[0002] In current various application scenarios, such as knowledge-intensive activities like online meetings, remote teaching, or interviews, the demand for the recording function is increasing day by day. However, some existing mobile phone holders do not have the function of assisting in recording. Especially for those mobile phone users who do not support the recording function themselves, this defect is particularly obvious. These users often need to rely on external recording devices to meet their recording needs, but such solutions have many inconveniences.

[0003] On the one hand, when using an external recording device, in order to ensure the recording quality, users often need to constantly adjust the angle and position of the recording device, which is not only cumbersome but also greatly restricts the user's freedom of movement. On the other hand, carrying an additional recording device also increases the burden, especially in the case where multiple devices need to be operated simultaneously, which further exacerbates the difficulty of use.

[0021] The present disclosure will be further described in detail below with reference to the drawings and examples. It can be understood that the specific examples described herein are only for explaining the relevant content and are not intended to limit the present disclosure. Additionally, it should be noted that for the sake of description, only parts related to the present disclosure are shown in the drawings.

[0022] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] In current various application scenarios, such as knowledge-intensive activities like online meetings, remote teaching, or interviews, the demand for the recording function is increasing day by day. However, some existing mobile phone holders do not have the function of assisting in recording. Especially for those mobile phone users who do not support the recording function themselves, this defect is particularly obvious. These users often need to rely on external recording devices to meet their recording needs, but such solutions have many inconveniences. On the one hand, when using an external recording device, in order to ensure the recording quality, users often need to constantly adjust the angle and position of the recording device, which is not only cumbersome but also greatly restricts the user's freedom of movement. On the other hand, carrying an additional recording device also increases the burden, especially in the case where multiple devices need to be operated simultaneously, which further exacerbates the difficulty of use.

[0024] For this reason, the present disclosure proposes a mobile phone holder.

[0025] The mobile phone holder at least includes a holder main body, a scene determination module, a microphone module, and a recording module. The holder main body is detachably arranged on the back plate of the mobile phone for supporting the mobile phone. The scene determination module is arranged on the holder main body for determining the recording scene of the mobile phone. The microphone module is arranged on the holder main body and connected to the scene determination module for calling the microphone array corresponding to the recording scene to collect voice signals. The recording module is arranged on the holder main body and connected to the microphone module for recording the voice signals.

[0026] The mobile phone holder of the present disclosure is closely attached to the back plate of the mobile phone and can determine the microphone array suitable for collecting voice signals according to the recording scene. Then it calls the corresponding microphone array to collect voice signals, and the recording module records this. It ensures the adaptability to different recording scenes and improves the clarity of recording in various scenes.

[0027] The mobile phone holder of the present disclosure solves the problem that some mobile phone models cannot record, and avoids problems such as the need to adjust the angle or the existence of movement restrictions for external recording devices. Moreover, through the scene determination module of the present disclosure, it can automatically analyze and identify different recording environments. And according to the characteristics of different recording scenes such as on-site recording and call recording, it determines the most suitable microphone array for collecting and recording voice signals, which not only meets the high-standard requirements of users for recording effects in various scenes, but also greatly reduces the use threshold, avoids the possible selection errors when manually switching modes, and effectively prevents the missed recording of important recordings due to mode mismatch.

[0028] Figure 1 It is a schematic structural diagram of a mobile phone holder according to an embodiment of the present disclosure.

[0029] Such as Figure 1As shown, the external structure of the mobile phone holder 100 is presented from the perspective of a side view. At least the first main body 110a, the second main body 110b, the microphone module 120, the assembly component 130, the interface 140, and the control button 150 can be seen from the outside of the mobile phone holder 100.

[0030] It should be noted that the mobile phone holder 100 is only one form of the mobile phone holder disclosed in the present disclosure, and mobile phone holders of other forms with the same modules all fall within the protection scope of the present disclosure.

[0031] The first main body 110a and the second main body 110b constitute the holder main body (not shown in the figure). In the first main body 110a, various functional components such as a microphone module, an interface, a control button, a recording module, a storage unit, and a power module can be embedded. One side of the first main body 110a is fixedly connected to the assembly component 130, and through this assembly component 130, the holder main body can be detachably mounted on the back panel of the mobile phone.

[0032] A scene determination module can be embedded in the second main body 110b. The second main body 110b is connected to one end of the first main body 110a away from the assembly component 130, and this connection is rotatable. Specifically, the first main body 110a and the second main body 110b are connected by a hinge component (not shown in the figure), allowing the second main body 110b to rotate away from the first main body 110a around the hinge component, thereby forming an adjustable angle between the two.

[0033] When the first main body 110a is mounted on the back panel of the mobile phone via the assembly component 130, by adjusting the angle between the second main body 110b and the first main body 110b, the mobile phone can be supported at a specific angle and maintain this angle with the surface in contact with the second main body 110b. This design not only provides flexible angle adjustment but also ensures the stability and convenience of device use.

[0034] The first main body 110a can be designed in the shape of a hexagonal prism or any other suitable geometric shape to adapt to different usage requirements and aesthetic preferences. The assembly component 130 can be designed in the shape of a cylinder or any other shape to facilitate matching with different mobile phone back panels. The size of the assembly component 130 needs to match the size of the first main body 110a to ensure that the entire holder main body can be firmly mounted on the mobile phone, thereby ensuring the stability and safety of use.

[0035] The second main body 110b can be in the shape of a circular ring or any other form. Especially when it is designed as a ring, it can provide a better hand feeling and is convenient for users to hold.

[0036] To ensure portability and durability, both the first body 110a and the second body 110b can be made of lightweight and sturdy materials, and the specific material selection will be determined according to the design requirements. In addition, an anti-slip pad can be configured on the side of the second body 110b away from the first body 110a, so as to effectively prevent sliding when placed on a flat surface such as a table, thereby improving the stability and safety of the mobile phone support.

[0037] The assembly component 130 can be made of materials such as magnets, enabling the bracket body to be conveniently and firmly installed on the back panel of the mobile phone while maintaining a high degree of detachability, facilitating users to quickly install or remove the bracket as needed. This design not only improves the convenience of use but also ensures the safety and stability of the device.

[0038] The microphone module 120 is provided on the bracket body and can be provided on the first body 110a. The microphone unit of the microphone module 120 can be exposed outside the first body 110a to ensure the clarity during the voice signal acquisition process. Additionally, the microphone module 120 can include a directional microphone array and an omnidirectional microphone array.

[0039] In Figure 1 The microphone array shown can be either part of the omnidirectional microphone array or a specifically designed directional microphone array. The directional microphone array consists of multiple microphone units and is specifically used to collect voice signals from a specific direction, ensuring a high degree of sensitivity and clarity to the sound in that direction; while the omnidirectional microphone array is evenly distributed around the first body 110a and can capture sounds in the environment omnidirectionally and multi-angularly, providing richer audio information.

[0040] The directional microphone array can either exist as a component of the omnidirectional microphone array or be independently configured to meet different recording requirements. This flexibility enables the device to adjust its microphone configuration according to the specific application scenario, whether it is focused on sound collection in a single direction or comprehensive coverage of environmental sound effects, and can handle it with ease. Therefore, regardless of the type of microphone array, it aims to improve the recording quality and adapt to diverse usage scenarios, providing users with the best recording experience.

[0041] The microphone module 120 is electrically connected to the scene determination module, and the two work together to automatically select the most suitable type of microphone array according to the specific recording scene. When the recording scene requires focusing on a sound source in a specific direction, the microphone module 120 will automatically enable the directional microphone array (such as in the case of call recording); while when it is necessary to capture omnidirectional environmental sounds (such as in the case of on-site recording), it will switch to the omnidirectional microphone array.

[0042] In the case of using a directional microphone array, the microphone module 120 can not only identify the direction that needs to be focused on, but also accurately adjust the direction of the directional microphone array according to the specific position of the sound source in the recording scene to ensure the best sound collection effect. This selection and adjustment mechanism ensures that the optimal audio capture effect can be achieved in any recording environment, greatly improving the clarity and professionalism of the recording. In this way, users can enjoy a high-quality and adaptable recording experience without manual intervention.

[0043] The interface 140 is provided on the bracket main body and can be provided on the first main body 110a. The interface 140 can be a physical interface such as a USB (Universal Serial Bus) interface or a Type-C interface, which is used to transmit the voice signals recorded by the recording module to an external device for subsequent processing of these signals. The interface 140 can also be used as a charging interface for the power module and can support fast and effective charging of the power module. The design of the interface 140 fully considers the diverse needs of users and provides a convenient and efficient solution whether it is to ensure the battery life of the device or to facilitate data management and sharing. Such a design enhances the overall flexibility and practicality of the device, making the user operation experience smoother and more efficient.

[0044] The control button 150 is provided on the bracket main body and can be provided on the first main body 110a. The control button 150 corresponds to control instructions, such as a start instruction, a pause instruction, and a stop instruction, etc. The control button 150 is electrically connected to the recording module and can control the recording module to start, pause, or stop the recording function.

[0045] When only one control button 150 is configured, the specific control instruction can be determined by identifying the duration of the first operation performed on the button. For example, if the control button 150 is pressed briefly (for 1 second), the pause or resume instruction is triggered; if it is long-pressed (for 5 seconds), the start or stop instruction is triggered. The first operation here can be in the form of a click, a press, or a voice command, etc., and the specific form is not limited, aiming to provide flexible operation options.

[0046] In the case where multiple control buttons 150 are configured, each button can individually correspond to a specific control instruction, enabling users to operate more directly. The number of control buttons can be matched with the number of control instructions according to actual needs, or some control instructions can be designed to share the same button to simplify the interface layout and reduce the number of physical buttons.

[0047] This flexible design not only improves the user's operation convenience but also ensures the ease of use and adaptability of the device. Whether for ordinary users who pursue a simple operation experience or professionals who require quick responses, they can all find an operation method suitable for themselves. In this way, single or multiple control buttons 150 can efficiently meet various control requirements and enhance the user experience.

[0048] The scene determination module can be arranged inside the bracket main body, such as in the second main body, and is used to determine the recording scene. The scene determination module is electrically connected to the microphone module 120 and can synchronize the determined recording scene to the microphone module 120, so that the microphone module 120 can determine the pickup mode and then call the directional microphone array or the omnidirectional microphone array to collect clear and lossless voice signals.

[0049] The scene determination module is built-in with at least one sensor unit, and the sensor unit can be one or more of a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer. Of course, the sensor unit can also be a Hall sensor or an optical sensor, which is not limited here.

[0050] The way for the scene determination module to determine the recording scene can be: according to the three-axis accelerometer, determine the first inclination angle of the bracket main body, where the first inclination angle is the inclination angle between the main body extension direction of the bracket main body and the gravity direction; according to the three-axis gyroscope, determine the angular pulse state of the bracket main body, and the angular pulse state represents the position change state of the bracket main body; according to the three-axis magnetometer, determine the magnetic field state of the bracket main body along the target axis direction, and the magnetic field state represents the position change state of the bracket main body; when the first inclination angle is less than the inclination angle threshold, the angular pulse state is a sudden increase, and the magnetic field state is a sudden increase, then determine that the bracket main body is in the second posture.

[0051] Among them, when the mobile phone bracket is installed on the back panel of the mobile phone, place the mobile phone perpendicular to the ground. The X-axis is parallel to the ground and perpendicular to the Y-axis, the Y-axis is parallel to the ground and points away from the mobile phone from the mobile phone bracket, and the Z-axis is perpendicular to the ground.

[0052] The Hall sensor is a sensor based on the Hall effect. It can detect changes in the magnetic field intensity to sense the relative position or proximity between objects. The Hall sensor can be used to detect changes in the distance between the bracket and the back panel of the mobile phone. When the second main body approaches the back panel of the mobile phone, the Hall sensor can sense this change and determine it as the second posture. Otherwise, it is determined as the first posture.

[0053] Optical sensors utilize the properties of light to detect changes in the environment, such as light intensity, color, or the presence of objects. In a mobile phone holder, the optical sensor can be used to monitor environmental changes around the holder or directly detect the relative position between the holder and the mobile phone. If the light is strong, it indicates that the mobile phone holder is in the first posture and the second body is exposed to the outside. If the light is weak, it indicates that the mobile phone holder is in the second posture and the second body coincides with the first body.

[0054] The mobile phone holder of the present disclosure not only solves the problem that some models of mobile phones cannot record, avoids the problems that external recording devices need to adjust the angle or have movement restrictions, but also adapts to the environmental characteristics of the recording scene through the selection of the microphone array, improving the recording effect.

[0055] Figure 2 It is an architecture diagram of a mobile phone holder according to an embodiment of the present disclosure. The following will be combined with Figure 2 to describe the overall architecture of the mobile phone holder 200 in detail.

[0056] It should be noted that the mobile phone holder 200 can be the same as or similar to the mobile phone holder 100. When the mobile phone holder 200 is the same as the mobile phone holder 100, the main body holder 210 can be composed of the first holder 110a and the second holder 110b, the microphone module 220 can be the microphone module 120, the assembly component 230 can be the assembly component 130, the interface 240 can be the interface 140, and the control button 250 can be the control button 150, which is not limited here.

[0057] The holder main body 210 is composed of a first body and a second body, and the two are rotatably connected through a hinge assembly. This design allows the second body to rotate around the hinge assembly away from the first body and the assembly component 230, thereby forming an angle adjustable within the range of 0 to 180 degrees between the two. When the angle is 0 degrees, it means that the first body and the second body completely coincide; when the angle reaches 180 degrees, it means that the two bodies are in a non-coincident but coplanar state.

[0058] During a mobile phone call, usually the holder main body remains in a closed state, that is, the first body and the second body are in the same plane, which is convenient for the user to hold and use. On the contrary, if the angle formed between the first body and the second body is greater than 0 degrees and less than 180 degrees, it indicates that the holder main body is in an open state, which is suitable for non-call scenarios, such as conference calls, etc. In this case, the mobile phone can be stably placed on the desktop or other planes through the holder, providing stable support and comfortable angle adjustment to meet different usage requirements.

[0059] The microphone module 220 is disposed in the bracket main body 210, which may be inside the first main body. However, the microphone unit of the microphone module 220 should be exposed to the outer surface of the bracket main body 210 to collect sound signals without loss.

[0060] The microphone module 220 may include a plurality of microphone units, and these microphone units may form a directional microphone array and an omnidirectional microphone array.

[0061] The assembly component 230 is disposed on the bracket main body 210, usually on the side of the first main body of the bracket main body 210 away from the second main body. The assembly component 230 may be made of a material such as a magnet so that the bracket main body 210 can be conveniently and detachably mounted on the back panel of the mobile phone.

[0062] The interface 240 is disposed on the bracket main body 210, which may be the outer surface of the first main body of the bracket main body 210, to synchronize the voice signal recorded by the recording module 270 to an external device. Alternatively, the interface 240 can also serve as a charging interface for the power module 290 to supply power to it. The interface 240 may be a USB interface or a type-C interface, etc., and the form of the interface is not limited to meet various usage requirements.

[0063] The control button 250 may be disposed on the bracket main body 210, which may be the outer surface of the first main body of the bracket main body 210, so that the user can perform a first operation on it according to needs to trigger a corresponding control instruction. The number of the control buttons 250 is not limited, and the way of triggering the control instruction is not limited.

[0064] The scene determination module 260 may be disposed inside the bracket main body 210, such as in the second main body, for determining the recording scene. The scene determination module 260 is electrically connected to the microphone module 220 and can synchronize the determined recording scene to the microphone module 220, so that the microphone module 220 can determine the pickup mode, and then call the directional microphone array or the omnidirectional microphone array to collect clear and lossless voice signals.

[0065] The scene determination module 260 is built-in with at least one sensor unit, and the sensor unit may be one or more of a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer.

[0066] According to the sensor unit, when the bracket main body is in the first posture, the recording scene is determined to be a live recording scene, and the first posture means that the bracket main body and the back panel of the mobile phone form a first angle, and the first angle is an angle that can support the mobile phone; and according to the sensor unit, when the bracket main body is in the second posture, the recording scene is determined to be a call recording scene, and the second posture means that the bracket main body and the back panel form a second angle, and the bracket main body cannot support the mobile phone at the second angle.

[0067] The way for the scenario determination module 260 to determine the recording scenario can be as follows: Based on the triaxial accelerometer, determine the first inclination angle of the bracket body, where the first inclination angle is the inclination angle between the main body extension direction of the bracket body and the gravity direction; based on the triaxial gyroscope, determine the angular pulse state of the bracket body, and the angular pulse state characterizes the position change state of the bracket body; based on the triaxial magnetometer, determine the magnetic field state of the bracket body along the target axis direction, and the magnetic field state characterizes the position change state of the bracket body; if the first inclination angle is less than the inclination angle threshold, the angular pulse state has a sudden increase, and the magnetic field state has a sudden increase, then determine that the bracket body is in the second posture.

[0068] Wherein, when the mobile phone bracket is installed on the back panel of the mobile phone, place the mobile phone perpendicular to the ground. The X-axis is the axis parallel to the ground and perpendicular to the Y-axis, the Y-axis is the axis parallel to the ground and pointing away from the mobile phone from the mobile phone bracket, and the Z-axis is the axis perpendicular to the ground.

[0069] The triaxial accelerometer can measure the acceleration of the bracket body on the X, Y, and Z axes. The first inclination angle can be , where is the acceleration of the bracket body on the X-axis, is the acceleration of the bracket body on the Y-axis, is the acceleration of the bracket body on the Z-axis.

[0070] If the first inclination angle is less than the inclination angle threshold, it proves that the bracket body is probably in the second posture. The inclination angle threshold can be 0 or other values, which are not limited here.

[0071] The angular pulse state refers to the spatial rotation dynamic change of the bracket body detected by the triaxial gyroscope. When the bracket sways or moves, a significant angular pulse sudden increase will occur on a specific axis. If the angular pulse state shows a sudden increase, this indicates that the bracket body has experienced obvious movement or sway. Considering that the user may hold the mobile phone and move slightly during a call, this sudden increase in this case often means that the user is using the mobile phone while moving, further supporting the determination of the recording scenario as a call recording. At this time, the bracket body is probably in the second posture.

[0072] The magnetic field state is the change of the surrounding environment magnetic field along the target axis measured by the triaxial magnetometer. When the bracket body approaches the back panel of the mobile phone, due to the influence of the internal components of the mobile phone, the magnetic field will change. If it is detected that the magnetic field state has changed, this may indicate that the bracket body has moved to a position close to the back panel of the mobile phone, usually an operation when the user is about to start a call. This position change prompts us that the user may be about to or is in a call, thus helping to confirm that the recording scenario is a call recording. At this time, the bracket body is probably in the second posture.

[0073] If the first three conditions are met simultaneously, the recording scenario is determined to be a call recording scenario. In places such as a meeting venue where fixed-position recording is required, the mobile phone holder should remain in its original position, and in this case, none of the above conditions will be triggered, thus avoiding misjudgment as a call recording.

[0074] Of course, the sensor unit can also be a Hall sensor or an optical sensor, which is not limited here.

[0075] A Hall sensor is a sensor that works based on the Hall effect. It can detect changes in magnetic field strength, thereby sensing the relative position or proximity between objects. The Hall sensor can be used to detect changes in the distance between the holder and the back panel of the mobile phone. When the second body approaches the back panel of the mobile phone, the Hall sensor can sense this change and determine it as the second posture. Conversely, it is determined as the first posture.

[0076] An optical sensor uses the characteristics of light to detect changes in the environment, such as light intensity, color, or the presence of objects. In a mobile phone holder, the optical sensor can be used to monitor changes in the environment around the holder or directly detect the relative position between the holder and the mobile phone. If the light is strong, it means that the mobile phone holder is in the first posture and the second body is exposed to the outside. If the light is weak, it means that the mobile phone holder is in the second posture and the second body coincides with the first body.

[0077] The scenario determination module 260 will synchronize the determined recording scenario to the microphone module 220, and the microphone module 220 determines the pickup mode according to the recording scenario. Specifically, when the recording scenario is a call recording scenario, the directional microphone array set is called according to the directional pickup mode to collect voice signals; or when the recording scenario is a live recording scenario, the omnidirectional microphone array is called according to the omnidirectional pickup mode to collect voice signals.

[0078] When the scenario determination module 260 determines that the current recording scenario is a call recording scenario, the microphone module 220 will switch to the directional pickup mode. In this mode, the scenario determination module 260 will preferentially call the directional microphone array to collect voice signals. The design goal of the directional microphone array is to focus on sounds in a specific direction while minimizing background noise interference from other directions. This mode is particularly suitable for call recording scenarios because during a call, the user usually holds the mobile phone close to the mouth, and the sound source is relatively fixed and single.

[0079] When the scene determination module 260 determines that the current recording scene is a live recording scene, the microphone module 220 will switch to the omnidirectional pickup mode. In this mode, the scene determination module 260 will call the omnidirectional microphone array to collect voice signals. The design goal of the omnidirectional microphone array is to evenly capture sound signals from all directions. This mode is very suitable for scenarios that require comprehensive coverage of sound sources, such as meeting recordings, lecture recordings, or concerts.

[0080] The omnidirectional pickup mode integrates the input signals of multiple microphones to ensure that the sound details in the entire space can be captured. Whether it is the speech of the speaker, the interaction of the audience, or other sound elements in the environment, they can all be completely recorded. In addition, the scene determination module 260 can also combine intelligent noise reduction algorithms to eliminate unnecessary low-frequency noise and retain clear high-frequency human voices and other important audio information.

[0081] The recording module 270 is electrically connected to the microphone module 220 and can record the voice signals collected by the microphone module 220 in the storage unit 280. And when the recording scene is a live recording scene, the same subject identifier is configured for the speech frames belonging to the same pronunciation subject.

[0082] The storage space 280 not only has efficient storage capabilities but also is equipped with an intelligent periodic cleaning function to ensure more orderly and efficient data management. After a set time period, the storage space 280 will automatically clean the stored data, thereby releasing storage resources and providing sufficient space for subsequent signal storage. In addition, after synchronizing the saved voice signals to external devices (such as smartphones, tablets, or computers), these backed-up data can be actively or passively deleted. This design not only ensures the security of the data but also effectively avoids waste of storage space.

[0083] The storage space 280 can also be set in the cloud environment independently of the bracket body 210. By migrating the data to the cloud, users can enjoy a larger storage space and are no longer limited by the capacity of local hardware. The cloud storage solution not only provides higher data security, including multiple backups and encryption technologies, but also allows users to access this data anytime and anywhere, improving the convenience of obtaining voice signals.

[0084] Of course, the storage space 280 can also be configured in a hybrid mode of local and cloud, that is, important data is backed up to the cloud in real time, while daily use depends on local storage to reduce dependence on the network and improve response speed. When long-term archiving is required or local storage space needs to be released, the selected data can be automatically or according to the user's instructions migrated to the cloud and deleted from the local to ensure a continuous and efficient signal storage process.

[0085] The power module 290 is disposed in the bracket main body 210 and can supply power to the scene determination module 260, the microphone module 220, and the recording module 260, ensuring the continuity of signal transmission and the smooth operation of the recording function. Of course, it also powers the rest of the important components.

[0086] It should be noted that the power module 290 fully considers various usage scenarios of users. For example, in the low-power mode, it can prioritize ensuring the power consumption requirements of core functions (such as communication and recording), and preferentially supply power to the scene determination module 260, the microphone module 220, and the recording module 260, ensuring that the most important recording task can be completed even in the case of tight power.

[0087] In some embodiments, it may further include a communication module (not shown in the figure). The communication module can be connected to the mobile phone via Bluetooth or wireless network. In the call recording scenario, the communication module can collect the remote audio signal obtained by the mobile phone, so that the content recorded by the recording module 270 is more complete.

[0088] Figure 3 It is a flowchart of a recording method according to an embodiment of the present disclosure.

[0089] As Figure 3 shown, the recording method M300 at least includes: step S310, based on the scene determination module of the mobile phone bracket, determining the recording scene of the mobile phone, where the mobile phone bracket is the mobile phone bracket in any of the foregoing embodiments; step S320, based on the microphone module of the mobile phone bracket, calling the microphone array adapted to the recording scene to collect voice signals; and step S330, based on the recording module of the mobile phone bracket, recording the voice signals.

[0090] The mobile phone bracket may include a bracket main body, a scene determination module, a microphone module, a recording module, an assembly component, an interface, a control button, a storage unit, and a power module. It should be noted that the mobile phone bracket is the mobile phone bracket in any embodiment of the present disclosure, and the mobile phone is adapted to the mobile phone bracket. The mobile phone bracket can be Figure 1 the mobile phone bracket 100 in Figure 2 or the mobile phone bracket 200 in

[0091] In step S310, according to the sensor unit, when the bracket main body is in the first posture, it is determined that the recording scene is the on-site recording scene, where the first posture means that the bracket main body and the back plate of the mobile phone form a first angle, and the first angle is an angle that can support the mobile phone; and according to the sensor unit, when the bracket main body is in the second posture, it is determined that the recording scene is the call recording scene, where the second posture means that the bracket main body and the back plate form a second angle, and at the second angle, the bracket main body cannot support the mobile phone.

[0092] Specifically, the sensor unit is at least one of a triaxial accelerometer, a triaxial gyroscope, and a triaxial magnetometer. According to the triaxial accelerometer, a first inclination angle of the bracket main body is determined, and the first inclination angle is the inclination angle between the main body extension direction of the bracket main body and the gravity direction; according to the triaxial gyroscope, an angular pulse state of the bracket main body is determined, and the angular pulse state characterizes the position change state of the bracket main body; according to the triaxial magnetometer, a magnetic field state of the bracket main body along the target axis direction is determined, and the magnetic field state characterizes the position change state of the bracket main body; if the first inclination angle is less than the inclination threshold, the angular pulse state has a sudden increase, and the magnetic field state has a sudden increase, then it is determined that the bracket main body is in the second posture.

[0093] In step S320, when the recording scenario is a call recording scenario, the directional microphone array is called to collect the voice signal according to the directional pickup mode; or when the recording scenario is a live recording scenario, the omnidirectional microphone array is called to collect the voice signal according to the omnidirectional pickup mode.

[0094] The recording method of the present disclosure not only solves the problem that some models of mobile phones cannot record, avoids the problem that an external recording device needs to adjust the angle or has a movement limitation, but also adapts to the environmental characteristics of the recording scenario through the selection of the microphone array, improving the recording effect.
