TRANSDUCER ASSEMBLY AND ASSOCIATED SIGNAL PROCESSING

Document Type and Number:

WIPO Patent Application WO/2022/007860

Kind Code:

A1

Abstract:

Example embodiments disclosed herein relate to a transducer assembly and associated signal processing. A transducer assembly includes two voice coils in a telescopic arrangement and having unequal sizes, and two suspension systems connected to the two voice coils, respectively. The two voice coils extend in opposites directions from their suspension systems. Dimensions of respective wires of the two voice coils are determined based on respective magnetic flux densities in magnetic gaps for receiving the two voice coils. As a result, a residual vibration caused by the unequal-sized voice coils can be further reduced.
