[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-9 , the present utility model provides a technical solution: a voice fan, including a radiator body and an infrared remote control module, a fan control module, a voice collection module, a data processing module, and a display module installed inside the radiator body. The data processing module is electrically connected to the infrared remote control module, the fan control module, and the display module respectively; the voice collection module includes a microphone for collecting voice, one end of the microphone is connected to a power amplifier circuit, the voice collection module is connected to the infrared remote control module, and a speaker is connected to the infrared remote control module; the fan control module includes an interface circuit for controlling the fan to work in different gears, and the interface circuit is connected to the data processing module through a Hall switch circuit;

[0030] The voice acquisition module is used to acquire voice commands, convert human voice into electrical signals, and then perform preprocessing through the data processing module. By analyzing the characteristics of the voice signal such as frequency, energy, and harmonics, effective commands are extracted, and corresponding control signals are generated according to the effective commands. The control signals are used to control the fan control module for gear adjustment or control the adjustment of the lights, realizing the adjustment of the fan gears and lights through voice commands, and improving the user experience effect.

[0031] Voice control realizes device operation through voice commands. Compared with ordinary control which mainly operates through physical buttons or touch screens, the voice control of this application uses voice recognition technology to convert human voice commands into machine-executable commands, while ordinary control directly operates the device through physical buttons or touch screens. Voice control adopts advanced natural language processing technology and can understand more complex and diverse commands, while ordinary control usually can only perform simple operations such as turning on / off and adjusting. This application can decode the voice by obtaining the encoded information of historical information and the guiding information of the large language model, thereby improving the voice recognition effect.

[0032] The voice recognition model can be trained by combining the phoneme recognition task based on voice and the text generation task, which enhances the model's ability to extract voice information. And by fusing the features of associated sub-segments and recognizing the fusion results, the accuracy of voice recognition is improved.

[0033] As Figure 9 shown, the interface circuit includes a diode D1 connected between the positive and negative poles of the fan. One side of the diode D1 is connected in parallel with a plurality of connectors M for the fan to connect (such as M1, M2, and M3 in the figure).

[0034] Through the setting of the interface circuit, it is convenient to control the circuits corresponding to different gears of the fan through multiple connectors M respectively, so as to control the adjustment between different gears.

[0035] As Figure 7 shown, the Hall switch circuit includes a MOS transistor Q1 and a triode Q2. The source electrode of the MOS transistor Q1 is respectively connected with an inductor L1 and a ground diode D2. One end of the inductor L1 is connected with a ground capacitor EC2.

One end of the resistor R13 is connected to the collector of the triode Q2. The base of the triode Q2 is respectively connected with a ground resistor R15 and a resistor R14 for connecting with the data processing module.

[0036] Through the cooperation of the Hall switch circuit with the infrared remote control module and the voice acquisition module, it is convenient to convert the change in magnetic induction intensity into an electrical signal, and then control the on and off states of MOS transistor Q1 and triode Q2, thereby realizing the control of the entire circuit. This control method has the advantages of non-contact, low power consumption, long service life, high response frequency, etc.

The 14th pin of processing chip U4 is connected to the 2nd pin of processing chip U2 through resistor R5. The 13th pin of processing chip U4 is connected to the 3rd pin of processing chip U2 through resistor R6. The 8th pin of processing chip U4 is connected to resistor R10.

[0038] Both processing chip U2 and processing chip U4 adopt the XCX24A626 type of processing chip. Utilizing its powerful computing ability, it can preprocess the voice commands converted into electrical signals, and then extract effective commands by analyzing the characteristics such as the frequency, energy, and harmonics of the voice signals, and generate corresponding control signals according to the effective commands. For example, if the command "increase the fan speed" is recognized, a signal for controlling the increase in the rotation speed of the fan motor is generated; if the command "dim the light" is recognized, a signal for controlling the reduction of the brightness of the LED dimming circuit is generated.

[0039] As Figure 3 shown, the infrared remote control module includes decoding chip U5 for receiving and processing remote control signals. The 1st pin of decoding chip U5 is connected to the 10th pin of processing chip U4 through resistor R3. The 2nd pin of decoding chip U5 is connected to the 9th pin of processing chip U4 through resistor R4. Connectors J1 for programming connection are connected to the 3rd and 4th pins of decoding chip U5. The 16th and 12th pins of decoding chip U5 are both connected to the power amplification circuit. The 8th pin of decoding chip U5 is connected to capacitor C5. One end of capacitor C5 is connected to connection terminal SP for connecting to the speaker. The 18th pin of decoding chip U5 is connected to ground capacitor C4.

[0040] Through the cooperation of decoding chip U5 and connection terminal SP, it is used to provide feedback or a prompt sound when receiving a voice command to tell the user that the command has been received and executed, facilitating the user to confirm the state of voice reception.

A connection terminal SPK for connecting to a microphone is connected between the pin 8 and the pin 5 of the power amplifier chip U3.

[0042] Through the cooperation of the connection terminal SPK and the power amplifier chip U3, the received audio signal can be denoised and amplified to a sufficient power level, and then transmitted to the infrared remote control module for processing and voice feedback on the received signal.

[0043] As Figure 6 As shown, the display module includes a liquid crystal display LCD. The pins 5 to 11 of the liquid crystal display LCD are respectively connected to the processing chip U2.

A pull-up resistor R12 is connected to the pins 11 to 15 of the processing chip U2. A connector J2 for program burning connection is connected to the pins 2 and 3 of the processing chip U2.

[0044] Through the setting of the liquid crystal display LCD, it is convenient to display the current status information of the radiator body in real time, such as the fan speed or the brightness of the light, etc., improving the convenience for personnel to master the working status of the radiator.

[0045] It should be noted that the radiator body is composed of an upper clamping plate, a lower clamping plate, an upper folding plate, a lower folding plate, a first connecting plate, a second connecting plate, and a heat dissipation box. Place the notebook on the cover at the upper opening of the heat dissipation box, and turn on the cooling fan on the heat dissipation box. The blades of the cooling fan rotate at high speed, and the heat generated by the operation of the notebook can be taken away in time through the heat dissipation holes, achieving the purpose of heat dissipation and temperature reduction. For example, a notebook radiator is disclosed in the patent document with the application number 201811255229.4, which will not be elaborated here.
