1. Is there a patent certificate or patent authorization?
The technology patent and appearance patent of Chinese learning machine belong to Shenzhen Er Shen Science and Technology Co., Ltd. These patent certificates can be found in official website, Er Shen. In order to further confirm the authenticity, they checked and verified it on the official website of the State Patent Office, and the result was true, indicating that the Chinese learning machine produced by Er Shen Science and Technology was genuine.
So have other China learning machines been authorized by Er Shen Science and Technology to produce or sell? I contacted the relevant person in charge of Er Shen Science and Technology. It is understood that Er Shen Science and Technology has not authorized any China machine manufacturers, that is, other China machine manufacturers have not obtained production licenses. The person in charge of Er Shen Science and Technology also said that the quality of these cottage Chinese learning machines in the market has seriously affected the user's use effect, which is very harmful to children's hearing. In order to provide children with a good educational environment and high-quality learning machines, Er Shen Science and Technology said that it would join forces with the State Administration for Industry and Commerce, the Intellectual Property Office and the Copyright Administration to crack down on counterfeit products and bring a lawsuit to the court if necessary.
2. Is the content genuine?
Besides sound quality, the content of Chinese learning machine is more important. The choice of content and the quality of reading aloud determine the quality of a Chinese learning machine.
The contents of all Chinese learning machines are basically the same, taking the first-generation product catalogue of Er Shen Genius Chinese Learning Machine as the core, and then adjusting some orders or adding some other contents. But the pronunciation of the content is different, which is very important. If the pronunciation or intonation is not standard, it will have a serious negative impact on children's voice and mood.
