[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please refer to Figure 1, which is a flowchart of the steps of the touch recognition method for the side-connected button provided by an embodiment of the present invention. Specifically, please refer to Figure 2, which is a schematic structural diagram of the side-connected button provided by an embodiment of the present invention. The side-connected button includes at least two transducer units corresponding to the button structure (volume + button and volume - button), and at least one sensor unit arranged between the transducer units. Unless otherwise specified, the embodiment of the present invention is described as a case where a side-connected button has two button structures, wherein two transducer units are correspondingly provided and one sensor unit is provided. The touch recognition method includes the following steps:

[0037] S101: Acquire a touch main signal of a side integrated button through the sensor unit.

[0038] Specifically, the embodiment of the present invention designs the sensor unit and the transducer unit to respectively collect touch signals. For distinction, the signal collected by the sensor unit is the main touch signal, and the signal collected by the transducer unit is the auxiliary touch signal.

[0039] The sensor unit is a pressure sensor or a proximity sensor. This type of sensor belongs to a pressure-sensitive sensor, wherein the sensor unit is arranged between different transducer units. When the side integrated button is touched and displaced, the sensor unit monitors the external changes and generates a pressure-sensitive signal, that is, the main touch signal is the pressure-sensitive signal collected by the sensor unit. In other possible implementations, multiple sensor units are arranged between different transducer units to improve the recognition accuracy of the main touch signal. This can be set according to the button structure and actual needs.

[0040] S102: Acquire a touch auxiliary signal of the side integrated button through different transducer units.

[0041] The side-connected button in this embodiment of the present invention is a piezoelectric ceramic device. Piezoelectric ceramic devices have excellent piezoelectric properties. The transducer unit is directly mounted on the side-connected button. When the side-connected button is touched, a piezoelectric signal is generated, which is directly captured by the transducer unit. In other words, the touch auxiliary signal is the piezoelectric signal captured by the transducer unit via the piezoelectric ceramic device. During implementation, the transducer unit can be implemented using a bow-shaped transducer based on the shape of the button structure.

[0042] Since the side-connected button itself has a multiple button structure, the transducer unit in the embodiment of the present invention also needs to be set according to its quantity. However, the signals collected by different transducer units can be distinguished separately, such as the first touch auxiliary signal, the second touch auxiliary signal, etc., so as to expand the recognition function by analyzing the generation and size of different signals.

[0043] S103: Perform threshold recognition on the main touch signal and the auxiliary touch signals obtained by different transducer units to obtain a touch recognition result.

[0044] The side integrated button itself has the function of a button. However, with the continuous innovation of science and technology, the integrated button made of piezoelectric ceramic material can also generate different signals by sliding, thereby expanding the functions of devices such as watches and mobile phones. The embodiment of the present invention performs touch recognition based on the specific threshold value of the touch main signal and the touch auxiliary signal obtained by the different transducer units. This threshold value can be processed before recognition for comparison. Since the generation methods of piezoelectric data and pressure-sensitive data are different, the piezoelectric data can be directly read by the data processing unit, while the pressure-sensitive data may need to be converted into an electrical signal through the ADC unit. The specific processing process can be designed according to actual needs.

[0045] The touch recognition result includes:

[0046] If the touch main signal and the touch auxiliary signals acquired by at least two of the transducer units are both greater than a preset sliding recognition threshold, it is recognized as a sliding action;

[0047] If the touch main signal and the touch auxiliary signal acquired by at least one of the transducer units are both smaller than a preset sliding recognition threshold, it is recognized as a pressing action.

[0048] The existing technology can judge a pressing action based on the signal collected by a single transducer unit. However, a typical sliding action is sliding from one side of the side-connected button to the other side. In this case, the existing technology method is no longer applicable. The multiple transducer units provided in the embodiment of the present invention will collect the auxiliary touch signal, and under certain conditions, a smaller main touch signal will also be collected. Since the sliding action is different from the pressing action and does not press the button structure, the preset sliding threshold designed in the embodiment of the present invention can clearly identify the occurrence of the sliding action.

[0049] S104: Determine a preset touch event occurring on the side integrated button based on the touch recognition result, and generate corresponding touch data.

[0050] The preset touch events include:

[0051] Slide on the side button;

[0052] Press the side button.

[0053] The touch data in the embodiment of the present invention is relative to devices such as watches and mobile phones. The touch data itself can also be used as an identification result. When the touch recognition method of the side integrated button proposed in the embodiment of the present invention is applied to a smart device, the processing unit of the smart device can recognize the corresponding touch event based on the touch data and enable or implement a certain function.

[0054] It should be noted that the side-connected buttons based on piezoelectric ceramic devices can be designed with more touch actions according to the usage scenarios, such as sliding, slight sliding, bidirectional sliding and other touch actions after pressing the button structure. Based on the touch recognition method of the side-connected buttons proposed in the embodiment of the present invention, different signal acquisition units are used, combined with the analysis process of piezoelectric and pressure-sensitive data, different preset touch events can be set to correspond, which can further enrich the functions of watches, mobile phones and other devices.

[0055] Compared to related technologies, the present invention proposes a touch recognition method for a side-connected key, wherein the side-connected key includes at least two transducer units corresponding to the key structure and at least one sensor unit disposed between the transducer units. The touch recognition method comprises the following steps: obtaining a primary touch signal of the side-connected key through the sensor unit; obtaining an auxiliary touch signal of the side-connected key through different transducer units; performing threshold recognition on the primary touch signal and the auxiliary touch signals obtained by the different transducer units to obtain a touch recognition result; and determining a preset touch event occurring on the side-connected key based on the touch recognition result and generating corresponding touch data. In the above method, the present invention identifies touch events through a signal acquisition unit specifically disposed in the connected key, which can reduce interference with touch recognition caused by different adjacent key structures in the solid-state connected key. Furthermore, the present invention uses both pressure-sensitive and piezoelectric sensing methods to collect touch signals, and by collaboratively processing the two types of signals, improves the recognition accuracy of touch modes such as pressing and sliding of the solid-state connected key structure.
