Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a fill light module and a smart terminal. Background Art

[0002] Mobile terminals are typically equipped with a camera module and a fill light assembly that provides supplemental lighting for the camera module. Existing fill lights use a 9×9 array of lights to achieve a light divergence effect. When a smaller divergence angle is required, only the center light is illuminated. As more lights in the array are illuminated, the divergence angle can be expanded.

[0003] During the process of conceiving and implementing this application, the inventors discovered at least the following problems: Existing array flashes offer limited variation in the fill light diffusion angle, capable of only two or three levels. This means they can only achieve fill light effects within a certain focal length and cannot cover the entire focal length. Furthermore, the flash is covered with a textured lampshade, which detracts from the overall aesthetics. Furthermore, most flashes have a fixed divergence angle, which only ensures fill light effects within close range. At longer distances, light energy loss is significant, making long-range photography ineffective.

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

[0005] The purpose of this application is to provide a fill light module that can adjust the divergence angle of light and meet the fill light effect of various shooting distances of the camera module.

[0006] In order to solve the above technical problems, the present application provides a fill light module, including a lens part, an elastic part, a light source and a driving part. The lens part and the elastic part are arranged on the light emitting side of the light source. The driving part is used to drive the lens part and the elastic part to press against each other to change the light divergence angle of the light source.

[0008] Optionally, the elastic portion is disposed between the lens portion and the light source.

[0009] Optionally, the lens portion is disposed between the elastic portion and the light source.

[0010] Optionally, the driving portion is connected between the lens portion and the housing, and the driving portion is used to drive the lens portion to move toward or away from the elastic portion.

[0011] Optionally, the driving portion is connected between the elastic portion and the housing, and the driving portion is used to drive the elastic portion to move toward or away from the lens portion.

[0012] Optionally, the shell includes a base shell and a motor mounting shell, the motor mounting shell is fixed on the base shell, the light passage passes through the base shell and the motor mounting shell, the light source is located in the base shell, the lens part or the elastic part is fixed on the base shell, and the driving part is installed on the motor mounting shell.

[0013] Optionally, the driving portion includes a magnetic component and a coil component, the magnetic component and the coil component are arranged opposite to each other, the magnetic component is connected to the shell, and the coil component is connected to the side wall of the lens portion or the elastic portion.

[0014] Optionally, the fill light module further includes a circuit board, the light source is electrically connected to the circuit board, and the end of the shell is fixed to the circuit board and covers the light source.

[0015] Optionally, the elastic portion includes a liquid silicone sheet.

[0016] Optionally, the elastic portion includes an upper surface and a lower surface that are parallel and oppositely arranged; when the elastic portion and the lens portion are not abutting against each other, the upper surface and the lower surface are both planes; when the elastic portion and the lens portion are abutting against each other, the upper surface and the lower surface are both arc surfaces.

[0017] Optionally, the driving portion is used to adjust a contact area between the elastic portion and the lens portion, and the contact area between the elastic portion and the lens portion is inversely proportional to or directly proportional to a light divergence angle of the light source.

[0018] The present application also provides a smart terminal, comprising the above-mentioned fill light module.

[0019] Optionally, the smart terminal further includes a camera module and a control mainboard, the fill light module and the camera module are electrically connected to the control mainboard respectively, and the control mainboard controls the light divergence angle of the fill light module according to the field of view angle and focal length of the camera module.

[0020] The fill light module of the present application can use a driving unit to drive the lens unit and the elastic unit to abut against each other, thereby changing the surface curvature of the elastic unit to adjust the divergence angle of the light, which can meet the fill light effect of various shooting distances of the camera module. This not only solves the problem that the flash light has a single divergence angle and cannot meet the fill light effect for shooting at multiple distances, but also solves the appearance problem of the flash lampshade being unable to hide the CD pattern. Because the driving unit of the present application drives the elastic unit or lens unit to move to adjust the divergence angle of the light, rather than driving the lampshade to move, the travel of the elastic unit or lens unit is shorter, making the fill light module of the present application smaller in overall size, suitable for mass production, and with a novel appearance and good market competitiveness.

[0043] Figure 1 For a hardware structure diagram of a mobile terminal implementing each embodiment of the present application, please refer to Figure 1 , which is a schematic diagram of the hardware structure of a smart terminal for implementing various embodiments of the present application. The smart terminal 100 may include: an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (audio / video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that Figure 1 The structure of the smart terminal shown in the figure does not constitute a limitation on the smart terminal. The smart terminal may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0044] The following combination Figure 1 A detailed introduction to each component of the smart terminal:

[0045] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution) and 5G, etc.

[0046] WiFi is a short-range wireless transmission technology. Smart terminals can help users send and receive emails, browse web pages, and access streaming media through WiFi module 102. It provides users with wireless broadband Internet access. Figure 1 The WiFi module 102 is shown, but it is understandable that it is not an essential component of the smart terminal and can be omitted as needed without changing the essence of the utility model.

[0047] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the smart terminal 100 is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the smart terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0048] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may 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.

[0049] The smart terminal 100 also includes at least one sensor 105, 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 panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the panel 1061 and / or the backlight when the smart terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described in detail here.

[0050] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a flexible display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0051] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the smart terminal. Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using any suitable object or accessory such as a finger, stylus, etc. on or near the touch panel 1071) and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal caused by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0052] Optionally, the touch panel 1071 may cover the flexible display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the panel 1061 according to the type of touch event. Figure 1 In the figure, the touch panel 1071 and the flexible display panel 1061 are two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 1071 and the flexible display panel 1061 can be integrated to realize the input and output functions of the smart terminal, which is not limited here.

[0053] The interface unit 108 serves as an interface through which at least one external device can be connected to the smart terminal 100. 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, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from the external device and transmit the received input to one or more components within the smart terminal 100, or may be used to transmit data between the smart terminal 100 and the external device.

[0054] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0055] Processor 110 is the control center of the smart terminal, connecting all components of the smart terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the smart terminal and processes data, thereby providing overall monitoring of the smart terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily processes the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0056] The smart terminal 100 may also include a power supply 111 (such as a battery) to supply power to each component. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby managing charging, discharging, and power consumption through the power management system.

[0057] although Figure 1 Not shown, the smart terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

[0058] To facilitate understanding of the embodiments of the present application, the communication network system on which the smart terminal of the present application is based is described below.

[0059] See also Figure 2 , Figure 2 A communication network system architecture diagram is provided for an embodiment of the present application. The communication network system is an LTE system of universal mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203 and an operator's IP service 204, which are connected in sequence.

[0060] Optionally, UE201 may be the above-mentioned terminal 100, which will not be described in detail here.

[0061] E-UTRAN 202 includes eNodeB 2021 and other eNodeBs 2022 . Optionally, eNodeB 2021 may be connected to other eNodeBs 2022 via a backhaul (eg, an X2 interface). eNodeB 2021 is connected to EPC 203 , and eNodeB 2021 may provide access from UE 201 to EPC 203 .

[0062] EPC 203 may include an MME (Mobility Management Entity) 2031, an HSS (Home Subscriber Server) 2032, other MMEs 2033, an SGW (Serving Gate Way) 2034, a PGW (PDN Gate Way) 2035, and a PCRF (Policy and Charging Rules Function) 2036. Optionally, MME 2031 is a control node that processes signaling between UE 201 and EPC 203, providing bearer and connection management. HSS 2032 provides registers for managing functions such as the Home Location Register (not shown) and stores user-specific information such as service features and data rates. All user data can be sent through SGW2034, PGW2035 can provide IP address allocation and other functions for UE 201, PCRF2036 is the policy and charging control policy decision point for service data flow and IP bearer resources, and it selects and provides available policy and charging control decisions for the policy and charging execution function unit (not shown in the figure).

[0063] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem), or other IP services.

[0064] Although the above introduction takes the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but can also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G and future new network systems (such as 6G), etc., which are not limited here.

[0065] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0066] First embodiment

[0067] Figure 3 is a schematic cross-sectional view of the fill light module of the first embodiment of the present application. Figure 4 yes Figure 3 The structural diagram of the fill light module when adjusting the light divergence angle is shown in FIG. Figure 3 and Figure 4 As shown, the fill light module includes a lens portion 12, an elastic portion 13, a light source 14, and a driving portion 15. The lens portion 12 and the elastic portion 13 are disposed on the light-emitting side of the light source 14. The driving portion 15 is used to drive the lens portion 12 and the elastic portion 13 to abut against each other to change the divergence angle of the light from the light source 14. When the light divergence angle needs to be adjusted, the driving portion 15 drives the lens portion 12 and the elastic portion 13 to abut against each other, at which time the elastic portion 13 deforms, and the surface curvature of the elastic portion 13 changes accordingly, thereby adjusting the divergence angle of the light.

[0068] The fill light module of the present application can drive the lens portion 12 and the elastic portion 13 to abut against each other through the driving portion 15, thereby changing the surface curvature of the elastic portion 13 to adjust the divergence angle of the light, which can meet the fill light effect of various shooting distances of the camera module. It not only solves the problem that the flash light divergence angle is single and cannot meet the fill light effect of shooting at multiple distances, but also solves the appearance problem of the flash lampshade being unable to hide the CD pattern. Because the driving portion 15 of the present application drives the elastic portion 13 or the lens portion 12 to move to adjust the divergence angle of the light, rather than driving the lampshade to move, the travel of the elastic portion 13 or the lens portion 12 is shorter, making the fill light module of the present application smaller in overall size, suitable for mass production, and novel in appearance, with good market competitiveness.

[0069] Alternatively, as Figure 3 As shown, the fill light module includes a housing 16, which is provided with a light passage 301. The lens portion 12 and the elastic portion 13 are mounted in the light passage 301 so as to be opposite to each other. The light source 14 is disposed corresponding to the light passage 301. The driving portion 15 is connected to the housing 16 and is used to drive the lens portion 12 or the elastic portion 13 to move. In this embodiment, the light source 14 is located in the housing 16 and at the bottom of the light passage 301. The light emitted by the light source 14 passes through the lens portion 12 and the elastic portion 13 and is emitted from the top of the light passage 301 at a certain divergence angle.

[0070] Alternatively, as Figure 3 As shown, the elastic portion 13 is disposed between the lens portion 12 and the light source 14 , that is, the light emitted by the light source 14 passes through the elastic portion 13 and the lens portion 12 in sequence and then is emitted from the top of the light passage 301 .

[0071] Optionally, a driving portion 15 is connected between the elastic portion 13 and the housing 16, and is used to drive the elastic portion 13 to move toward or away from the lens portion 12. In this embodiment, the elastic portion 13 is in a sheet shape and has a certain thickness. When the elastic portion 13 gradually contacts the lens portion 12, the elastic portion 13 deforms accordingly.

[0072] Optionally, the elastic portion 13 includes an upper surface 131 and a lower surface 132 that are parallel and opposite to each other; when the elastic portion 13 is not in contact with the lens portion 12, the upper surface 131 and the lower surface 132 of the elastic portion 13 are both planes, and at this time, the axis of the light passage 301 is perpendicular to the upper surface 131 and the lower surface 132; when the driving portion 15 drives the elastic portion 13 to abut against the curved surface of the lens portion 12, the upper surface 131 and the lower surface 132 change with the shape, and at this time, the upper surface 131 and the lower surface 132 change from a plane to an arcuate surface; the upper surface 13 The curvature of upper surface 131 and lower surface 132 is related to the contact area between elastic portion 13 and lens portion 12. Specifically, when elastic portion 13 and lens portion 12 first come into contact, the deformation curvature of upper surface 131 and lower surface 132 is small. As the contact area between elastic portion 13 and lens portion 12 gradually increases, the deformation curvature of upper surface 131 and lower surface 132 gradually increases. Driving portion 15 drives elastic portion 13 to move, thereby adjusting the contact area between elastic portion 13 and lens portion 12, thereby adjusting the divergence angle of light and achieving fill-in lighting effects for shooting at multiple distances. In this embodiment, the contact area between elastic portion 13 and lens portion 12 is inversely proportional to the divergence angle of light from light source 14. That is, the larger the contact area between elastic portion 13 and lens portion 12, the smaller the divergence angle of light from light source 14.

[0073] Alternatively, as Figure 3 and Figure 4 As shown, the driving unit 15 includes a magnetic assembly and a coil assembly. The magnetic assembly and the coil assembly are arranged opposite each other. The magnetic assembly is connected to the housing 16, and the coil assembly is connected to the side wall of the elastic portion 13. When the coil assembly is energized, an electromagnetic force is generated between the magnetic assembly and the coil assembly, thereby driving the elastic portion 13 to move up and down along the axis of the light passage 301.

[0074] Optionally, the fill light module further includes a circuit board 17 (PCB), the light source 14 is electrically connected to the circuit board 17 , the driving unit 15 is electrically connected to the circuit board 17 , and the end of the housing 16 is fixed to the circuit board 17 and covers the light source 14 .

[0075] Optionally, the light source 14 is an LED lamp or a lamp group, which can be freely designed according to actual needs.

[0076] Optionally, the elastic portion 13 includes a liquid silicone sheet.

[0080] Second embodiment

[0081] Figure 5 is a schematic cross-sectional view of the fill light module according to the second embodiment of the present application. Figure 6 yes Figure 5 The structural diagram of the fill light module when adjusting the light divergence angle is shown in FIG. Figure 5 and Figure 6 As shown, the fill light module of this embodiment has a substantially similar structure to that of the first embodiment, differing in the positions of the lens portion 12 and the elastic portion 13. In this embodiment, the lens portion 12 is disposed between the elastic portion 13 and the light source 14; the driving portion 15 is connected between the lens portion 12 and the housing 16, and is used to drive the lens portion 12 toward or away from the elastic portion 13.

[0082] When the lens portion 12 is not in contact with the elastic portion 13, the light divergence angle is small. When the driving portion 15 drives the lens portion 12 to abut against the elastic portion 13, so that the upper surface 131 and the lower surface 132 of the elastic portion 13 change from a flat surface to a curved surface, the light divergence angle increases. The contact area between the elastic portion 13 and the lens portion 12 is proportional to the light divergence angle of the light source 14. In other words, the larger the contact area between the elastic portion 13 and the lens portion 12, the larger the light divergence angle of the light source 14.

[0083] Optionally, the magnetic assembly is connected to the housing 16 , and the coil assembly is connected to a side wall of the lens portion 12 .

[0084] Third embodiment

[0085] Figure 7 is a schematic cross-sectional view of the fill light module according to the third embodiment of the present application. Figure 8 yes Figure 7 The structural diagram of the fill light module when adjusting the light divergence angle is shown in FIG. Figure 7 and Figure 8As shown, the fill light module of this embodiment has substantially the same structure as that of the first embodiment, differing in the structure of the housing 16. In this embodiment, the housing 16 includes a bottom housing 161 and a motor mounting housing 162. The motor mounting housing 162 is fixed to the bottom housing 161. A light passage 301 extends through the bottom housing 161 and the motor mounting housing 162. The light source 14 is located in the bottom housing 161. The elastic portion 13 is fixed to the bottom housing 161. The driving portion 15 is mounted on the motor mounting housing 162 and connected between the lens portion 12 and the motor mounting housing 162.

[0086] When the lens portion 12 is not in contact with the elastic portion 13, the light divergence angle is large. When the driving portion 15 drives the lens portion 12 to abut against the elastic portion 13, so that the upper surface 131 and the lower surface 132 of the elastic portion 13 change from a flat surface to a curved surface, the light divergence angle decreases. The contact area between the elastic portion 13 and the lens portion 12 is inversely proportional to the light divergence angle of the light source 14. That is, the larger the contact area between the elastic portion 13 and the lens portion 12, the smaller the light divergence angle of the light source 14.

[0087] Optionally, the magnetic assembly is connected to the motor mounting housing 162 , and the coil assembly is connected to a side wall of the lens portion 12 .

[0088] Optionally, the driving portion 15 is connected between the lens portion 12 and the housing 16 , and the driving portion 15 is used to drive the lens portion 12 to move toward or away from the elastic portion 13 .

[0089] Fourth embodiment

[0090] Figure 9 is a schematic cross-sectional view of the fill light module according to the fourth embodiment of the present application. Figure 10 yes Figure 9 The structural diagram of the fill light module when adjusting the light divergence angle is shown in FIG. Figure 9 and Figure 10 As shown, the fill light module of this embodiment has substantially the same structure as the fill light module of the third embodiment, differing in the positions of the lens portion 12 and the elastic portion 13. In this embodiment, the lens portion 12 is disposed between the elastic portion 13 and the light source 14, and the driving portion 15 is connected between the elastic portion 13 and the housing 16. The driving portion 15 is used to drive the elastic portion 13 to move toward or away from the lens portion 12.

[0091] When the lens portion 12 is not in contact with the elastic portion 13, the light divergence angle is small. When the driving portion 15 drives the lens portion 12 to abut against the elastic portion 13, so that the upper surface 131 and the lower surface 132 of the elastic portion 13 change from a flat surface to a curved surface, the light divergence angle increases. The contact area between the elastic portion 13 and the lens portion 12 is proportional to the light divergence angle of the light source 14. In other words, the larger the contact area between the elastic portion 13 and the lens portion 12, the larger the light divergence angle of the light source 14.

[0092] Optionally, the lens portion 12 is fixed to the bottom housing 161, the elastic portion 13 is mounted on the motor mounting housing 162, and the driving portion 15 is connected between the lens portion 12 and the motor mounting housing 162. In this embodiment, the magnetic component is connected to the motor mounting housing 162, and the coil component is connected to the side wall of the elastic portion 13.

[0093] Fifth embodiment

[0094] The present application also relates to a smart terminal, comprising the above-mentioned fill light module.

[0095] Optionally, the intelligent terminal also includes a camera module and a control motherboard. The fill light module and camera module are electrically connected to the control motherboard, which controls the light divergence angle of the fill light module based on the camera module's field of view and focal length. When shooting, the control motherboard uses software to capture faces, calculates the face's proportion of the frame, and estimates the distance from the subject to the camera module based on the lens' field of view and focal length. It then controls the fill light module to an appropriate light divergence angle, providing even fill light to the subject.

[0096] Since the fill light module of the present application can adjust the divergence angle of light, compared with using the motor of the camera module to directly drive the movement of the lens, it can achieve a shorter stroke and a smaller size.
