Grammophone® is an exciting advertising material with a unique Call- To- Action that creates a strong connection between a brand and a customer. Grammophone® is a customizable mobile phone holder with a passive loudspeaker as an additional feature.


This product is not only exciting because of its remarkable Call- To- Action, the playful assembly.


Grammophone® is an effective tool when it`s about creating a link between physical Give- Away and digital application (for example promotion for a web radio, website or music act).


Grammophone® is an idea by Hey!blau Labs and is produced in Cologne.



The name Grammophone® stands for a mobile phone holder with the additional function of a passive loudspeaker. Grammophone® does not only look great on your desk and sovereignly supports your next facetime call. On the bedsite table, in the park, at the beach or at the next cooking session your smartphone is very pleased to have a couch with comfort guarantee. During the playful assembly of the set your skilled craftsmanship as well as your patience is put to the test.




With a width of 85 mm almost every smartphone fits into the holder. Through the funnel there is a measurable increase of sound reproduction for all smartphones with a loudspeaker on the bottom (for example all iPhone models).


Grammophone® is an idea by Hey!blau Labs and is produced in Cologne.



If it is especially about motivating someone to take a specific action in the digital space - for example going to a website - Grammophone® is the perfect product. The sustainable craft kit can be distributed as an Onpack, at fairs or events as well as a Call-To-Action relationship gift ect.



With a width of 85 mm almost every smartphone fits into the holder. For all devices with a loudspeaker positioned on the bottom (for example all iPhone models) there is a measurable increase of the sound reproduction.



The production takes place at our location in Cologne. The product is made of cardboard and can therefore be recycled through paper waste. The protective polybags fulfill the DIN ISO 9001 requirements and can also be recycled.



The delivery contains craft kits that can be put together playfully without any additional tools. This way the user spends enough time to develop a connection with the advertised brand.



The inner and outer surfaces can be designed according to your wishes. In order to get a simple realisation primary colours can be chosen and certain surfaces (for example »your logo«) will be printed with your logo. For more unusual variations Grammophone® can be printed with a »360° Design«. There is also room on the packaging for your message. Furthermore a model of your design is shown here.
