HD Audio Encoder Modulator Assembly
As with every high-performance design, a system-wide approach to the entire audio signal chain ensures a powerful and high-performance solution. Because each link in the audio signal chain is important, make sure it has no weakest link, and each link must be able to meet all design target specifications, such as performance, cost, time-to-market, and ease of use.
The power management module provides the correct power level for the wi-fi speaker circuit. Suppose the application is powered by a system (not a battery) and depends on the output power. It also needs to provide clean and stable power rails to prevent any power noise from entering the audio system and reducing audio quality.

The connection module uses wi-fi or Bluetooth to provide wireless communication to the system through a computer, smartphone, tablet or wirelessly enabled product. Standard bluetooth modules today provide an all-in-one solution for portable audio systems because they support both wireless and wired audio. But since lossless high-resolution audio streams require higher bandwidth, their limited bandwidth is a potential bottleneck. The new bluetooth audio encoding technology promises to increase bandwidth to support hd audio.
Wi-fi, on the other hand, includes greater network capacity, powerful signaling, and a wider range of radio frequencies. Its increased bandwidth capacity and system throughput make it more suitable for hd audio applications. The processor performs various audio processing functions, such as decoding and signal balancing, as well as handling the wi-fi and/or bluetooth communication software stack. In the past, CD quality sampling frequency may have been sufficient. But today's high fidelity audio systems have other requirements for processors in the signal chain, because high fidelity audio quality requires sampling rates ranging from 48kHz to 192kHz in a 24-bit music signal stream.

The audio module contains all the electronics needed to drive the speakers in the system. Because the signals from the connecting module and processor have low voltage and current capabilities, the audio amplifier provides the signal with the higher voltage and current capabilities necessary to drive the drivers in the speaker system. The module can include an audio digital to analog audio converter (DAC) for converting digital audio signals from the processor to analog audio signals, and other audio processing in the digital domain to further enrich the customer experience in high-end systems. Another key component of the audio module is the audio amplifier.

Due to the limitation of the transmission medium and its format, the signals of both sides of the communication cannot be directly transmitted, but must be processed in a certain way to make it suitable for the characteristics of the transmission media before they can be correctly transmitted to the destination.
Modulation is the use of analog signals to carry digital or analog data; Coding is the use of digital signals to carry digital or analog data. At present, there are mainly two kinds of transmission channels: analog channel and digital channel, among which analog channel is generally used for transmitting analog signal, while digital channel is generally used for transmitting digital signal.
At this point, we need to first convert the transmitted data into the data type that the channel can transmit, namely the conversion of analog signal and digital signal, which is the main content of coding and modulation.
Of course, how to send analog data and digital data through channels is also an important part of coding and modulation. We can understand the modulation and coding of data from four aspects: analog signal transmitted by analog channel, analog signal transmitted by digital channel, digital signal transmitted by analog channel and digital signal transmitted by digital channel.
