Solutions for large amplitude and high rated power based on multi-holding in miniature loudspeaker

Solutions for large amplitude and high rated power based on multi-holding in miniature loudspeaker
  • Greatly improve the unbalanced vibration of vocie coil, enable voice coil vibrating with large amplitude, which enhances the sound pressure level at low frequency range. 

  • Integrated with intelligence algorithm, multi-holding solution is able to realize replacing classical large loudspeaker in  some range of sizes, sufficiently enhancing the load power of miniature loudspeaker, and expanding the application area as well.
