Address: Heping Industrial Park ,DongQing Town, Changzhou, Jiangsu, China, 213000
Tel: 86-0519-83822009
The FHD Company has been producing cutting edge acoustic components for 18 years now. We have focused our research and development efforts on our main line of products which are: Electromagnetic and Piezo Transducers/Buzzers Mylar Speakers and Reciver Loud Speakers and Alarm parts We employ over 500 people in our factory and 20 full time engineers in our R&D division. None of them are new comers to the field, and some of them have 10 years or more of experience in acoustic technology. We already have some 5,000 square meters at our facility devoted to production, and so our monthly production capacity is upwards of 2,0000,000 finished pieces. Most of what we produced in 2012 was exported to the high quality markets in Europe and the United States. One of the reasons we have been so successful competing in this field is that all of our test and production equipment is the finest that money can buy from Japan, the United States, and Europe. Our products are designed for most common audio applications such as telephones pagers modems multi-media computer accessories radio/cassette recorders voice-recording toys alarm systems Much of our production is based on custom orders. We build to our customer鈥檚 exact specifications. Our ability to meet our customer鈥檚 needs in both off the shelf production as well as contract production is second to none. We welcome your inquiries. We will do everything in our power to meet or exceed your expectations.
