Component Benefits

Partnering with ISL for your micro speaker requirements ensures a "Value-Added" solution that maximizes sound pressure level (SPL) in a minimized footprint.

  • High SPL in a Small Package: Optimized to provide clear, audible alerts even in high-ambient-noise environments.
  • Ultra-Lightweight Design: Minimizes total system weight, critical for handheld and wearable devices.
  • Slim and Compact Profiles: Low-profile geometry allows for creative integration in shallow enclosures.
  • Drop-In EOL Replacements: Seamlessly transition away from discontinued components without redesigning your PCB.
  • Custom Mounting Configurations: Available in Surface Mount (SMT), through-hole, or with custom lead wire assemblies.

Component Applications

ISL micro speakers are the driving force behind some of the world's smallest precision devices:

  • Medical Devices: Blood glucose meters, electronic stethoscopes, and infusion pumps.
  • Communications: Cell phones, two-way radios, and drive-through intercom systems.
  • Portable Computing: Laptops, tablets, and handheld GPS units.
  • Laboratory Science: Centrifuges and automated diagnostic equipment.
  • Consumer Tech: Mini Bluetooth speakers, headphones, and electronic toys.
  • Industrial Gear: Handheld packaging equipment and portable testing meters.

Application Specific Micro Speakers

When space is limited, ISL Products Micro Speakers are a compact, quality solution. We work with our customers to design and manufacture Micro Speakers around their intended application, with either a paper or Mylar cone ensuring they have a low profile and slim-line design. Here at ISL Products, we classify any speaker under 25mm as a Mini or Micro Speaker.

ISL’s designs micro speaker solutions with various mounting configurations as well as tailored electrical characteristics. Our immense capabilities were showcased when we designed and manufactured an 18mm Micro Speaker with a 90ohms impedance for a global, Fortune 100 customer. Although they are small, our micro speakers are proven to meet the highest of expectations.

ISL also offers Continuous Source Manufacturing for all types of Micro Speakers. If your incumbent speaker goes end-of-life (EOL), let us know.
