Algorithm and software tuning: We collaborate with professional third-party companies. In addition, with the help of intelligent EQ and digital debugging tools, the sound can be finely and personalized adjusted, greatly improving debugging efficiency.

Hardware and structural innovation: Acoustic architecture is the physical foundation of sound quality. Can increase the volume of the vocal cavity by 29% in the same volume, enhancing low-frequency performance. We use wireless multi-channel technology to achieve a cinema level surround experience in home environments.

R&D facilities and cooperation: R&D relies on a professional environment. At the same time, industry university research cooperation with universities and international acoustic research institutions is the key to maintaining technological leadership.

Full process inspection: A rigorous system typically includes IQC, PQC, and OQC.

Environmental reliability testing: including high and low temperature, humid heat, salt spray corrosion testing, etc., to test the product's tolerance to different climates and corrosive environments.

Safety certification: The most common is China's CCC certification. It is worth noting that if the speaker is equipped with a power adapter or battery, these components themselves also need to have corresponding certifications.

Electromagnetic compatibility and radio certification: The electromagnetic interference generated by the product must not affect other devices, and it must also be able to resist interference. Entering the US market requires FCC certification, while the EU requires CE certification. In addition, the use of wireless technologies such as Bluetooth requires BQB certification from the Bluetooth Technology Alliance.

Environmental and other certifications: may include RoHS, energy efficiency labeling, etc. Enterprises usually entrust authoritative third-party testing laboratories with CNAS, CMA and other qualifications to complete relevant tests and issue reports
