DSP audio processing chip applied in portable bluetooth speaker

Bluetooth speakers are one of the types of speakers on the market. When people choose a Bluetooth speaker, they will consider its working principle and know more about its types. Bluetooth speaker is to apply Bluetooth technology to traditional digital and multimedia speakers, so that users can listen to music freely in various ways without being entangled by annoying wires. Since the advent of Bluetooth speakers, with the development of smart terminals, they have received widespread attention from users such as mobile phones and tablets.

The first is signal conversion. When a user connects a mobile phone or other audio equipment via Bluetooth, the digital signal sent by the mobile phone or equipment will be converted into an analog signal by the Bluetooth audio receiver. In this process, the Bluetooth audio receiver will convert the digital signal into an electrical signal, and then convert it into an analog signal through an audio processor.
Bluetooth speakers use the "point-to-point" transmission method. The advantage is that they can guarantee good privacy and security, and the music synchronization is more stable; WiFi speakers can realize "-to-many" playback, and users can control different rooms through the APP. The WiFi speakers play different music, but the WiFi is easily disturbed when there are many users, and the music synchronization is unstable.
The Bluetooth speaker is just a sound playback device, and it cannot be used as an independent sound source. To a certain extent, it must be limited by the player and will occupy the audio channel of the mobile phone; the WiFi speaker can be used as an independent sound source to play music without the need Download the music first, then decode and play it directly on the speakers. You can listen to music on the WiFi speaker while watching videos or other tasks on your mobile phone, which can realize multi-tasking playback.
DSP is a kind of embedded general-purpose programmable microprocessor, which is mainly used to realize algorithm processing such as signal acquisition, recognition, transformation, enhancement, and control. It is the "brain" of various embedded systems and is widely used. At the same time, DSP chips also have the characteristics of low power consumption, low cost, and easy integration, so DSP chips have been widely used in audio, articles, communications, radar, medical and other fields.
Features of DSP chip:
1. High-speed computing capability: DSP chip has high-speed computing capability and can complete a large number of digital signal processing tasks in a short time.
2. Low power consumption: DSP chip adopts low power consumption design, which can reduce power consumption while ensuring high performance, and prolong battery life.
3. Easy to integrate: DSP chips can be integrated with other chips to form a complete system and improve the overall performance of the system.
4. Strong flexibility: DSP chips can be programmed according to different application requirements, with high flexibility.
