After over a decade of growth, it has specialized in testing automotive speakers, AVAS, buzzers, electric horns, switches, and spring products. In 2020, it was recognized as the Engineering Laboratory for Automotive Speakers and Spring Elastic Components by the Jining Development and Reform Commission.
The Experimental Center features multiple functional zones, including material, mechanical, and acoustic labs. It conducts type tests and R&D for electric horns, speakers, springs, etc., and performs various tests like material property detection, environmental simulations, and durability checks. Testing standards comply with national, industry, German, Japanese, and major automaker requirements.
Self-developed speakers excel in adaptability and innovation. Tailored to the unique needs of AVAS and buzzers in new energy vehicles, our R&D team refined acoustic algorithms and hardware integration through thousands of tests, ensuring seamless system integration. This end-to-end control cuts costs and guarantees high reliability, highlighting our deep acoustic know-how.
Our R&D efforts also drive product innovation, incorporating cutting-edge tech to achieve industry-leading sound quality and environmental resilience. This has earned us partnerships with top automakers like BYD, Volkswagen, and Geely. With a strong domestic presence and exports to Iran, Kazakhstan, and Russia, we've proven our ability to drive innovation and scale up globally in automotive acoustics.
In the production of Acoustic Vehicle Alerting Systems (AVAS), the core component—the loudspeaker—is entirely independently developed and manufactured by our company. Simultaneously, the printed circuit board assemblies (PCBA) used in the system are also fully based on independent design and production. Utilizing in-house core components provides multiple advantages for AVAS products: on the one hand, since both the loudspeaker and the circuit boards originate from the same research and development ecosystem, they can achieve deep integration during the design phase, ensuring system compatibility and optimal performance, fundamentally avoiding potential compatibility risks that may arise from multi-supplier components; on the other hand, this enables us to exercise more effective control over the supply chain, respond quickly to production demands, and implement strict quality control standards at every stage of the manufacturing process.
We possess a professional surface-mount production workshop, equipped with automated production lines and a full complement of operational personnel. During the production process, the Manufacturing Execution System traces the entire production workflow, enabling precise tracking of each component's production milestones and effectively preventing quality issues caused by human errors through error-proofing mechanisms.
The solder paste inspection equipment we employ features three-dimensional detection capabilities, allowing for 100% inspection of all solder joints and comprehensive monitoring of the morphological parameters of the printed solder paste, ensuring the quality of subsequent placement processes. The three-dimensional optical inspection equipment, on the other hand, conducts comprehensive inspections of soldering quality after the placement process is completed, including top-view inspections of the soldering conditions of component pins, ensuring reliable soldering quality of the finished products.
All production equipment meets automotive-grade manufacturing standards. The workshop environment is maintained at a constant temperature and humidity, with cleanliness and electrostatic protection levels fully compliant with automotive production requirements. The warehousing system is equipped with intelligent environmental control functions and, through intelligent integration with the manufacturing system, enables full-process control such as precise material management, error-proofing in operations, and first-in-first-out principles. The automated coating production line features multi-angle processing capabilities, allowing for precision machining of circuit boards through multiple processes such as protective coating application and adhesive dispensing.
Qufu TEMB Automotive Electric Co., Ltd is capable of independently manufacturing horn echo boards and owns an automatic diaphragm forming machine. The introduction of this machine has further improved production efficiency and product consistency. It can operate 24 hours a day with only 1 to 2 personnel in charge. Compared with traditional production methods, it significantly increases output within the same period while ensuring more stable quality, providing strong support for the company's competitiveness in the automotive electroacoustics market.
Leveraging its technical accumulation in the automotive electroacoustics field, the company independently researches, develops and produces horn echo boards. By controlling product quality from the source, it ensures the matching accuracy between echo boards and other electroacoustic components, thereby enhancing the overall performance of the horns
