Detailed Description
In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions according to the embodiments of the present application with reference to the accompanying drawings.
With the continuous development of mobile terminals, more and more modes are used for controlling the mobile terminals by users. Currently, when a user performs audio control on a mobile terminal, audio playing is generally controlled by clicking or dragging an audio control identifier on a display interface of the mobile terminal. Alternatively, the audio may be adjusted by a mechanical key provided on the mobile terminal, for example, by a volume adjustment key.
However, when controlling audio playback by clicking or dragging an audio control icon on the display interface of the mobile terminal, the mobile terminal must be maintained in a bright screen state. Therefore, if the user operates the audio playback for a long time, the mobile terminal is left in the bright screen state for a long time, which necessarily increases the power consumption of the mobile terminal. Alternatively, the user may operate the audio played very frequently, resulting in the mobile terminal having to switch between off and on frequently, which may also increase the power consumption of the mobile terminal. In addition, because the number of the mechanical keys that can be set on the mobile terminal is limited, if the audio playing is operated through the mechanical keys that are set on the mobile terminal, the audio playing operation that can be performed by the mobile terminal is also relatively limited, so that too many audio control functions cannot be realized, and moreover, the requirement of the integrated body of the mobile terminal cannot be met by using the mechanical keys, so that the user experience is poor.
The inventor finds that if the audio playing of the mobile terminal can be controlled in a touch mode when the mobile terminal is in a screen-off state, the power consumption of the mobile terminal caused by screen brightness can be avoided, and the mobile terminal can be ensured to have various modes for operating the audio playing.
Therefore, the inventor provides an audio play control method, an audio play control device, a mobile terminal and a storage medium.
Referring to fig. 1, a mobile terminal 100 may include a mobile terminal body 101 and a touch sensor 102 disposed on the terminal body. Wherein the touch sensor 102 may be one or more. The touch sensor 102 may be a capacitive touch sensor, an ultrasonic touch sensor, or an infrared touch sensor. In some embodiments, the touch sensor 102 may be disposed on the rear cover of the terminal body or on the bezel of the terminal body 101.
Referring to fig. 2, the method may include:
in step S110, it is determined whether a touch operation is detected by the touch sensor while the mobile terminal is playing audio.
The mobile terminal may play audio in the background through audio playing software, where the audio playing software may be, for example, a music player, foreign language hearing software, voice assistant software, video playing software that may play audio in the background, and the like. The audio may be music, recordings, broadcasts, etc. While the audio is being played, a touch sensor provided on the mobile terminal detects in real time whether a user has performed a touch operation on the mobile terminal, wherein it is understood that the touch operation refers to an operation of the user touching the mobile terminal with different actions through the finger, such as a click action, a double click action, a long press action, a sliding action, etc. made by the user on the mobile terminal.
Step S120, if touch operation is detected, determining whether the mobile terminal is in a screen off state.
And when the mobile terminal detects the touch operation made by the user, continuously detecting whether the current mobile terminal is in a screen-off state. Alternatively, when the mobile terminal does not detect the touch operation of the user, it may return to step S110 to re-detect whether the touch operation of the user is performed on the mobile terminal. The detection of whether the mobile terminal is in the off-screen state may be determined by detecting the brightness of the mobile terminal, and specifically, when the brightness of the mobile terminal is 0, it may be determined that the mobile terminal is in the off-screen state.
Step S130, if the mobile terminal is in the screen-off state, touch information is generated according to the touch operation, and the audio playing action of the mobile terminal is updated according to the touch information.
When the mobile terminal is detected to be in the screen-off state currently, corresponding touch information is generated according to the touch operation detected by the touch sensor, and then the audio playing action of the mobile terminal can be updated according to the touch information. Specifically, when controlling the audio playing action, a touch may correspond to an audio playing action, for example, the user may pause the playing of the audio through a double click action made on the mobile terminal, may start the playing of the audio through a single click action made on the mobile terminal, may select the progress of the audio playing through a sliding action made on the mobile terminal, and so on. Because the user updates the audio playing action by touching the mobile terminal in the screen-off state, the situation that the power consumption is increased because the user needs to lighten the screen of the mobile terminal when controlling the audio playing can be avoided, and the service time of the mobile terminal under the same endurance can be effectively prolonged. Meanwhile, the screen unlocking step during audio control of the mobile terminal is omitted, so that the control is more convenient and simpler. Moreover, the audio control is performed through touch operation, so that the problem that too many audio control functions cannot be realized due to the fact that the mechanical keys are used for audio control is avoided, the requirement of an integrated body of the mobile terminal can be met, and therefore user experience can be improved.
It can be understood that generating touch information according to a touch operation refers to extracting some action features generated when a user touches a mobile terminal, most of the action features are analog signals, and then converting the analog signals into digital signals that can be identified by a processor of the mobile terminal, i.e. touch information, for example, when the user clicks an area (hereinafter referred to as an induction area) where a touch sensor is arranged on the mobile terminal, the user can obtain features such as a clicking position, a clicking frequency, a clicking force, and the like, and can generate feature values corresponding to the clicking action according to the features, i.e. touch information. For example, when the touch operation of the user is to press any point in the sensing area of the mobile terminal for a long time, the characteristics of the long time, such as the position, the force and the duration of the long time, can be obtained, and the characteristics are converted into corresponding values, namely the touch information corresponding to the long time pressing operation. For example, the user's touch operation is to slide a distance in the sensing area of the mobile terminal, at this time, features such as the sliding distance and the touch force during sliding can be obtained, and these features are converted into corresponding values, that is, the touch information corresponding to the sliding operation.
In some embodiments, the mobile terminal includes a first sensing area, where the first sensing area is a shape area with a border, and may be a long strip area, a round area, or a rectangular area, and optionally, the first sensing area may be located on a back cover or a frame of the mobile terminal, and when the first sensing area is located on the frame, the first sensing area may be disposed along a length direction of the mobile terminal. The touch sensors are disposed in the first sensing area, wherein the number of the touch sensors may be plural, and the plurality of touch sensors may be uniformly distributed on the first sensing area. Referring to fig. 3, in some embodiments, an audio playback control method may include the steps of:
in step S210, it is determined whether a touch operation is detected by the touch sensor while the mobile terminal is playing audio.
Step S220, if touch operation is detected, whether the mobile terminal is in a screen-off state is determined.
In step S230, first touch information on the first sensing area is acquired, the first touch information corresponds to a touch operation acting on the first sensing area, and the first touch information includes a first sliding start point and a first sliding end point.
As an example, the first sensing area corresponds to updating of the audio playing file, and the touch operation made by the user in the first sensing area can control the audio playing file. The mobile terminal detects first touch information on the first sensing area in real time, wherein the first touch information can be touch information corresponding to sliding action, it can be understood that the first touch information and the touch information are the same type of information and can be generated by touch operation, and the generation process of the first touch information is approximately the same as that of the touch information generated according to the touch operation. Specifically, the first touch information may include a first sliding start point and a second sliding end point, and it is understood that the first sliding start point refers to a position where the user first touches the first sensing area when making a sliding motion in the first sensing area, and the first sliding end point refers to a position where the user leaves the first sensing area when making a sliding motion in the first sensing area, or a position where the user is in the first sensing area when stopping the sliding motion.
Step S240, obtaining the corresponding endpoint coordinates of the first sliding endpoint on the first sensing region.
In one embodiment, a two-dimensional plane coordinate system may be established in advance with an arbitrary point on the first sensing region (for example, a center point of the first sensing region) as an origin, and then the coordinate endpoint may be determined according to a position of the first sliding endpoint in the two-dimensional plane coordinate system. In another embodiment, when the first sensing region is in a long strip shape, a one-dimensional linear coordinate system may be established in advance with one end of the first sensing region as an origin, and then the coordinate endpoint may be determined according to a position of the first sliding endpoint in the one-dimensional linear coordinate system.
Step S250, if the end point coordinate is at the first designated position of the first sensing area, updating the audio playing file according to the first touch information.
When the mobile terminal detects that the end point coordinate is at the first designated position, an audio playing file updating action can be correspondingly triggered, wherein the first designated position can be one designated coordinate point or a plurality of designated coordinate points in the first sensing area, and specifically can be designated coordinate points on the boundary of the first area. For example, the first designated position includes a plurality of first designated coordinate points, each coordinate point corresponds to a playing trigger of an audio file, when the terminal point coordinate is consistent with the coordinate of one of the first designated coordinate points, the audio file currently played by the mobile terminal can be switched to the audio file corresponding to the first designated coordinate point for playing, wherein the corresponding relationship between the first designated coordinate point and the audio file can be prestored in the mobile terminal. In the embodiment, the user can switch different audio files to play by making a sliding action in the first sensing area, even if the mobile terminal is in a screen-off state, the mobile terminal can be accurately switched, and the control of the user on audio playing is simplified.
In some embodiments, in which the playing order of the plurality of audio files is preset in the mobile terminal, referring to fig. 4, in step S250, updating the audio playing file according to the first touch information may include the following steps:
step S251, determining a first sliding direction according to the first sliding start point and the first sliding end point.
The mobile terminal can determine the first sliding direction according to the coordinates of the first sliding starting point and the second sliding ending point in the coordinate system of the first sensing area.
In step S252, an audio file arranged before or after the currently played audio file is selected from the plurality of audio files according to the first sliding direction for playing.
The mobile terminal stores different first sliding directions in advance corresponding to the switching directions of different audio files, for example, when the first sensing area is in a long strip shape, one end of the first sensing area is used as the head end, the other end is used as the tail end, if the first sliding direction is set to be the direction towards the tail end of the first sensing area, the first sliding direction corresponds to the action of selecting the audio files arranged behind the currently played audio file for playing, when the user slides towards the tail end of the first sensing area, the mobile terminal switches to the audio files arranged behind the currently played audio file for playing, and when the user slides towards the head end of the first sensing area, the mobile terminal switches to the audio files arranged behind the currently played audio file for playing. In the embodiment, the user can quickly realize the switching of the audio playing file only by sliding, and the mobile terminal can accurately switch even in the screen-off state, thereby being convenient for the user to control the audio playing.
Referring to fig. 5, in some embodiments, an audio playback control method may include the steps of:
in step S310, it is determined whether a touch operation is detected by the touch sensor while the mobile terminal is playing audio.
Step S320, if touch operation is detected, determining whether the mobile terminal is in a screen off state.
In step S330, first touch information on the first sensing area is acquired, the first touch information corresponds to a touch operation acting on the first sensing area, and the first touch information includes a first sliding start point and a first sliding end point.
Step S340, obtaining the corresponding endpoint coordinates of the first sliding endpoint on the first sensing region.
In step S350, if the endpoint coordinate is at the first designated position of the first sensing area, the audio playing file is updated according to the first touch information.
In some embodiments, the first designated location may be a plurality of first designated coordinate points located on a boundary of the first sensing region. If the terminal point coordinate of the first sliding terminal point is consistent with the coordinate of the first designated coordinate point on the boundary of the first sensing area, it can be indicated that the finger part slides to or slides out of the boundary of the first sensing area when the user slides in the first sensing area, at this time, the audio control action of the mobile terminal can update the audio playing file, and when the finger part of the user slides to or slides out of the boundary of the first sensing area, the user switches to the corresponding audio file according to the sliding direction to play. The audio playing file can be switched by detecting whether the finger of the user slides out of the boundary of the first sensing area, so that the switching accuracy can be ensured.
In step S360, if the end point coordinate is at the second designated position of the first sensing area, the first sliding distance and the first sliding direction are determined according to the first sliding start point and the first sliding end point.
In some embodiments, the second designated location may be a plurality of second designated coordinate points located within the boundary of the first sensing region, and it is understood that the first designated coordinate point and the second designated coordinate point are in the same coordinate system, and the coordinate system may be established with the center point of the first sensing region as the origin. If the end point coordinate of the first sliding end point is consistent with the coordinate of the second designated coordinate point in the boundary of the first sensing area, it can be indicated that the finger part is always positioned in the boundary of the first sensing area when the user slides in the first sensing area, and at this time, the audio control action of the mobile terminal can update the audio playing progress.
Step S370, determining the increasing direction of the audio playing progress according to the first sliding direction.
Among them, it is understood that the increasing direction of the audio playing progress includes a reverse direction and a forward direction. When the audio playing progress increases towards the reversing direction, reversing the audio playing progress to the front of the current playing progress; when the audio playing progress increases forward, the audio playing progress advances to the back of the current playing progress. For example, the current audio playing progress is 2 minutes and 20 seconds, when the audio playing progress increases in the backward direction, the playing progress can be switched to a certain time between the beginning of audio and 2 minutes and 20 seconds, and when the audio playing progress increases in the forward direction, the playing progress can be switched to a certain time between 2 minutes and 20 seconds and the end of audio.
In step S380, an increasing amount of the audio playing progress in the increasing direction is determined according to the first sliding distance.
Step S390, the audio playing progress is updated according to the increasing direction and increasing amount of the audio playing progress.
As an example, when the first sensing area is in a long strip shape and the first sensing area is disposed on the mobile terminal along the width direction of the mobile terminal, referring to fig. 6, if the user slides the finger portion on the first sensing area toward the head end of the first sensing area, the audio playing progress may be increased toward the reversing direction, and the increase amount of the progress reversing is proportional to the first sliding distance. If the user slides the finger part on the first sensing area towards the tail end of the first sensing area, the audio playing progress can be increased towards the advancing direction, and the increasing amount of the progress is proportional to the first sliding distance. In this embodiment, the user can realize control of two audio play actions only by making a touch operation on one sensing area, so that audio control is more flexible and faster.
In other embodiments, the mobile terminal includes a second sensing area, where the second sensing area may be an elongated area, alternatively, the second sensing area may be located on a rear cover of the mobile terminal or on a frame, and when the second sensing area is located on the frame, the second sensing area may be disposed along a length direction of the mobile terminal. The touch sensors are disposed in the second sensing area, wherein the number of the touch sensors may be plural, and the plurality of touch sensors may be uniformly distributed on the second sensing area.
Referring to fig. 7, in some embodiments, an audio playback control method may include the steps of:
in step S410, it is determined whether a touch operation is detected by the touch sensor while the mobile terminal is playing audio.
Step S420, if touch operation is detected, determining whether the mobile terminal is in a screen off state.
In step S430, second touch information on the second sensing area is acquired, where the second touch information corresponds to a touch operation performed on the second sensing area, and the second touch information includes a second sliding start point and a second sliding end point.
The second sensing region may be substantially the same as the first sensing region, and the second touch information may be substantially the same as the first touch information.
Step S440, determining a second sliding distance and a second sliding direction according to the second sliding start point and the second sliding end point.
Step S450, determining the adjusting direction of the audio playing volume according to the second sliding direction. It will be appreciated that the direction of adjustment of the audio play volume includes either a volume increase or a volume decrease.
Step S460, determining the adjusting quantity of the audio playing volume in the adjusting direction according to the second sliding distance. It is understood that the adjustment amount of the audio play volume in the adjustment direction refers to an increase amount of the volume or a decrease amount of the volume.
Step S470, the audio playing volume is updated according to the adjusting direction and the adjusting amount of the audio playing volume.
As an example, referring to fig. 8, when the second sensing area is elongated and is disposed on the rear cover or the frame of the mobile terminal along the length direction of the mobile terminal, one section of the second sensing area is taken as the top end, and the other section is taken as the low end. When the finger part for the user slides towards the top end of the second sensing area, namely the second sliding direction faces towards the top end of the second sensing area, the volume is increased; when the finger part slides towards the bottom end of the second sensing area, the volume is reduced, the volume increment or the volume reduction is proportional to the sliding distance, and the sliding distance of the finger part on the second sensing area is the second sliding distance. In the embodiment, the user can quickly adjust the audio playing volume only by sliding, and even if the mobile terminal is in a screen-off state, the mobile terminal can also be accurately adjusted, so that the control of the user on the audio playing is facilitated.
In some embodiments, referring to fig. 1 again, the first sensing area 103 and the second sensing area 104 are both disposed on the rear cover of the terminal body 101, the first sensing area 103 and the second sensing area 104 are both elongated, and the first sensing area 103 and the second sensing area 104 are perpendicular to each other. Alternatively, the first sensing region 103 and the second sensing region 104 may or may not intersect.
In some embodiments, in the first sensing area 103 and the second sensing area 104 which are elongated, a series of capacitive sensors may be placed adjacently, so that an increasing or decreasing of input may be realized, and further, a sliding detection process may be realized, and since the first sensing area 103 and the second sensing area 104 are perpendicular to each other, the capacitive sensors are arranged in a horizontal-vertical order, so that a sliding operation of the two-dimensional sensor may be realized. When the finger touch is detected, the detection of the sliding is realized by analyzing the position of the sensor touched by the finger. This sensor placement is referred to as a slider. When a user touches a certain slide bar segment, the adjacent slide bar segments are activated, and the corresponding control integrated circuits (Integrated Circuit, IC) of the mobile terminal 100 calculate the geometric center position of the finger touch by processing the original counts of the touched slide bar segment and the adjacent slide bar segments, and the digital count value of each sensor is used for calculating the center position, so that the resolution of the center position can be effectively improved, and the resolution is far higher than the number of the slide bar segments. For example, the inclusion of five slides may resolve at least 100 physical locations of the finger. If the detection data of the central position pressed by the finger is larger than the geometric edge position touched by the finger, after the position of the finger is detected, the control integrated circuit records the position, when the finger moves, the received data can change continuously along with the movement of the finger, so that the update of the central position is judged, the size of the displacement of the finger can be judged by recording the central position in real time, the sliding detection is realized, and the control integrated circuit can calculate the sliding direction and the sliding displacement according to the position information.

In step S523, if the touch strength is greater than or equal to the touch strength threshold and the sliding distance is greater than or equal to the sliding distance threshold, it is determined that the touch operation is valid. In the present embodiment, it is possible to accurately determine whether a touch operation is effective by simultaneously detecting the touch force and the sliding distance.

In this embodiment, whether the touch operation is effective is determined by determining whether the touch force is greater than or equal to the touch force threshold, and determining that the sliding distance is greater than or equal to the sliding distance threshold when the touch force is greater than or equal to the touch force threshold.
In step S530, if the touch operation is valid, it is determined whether the mobile terminal is in the off-screen state. Alternatively, if the touch operation is detected to be invalid, the process may return to step S210 to re-detect the touch operation, so as to ensure that the mobile terminal detects whether there is a touch operation in real time.
Step S540, if the mobile terminal is in the screen-off state, touch information is generated according to the touch operation, and the audio playing action of the mobile terminal is updated according to the touch information.
In other embodiments, referring to fig. 12, an audio playing control method may include:

Step S640, determining whether there is an audio play action associated with the touch information in the mobile terminal.
Specifically, the audio play action associated with the touch information may be stored in the mobile terminal in advance, for example, a sliding distance in the touch information may be associated with an adjustment amount of the audio play volume, for example, a sliding direction in the touch information may be associated with a switching direction of the audio play file. By detecting whether the audio playing action associated with the touch information exists in the mobile terminal, the user can be further ensured to accurately perform audio playing control.
Step S650, if yes, updating the audio playing action of the mobile terminal according to the touch information; if not, returning to the step of determining whether the touch operation is detected by the touch sensor.
In some embodiments, if the audio playing action associated with the touch information does not exist in the mobile terminal, a reminding message for reminding the user that the current touch operation is an invalid operation may be displayed on the mobile terminal. In other embodiments, if there is no audio action associated with the touch information, the mobile terminal may send information for indicating to the user that the current touch operation is associated with the audio play action, for example, the mobile terminal reminds the user whether to associate the current touch operation with the audio play action, if so, a plurality of audio play actions are listed for the user to select, and after the selection, when the user makes the touch operation again, the mobile terminal performs the audio play action corresponding to the touch operation, so as to implement the user-defined setting of the touch operation.
In some embodiments, when pressure detection is performed using a capacitive touch sensor, finger pressure detection is to detect a change in substrate capacitance using self-capacitance sensing to determine whether there is a finger press. As shown in fig. 13 and 14, a General-purpose input/output (GPIO) pin is connected to the sensor substrate, i.e., to the printed circuit board, via traces and vias, and separated from other sensors and their traces around the grid of sensing layers, which may be sensor pads, fig. 13 shows a state without finger pressing, and parasitic capacitance C exists between the substrate and the grid, which is a minute value that is fixed without changing the surrounding environment. Fig. 14 shows a state in which there is a finger press, the conductive property and the large mass of the human body constitute a grounded ground layer (parallel to the sensor pad), and this operation constitutes one parallel plate capacitor. The capacitance between the sensor pad and the finger can be calculated by the following formula:
Wherein ε0=air dielectric constant; epsilonr = relative permittivity of the cover layer; a = contact area of the finger and sensor pad cover, cover layer; d = cover layer thickness; c (C) F Is the finger capacitance. Due to parasitic capacitance C P And finger capacitance C F Both can represent the capacitance of the sensor pin and ground, so both are identical in nature.
Thus, when a finger contacts the sensor, the sensor total capacitance C S Equal to C P And C F And (3) summing.
Referring to fig. 15, each GPIO of the capacitance control IC has a switched capacitor circuit for converting the sensor capacitance value to an equivalent current. The analog converter (Analog Multiplexer) then selects one of the current signals and sends the signal To the current-To-digital converter (current-To-Digital Converter). The principle of operation of the current-to-digital converter is similar to that of a Delta Sigma ADC. The output count of the current-to-digital converter is a digital value proportional to the self-capacitance between the individual electrodes. Thus, the capacitance sensor control IC may convert Cs into a corresponding digital count value in real time, and identify whether a finger touch is present by analyzing the increment of the digital count value, as shown in fig. 16.
Specifically, in this embodiment, the mobile phone battery cover may be in the form of a key, the pad of the key is implemented by a flexible circuit board (Flexible Printed Circuit, FPC) coil, the coil is attached to the back of the battery cover by double sided tape, and the coil is connected to the GPIO of the control IC by an FPC flat cable. Inside the IC, cs is first charged and discharged by driving the GPIO, the capacitance value of Cs is converted into an analog voltage waveform, and then the voltage waveform is converted into a digital signal by the sigma-delta ADC and recorded as a digital count value corresponding to Cs.
In some embodiments, when the sliding detection is performed, a series of capacitive sensors are adjacently placed based on a pressing principle, so that the input increment or decrement can be realized, and further, the sliding detection process is realized, and if the capacitive sensors are arranged in sequence in a horizontal-vertical manner, the sliding operation of the two-dimensional sensor can be realized. As shown in fig. 17, the double V-shaped pattern areas respectively represent pads of six sensors, and when a finger touch is detected, detection sliding is realized by analyzing the sensor position of the finger touch, and such a sensor placement form is technically called a slider. Touching a certain slide bar section activates adjacent slide bar sections, the control IC calculates the geometric center position of finger touch by processing the original counts of the touched slide bar section and the adjacent slide bar sections, and the digital count value of each sensor is used for calculating the center position, so that the resolution of the center position can be effectively improved, and the resolution is far higher than the number of the slide bar sections. For example, the inclusion of five slides may resolve at least 100 physical locations of the finger.
When the central position detection data pressed by the finger is larger than the edge position, the IC records the position after the finger position is detected, and when the finger moves, the received data can change continuously along with the movement of the finger, so that the update of the central position is judged, the size of the finger displacement can be judged by recording the central position in real time, the sliding detection is realized, and the control IC can calculate the sliding direction and the sliding displacement according to the position information.
The application of the sliding detection on the mobile phone can be as shown in fig. 18, the battery cover at the back of the mobile phone is attached to the two sensors in the horizontal direction and the vertical direction, each slide bar adopts 6 capacitance sensors, and the total number of the capacitance sensors is 12, so that the two-dimensional sliding detection is realized. The sensor is connected with the control IC through the FPC, and the control IC is welded at the main board end and communicated with the AP through the IIC. In practical use, the number of sensors required may be 3 or more to ensure the size and accuracy of the sliding touch area.
