The voice coil motor for the flexible vibration disk has been the main product of Tongmao Electronics Co. , Ltd. in Kunshan for nearly two years. 

      There are four types of voice coil motors for TMEC0003-002-300-25, TMEC0003-002-300-37, TMEC0020-003-303-51 and TMEC0020-003-303-55. 

      The difference between TMEC0003-002-300-25 and TMEC0003-002-300-37 is that the outer aluminum spring coupling has an outer diameter of 25 mm, and the outer diameter of TMEC0003-002-300-37 aluminum spring coupling has an outer diameter of 37 mm, the outer diameter of the TMEC0020-003-303-51 aluminum spring coupling is 51 mm, and the outer diameter of the TMEC0020-003-303-55 aluminum spring coupling is 55 mm. The aluminum spring couplings used in the motor of the disc voice coil supplied by Tongmao flexible vibration are manufactured by Tongmao machining center. The couplings are made of high-strength aluminum alloy and are spiral cut with good flexibility, its role is to be used to move the stator and rotor firmly connected, and transfer the movement of mechanical parts. The peak thrust of TMEC0003-002-300 is 3N, the stroke is 2mm, the volume is smaller, the peak thrust of TMEC0020-003-303 is 20N, the stroke is 3mm, the volume is bigger. 

    In addition, in addition to providing standard models of voice coil motors for flexible vibration discs, Tongmao can also be customized according to customer needs. Tongmao is a high-tech enterprise with more than 10 years’experience and independent research and development capability, you’re welcome to stay tuned.
