ACOUSTIC TRANSDUCER COMPRISING A PLURALITY OF COAXIALLY ARRANGED DIAPHRAGMS

摘要

An acoustic transducer includes a housing, a plurality of diaphragms suspended from the housing and separated into one or more groups, and one or more motors combined with the housing that operate in response to an electrical signal. The diaphragms of each group are driven by a respective motor to which all the diaphragms in the group are coupled and at least one motor has an indirect coupling with no direct mechanical connection to the diaphragms driven thereby. One or more electromagnetic motors that drive one or more sets of multiple diaphragms to provide acoustically efficient loudspeaker systems having dimensions that allow use in applications that would be difficult or impossible with traditional transducers.

1. An acoustic transducer comprising:
a housing; a plurality of diaphragms suspended from the housing and separated into one or more groups; and one or more motors combined with the housing and operating in response to an electrical signal; wherein the diaphragms of each group are driven by a respective motor to which all the diaphragms in the group are coupled and at least one motor has an indirect coupling with no direct mechanical connection to the diaphragms that it drives.
