Research and development department is ongoing research projects:

一. the development of electro acoustic device 

1, vibration speaker: the development of a sound in the air, directly promote the human auditory nerve devices, to provide more comfortable use of feelings, for special occasions communication. 

2. iron type loudspeaker: development of a size is only about 5 mm speaker, and has high sensitivity and satisfactory response curve, used in headphones, phone, expect it can replace now moving coil type loudspeaker and become the next generation of electroacoustic devices mainstream

二.Audio signal processing technology

 1, based on the DSP hardware platform, based on the multi sample rate signal processing, sub band decomposition technology, audio signal dynamic range compression algorithm, speech enhancement algorithm. 

 2, based on the DSP hardware platform based on the dimension of the filter technology, echo cancellation and active noise reduction algorithm. 

三. electronic technology based on 2.4G wireless transmission hardware, the development of wireless control audio transmission technology, realize the small size of wireless, anti strong electromagnetic interference of hardware and software design and so on. 

四. Mechanical design technology for product reliability design under extreme conditions, to achieve the products in large temperature range and reliable work (- 40 DEG C ~ 80 DEG C). High impact resistance, waterproof, dustproof, explosion-proof, resistant to harsh climatic conditions and achieve high reliability of the product structure. 

五. Production design technology upgrade is mainly based on PLC, the current production equipment to automate transformation.
