[0023] 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.
[0024] Please see Figure 1-6 This utility model provides a technical solution: a Bluetooth speaker fan, including a housing 1, a fan 5 installed inside the housing 1, a fan light ring 4 coaxially set with the fan 5 and emitting colorful light at the front end of the housing 1, and an electrically connected circuit board 14 and a speaker 13 installed inside the housing 1. The circuit board 14 is electrically connected to an LED display screen 7 that displays the parameters of the speaker 13, a button 8 that controls the speaker volume and music control, and a function port 12 that enables device operation.
[0025] The circuit board 14 also integrates a Bluetooth module, which uses a Bluetooth 5.0+EDR chip, supports A2DP / AVRCP protocols, and covers a transmission distance of 20 meters.
[0026] The fan light ring 4 has multiple RGB SMD LEDs embedded inside (supporting 16 million colors). The cover of the fan light ring 4 uses a matte, semi-transparent acrylic light guide plate to achieve uniform light diffusion. The light-emitting principle of the fan light ring 4 is based on existing technology and is briefly described as follows: the mixing ratio of the three primary colors is adjusted by outputting a PWM signal from the motherboard MCU. - Effects Synchronization: The FFT algorithm is activated when audio is input, causing the lights to change with the rhythm of the music.
[0027] The 12 functional ports include a DC-5V power interface, a USB interface, a TF interface, and an AUX interface;
[0028] The DC-5V power interface indicates that the fan 5 power supply needs to be matched with a 5V DC voltage, and the USB interface is mainly used for data transmission and power supply.
[0029] The TF interface is a memory card reader interface used to read data from a TF memory card and play music from the memory card.
[0030] The AUX interface is an audio input / output interface used to connect audio devices (mobile phones, MP3 players, computers, etc.), speakers, or headphones to transmit analog audio signals.
[0031] Furthermore, both the USB and TF interfaces support the expansion of a radio module, enabling radio functionality.
[0032] The top of the outer casing 1 is rounded, and the sides of the outer casing 1 are provided with decorative pieces 2 to enhance the aesthetics of the fan. The bottom of the outer casing 1 is provided with two silicone feet 103 to enhance the anti-slip properties and placement stability of the fan. The outer casing 1 includes a front casing 101 and a rear casing 102 connected by bolts.
[0033] Both the LED display screen 7 and the buttons 8 are mounted on the front cover 101, while the function port 12 is located on the rear cover 102. The buttons 8 are located below the LED display screen 7 and include, but are not limited to: volume control buttons (volume + / -), Bluetooth mode pairing buttons, previous / next track buttons, pause buttons, and light on / off buttons.
[0034] The front housing 101 has an air outlet, and a front mesh frame 3 is installed inside the air outlet. The rear housing 102 has an air inlet, and a rear mesh frame 10 is installed inside the air inlet. Both the front mesh frame 3 and the rear mesh frame 10 are coaxially arranged with the fan 5. Both the front mesh frame 3 and the rear mesh frame 10 include two concentric rings and multiple vertically arranged connecting rods connecting the two rings.
[0035] The fan light ring 4 is located on the outer perimeter of the front grille 3.
[0036] A rotary switch 6 is also installed on the front cover 101. Both the rotary switch 6 and the motor on the fan 5 are electrically connected to the circuit board 14. After rotating the rotary switch 6, the main control chip on the circuit board receives the adjustment signal and controls the motor on the fan 5 to run or adjust its speed. The control principle is existing technology and will not be described in detail here.
[0037] The front shell 101 has densely distributed horn mesh holes 9, and the rear shell 102 has horn vent holes 11. The horn mesh holes 9 are aligned with the sound-producing end of the horn 13, and the horn vent holes 11 are aligned with the mounting end of the horn 13. The horn vent holes 11 are used to dissipate the heat generated by the horn 13 during operation.
[0038] One side of the fan light ring 4 is connected to a flexible buckle 41. The front shell 101 has an annular mounting groove, and the inside of the mounting groove has a slot. The fan light ring 4 is installed inside the mounting groove, and the buckle 41 is engaged inside the slot.
[0039] When in use, after the device is powered on, turn the knob switch 6 to control the operation of the fan 5. By controlling the degree / angle of rotation of the knob switch 6, the speed of the fan 5 can be adjusted. While blowing air, you can press the Bluetooth mode pairing button on the button 8 to pair with Bluetooth (with mobile phones, computers, etc.) to achieve Bluetooth connection and play Bluetooth music. To increase the fun of blowing air, while listening to music, you can also turn on the fan light ring 4 by using the light switch to make the light change with the rhythm of the music.
[0040] Furthermore, a TF memory card can be connected to the TF interface in the function slot 12 to play music from the memory card, or an audio device (mobile phone, MP3 player, computer, etc.), speaker, or headphone can be connected via the AUX interface to transmit analog audio signals.
[0041] 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.
