Guangzhou Weiniu Intelligent Technology Co., Ltd. is a large professional audio manufacturer and service provider integrating research and development, design, production, sales and service. After years of development, it has formed a professional speaker, electronic equipment, multiple marketing companies, multiple provincial agents and after-sales service providers, and become an integrated audio enterprise of production, sales and service. The company established its own brand "Lifeng Power", covering professional audio products and application detection systems. From the research and development of units to the innovation of various circuit structures and component manufacturing technologies, the company has compiled advanced design software, optimized the electroacoustic structure of the sound system, and produced excellent electroacoustic and electronic products. Independent research and development of intelligent professional speaker detection system can distinguish whether the speaker is connected correctly through the box indicator light. Break through the revolution of traditional speaker relying on manual detection, directly and effectively detect whether the phase connection line of the speaker is correct, and ensure the true restoration of the speaker to the sound. In the sound production system of the audio system, we focus on the research and development of the expressive force of the human voice, so as to promote the excellent performance of each product. It breaks the strategy of using external frequency division for traditional linear array speakers, reduces the difficulty of tuning the sound quality of linear array tuners, and solves the confusion of users in tuning the sound quality. It is very difficult to calibrate the built-in frequency division of the linear array speaker. The tuner cannot fully know the sound quality of the speaker unit in the speaker. In the later debugging, the original characteristics of the speaker cannot be brought into play, and the threshold for the calibration of the linear array speaker is raised in disguised form. Our company brainstorms, breaks the traditional linear array manufacturing mode, and uses the built-in tuned frequency divider to present perfect sound quality, reduce the burden of users, and solve the integrated audio combination. The company continues to follow the customer-oriented and perfect service concept, and strives to meet the needs of customers.
