Wellcrystal K20S before the birth!
Since its launch, Welljing K20S has attracted the attention and love of users. What ingenious, polished design thinking does it contain? Not long ago, we had an in-depth exchange with its project leader. Under his responsibility, how did the K20S go from dozens of sketches to what you see now? Let's hear its story together.
Birth of the K20S
What is the original intention of the high-end appearance and easy to carry design?
Wellcrystal Audio has always paid great attention to user experience, and everything is based on user experience.
When we did market research, we found that music festivals, music live and outdoor singing are becoming a way of life that people like to enjoy, and people prefer a close-up music atmosphere. In the era of national Internet celebrities, music lovers of all ages go outdoors and sing ideals with enthusiasm. Not only that, everyone also shared their singing voices to the network through live broadcasts for netizens across the country to see.
On the market, there are not many choices for high-value live broadcast singing Bluetooth speakers that can meet the portability, good sound quality and large power. In this context, we decided to make a live broadcast that is convenient for everyone to play and sing outdoors, and at the same time the workmanship should be exquisite, unique in sound quality, and the value-for-money outdoor roadshow can be used to play and sing live sound, so that singers can sing outdoors, and the audience can listen comfortably and enjoyably, create a unique and unforgettable music experience, and improve the overall quality of everyone's outdoor interpretation.
What are the unique product details of the WellCrystal K20S?
Bring the original sound back to life
Since it is an outdoor interpretation audio, the high-quality sound quality of K20S is a basic and important product positioning, and it is also the ultimate pursuit of our tuners.
For us, the positioning of the main sound quality does not mean that the material can be selected without restraint, which becomes the core issue of product trade-offs. After repeated arguments by the tuner, we finally opened the gap with other speakers through these two points:
First, the sound system uses two DSPs (Digital Signal Processors) to process the audio signal and four processing cores. This means that the K20S can handle multiple audio tasks at the same time, such as stereo, surround, equalizer, etc., providing higher quality sound effects.
The second is to adjust the equalizer on 15 different frequency bands of the audio signal to change the sound intensity in different frequency ranges to optimize sound quality. It is understood that similar products on the market have adjusted EQ in different frequency bands, but only a few have 15 adjustments, which means that the sound processing of K20S is clearer and more thorough, and the hearing sense has been greatly improved.
Other debugging, coupled with the ultimate processing of these two points, K20S not only allows the original sound to be reproduced, but also improves the audio space, whether it is playing and singing or listening, so that the sound infects people with a better attitude.
5-unit linear array acoustic structure
5 units line array arrangement
It's all about hearing the original intention. How can we differentiate ourselves from the same volume of singing sound on the market? To make it have a wide sound field and better sound quality, this has hard requirements for the acoustic structure. In order to ensure these two points, electroacoustic engineers have repeatedly tested and compared the t/s parameters of the speaker in the Weierjing Acoustic Laboratory, and carried out special technical treatment on the speaker, and tested the different acoustic combination structures, and determined the acoustic structure of the line array, so that the overall power of K20S has been greatly improved and the penetration is stronger in a limited box. With a rigorous attitude and all based on the concept of user experience, the engineers did not miss a single sound detail, and after repeated debugging of multiple versions, the sound of the K20S was finally clearly heard at the ideal distance, and the sound was clearly layered. The moment this effect was achieved, the engineers gently breathed a sigh of relief and signaled to each other, which is what we wanted.
Appearance and sound quality go hand in hand
In this era of appearance first, we consider the requirements of music lovers and street singers for product appearance, only by creating a delicate and unique appearance can we stand out among many visual elements and meet the aesthetics of more music lovers.
The essence of sound is to convert the electronic signal into sound waves and amplify, and then debug it through unique acoustic technology so that it can be heard by humans as the original sound effect. "Speaker" as the basis of the sound of such products, both ears as the first organ to receive sound, we have a bold idea to combine the acoustic configuration and appearance - two circular passive radiators are designed on both sides of the audio, which looks like a creative design of headphones to the audio, increasing the volume of the cabinet, making the bass surging down, and when playing music, the two passive radiators will also "dance" with the rhythm, which also makes the K20S have vitality and a more technological sense.
Bilateral low-frequency diaphragm
In order to be pure and full of sound quality, K20S uses a wooden cabinet, although the two-sided low-frequency diaphragm is creative, and to install a diaphragm on the wooden cabinet, it is necessary to solve the big problem of sealing. The sound of the diaphragm needs to be squeezed by the air in the box to make sound, if the box leaks, the diaphragm can not achieve the actual effect, resulting in the bass is not full, and even the sound will break. This requires high requirements for the material of the diaphragm, the design of the box and the workmanship. In order to preserve this creative design, the structural engineers finally solved this problem after repeated testing and demonstration. Every bit of improvement in appearance is related to performance. After the realization of the double ear inspiration diaphragm, not only the appearance is more distinctive, but in terms of sound quality, with the blessing of the bilateral diaphragm, the vocal thickness is better.
The patented LOGO lights up the music dream
In addition to the diaphragm blessing, the K20S is excellent in exterior detail design, high-grade skin and exquisite stitching craftsmanship, making it look more like a work of art. Another special design highlight full of creativity and connotation is the finishing touch of the Welljing K20S - lighting up the LOGO.
The team believes that K song sound is a product full of vitality and dreams, which should not only provide users with high-quality music experience, but also convey the attitude of music lovers to life and light up music dreams. After careful consideration, the designer added a special element - a luminous logo with brand identity - on the C position on the front of the sound - and applied for patent protection for this design.
K20S patent certificate
The finishing touch of this design is that when the user turns on the speaker, the logo lights up with the speaker and goes out when the device is turned off. This can not only enhance the fashion sense and visual appeal of the product, but also the LED light board LOGO of the C position also makes the sound more dynamic.
In addition to the design, this luminous LOGO also gives the product a deeper connotation. It lights up not only the audio, but also the user's musical dreams and free lifestyle. No matter where the user is, as long as they turn on the stereo, they can not only listen to soulful singing and enjoy beautiful music, but also feel their pursuit of music and enthusiasm for life.
The lighting LOGO also shows the pursuit of individuality and innovation of Wellcrystal Audio, allowing users to feel the infinite possibilities of music and life. This design not only improves the practicality and aesthetics of the product, but also gives music and life more connotation and soul.
4 wired inputs
The concept of user first is also reflected in rich functions, which K20S has indeed done. At the very beginning of the product project meeting, we considered the interpretation form to meet the performance of the band or several friends, so there were strong requirements for the number and effect of K20S microphone input and instrument input.

In the final product, in addition to the standard two wireless true diversity microphones, the K20S also supports two wired microphone inputs and two instrument inputs, which is a high-end configuration in such a large volume of audio. Moreover, the instrument and wired microphone inputs can be adjusted independently to adjust the sound quality according to the actual situation, whether you want a clear vocal interpretation or a passionate musical performance, the K20S allows users to get the best sound quality.
If you want to start a live stream or post your own singing video, then the K20S's OTG recording feature will definitely be the icing on the cake.
OTG digital live streaming
According to a report by the China Performance Industry Association, the online performance (live broadcast) industry anchor accounts have accumulated nearly 140 million, in such a huge live broadcast market, how to make the live broadcast sound quality of the anchors better presented in the live broadcast room, so that fans can hear the pure singing effect, engineers want K20S to provide high-quality live broadcast radio protection for anchors.
K20S singing live
After comparing and testing the solutions of many solution providers, we finally added the OTG digital live broadcast function on the basis of the analog live broadcast, and uploaded the high-definition audio of the live broadcast room to the live broadcast room through the digital live broadcast function, so that fans in the live broadcast room can listen to high-fidelity sound quality and give fans a live broadcast experience of the concert. Not only that, you can also use the OTG live broadcast interface to connect the mobile phone to shoot talent show video, after the connection, the mobile phone directly shoots the video, the audio of the video is also called OTG digital internal recording, the video sound quality has no ambient sound, the sound quality is pure and beautiful. With the blessing of OTG live broadcast function, K20S can not only provide high-quality live broadcast radio effects, but also easily shoot short videos with studio sound quality, which is convenient for users to record and share their performance videos to the short video platform, so that hundreds of millions of netizens can appreciate the musical talents of anchors.
Color aesthetics collide with acoustics
Let acoustics collide with diverse flowers in the color world, and the appearance of K20S must match acoustics. In terms of color matching, we only had one black at the beginning, and the marketing colleagues took into account the diversity and richness of street interpretation culture, and the characteristics of musical styles, and had the idea of combining music style and color, and finally presented three colors of jazz black, blues blue and gothic red, each color representing a different musical style.
K20S in three colors
The deep jazz black accentuates elegance and mystery, reminiscent of the soft sound of the piano you hear when strolling the city streets at night.
Gothic Red exudes freedom and passion, carrying deep emotions and stories.
Bruce Blue is full of rich artistic atmosphere, making people feel like they have traveled back in time to a medieval castle.
The sound itself is the sound of music, under the rendering of multiple colors on the outside, K20S will 100% represent the pursuit and love of music style of music lovers, whether it is looking for a jazz comfort in an elegant coffee shop, or feeling the free dance of blues in an open-air concert, K20S will fully contribute "sound" to music.
Finally, after debugging and testing by many engineers, K20S has become the choice of outdoor singing live singers and music lovers with its powerful functions, exquisite design, excellent sound quality and excellent use experience. We also want the K20S to be a part of street culture, a testament to everyone's love of music and the results of our continuous efforts.
In the future, we will continue to devote ourselves to product research and development and innovation, and bring more excellent products to the majority of users. We believe that music can enrich people's lives, and Wellcrystal can make the sound quality better, so that music lovers can enjoy better music charm.
