[0002] Mechanical buttons and touch buttons are the two most common types of buttons in audio equipment. Mechanical buttons have obvious tactile feedback and sound prompts when pressed, which allows users to accurately perceive the position and status of the buttons during operation. Mechanical buttons are relatively simple in design and easy to integrate into various audio equipment. They are suitable for stable operation in a vibrating environment, but they are prone to dust accumulation and may fail after long-term use.

[0003] Touch buttons detect the user's finger movements through touch sensors and can be operated without physical force. The advantages of touch buttons are that the overall appearance is simpler, there is no obvious height difference on the touch buttons, the touch control is easy, and it is not easy to accumulate dust. When the speaker is used outdoors, there is a lot of dust in the outdoor environment, which affects the sensitivity and service life of the buttons.

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

[0029] Based on the above reasons, the embodiment of the present application provides a touch-based audio control button, including: a touch pad, for responding to the user's sliding touch operation to send a sliding touch signal, including a first detection area and a second detection area, the second detection area is annular and arranged in 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 pad 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. The touch-based audio control button in the embodiment of the present application can avoid accidental touches on the audio touch pad, and can also avoid the audio being affected by the surrounding environment, thereby improving the control effect of the audio when used outdoors and improving the user experience.

[0030] In some scenarios, a touch-based audio control button and audio control method of an embodiment of the present application can be applied to audio systems for outdoor use, which can improve the use of the touchpad of the audio system for outdoor use, avoid accidental touches of the touchpad, and avoid the impact of the outdoor environment on the audio system.

[0031] The following is a detailed description of a touch-based audio control button provided in an embodiment of the present application with reference to a specific example.

[0032] Figure 1 A schematic diagram of a touch-based audio control button structure provided in an embodiment of the present application, such as Figure 1 As shown, the touch-based audio control button includes a touch panel 1, a touch detection component 2 and a control component 3. The touch panel 1, the touch detection component 2 and the control component 3 cooperate with each other to realize touch control of the audio.

[0033] like Figure 1As shown, the touch panel 1 is used to send a sliding touch signal in response to a user's sliding touch operation, and includes a first detection area 11 and a second detection area 12, wherein the second detection area 12 is annular and arranged on the circumference of the first detection area 11. The sliding touch signal includes a sliding touch direction and a sliding touch distance.

[0034] Structurally, the embodiment of the present application uses the touch panel 1 as a button to control the audio. When working, the touch panel 1 is used to send a sliding touch signal in response to the user's sliding touch operation.

[0035] Exemplarily, the touch panel 1 may be a touch panel made of a conductive layer made of indium tin oxide (ITO).

[0036] like Figure 1 As shown, the touch panel 1 may include a first detection area 11 and a second detection area 12. The second detection area 12 is annular and arranged circumferentially of the first detection area 11. The touch accuracy of the touch panel 1 is improved by the first detection area 11 and the second detection area 12 to prevent accidental touches.

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

[0038] Exemplarily, the sliding touch signal may include a sliding touch direction and a sliding touch distance, wherein the sliding touch direction is a touch direction of the sliding touch process, and the sliding touch distance is a touch distance of the sliding touch process.

[0039] For example, Figure 1 As shown in Figure a, the touch panel 1 may be rectangular; Figure 1 As shown in Figure b, the touch panel 1 can be circular, and the shape of the touch panel 1 can be set according to requirements and is not limited here.

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

[0041] When working, 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 to determine the second average capacitance change value of the sliding touch signal in the second detection area 12. Then, the sliding touch signal can be detected 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 to avoid false touches.

[0042] Figure 2 A schematic diagram of a control structure of a touch-based audio control button provided in an embodiment of the present application, such as Figure 2 As shown, structurally, the control component 3 is electrically connected to the touch panel 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] Structurally, the control component 3 is electrically connected to the touch pad 1 and the touch detection component 2, respectively, so that the control component 3 can receive the sliding touch signal of the touch pad 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 sliding touch purpose according to the control instructions to avoid accidental touch of the touch pad 1.

[0044] The beneficial effect brought about by the above-mentioned implementation method is that by dividing the touch pad 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 touches and improve the control effect and usage experience of the touch pad of the audio system when in use.

[0045] In some implementations, 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 means that the capacitance change value difference between the first detection area 11 and the second detection area 12 is too large, which may indicate that a touch has occurred in the first detection area 11 and no touch operation may have occurred in the second detection area 12. It can be judged that a touch has occurred in the first detection area 11 and an error touch has occurred in the second detection area 12. 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 error touches of the touch panel 1 during sliding touch.

[0047] During operation, 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 means that the capacitance change value on the second detection area 12 is larger than the capacitance change value on the first detection area 11, and it can be judged that no touch operation occurs on the first detection area 11 and a touch operation occurs on the second detection area 12, and it can be judged that the touch on the second detection area 12 is a valid touch operation, so that the control component 3 can issue corresponding control instructions according to the second sliding touch direction and the second sliding touch distance in the second detection area 12 according to the sliding touch signal, so as to realize effective control of the outdoor audio.

[0048] When a corresponding control instruction is issued according to the second sliding touch direction and the second sliding touch distance in the second detection area 12 , the audio can be controlled according to the touch operation in the second detection area 12 , thereby improving the control effect of the audio.

[0049] During operation, 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 indicates that effective touches have occurred on both the first detection area 11 and the second detection area 12, and the touch processes on the first detection area 11 and the second detection area 12 are similar, and it can be determined that no false touches have occurred on the first detection area 11 and the second detection area 12 of the touch pad 1.

[0050] When no false touch occurs in the first detection area 11 and the second detection area 12, the control component 3 can issue corresponding control instructions based on 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, so as to control the audio according to the touch operation of the first detection area 11 and the second detection area 12.

[0051] The beneficial effect brought about by the above-mentioned implementation method is that 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 has occurred in the second detection area, thereby realizing the detection of false touches in the second detection area.

[0052] The beneficial effect brought about by the above-mentioned implementation method is 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 has occurred in the first detection area, thereby realizing the detection of false touches in the first detection area.

[0053] The beneficial effect brought about by the above-mentioned implementation method is 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 judged that no false touch occurs in the first detection area and the second detection area, and the situation where no false touch occurs can be effectively detected, and the audio can be controlled according to the touch process in the first detection area and the second detection area, thereby improving the control effect of the touch panel.

[0054] In some implementations, 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 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 track of the sliding touch signal in the first detection area 11, and determining the second sliding touch track of the sliding touch signal in the second detection area 12, when the first sliding touch track and the second sliding touch track are connected, the control component 3 issues a corresponding control instruction according to the composite track of the first sliding touch track and the second sliding touch track. When the first sliding touch track and the second sliding touch track are not connected, the control component 3 does not issue a control instruction.

[0055] During operation, a first sliding touch trajectory of the sliding touch signal in the first detection area 11 is determined, and a second sliding touch trajectory of the sliding touch signal in the second detection area 12 is determined. 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. The subsequent control component 3 can issue corresponding control instructions according to the composite trajectory of the first sliding touch trajectory and the second sliding touch trajectory to realize the control of the audio according to the first sliding touch trajectory and the second sliding touch trajectory.

[0056] Exemplarily, a plurality of capacitors may be arrayed on the touch panel 1. When determining a first sliding touch trajectory of a sliding touch signal within a first detection area 11 and determining a second sliding touch trajectory of a sliding touch signal within a second detection area 12, the first sliding touch trajectory and the second sliding touch trajectory may be determined by the coordinates where the capacitance changes.

[0057] During operation, when the first sliding touch track and the second sliding touch track are not connected, it indicates that the touch panel 1 may be accidentally touched. At this time, the control component 3 does not issue a control instruction, thereby preventing the touch panel 1 from accidentally touching.

[0058] The beneficial effect brought about by the above-mentioned implementation method 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, and judging whether the first sliding touch trajectory and the second sliding touch trajectory are connected, and judging whether to perform a sliding touch operation based on whether the first sliding touch trajectory and the second sliding touch trajectory are connected, it is possible to avoid accidental touches in the audio touch process and improve the control accuracy of the audio touch panel.

[0059] The beneficial effect brought about by the above-mentioned implementation method is that, in combination with the above-mentioned 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, it is subsequently further determined whether the first sliding touch track and the second sliding touch track are connected, which can further avoid accidental touches of the touchpad and improve the control accuracy of the audio touch buttons.

[0060] In some implementations, when the audio control button is in use, it also includes: a capacitance fluctuation detection component 4, which 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. The control component 3 is also used to determine the difference between the first capacitance fluctuation value and the second capacitance fluctuation value as a 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, the fluctuation index difference between the preset fluctuation index and the fluctuation index is determined, and the interruption control time is determined according to the fluctuation index difference. The fluctuation index difference and the interruption control time are positively correlated, and the control component 3 stops issuing control instructions within the interruption control time.

[0061] like Figure 2As shown, the device also includes a capacitance fluctuation detection component 4, which 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 may 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 the fluctuation index can be used as a 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 no false touches occurred 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 composite trajectory of the first sliding touch trajectory and the second sliding touch trajectory to realize control of the audio control buttons.

[0066] During operation, when the fluctuation index is greater than or equal to the preset fluctuation index, it means that the difference between the first capacitance fluctuation value and the second capacitance fluctuation value may be large due to false touch in the first detection area 11 or the second detection area 12. 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 the greater the difference between the preset fluctuation index and the fluctuation index, the greater the interruption control time. At the same time, the control component 3 can stop issuing control instructions within the interruption control time to avoid miscontrol of the audio due to mis-touch.

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

[0069] The beneficial effect brought about by the above-mentioned implementation method is that 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 are determined, and a difference between the first capacitance fluctuation value and the second capacitance fluctuation value is determined as a fluctuation index, and then whether an accidental touch occurs on the touch panel is judged according to the fluctuation index, thereby improving the control effect of the audio button.

[0070] The beneficial effect brought about by the above implementation method is that when the fluctuation index is less than the preset fluctuation index, a corresponding control instruction is issued according to the composite trajectory of the first sliding touch trajectory and the second sliding touch trajectory to realize the control of the audio control button, thereby ensuring effective control of the audio button.

[0071] The beneficial effect brought about by the above-mentioned implementation method is 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, thereby avoiding accidental touches of the touch keys in the subsequent time and improving the accidental touch control effect of the touch keys.

[0072] In some implementations, a playing state detection component 5 is also included, and the playing state detection component 5 is used to detect the playing state of the audio. When the audio is in the playing state, the interruption control time is proportionally shortened according to the reduction index; when the audio is not in the playing state, the interruption control time is kept unchanged.

[0073] like Figure 2 As shown, the audio control button further includes a play status detection component 5, which is used to detect the play status of the audio, and then adjust the mis-touch control process of the audio control button according to the play status of the audio.

[0074] During operation, when the audio is in a playing state, it indicates that the user may need to control the audio at present. The interruption control time can be shortened proportionally according to the reduction index to improve the user experience.

[0075] Exemplarily, when the interruption control time is proportionally shortened according to the reduction index, the interruption control time and the reduction index may be multiplied to obtain the adjusted interruption control time.

[0076] During operation, when the speaker is not playing, it indicates that the current user may not need to adjust the speaker, so the interruption control time can be kept unchanged, thereby ensuring that the speaker is not controlled by accidental touch.

[0077] It should be noted that the playback status detection component 5 can be integrated on the audio control button, or can be separated from the audio control button. The embodiment of the present application does not limit the setting position of the playback status detection component 5.

[0078] The beneficial effect brought by the above implementation method is that when the speaker is in a playing state, the interruption control time is proportionally shortened according to the reduction index, thereby improving the user experience.

[0079] The beneficial effect brought about by the above implementation is that when the speaker is not in a playing state, the interruption control time is kept unchanged, thereby ensuring that the speaker is not controlled by accidental touch.

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

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

[0082] During operation, when there is playback status change information in the preset history segment, it means that the playback status of the audio may change due to control operation within the preset history 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 status change information in the preset history segment, it means that the playback status has changed due to no control operation of the audio system in the preset history period. At this time, the interruption control time can be kept unchanged to avoid accidental touches that affect the user experience.

[0084] The beneficial effect brought by the above implementation is that when there is playback status change information in the preset history segment, the interruption control time is set to 0 to avoid affecting the normal operation of the user.

[0085] The beneficial effect brought by the above implementation method is that, when there is no play status change information in the preset history segment, the interruption control time is kept unchanged to avoid accidental touches that affect the user's experience.

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 in the second detection area 12.

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

[0095] S220, 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, the fluctuation index difference between the preset fluctuation index and the fluctuation index is determined, and the interruption control time is determined according to the fluctuation index difference.
