Operating principle

Kendrion – as an expert in AVAS-compliant exterior sound solutions – develops active and passive loudspeakers for hybrid and electric vehicles.

The active loudspeaker system – our new One-Box solution – includes a Kendrion loudspeaker and a built-in control unit. This application represents a new software concept for the external sound of vehicles.

Our One-Box solution reproduces a warm and brilliant sound and fulfils the global sound level requirements. Thanks to a master-slave functionality, it can be combined with a co-ordinated additional actuator offering additional safety potential when reversing.

The exterior sound system of Kendrion Automotive gives you the opportunity to create a credible and suitable sound for your electric and hybrid vehicles. Using our system, you can parameterise your brand specific sound to create an addional recognition value and more safety in traffic.

The Kendrion Sound System fulfils all requirements of the AVAS legislation.

Electronic control unit

The electronic control unit from Kendrion has proved its worth in automotive series production applications for many years and is offering exceptional reliability.

Temperature stability and a robust and protected design to prevent dust and water ingress are additional key features. Basically, our control units are EMC-conform to eliminate an undisirable interaction with other electronic units.

Plugs, installation spaces and mounting options will be matched in cooperation with the customer. The control unit is available with one or two channels so that the soundpackage is expandable e.g. with an in-cabin sound, so that also the passengers can experience the new sound.

The electronic control units can also be used for other application areas. Get more information Electronic Control Units.

Sound Design Software

The Sound Design software is besides of the hardware an important part of the Kendrion sound system.

The Kendrion Automotive Software for parameterisation of the motor sounds allows the creation of a brand-specific vehicle sound.

We offer two options:

  • You can rely on a personally tailored sound profile.
  • We provide the software, which allows you to create an own sound on the graphical user interface.

With the interface to the CAN-Bus all vehicle datas, which are needed for a specific sound generation, will be read. These include the engine speed, the speed and load as well as the current position of the pedal. In order to cover a wide frequency range, there is a sampling rate of up to 22.5 kHz.
