[0026] See Figure 1-10 As shown, the technical solution adopted in this specific embodiment is as follows: it includes a support plate assembly 1, a Bluetooth speaker 2, a support rod 3, and a rotating base 4. The rotating base 4 is disposed on the Bluetooth speaker 2. The two ends of the support rod 3 are respectively connected to the support plate assembly 1 and the rotating base 4. In this embodiment, in order to facilitate the adjustment of the placement angle and viewing angle of the device, a support rod structure and a rotating base structure are provided. The support rod connects the support plate assembly and the rotating base, so that the support plate assembly can rotate at the top of the support rod. The connection joint adopts the tight fit of the shaft and the shaft hole to achieve adjustment and positioning. Similarly, the connection between the support rod and the rotating base can also be freely adjusted and positioned. After adjusting the placement angle, rotating the rotating base can adjust the viewing angle, so that the viewing angle can be adjusted without affecting the sound output position of the Bluetooth speaker, making it more user-friendly.

[0027] More specifically, the Bluetooth speaker 2 is equipped with a control motherboard 6 and a colorful LED light assembly 7. The control motherboard 6 and the colorful LED light assembly 7 are electrically connected. The Bluetooth speaker is also equipped with a rechargeable battery that is electrically connected to the control motherboard. The control motherboard 6 is equipped with a main control coordination module 61 and an RGB LED driver module 62. The colorful LED light assembly includes a control light board and multiple RGB tri-color LEDs arranged around it. In this embodiment, an audio and ambient light follow control circuit is adopted, with a multi-modal interaction mode. The audio volume, light brightness, and color temperature are linked in three dimensions, resulting in a stronger sense of atmosphere.

[0028] Specifically, the main control coordination module 61 uses the AB5605C chip, which integrates Bluetooth protocol stack, audio codec, and PWM light control. It can wirelessly connect to devices via Bluetooth module, and decodes the transmitted audio data through audio codec and outputs it after DSP processing, resulting in better sound quality. Under the action of PWM dimming control circuit, it can combine light and audio signals, controlling the LED lights to link with the audio signals. Red light corresponds to low frequency signal, green light corresponds to mid frequency signal, and blue light corresponds to high frequency signal, enabling the LED lights to perform colorful rhythms. When silent, it has a breathing light effect, which greatly enhances the atmosphere and brings a better user experience.

[0029] More specifically, the support plate assembly 1 includes a support plate 11 and a support base 12. The support plate 11 has a support base mounting groove 112 in the lower middle part of its back side. The support base 12 is disposed in the support base mounting groove 112 and a magnet 14 is disposed in the support base 12. In this embodiment, a magnet is disposed in the support base so that the device can be attracted by the magnet after it is placed, which increases the stability of the device and makes it less likely to fall off accidentally during use.

[0030] More specifically, the lower part of the support plate 11 is provided with a support shaft 111, and a tray 13 is provided on the support shaft 111. The lower part of the tray 13 is provided with a rotating slot 131 that is movably connected to the support shaft 111. In this embodiment, two slots are opened on the support plate, and the support shaft is provided in the slots. The tray structure is snapped on the support shaft. The bottom of the tray is constrained by the bottom of the slot to limit its opening, which can support the device placed on it. In addition, the magnetic attraction of the magnet can be used to attract and fasten the device, improving the user experience.

[0031] More specifically, the rotating base 4 includes a rotating connecting platform 41 and a rotating fixing base 42. The upper part of the rotating connecting platform 41 is a clamping structure, and the bottom is a stepped base plate structure. The middle part of the rotating fixing base 42 is a hollow structure, and the inner diameter of the hollow part cooperates with the stepped base plate of the rotating connecting platform 41 to constrain the rotating connecting platform 41. In this embodiment, the rotating fixing base is installed on the Bluetooth speaker, and the rotating connecting platform is limited and fixed by the rotating fixing base, and can rotate within it, thereby realizing the adjustment of the viewing angle.

[0032] More specifically, the rotating connecting table 41 is provided with a limiting groove 411 on one side, and a limiting head 43 is provided in the limiting groove 411. The inner wall of the rotating fixed seat 42 is provided with a plurality of positioning grooves 421 arranged around it. The positioning grooves 421 match the limiting head 43, and the end of the limiting head 43 is provided with a spring. When the rotating connecting table rotates, the limiting head and the positioning groove cooperate. The positioning groove will continuously press the limiting head back, and under the action of the spring, the limiting head will be pushed into the adjacent positioning groove, thereby realizing the rotational positioning of the rotating connecting table and obtaining a better rotational positioning feel.

[0033] More specifically, the Bluetooth speaker 2 includes a light-transmitting shell 21, a base 22, a faceplate 23, a fixing cover 24, and a speaker 5. The light-transmitting shell 21 is disposed on the base 22, the speaker 5 is disposed on the base 22, the fixing cover 24 is disposed on the light-transmitting shell 21 and constrains and fixes the speaker 5, and the faceplate 23 is disposed on the light-transmitting shell 21 and constrains the fixing cover 24. In this embodiment, the Bluetooth speaker is provided with a light-transmitting shell that can cooperate with colorful LED lights for lighting display, and the speaker is electrically connected to the main control coordination module to play audio signals output by the playback device.

[0034] More specifically, the RGB LED driving module 62 includes a PWM driving circuit and a dynamic dimming module. The PWM signal controls the tri-color LED array and the driving circuit. The PWM driving circuit drives the red, green, and blue LEDs through transistors. In the control circuit of this embodiment, the driving of the tri-color LEDs is achieved through the PWM driving circuit. By driving the red / green / blue LEDs through transistors, the current matching of each channel is ensured (error < 5%), resulting in a faster response speed and less likelihood of false display during light display.

[0035] The dynamic dimming module includes audio linkage and flicker suppression. In this embodiment, the control of the light also relies on the dynamic dimming module, which is also a dynamic dimming algorithm. A stereo audio power amplifier circuit is also set on the control motherboard. The stereo audio amplifier circuit receives the output control information of the main control coordination module, decodes and amplifies the audio signal, and outputs the audio through the speaker. At the same time as the audio signal is transmitted to the stereo audio amplifier circuit, the audio signal is also transmitted to the PWM drive circuit. At this time, the audio linkage module synchronizes with the audio volume in real time through the PWM duty cycle. The louder the volume, the brighter the light. A corresponding APP can be installed on mobile phones and tablets to manually adjust the light and set more modes of ambient light to meet the needs of different users.

[0036] The PWM frequency in the flicker suppression module is fixed at 50kHz (REC). 256 brightness levels are achieved through hardware grading. In this embodiment, the hardware grading is configured via GPIO to achieve three frequencies: 25kHz / 50kHz / 100kHz. The duty cycle varies according to a logarithmic curve (0-100% brightness corresponds to 8-24 bit grayscale levels), avoiding abrupt visual changes. This results in better lighting effects and prevents visual discomfort caused by sudden changes in light, thus improving the user experience.

[0037] In another embodiment, a photoresistor can be set to collect ambient brightness, so that the light brightness can be automatically adjusted according to the ambient brightness.

[0038] The working principle of this utility model is as follows: In the support plate assembly 1, the support base 12 and the support rod 3 are movably connected through a shaft hole and a connecting shaft, and the connecting shaft and the shaft hole fit tightly. This allows the support base 12, along with the support plate 11, to be freely adjustable in angle and positioned. Similarly, the movable connection between the support rod 3 and the rotating connecting table 41 is also adjusted and positioned through the tight fit between the connecting shaft and the shaft hole. When the tray 13 is pulled open, the tray 13 near the bottom of the rotating slot 131 will abut against the edge of the empty slot below the support rotating shaft 111, thus limiting the position of the tray 13. The equipment can then be placed on the tray 13. At this time, the water level of the equipment can also be adjusted. Viewing from the side, rotating the rotating connecting platform 41 causes the positioning groove 421 to press the limiting head 43 back. Under the action of the spring, the limiting head 43 enters the adjacent positioning groove 421, thus achieving the rotational positioning of the rotating connecting platform 41. After the support adjustment is completed, the device can be wirelessly connected to the Bluetooth speaker 2 via Bluetooth to start use. The Bluetooth speaker 2 is equipped with relevant switches and function buttons. After turning on the colorful LED light component 7, the photoresistor collects the ambient brightness and automatically adjusts the brightness and color temperature. After the wireless connection is completed, the main control coordination module 61 coordinates the work of each sub-module through the microcontroller. RGB The LED driver module 62 controls the LEDs of the colorful LED light assembly 7 to achieve dynamic color mixing and brightness adjustment. During the adjustment process, the current mirror circuit drives the red / green / blue LEDs through transistors to ensure current matching of each channel (error < 5%). This ensures that the flashing of the lights and the follow-up effect of the audio are more precise and better when playing audio. In the audio linkage circuit, the PWM duty cycle is synchronized with the audio volume in real time. The louder the volume, the brighter the light. The PWM frequency is fixed at 50kHz. 256 levels of brightness are achieved through hardware grading (25kHz / 50kHz / 100kHz) to avoid visual abrupt changes and obtain a better atmosphere effect.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
