Introduction

Jieli Bluet.sdleif nooth SoC is a remarkable series of system - on - a - chip developed by Zhuhai Jieli Technology Co., Ltd. It has found extensive applications in IoT intelligent terminal products, including AI smart speakers, Bluetooth speakers, Bluetooth headphones, and intelligent voice toys. This article will delve deeper into its features and application fields.

Features

High - performance processing capability
  • Multi - core processors: Many Jieli Bluetooth SoCs are equipped with dual - core or multi - core processors. For instance, the JL7016M is a 32 - bit high - performance dual - core SoC. With a processor frequency of up to 160MHz, it can handle multiple tasks simultaneously. This ensures the seamless operation of functions like audio processing and Bluetooth communication, enabling smooth user experiences even when multiple processes are running concurrently.
  • Built - in DSP: These SoCs integrate a dedicated digital signal processor (DSP). Take the 32 - bit DSP of the AC697N chip as an example. It supports hardware floating - point operations, which are crucial for efficiently processing audio signals. It can implement complex audio algorithms such as noise suppression, echo cancellation, and multi - band equalizers, significantly enhancing the audio quality.
Advanced Bluetooth technology
  • High - version Bluetooth protocols: Jieli Bluetooth SoCs support various high - version Bluetooth protocols, including Bluetooth 5.1, 5.3, and 6.0. The JL7016M integrates Bluetooth 5.3 BDR + EDR + BLE, while the AC7106A supports dual - mode Bluetooth 6.0 + LE Audio. These high - version protocols offer faster data transmission speeds, longer transmission distances, and lower power consumption, making data transfer more efficient and reliable.
  • Multiple Bluetooth functions: They come with functions such as intelligent dual - transmission master - slave seamless switching, automatic pairing, and over - the - air upgrade. The Jieli AC6936D, for example, supports Bluetooth 5.1 and features intelligent dual - transmission master - slave seamless switching and quick connection upon startup. These functions enhance the user experience by providing more convenient and stable Bluetooth connections.
Excellent audio processing capability
  • High - fidelity sound effects: Jieli Bluetooth SoCs support multiple audio coding and decoding formats, such as AAC, SBC, LDAC, and LC3. This enables high - fidelity audio playback. Some chips, like the JL7016M with its built - in 32 - bit DSP, can easily achieve high - fidelity sound effects, offering a wide dynamic range and clear, lossless audio experience for users.
  • Low - latency audio transmission: They have the characteristic of low - latency in audio processing and transmission. When the noise reduction function of the JL7016M is enabled, its latency can be as low as 20ms. This makes audio transmission more rapid and smooth, reducing audio stuttering and delay, which is especially important for real - time audio applications.
Low - power design
  • Multiple low - power modes: Jieli Bluetooth SoCs have multiple low - power operating modes and can use either LDO or DCDC power - supply modes. This flexibility allows them to meet the low - power requirements of different application scenarios. For example, the AC6936D chip has an ultra - low power consumption of 6mA, and the AC7006 supports the DCDC mode with a working current of 7 to 8mA.
  • Energy - saving technology: They adopt energy - saving chip design technology and Bluetooth low - energy (BLE) technology. When not in use or in standby mode, the chips can automatically enter the low - power mode, reducing power consumption and extending the device's battery life.

Application fields

Audio devices
  • Bluetooth headphones: Chips like JL708N and JL709N cover different - level products. They provide users with high - quality music playback and clear call experiences. These chips support functions such as active noise cancellation and transparency mode, enhancing the overall audio experience for headphone users.
  • Bluetooth speakers: Chips such as AC706N and AC695N are widely used in Bluetooth speakers. They support functions like FM radio, stereo, and one - to - multiple broadcasting, meeting users' audio - playing needs in different scenarios, whether it's for personal listening or group gatherings.
Smart wearable devices
  • Smart watches: The AC707N series chips are suitable for smart watches. They enable Bluetooth connection to mobile phones, allowing users to receive notifications and message reminders. Additionally, they support functions such as motion monitoring and heart - rate monitoring, all while ensuring the device's battery life.
IoT devices
  • Smart home: Chips such as AC635N can be applied to smart home devices like smart lights, smart sockets, and smart door locks. They enable Bluetooth connection and inter - connectivity between devices, allowing users to remotely control these devices through a mobile APP, enhancing home automation and convenience.
  • Smart toys: The AW30N series chips are Bluetooth + voice chips suitable for Bluetooth voice toys. They provide Bluetooth connection and voice - interaction functions for smart toys, enriching the gameplay and experience of toys, especially for children.
