Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
As shown in fig. 1, a volume control method for an earphone according to an embodiment of the present invention is a method for controlling a volume of an earphone equipped with a plurality of touch keys, for example, two or more touch keys, wherein the method includes:
and S11, detecting the condition that the touch keys are touched in a preset time period to generate a first touch operation.
As to the implementation object of the embodiment of the present invention, it may be a processor of an earphone, it may be a main control processing unit MCU of the earphone and make an improvement thereon, or it may be an additional separately provided processor, and all of them fall within the protection scope of the present invention.
Specifically, the length of the predetermined time period is not limited herein, and may be used to indicate a time period required for the user to perform the effective touch operation. The first touch operation may be data corresponding to all touch actions received by the plurality of touch keys within a predetermined time period, or may be data corresponding to only a part of the touch actions received by the plurality of touch keys within the predetermined time period, and all of them are within the scope of the present invention. In order to achieve a more efficient processing effect, the embodiment of the invention recommends to screen out invalid data without disagreement in the detected data, and performs judgment and matching only based on the valid data; as an example, when one or more of the plurality of touch keys senses a touch action, the method may trigger detection of detection data about the plurality of touch keys being touched for a predetermined time period, and filter invalid action data in the detection data to obtain detection data corresponding to the first touch operation, wherein the invalid action data is used for indicating that any one of the plurality of touch keys is not touched within the predetermined time period, thereby reducing the amount of data processed later and improving the processing efficiency by filtering the invalid data.
And S12, judging whether the first touch operation is matched with a preconfigured volume control rule, wherein the volume control rule is used for indicating a preset combination of touch operations of a plurality of touch keys.
It should be noted that the volume control rule in this embodiment indicates that the combination of the touch operations of the plurality of touch keys is diversified, so that more functions (for example, increasing or decreasing the volume) can be implemented, and compared with a simple touch response for a touch key, a misoperation response can be avoided.
And S13, if the sound volume control command is matched with the sound volume control command, generating a corresponding sound volume control command.
In the embodiment, the preconfigured volume control rule is used to verify whether the detected touch actions received by the touch buttons of the touch headset meet the standard,
as shown in fig. 2, which shows a profile of the touch earphone under an example of applying the above embodiment, wherein the touch earphone has two first touch key 100 and second touch key 101 isolated from each other, the preconfigured volume manipulation rule may be a combination indicating touch operations with respect to the first touch key 100 and the second touch key 101, such as sliding touch from the first touch key 100 to the second touch key 101, sliding touch from the second touch key 101 to the first touch key 100 for a predetermined period of time, and so on.
Regarding the principle of judging a match in S12 of fig. 1, which may be an example with reference to fig. 3, the method includes:
s31, determining whether the first touch operation indicates a sliding motion between the first touch button and the second touch button within a predetermined time period, wherein the first touch button and the second touch button are arranged at intervals.
Regarding the determination and detection process of the sliding motion, it may be that when the first touch key and the second touch key are detected to be sequentially touched within a predetermined time period, for example, the single touch keys 100, 100 and 101, the single touch key 101 are detected to be sequentially touched and pressed, and no misjudgment motion for the first touch key and/or the second touch key is detected, the first touch operation is determined to indicate the sliding motion, wherein the misjudgment motion includes a long press motion (for example, the first control is pressed for more than 2 seconds and the like) and/or a double-click motion, it is understood that the misjudgment motion may also include other operations not used for indicating the sliding motion, thereby avoiding the misoperation of the volume control.
S32, if the first touch operation is an instruction of a sliding motion, determining that the first touch operation matches a preconfigured volume control rule.
And if the first touch operation does not indicate the sliding operation, determining that the first touch operation does not match the preconfigured volume control rule, and re-detecting the touch action of the user.
And S33, determining the sliding direction of the sliding action, and generating a corresponding volume increasing instruction or volume decreasing instruction according to the sliding direction.
As an example, as shown in fig. 2, if the determined sliding direction of the sliding motion is from bottom to top (from 101 to 100), a volume-up instruction is generated accordingly, and if the determined sliding direction of the sliding motion is from top to bottom (from 100 to 101), a volume-down instruction is generated accordingly. Although the number of the first touch keys and the second touch keys shown in fig. 2 is 1, it should be understood that the protection scope of the present invention is also covered by replacing the number of the first touch keys and the second touch keys with a plurality of the first touch keys and the second touch keys.
As shown in fig. 4, a volume control device 40 of an earphone according to an embodiment of the present invention includes a plurality of touch keys, wherein the device 40 includes:
a touch detection unit 401, configured to detect that the plurality of touch keys are touched in a predetermined time period, so as to generate a first touch operation;
a determining and matching unit 402, configured to determine whether the first touch operation matches a preconfigured volume manipulation rule, where the volume manipulation rule is used to indicate a predetermined combination of touch operations related to the plurality of touch keys;
a volume control command generating unit 403, configured to generate a corresponding volume control command if the volume control command is matched with the volume control command.
In some embodiments, the determining and matching unit 402 includes: the sliding action distinguishing module is used for determining whether the first touch operation indicates a sliding action between a first touch key and a second touch key within a preset time period, wherein the first touch key and the second touch key are arranged at intervals; and a matching determination module, configured to determine that the first touch operation matches a preconfigured volume manipulation rule if the first touch operation indicates the sliding motion.
In some embodiments, the volume manipulation instruction generation unit is configured to determine, if the first touch key and the second touch key are matched, a corresponding volume increase instruction or a volume decrease instruction according to a sliding direction between the first touch key and the second touch key within the predetermined time period.
In some embodiments, the sliding motion recognition module is configured to determine that the first touch operation indicates the sliding motion when it is detected that the first touch key and the second touch key are sequentially touched within the predetermined time period and no misjudgment motion for the first touch key and/or the second touch key is detected, where the misjudgment motion includes a long-press motion and/or a double-click motion.
In some embodiments, the touch detection unit includes: the trigger detection module is used for triggering and detecting detection data about the touch of the touch keys in the preset time period when one or more touch keys sense a touch action; and the invalid data filtering module is used for filtering invalid action data in the detection data, wherein the invalid action data is used for indicating that any one of the touch keys is not touched in the preset time period.
In an embodiment of the invention, the earphone is provided with two touch keys, and the volume adjustment is realized by sliding the two touch keys, so that the problem that the volume cannot be adjusted by the two touch keys is solved. The earphone volume adjustment is realized to convenience of sliding up and down of a user, and the user experience is improved. In a specific implementation strategy, a plurality of touch-control KEY values can be read through I2C communication on a touch chip, and a corresponding software algorithm is added to realize the functions of increasing the touch-control volume during the touch-up and reducing the touch-control volume during the touch-down.
The invention discloses a method for obtaining capacitance values and time differences triggered by a plurality of touch keys (touch key) of a touch chip through I2C communication of a main control chip, thereby calculating and judging the touch paddling direction, namely the direction of upward paddling or downward paddling, and realizing the functions of increasing the volume of a Bluetooth headset when the headset is paddled upward and reducing the volume when the headset is paddled downward. Fig. 5A is a wiring diagram of the main control chip, and fig. 5B is a wiring diagram of the touch chip. The network "SCL, SDA" is an I2C signal line, and connects the touch keys 100 and 101 for communication with the touch chip. "INT 1" is an interrupt signal for the touch chip to trigger the main control chip for touch response, and "PWDN" is a touch chip enable signal.
As shown in fig. 6A, first, after the earphone is powered on and initialized, the user touches the touch key to generate an interrupt and generate a corresponding touch value; and then, removing the invalid touch value to judge according to the valid touch value, wherein the judgment comprises the judgment of long pressing action, double clicking action and sliding action, when the judgment is that the touch is the sliding action, continuing the touch change direction path indicated by the valid touch value, and correspondingly generating a volume increasing instruction or a volume decreasing instruction to trigger volume increasing or decreasing operation. The method comprises the steps of reading a group of data through sliding, processing the read data, removing invalid data (reading the data all the time after the touch is pressed, stopping reading the data until the touch is completely released, possibly obtaining some data influencing sliding judgment in the data, mainly neglecting the data and sorting out the needed data), marking the valid data, and analyzing the data, wherein the data is mainly analyzed to determine what action the data is, and in a short time, the data can be clicked, double-clicked, long-pressed, or slid or other actions, and if numerical touch keys are changed and change along the same direction, the data is judged to be valid sliding.
As shown in fig. 6B, since the two-point touch key is used to realize sliding, when sliding, the following steps occur: key1 (touch point 1 pressed), key2 (touch point 1.2 pressed at the same time), key3 (touch point 2 pressed), key4 (touch point 1.2 released). In general, the Key4 sometimes appears in the head and tail data, which belongs to invalid data, and in order to judge the sliding state more efficiently, the Key4 data appearing in the head and tail needs to be removed. And judging valid data, namely judging whether keys 1 and 3 are all pressed effectively in the sliding process, analyzing the data, and if keys 1, 2, 3 or (key3, 2 and 1) appear in sequence, indicating that the action is in a sliding state, so that the volume is increased or decreased.
In the embodiment of the invention, because the volume up-down is realized by two-point touch control at this time, a distance of one point exists between two-point touch control keys, when the distance is less than a certain time from one contact point to the other contact point during sliding, the distance is judged to be effective sliding, and some invalid operation algorithms and some false triggering effects must be added into the two contact points during the volume up-down realization process, for example, false judgment of double-click occurs during two sliding or false judgment of double-click occurs during single-click is the situation of false judgment of sliding. This may increase accuracy.
