Voice coil degumming, heat resistance, low efficiency? What voice coil glue to use

As the "heart" of electroacoustic devices such as speakers, headphones, and vibration motors, the bonding process of voice coils is directly related to the stability and service life of product sound quality. High temperature resistance, vibration resistance, insulation protection, fast curing...... In the face of multiple challenges, how to choose the right glue?

BoNT recommends

Lock glue Anti-Kraft paper warping special voice coil glue

■Strong bonding, firmly connect the wire and the outer wall of the voice coil

■Triple protection: anti-oxidation + anti-conduction + insulation positioning to extend the product life

■ Fast solidification at room temperature, film formation and heat resistance of 185°C, both efficiency and performance

■Applicable scenarios: micro speakers, TWS earphones, precision motor coil fixation

SV rubber horn voice coil wire bonded to the skeleton high-temperature resistant glue
