SPEAKER-1318-2.5-SC-GRAND
The 13x18x2.5 mm Grand speaker provides
maximum space efficiency and audio
performance in small, slim consumer devices,
such as mobile handsets or smartphones. The
extremely flat speaker has the same space
consumption compared to conventional
11x15x3.5 mm speakers but provides an
improved acoustic performance resulting in a
lower resonance frequency (750Hz) and higher
power handling capacity (600mW).
An advanced triple magnet concept provides
optimized acoustic sensitivity.
Features:

•
Extremely slim design with only 2.5mm
height
Low resonance frequency (750Hz)
600 mW power handling capacity
Triple magnet technology for improved
sensitivity
Very robust spring connectors
100% in-line measurement of all
specified electrical and acoustical
parameters
