Description

Technical Field

[0001] This application relates to the technical field of audio keys. More specifically, it relates to a touch-based audio control key and an audio control method. Background Art

[0002] In the key design of audio devices, mechanical keys and touch keys are currently the two most common types of keys. When a mechanical key is pressed, there is an obvious tactile feedback and sound prompt, which enables users to accurately perceive the position and state of the key during operation. The design of mechanical keys is relatively simple, easy to integrate into various audio devices, and suitable for stable operation in a vibrating environment. However, mechanical keys are prone to dust accumulation, and mechanical keys may fail after long-term use.

[0003] Touch keys, on the other hand, detect the finger movements of users through touch sensors and can be operated without physical force. The advantages of touch keys are that the overall appearance is more concise, there is no obvious height difference on the touch keys, the touch control is easy, and it is not easy to accumulate dust. When an audio is used outdoors, due to more dust in the outdoor environment, it affects the sensitivity and service life of the keys, making the audio may be affected by dust during use, and the mechanical keys of the audio may be affected by dust and fail. Therefore, setting touch keys on the audio can improve the use effect of the audio. However, when the audio is used outdoors, the touch panel is prone to accidental touch or affected by the surrounding environment, resulting in a poor control experience when the audio is used outdoors. Summary of the Invention

[0004] The purpose of this application is to provide a touch-based audio control key and an audio control method, which solve the technical problems that the touch panel of the audio is prone to accidental touch and is easily affected by the surrounding environment when used outdoors, and achieve the technical effect of avoiding accidental touch of the touch panel of the audio and avoiding the influence of the surrounding environment when used outdoors.

[0005] A touch-based audio control key provided by an embodiment of this application includes: a touch panel for emitting a sliding touch signal in response to a user's sliding touch operation, including a first detection area and a second detection area, and the second detection area is annular and arranged on the circumference of the first detection area; wherein, the sliding touch signal includes a sliding touch direction and a sliding touch distance; a touch detection component for determining a first average capacitance change value of the sliding touch signal in the first detection area and for determining a second average capacitance change value of the sliding touch signal in the second detection area; a control component electrically connected to the touch panel and the touch detection component respectively, for issuing corresponding control instructions according to the first average capacitance change value, the second average capacitance change value, the sliding touch direction and the sliding touch distance.

[0028] When the sound device is used outdoors, the touchpad is prone to accidental touch or affected by the surrounding environment, resulting in a poor control experience when the sound device is used outdoors.

[0029] For the above reasons, the embodiments of this application provide a touch-based sound device control button, including: a touchpad for generating a sliding touch signal in response to a user's sliding touch operation, including a first detection area and a second detection area, where the second detection area is annular and disposed on the circumference of the first detection area; wherein the sliding touch signal includes a sliding touch direction and a sliding touch distance; a touch detection component for determining a first average capacitance change value of the sliding touch signal in the first detection area and for determining a second average capacitance change value of the sliding touch signal in the second detection area; and a control component electrically connected to the touchpad and the touch detection component respectively, for generating corresponding control instructions according to the first average capacitance change value, the second average capacitance change value, the sliding touch direction, and the sliding touch distance. The touch-based sound device control button in the embodiments of this application can avoid accidental touch of the sound device touchpad and can also avoid the influence of the surrounding environment on the sound device, improving the control effect when the sound device is used outdoors and enhancing the user experience.

[0030] In some scenarios, a touch-based sound device control button and a sound device control method in the embodiments of this application can be applied to sound devices used outdoors, improving the use effect of the touchpad of the sound device used outdoors, avoiding accidental touch of the touchpad, and also avoiding the influence of the outdoor environment on the sound device.

[0031] The following specifically describes a touch-based sound device control button provided by the embodiments of this application with specific examples.

[0032] Figure 1 is a schematic structural diagram of a touch-based sound device control button provided by the embodiments of this application. As Figure 1 shown, this touch-based sound device control button includes a touchpad 1, a touch detection component 2, and a control component 3. The touchpad 1, the touch detection component 2, and the control component 3 cooperate with each other to achieve touch control of the sound device.

[0033] As Figure 1As shown, the touchpad 1 is used to emit a sliding touch signal in response to a user's sliding touch operation. It includes a first detection area 11 and a second detection area 12. The second detection area 12 is annular and is provided on the circumference of the first detection area 11. Among them, the sliding touch signal includes a sliding touch direction and a sliding touch distance.

[0034] Structurally, in the embodiment of the present application, the touchpad 1 is used as a button for audio control. During operation, the touchpad 1 is used to emit a sliding touch signal in response to a user's sliding touch operation.

[0035] Exemplarily, the touchpad 1 can be a touchpad made of a conductive layer based on indium tin oxide (ITO).

[0036] As Figure 1 shown, the touchpad 1 can include a first detection area 11 and a second detection area 12. The second detection area 12 is annular and is provided on the circumference of the first detection area 11. Furthermore, the touch accuracy of the touchpad 1 is improved through the first detection area 11 and the second detection area 12 to prevent accidental touch.

[0037] Exemplarily, the hierarchical structures of the first detection area 11 and the second detection area 12 can be the same, and the first detection area 11 and the second detection area 12 are processed according to different control logics during signal processing to avoid accidental touch of the touchpad 1.

[0038] Exemplarily, the sliding touch signal can include a sliding touch direction and a sliding touch distance. The sliding touch direction is the touch direction during the sliding touch process, and the sliding touch distance is the touch distance during the sliding touch process.

[0039] Exemplarily, as Figure 1 shown in Figure a of Figure 1 , the touchpad 1 can be rectangular; as shown in Figure b of

[0040] As Figure 1 shown, the touch detection component 2 is used to determine the first average capacitance change value of the sliding touch signal in the first detection area 11 and is used to determine the second average capacitance change value of the sliding touch signal in the second detection area 12.

[0041] During operation, the touch detection component 2 is used to determine the first average capacitance change value of the sliding touch signal in the first detection area 11 and is used to determine the second average capacitance change value of the sliding touch signal in the second detection area 12. Furthermore, the detection of the sliding touch signal can be realized according to the first average capacitance change value and the second average capacitance change value in the first detection area 11 and the second detection area 12, avoiding accidental touch.

[0042] Figure 2 This is a schematic diagram of the control structure of a touch-based audio control button provided by an embodiment of the present application. As Figure 2 shown, in terms of structure, the control component 3 is electrically connected to the touchpad 1 and the touch detection component 2 respectively, and is used to issue corresponding control instructions according to the first average capacitance change value, the second average capacitance change value, the sliding touch direction, and the sliding touch distance.

[0043] In terms of structure, the control component 3 is electrically connected to the touchpad 1 and the touch detection component 2 respectively, so that the control component 3 can receive the sliding touch signal of the touchpad 1 and the detection structure of the touch detection component 2, and can be used to issue corresponding control instructions according to the first average capacitance change value, the second average capacitance change value, the sliding touch direction, and the sliding touch distance, and then achieve the purpose of sliding touch according to the control instructions, avoiding accidental touch of the touchpad 1.

[0044] The beneficial effects brought by the above implementation method are that by dividing the touchpad into a first detection area and a second detection area, and detecting the first average capacitance change value and the second average capacitance change value during the sliding touch process, and then issuing corresponding control instructions through the first average capacitance change value, the second average capacitance change value, the sliding touch direction, and the sliding touch distance, it can effectively avoid accidental touch and improve the control effect and use experience of the touchpad of the audio when in use.

[0045] In some implementation methods, in the above structure, issuing corresponding control instructions according to the first average capacitance change value, the second average capacitance change value, the sliding touch direction, and the sliding touch distance includes: when the first average capacitance change value is greater than or equal to the second average capacitance change value, and when the difference between the first average capacitance change value and the second average capacitance change value is greater than or equal to the preset capacitance change value difference, the control component 3 does not issue a control instruction. When the first average capacitance change value is less than the second average capacitance change value, and the difference between the second average capacitance change value and the first average capacitance change value is greater than or equal to the preset capacitance change value difference, the control component 3 issues corresponding control instructions according to the second sliding touch direction and the second sliding touch distance of the sliding touch signal in the second detection area 12. When the first average capacitance change value is less than the second average touch capacitance change value, and the difference between the second average capacitance change value and the first average capacitance change value is less than the preset capacitance change value difference, the control component 3 issues corresponding control instructions according to the first sliding touch direction and the first sliding touch distance of the sliding touch signal in the first detection area 11 and the second sliding touch direction and the second sliding touch distance of the sliding touch signal in the second detection area 12.

[0046] During operation, when the first average capacitance change value is greater than or equal to the second average capacitance change value, and when the difference between the first average capacitance change value and the second average capacitance change value is greater than or equal to the preset capacitance change value difference, it indicates that the difference in capacitance change values between the first detection area 11 and the second detection area 12 is too large. Furthermore, it can be shown that a touch has occurred in the first detection area 11, and there may be no touch operation in the second detection area 12. Consequently, it can be determined that a touch has occurred in the first detection area 11 and a false touch has occurred in the second detection area 12. Thus, it can be judged that this operation is not a valid sliding touch, and the control component 3 may not issue a control instruction for the sliding touch, thereby effectively avoiding false touches during the sliding touch of the touchpad 1.

[0047] During operation, when the first average capacitance change value is less than the second average capacitance change value, and when the difference between the second average capacitance change value and the first average capacitance change value is greater than or equal to the preset capacitance change value difference, it indicates that the capacitance change value in the second detection area 12 is larger than that in the first detection area 11. Furthermore, it can be determined that no touch operation has occurred in the first detection area 11 and a touch operation has occurred in the second detection area 12. Thus, it can be judged that the touch in the second detection area 12 is a valid touch operation, enabling the control component 3 to issue corresponding control instructions according to the second sliding touch direction and the second sliding touch distance within the second detection area 12 of the sliding touch signal, achieving effective control of the outdoor speaker.

[0048] When issuing corresponding control instructions according to the second sliding touch direction and the second sliding touch distance within the second detection area 12, it is possible to control the speaker according to the touch operation within the second detection area 12, improving the control effect of the speaker.

[0049] During operation, when the first average capacitance change value is less than the second average touch capacitance change value, and when the difference between the second average capacitance change value and the first average capacitance change value is less than the preset capacitance change value difference, it indicates that valid touches have occurred in both the first detection area 11 and the second detection area 12, and the touch processes in the first detection area 11 and the second detection area 12 are similar. It can be judged that no false touches have occurred in the first detection area 11 and the second detection area 12 of the touchpad 1.

[0050] When no false touches have occurred in the first detection area 11 and the second detection area 12, the control component 3 can issue corresponding control instructions according to the first sliding touch direction and the first sliding touch distance within the first detection area 11 of the sliding touch signal and the second sliding touch direction and the second sliding touch distance within the second detection area 12 of the sliding touch signal, achieving control of the speaker according to the touch operations in the first detection area 11 and the second detection area 12.

[0051] The beneficial effects brought by the above implementation method are as follows: when the first average capacitance change value is greater than or equal to the second average capacitance change value, and when the difference between the first average capacitance change value and the second average capacitance change value is greater than or equal to the preset capacitance change value difference, it is detected that a false touch occurs in the second detection area, realizing the detection of false touch in the second detection area.

[0052] The beneficial effects brought by the above implementation method also lie in that when the first average capacitance change value is less than the second average capacitance change value, and the difference between the second average capacitance change value and the first average capacitance change value is greater than or equal to the preset capacitance change value difference, it is detected that a false touch occurs in the first detection area, realizing the detection of false touch in the first detection area.

[0053] The beneficial effects brought by the above implementation method also lie in that when the first average capacitance change value is less than the second average touch capacitance change value, and the difference between the second average capacitance change value and the first average capacitance change value is less than the preset capacitance change value difference, it is determined that no false touch occurs in the first detection area and the second detection area, and it is possible to effectively detect the situation where no false touch occurs, and control the audio according to the touch process in the first detection area and the second detection area, improving the control effect of the touchpad.

[0054] In some implementation methods, the control component 3 issues corresponding control instructions according to the first sliding touch direction and the first sliding touch distance of the sliding touch signal in the first detection area 11, and the second sliding touch direction and the second sliding touch distance of the sliding touch signal in the second detection area 12, including: determining the first sliding touch trajectory of the sliding touch signal in the first detection area 11, and determining the second sliding touch trajectory of the sliding touch signal in the second detection area 12. When the first sliding touch trajectory and the second sliding touch trajectory are connected, the control component 3 issues corresponding control instructions according to the combined trajectory of the first sliding touch trajectory and the second sliding touch trajectory. When the first sliding touch trajectory and the second sliding touch trajectory are not connected, the control component 3 does not issue control instructions.

[0055] During operation, determine the first sliding touch trajectory of the sliding touch signal in the first detection area 11, and determine the second sliding touch trajectory of the sliding touch signal in the second detection area 12. When the first sliding touch trajectory and the second sliding touch trajectory are connected, it indicates that the first sliding touch trajectory and the second sliding touch trajectory are a continuous sliding touch process. Subsequently, the control component 3 can issue corresponding control instructions according to the combined trajectory of the first sliding touch trajectory and the second sliding touch trajectory, realizing the control of the audio according to the first sliding touch trajectory and the second sliding touch trajectory.

[0056] Exemplarily, a plurality of capacitors can be arranged in an array on the touchpad 1. When determining the first sliding touch trajectory of the sliding touch signal in the first detection area 11 and the second sliding touch trajectory of the sliding touch signal in the second detection area 12, the first sliding touch trajectory and the second sliding touch trajectory can be determined by the coordinates where the capacitance changes.

[0057] During operation, when the first sliding touch trajectory and the second sliding touch trajectory are not connected, it indicates that the touchpad 1 may have been accidentally touched. At this time, the control component 3 does not issue a control instruction, which can avoid accidental touching of the touchpad 1.

[0058] The beneficial effect brought by the above implementation is that by detecting the first sliding touch trajectory in the first detection area, detecting the second sliding touch trajectory of the sliding touch signal in the second detection area, judging whether the first sliding touch trajectory and the second sliding touch trajectory are connected, and judging whether to perform a sliding touch operation according to whether the first sliding touch trajectory and the second sliding touch trajectory are connected, it can avoid accidental touching during the touch process of the speaker and improve the control accuracy of the speaker touchpad.

[0059] The beneficial effect brought by the above implementation also lies in that in combination with the above method, when the first average capacitance change value is less than the second average touch capacitance change value, and the difference between the second average capacitance change value and the first average capacitance change value is less than the preset capacitance change value difference, then further judge whether the first sliding touch trajectory and the second sliding touch trajectory are connected, which can further avoid accidental touching of the touchpad and improve the control accuracy of the speaker touch button.

[0060] In some implementation manners, when the speaker control button is in use, it further includes: a capacitance fluctuation detection component 4, which is used to determine the first capacitance fluctuation value of the first average capacitance change value and the second capacitance fluctuation value of the second average capacitance change value within a preset historical time period. The control component 3 is further used to determine the difference between the first capacitance fluctuation value and the second capacitance fluctuation value as the fluctuation index. When the fluctuation index is greater than or equal to the preset fluctuation index, the control component 3 issues a corresponding control instruction according to the first average capacitance change value, the second average capacitance change value, the sliding touch direction and the sliding touch distance. When the fluctuation index is less than the preset fluctuation index, determine the fluctuation index difference between the preset fluctuation index and the fluctuation index, determine the interruption control time according to the fluctuation index difference, and the fluctuation index difference and the interruption control time are positively correlated. The control component 3 stops issuing control instructions within the interruption control time.

[0061] Such as Figure 2As shown, the device further includes a capacitance fluctuation detection component 4. The capacitance fluctuation detection component 4 is used to determine a first capacitance fluctuation value of a first average capacitance change value and a second capacitance fluctuation value of a second average capacitance change value within a preset historical time period, and then the working state of the audio control button can be controlled according to the first capacitance fluctuation value and the second capacitance fluctuation value.

[0062] Exemplarily, when determining the first capacitance fluctuation value of the first average capacitance change value within a preset historical time period, the first average capacitance change value within the preset historical time period can be obtained, and the variance value of the first average capacitance change value within the preset historical time period can be calculated as the first capacitance fluctuation value of the first average capacitance change value within the preset historical time period.

[0063] Exemplarily, the preset historical time period can be 5s, 10s or 15s.

[0064] During operation, the control component 3 is further used to determine the difference between the first capacitance fluctuation value and the second capacitance fluctuation value as a fluctuation index, and then the fluctuation index can be used as the control basis for the audio control button.

[0065] During operation, when the fluctuation index is less than the preset fluctuation index, it indicates that the capacitance change values in the first detection area 11 and the second detection area 12 within the preset historical time period are relatively stable, indicating that there is no accidental touch in the first detection area 11 and the second detection area 12 within the preset historical time period. The control component 3 issues corresponding control instructions according to the combined trajectory of the first sliding touch trajectory and the second sliding touch trajectory to realize the control of the audio control button.

[0066] During operation, when the fluctuation index is greater than or equal to the preset fluctuation index, it indicates that the difference between the first capacitance fluctuation value and the second capacitance fluctuation value in the first detection area 11 or the second detection area 12 may be large due to accidental touch. At this time, it is not suitable to control the audio according to the touch operation to improve the control accuracy of the audio.

[0067] When the fluctuation index is greater than or equal to the preset fluctuation index, the fluctuation index difference between the preset fluctuation index and the fluctuation index can be determined, and then the interruption control time can be determined according to the fluctuation index difference. The fluctuation index difference and the interruption control time are positively correlated, so that when the difference between the preset fluctuation index and the fluctuation index is larger, the interruption control time is larger. At the same time, the control component 3 can stop issuing control instructions within the interruption control time to avoid miscontrolling the audio due to accidental touch.

[0068] Exemplarily, when calculating the interruption control time according to the fluctuation index difference, the fluctuation index difference can be multiplied by the time control factor to obtain the interruption control time.

[0069] The beneficial effects brought by the above implementation method are as follows: the first capacitance fluctuation value of the first average capacitance change value and the second capacitance fluctuation value of the second average capacitance change value within a preset historical time period are determined, and the difference between the first capacitance fluctuation value and the second capacitance fluctuation value is determined as the fluctuation index. Then, whether the touchpad has a false touch is judged according to the fluctuation index, improving the control effect of the sound button.

[0070] The beneficial effects brought by the above implementation method also lie in that when the fluctuation index is less than the preset fluctuation index, corresponding control instructions are issued according to the combined trajectory of the first sliding touch trajectory and the second sliding touch trajectory to realize the control of the sound control button, ensuring the effective control of the sound button.

[0071] The beneficial effects brought by the above implementation method also lie in that when the fluctuation index is greater than or equal to the preset fluctuation index, the interruption control time is determined according to the fluctuation index difference, and the fluctuation index difference and the interruption control time are positively correlated, avoiding false touches of the touch button in subsequent time and improving the false touch control effect of the touch button.

[0072] In some implementation methods, it further includes a playback state detection component 5. The playback state detection component 5 is used to detect the playback state of the sound. When the sound is in the playback state, the interruption control time is shortened proportionally according to the reduction index; when the sound is in the non-playback state, the interruption control time remains unchanged.

[0073] As Figure 2 shown, the sound control button further includes a playback state detection component 5. The playback state detection component 5 is used to detect the playback state of the sound, and thus the false touch control process of the sound control button can be adjusted according to the playback state of the sound.

[0074] During operation, when the sound is in the playback state, it indicates that the user may currently need to control the sound, and the interruption control time can be shortened proportionally according to the reduction index to improve the user experience.

[0075] Exemplarily, when shortening the interruption control time proportionally according to the reduction index, the interruption control time can be multiplied by the reduction index to obtain the adjusted interruption control time.

[0076] During operation, when the sound is in the non-playback state, it indicates that the current user may not need to adjust the sound, and thus the interruption control time can remain unchanged, ensuring that the sound is not falsely touched and controlled.

[0077] It should be noted that the playback state detection component 5 can be integrally arranged on the sound control button or separated from the sound control button. The present application embodiment does not limit the setting position of the playback state detection component 5.

[0078] The beneficial effects brought by the above implementation method are that when the audio is in the playing state, the interruption control time is proportionally shortened according to the shrinking index, improving the user experience.

[0079] The beneficial effects brought by the above implementation method also lie in that when the audio is in the non-playing state, the interruption control time remains unchanged, thereby ensuring that the audio is not accidentally touched and controlled.

[0080] In some implementation methods, the playback state detection component 5 is also used to detect the playback state change information of the audio within a preset historical segment. When there is playback state change information within the preset historical segment, the interruption control time is set to 0; when there is no playback state change information within the preset historical segment, the interruption control time remains unchanged.

[0081] During operation, the playback state detection component 5 is also used to detect the playback state change information of the audio within a preset historical segment. The playback state change information of the audio reflects whether the working state of the audio has changed due to operation control, and thus the control process of the audio can be adjusted according to the playback state change information of the audio.

[0082] During operation, when there is playback state change information within the preset historical segment, it indicates that the playback state of the audio may have changed due to control operations within the preset historical time period. At this time, the interruption control time can be set to 0 to avoid affecting the normal operation of the user.

[0083] During operation, when there is no playback state change information within the preset historical segment, it indicates that the playback state of the audio has not changed due to control operations within the preset historical time period. At this time, the interruption control time can remain unchanged to avoid accidental touch and affecting the user experience.

[0084] The beneficial effects brought by the above implementation method are that when there is playback state change information within the preset historical segment, the interruption control time is set to 0 to avoid affecting the normal operation of the user.

[0085] The beneficial effects brought by the above implementation method also lie in that when there is no playback state change information within the preset historical segment, the interruption control time remains unchanged to avoid accidental touch and affecting the user experience.

When the first average capacitance change value is greater than or equal to the second average capacitance change value, and when the difference between the first average capacitance change value and the second average capacitance change value is greater than or equal to a preset capacitance change value difference, the control component 3 does not issue a control instruction. When the first average capacitance change value is less than the second average capacitance change value, and the difference between the second average capacitance change value and the first average capacitance change value is greater than or equal to the preset capacitance change value difference, the control component 3 issues a corresponding control instruction according to the second sliding touch direction and the second sliding touch distance of the sliding touch signal within the second detection area 12. When the first average capacitance change value is less than the second average touch capacitance change value, and the difference between the second average capacitance change value and the first average capacitance change value is less than the preset capacitance change value difference, the control component 3 issues a corresponding control instruction according to the first sliding touch direction and the first sliding touch distance of the sliding touch signal within the first detection area 11 and the second sliding touch direction and the second sliding touch distance of the sliding touch signal within the second detection area 12.

When the first sliding touch trajectory and the second sliding touch trajectory are not connected, the control component 3 does not issue a control instruction.

Determine the difference between the first capacitance fluctuation value and the second capacitance fluctuation value through the control component 3 as the fluctuation index.

[0095] S220. When the fluctuation index is greater than or equal to the preset fluctuation index, the control component 3 issues corresponding control instructions according to the first average capacitance change value, the second average capacitance change value, the sliding touch direction, and the sliding touch distance. When the fluctuation index is less than the preset fluctuation index, determine the fluctuation index difference between the preset fluctuation index and the fluctuation index, determine the interruption control time according to the fluctuation index difference, and the fluctuation index difference and the interruption control time are positively correlated.
