The scale of digital piano production varies by manufacturer, market demand and region. Some well-known digital piano manufacturers may produce hundreds of thousands to millions of digital pianos every year to meet the needs of the global market. These large manufacturers usually have production bases in multiple countries and establish cooperative relationships with suppliers to ensure production efficiency and product quality. At the same time, there are also some small or professional digital piano manufacturers. Their production scale may be relatively small, but they may focus on producing high-end or customized digital pianos to meet the needs of specific customer groups.
