A 28-year manufacturing group behind one speaker brand — tooling, plastics, electronics and acoustics under one roof, serving OEM and ODM customers worldwide.
ZEHSM is the speaker and audio-component brand of Zhejiang Zhongyihong (ZEH) Electronic Technology Co., Ltd, founded in Jiashan, Zhejiang in 1998. What began as a precision metal-mould factory is today a group that covers tooling, plastics, electronics and acoustics in its own factories.
Since 2008 the group has focused on loudspeakers — drivers, micro speakers, tweeters, full-range units and complete modules. Products are engineered in Shenzhen, tooled and produced in Jiashan, and shipped to OEM and ODM customers across Europe, the Americas and Asia.
Founded in Jiashan, Zhejiang as a precision metal mould factory with a 5,000 m² workshop.
Speaker business unit and plastic injection moulding department established.
Shenzhen branch opened and the ZEH brand created for speaker R&D and design.
PCBA department formed to integrate speakers, microphones and boards with tuning and test.

Precision tooling and metal parts machined in our Jiashan factory — the business we started with in 1998.
Automated assembly for amplifier and control boards that pair with our speakers and microphones.
