[0033] Currently, it is a very common application mode to apply sound recognition and sound processing technology in the field of human-computer interaction. Sound recognition and sound processing technology has become an indispensable part of daily life, and is commonly used in intelligent customer service, digital people, voiceprint recognition and other fields.

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

[0035] The present application provides a touch screen structure.

[0036] Please refer to FIG. 1, in an embodiment of the present application, the touch screen structure includes a touch screen glass 1 and a recognition module 2.

[0037] The recognition module 2 comprises an infrared touchpad 21 and a sensor 22, the sensor 22 and the infrared touchpad 21 are electrically connected, and the sensor 22 is used for being directly or indirectly connected with the touch screen glass 1.

[0038] The touch screen glass 1 is used for forming a vibration signal, the sensor 22 is used for receiving the vibration signal and transmitting the vibration signal to the infrared touchpad 21, and the infrared touchpad 21 is used for recognizing the category of the contact according to the vibration signal.

[0039] The technical scheme of the present application adopts the electric connection between the sensor 22 and the infrared touchpad 21, directly or indirectly connects the sensor 22 with the touch screen glass 1, so that the vibration signal formed after the touch screen glass 1 is touched by the contact can be directly or indirectly detected and received by the sensor 22, thereby avoiding the transmission of noise in the air and other sounds emitted by non-glass into the sensor 22, and improving the clarity of the data collected by the sensor 22, and improving the accuracy of the infrared touchpad 21 in recognizing the category of the contact on the touch screen glass 1.

[0040] In the embodiment, the touch screen glass 1 can be a display screen with a touch function, and the touch screen glass 1 is used for generating a vibration signal by touching the touch screen glass 1 by the contact. The sensor 22 can be a bone conduction microphone or other vibration sensor, and the detection frequency range of the sensor 22 can be 20 to 20000 Hz. The infrared touchpad 21 is electrically connected with the sensor 22, so that the sensor 22 can transmit the received vibration signal to the infrared touchpad 21, and the infrared touchpad 21 can recognize the category of the contact according to the vibration signal. The sensor 22 can be pasted on the touch screen glass 1 by solid glue, so that the sensor 22 is directly connected with the touch screen glass 1. Since the touch screen glass 1 is connected with 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 not only isolates the transmission of noise in the air and other sounds emitted by non-glass into the sensor 22, but also makes 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 the embodiment, the infrared touchpad 21 can be installed on the fixing support 3 for fixing the touch screen glass 1, and the sensor 22 can be installed on the infrared touchpad 21. The infrared touchpad 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, the infrared touchpad 21 can be synchronously vibrated, that is, the touch screen glass 1 transmits the vibration signal to the infrared touchpad 21. At the same time, the sensor 22 detects the vibration of the infrared touchpad 21 and receives the vibration signal. The sensor 22 transmits the vibration signal to the infrared touchpad 21 to complete the subsequent identification work. Since the touch screen glass 1 is connected to the infrared touchpad 21 through a solid medium, the sensor 22 only receives the vibration signal generated by the touch screen glass 1. Therefore, other sounds emitted by non-glass in the air, such as noise, are isolated from being transmitted to the sensor 22. Therefore, the accuracy of the data collected by the sensor 22 is improved, and the accuracy of the infrared touchpad 21 in identifying the category of the contact on the touch screen glass 1 is improved.

[0042] As shown in FIGS. 1, 6 and 8, in the embodiment, the touch screen structure further includes a fixing support 3 and an acoustic connection piece 4. The touch screen glass 1 is connected to the fixing support 3. The infrared touchpad 21 is arranged in the fixing support 3.

[0043] In the embodiment, the fixing support 3 can be a quadrilateral frame. The touch screen glass 1 is fixed in the frame. One side of the frame can be provided with the infrared touchpad 21. By fixing the touch screen glass 1 and the infrared touchpad 21 on the fixing support 3, the touch screen glass 1 and the infrared touchpad 21 are prevented from shaking and generating false vibration signals, so that the identification module 2 performs false identification work. In order to facilitate the transmission of the vibration signal generated by the touch screen glass 1 to the identification module 2, the infrared touchpad 21 is connected to the touch screen glass 1 through the acoustic connection piece 4. The acoustic connection piece 4 is used to transmit the vibration signal generated by the touch screen glass 1 to the infrared touchpad 21, so as to vibrate the infrared touchpad 21. The sensor 22 detects and receives the vibration signal. The sensor 22 transmits the vibration signal to the infrared touchpad 21. The infrared touchpad 21 identifies the category of the contact according to the vibration signal.

The sound transmission connecting piece 4 is arranged as a solid medium for transmitting the vibration signal between the touch screen glass 1 and the infrared touch panel 21, so that the vibration signal generated by the touch screen glass 1 can be transmitted to the infrared touch panel 21 through the sound transmission connecting piece 4. The sensor 22 is indirectly connected with the touch screen glass 1, so that the vibration signal generated by the touch screen glass 1 is transmitted to the infrared touch panel 21 through the sound transmission connecting piece 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 noise from the glass from being transmitted to the sensor 22, thereby avoiding the influence of the environmental noise in the environment on the identification module 2, 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 category of the contact on the touch screen glass 1.

In order to facilitate the second contact arm 43 to abut against the infrared touchpad 21, the first side wall 31 is provided with a gap 311 communicating with the accommodating cavity 33, so that the second contact arm 43 can pass through the gap 311 to abut against the infrared touchpad 21.

[0052] In the embodiment, in order to better attach the first contact arm 42 to the touch screen glass 1, the first contact end 422 is arranged to abut against 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, improving the efficiency of the first contact arm 42 in transmitting the vibration signal, and further improving the efficiency of the identification module 2 in identifying the category of the contact object. Similarly, in order to better attach the second contact arm 43 to the infrared touchpad 21, the second contact end 432 is arranged to abut against the infrared touchpad 21 through the second contact plane 4321, thereby increasing the contact area between the second contact arm 43 and the infrared touchpad 21, improving the efficiency of the second contact arm 43 in transmitting the vibration signal to the infrared touchpad 21, so that the sensor 22 can quickly detect and receive the vibration signal, and the infrared touchpad 21 can quickly receive and identify the vibration signal, thereby improving the efficiency of the identification module 2 in identifying the category of the contact object.
