Bms compression driver patent

Recently BMS licensed the patent to a major US speaker company that has been manufacturing drivers for decades in an effort to save money on shipping and import duty. Try as they might, this company could not replicate the BMS diaphragm. Wave guide compression driver BMS , 8 ohm, 4 inch. Unique Planar Wave Design (patent pending)Neodymium Magnet AssemblyPerfect acoustical coupling of individual units to create virtually continuous line source dB sensitivity 1 W / 1 m1 kHz CrossoverExtended high frequency response up to 20 kHz.

An annular diaphragm compression driver for electro-acoustic conversion has an annular diaphragm, which bears a moving coil, and a compression driver housing with a closed housing base. Opposite the housing base is a sound wave routing element having a sound discharge channel. The compression driver also has an annular magnet system unit, which has an annular magnet gap (M) and a Cited by: 5.

The patented design of the BMS ND is a result of extensive dedicated research and development providing dramatic improvement in dynamic response, clarity and transparency. The larger annular midrange diaphragm covers the frequency range between 4Hz with a smooth, linear response. The BMS ND is a unique transducer that uses a neodymium coaxial compression driver to drive a planar waveguide intended for use in line arrays. BMS Speakers patented the two-way compression driver technology in This month’s Test Bench subject, the ” ND features a Hz to kHz bandwidth (6 to 22 kHz for the tweeter and Hz to kHz for the midrange). The BMS ND planar wave driver radiates a coherent planar wave front form a rectangular piston without internal diffraction for superior dispersion control and high fidelity sound. This distinctive new transducer was engineered to work with 4-inch (4” x 1”) rectangular throat waveguides providing extremely high sensitivity.
