A control method of a wearable device, a wearable device and a control method thereof

[0001] Priority information: This application claims priority to the Chinese patent application with the application number 2024108894082, which was filed on July 4, 2024. TECHNICAL FIELD

[0002] The present application relates to the technical field of control of electronic devices, and in particular to a control method of a wearable device, a wearable device and a control method thereof. BACKGROUND

[0003] In the use process of the earphone, the user needs to control the earphone, for example, to perform operations such as turning on / off, adjusting the volume, or changing songs. In order to improve the waterproof and dustproof effect, some earphones replace the traditional mechanical button with a capacitive button, for example, a capacitive sensor is arranged on the inner side of the shell to sense the change of the capacitive signal; when the user touches the touch area of the capacitive button, the electric field of the touch area will be affected, causing the change of the capacitance, and the corresponding control signal is generated through the change of the capacitance, so that the earphone performs operations such as volume adjustment or song changing.

[0004] However, the capacitive button is difficult to be used in a water environment, when the outer surface of the touch area has water, the capacitance of the capacitive button will be affected, which may cause the earphone to sense the wrong signal, and further cause misoperation, for example, uncontrolled volume increase or decrease or continuous operation of the earphone, so that the earphone cannot be normally used. In addition, when the outer surface of the touch area has water, the capacitive button will be difficult to identify the control of the finger, causing the touch function to fail or be insensitive. Therefore, when the earphone is used in an environment that needs to contact water, such as a lot of sweat, rainy days or swimming, it is difficult to reliably control the earphone.

[0005] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. SUMMARY

[0078] In order to make the above objectives, features and advantages of the present application more clear and comprehensible, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the purpose of description, only the parts related to the present application are shown in the drawings, rather than all the structures. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0079] The terms "comprising" and "having" and any variations thereof in the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0080] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily independent or alternative embodiments to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0081] The present application proposes a control method of a wearable device, as shown in FIG. 1, the wearable device includes a touch panel 100 and a capacitive sensing module 26 and a pressure sensing module 25 arranged correspondingly to the touch panel 100, the capacitive sensing module 26 and the pressure sensing module 25 are respectively used for detecting a capacitive signal and a pressure signal of the touch panel 100.

[0082] The touch panel 100 is part of a housing assembly 1 of the wearable device, the capacitive sensing module 26 and the pressure sensing module 25 are arranged in the part corresponding to the touch panel 100 inside the housing assembly 1, the capacitive sensing module 26 includes a capacitive sensor, the pressure sensing module 25 includes a pressure sensor, the pressure sensor can be a micro-electromechanical pressure sensor, a capacitive pressure sensor, an inductive pressure sensor or a piezoelectric pressure sensor. The capacitive sensing module 26 and the pressure sensing module 25 are stacked and arranged on the inner surface 1000 of the touch panel 100, and are arranged along the thickness direction Z of the touch panel 100. Preferably, the capacitive sensing module 26 is attached to the inner surface 1000 of the touch panel 100, and the pressure sensing module 25 is located inside the capacitive sensing module 26.

[0083] When the finger touches the touchpad 100, the electric field distribution and the capacitance between the capacitive sensing electrodes will change, so that the capacitive sensing module 26 can detect the change in capacitance, at the same time, the pressure of the finger on the touchpad 100 will cause the pressure sensing module 25 to deform, and then the pressure sensing module 25 detects the change in pressure. Different operation gestures of the touchpad 100 will cause different changes in the capacitive signal and the pressure signal, and the control circuit board 3 inside the wearable device can generate corresponding control signals according to the capacitive signal and the pressure signal, so that the user can control the wearable device to perform different actions by different operations on the touchpad 100, such as volume adjustment, pausing / continuing playing, or waking up the voice assistant, etc.

[0084] The part of the outer surface of the touchpad 100 corresponding to the touch sensing assembly 2 forms a touch area 101, and the position of the touch area 101 is schematically shown in dashed lines in FIG. 2 and FIG. 9. When the touch area 101 is operated, the operation of the human hand can usually be more reliably recognized.

[0085] As shown in FIG. 3, the control method of the wearable device includes the following steps:

[0086] S1. receiving a capacitive signal of the capacitive sensing module 26 and a pressure signal of the pressure sensing module 25;

[0087] S2. switching the wearable device to a touch water control mode or a non-touch water control mode according to the capacitive signal;

[0088] In the non-touch water control mode, a corresponding control signal is generated according to the change in the capacitive signal;

[0089] In the touch water control mode, a corresponding control signal is generated according to the change in the pressure signal.

[0090] In step S2, it can be determined whether there is water on the surface of the touchpad 100 according to the capacitive signal. It can be understood that the dielectric constant of water 78.5 is much higher than that of air 1, and the influence on the electric field and the capacitance is different, so when there is water (such as swimming or diving or rain) on the surface of the touchpad 100 and no water (such as in the air), the capacitance is different, and then it can be identified whether there is water on the surface of the touchpad 100, and the two capacitive range intervals are preset, which can be corresponding to whether there is water on the surface of the touchpad 100 or not, that is, it can be used to judge the use environment of the wearable device.

[0091] In the non-water-touching control mode, when the surface of the touch plate 100 has no water, the capacitance sensing is more sensitive, and the corresponding control signal is generated through the change of the capacitance signal, so that the wearable device can be conveniently controlled. When the surface of the touch plate 100 has water, the capacitance sensing module 26 is not sensitive to the change of the capacitance of the touch plate 100, and even the capacitance signal may be incorrectly sensed, causing the wearable device to malfunction. Therefore, it is switched to the water-touching control mode, and the corresponding control signal is generated through the pressure signal, which not only can control the wearable device, but also can prevent the risk of malfunction caused by using capacitance sensing to control. In this way, by setting the water-touching control mode and the non-water-touching control mode, the advantages of capacitance sensing and pressure sensing can be fully utilized, and the reliability of the user's control of the wearable device in different environments can be ensured.

[0092] In step S1, the capacitance signal and the pressure signal are detected by the capacitance sensing module 26 and the pressure sensing module 25 respectively, and the control circuit board 3 receives the electrical signals transmitted by the capacitance sensing module 26 and the pressure sensing module 25. In step S2, the control circuit board 3 switches the wearable device to the water-touching control mode or the non-water-touching control mode according to the capacitance signal.

[0093] In some embodiments, as shown in FIGS. 4 and 5, the capacitance sensing module 26 includes at least two capacitance recognition areas 260 arranged in the same direction, and the pressure sensing module 25 includes at least two pressure sensing recognition areas 250 arranged in the same direction. Each capacitance recognition area 260 is electrically connected to the control circuit board 3 and can independently generate a capacitance signal and transmit it to the control circuit board 3. Each pressure sensing recognition area 250 is electrically connected to the control circuit board 3 and can independently generate a pressure signal and transmit it to the control circuit board 3.

[0094] The arrangement direction of the capacitance recognition area 260 and the arrangement direction of the pressure sensing recognition area 250 are the same, and when the touch plate 100 is operated, the capacitance recognition area 260 and the pressure sensing recognition area 250 can simultaneously sense the change of the capacitance signal and the pressure signal. Alternatively, in the two modes of the water-touching control mode and the non-water-touching control mode, the same operation of the touch plate 100 produces the same type of control signal, so as to facilitate the control of the wearable device.

[0095] In some embodiments, in step S2, the step of switching the wearable device to the water-touching control mode or the non-water-touching control mode according to the capacitance signal includes:

[0096] The wearable device can automatically switch the control mode according to the capacitance signal, and is more convenient to use. For example, when the wearable device is worn while swimming, the water contact control mode can be automatically switched, and the wearable device can be controlled in water.

[0097] Generally, when the part corresponding to the capacitance recognition area 260 of the touchpad 100 has water, the capacitance will rise to the maximum value of the capacitance range, and therefore the first capacitance interval can be set to the maximum value of the capacitance range or a certain percentage of the maximum value, for example, 90% to 100% of the maximum value of the capacitance range as the first capacitance interval, as long as it is not in the first capacitance interval, that is, in the second capacitance interval.

[0098] By setting at least two capacitance recognition areas 260 and pressure recognition areas 250, the pressure module 25 and the capacitance sensing module 26 can not only recognize the click operation, but also recognize the sliding operation. When the click operation is performed on the surface of the touchpad 100, the capacitance recognition area 260 and the pressure recognition area 250 corresponding to the region will produce single or multiple capacitance and voltage changes, and when the sliding operation is performed on the surface of the touchpad 100, the capacitance signals of different capacitance recognition areas 260 will sequentially change and the pressure signals of different pressure recognition areas 250 will sequentially change. According to the form of the change of the capacitance signal or the change of the pressure signal, the sliding direction of the finger on the touchpad 100 or the number of clicks can be recognized, and different control signals can be generated according to different operation modes, and the control mode is more rich.

[0099] Since the capacitance recognition area 260 is easily affected by the external environment, the number thereof is preferably greater than or equal to 3 to reduce misjudgment. In the embodiment shown in FIG. 4, the touchpad 100 includes four capacitance recognition areas 260, when the finger does not touch the touchpad 100, the capacitance values sensed by the four capacitance recognition areas 260 are basically the same and do not change, when the finger slides on the surface of the touchpad 100, the capacitance signal of the capacitance recognition area 260 touched by the finger will change, and the change of the capacitance signal has a sequence, according to the sequence of the change of the capacitance signal generated by the capacitance recognition area 260, the sliding direction of the finger can be determined.

[0100] In some embodiments, in step S2, the change of the capacitance signal includes the sequence of the capacitance recognition area 260 generating the change of the capacitance signal, to identify that the operation is a sliding operation, and at the same time identify the direction of the sliding.

[0101] For the convenience of description, four capacitive identification areas 260 are shown in FIG. 4, which are area No. 1, area No. 2, area No. 3 and area No. 4. When the capacitive signal changes of the area No. 1, area No. 2, area No. 3 and area No. 4 occur in time sequence, it is determined that the finger moves to the right. Of course, because the finger can not contact all the areas, for example, when the sensor detects the capacitive changes of the area No. 1, area No. 2 and area No. 3 in time sequence, or the sensor detects the capacitive changes of the area No. 2, area No. 3 and area No. 4 in time sequence, it is also determined that the finger moves to the right. Conversely, when the sensor detects the capacitive changes of the area No. 4, area No. 3, area No. 2 and area No. 1, or the capacitive changes of the area No. 4, area No. 3, area No. 2, or the capacitive changes of the area No. 3, area No. 2 and area No. 1 in time sequence, it is determined that the finger moves to the left. According to the direction of the finger sliding, corresponding control signals can be generated, for example, control signals for adjusting the volume to increase or decrease. The rightward sliding can be set to increase the volume, and the leftward sliding can be set to decrease the volume.

[0102] It can be understood that the sliding operation and direction of the finger can be determined when the capacitive changes of any two adjacent capacitive identification areas 260 occur in time sequence. The more the capacitive identification areas 260 whose capacitive changes occur in time sequence, the more accurate the detection of the finger sliding. Alternatively, when the capacitive signals of three or more capacitive identification areas 260 change in time sequence, control instructions are generated for the capacitive signals to prevent misjudgment and improve the reliability and accuracy of the operation.

[0103] Further alternatively, the change of the capacitive signal also includes a time interval for generating the capacitive signal change. It can be understood that when the finger slides across the capacitive identification areas 260, the capacitive identification areas 260 that are slid across will generate capacitive signal changes in time sequence. The shorter the time interval for generating the capacitive signal change, the faster the sliding speed. Conversely, the longer the time interval, the slower the sliding speed. Thus, different control signals can be generated, for example, when the time interval is smaller, the volume increase or decrease speed can be faster, and vice versa. The time interval is larger, the volume increase or decrease speed can be slower. That is, the faster the sliding, the faster the volume change, and the slower the sliding, the slower the volume change.

[0104] The method of determining whether the operation gesture is a sliding operation and determining the sliding direction by the pressure signal is similar to the method of determining by the capacitance signal. Specifically, in the step S2, the change of the pressure signal includes the order of at least two adjacent pressure sensing recognition areas 250 that produce the change of the pressure signal. According to the order of the pressure sensing recognition areas 250 that produce the change of the pressure signal, it can be determined in which direction the sliding is performed, and further a corresponding control signal is generated. Further optionally, the change of the pressure signal includes the time interval of the change of the pressure signal, so as to determine the speed of the sliding, and different control signals are generated according to the speed, for example, the speed of increasing or decreasing the volume.

[0105] The pressure sensing is less likely to cause misoperation than the capacitance sensing, and therefore, two pressure sensing recognition areas 250 can be set to reliably determine the direction of the sliding touch. Of course, three or more pressure sensing recognition areas 250 can also be set. Three pressure sensing recognition areas 250 are shown in FIG. 5.

[0106] In some embodiments, the change of the capacitance signal includes the number and duration of the change of the capacitance signal produced by any of the capacitance recognition areas 260 within a preset time period.

[0107] When the finger performs a clicking operation on the touchpad 100, one or more capacitance recognition areas 260 will simultaneously produce a change of the capacitance, which is obviously different from the change of the capacitance signal produced by the sliding operation, and thus it can be determined that the finger performs a clicking operation on the touchpad 100. According to the number and duration of the change of the capacitance signal produced by any of the capacitance recognition areas 260 within a preset time period, the operation mode of the finger can be identified, for example, it can be determined whether it is a single click, a double click, or a long press, and so on. As an exemplary embodiment, a single change of the capacitance signal produced at the same position is a single click, two changes of the capacitance signal are a double click, and the capacitance signal changes at the same position and then remains for a certain time before returning, which is a long press (the duration of the capacitance signal of the single click is less than that of the long press). Different control signals can be generated for different operation modes. Optionally, the control signal corresponding to the double click operation is to wake up the voice assistant.

[0108] Optionally, before the identification of the click operation, it can be judged whether the change of the capacitance signal is generated by two adjacent capacitance recognition areas 260 in turn (i.e. whether it is a sliding touch operation), if not, the identification of the click operation is performed, i.e. the number of times and the duration of the change of the capacitance signal generated by any of the capacitance recognition areas 260 in a preset time period are detected, and the corresponding control signal is generated accordingly, which can prevent the sliding operation from being misjudged as a click operation. Specifically, in step S2, the generation of the corresponding control signal according to the change of the capacitance signal comprises: judging whether the change of the capacitance signal is generated by two adjacent capacitance recognition areas 260 in turn, if yes, generating the corresponding control signal according to the order of the at least two adjacent capacitance recognition areas 260 generating the change of the capacitance signal; and if not, generating the corresponding control signal according to the number of times and the duration of the change of the capacitance signal generated by any of the capacitance recognition areas 260 in a preset time period.

[0109] Further, different control signals can also be generated in combination with the position where the change of the capacitance signal is generated, for example, the double-click operation on the No. 1 area and the double-click operation on the No. 4 area can generate different control signals. At this time, the change of the capacitance signal also includes the position of the capacitance recognition area 260 where the change of the capacitance signal is generated.

[0110] The method of judging whether the operation gesture is a sliding operation and judging the sliding direction through the pressure signal is similar to the method of judging through the capacitance signal. Specifically, in step S2, the change of the pressure signal comprises the number of times and the duration of the change of the pressure signal generated by any of the pressure sensing recognition areas 250 in a preset time period. According to the number of times and the duration of the change of the pressure signal, it can be identified whether the operation performed is a single click, a double click or a long press, etc., and the corresponding control signal is generated. As an example, a single change of the pressure signal generated at the same position is a single click, two changes of the pressure signal at the same position are a double click, and the pressure signal changes at the same position and remains for a certain period of time before returning to a long press (the duration of the pressure signal of a single click is less than that of a long press).

[0111] Further, different control signals can also be generated in combination with the position where the change of the pressure signal is generated, for example, the double-click operation on the No. 1 area and the double-click operation on the No. 4 area can generate different control signals. At this time, the change of the pressure signal also includes the position of the pressure sensing recognition area 250 where the change of the pressure signal is generated.

[0112] Optionally, before the identification of the click operation, it can be judged whether the pressure signal changes are generated by two adjacent pressure sensing areas 250 in turn (i.e. whether it is a sliding touch operation), if not, the identification of the click operation is performed, that is, the number and duration of the pressure signal changes generated by any of the pressure sensing areas 250 in a predetermined time period are detected, and the corresponding control signal is generated accordingly, which can prevent the sliding operation from being misjudged as a click operation. Specifically, in step S2, the corresponding control signal is generated according to the change of the pressure signal, which includes: judging whether the pressure signal changes are generated by two adjacent pressure sensing areas 250 in turn, if yes, the corresponding control instruction is generated according to the order of the at least two adjacent pressure sensing areas 250 generating the pressure signal changes, if not, the corresponding control instruction is generated according to the number and duration of the pressure signal changes generated by any of the pressure sensing areas 250 in a predetermined time period.

[0113] As a feasible embodiment, in step S2, in the non-water touch control mode, the corresponding control signal is generated according to the change of the capacitance signal, which includes: judging whether the change value of the pressure signal generated with the change of the capacitance signal is greater than a first pressure signal threshold, if greater than the first pressure signal threshold, the corresponding control signal is generated according to the change of the capacitance signal. The pressure signal threshold corresponds to a certain pressure threshold, that is, in the non-water touch control mode, only when the pressure change of the touch panel 100 is greater than a certain pressure, the control signal corresponding to the change of the capacitance signal is generated.

[0114] It can be understood that when the external environment does not change, the capacitance signal and the pressure signal are usually stable at a certain value, when the external environment changes, for example, when the finger touches or the water flow impacts, the capacitance signal and the pressure signal will change, and the difference between the changed signal value and the signal value when stable is the change value of the capacitance signal or the pressure signal. The signal value can be obtained by means in the prior art, for example, the peak value of the signal is taken as the signal value or a certain proportion of the peak value is taken as the signal value.

[0115] Since the capacitance sensing is relatively sensitive, it is easy to be triggered by mistake when the external foreign matter contacts the touch panel 100, for example, when the hair sweeps across the touch panel 100, the control signal may be generated by mistake according to the change of the capacitance signal, which causes the wearable device to malfunction. By setting the control signal to be generated according to the capacitance signal only when the change value of the pressure signal is greater than the first pressure signal threshold, the false triggering can be effectively prevented, for example, when the hair sweeps across the touch panel 100, although the capacitance signal changes, the change intensity of the pressure signal does not meet the requirement, therefore, no control signal will be generated. Optionally, the first pressure signal threshold is greater than or equal to 10g, to reliably prevent false triggering.

[0116] As a feasible embodiment, in the step S2, the step of generating a corresponding control signal according to the change of the pressure signal in the water-touching control mode comprises: judging whether the change value of the pressure signal is greater than a second pressure signal threshold value, and generating a corresponding control signal according to the change of the pressure signal if the change value of the pressure signal is greater than the second pressure signal threshold value.

[0117] In the swimming or other situations, there may be a water flow impacting the touchpad 100, causing the pressure module 25 to generate a pressure signal change, thus, the water flow impact may cause a misoperation. By setting the second pressure signal threshold value, even if the water flow impacts the touchpad 100, as long as the second pressure signal threshold value is not exceeded, no control signal will be generated, thus, the misoperation can be effectively prevented.

[0118] The second pressure signal threshold value is greater than the first pressure signal threshold value, and optionally, the second pressure signal threshold value is any value in 30-100g, so as to reliably prevent misoperation.

[0119] In some embodiments, the total area of the capacitive recognition area 260 is greater than or equal to the total area of the pressure recognition area 250, and the projection of the capacitive recognition area 260 and the pressure recognition area 250 on the touchpad 100 (for example, on the outer surface or the inner surface 1000 of the touchpad 100) at least partially overlaps, and the overlapping part is shown by the cross-section line in FIG. 6. Since the pressing on the touchpad 100 can cause deformation of a larger area, even if the pressing position is outside the pressure recognition area 250, a certain pressure can be felt, and a pressure signal can be generated. By setting the area of the capacitive recognition area 260 to be greater than or equal to the area of the pressure recognition area 250, for example, by setting the number of the pressure recognition area 250 to be less than the number of the capacitive recognition area 260, the cost can be saved to a certain extent.

[0120] Further, the ratio of the total area of the overlapping part of the projection of the capacitive recognition area 260 and the pressure-sensing recognition area 250 on the touchpad 100 to the total area of the capacitive recognition area 260 is not less than 40%, so that when different positions of the touchpad 100 are operated, the changes of the capacitive signal and the pressure signal can be reliably generated at the same time, and the risk of only sensing the capacitive signal without the pressure signal or the pressure signal being too small is reduced. When the change value of the pressure signal is required to be greater than the first pressure signal threshold value before the control signal corresponding to the capacitive signal is output, the area ratio can be set as above, so that the control corresponding to the finger operation can be more sensitive. Further, the ratio of the total area of the overlapping part of the projection of the capacitive recognition area 260 and the pressure-sensing recognition area 250 on the touchpad 100 to the total area of the capacitive recognition area 260 is not less than 60%; further, the ratio of the total area of the overlapping part of the projection of the capacitive recognition area 260 and the pressure-sensing recognition area 250 on the touchpad 100 to the total area of the capacitive recognition area 260 is not less than 80%; further, the ratio of the total area of the overlapping part of the projection of the capacitive recognition area 260 and the pressure-sensing recognition area 250 on the touchpad 100 to the total area of the capacitive recognition area 260 is 1.

[0121] Optionally, the pressure-sensing recognition area 250 is located between two adjacent capacitive recognition areas 260 and extends to opposite to the two adjacent capacitive recognition areas 260, for example, extending to the position directly below the two adjacent capacitive recognition areas 260.

[0122] The application further provides a wearable device for executing the control method of the wearable device described above.

[0123] The wearable device can be a bone conduction earphone, for example. FIG. 7 shows a bone conduction earphone, which includes a first earphone head 40, a second earphone head 41, a control compartment 42, a battery compartment 43, an ear hook 44, and a back hook 45. The first earphone head 40 and the control compartment 42 are connected by an ear hook 44, and the second earphone head 41 and the battery compartment 43 are connected by an ear hook 44. The control compartment 42 and the battery compartment 43 are connected by a back hook 45. Bone conduction vibration units are arranged in the first earphone head 40 and the second earphone head 41. In use, the first earphone head 40 and the second earphone head 41 are in contact with the human facial skin, and the vibration of the bone conduction vibration units is transmitted to the human body through the earphone head, realizing bone conduction sound transmission.

[0124] At least one of the first earphone head 40, the second earphone head 41, the control compartment 42 and the battery compartment 43 is provided with the touch plate 100 and the corresponding pressure sensing module 25 and the capacitive sensing module 26 to realize touch control of the bone conduction earphone. That is, the touch plate 100 can be arranged on only one component of the first earphone head 40, the second earphone head 41, the control compartment 42 and the battery compartment 43, or the touch plate 100 and the corresponding pressure sensing module 25 and the capacitive sensing module 26 can be arranged on two or more components of the first earphone head 40, the second earphone head 41, the control compartment 42 and the battery compartment 43.

[0125] As a preferred embodiment, the control compartment 42 is provided with the touch plate 100 and the corresponding pressure sensing module 25 and the capacitive sensing module 26. Since the control circuit board 3 of the bone conduction earphone is usually arranged in the control compartment 42, arranging the touch plate 100 and the corresponding pressure sensing module 25 and the capacitive sensing module 26 on the control compartment 42 can facilitate wiring of the sensor (i.e., the pressure sensing module 25 and the capacitive sensing module 26 described above) and the control circuit board 3. At the same time, the control compartment 42 has a large surface area, which can form a larger touch area 101 and facilitate control. It can be understood that when the touch plate 100 is arranged on other components, it can be connected to the control circuit board 3 in the control compartment 42 through a wire to transmit an electrical signal.

[0126] In other embodiments, the wearable device can also be a bone conduction glasses, a watch, a wristband, etc.

[0127] Hereinafter, the control compartment 42 provided with the touch plate 100 and the corresponding pressure sensing module 25 and the capacitive sensing module 26 is taken as an example to introduce the touch control structure for realizing the above-mentioned touch control. It can be understood that the touch control structure can also be applied to other components, such as the earphone head and the battery compartment, at this time, the shell assembly 1 is the shell assembly 1 of the earphone head and the battery compartment 43.

[0128] As shown in FIG. 8, the control compartment 42 includes the shell assembly 1, the touch sensing assembly 2 and the control circuit board 3. The touch sensing assembly 2 includes the capacitive sensing module 26 and the pressure sensing module 25.

[0129] The shell assembly 1 is connected by two or more than two shells. As shown in FIG. 8, the shell assembly 1 includes the first shell 11 and the second shell 12 connected to each other, and the first shell 11 and the second shell 12 are spliced along the thickness direction to seal the respective openings. When the first shell 11 and the second shell 12 are not connected, the components can be installed in the shell through the opening.

[0130] The first shell 11 is provided with the touch plate 100, which is located on the outer side of the wearable device when the wearable device is worn, and is not arranged close to the human body to prevent being blocked by the human body. The surface of the touch plate 100 facing the outer side is provided with a touch area 101, and the position of the touch area 101 is schematically shown by a dashed line in FIG. 9.

[0131] In the embodiment shown in FIG. 8, the touch plate 100 and the first shell 11 are separately arranged, and the two can be connected by, for example, adhesion. In other embodiments, the touch plate 100 and the first shell 11 can also be integrally injection molded.

[0132] As shown in FIGS. 11 and 12, the touch sensing assembly 2 is arranged in the shell assembly 1 and connected to the touch plate 100. The capacitive sensing module 26 and the pressure sensing module 25 are arranged along the thickness direction Z of the touch plate 100, and the capacitive sensing module 26 is closer to the touch plate 100. In other embodiments, the pressure sensing module 25 can also be arranged to be closer to the touch plate 100. The capacitive sensing module 26 is provided with a capacitive sensor. When a finger contacts the touch plate 100, the electric field distribution and the capacitance between the capacitive sensing electrodes of the capacitive sensor will change, and a corresponding capacitive signal is output.

[0133] The pressure sensing module 25 is arranged corresponding to the touch plate 100 and is used to detect the pressure signal of the touch plate 100. The pressure sensing module 25 includes a pressure sensor. When the touch plate 100 is stressed, the touch plate 100 will be deformed and drive the pressure sensor to also be deformed, and thus the pressure sensor generates a corresponding pressure signal.

[0134] The control circuit board 3 is electrically connected to the capacitive sensing module 26 and the pressure sensing module 25, and can receive the capacitive signal transmitted by the capacitive sensing module 26 and the pressure signal transmitted by the pressure sensing module 25.

[0135] As described above, the control circuit board 3 can switch the wearable device to a water touch control mode or a non-water touch control mode according to the capacitive signal. In the non-water touch control mode, the control circuit board 3 generates a corresponding control signal according to the change of the capacitive signal. In the water touch control mode, the control circuit board 3 generates a corresponding control signal according to the change of the pressure signal, so that the wearable device can be controlled regardless of whether there is liquid in the touch area.

[0136] The touchpad 100, the capacitive sensing module 26 and the pressure sensing module 25 are arranged in sequence along the thickness direction Z of the touchpad 100, and the capacitive sensing module 26 is connected to the inner surface of the touchpad 100, for example, by means of adhesion, so as to reduce the distance between the capacitive sensing module 26 and the outer surface of the touchpad 100 and improve the sensitivity of capacitive sensing. Further, since the touchpad 100, the capacitive sensing module 26 and the pressure sensing module 25 are arranged in sequence, when the finger operates the touchpad 100, the capacitive sensing module 26 and the pressure sensing module 25 can reliably detect the changes of the capacitive signal and the pressure signal at the same time.

[0137] In some embodiments, as shown in FIG. 12 and FIG. 13, the touch sensing assembly 2 further comprises a flexible circuit board 20 electrically connected to the control circuit board 3. As shown in FIG. 14 and FIG. 15, the flexible circuit board 20 comprises a first board portion 200 and a second board portion 201, the capacitive sensing module 26 is arranged on the first board portion 200, and the pressure sensing module 25 is arranged on the second board portion 201, and the first board portion 200 is attached to the inner surface of the touchpad 100. Since the flexible circuit board 20 is flexible, the first board portion 200 and the second board portion 201 can be arranged opposite to each other by bending the flexible circuit board 20, so as to facilitate the arrangement of the positions of the capacitive sensing module 26 and the pressure sensing module 25. FIG. 15 shows a schematic view of the flexible circuit board 20 before being bent, and three pressure sensing recognition areas 250 and four capacitive sensing recognition areas 260 are shown in the figure. FIG. 14 shows a schematic view of the flexible circuit board 20 after being bent. Alternatively, the first board portion 200 and the second board portion 201 are parallel. In addition, the flexible circuit board 20 is connected to the control circuit board 3, so as to facilitate the electrical connection between the capacitive sensing module 26 and the pressure sensing module 25 and the control circuit board 3.

[0138] In some embodiments, the control circuit board 3 is arranged in the housing assembly 1, and the flexible circuit board 20 comprises a third board portion 203 connected to the first board portion 200 or the second board portion 201, and preferably, the third board portion 203 is connected to the second board portion 201, so as to facilitate the arrangement of the third board portion 203. As shown in FIG. 13 and FIG. 16, the first housing 11 is provided with a through hole 110, the touchpad 100 covers the surface of the through hole 110 and is arranged in the mounting groove 111 on the surface of the first housing 11, the first board portion 200 is located in the through hole 110, and the second board portion 201 is relatively close to the outside of the through hole 110. Therefore, the third board portion 203 is arranged to be connected to the second board portion 201, so as to facilitate the reduction of the interference of the housing and the convenience of wiring.

[0139] The end of the third plate part 203 is provided with a connecting terminal 24 connected with the control circuit board 3, the connecting terminal 24 can be plugged with the control circuit board 3, and the connection is more convenient. The touch sensing assembly 2 further comprises a reinforcing plate 27 connected with the third plate part 203, the reinforcing plate 27 and the connecting terminal 24 are correspondingly arranged, and the reinforcing plate 27 and the connecting terminal 24 are respectively located on opposite sides of the third plate part 203, so as to improve the structural strength of the end of the third plate part 203 and improve the reliability of the connection. The reinforcing plate 27 can be made of metal or plastic, for example.

[0140] In some embodiments, as shown in FIGS. 12-14, the touch sensing assembly 2 further comprises a spacer 22 arranged between the first plate part 200 and the second plate part 201, and the first plate part 200 and the second plate part 201 are respectively attached to two opposite surfaces of the spacer 22, i.e. the pressure sensing module 25 and the capacitive sensing module 26 are respectively connected to the two opposite surfaces of the spacer 22. By arranging the spacer 22, the deformation of the touch plate 100 can be transmitted to the second plate part 201 and sensed by the pressure sensing module 25. The spacer 22 can be made of glass fiber, polyester film, polyimide film or polyamide film, for example.

[0141] In some embodiments, referring to FIGS. 18 and 19, the spacer 22 comprises a plurality of spaced grooves 220, and the grooves 220 pass through both ends of the spacer 22. By arranging the grooves 220, it is more convenient for the spacer 22 to deform, so that the pressure sensing module 25 is more sensitive to the pressing of the finger. Optionally, at least one groove 220 is arranged in each pressure sensing recognition area 250 to further improve the sensitivity of the pressure sensing module 25 to pressure sensing. FIG. 19 shows a case where one groove 220 is arranged in the middle of one pressure sensing recognition area 250. The grooves 220 can be arranged on the surface of the spacer 22 facing the second plate part 201, or on the surface of the spacer 22 facing the first plate part 200.

[0142] Optionally, the extension direction of the groove 220 is perpendicular to the arrangement direction of the pressure sensing recognition area 250, so that when the part of the spacer 22 corresponding to the groove 220 is stressed, the groove 220 deforms greatly, while the deformation of other grooves 220 is small or even no deformation. In this way, only the pressure sensing recognition area 250 corresponding to the groove 220 can identify a larger pressure, and the identification is more accurate.

[0143] In some embodiments, the pressure sensing module 25, the capacitive sensing module 26 and the spacer 22 are all in the shape of a long strip (e.g. a rectangle), and the length direction X is consistent, and correspondingly, the touch area 101 is also in the shape of a long strip. The groove 220 is arranged along the width direction Y of the spacer 22 and penetrates through both ends of the width direction Y of the spacer 22. The capacitive sensing area 260 and the pressure sensing area 250 are both arranged along the length direction X of the spacer 22, and when the touchpad 100 is operated by sliding, the sliding is along the length direction of the spacer 22, so that the sliding range of the finger is larger and the operation is more convenient and the gesture is more accurately recognized.

[0144] Optionally, the thickness D of the spacer 22 is in the range of 0.2-1mm, the ratio of the depth H of the groove 220 to the thickness D of the spacer 22 is in the range of 0.2-0.8, and the width W of the groove 220 is in the range of 0.3-2mm, so that the spacer 22 can reliably deform. Further optionally, the thickness D of the spacer 22 is in the range of 0.3mm-0.6mm, so that the spacer 22 reliably transmits the deformation of the touchpad 100 while the thickness range is more reasonable and the occupation of the internal space is reduced.

[0145] The wearable device described above can be controlled in the following manner.

[0146] The control method of the wearable device includes the following steps:

[0147] When the touchpad 100 of the wearable device is not covered by water, a pressure greater than the first pressure signal threshold is applied to the touchpad 100 for operation, and the operation mode can be, for example, clicking and sliding.

[0148] When the touchpad 100 of the wearable device is covered by water, a pressure greater than the second pressure signal threshold is applied to the touchpad 100 for operation, and the operation mode can be, for example, clicking and sliding.

[0149] The second pressure signal threshold is greater than the first pressure signal threshold. Optionally, the first pressure signal threshold is greater than or equal to 10g, and the second pressure signal threshold is any value in the range of 30-100g.

[0150] In some embodiments, when the touchpad 100 is slid, the volume of the wearable device can be adjusted, and when the touchpad 100 is double-clicked, the voice assistant can be woken up. Optionally, the faster the sliding touch speed is, the faster the volume change speed is, and vice versa, the slower the sliding touch speed is, the slower the volume change speed is.

[0151] Optionally, when the control circuit board 3 performs corresponding actions, feedback is given in the form of voice. For example, when the control circuit board 3 switches the control mode, a prompt sound can be emitted to prompt the current control mode, and the prompt sound can be, for example, “switched to water-touch control mode”, “switched to non-water-touch control mode”, etc.

[0152] Similarly, when the control circuit board 3 performs operations such as increasing / decreasing the volume, opening the voice assistant, etc., corresponding prompt sounds are also emitted, so that the user can clearly know whether the operation of the user is accurately recognized by the wearable device. Further, when the volume is decreased to the minimum or increased to the maximum, corresponding prompt sounds can also be emitted to prompt the user that there is no need to continue to increase or decrease the volume, which is convenient for use.

[0153] The above is only a specific embodiment of the present application, and any improvement made on the basis of the concept of the present application is considered to be within the protection scope of the present application.
