BODY AND SECURITY SYSTEMS

Delphi Vehicle Sound Generator
Delphi's vehicle sound generator is an environmentally friendly,
single-box sounder that is designed to help vehicle makers
comply with legislation related to the safety challenges of nearsilent hybrid and electric vehicles. Robust enough for underhood
mounting, the high-fidelity sound generator is compact,
lightweight and cost competitive. It features a 32-bit
microprocessor with flash memory, an audio class-D amplifier
and can reproduce melodies that represent vehicle identities.
Though very light, weight of the conventional cone speaker
system can be reduced by 66 percent when a special magnet is
used to activate the system.

Benefits
•

•
•
•
•

Compact, single-box configuration
o Three times lighter than multi-box system
o Simplifies packaging, reduces wiring harness impact,
and eases vehicle mounting
Uses less power than competitive systems, pulling less than 2
amps
Link to vehicle data bus, enabling a warning system that can
offer multiple features
Environmentally friendly: lead-free, waterproof and temperature
resistant
Helps vehicle makers comply with legislation related to the
safety challenges of near-silent hybrid and electric vehicles

With a data connection, the 100 x 100
millimeter unit allows vehicle makers to enable
multiple warning sounds using one sound
generator.
