Leqing's unique "vibration sounding" technology

[Audio Network Information] The resonant audio industry is not a violent industry. In the case that domestic independent innovation technologies have not reached the developed level, the most critical core competitiveness of the industry lies in scale and operation management. For Leqing (Beijing) Application Technology Co., Ltd., the creation of its own technology and efficient management is the key. The biggest challenge at present is how to balance the customer experience and efficiency, effectively manage their own cost structure, and make the price system very competitive.

The following is an analysis of the independent innovation technology and capabilities of Leqing.

Core Technology <br> Leqing (Beijing) Application Technology Co., Ltd. has nearly 20 patents issued by the State Intellectual Property Office in relation to the vibration and audio field, including 6 utility model patents and more than 10 appearance patents. At the same time, two international PCT protections related to these patents are also in the bid. Based on these patented technologies, the MUSIC ENGINE music engine (hereinafter referred to as the ME engine) is used in Leqing's business, engineering, outdoor, professional audio, special customization and other products. The holding of patented technology and the hard work of many professionals and expert advisory groups ensure that Leqing continues to introduce high-tech electronic products of different grades.

In contrast, companies that manufacture similar products on the market mostly adopt a magnetostrictive rare earth material (GMM material), which is a patented technology disclosed in foreign countries in recent years. The domestic patented technology is the smelting technology of rare earth materials. Because the ratio of metal materials is slightly different, this technology is currently held by 2-3 companies in China, and these companies are all material smelters, not vibration sound. Product manufacturer. Companies based on rare earth materials as core technologies are using the principle of stretching of rare earth materials. In general, it is to purchase core materials from rare earth materials companies and process them into one part of their own products, while the patented technology is in the material smelting company. Therefore, most companies on the market that develop sound and vibration products based on rare earth materials do not have their own patented technology. Only a patented technical material was used.

Product Stability <br> Leqing's products are based on its own core patented technology. This technology uses traditional and mature materials to ensure more stable product performance through patented structure. Through continuous uninterrupted peak power test for more than 570 hours, there are no abnormalities in temperature, life, audio stability, etc., and consumers can use it with confidence.

The rare earth material is a crystal structure, and the crystal material is vibrated by the expansion and contraction deformation in the changing magnetic field, and finally the vibration is transmitted to drive the medium to sound. Since this crystal material will pulverize after a period of time in the natural state, that is to say, the final destination of a crystal material is a pile of powder; and we know that the continuous vibration energy is extremely large, and once the crystal material is slightly Damaged, the material will be shattered in a short period of time, coupled with the catalysis of the pulverization process, the external performance is that the sound of the product gradually or quickly appears noise, distortion, volume becomes smaller, and the final function disappears. This weathering cycle can be 3 months or less, or it can be 1-2 years or more.

Acoustic effect <br> Leqing's products are made of traditional mature materials, which ensure the stability and durability of the products. The distortion is small, the frequency response range is wide, the feedback is uniform from 70hz to 18kHz, the low frequency effect is obvious, and the hearing is comfortable.

Rare earth materials were originally used in ultrasonic exploration, sonar, industrial precision control and other professional fields. The material properties are characterized by precise expansion and contraction and frequency response in high frequency bands. The low frequency performance is relatively poor. We know that the human ear's hearing threshold is 20Hz. ~20kHz, for people's audible threshold, this is an obvious lack, because the frequency response range is too close to the high frequency, resulting in a sense of hearing is not full enough, long-term can lead to people's discomfort. In addition, the amount of expansion and contraction of the rare earth material is proportional to the length of the material, that is, it is impossible to achieve high power in a small space.

All of Leqing's products are characterized by versatility and simplicity. For example, Touching, although it includes Bluetooth, TF card, audio cable, and three playback modes, the operation is very simple, basically one-button operation. The product's Taking function is simple and easy to operate. It only requires one cable and no adapter. USB direct power supply, low power consumption, small size, portable, instant application.

Continuous research and development capabilities <br> LeQing, which has mastered the core technology of the resonance field, is still unremittingly exploring. The company's existing products have used the third generation of vibration module technology, while the fourth generation modules have production conditions, and the fifth generation modules are also In research and development. At the same time, to the expansion of research and development of other digital products, Leqing has made a large amount of technical reserves. On the other hand, Leqing Company pays great attention to industrial design, and has carried out extensive and extensive cooperation with top domestic designers and design institutes to design a variety of products that are popular among the public.

The core competitiveness of Leqing Company is positioned in the research and development and promotion of application technology. It has technical support from well-known scientists in many related industries; the professional technical support team of more than ten people; and the ability to update subsequent products and technologies. It is reported that the current flat-panel speakers, music home, conference audio system, etc. are in the process of research and development, Leqing will also be launched in the future.
