Products Description
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).

# Analysis of Bluetooth speaker motherboard: How to achieve high-quality audio output

In the previous chapter, we discussed how to choose a Bluetooth speaker that suits your needs. Among them, audio output quality is one of the core factors to measure the performance of Bluetooth speakers. Behind this, the important role of the Bluetooth speaker motherboard is indispensable. This chapter will analyze the relevant knowledge of the Bluetooth speaker motherboard in detail for you, helping you to deeply understand the internal structure of the Bluetooth speaker and understand the secret of high-quality audio output.

 

## 1. Basic composition of Bluetooth speaker motherboard

The Bluetooth speaker motherboard is the core component of the speaker, which is mainly responsible for receiving, processing and outputting audio signals. Generally speaking, the main components of the Bluetooth speaker motherboard include:

### 1. Bluetooth module

The Bluetooth module is an important part of the motherboard, responsible for receiving and sending Bluetooth signals. The mainstream Bluetooth versions on the market are 4.0, 4.1, 4.2, 5.0, etc. Different versions of Bluetooth modules differ in transmission distance, stability and audio quality.

### 2. Audio processing chip

The audio processing chip is responsible for decoding, processing and modulating the received audio signals to meet the audio output requirements of the speaker. Common audio processing chips include brands such as CSR, BRCM, Qualcomm, etc. Different brands of chips differ in sound quality, decoding capabilities and power consumption.

### 3. Power amplifier

The power amplifier is responsible for amplifying the audio signal to sufficient power to drive the speaker to sound. Depending on the volume and sound quality requirements of the speaker, the design and configuration of the power amplifier will be different. Common power amplifiers include class-D, class-AB and other types. Different types of amplifiers differ in efficiency, sound quality and cost.

### 4. Power management chip

The power management chip is responsible for managing and regulating the power supply of the speaker to ensure that the speaker can work stably under different usage environments. The power management chip needs to have functions such as overheating protection, overvoltage protection and undervoltage protection.

### 5. Memory

The memory is mainly used to store the firmware program of the Bluetooth speaker to ensure the normal operation of the speaker. The size and type of memory capacity (such as flash memory, memory card, etc.) will affect the upgrade and compatibility of the speaker.

## 2. The impact of motherboard design on audio quality

The motherboard design of the Bluetooth speaker is directly related to the quality of the audio. Here are some motherboard design factors that affect audio quality:

### 1. Signal interference

Motherboard design needs to consider signal interference issues, especially during wireless transmission. Good shielding and grounding design can effectively reduce signal interference and improve audio quality.

### 2. Signal stability

Signal stability during Bluetooth transmission has a great impact on audio quality. Motherboard design needs to ensure stable signal transmission between the Bluetooth module and the audio processing chip to avoid signal loss and attenuation.

### 3. Sound quality adjustment

Sound quality adjustment is an important link in the motherboard design process. By adjusting the working parameters of the audio processing chip and the output characteristics of the power amplifier, the sound quality of the speaker can be made better.

### 4. Power supply

The stability and efficiency of the power supply also have a great impact on audio quality. The motherboard design needs to ensure the stability of the power supply of the speaker, while improving the power utilization efficiency and reducing power consumption.

## 3. Motherboard technology development trend

With the continuous development of science and technology, Bluetooth speaker motherboard technology is also constantly innovating. Here are some development trends:

### 1. Application of Bluetooth 5.0 and above

Bluetooth 5.0 and above have significantly improved transmission distance, stability and audio quality. In the future, motherboard design will pay more attention to the application of Bluetooth 5.0 and above.

### 2. High-performance audio processing chips

As consumers’ demand for sound quality increases, high-performance audio processing chips will gradually become mainstream. These chips can provide better decoding capabilities and sound quality processing effects.

### 3. Integrated design

Motherboard design will tend to be integrated, integrating more functions into a single chip to reduce costs, improve performance and simplify circuits.

### 4. Intelligence and personalization

Future Bluetooth speaker motherboards will pay more attention to intelligence and personalization, such as supporting voice assistants, customized sound effects, etc.

 

## IV. Conclusion

As the core component of the speaker, the Bluetooth speaker motherboard plays a key role in the quality of audio output. By understanding the motherboard composition, design influencing factors and development trends, we can better purchase and use Bluetooth speakers and enjoy a high-quality audio experience. I hope this chapter can provide you with useful knowledge and help you find your own wonderful sound in the world of Bluetooth speakers.
