[0008] By adopting the above technical solution, the microcontroller, as the core control unit in the main control module, is equipped with multiple pins, which facilitates connection with the sound pickup module, display module, vibration module and power supply, avoids timing conflicts caused by single pin multiplexing, and improves signal real-time performance.
[0009] As a further technical solution, the power supply includes a 2V interface and a 5V interface, and the 5V pin is connected to the 5V interface.
[0010] By adopting the above technical solution, the power supply is equipped with different voltage interfaces to meet the voltage requirements of different electronic components.
[0011] As a further technical solution, the sound pickup module includes a condenser microphone module, which includes a Grounded pin, a +Vs pin, and an Output pin. The Output pin is connected to the PA1 pin, and the +Vs pin is connected to the 2V interface.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. The library uses a noise reminder table mat. It employs a sound pickup module to collect sound decibels, and the main control module controls the vibration module to vibrate, so that readers feel the vibration at the point of contact with the table mat and receive a reminder. At the same time, this vibration is automatically started and stopped through the sound decibel threshold setting in the main control module.

[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] In public spaces, libraries are the first choice for people to study and read, and the quiet environment is a major attraction. However, libraries have noise problems, and relying solely on library staff to remind people to reduce noise is too cumbersome, affecting the efficiency and quality of their library management work.
[0027] Therefore, a noise-reminder table mat for libraries is proposed to solve the above problems.
[0028] like Figure 1-6 As shown, the specific solution of the embodiment is as follows: A noise reminder table mat for a library includes a table mat and functional components disposed on the table mat. The functional components include a main control module 1, a sound pickup module 2, a display module 3, a vibration module 4, and a power supply 5. The main control module 1 is connected to the sound pickup module 2, the display module 3, and the vibration module 4 respectively. The main control module 1 is used to collect sound decibels by the sound pickup module 2 to control the vibration of the vibration module 4, and the sound decibels are displayed by the display module 3. The power supply 5 is used to supply power to the main control module 1, the sound pickup module 2, and the display module 3.
[0029] Specifically, the main control module 1 collects noise and feeds back signals through the sound pickup module 2. The main control module 1 is set with a sound decibel threshold. When the sound exceeds the preset threshold, the main control module 1 controls the vibration module 4 to vibrate. When the sound is below the preset threshold, the main control module 1 controls the vibration module 4 to stop vibrating.
[0030] Among them, the display module 3 communicates with the main control module 1 through the UART method. UART, or Universal Asynchronous Receiver / Transmitter, is a commonly used serial communication protocol that is widely used in data exchange between embedded systems, microcontrollers, and computers. It adopts an asynchronous serial communication method, that is, the sending end and the receiving end do not need to be active at the same time. Instead, the start and stop bits are used to identify the start and end of the data frame.
[0031] It should be noted that the table mats are not limited to use in libraries; in practical applications, they can also be used in public spaces such as study rooms and office areas.
[0032] In this embodiment, the main control module 1 includes a microcontroller, which includes a GND pin, a 5V pin, a PA1 pin, a PA2 pin, a PA9 pin, and a PA10 pin.
[0033] The main control module 1 uses an STM32F103 microcontroller, which is grounded on its GND pin. It has the advantages of high stability and low price. The appropriate model can be selected according to the actual situation in actual use.
[0034] In this embodiment, the power supply 5 includes a 2V interface and a 5V interface, with the 5V pin connected to the 5V interface.
[0035] It should be noted that the power supply 5 includes a charging management chip that supports multiple outputs and can simultaneously provide 2V and 5V interfaces, resulting in high integration. It is suitable for use on desk mats and meets the voltage requirements of different electronic components.
[0036] In this embodiment, the pickup module 2 includes a condenser microphone module, which includes a Grounded pin, a +Vs pin, and an Output pin. The Output pin is connected to the PA1 pin, and the +Vs pin is connected to the 2V interface.
[0037] The condenser microphone module is the RMIC-110-5-4015-NS3 condenser microphone, with a grounded pin. It has a diameter of 4.00mm, a height of 1.70mm, and is unidirectional. It is terminated with a wire lead. It has the advantages of small size, high sensitivity, good directionality, low price, and easy integration.
[0038] Specifically, the sound pickup module 2 is mainly used to collect the decibel level of sound on one side of the table and output it to the main control module 1 in the form of a level.
[0039] In this embodiment, the vibration module 4 includes a vibration motor module, which includes a positive pin and a negative pin. The positive pin is connected to the PA2 pin, and the main control module 1 outputs a signal through the PA2 pin to the positive pin to control the vibration of the vibration motor module.
[0040] It should be noted that the vibration motor module is a transverse linear motor, a vibration device that drives the mover to move laterally through electromagnetic induction. It has low noise and crisp feedback during vibration. The transverse linear motor requires a high-level trigger and its negative pin is grounded during use.
[0041] Specifically, the main control module 1 applies a 3.3V PWM wave through the PA2 pin to control the vibration motor module to vibrate, and also provides power for the vibration motor module to vibrate.
[0042] In this embodiment, the display module 3 includes a smart screen, which includes a TX pin, an RX pin, a VCC pin, and a GND pin. The TX pin is connected to the PA10 pin, the RX pin is connected to the PA9 pin, and the VCC pin is connected to the 5V interface.
[0043] Among them, the intelligent one is the TJC3224T124 series 2.4-inch OLED serial port intelligent screen, which has the advantages of high resolution and high brightness, and lower power consumption compared to LCD monitors.
[0044] Specifically, the display module 3 can display the decibel level of the sound collected by the sound pickup module 2 in real time while the vibration occurs to remind the person making the noise, and the vibration module 4 keeps the screen off when the vibration stops to save power.
[0045] In addition, the VCC pin voltage is fixed at +5V and connected to the 5V power supply interface to ensure a stable power supply for the smart screen.
[0046] In this embodiment, the main control module 1 and the sound pickup module 2 are located on the side of the table mat, the vibration module 4 and the power supply 5 are located on the bottom surface of the table mat, and the display module 3 is located on the top surface of the table mat. The table mat is L-shaped and covers the top surface and one side of the table.
[0047] Specifically, the main control module 1 and the sound pickup module 2 are located on the side of the table mat, allowing users to easily adjust them via the main control module 1. The sound pickup module 2 can also directly record the decibel level of the person making the noise, improving the accuracy of the sound pickup module 2. The vibration module 4 and the power supply 5 are located on the bottom of the table mat, without directly contacting the user. Placing the modules here avoids damaging the flatness of the desktop and maintains a clean appearance. In addition, when the vibration module 4 is in close contact with the desktop, the vibration can be efficiently transmitted to the entire table mat through the hard surface, enhancing the feedback intensity and consistency.
[0048] The working principle of the above embodiments is as follows: In public places, when users place their hands on the table mat surface, and noise is emitted by the user or those nearby, the sound pickup module 2 uses a condenser microphone module to collect the sound decibels within a certain range. The sound decibel data signal is then transmitted to the microcontroller via the Output pin. The built-in ADC is used to obtain the level value of the PA1 pin, which is then converted to obtain the decibel value. The microcontroller determines whether the decibel value exceeds a preset threshold. If it does, the microcontroller applies a 3.3V PWM wave via the PA2 pin to control the vibration motor module to vibrate. At the same time, the decibel value signal is transmitted to the OLED serial port smart screen for display, serving to remind the user or prompt the user to remind those around them to lower their conversation volume.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
