[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0042] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0043] Currently, the product includes voice-activated wallpapers designed specifically for children's learning environments. By combining touch technology with audio playback, children can simply press on the patterns on the wallpaper to hear corresponding audio content, such as animal sounds, English words, or nursery rhymes. This interactive learning method not only stimulates children's interest in learning but also effectively improves their cognitive and language expression abilities.

[0044] However, this type of voice wallpaper requires children to trigger it themselves to output corresponding voice content. If it is not triggered, the voice wallpaper will not output any voice content, resulting in a weak learning atmosphere.

[0045] Therefore, refer to Figure 1 and Figure 2 To address the aforementioned problems, this utility model proposes a voice-learning wallpaper, which includes:

[0046] Wallpaper itself;

[0047] Main control module 10, wherein the main control module 10 is disposed within the wallpaper body;

[0048] Multiple infrared phototransistor modules 20 are respectively disposed on the surface of the wallpaper body; the output terminal of the infrared phototransistor module 20 is electrically connected to the main control module 10; the infrared phototransistor module 20 is used to output an infrared detection signal when a human body is detected within a preset range;

[0049] Voice output module 30, wherein the voice output module 30 is disposed on the surface of the wallpaper body;

[0050] The main control module 10 is used to control the voice output module 30 to be in a working state or in a stopped state based on receiving at least one infrared detection signal.

[0051] In this embodiment, the learning content on the wallpaper can be set according to actual needs, i.e., areas triggered by pressing. For example, according to the user's actual learning needs, each learning area corresponds to different learning content, such as multiplication tables, Chinese pinyin, English words, etc.

[0052] In this embodiment, the main control module 10 can be implemented using FPGA (Field Programmable Gate Array), PLC (Programmable Logic Controller), MCU (Microcontroller Unit), DSP (Digital Signal Processor), SOC (System On Chip), etc.

[0053] In this embodiment, multiple infrared transducer modules 20 can be implemented using multiple infrared sensors of the same specifications. All infrared transducer modules 20 are disposed on the surface of the wallpaper body, thereby effectively detecting the presence of a target within a preset range. It should be noted that the voice-learning wallpaper is primarily designed for children in the early stages of learning. Therefore, triggering the voice-learning wallpaper requires effective confirmation of whether the target entering the preset range is an adult or a child. By adjusting the detection directions of the multiple infrared transducer modules 20 accordingly, the heights that different infrared transducer modules 20 can detect are different. This allows for the determination of whether the target entering the preset range is an adult or a child by detecting the height of the target, thereby determining whether a voice control signal needs to be output to the voice control module.

[0054] Optionally, the plurality of infrared phototransistor modules 20 include:

[0055] The first infrared photodiode module 21 is disposed on the surface of the wallpaper body, and the detection direction of the first infrared photodiode module 21 is a horizontal downward first detection direction; the first infrared photodiode module 21 is electrically connected to the main control module 10; the first infrared photodiode module 21 is used to detect the target to be tested in the first direction and output a first infrared detection signal;

[0056] The second infrared photodiode module 22 is disposed on the surface of the wallpaper body, and the detection direction of the second infrared photodiode module 22 is a second detection direction in the horizontal direction; the second infrared photodiode module 22 is electrically connected to the main control module 10; the second infrared photodiode module 22 is used to detect the target to be tested in the second direction and output a second infrared detection signal;

[0057] The third infrared transducer module 23 is disposed on the surface of the wallpaper body, and the detection direction of the third infrared transducer module 23 is a horizontal upward third detection direction; the third infrared transducer module 23 is electrically connected to the main control module 10; the third infrared transducer module 23 is used to detect the target in the third direction and output a third infrared detection signal.

[0058] In this embodiment, the multiple infrared transceiver modules 20 include a first infrared transceiver module 21, a second infrared transceiver module 22, and a third infrared transceiver module 23. These modules are all disposed on the surface of the wallpaper body, but their detection angles differ, enabling detection at different heights. It is understood that when a target is present among the multiple infrared transceiver modules 20, the first infrared transceiver module 21 will detect the corresponding first infrared detection signal. Furthermore, based on the height at which the wallpaper is installed using voice learning, it can be further confirmed whether the second infrared detection signal output by the second infrared transceiver module 22 indicates that the target is a child or an adult. The detection by the third infrared transceiver module 23 can effectively determine whether the target within a preset area is an adult. For example, if the main control module 10 receives the first infrared detection signal output by the first infrared transducer module 21 and confirms the presence of a target in the first detection direction, and the second infrared detection signal output by the second infrared transducer module 22 confirms the absence of a target in the second detection direction, then the target can be confirmed as a child. If the main control module 10 receives the first infrared detection signal output by the first infrared transducer module 21 and confirms the presence of a target in the first detection direction, and the second infrared detection signal output by the second infrared transducer module 22 confirms the presence of a target in the second detection direction, then further confirmation is needed based on the set height of the wallpaper body. Therefore, the second infrared detection signal output by the second infrared transducer module 22 can be switched according to the infrared state switching signal. When the wallpaper body is set at a low height, if the second infrared detection signal output by the second infrared transducer module 22 detects a target in the second detection direction, then the target is still confirmed as a child. When the wallpaper body is set at a high height, if the second infrared detection signal output by the second infrared transducer module 22 detects a target in the second detection direction, then further judgment is made using the third infrared detection signal.

[0059] Optionally, the voice learning wallpaper includes an infrared state switching module 40, which is disposed on the surface of the wallpaper body, and the output terminal of the infrared state switching module 40 is electrically connected to the main control module 10; the infrared state switching module 40 is used to output an infrared state switching signal when triggered.

[0060] The main control module 10 is used to receive the infrared state switching signal and switch the detection state of the second infrared detection signal.

[0061] In this embodiment, the infrared state switching module 40 can be implemented using buttons, knobs, virtual buttons, touchscreens, toggle switches, etc., combined with corresponding circuits. Users can effectively switch the state of the second infrared detection signal output by the second infrared detection circuit through the infrared state switching module 40, thereby addressing the issue of inconsistent wallpaper height settings and effectively improving the flexibility of voice-learning wallpapers.

[0062] In this embodiment, the voice output module 30 can be implemented using a voice chip and a speaker. The voice output module 30 receives the voice control signal output by the main control module 10, and then outputs the corresponding voice signal. The voice control signal output by the main control module 10 can be based on multiple corresponding infrared detection signals, or it can be based on a button trigger signal output by the button trigger module.

[0063] By employing a voice-activated learning wallpaper, the usability of the wallpaper is effectively improved. The voice-activated learning wallpaper includes a wallpaper body, a main control module 10, multiple infrared photocell modules 20, and a voice output module 30. It is understood that the voice-activated learning wallpaper can detect whether a person of a corresponding height has entered within a preset range using the multiple infrared photocell modules 20. When the multiple infrared photocell modules 20 are detecting, the main control module 10 confirms the presence of a person of the corresponding height within the preset range based on the corresponding infrared detection signals, and then outputs a corresponding voice control signal to the voice control module, which in turn outputs a corresponding voice signal to the voice output module 30. The voice signal output by the voice output module 30 can be controlled according to a preset program in the main control module 10 to output the corresponding voice signal, thus enabling the voice-activated learning wallpaper to be triggered without pressing, effectively enhancing the learning atmosphere created by the wallpaper.

[0064] refer to Figure 2 In one embodiment of the present invention, the voice learning wallpaper further includes a human body sensing module 50, which is disposed on the surface of the wallpaper body and the detection direction of the human body sensing module 50 is a first detection direction of horizontal downward; the human body sensing module 50 is used to detect the target to be tested within a preset range and output a human body sensing signal.

[0065] The main control module 10 is used to output multiple corresponding infrared detection switch signals to multiple infrared phototransistor modules 20 according to the human body sensing signal, so as to adjust the working state of the multiple infrared phototransistor modules 20.

[0066] In this embodiment, having multiple infrared photodiode modules 20 continuously operational would result in high power consumption. Therefore, a human body sensing module 50 detects the presence of a target within a preset range, thereby controlling whether the multiple infrared photodiode modules 20 need to operate. The human body sensing module 50 can be implemented using a PIR sensor or a thermopile sensor, placed on the surface of the wallpaper body to detect within the preset range. It is important to note that the detection range of the human body sensing module 50 must correspond to the detection range of the multiple infrared photodiode modules 20. This ensures that after the human body sensing module 50 detects a target, the main control module 10 can control the multiple infrared photodiode modules 20 to operate, thus achieving detection within the preset range.

[0067] refer to Figures 2 to 4 In one embodiment of this utility model, the voice learning wallpaper further includes a power module 60, the input terminal of the power module 60 is electrically connected to a power input terminal, and the output terminal of the power module 60 is electrically connected to the main control module 10; the power module 60 is used to convert the first voltage input to the power input terminal into a second voltage and output it.

It is understood that overcharging a battery can lead to increased internal pressure and temperature, and in severe cases, even explosion or fire. The charging protection circuit monitors the battery voltage and cuts off the charging current when it reaches a safe upper limit, thereby preventing overcharging.

[0077] In this embodiment, the first LED D1 and the second LED D2 serve as a prompting circuit to indicate to the user whether the voice learning wallpaper is currently charging or not. The charging protection chip can be implemented using a TP4056 to protect the battery during charging.
