High-Energy & High-Density Speakers
Entry-Level SLS
Performance Parameters
  • Xmax: 0.4~0.5mm
  • Tmax: 110℃
  • The low-frequency equalizer (EQ) SPL is 3 dB–4 dB higher than the SPS SPL
Technical Features
  • Boosts Xmax through the double-diaphragm structure
  • Devices that require robust low-frequency volume and sound quality such as mid-range and high-end smartphones, laptops, mid-range tablets, and smart glasses
Classic-Level SLS
Performance Parameters
  • Xmax: 0.55~0.8mm
  • Tmax: 120℃
  • The low-frequency EQ SPL is 3 dB–4 dB higher than the entry-level SLS SPL
Technical Features
  • Boosts Xmax through the double-diaphragm structure
  • Increases magnetic energy density thanks to higher magnetic steel content, coil grids, and square coil wires
  • Uses a rubber membrane to boost low-frequency sound quality
  • Reduces size by 40% or manufactures standardized products
  • Devices that require excellent performance, sound quality, and audio experience such as high-end smartphones, high-end tablets, and smart glasses
Master-Level SLS
Performance Parameters
  • Xmax: 0.65mm
  • Tmax: 110℃
  • A 50% size reduction yields the same performance as the Classic SLS, or a 50% performance increase for the same size
Technical Features
  • Separate vibration and magnetic circuit systems enhance performance
  • The new magnetic circuit structure and ultra-narrow folding ring diaphragm drive up performance
  • All-metal 3D bass encapsulation increases the equivalent rear cavity space
  • Devices that require outstanding performance, sound quality, audio experience, and spatial stackup such as flagship smartphones, foldable smartphones, and AR/VR devices
Innovative Coaxial Technology
Back-to-back Laptop Speaker
Performance Parameters
  • Coaxial derivative technology is used to achieve low- and high-frequency extension of the speaker, while significantly reducing the impact of speaker vibration on the device
  • The speaker covers a wide sound range from 200Hz to 14kHz
Technical Features
  • The special bi-directional diaphragm design makes the speaker slimmer and lighter
  • The super linear structure of FPCs minimizes rolling
  • Devices that require high sound volume, such as laptops
Back-to-back Phone Speaker
Performance Parameters
  • Xmax:0.3mm
  • Tmax:110℃
  • AAC's privacy-enhanced calling solution employs back-to-back speaker technology to suppress sound leakage in the low-frequency range. Furthermore, the solution uses algorithms to boost isolation in the mid-frequency range by an average of 10dB, thereby enhancing call privacy
Technical Features
  • The special bi-directional diaphragm design makes the speaker slimmer and lighter
  • The super linear structure of FPCs minimizes rolling
  • Smartphones that require exceptional call privacy
Ultra-Slim Series
Ultra-Slim Series
  • We deliver a whole series of speakers for TVs, including full-range speakers, tweeters, and woofers. Our featured product is an ultra-slim speaker series that is thinner and boosts performance by 2 dB over rival products.
TWS Earphone Drivers
  • We offer a full range of earphone drivers for TWS earphones. Our featured high-excursion, high-sensitivity earphone drivers provide customers with better low-frequency performance while cutting power consumption. The ultra-slim moving-coil earphone driver comes in at just 1.7 mm.
  • High-excursion moving-coil earphone drivers
  • High sensitivity, low power consumption, and increased lifespan
AR&VR Speakers
  • We provide speaker design and manufacturing services for AR&VR.
  • AAC featured super-linear high-excursion speakers:ultra-slim, quality sound across the gamut of frequencies, low power consumption
Smartwatch Speakers
We provide speaker design and manufacturing services for smartwatches.
  • Water resistant (0.5 ATM)
  • Ultra-thin
  • High volume
All-Metal Encapsulation (AME) Technology
Better performance:
improves low-frequency performance, boosts loudness, and increases SPL by over 2.5 dB
cuts cavity space by over 40% compared with classic speaker boxes, making stackup easier
applies ultra-slim all-metal encapsulation to reduce weight by 40%–50% compared with the conventional speaker boxes
Enhanced heat dissipation performance:
cuts the temperature of speaker voice coil by more than 10°C
