[0042] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other arbitrarily.

[0043] An embodiment of this application provides a device supporting underwater touch operation, as Figures 1-10 shown, including a touch control module 100. The touch control module 100 includes a touch panel 2 and an elastic wave sensor assembly 1. The elastic wave sensor assembly 1 is fixed to the back of the touch panel 2. The elastic wave sensor assembly 1 is configured to detect an elastic wave signal caused by a touch action on the touch panel 2 and convert the elastic wave signal into an electrical signal.

[0044] The elastic wave sensor assembly includes an elastic wave sensor (such as the first elastic wave sensor 111 and / or the second elastic wave sensor 112 described below), and the elastic wave sensor can be a sensor with a piezoelectric effect, for example, a piezoelectric sensor, and the type of the piezoelectric sensor can include a piezoelectric ceramic sensor, a piezoelectric film sensor, and a piezoelectric crystal sensor. The elastic wave sensor is suitable for detecting elastic wave signals caused by touch actions on the touch panel 2 underwater. When a touch action is applied to the touch surface of the touch panel 2, the touch panel 2 and the corresponding part of the elastic wave sensor will be deformed. This deformation will cause an electric charge to be generated inside the elastic wave sensor, so that a voltage is generated between the positive and negative electrodes of the elastic wave sensor, and the voltage signal can be detected. When the touch module 100 is located underwater, the deformation of the elastic wave sensor caused by the touch action may be affected by water pressure. However, due to the characteristics of the piezoelectric circuit of the elastic wave sensor itself, the influence of water pressure on the elastic wave sensor can be eliminated. Under different water pressure conditions, the elastic wave sensor can self-calibrate the reference, so as to achieve being unaffected by changes in water pressure depth. In addition, the elastic wave sensor has a fast response speed to elastic wave signals and can quickly capture elastic wave signals. The elastic wave sensor can capture elastic wave signals with a wider frequency band, such as 0-100MHz, and has high sensitivity, which can reach the nanometer level. It can also capture elastic wave signals caused by tiny touch actions, and the elastic wave sensor can still respond quickly even when operating with gloves.

[0045] The device supporting underwater touch operation in the embodiment of the present application adopts an elastic wave sensor to detect elastic wave signals, and utilizes the characteristics of the piezoelectric circuit of the elastic wave sensor itself to avoid the influence of water pressure in an underwater environment or an environment in contact with water on the elastic wave signal detected by the elastic wave sensor, so that the elastic wave signal can be accurately and stably detected by the elastic wave sensor. In addition, the elastic wave sensor has a fast response speed to the elastic wave signal, can capture a large frequency range of elastic wave signals, for example, can capture high-frequency elastic wave signals, and has high sensitivity to the elastic wave signal.

[0046] In some exemplary embodiments, Figures 1 to 2b , Figure 4b , Figure 6b , Figure 8 , Figure 9As shown, the elastic wave sensor assembly 1 includes a plurality of elastic wave sensor units 11. The plurality of elastic wave sensor units 11 are arranged in at least one row and / or at least one column. The elastic wave sensor unit 11 includes a first elastic wave sensor 111 and a second elastic wave sensor 112. The first elastic wave sensor 111 and the second elastic wave sensor 112 are arranged in a T shape. The first elastic wave sensor 111 and the second elastic wave sensor 112 can be perpendicular to each other (for example, both the first elastic wave sensor 111 and the second elastic wave sensor 112 can be rectangular, and the length directions (extension directions) of the two can be perpendicular to each other), and are arranged in a T shape. For convenience, here the first elastic wave sensor 111 is defined as the horizontal sensor in the "T" shape, and the second elastic wave sensor 112 is defined as the vertical sensor in the "T" shape. The first elastic wave sensor 111 and the second elastic wave sensor 112 can be connected in parallel or in series with each other. Compared with using a single elastic wave sensor, or compared with the series connection of the first elastic wave sensor 111 and the second elastic wave sensor 112, or compared with other arrangements of the first elastic wave sensor 111 and the second elastic wave sensor 112, when the first elastic wave sensor 111 and the second elastic wave sensor 112 are arranged in a T shape and connected in parallel, the detection coverage is larger, the signal is better, which is beneficial to improving the detection sensitivity, and thus improving the sensitivity of the touch response.

[0047] In some exemplary embodiments, such as Figures 1-2b shown, the touch panel 2 is rectangular, and a plurality of elastic wave sensor units 11 are arranged in at least one row. The plurality of elastic wave sensor units 11 in each row (such as Figure 2a the two elastic wave sensor units 11 in the same row in the dashed box in Figure 4b and Figure 6bAs shown, for the elastic wave sensor units 11 arranged in a row, the first elastic wave sensors 111 can all extend along the length direction of the touch panel 2, and the second elastic wave sensors 112 can all extend along the width direction of the touch panel 2. The elastic wave sensor units 11 arranged in a row can be arranged near the long side edge of the touch panel 2, for example, arranged at one long side edge or the other long side edge of the rectangular touch panel 2. Of course, the elastic wave sensor units 11 arranged in a row can be arranged not near the long side edge of the touch panel 2, but at a certain distance from the long side edge of the touch panel 2.

[0048] In some exemplary embodiments, as Figures 1-2b and Figure 6b shown, multiple elastic wave sensor units 11 are arranged in multiple rows (at least two rows), and the multiple rows of elastic wave sensor units 11 are arranged in sequence along the width direction of the touch panel 2. Among them, as Figure 2b shown, the first elastic wave sensors 111 of the elastic wave sensor units 11 arranged in a row all extend along the width direction of the touch panel 2, the second elastic wave sensors 112 of the elastic wave sensor units 11 arranged in a row all extend along the length direction of the touch panel 2, and the second elastic wave sensors 112 of the elastic wave sensor units 11 arranged in a row can all be located on the same side of the first elastic wave sensors 111, that is, for all rows of elastic wave sensor units 11, the second elastic wave sensors 112 can all be located on the first side of the first elastic wave sensors 111 (for example: near one wide side of the rectangular touch panel 2) or the second elastic wave sensors 112 can all be located on the second side of the first elastic wave sensors 111 (for example: near the other wide side of the rectangular touch panel 2), where the first side and the second side are opposite sides of the first elastic wave sensors 111. Or, as Figure 1 and 2a shown, for each row of elastic wave sensor units 11, the second elastic wave sensors 112 of the elastic wave sensor units 11 in the same row can all be located on the same side of the first elastic wave sensors 111; and for adjacent rows of elastic wave sensor units 11, the second elastic wave sensors 112 of the adjacent rows of elastic wave sensor units 11 can be located on opposite sides of the first elastic wave sensors 111 respectively. For example, the second elastic wave sensors 112 of one row of elastic wave sensor units 11 can all be located on the first side of the first elastic wave sensors 111, and the second elastic wave sensors 112 of the adjacent row of elastic wave sensor units 11 can all be located on the second side of the first elastic wave sensors 111.

[0049] As Figure 2b shown, in each of the elastic wave sensor units 11 in the left row and the right row, the second elastic wave sensors 112 can all be arranged on the upper side (or lower side) of the first elastic wave sensors 111. AsFigure 2a As shown, in each of the elastic wave sensor units 11 in the left row, the second elastic wave sensor 112 can be arranged on the lower side of the first elastic wave sensor 111; while in each of the elastic wave sensor units 11 in the right row, the second elastic wave sensor 112 can be arranged on the upper side of the first elastic wave sensor 111, so that the T shapes formed by the elastic wave sensor units 11 in the left and right rows are 180 degrees different. Figure 2a In it, the second elastic wave sensor 112 located on the lower side of the first elastic wave sensor 111 in the left row of elastic wave sensor units 11 and the second elastic wave sensor 112 located on the upper side of the first elastic wave sensor 111 in the right row of elastic wave sensor units 11 cooperate to detect touch actions on the touch areas at various positions such as the lower and upper parts of the touch panel 2, making the detection range of the elastic wave sensor assembly 1 as a whole wider and the detection sensitivity higher.

[0050] In some exemplary embodiments, as Figure 6b shown, multiple elastic wave sensor units 11 are arranged in multiple rows (two rows in the figure) and also in multiple columns (two columns in the figure). The two rows of elastic wave sensor units 11 are arranged in sequence along the width direction of the touch panel (as Figure 6b in it, the two rows of elastic wave sensor units 11 can be arranged one above the other), the multiple elastic wave sensor units 11 in each column are arranged in sequence along the width direction of the touch panel, and the two columns of elastic wave sensor units 11 are arranged in sequence along the length direction of the touch panel (as Figure 6b in it, the two columns of elastic wave sensor units 11 can be arranged one on the left and one on the right), and the two columns of elastic wave sensor units 11 can be arranged near the edge of the touch panel 2, for example, arranged at the left edge and the right edge of the touch panel 2. Among them: the first elastic wave sensors 111 of the elastic wave sensor units 11 arranged in rows all extend along the length direction of the touch panel, the second elastic wave sensors 112 of the elastic wave sensor units 11 arranged in rows all extend along the width direction of the touch panel, and are located on the side of the first elastic wave sensor 111 facing the center of the touch panel (as Figure 6b in it, the second elastic wave sensor 112 of the elastic wave sensor unit 11 in the upper row can be located on the lower side of the first elastic wave sensor 111, and the second elastic wave sensor 112 of the elastic wave sensor unit 11 in the lower row can be located on the upper side of the first elastic wave sensor 111); the first elastic wave sensors 111 of the elastic wave sensor units 11 arranged in columns all extend along the width direction of the touch panel, the second elastic wave sensors 112 of the elastic wave sensor units 11 arranged in columns all extend along the length direction of the touch panel, and are located on the side of the first elastic wave sensor facing the center of the touch panel (as Figure 6bIn the [description], the second elastic wave sensor 112 of the elastic wave sensor unit 11 in the left column may be located on the right side of the first elastic wave sensor 111, and the second elastic wave sensor 112 of the elastic wave sensor unit 11 in the right column may be located on the left side of the first elastic wave sensor 111. Alternatively, the second elastic wave sensor 112 of the elastic wave sensor unit 11 in the same column is alternately located on the side facing the center of the touch panel 2 of the first elastic wave sensor 111 and on the side facing away from the center of the touch panel 2 of the first elastic wave sensor 111.

[0051] In some exemplary embodiments, as Figure 4b shown, a plurality of elastic wave sensor units 11 are arranged in a row along the length direction of the touch panel 2, and the first elastic wave sensors 111 of the plurality of elastic wave sensor units 11 all extend along the length direction of the touch panel, and the second elastic wave sensors 112 of the plurality of elastic wave sensor units 11 all extend along the width direction of the touch panel. The second elastic wave sensors 112 of two adjacent elastic wave sensor units 11 are located on opposite sides of the first elastic wave sensor 111. For example, as Figure 4b shown, in each elastic wave sensor unit 11, the second elastic wave sensor 112 is alternately located above or below the first elastic wave sensor 111.

[0052] In some exemplary embodiments, as Figure 8 and Figure 9 shown, the touch panel 2 is circular, a plurality of elastic wave sensor units 11 are arranged along the circumferential direction of the touch panel 2, and the second elastic wave sensors 112 of the plurality of elastic wave sensor units 11 all extend along the radial direction of the touch panel 2. As Figure 8 shown, the second elastic wave sensors 112 of the plurality of elastic wave sensor units 11 are all located on the side facing the center of the touch panel 2 of the first elastic wave sensor 111. That is, in each elastic wave sensor unit 11, the second elastic wave sensor 112 extends from the same side of the first elastic wave sensor 111 toward the center of the touch panel 2. This arrangement is preferably adopted when the elastic wave sensor unit 11 is arranged at the edge of the touch panel 2. Alternatively, as Figure 9As shown, the second elastic wave sensors 112 of the multiple elastic wave sensor units 11 are alternately located on one side of the first elastic wave sensor 111 facing the center of the touch panel 2 and on one side of the first elastic wave sensor 111 facing away from the center of the touch panel 2. For example, for one elastic wave sensor unit 11, the second elastic wave sensor 112 extends from the first side of the first elastic wave sensor 111 towards the center of the touch panel 2; while for an adjacent elastic wave sensor unit 11, the second elastic wave sensor 112 extends from the second side of the first elastic wave sensor 111 towards the side away from the center of the touch panel 2. This arrangement is preferably adopted when the elastic wave sensor unit 11 is arranged at a non-edge (such as the central area) of the touch panel 2.

[0053] It should be understood that the elastic wave sensor assembly 1 may be in other forms in addition to including the T-shaped elastic wave sensor units 11. For example, in some exemplary embodiments, such as Figures 3-4a , Figure 5 , Figure 6a and Figure 7 as shown, the elastic wave sensor assembly 1 includes a plurality of first elastic wave sensors 111 and does not include the second elastic wave sensors. Among them, as Figure 5 , Figure 6a and Figure 7 shown, the touch panel 2 may be rectangular or circular, and the plurality of first elastic wave sensors 111 may be arranged in sequence along the circumferential direction of the touch panel 2, and each first elastic wave sensor 111 may extend along the circumferential direction of the touch panel 2. Or, as Figure 3 and Figure 4a shown, the touch panel 2 is rectangular, and the plurality of first elastic wave sensors 111 may be arranged in sequence along the length direction of the touch panel 2, and each elastic wave sensor 111 may extend along the length direction of the touch panel 2.

[0054] In some exemplary embodiments, such as Figures 1-6bAs shown, the touch module 100 further includes a mounting substrate provided with a connection circuit. The elastic wave sensor assembly 1 is fixed to the mounting substrate and electrically connected to the connection circuit, and the mounting substrate is fixed to the back of the touch panel 2. The device supporting underwater touch operation further includes a control module, which is electrically connected to the connection circuit. The mounting substrate may be a flexible printed circuit board (FPC) 12, and the elastic wave sensor assembly 1 is fixed to the flexible printed circuit board 12 and electrically connected to the connection circuit of the flexible printed circuit board 12. The control module may include a printed circuit board 3, and the printed circuit board 3 includes an elastic wave algorithm. The elastic wave sensor in the elastic wave sensor assembly 11 is configured to detect an elastic wave signal caused by a touch action on the touch panel 2 and convert the elastic wave signal into an electrical signal. The printed circuit board 3 of the control module generates characteristic information about the touch panel 2 being touched according to the elastic wave algorithm, including at least one of position information, force information, and touch mode (or gesture) of the touch action.

[0055] Figure 10 The flowchart showing the working process of the touch module 100 is shown. After the underwater detection mode is turned on, the elastic wave sensor in the elastic wave sensor assembly 11 detects the elastic wave signal generated by the touch action. The touch chip of the control module processes the detected signal using the stored algorithm, and then generates characteristic information including at least one of position information, force information, and touch mode (or gesture) of the touch action.
