Snap-Fit Type Micro Speaker Unit for Automotive Applications

With the increasing automation of assembly processes, Hosiden has developed and now released a snap-fit type micro speaker unit for automotive applications. The structure of leaf spring contact point and snap-type attachment fitting has enabled incorporation into automated assembly procedures.
With its integrated enclosure this micro speaker unit can maintain its acoustic characteristics regardless of its housing structure within the vehicle. Reduced development cost is also an advantage with this unit, as its consistent acoustic characteristics eliminate the need for redesigns because of differences due to variations in different speaker housings.
