DELO: Adhesives for high-fidelity acoustics with strict technical requirements

Whether in smart speakers, smartphones, or headphones, loudspeakers are built into many electronic devices. These electromagnetic systems consist of a variety of parts that are bonded together.

The sound quality of a loudspeaker is determined not only by its individual components, but also by the quality of the adhesives used to join these components. DELO has developed special products that improve acoustics and meet the strict technical requirements for power density, temperature resistance, and strength. The speaker adhesives are also designed for fast and fully automated production.

Suitable adhesives for loudspeaker manufacturing

DELO PHOTOBOND adhesives are suitable for bonding a wide range of plastic components. Due to the fact that they cure within seconds, they allow particularly fast processes. The fluorescence of the adhesives enables reliable application control in automated processes. DELO DUALBOND adhesives combine the advantages of light curing with a second curing mechanism by moisture or heat. These products enable fast processes in combination with safe curing in shadow zones. For structural bonding, the products of the DELO MONOPOX series, which cure by heat, are suitable.
