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 Amplifier Board
# Bluetooth Speaker Amplifier Board: Injecting a powerful “heart” to the speaker
In the previous chapter, we learned the unique charm of the Apple Bluetooth speaker. However, a high -quality Bluetooth speaker is inseparable from an important component -Bluetooth power amplifier circuit board, which is the “bluetooth Speaker Amplifier Board” that we want to explore in this chapter.
## 1. The importance of Bluetooth amplifier circuit board
The Bluetooth amplifier circuit board plays a vital role in Bluetooth speakers, which is equivalent to the “heart” of the speaker. The main function of the amplifier board is to amplify the audio signal received by Bluetooth ** to drive the speaker unit. An excellent amplifier board can ensure the clear and full sound quality of the speaker, while improving the battery life and stability of the speaker.
## 2, the working principle of the Bluetooth amplifier circuit board
Bluetooth amplifier circuit boards are usually composed of audio signal processing chips, power amplifiers, and power management modules. When the Bluetooth speaker receives the audio signal, the audio signal processing chip will filter the signal, adjust the gain adjustment, etc., and then send the processing signal to the power amplifier. According to the size of the signal, the power amplifier drives the sound of the corresponding strength. At the same time, the power management module is responsible for providing a stable power supply for the entire amplifier board to ensure that the speakers work stable for a long time.
## 3, technical indicators of Bluetooth amplifier circuit board
When buying the Bluetooth amplifier circuit board, you need to pay attention to the following key technical indicators:
1. ** Output power **: The output power is an important indicator of the performance of the power amplifier board. The larger the output power, the greater the volume of the speaker, and the fuller the loudness.
2. ** signal-to-noise ratio **: Signal-To-Noise Ratio (SNR) indicates that the ability to suppress noise while amplifying audio signals. The higher the signal -to -noise ratio, the clearer the sound quality, and the better the hearing experience.
3. ** distortion **: distortion is the degree of distortion generated by the audio signal during the enlarged process. The lower the distortion, the better the sound quality is maintained, and the more natural the hearing.
4. ** Frequency response **: Frequency response refers to the audio frequency range that can be processed by the power plate. The wider the frequency response range, the better the sound quality of the speaker.
5. ** Battery Endurance **: Battery battery life is one of the important indicators of Bluetooth speakers. An excellent amplifier board can reduce power consumption and extend the battery life of the speaker.
## Four, the choice of Bluetooth amplifier circuit board
When choosing a Bluetooth amplifier circuit board, you need to choose according to the positioning, performance requirements and usage scenarios of the speaker. The following points are the factors that need to be considered when buying the Bluetooth amplifier circuit board:
1. ** Balance of performance and cost **: Under the premise of ensuring sound quality and performance, selectively selectively cost -effective power amplifier boards.
2. ** Brand and Word of Word: Choose a well -known brand or a good reputation amplifier board can ensure quality and stability.
3. ** Compatibility **: Ensure the compatibility of the amplifier board and Bluetooth speakers, which is convenient for subsequent replacement and upgrades.
4. ** Power supply method **: According to the power supply method of the speaker (such as battery power supply, USB power supply, etc.), select the corresponding power amplifier board.
###, recommendation of Bluetooth power amplifier circuit board
There are many brands and types of Bluetooth amplifier circuit board on the market. The following amplifier boards have a certain reputation and performance advantage. They can be used as a reference:
1. ** Maxim Integrated Max9744 **: This amplifier board has the characteristics of high output power, low distortion, etc., which is suitable for high -quality speaker products.
2. ** Texas Instruments TPA6120A2 **: This amplifier board has excellent audio processing performance and stable power management, which is widely used in various Bluetooth speakers.
3. ** Broadcom BCM2558 **: This power amplifier board integrates the Bluetooth module and power amplifier function. It has a small volume and low power consumption, suitable for portable speakers.
## 6. Installation and debugging of the Bluetooth amplifier circuit board
Installing the Bluetooth amplifier circuit board requires certain electronic knowledge and skills. During the installation process, pay attention to the following points:
1. ** circuit board layout **: Reasonable layout circuit board to ensure the shortest signal path and reduce signal loss.
2. ** Welding process **: Pay attention to temperature and time during welding to ensure that the solder joints are firm and full.
3. ** Debugging and test **: After the installation is completed, debug and test the power amplifier board to ensure that the sound quality and performance achieve the expected effect.
In short, as one of the core components of the Bluetooth speaker, the Bluetooth amplifier circuit board, its performance and stability are critical to the product quality of the entire speaker. In the process of buying and installation, you can learn more about its technical principles and performance indicators in detail. Choose the appropriate amplifier board to inject strong motivation into your speakers and allow you to enjoy a high -quality music experience.
