What is MAR.Voip

MAR.voip is a patented technology based on piezoelectric actuators that allow existent structures (walls, furniture, glasses, accessory of furniture…) to switch into emitters and structural receivers.

Therefore, this technology is able to create speakerphone calls while the surrounding structure acts as an actuator, reproducing the speaker’s voice and the user’s one at the same time. In this way the conversation suits the environment and permits the user to easily move into the setting.

The system can be linked with any device equipped with Bluetooth or analogic connection (PC, mobile phone, tablet, etc…) and can be used for traditional phone calls, Skype calls or through other communication apps.

Why MAR.Voip

DATA DENSITY. The spatial distribution of the patches guarantees an high “sound density” that allows structures to capture the human voice through piezoelectric elements. Thus, there isn’t a single point microphone for sound/voice acquisition but a whole plane surface: this makes the sound capture level of MAR.Voip equivalent to an array microphone one’s.

FLEXIBILITY. The system can be installed in the most part of the existing structures such as domestic environment or office.

DISCRETE. The piezoelectric actuators’ sizes are comparable to a common stamp (20X20X1mm). Therefore, they’re well hidden.

FUNCTIONALITY. Mar.Voip can be used for telephone conversations on speakerphone, for audio message record, videoconferences etc.

SMART TECHNOLOGY.  The system can interface any devices equipped with Bluetooth or analogical output

How to  install MAR.Voip

COLL voip 1 ing



The installation of MAR.Voip technology requires the following elements: power feeder at 240V A/C, 60W, amplifier with integrated Blue-tooth, bipolar cable with external shielding for low frequency, piezoelectric ending (sizes: 20X20X1mm).

The microphone’s capability is guaranteed by the phenomenon itself, as all the acquired sound waves impact on the structures where the patches are applied. The generated vibration is then transformed into an analogical signal by the endings. Thus, the signal is sent to the amplifier and then to the microphone channel of the device that it’s being used for the call.


Materials MAR.Voip

By using piezoelectric endings as actuators MAR.Sound allows passive structural surfaces (for example wood, cement, metal, marble, glass, etc) to transform themselves into active ones, and then control them electrically as sound emitter or receiver.

The possible installations of piezoelectric endings are quite a lot: grids, doors, tables, fixtures and any other plain surface can be equipped with MAR.Sound technology.


Spec. MAR.Voip

POWER SUPPLY FEEDER 240V.24V Minimal power: 60W, input 240V A/C, output 24V D/C stabilized.
AMPLIFIER DEDICATED Integrated Blue-tooth, adjustable gain that can drive up to 30 endings, size: 150X100X30mm. Note: in case that it is necessary to install more than 30 endings, it’s necessary to arrange more than one amplifier.
PIEZOELECTRIC ENDINGS Power absorption in speaker  mode: 1W; sizes 20X20X1mm.
AUDIO SIGNAL CABLE FOR RECEPTION Bipolar, external shielding for low frequency is mandatory (e.g. FROHH2R 450/750V).
