Mood Light Bluetooth Speakers for Home
The Bluetooth speaker comes with 64 million colors of lights, which will change and flicker with the speed of the music. When the volume of the Bluetooth device is at 80-90% of the total volume, the light will flicker at a high frequency with the speed of the music. When the volume of the Bluetooth device is at 70-80% of the total volume, the light will flicker at a low frequency with the speed of the music. When the volume of the Bluetooth device is below 70% of the total volume, all 64 million colors of lights will be automatically turned off, and the Bluetooth speaker system will automatically enter the hypnosis mode. At this time, the sound it plays is like a lullaby, giving people a comfortable rest environment. In addition, press and hold the power button for 3 seconds, and the Bluetooth speaker will enter the night light mode (i.e. warm white light lighting mode).

Bluetooth Speaker Kit Board: Construction, Functions and Selection Guide
Bluetooth speakers have become an indispensable part of modern life. Their portability and wireless connection capabilities have brought great convenience to users. One of the core components of Bluetooth speakers is the so-called “kit board” – that is, the circuit board. This article will take a deep look at the construction, functions and how to choose the right circuit board for Bluetooth speaker circuit boards.

Construction of Bluetooth Speaker Circuit Board
The circuit board of a Bluetooth speaker, commonly known as a PCB (Printed Circuit Board), is an important part of the device. It contains all the electronic components, such as Bluetooth modules, amplifiers, sensors, interfaces, etc., which are connected together by wires and solder joints to form a complete circuit.
1. **Bluetooth module**: This is the core component on the circuit board, responsible for receiving and sending wireless signals. Modern Bluetooth speakers usually use modules that support Bluetooth 5.0 or higher to provide better connection speed and stability.
2. **Amplifier**: The amplifier on the speaker circuit board is responsible for converting digital signals into sufficient analog signals to drive the speaker unit to make sound. The quality of the amplifier directly affects the sound quality and volume of the speaker.
3. **Power management**: The circuit board also contains a power management module, which is responsible for providing stable power to the entire circuit, and manages and distributes the power to ensure that each component can work at the correct voltage and current.
4. **Microcontroller**: Many high-quality Bluetooth speaker circuit boards will integrate a microcontroller to manage audio playback, user input, various settings, and communication with external devices.
5. **Interface**: There will be various interfaces on the circuit board, such as USB, AUX input, charging interface, etc., which are convenient for users to perform various operations and connections.
Functions of Bluetooth speaker circuit boards
The main function of Bluetooth speaker circuit boards is to process and transmit audio signals to ensure that users can hear clear and high-quality music. In addition, modern Bluetooth speaker circuit boards also have the following functions:
1. **Wireless connection**: The Bluetooth module supports wireless connection, allowing users to pair their mobile phones, tablets or other devices with it to play music and voice calls.
2. **Multi-device connection**: Many Bluetooth speaker circuit boards support fast switching between multiple devices, and users can seamlessly switch music playback between multiple devices.
3. **Sound quality processing**: High-quality circuit boards can process high-fidelity audio signals and provide clear and balanced sound quality.
4. **Intelligent control**: The integrated microcontroller can realize intelligent functions such as voice assistant control, playlist management, ambient sound effects, etc.
5. **Battery management**: The power management module is not only responsible for power supply, but also for battery charge and discharge management to ensure the battery life and safety.
How to choose the right Bluetooth speaker circuit board
When choosing a Bluetooth speaker circuit board, you need to consider the following factors:
1. **Compatibility**: Make sure the circuit board supports the latest Bluetooth standards and is compatible with your device.
2. **Sound quality**: High-quality circuit boards can provide better sound quality. Consider audio processing capabilities when choosing.
3. **Battery life**: The power management capabilities of the circuit board are directly related to the battery life. Pay attention to the performance of the battery management module when choosing.
4. **Additional functions**: Consider whether additional functions such as multi-device connection and intelligent control are needed.
5. **Manufacturer and brand**: Circuit boards from well-known brands are usually more reliable and have better after-sales service.
6. **Cost**: Consider the budget, but also be careful not to sacrifice important performance and quality.

Conclusion
The circuit board of a Bluetooth speaker is its core component, responsible for processing and transmitting audio signals, providing stable wireless connection and high-quality sound quality. When choosing a suitable circuit board, you should consider factors such as compatibility, sound quality, battery life, and additional functions. Doing enough market research before purchasing and choosing products with well-known brands and good reputations can ensure a satisfactory user experience.
