Complementary asymmetric transducer configuration for lower distortion and extended range

摘要

An improved loudspeaker system includes an asymmetrical array of dissimilar drivers, namely a first driver and a second complementary driver configured in an array and driven in parallel so that the measured on-axis frequency response and the output power (SPL) is improved as compared to a symmetrical array (with similar or matched midrange or mid-bass drivers), while retaining a flat tonal balance. This speaker system and method for voicing was discovered to provide lower distortion, improved frequency response and greater clarity as compared to the prior art or traditional (e.g., MTM) loudspeaker configurations.

主权项

1. An improved loudspeaker system, comprising:
at least a first driver having a first set of acoustic parameters and a second complementary driver having a second set of acoustic parameters which are different than, but complementary to the acoustic parameters of the first driver's parameters; said first driver comprising a first diaphragm and a first suspension system having a first selected CMS compliance and a first selected KMS stiffness when affixed to said diaphragm in a first forward orientation; said second driver comprising a second diaphragm and a second suspension system having a second selected CMS compliance and a second selected KMS stiffness when affixed to said diaphragm in a second reverse orientation; wherein said first driver's first selected CMS compliance and first selected KMS stiffness during an inward excursion are substantiall equal to said second driver's second selected CMS compliance and second selected KMS stiffness during an outward excursion, thereby providing acoustic parameters for said first driver which are complimentary to said second driver; and wherein the first driver and the second driver are configured upon a surface or within an enclosure to combine and act as one driver when driven with the same drive signal, thereby providing first and second complementary asymmetrical drivers.
