Innovative Acoustic Technology and Components

1. Acoustic Technology

Sound is generated when a vibrating object pushes the surrounding air. The shape, material, suspension design, vibration modes, and excitation method of the object all significantly influence its sound characteristics.

  • Traditional Speakers: Rely on the vibration of a lightweight, rigid-body-like conical diaphragm to push air, typically yielding a relatively narrow frequency bandwidth.
  • Flat-Panel Speakers: Produce sound by exciting a flat panel. While this method offers a broader frequency spectrum dependent on material properties, suspension design, and excitation points, it often lacks strong low-frequency response.

Compared to existing acoustic technologies, our proprietary innovation delivers a broader bandwidth and enhanced bass performance. By integrating the vibrational modes and sound-radiation characteristics of both traditional conical diaphragms and flat panels, this technology combines a planar diaphragm with an optimized suspension system. When excited, the planar diaphragm generates optimal mode shapes across different frequencies to push air—resulting in a smoother sound pressure curve, richer low frequencies, and clearer, brighter mid-to-high tones.

2. Acoustic Diaphragm

Featuring high rigidity and light weight, our advanced diaphragm material is ideal for manufacturing flat-panel speakers of various sizes and power ratings. Sample models are listed below:

3. Flat-Panel Speakers

By leveraging this innovative acoustic technology and unique diaphragm material, we can design and manufacture flat-panel, ultra-thin speakers across various power capacities—perfectly suited for integration into all multimedia and 3C (Computer, Communications, and Consumer Electronics) products.
