[0033] At present, the application of voice recognition and voice processing technology in the field of human-computer interaction has become a very common application method. Voice recognition and voice processing technology has become an indispensable part of daily life. Voice recognition and voice processing technology is often used in intelligent customer service, digital humans, voiceprint recognition and other fields.

[0034] However, in the existing sound recognition and sound processing technologies, the sound signal recognized by the recognition module 2 is easily mixed with the noise in the environment, making it extremely difficult for the recognition module 2 to recognize the voiceprint in a noisy environment. The accuracy of the recognition module 2 in recognizing the voiceprint is low, which seriously affects the promotion of the technology and products.

[0035] The invention provides a touch screen structure.

[0036] See also Figure 1 In one embodiment of the present invention, the touch screen structure comprises a touch screen glass 1; and

[0037] An identification module 2, the identification module 2 comprising an infrared touch panel 21 and a sensor 22, the sensor 22 being electrically connected to the infrared touch panel 21, and the sensor 22 being used to be directly or indirectly connected to the touch screen glass 1;

[0038] The touch screen glass 1 is used to generate a vibration signal, the sensor 22 is used to receive the vibration signal and transmit the vibration signal to the infrared touch panel 21, and the infrared touch panel 21 is used to identify the type of contact object that generates the vibration signal according to the vibration signal;

[0039] The technical solution of the present invention adopts an electrical connection between the sensor 22 and the infrared touch panel 21, and sets the sensor 22 to be directly or indirectly connected to the touch screen glass 1, so that the vibration signal generated when the touch screen glass 1 is touched by the contact object can be directly or indirectly detected and received by the sensor 22, thereby avoiding the transmission of other sounds other than glass sounds such as noise in the air to the sensor 22, thereby improving the clarity of the data collected by the sensor 22, and further improving the accuracy of the infrared touch panel 21 in identifying the type of contact object on the touch screen glass 1.

[0040] In this embodiment, the touch screen glass 1 can be a display screen with a touch function, and the touch screen glass 1 is used to generate a vibration signal by touching the touch screen glass 1 with a contact object. The sensor 22 can be a vibration sensor such as a bone conduction microphone. The detection frequency range of the sensor 22 can be 20 to 20,000 Hz. By using a vibration sensor to detect the vibration signal generated by the touch screen glass 1, the existing microphone is replaced to detect air vibration, thereby avoiding sound interference in the air. The infrared touch panel 21 is electrically connected to the sensor 22, so that the sensor 22 can transmit the received vibration signal to the infrared touch panel 21, so that the infrared touch panel 21 can identify the category of the contact object that generates the vibration signal according to the vibration signal. The sensor 22 can be attached to the touch screen glass 1 by solid glue, so that the sensor 22 is directly connected to the touch screen glass 1. Since the touch screen glass 1 is connected to the sensor 22 only by solid glue, the sensor 22 can directly detect and receive the vibration signal generated by the touch screen glass 1, which can not only isolate the noise in the air and other sounds not emitted by the glass from being transmitted to the sensor 22, but also make the sensor 22 only receive the vibration signal generated by the touch screen glass 1, thereby improving the accuracy of the data collected by the sensor 22.

[0041] In this embodiment, the infrared touch panel 21 can be mounted on a fixing bracket 3 for fixing the touch screen glass 1, and the sensor 22 can be mounted on the infrared touch panel 21. The infrared touch panel 21 can be connected to the touch screen glass 1 through a solid medium, so that the sensor 22 is indirectly connected to the touch screen glass 1. Therefore, when the touch screen glass 1 generates a vibration signal, it can drive the infrared touch panel 21 to vibrate synchronously, that is, the touch screen glass 1 transmits the vibration signal to the infrared touch panel 21, and at the same time, the sensor 22 detects the vibration of the infrared touch panel 21 and receives the vibration signal, and the sensor 22 transmits the vibration signal to the infrared touch panel 21 to complete the subsequent recognition work. Since the touch screen glass 1 is only connected to the infrared touch panel 21 through a solid medium, the sensor 22 only receives the vibration signal generated from the touch screen glass 1, thereby isolating the noise in the air and other sounds not emitted by the glass from being transmitted to the sensor 22, thereby improving the accuracy of the data collected by the sensor 22, and thereby improving the accuracy of the infrared touch panel 21 in identifying the type of contact object on the touch screen glass 1.

[0042] like Figure 1 , Figure 6 and Figure 8 As shown, in this embodiment, the touch screen structure also includes a fixed bracket 3 and a sound transmitting connector 4, the touch screen glass 1 is connected to the fixed bracket 3, the infrared touch panel 21 is arranged in the fixed bracket 3, the infrared touch panel 21 is connected to the touch screen glass 1 through the sound transmitting connector 4, and the sensor 22 is arranged on the infrared touch panel 21.

[0043] In this embodiment, the fixing bracket 3 can be a quadrilateral frame, so that the touch screen glass 1 is fixed in the frame, and an infrared touch panel 21 can be installed on one side of the frame. By fixing the touch screen glass 1 and the infrared touch panel 21 on the fixing bracket 3, it is prevented that the touch screen glass 1 and the infrared touch panel 21 shake and generate vibration signals by mistake, so that the recognition module 2 performs erroneous recognition. In order to facilitate the transmission of the vibration signal generated by the touch screen glass 1 to the recognition module 2, the infrared touch panel 21 is connected to the touch screen glass 1 through the sound transmission connector 4, and the sound transmission connector 4 is used to transmit the vibration signal generated by the touch screen glass 1 to the infrared touch panel 21, thereby driving the infrared touch panel 21 to vibrate, and then the sensor 22 detects and receives the vibration signal, and transmits the vibration signal to the infrared touch panel 21 through the sensor 22. The infrared touch panel 21 identifies the type of contact object that generates the vibration signal according to the vibration signal.

[0044] like Figure 1 , Figure 6 and Figure 8As shown, in this embodiment, the sound transmission connector 4 is arranged in the fixed bracket 3, the two ends of the sound transmission connector 4 are respectively connected to the infrared touch panel 21 and the touch screen glass 1, and the sensor 22 is arranged on the side of the infrared touch panel 21 away from the sound transmission connector 4.

[0045] In this embodiment, the sound transmission connector 4 can be set as a plastic column. By setting the sound transmission connector 4 as a solid medium for transmitting vibration signals between the touch screen glass 1 and the infrared touch panel 21, the vibration signal generated by the touch screen glass 1 can be transmitted to the infrared touch panel 21 through the sound transmission connector 4. By indirectly connecting the sensor 22 to the touch screen glass 1, the vibration signal generated by the touch screen glass 1 is transmitted to the infrared touch panel 21 through the sound transmission connector 4, so that the sensor 22 only receives the vibration signal generated by the touch screen glass 1, thereby isolating the noise in the air and other environmental noises not emitted by the glass from being transmitted to the sensor 22, thereby preventing the recognition module 2 from being affected by the environmental noise in the environment, thereby improving the clarity of the data collected by the sensor 22, and thereby improving the accuracy of the infrared touch panel 21 in identifying the type of contact object on the touch screen glass 1.

[0046] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the fixing bracket 3 includes a first side wall 31 and a second side wall 32 that are relatively spaced apart, a receiving cavity 33 is formed between the first side wall 31 and the second side wall 32 , and the infrared touch panel 21 is disposed in the receiving cavity 33 .

[0047] In this embodiment, in order to facilitate the installation of the infrared touch panel 21 in the fixed bracket 3 and improve the connection stability between the infrared touch panel 21 and the fixed bracket 3, the infrared touch panel 21 is disposed in the accommodating cavity 33, so that the accommodating cavity 33 provides protection for the infrared touch panel 21, so that the infrared touch panel 21 can be stably installed in the fixed bracket 3, thereby preventing the infrared touch panel 21 from erroneously generating a vibration signal due to accidental large shaking, thereby affecting the normal operation of the identification module 2.

[0048] like Figures 1 to 5 As shown, in this embodiment, the sound transmitting connector 4 includes a main body 41, a first contact arm 42 and a second contact arm 43 spaced apart from the main body 41, the first contact arm 42 is connected to the touch screen glass 1, the first side wall 31 has a notch 311 connected to the accommodating cavity 33, and the second contact arm 43 passes through the notch 311 to connect to the infrared touch panel 21.

[0049] In this embodiment, in order to facilitate the acoustic connector 4 to transmit the vibration signal on the touch screen glass 1 to the infrared touch panel 21, the acoustic connector 4 abuts the touch screen glass 1 and the infrared touch panel 21 through the first contact arm 42 and the second contact arm 43, respectively, so that the vibration signal generated on the touch screen glass 1 is transmitted to the infrared touch panel 21 through the first contact arm 42 and the second contact arm 43, so that the infrared touch panel 21 vibrates, thereby facilitating the sensor 22 to detect the vibration signal. In order to facilitate the second contact arm 43 to abut the infrared touch panel 21, the first side wall 31 is provided with a notch 311 connected to the accommodating cavity 33, so that the second contact arm 43 can pass through the notch 311 to abut the infrared touch panel 21.

[0050] In this embodiment, in order to improve the stability of the connection between the sound transmitting connector 4 and the first side wall 31, the sound transmitting connector 4 can be attached to the edge of the first side wall 31 close to the notch 311 by fasteners such as screws, so that the sound transmitting connector 4 is stably fixed on the first side wall 31, thereby enabling the sound transmitting connector 4 to better transmit the vibration signal.

[0051] like Figure 2 As shown, in this embodiment, the first contact arm 42 includes a first connecting section 421 and a first contact end 422 that are interconnected, the first contact end 422 has a first contact plane 4221, and the first contact end 422 abuts the touch screen glass 1 through the first contact plane 4221; the second contact arm 43 includes a second connecting section 431 and a second contact end 432 that are interconnected, the second contact end 432 has a second contact plane 4321, and the second contact end 432 abuts the infrared touch panel 21 through the second contact plane 4321.

[0052] In this embodiment, in order to make the first contact arm 42 better fit the touch screen glass 1, the first contact end 422 is set to abut the touch screen glass 1 through the first contact plane 4221, thereby increasing the contact area between the first contact arm 42 and the touch screen glass 1, thereby increasing the efficiency of the first contact arm 42 in transmitting the vibration signal, and further increasing the efficiency of the identification module 2 in identifying the type of the contact object. Similarly, in order to make the second contact arm 43 better fit the infrared touch pad 21, the second contact end 432 is set to abut the infrared touch pad 21 through the second contact plane 4321, thereby increasing the contact area between the second contact arm 43 and the infrared touch pad 21, thereby increasing the efficiency of the second contact arm 43 in transmitting the vibration signal to the infrared touch pad 21, so that the sensor 22 quickly detects and receives the vibration signal and the infrared touch pad 21 quickly receives and identifies the vibration signal, thereby increasing the efficiency of the identification module 2 in identifying the type of the contact object.

[0053] like Figure 1 and Figure 2As shown, in this embodiment, the first side wall 31 and the second side wall 32 are oppositely provided with grooves 34 , and both sides of the infrared touch panel 21 are inserted into the grooves 34 on the first side wall 31 and the second side wall 32 .

[0054] In this embodiment, in order to further improve the stability of the infrared touch panel 21 connected to the first side wall 31 and the second side wall 32 respectively, the two side edges of the infrared touch panel 21 are inserted into the grooves 34 on the first side wall 31 and the second side wall 32, so that the infrared touch panel 21 can be stably installed in the fixed bracket 3, thereby preventing the infrared touch panel 21 from erroneously generating a vibration signal due to accidental large shaking, thereby affecting the normal operation of the identification module 2.

[0055] like Figure 7 As shown, in this embodiment, the touch screen structure further includes a connector 5 , the sensor 22 is disposed on the touch screen glass 1 , and the sensor 22 is connected to the infrared touch panel 21 via the connector 5 .

[0056] In this embodiment, the sensor 22 can also be directly attached to the touch screen glass 1 by solid glue. The sensor 22 is directly connected to the touch screen glass 1, so that the vibration signals generated by the touch screen glass 1 are all received by the sensor 22 and transmitted to the infrared touch panel 21, which can not only isolate the noise in the air and other sounds not emitted by the glass from being transmitted to the sensor 22, but also make the sensor 22 only receive the vibration signals generated by the touch screen glass 1, thereby improving the clarity of the data collected by the sensor 22. The connector 5 can be a wire, a flexible flat cable or other wire for transmitting signals. In order to facilitate the sensor 22 to transmit the vibration signal to the infrared touch panel 21, the connector 5 is provided to connect the sensor 22 and the infrared touch panel 21, so that the vibration signal received by the sensor 22 is transmitted to the infrared touch panel 21 via the connector 5.

[0058] In this embodiment, by limiting the connecting member 5 to a connecting cable, the sensor 22 is electrically connected to the infrared touch panel 21 through the connecting member 5.
