For example, the first pressure sensor module 130 and the second pressure sensor module 140 are respectively used to detect the pressure generated by the fingers (or hands) on both sides. Wherein, the first pressure sensor module 130 and the second pressure sensor module 140 may respectively include a plurality of pressure sensor units, the plurality of pressure sensor units are distributed at different positions of the handheld device, and the plurality of pressure sensor units are used to press the plurality of pressure sensors. The area (or touch point) is subjected to pressure detection, and according to the time sequence, the measured multiple pressure detection data are arranged in sequence to form a multi-dimensional pressure matrix to finely identify the user's posture and/or force distribution of holding the device.

Based on the content disclosed in the above embodiment, optionally, in this embodiment, the first pressure sensor module 130 includes three pressure sensor units, namely a first pressure sensor unit 131, a second pressure sensor unit 132, and a third pressure Sensor unit 133. FIG. 3 is a right side view of a handheld device. As shown in FIG. 3, the second pressure sensor module 140 includes three pressure sensor units, namely a fourth pressure sensor unit 141, a fifth pressure sensor unit 142, and a sixth pressure Sensor unit 143. The above 6 pressure sensor units are located in different touch areas.

The pressure signal processing circuit processes the 6 pressure signals into 6 pressure detections According to the chronological order, the processor module of the handheld device sequentially arranges the obtained 6 pressure detection data into a 3×2 matrix, or into a 2×3 matrix, instead of outputting single pressure detection data after averaging the two or other operations .

The number of pressure sensor units can be designed according to requirements, which is not limited in the embodiments of the present application.

The number and layout of pressure sensor units are not limited to those shown in the figure, and can also be combined in different combinations according to the structure of the handheld device. For example, four pressure sensor units are provided on the left side, and two pressure sensor units are provided on the right side, or vice versa. This embodiment of the present application does not limit this.

It should be understood that, in this embodiment, each pressure sensor module may include multiple pressure sensor units, a flexible circuit board, and an interface. Of course, the pressure sensor module may also include only one pressure sensing unit. For example, a pressure sensor module including only one pressure sensor unit may be provided on the upper right side of the handheld device.

It should be noted that FIG. 1-3 shows the pressure sensor module on the handheld device for the convenience of description. However, in reality, if the material of the outer frame or the casing of the handheld device is non-transparent, these pressure sensor modules The group is not visible externally. Of course, in the case of non-transparent materials, the housing can also be frosted at the position corresponding to the pressure sensor unit to provide a tactile feel different from the surrounding materials and enhance the user experience.

As shown in FIG. 4, it is a partial cross-sectional view of the handheld device shown in FIG. 1. Based on the content disclosed in the above embodiment, optionally, in this embodiment, the second pressure sensor module 140 is provided on the inner wall of the right side frame 160 of the handheld device in a conformable manner, specifically: the pressure sensor unit 141 passes The adhesive glue 1412 is attached to the inner wall of the right side frame 160 of the handheld device. The pressure sensor unit is connected to the flexible circuit board 1413, and the flexible circuit board 1413 is connected to the interface. For example, when a user shakes the device and applies an external force to the outer wall of the right side frame 160 of the handheld device, the right side frame 160 deforms, and the deformation signal is transmitted to the pressure sensor through the right side frame 160 of the handheld device and the adhesive 1412 Unit, the pressure sensor unit according to the force of the corresponding output can represent the pressure signal of the magnitude of the force. The pressure signal is transmitted to the pressure signal processing circuit through the flexible circuit board 1413 and the interface.

As another embodiment, as shown in FIG. 5, the second pressure sensor module is installed on the inner wall of the right side frame 260 of the handheld device, and the method is embedded. Specifically, the pressure sensor unit is installed in the high temperature injection molding method. The right side frame 260 of the handheld device is inside the frame material. The pressure sensor unit 231 is connected to the contact 262, and the pressure signal processing circuit is connected through the contact 262. For example, when an external force acts on the right side frame 260 of the handheld device, the deformation of the right side frame 260 will directly cause the deformation of the pressure sensor unit, and the pressure sensor unit outputs a pressure signal. The pressure signal is transmitted to the pressure signal processing circuit through the contact 262. The contact 262 is provided on the inner wall of the side frame of the handheld device by a fitting method and/or an embedding method.

Optionally, the manner in which the pressure sensor unit is provided on the inner wall of the left side frame and the inner wall of the right side frame of the handheld device may be a fitting type, an embedded type, or other methods, which is not limited in the embodiments of the present application.

The first pressure sensor subunit 331 and the second pressure sensor subunit 332 are connected to a contact 362, and the contact 362 is connected to a pressure signal processing circuit. The first pressure sensor subunit 331 and the second pressure sensor subunit 332 are located at the same position. Optionally, the pressure signals output by the two pressure sensor subunits can be superimposed at the same position, or the pressure signals output by multiple pressure sensor subunits can be superimposed at the same position. The superposition combination has higher sensitivity to pressure sensing . Specifically, when an external force acts on the right side frame 360 of the handheld device, the deformation of the side frame will simultaneously cause the deformation of the pressure sensor unit, and the pressure sensor unit outputs a pressure signal. At this time, the first pressure sensor unit 331 and the second pressure sensor unit 332 each output a pressure signal, and the output signal outputs a single value through averaging, median processing, or weighting processing as one of the data of the multi-dimensional pressure matrix . Compared with setting a single sensor unit at a single location, setting multiple sensor subunits at a single location can improve the pressure detection accuracy at that location, making it more sensitive to pressure sensing. One of the first pressure sensor unit 31, the second pressure sensor unit 132, the third pressure sensor unit 133, the fourth pressure sensor unit 141, the fifth pressure sensor unit 142, and the sixth pressure sensor unit 143 in the previous embodiment or The plurality or even all may have the same structure as the pressure sensor unit 330, that is, the pressure sensor units at different positions may include a plurality of pressure sensor subunits.

Of course, three or more pressure sensor units may be disposed in the side frame of the handheld device according to the combination method of fitting and embedding shown in FIG. 6. In this embodiment of the present application, the number of pressure sensor units is not limited.

Receive one or more pressure signals generated by the pressure sensor module 300 in time-sharing and convert the pressure signals into differential signals; for example, the multiplex switch 510 receives the first pressure sensor module (left panel) 300 and Two pressure signals generated by the second pressure sensor module (right side) 300. The input terminal of the pre-buffer 520 is connected to the output terminal of the multiplexing switch 510 to convert the differential signal into a single-ended signal; the input terminal of the high-precision analog-to-digital converter 530 is connected to the output terminal of the pre-buffer 520, Used to quantize single-ended signals to generate pressure detection data, even weak signals can be identified and quantified; the input of the handheld device processor module 310 is connected to the output of the high-precision analog-to-digital converter 530, which is used to The pressure detection data input from the analog-to-digital converter 530 generates a multi-dimensional pressure matrix and analyzes it, thereby starting a preset function. Specifically, after the pressure sensor module 300 senses the pressure deformation, the first pressure sensor module and the second pressure sensor module output the pressure signal of each pressure sensor unit, and the multiplex switch 510 resists the deformation The change of the value or the capacity value converts the pressure signal into a differential voltage signal and sends it to the pre-buffer 520. The differential voltage signal is converted into a single-ended voltage signal through the pre-buffer 520 and then quantized by a high-precision analog-to-digital converter 530 , Generate pressure detection data, and then send it to the handheld device processor module 310. The multiplex switch can support multiple external input pressure signals, so that multiple signals share the same hardware processing circuit, simplifying the circuit structure of the subsequent stage. The high-precision analog-to-digital converter can identify weak signals and quantize the signals, so that there is no need to add analog-to-digital converters and amplifiers in the circuit, saving circuit resources.

Optionally, in the embodiment of the present application, the multiplexer switch may be connected to two pressure sensor modules, or may be one or more pressure sensor modules, which is not limited in the embodiment of the present application.

An example is to arrange 9 pressure detection data into a 3×3 matrix, that is, to generate a multi-dimensional pressure matrix

The arrangement of the multi-dimensional pressure matrix depends on the amount of pressure detection data.

After comparison, a state matrix is obtained, and the handheld device processor module 310 generates corresponding function feedback according to the state matrix. For example, the multi-dimensional pressure matrix is

The threshold matrix is

The first fixed value can be 1, and the second fixed value can be 0. According to the order of the matrix, compare the pressure detection data 2, 6, 1, 3, 5, 2, 1, 3, 2 with the pressure threshold of the threshold matrix 5, 1, 2, 6, 3, 1, 2, 2. 1. If the pressure detection data is greater than the pressure threshold, set the value of the status matrix to 1.
