Born2Bond™ for audio equipment
Accuracy, durability, and outstanding performance are key considerations when looking for special adhesives for audio equipment manufacturing. That’s why Born2Bond™ Light Lock adhesives are leading bonding solutions in the audio industry.
The perfect adhesive solution for small manual production runs or large-scale automated production lines-Born2Bond™’s patented Light Lock technology enables rapid bonding of multiple substrates and intricate components.
Precision assembly with Born2Bond™ adhesives ensures optimal sound projection and resonance, while providing the exceptional environmental resistance required by premium audio technology.
Born2Bond™ for the application of in-ear (in-ear) headphones.
In-ear (in-ear) headphones house a complex ecosystem of intricate components. Bonding each element with Born2Bond™ adhesives ensures structural longevity and high-performance acoustic performance.
Assembly of the microphone mesh
In-ear (in-ear) headphones house an intricate microphone protected by a fine mesh material. The microphone enables hands-free calling, voice commands and noise-canceling capabilities. Born2Bond™ high-performance HMPUR, UV-Instant and Instant adhesives support the daily durability of the microphone and its links with exceptional ability to handle vibration and movement.
Electronic encapsulation
In-ear (in-ear) headphones contain sensitive electronic components such as drivers, circuits and connectors. Electronic encapsulation seals and protects electronics and vital components from environmental factors such as dust, moisture, and physical damage. Encapsulating the electronics of in-ear headphones with Born2Bond™ UV-Instant, UV-Epoxy or UV-Acrylate adhesives ensures longevity, reliability and consistent sound quality.
Bonding of magnets
Magnets play a crucial role in the overall design of in-ear headphones, interacting with voice coils to produce sound vibrations. Born2Bond™ high-performance structural adhesives HMPUR, UV-Instant, Instant, and XMA ensure that the magnets are firmly and precisely placed without interfering with the magnetic properties, counteracting unwanted distortions and ensuring that the headset is secured.
Bonding of the diaphragm
The diaphragm, or membrane, is a lightweight, thin and flexible material responsible for acoustic amplification. The diaphragm translates electrical signals into audible sound waves carried throughout the structure. Born2Bond™ instant adhesives are chosen for their ability to form a reliable bond with the thin, delicate diaphragm material.
Bonding of the front tweeter
The tweeter is a small speaker designed to reproduce high-frequency sound waves, which typically cover the upper range of the audible spectrum at the front of the headphone. The tweeter provides crisp, detailed audio and a balanced listening experience. The use of high-performance Born2Bond™ HMPUR adhesives ensures that tweeters resist vibration and maintain stability.
Bonding of active noise-canceling microphones
Noise-canceling microphones capture external ambient noise and generate anti-noise signals to cancel out unwanted sounds. When integrating active noise cancellation (ANC) technology into the structure of an in-ear (in-ear) headset, Born2Bond™ high-performance HMPUR adhesives ensure secure bonding with minimal interference for high-quality microphone performance.
Bonding of the front housing
The front housing, commonly known as the earpiece or headset shell, is the visible outer shell of an in-ear (in-ear) headset that users insert into the ear. The front housing contains and encloses all major components. The use of Born2Bond™ HMPUR high-performance adhesives ensures that all internal components are secured within the enclosure, protecting the electronics from potential damage caused by external elements.
Battery assembly
The rechargeable battery is a key component of in-ear headphones and provides the energy needed to activate wireless functionality, ANC, and other included electronic functions. Using Born2Bond™ Instant, UV-Instant, or Low-Pressure Moulding Hotmelt, the battery cell and its casing are bonded to the casing or headset case, securing it and preventing unnecessary movement.
Born2Bond™ for application to speakers.
Using Born2Bond™ Light Lock adhesives for audio equipment improves vibration and shock resistance, ensuring maximum performance of speaker systems.
Bonding between spiders and voice coils
The spider, also known as a suspension or damper, is a flexible material that connects the voice coil to the speaker frame. The spider keeps the voice coil centered, allowing it to move smoothly and precisely in response to audio signals. Born2Bond™ high-performance HMPUR or Instant Adhesives ensure proper alignment, stability and performance when bonding the spider to the moving coil.
Bonding the spider to the frame
In addition to the voice coil, the spider attaches to the chassis or frame, the structure that holds the various components of the speaker together. The use of high-performance Born2Bond™ HMPUR or instant adhesives provides a strong and secure bond, ensuring that the spider remains connected for the duration of use.
Bonding the cone to the voice coil
The cone, or diaphragm, is the visible part of the speaker that moves in response to audio signals. The diaphragm generates the sound waves, while the voice coil is the wire component that moves inside the magnetic slot, causing the diaphragm to vibrate and produce sound. Bonding between diaphragm and voice coil with Born2Bond™ HMPUR high-performance adhesives, instant adhesives, or XMA structural adhesives forms a strong bond that enables acoustic vibration.
Bonding between cone and dome
The dome is another smaller diaphragm designed to reproduce higher frequencies. The dome diaphragm can be made of fabric, metal or polymer and is glued directly to the center of the dome diaphragm. The use of Born2Bond™ High-Performance HMPUR or instant adhesives ensures that the two diaphragms can move together in response to audio signals, maintaining a powerful bond.
Magnet-to-plate bonding
The plate, or pole piece/back plate, is placed behind the magnet to help shape and focus the magnetic field. The magnetic field interacts with the voice coil, causing it to move and producing sound vibrations. The magnet is firmly attached to the plate using Born2Bond™ High Performance HMPUR, Instant Adhesives or XMA Structural Adhesive to ensure precise alignment and optimal interaction between the magnetic field and the voice coil.
Basket-plate bonding
The basket is the structural framework that supports the vital internal components, while the metal plate helps shape and focus the magnetic field inside the driver. The use of Born2Bond™ instant adhesives ensures excellent structural integrity, optimizing magnetic interaction and efficient sound production.
Surround-cone bonding
The speaker surround, also known as the suspension or surround, is a flexible component that connects the cone to the speaker frame, allowing controlled movement in response to audio signals. The use of Born2Bond™ instant adhesives ensures a strong bond, preventing distortion and improving durability.
Surround-frame bonding
A strong bond between the surround and the frame is critical to ensure durability and longevity. The use of Born2Bond™ Instant Adhesives controls diaphragm movement, prevents distortion, improves overall audio quality, and increases durability by ensuring that the chassis assembly can withstand the stresses of vibration and movement.
Gasket bonding
A gasket is a sealing or cushioning material, usually made of foam, rubber or silicone. Gaskets create an airtight seal between components to prevent air leakage and protect against external elements. Bonding gaskets with Born2Bond™ UV-CIPG Gasketing Adhesive can provide sound insulation by preventing sound leakage, interference and vibration damping, reducing resonance between components.
Logo pasting
Once everything else is secure and glued together, it’s time to add your brand logo. The logo can be of different materials, usually metal, plastic, rubber or fabric. Born2Bond™ UV-Instant or Instant adhesives securely bond the logo, regardless of the chosen substrate.
