Smart Speaker

Adhesive solutions for your voice assistant.

Smart speakers began their triumphant progress in 2015. They can now be found in many households worldwide. The intelligent loudspeakers are fitted with a voice assistant and have a wide range of use capabilities. Possible uses go far beyond replaying or streaming music. Smart speakers often serve as control centers for numerous smart home functions.

What are smart speakers?

A smart speaker is an intelligent loudspeaker and far more than a normal loudspeaker. They are fitted with a voice assistant and connected to the Internet. The assistant understands particular voice commands and carries them out. A smart speaker can replay music or other audio files from the local network or from Internet streaming providers and much more. To carry out commands, the loudspeaker records the words spoken in the room via the built-in microphones and waits for a signal word that differs from product to product. It forwards the commands following the signal word for analysis to software on the Internet This uses artificial intelligence (AI) to interpret language and recognize individual voice commands. Smart speakers are not limited just to replaying music. For example, they answer questions about the weather, time or the next appointment. Several of the devices can be integrated into the smart home and enable the user to control all kinds of functions in an intelligent environment.

The smart speaker market boasts tremendous growth rates. In the second quarter of 2019, the market chalked up striking year-on-year growth of 25 percent. Experts expect 200 million devices to have been sold by the end of 2020. As a result, smart speakers are among the fastest growing technologies in the consumer area.

Components of smart speakers and adhesive applications

Smart speakers comprise many individual components. Various loudspeakers with specific properties and frequency spectra, such as sub-woofers, are often integrated. Complex internal structures and special insulation or dampers provide a high-quality audio replay. Vibration of individual components or of the housing must be reliably avoided by corresponding adhesive and attachment technology. Microphones that are usually aligned in several different directions record spoken commands in the surroundings. The motherboard with processor unit and memory are the centerpiece of the smart speaker.

Adhesive solutions are often used for the assembly of these components. Below you will find an overview of the most common applications for smart speakers:

  • Lens mounting
  • Battery mounting
  • FPCs mounting
  • PCBs mounting
  • Antenna mounting
  • Speaker mesh mounting
  • Button fixation
  • Deco/logo mounting
  • Display lamination
  • Shielding and grounding
  • Covering


High bonding strength


Impact resistance


LSE performance










Temperature resistance
