On April 16, in Guangzhou Haiyin Square, known as the birthplace of audio fever in South China, Genesis and Xuran Group released "digital audio solutions" and jointly opened the first evaluation experience meeting and evaluation room collection. The theme of the activity is "discovery, more than what you hear". The released audio solution applications include the Tiandi line box and the digital audio standing wave processor. Officially, this is a revolutionary technical solution in the audio field.
Digital audio development
All audio devices are inseparable from the control of sound waves. From mechanical sound generation to traditional electroacoustics, and then with the rapid development of science and technology, it has evolved into a digital audio scheme. With its characteristics of easy editing, large storage, easy carrying, etc., digital audio schemes cover a wide range of industries and have penetrated into all aspects of modern life.
Digital audio is a technology that uses digital means to record, store, edit, compress or play sound. It is a new sound processing method formed with the development of digital audio signal processing technology, computer technology and multimedia technology. The computer data is stored in the form of 0 and 1. The audio file is converted and then these level signals are converted into binary data for storage. When playing, these data are converted into analog level signals and sent to the loudspeaker for playing
In contrast, it has the advantages of convenient storage, low storage cost, no sound distortion in the process of storage and transmission, and very convenient editing and processing. With these excellent attributes, digital audio has rapidly spread to all walks of life. The imperceptible adult is a necessity in modern people's life.
Bottleneck of digital audio
Digital audio technology has the advantages of easy editing, large storage and convenient carrying. However, the electronic components that bring these advantages are also a double-edged sword, becoming the main "killer" of sound quality and the bottleneck of the development of digital audio field. Nowadays, high-power integrated equipment must have electromagnetic waves, which is a form of motion of electromagnetic fields. Any transmission or electromagnetic field accompanied by voltage and current will reduce the performance of a device, equipment or system.
For example, in mobile phones, the circuit board is composed of complex circuits and electronic components. The more complex the function, the more complex the structure of the circuit board. The higher the operating frequency between electronic components, the higher the frequency of electronic interference, that is, electromagnetic wave, radio frequency wave. The interference of radio frequency waves with different frequencies will affect the best working state of the equipment. Similarly, the digital audio working state of mobile phones will be seriously affected.
Audio technology solutions
Faced with the industries covered by digital audio technology, the people covered by these industries, the development of the current society, the improvement of people's living standards, and people's demand for audio quality. There is no doubt about the application market prospect of digital audio solutions. Take HIFI as a niche group, which has 3.5 million people in Guangdong Province, and its consumption capacity is beyond doubt. This is just one of the icebergs in the audio field. On the mobile side, according to statistics, as of the end of June 2015, the number of smart phone users was 593.57 million, and the market size was even more exaggerated.
The Tiandi Line Box and digital audio standing wave processor released this time are designed to solve the problem of digital audio. Audio standing wave processor is used to eliminate or improve electromagnetic interference and standing wave to improve sound quality. The Tiandi line box does not act as a sound source, but in the sound transmission carrier and space management, aiming to improve the sound field structure and eliminate the negative effects of negative microwave interference, electromagnetic interference, standing wave interference and radio frequency interference on sound waves in the air. The general principle is: the antenna senses and receives the negative wave elements, and the patent module inside the Tiandi cable box orderly releases the negative wave elements from the ground wire.
After half a year's appearance, the group's achievements have been widely recognized in the industry no matter where it is. In particular, at the Guangzhou Audio Music Exhibition in 2016, the "Digital Audio Solution", which appeared for the first time, not only solved the loss problem in the digital signal transmission process that has plagued the audio field for many years, but also achieved the HI-END level of sound quality. The playback solution is simple to operate, convenient to carry, and low in cost. If it is true as the manufacturer said, it will definitely be good news for major mobile users.
