Release Date: 2026 | Company News | Technology Innovation Announcement

Qunmao officially releases new generation audio solution, achieving comprehensive iteration of commercial display acoustic technology

As a leading professional manufacturer focusing on commercial interactive displays, self-service terminals, transparent display cabinets and smart visual equipment, Qunmao has always taken user experience upgrading and core technical iteration as the core driving force of product development. In response to the increasingly high-standard audio-visual experience requirements of global high-end commercial scenarios, brand flagship stores, enterprise conference rooms and exhibition display projects, the company has recently achieved a major breakthrough in built-in acoustic hardware technology. Based on the mature original 15W*2 dual-channel stereo speaker system, Qunmao has successfully added an independent 20W high-power subwoofer unit, creating an exclusive three-channel professional-grade audio solution for full-series commercial display equipment, completely rewriting the industry’s conventional audio configuration standards for mid-to-high-end commercial screens.

For a long time, most commercial display products on the market have been limited by structural design and cost control, generally adopting single dual-channel speaker configuration. Although they can meet basic voice broadcast and simple background music playback, they have obvious shortcomings such as insufficient low-frequency diving, weak sound field layering, flat sound quality and poor immersive sense. In high-end brand display, corporate summit conferences, digital exhibition hall display and large-scale commercial advertising scenarios, the lack of three-dimensional audio experience will directly reduce the overall grade of the project and weaken the audience’s visual and sensory perception. Relying on years of accumulated experience in commercial display hardware R&D and structural optimization, Qunmao’s technical team has overcome the difficulties of limited internal space of ultra-thin display equipment, acoustic resonance interference and power matching debugging, and finally completed the innovative upgrade from dual-channel stereo to triple-channel surround sound system, leading the new trend of high-fidelity audio-visual integration in the commercial display industry.

The new upgraded 15W*2 + 20W triple-channel architecture realizes full-band coverage of professional sound field

The new generation audio system launched by Qunmao continues the stable performance advantages of the classic 15W dual-channel stereo speakers, and carries out targeted structural optimization and acoustic tuning on the basis of retaining clear mid-high frequency resolution. The original dual 15W full-frequency speaker unit is responsible for restoring human voice, dialogue details, high-frequency music melody and daily voice broadcasting, ensuring clear, delicate and non-distorted sound output in various quiet and noisy environments. Whether it is corporate conference speech explanation, museum audio guide broadcasting, retail brand product introduction or public area voice notification, the dual 15W mainstream configuration can present accurate and penetrating mid-high frequency sound quality, meeting the daily business audio needs of most commercial projects.

Different from the single frequency band limitation of traditional dual-speaker displays, the newly added 20W independent high-power subwoofer fills the core gap of low-frequency sound field in commercial display equipment. The independent subwoofer unit adopts customized low-frequency vibration diaphragm and high-efficiency magnetic circuit design, which greatly enhances the bass diving depth and sound pressure level of the equipment. It can perfectly present heavy bass rhythm, dynamic music atmosphere, video background sound and panoramic sound effects, completely solving the industry pain points of thin sound, insufficient momentum and lack of three-dimensional sense of traditional commercial screens. The combination of 15W*2 dual full-frequency speakers + 20W independent subwoofer realizes the full coverage of high, medium and low full-band sound fields, forming a true three-dimensional surround sound effect, enabling ordinary commercial displays to achieve theater-level audio performance in real sense.

• 15W Dual Full-Frequency Speakers (Left & Right): Responsible for balanced output of mid and high frequencies, clear voice restoration, accurate sound positioning, suitable for conference explanation, voice broadcast and vocal music playback, ensuring zero distortion of human voice details.

• 20W Independent Subwoofer: Specialized in low-frequency enhancement, improving sound field thickness and dynamic tension, enhancing scene immersion, perfectly matching video advertising, dynamic promotional content and high-definition movie playback scenarios.

• Overall Triple-Channel Synergy: Independent frequency division tuning, no acoustic crosstalk, no resonance noise, realizing seamless docking of high, medium and low frequencies, making the whole sound field full, layered and three-dimensional.

Professional acoustic tuning technology eliminates structural interference and ensures stable high-fidelity output

The biggest technical difficulty of integrating high-power subwoofers into ultra-thin commercial displays lies in structural vibration interference and internal acoustic resonance. Most ordinary manufacturers cannot solve the problem of screen shaking and sound quality distortion caused by bass vibration, so they can only give up high-power low-frequency configuration and retain basic dual-channel speakers. Qunmao’s R&D team has carried out tens of thousands of acoustic simulation tests and structural debugging for this upgrade. By adopting independent acoustic cavity isolation technology, shock-absorbing silicone buffer structure and targeted frequency division algorithm optimization, the team completely isolates the vibration generated by the 20W subwoofer from the display screen body.

This innovative structural design effectively avoids screen jitter, picture floating and resonance noise during high-power bass playback, ensuring that while the audio quality is greatly upgraded, the ultra-high-definition display effect of the screen is not affected at all. At the same time, the team has carried out professional sound field calibration for different application scenarios, adjusting the sound pressure, frequency response and sound diffusion angle of the triple-channel system, so that the sound can be evenly diffused in large spaces, without local excessive volume or dead angle of sound field. Whether it is a small indoor conference room or a large exhibition hall of hundreds of square meters, it can present uniform, delicate and powerful professional sound effects.

In addition, the new audio system is equipped with an intelligent power adaptive adjustment module. When playing voice and light music, the system automatically reduces the subwoofer power to ensure clear and pure human voice; when playing dynamic videos and blockbuster materials, it automatically increases low-frequency output to enhance immersion. The intelligent switching of sound modes makes the audio-visual presentation more in line with scene logic, realizing truly intelligent and humanized acoustic experience.

Audio-visual integration upgrade comprehensively improves product competitiveness and project ROI value

The successful iteration of the 15W*2+20W triple-channel audio system marks that Qunmao’s commercial display products have officially entered the full-band high-fidelity audio-visual integration era, forming a huge differentiated advantage over homogeneous products in the market. At present, most peer products still stay in the single dual-channel audio configuration stage, with single sound field and ordinary experience, which is difficult to meet the high-standard experience needs of high-end brand customers and large engineering projects. Qunmao’s new audio upgrade completely breaks the industry configuration ceiling, making its self-service terminals, transparent display cabinets, vertical advertising screens and interactive teaching terminals have dual advantages of ultra-high-definition vision and theater-level sound quality.

For global brand dealers, engineering contractors and channel partners, this technical upgrade brings direct profit growth and project value improvement. First of all, the differentiated triple-channel audio configuration greatly improves the product premium ability, helping partners get rid of low-end homogeneous price competition and occupy the high-end commercial display market. Secondly, the immersive audio-visual effect can significantly enhance the attraction of retail display, brand promotion and exhibition display, effectively increase customer dwell time and brand impression, and create higher commercial conversion value for end customers.

Moreover, the integrated design of built-in high-power triple-channel speakers eliminates the need for external sound equipment in project deployment, saves the installation space and later wiring costs of engineering projects, simplifies the overall construction process, and reduces the hidden danger of equipment failure caused by external equipment matching. The integrated audio-visual all-in-one design makes the product more concise and beautiful in appearance, more unified in overall commercial space style, and more in line with the high aesthetic standards of European and American high-end commercial scenarios.
