and heat dissipation. Compared with the prior art which sets both a cooling fan and a motor, this application only needs to set one motor in the smart terminal, which helps to free up space in the internal cavity of the smart terminal, improve space utilization, and reduce the size of the smart terminal.

[0033] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings:

[0034] It should be noted that the motor provided in this application embodiment can be applied to various smart terminals.

[0035] See Figure 1 , Figure 4 and Figure 5As shown, the motor 100 of this embodiment is used in a smart terminal 10 and includes: a housing 110, a vibration assembly 120, and a driving member (not shown in the figure). The vibration assembly 120 is disposed inside the housing 110, and at least two vibration assemblies 120 are spaced apart along a first direction. Two adjacent vibration assemblies 120 and the inner wall of the housing 110 together define an airflow driving cavity 111. The airflow driving cavity 111 has an air inlet 1111 and an air outlet 1112. The air inlet 1111 communicates with the outside of the smart terminal 10, and the air outlet 1112 communicates with the inner cavity of the smart terminal 10. The driving member is used to drive two adjacent vibration assemblies 120 to vibrate in the same direction along the first direction to make the motor 100 vibrate, or to drive two adjacent vibration assemblies 120 to vibrate in opposite directions along the first direction to make the motor 100 blow air into the inner cavity of the smart terminal 10 through the air outlet 1112. Optionally, Figure 1 and Figure 2 The X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction.

[0036] In this embodiment, the driving component can drive each vibration component 120 to vibrate at a certain frequency and direction. When the driving component drives each vibration component 120 to vibrate in the same direction and at the same frequency, the vibration of at least two vibration components 120 has a strengthening effect, thus manifesting as the overall vibration of the motor 100, thereby providing vibration feedback to the smart terminal 10. The vibration frequency of each vibration component 120 can be adjusted according to different vibration requirements. The specific frequency is not limited in this embodiment.

[0037] Optionally, the number of vibration components 120 is not limited in this embodiment. Optionally, the number of vibration components 120 can be even. When the driving member drives any two adjacent vibration components 120 to vibrate at the same frequency but in opposite directions, the vibrations of any two adjacent vibration components 120 can cancel each other out, so the motor 100 as a whole will not vibrate, that is, the user will not feel the vibration of the motor 100 when using the smart terminal 10. However, since the vibration directions of the two vibration components 120 are always opposite, the airflow drive cavity 111 located between the two vibration components 120 will repeatedly increase or decrease. When the two vibration components 120 move in opposite directions, the air pressure inside the airflow drive cavity 111 decreases, and the cooler air outside the smart terminal 10 enters the airflow drive cavity 111 through the air inlet 1111. When the two vibration components 120 move toward each other, the air in the airflow drive cavity 111 is compressed and blown into the inner cavity of the smart terminal 10 through the air outlet 1112. The two vibration components 120 vibrate continuously, and the above process is repeated continuously, thereby achieving the effect of continuously blowing air into the inner cavity of the smart terminal 10, thus realizing the heat dissipation of the smart terminal 10.

[0038] Optionally, the number of vibration components 120 can also be odd. Optionally, taking three vibration components 120 as an example, vibration feedback can be generated when all vibration components 120 vibrate in the same direction. When the vibration directions of the first and third vibration components 120 along the first direction are opposite to those of the second vibration component 120, the airflow drive cavity 111 does not increase or decrease, thereby achieving heat dissipation. However, since the number of vibration components 120 vibrating in the two directions is different, it is necessary to calculate and adjust the vibration frequency of each of the three vibration components 120 to ensure that the vibrations of the three vibration components 120 can cancel each other out during the heat dissipation process, thus avoiding vibration of the smart terminal 10. The quantitative relationship of the frequencies between each vibration component 120 needs to be reasonably set according to the specific number of vibration components 120, and this embodiment does not limit this.

[0039] Therefore, the motor 100 provided in this application embodiment has two working modes. In one working mode, the motor 100 vibrates at a certain frequency to provide different vibration feedback such as button feedback and game vibration. In the other working mode, the motor 100 does not vibrate but only blows air into the inner cavity of the smart terminal 10 to dissipate heat, ensuring the working performance of the smart terminal 10. Compared with the prior art that installs both the motor 100 and the cooling fan, the motor 100 in this application embodiment occupies less space, which helps to free up space inside the smart terminal 10, improve space utilization, reduce the size of the smart terminal 10, and thus improve the user experience of the smart terminal 10.

[0040] Optionally, the smart terminal 10 includes a central processing unit (not shown in the figure). Since the central processing unit is the main source of temperature rise when the smart terminal 10 is working, the motor 100 can be installed close to the central processing unit, with the air outlet 1112 of the motor 100 facing the central processing unit. This allows the air outlet 1112 to blow air directly onto the central processing unit, which helps improve the heat dissipation efficiency of the motor 100, prevents the performance of the smart terminal 10 from degrading due to overheating, and improves the usability of the smart terminal 10.

[0041] Optionally, an air duct (not shown in the figure) communicating with the air outlet 1112 can be provided in the inner cavity of the smart terminal 10 to ensure that the air blown out of the air outlet 1112 can flow along the air duct and eventually flow out of the smart terminal 10, thereby blowing out the hot air in the inner cavity of the smart terminal 10 and ensuring air circulation in the inner cavity. Of course, the specific structure of the air duct is not limited in this embodiment of the application, and can be reasonably selected according to the specific structure of the smart terminal 10.

[0042] See also some of the possible implementation methods. Figure 1 and Figure 2As shown, the vibration assembly 120 of this application embodiment includes a mass block 121 and a first baffle 122; a driving member drives the mass block 121 to vibrate; the first baffle 122 extends along a second direction, one end of the first baffle 122 is connected to the mass block 121, and the other end of the first baffle 122 and both sides of the first baffle 122 along a third direction are slidably engaged with the inner wall of the housing 110.

[0043] Optionally, each side of the first baffle 122 is slidably engaged with the inner wall of the housing 110. On the one hand, this can reduce the resistance encountered by the vibration component 120 during vibration, ensuring that the vibration component 120 vibrates at a stable frequency. On the other hand, it can ensure the sealing of the airflow drive cavity 111, ensuring that air can only flow through the air inlet 1111 and the air outlet 1112, thereby ensuring the heat dissipation effect when the two vibration components 120 vibrate in opposite directions.

[0044] See also some of the possible implementation methods. Figure 1 , Figure 4 and Figure 5 As shown, the driving component in this embodiment includes a motor and at least two coil groups; the motor is electrically connected to each coil group, the coil groups correspond to the mass block 121, the coil groups are located on both sides of the mass block 121 along a third direction, and the mass block 121 is magnetic; the motor supplies power to the coil groups to drive the mass block 121 to vibrate.

[0045] Optionally, the coil group generates a corresponding induced magnetic field after being energized. Since the mass block 121 is magnetic, the generated induced magnetic field will drive the mass block 121 to move along the first direction. When alternating current is applied to the coil group, the direction of the induced magnetic field generated by the coil group changes continuously, while the magnetic poles of the mass block 121 remain unchanged. Therefore, the mass block 121 moves back and forth along the first direction under the drive of the changing magnetic field, thereby driving the mass block 121 to vibrate. Since the motor 100 needs to drive two adjacent mass blocks 121 to vibrate in opposite directions when heat dissipation is required, at least two coil groups are required, each coil group corresponding to one mass block 121. When the motor applies a current of the same phase to each coil group, the mass blocks 121 vibrate in the same direction, and the motor 100 provides vibration feedback. When the motor applies a current of the opposite phase to any two adjacent coil groups, the two adjacent mass blocks 121 vibrate in opposite directions, and the motor 100 blows air into the inner cavity of the smart terminal 10 to achieve heat dissipation.

[0046] Optionally, the coil group may include at least two coils, which are respectively arranged on both sides of the mass block 121 along a third direction to drive the vibration of the mass block 121. The specific number of coils is not limited in this embodiment and can be reasonably arranged according to the actual size of the motor 100 and the mass block 121.

[0047] See also some of the possible implementation methods. Figure 1 , Figure 2 and Figure 4 As shown, the vibration assembly 120 in this embodiment of the application further includes a second baffle 123. The second baffle 123 is disposed on one side surface of the mass block 121 along a third direction, and the second baffle 123 slides in cooperation with the inner wall of the housing 110.

[0048] Optionally, since different smart terminals 10 have different vibration requirements, mass blocks 121 of different sizes need to be matched based on the vibration requirements. When the height of the mass block 121 along the third direction is low, there will be some gap between the mass block 121 and the inner wall of the housing 110, which will affect the sealing of the airflow drive cavity 111. Therefore, a second baffle 123 can be provided on one side surface of the mass block 121 along the third direction to ensure the sealing of the airflow drive cavity 111 and improve the heat dissipation effect of the motor 100.

[0049] Optionally, both the first baffle 122 and the second baffle 123 can be made of rigid components to reduce wear when they slide relative to the housing 110, which helps to extend the service life of the motor 100.

[0050] See also some of the possible implementation methods. Figure 1 As shown, at least two vibration components 120 in this embodiment are arranged sequentially along a first direction. The two vibration components 120 located at the first and last ends also define a mating cavity 113 with the inner wall of the housing 110. The mating cavity 113 is located on the side of the vibration component 120 away from the airflow drive cavity 111. The vibration component 120 also includes a first elastic element 124, which is located in the mating cavity 113. One end of the first elastic element 124 is connected to the mass block 121, and the other end of the first elastic element 124 is connected to the inner wall of the housing 110.

[0051] Optionally, the first elastic element 124 can serve as a support and buffer. When the coil group drives the mass block 121 to vibrate, the first elastic element 124 can prevent the mass block 121 from colliding with the inner wall of the housing 110, reducing the damage caused by vibration to the mass block 121 and the housing 110, which is beneficial to improving the service life of the motor 100. At the same time, the spring can absorb and release a certain amount of energy, making the vibration of the mass block 121 more stable and continuous, which is beneficial to improving the vibration effect of the motor 100.

[0052] Alternatively, the spring can also help reduce the noise generated during the vibration process, making the movement of the mass block 121 more flexible and controllable, thereby producing a more delicate vibration effect.

[0053] See also some of the possible implementation methods. Figure 1As shown, the vibration assembly 120 in this embodiment of the application further includes a second elastic member 125; a fixing rib 112 is provided in the airflow drive cavity 111; one end of the second elastic member 125 is connected to the mass block 121, and the other end of the second elastic member 125 is connected to the fixing rib 112.

[0054] Optionally, the second elastic element 125 can prevent the two mass blocks 121 from colliding when vibrating in opposite directions, thereby reducing the wear and tear on the mass blocks 121. At the same time, a fixing rib 112 is required to provide a fixing surface for the second elastic element 125. The fixing rib 112 can be set at the middle of the two mass blocks 121 along the first direction to ensure that the distance between the two mass blocks 121 and the fixing rib 112 is equal when the mass blocks 121 are stationary.

[0055] Optionally, in order to ensure that the airflow drive cavity 111 is not blocked, the fixing rib 112 needs to be set such that there is a gap between the fixing rib 112 and at least one inner wall of the housing 110 along the third direction. Optionally, the length of the fixing rib 112 along the second direction is shorter than the length of the housing 110 along the second direction. The specific shape of the fixing rib 112 is not limited in this embodiment, as long as it is ensured that the two sides of the fixing rib 112 along the first direction can be connected.

[0056] See also some of the possible implementation methods. Figure 1 , Figure 4 and Figure 5 As shown, the embodiments of this application also include a one-way valve 1111a, and at least one of the air inlet 1111 and the air outlet 1112 is provided with a one-way valve 1111a so that air flows from the air inlet 1111 to the air outlet 1112.

[0057] Optionally, a one-way valve 1111a is provided at the air outlet 1112 and the air inlet 1111. When the two mass blocks 121 move in opposite directions, outside air enters the airflow drive chamber 111 through the air inlet 1111. When the two mass blocks 121 move towards each other, the gas in the airflow drive chamber 111 enters the inner cavity of the smart terminal 10 through the air outlet 1112. This ensures that the air flows in one direction within the motor 100, blowing the cooler air from outside the smart terminal 10 into the inner cavity of the smart terminal 10. This helps to ensure the effect of the motor 100 blowing air into the inner cavity and improves the heat dissipation efficiency of the motor 100.

[0058] See also some of the possible implementation methods. Figure 1 As shown, the mating cavity 113 in this embodiment of the application is provided with a vent hole (not shown in the figure).

[0059] Optionally, during the vibration of the vibration assembly 120, the distance between the vibration assembly 120 and the side wall of the housing 110 along the first direction is constantly changing, and the mating cavity 113 is also repeatedly expanding and shrinking. Therefore, it is necessary to provide a vent hole in the mating cavity 113 to ensure the air pressure balance in the mating cavity 113 and ensure that the motor 100 can operate safely and stably.

[0060] See Figure 1 , Figure 4 and Figure 5 As shown, this application embodiment also provides a smart terminal 10, including any of the motors 100 described above.

[0061] It should be noted that the structure and operation of the motor 100 have been described in detail in the above embodiments, and will not be repeated here.

[0062] In this embodiment of the application, by setting the motor 100, the smart terminal 10 can obtain rich vibration feedback in different scenarios. At the same time, when the temperature of the smart terminal 10 is high, the motor 100 can be activated in time to dissipate heat from the smart terminal 10, ensuring the performance of the smart terminal 10. There is no need to install an additional heat dissipation device in the smart terminal 10, so the size and weight of the smart terminal 10 can be reduced, and the user experience of the smart terminal 10 can be improved.

[0063] Optionally, the motor 100 provided in this embodiment includes a housing 110, a drive member, and at least two vibration components 120. An airflow drive cavity 111 is formed between two adjacent vibration components 120. The airflow drive cavity 111 has an air inlet 1111 and an air outlet 1112. When installing the motor 100, the air inlet 1111 of the motor 100 is configured to communicate with the outside of the smart terminal 10, and the air outlet 1112 is configured to face the central processing unit of the smart terminal 10 and communicate with the inner cavity of the smart terminal 10. The motor 100 has two working modes. In one working mode, the drive member drives each vibration component 120 to vibrate in the same direction. In this way, the motor 100 as a whole vibrates, thereby providing vibration feedback such as button feedback and game vibration to the smart terminal 10. In the other working mode, the drive member drives any two adjacent vibration components 120 to vibrate in opposite directions. In this way, the airflow drive cavity 111 will repeatedly expand and contract, thereby drawing air from outside the smart terminal 10 into the airflow drive cavity 111 through the air inlet 1111, and then blowing it towards the central processing unit through the air outlet 1112, thus achieving the function of heat dissipation and cooling. At the same time, the vibrations of the two adjacent vibration components 120 cancel each other out, and the motor 100 as a whole will not vibrate. Therefore, when the motor 100 is dissipating heat, the user of the smart terminal 10 will not feel the vibration, and it will not affect the user experience of the smart terminal 10. Therefore, the motor 100 provided in this embodiment can provide both vibration feedback and heat dissipation and cooling, eliminating the need to install additional heat dissipation devices such as cooling fans inside the smart terminal 10. This helps to save space, reduce the size and weight of the smart terminal 10, and thus improve the user experience of the smart terminal 10.

[0064] Optionally, the smart terminal 10 can be implemented in various forms. For example, the smart terminal 10 described in this application may include mobile terminals such as mobile phones, tablets, laptops, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs, desktop computers, etc.

[0065] The following description will use a mobile terminal as an example. Those skilled in the art will understand that, apart from elements specifically designed for mobile purposes, the construction according to the embodiments of this application can also be applied to fixed-type terminals.

[0066] Please see Figure 3 , Figure 3This is a schematic diagram of the hardware structure of a mobile terminal provided in various embodiments of this application. The mobile terminal 200 may include: an RF (Radio Frequency) unit 201, a WiFi module 202, an audio output unit 203, an A / V (Audio / Video) input unit 204, a sensor 205, a display unit 206, a user input unit 207, an interface unit 208, a memory 209, a processor 210, and a power supply 211, etc. Those skilled in the art will understand that... Figure 3 The mobile terminal structure shown does not constitute a limitation on the mobile terminal. The mobile terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0067] The following is combined with Figure 3 A detailed introduction to each component of the mobile terminal:

[0068] The radio frequency (RF) unit 201 can be used for receiving and transmitting signals during information transmission or calls. Optionally, it receives downlink information from the base station and processes it with the processor 210; additionally, it transmits uplink data to the base station. Typically, the RF unit 201 includes, but is not limited to, an antenna and an RF control module. Optionally, the RF control module may include at least one amplifier, transceiver, coupler, low-noise amplifier, duplexer, etc. Furthermore, the RF unit 201 can also communicate wirelessly with networks and other devices. The aforementioned wireless communications may use any communication standard or protocol, including but not limited to Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access 2000 (CDMA2000), Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Frequency Division Duplexing-Long Term Evolution (FDD-LTE), Time Division Duplexing-Long Term Evolution (TDD-LTE), 5G, and 6G.

[0069] Wireless Fidelity (WiFi) is a short-range wireless transmission technology. Mobile terminals using the WiFi module 202 can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 3 The WiFi module 202 is shown, but it is understood that it is not a necessary component of the mobile terminal and can be omitted as needed without changing the essence of the utility model.

[0070] The audio output unit 203 can convert audio data received by the radio frequency unit 201 or the WiFi module 202 or stored in the memory 209 into audio signals and output them as sound when the mobile terminal 200 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 203 can also provide audio output related to specific functions performed by the mobile terminal 200 (e.g., call signal receiving sound, message receiving sound, etc.). The audio output unit 203 may include a speaker, a buzzer, etc.

[0071] The A / V input unit 204 is used to receive audio or video signals. The A / V input unit 204 may include a graphics processing unit (GPU) 2041 and a microphone 2042. The GPU 2041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 206. The image frames processed by the GPU 2041 can be stored in the memory 209 (or other storage media) or transmitted via the radio frequency unit 201 or the WiFi module 202. The microphone 2042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 201 in telephone call mode. The microphone 2042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0072] The mobile terminal 200 also includes at least one sensor 205, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 2061 according to the ambient light level, and the proximity sensor can turn off the display panel 2061 and / or backlight when the mobile terminal 200 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0073] The display unit 206 is used to display information input by the user or information provided to the user. The display unit 206 may include a display panel 2061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0074] User input unit 207 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the mobile terminal. Optionally, user input unit 207 may include touch panel 2071 and other input devices 2072. Touch panel 2071, also known as touch screen, can collect touch operations on or near the user (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 2071), and drive corresponding connection devices according to a pre-set program. Touch panel 2071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 210, and can receive and execute commands from processor 210. In addition, touch panel 2071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 2071, the user input unit 207 may also include other input devices 2072. Optionally, other input devices 2072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0075] Optionally, the touch panel 2071 may cover the display panel 2061. When the touch panel 2071 detects a touch operation on or near it, it transmits the information to the processor 210 to determine the type of touch event. Subsequently, the processor 210 provides corresponding visual output on the display panel 2061 based on the type of touch event. Although in Figure 3 In this embodiment, the touch panel 2071 and the display panel 2061 are two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 2071 and the display panel 2061 can be integrated to realize the input and output functions of the mobile terminal. The specific implementation is not limited here.

[0076] Interface unit 208 serves as an interface through which at least one external device can connect to mobile terminal 200. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, and so on. Interface unit 208 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within mobile terminal 200, or it may be used to transmit data between mobile terminal 200 and the external device.

[0077] The memory 209 can be used to store software programs and various data. The memory 209 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 209 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0078] Processor 210 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in memory 209, and by calling data stored in memory 209, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. Processor 210 may include one or more processing units; preferably, processor 210 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into processor 210.

[0079] The mobile terminal 200 may also include a power supply 211 (such as a battery) that supplies power to various components. Preferably, the power supply 211 can be logically connected to the processor 210 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0080] although Figure 3 As not shown, the mobile terminal 200 may also include a Bluetooth module, etc., which will not be described in detail here.
