Hoin Electronics Pte. Ltd. is a Taiwanese owned company, located in Shiwan Town, Boluo County, Huizhou City, Guangdong Province. Hoin specializes in the manufacture of speaker
diaphragms. We have been in the speaker market for over 30 years, and we have received good reputations from our customers.

In order to satisfy international customer's demands for waterproof acoustic products, a new brand name of KAIQIN has been established.

KAIQIN is a brand name formed under Hoin. Our business includes the development and production of waterproof acoustic products. The existing product line consists of waterproof
earphones, waterproof MP3 players, waterproof speakers and a series of underwater use acoustic products. There might be a misleading concern of Tenlex being in contention with
existing speaker assembling factories. As to this, we would like to clarify the fact that the speaker units used in the waterproof products are all produced by our customers.
Tenlex only provides the diaphragms.

Our speaker units are further processed in Tenlex to achieve waterproofing capability. We hope to further expand the markets for our customers through the breakthrough in
waterproof products, and under the protection of international patents.
