The Commercial Engineering (CE) Series drivers from Dayton Audio provides
engineers, designers, and integrators with a line of economical small drivers
that fit the diverse range of applications found in consumer electronics and
audio-enabled electronic projects.
The Dayton Audio CE38M-8 1-1/2” mini speaker features a feather-light and
smooth-sounding Mylar diaphragm and a lightweight injection-molded plastic
frame, making it great for portable electronics and headphones. The high
sensitivity also enables it to be used as a speaker in kiosks, intercoms,
displays, or electronic games, and the 8-ohm impedance works with most small
audio amplifiers or line-level outputs. The round frame can be press-fit or
glued in place.
Note: The Mylar diaphragm is very fragile. To prevent damage, avoid contact
with the diaphragm when handling. This driver should be installed behind a
grille.
