2021 Jerry Technology Bluetooth Chip AC700N Launch Conference

2021-08-20

On the afternoon of May 26th, Jerry Technology held the 'Join Hands for Innovation, Win the Future' 2021 Jerry Technology 'Core' product online press conference, launching the new generation of Bluetooth earphone chip AC700N series, as well as the latest chip products in the three fields of Bluetooth Internet of Things/General MCU/General Audio.

In recent years, we have also deeply realized in the industry that there are more and more brand customers, and the requirements of brand customers are also increasing. This requires us, as the original chip manufacturer and our channel service provider, to provide higher quality and more professional technical services, in order to better serve our customers.

In the headphone industry, it relies on mobile phones, and there are many platform suppliers and platform partners who need us to integrate everyone's resources to inject some new highlights into the Bluetooth headphone industry. The earphone industry has been developing for so many years, but it is actually purely due to some inherent problems. Let me briefly share with you:

2、 Current Development Trends in the Bluetooth Industry

Mainly referring to the Bluetooth audio industry, Bluetooth headphones have been developed for many years. Everyone is looking at what the future Bluetooth industry can do and what other technical features can be developed. The first thing we will introduce is the LE AUDIO function, commonly known as Bluetooth 5.2. From 2019 to 2020, the Bluetooth Standardization Organization launched a new generation of Bluetooth standards, also known as Bluetooth 5.2, commonly known as LE AUDIO. The promotion of LE AUDIO technology enables reliable links between different TWS earphones, and standardizes the protocol of the links. Each customer does not need to privatize their own communication protocol. In addition, ENC and ANC are also a trend in voice, especially ENC. Nowadays, many customers have developed from single microphone headphones like dual microphone or even multi microphone trends. ENC and voice wake-up are a highlight of this industry and its future development. For example, voice wake-up can greatly facilitate operation, which is more in line with human operating methods and experiences.

1)Bluetooth earphones, as a transition from wired to wireless, first reduce the connection cable, which actually brings great difficulty to our wireless transmission. Everyone knows that wireless transmission will inevitably suffer from packet loss, interference, and the 2.4G frequency band. Nowadays, it is a public frequency band, whether it is Bluetooth, WiFi, ZigBee, or ordinary 2.4G. Everyone shares this frequency band, and wireless technology is to achieve reliable transmission in this complex electronic environment. How can wireless transmission be achieved wirelessly close to wired effects? This is a pain point that our Bluetooth industry is constantly pursuing.

2)While wireless transmission technology solves two problems: the first is the issue of power consumption; To solve the wireless performance of Bluetooth, it is often necessary to increase power consumption. However, increasing power consumption can be fatal for headphones because they are small and have a small built-in battery. We must go through many designs and breakthroughs to minimize the overall power consumption. When transmitting wirelessly, there is inevitably an increase in latency, as there will be retransmissions and signal loss. Therefore, it is necessary to have signal retransmissions to ensure signal continuity. During the retransmission process, there will inevitably be delays, which can lead to reduced gaming experience in specific areas, such as gaming. In addition, as an audio product, headphones are also important for sound quality because people want to achieve more beautiful melodies when listening to music. Therefore, we must put a lot of effort into sound quality. Of course, this sound quality not only refers to the sound quality of the music, but also needs to minimize noise as much as possible, reducing various aspects of noise during earphone playback or DNC.

3)Finally, as a communication product, Bluetooth's communication performance is also very important. For so many years, everyone has been tirelessly striving for the effectiveness of calls. We believe that this aspect has also been a focus of attention for everyone, especially brand customers. It is also a technical direction that Jerry Technology continues to challenge itself and does not develop. Therefore, today we bring you the new generation of Bluetooth earphone chip AC700N.
