HOMMBRU speakers are similar to the principle of instruments. The vibration sensors (shown in color) set the surface of the respective sound body in vibration. Sound is created. Instruments do not need any black speaker boxes and look good – just like HOMMBRU.

HOMMBRU transfers the principle of structure-borne noise from instruments to an innovative loudspeaker system called distributed mode loudspeaker.
In structure-borne noise, the body itself produces sound by vibration. (You don’t believe that? Tap on your tabletop and hear the sound that comes from structure-borne sound right from your table). The oscillating membrane is made of different solid materials, e.g. solid surface material or wood.

Special electric pulse generators (exciters) ensure the acoustic excitation. The resulting vibration creates sound. We examine very carefully how this movement looks and how the material behaves. The outer shape remains flexible and can be customized according to your wishes and ideas. We guarantee the fulfillment of the highest design and sound standards.

HOMMBRU® Technologie WAVE DESIGN EXCITER menu product principle


HOMMBRU radiates space-filling as a structure-borne sound transducer, works with many materials and is waterproof.


Our technology emits 180 ° sound. Therefore, the same volume is heard everywhere in the room.

design as required

Whether wood, HPL or compact material - HOMMBRU makes many different materials and surfaces sound. And that is invisible from the outside.

Waterresistant and Dust-Free

We only use hard, closed surfaces. Holes, grids or fabric covers for speakers are history.


The differences between HOMMBRU and conventional speakers are many. Basically, a distinction is made between structure-borne sound transducer and airborne sound transducer. In the following figure you can see that HOMMBRU has a large angle of radiation due to the used structure-borne noise of the surface. Airborne transducers, on the other hand, require more depth and radiate the sound in a directed manner.

Influence of the radiation angle - an example

You are in the restaurant for dinner with a friend. You can choose between a table directly at the window or in the middle of the room. Immediately above the table by the window hangs a loudspeaker. You sit down at this table and hardly understand a word from your friend. The music is just too loud. The reason for this is the directional radiation of conventional loudspeakers. The sound waves are sent directly in your direction. In addition, the effect occurs that at the table in the middle of the room hardly any music can be heard. How so? Because the energy of the sound waves has already arrived at your table bundled and no longer penetrates to the middle of the room.

HOMMBRU has a angle of radiation of 180 °. So the sound waves are distributed more evenly and therefore room-filling. Thus, almost the same music volume can be heard both at the window table and in the middle of the room.

How loud can HOMMBRU get?

Concert sound loud.
“Die Prinzen” gave a concert on loudspeakers from HOMMBRU – without any conventional loudspeakers.
