1. The project mainly focuses on the development and application of bone conduction headphones in the tourism market, targeting the tourist population, whether they are young, elderly, disabled or able-bodied. Design and develop bone conduction headphones using ergonomics and incorporating the characteristics of bone conduction, including Bluetooth wireless and wired wearing. Liberate both ears, protect hearing, and promote healthy tourism. 2. Project technology source: The company is a high-tech enterprise registered and established in the Zhongguancun National Independent Innovation Demonstration Zone in 2005. It mainly engages in research on bone conduction sensing technology and the development, production, and sales of bone conduction series products based on bone conduction voice sensor technology. Bone conduction refers to the direct transmission of sound to the inner ear through the vibration of the skull. At present, the company has independent intellectual property rights and multiple bone conduction patents. It is also the only bone conduction product in China that can pass the certification of the National Medical Products Administration and has been selected for the Science and Technology Benefit Plan of the Ministry of Science and Technology. 3. Comprehensive comparison of project technical indicators with similar technologies at home and abroad: Currently, several domestic companies are producing bone conduction products, but there is still room for improvement in terms of technical indicators and performance. Our company is the only bone conduction product registered and certified by the National Medical Products Administration in China; Internationally, countries such as the United States and France have bone conduction headphones. Bone conduction products launched in the United States are developed using component overlap, and the bone conduction headphones developed in the United States are only suitable for people with normal hearing. However, our company's bone conduction products can meet the needs of both normal and congenital deaf mute patients (generally speaking, congenital deaf mute patients are the group with the worst hearing). There are no products or related reports yet, and the conclusion of the search is that there are no similar products.
