Earth Magnets Improve Speaker Output

A new micro-speaker utilizes rare earth magnets for improved ruggedness and output performance. The TRS speaker is designed in either round or oval configurations with diameters ranging from 13 mm to 66 mm with speaker impedance at 8Ω within a frequency range of 150 Hz to 20 KHz depending on size and shape. Power outputs run from .005W to 5.0W. The TSR speaker is available as PCB or wire lead mounting with paper or Mylar diaphragms as no charge options. Samples may be requested.
