Customization & IP Licensing / Total Sound Solutions




With the ICEpower® MobileSound Solutions, we offer our customers product differentiation by maximizing sound pressure level and sound quality in portable, battery operated devices, while prolonging their battery life, minimizing the physical dimensions and reducing the product cost.

We offer our customers to save time and R&D budget by partnering with ICEpower - the industry specialist in efficient audio power conversion.

The targeted applications of ICEpower MobileSound Solutions are

  • Mobile phones,
  • MP3 players,
  • GPS Navigators,
  • Notebooks,
  • PDA’s,
  • Portable gaming devices.
Currently, we offer two generations of ICEpower MobileSound solutions realized as ASICs. The first-generation solutions (MobileSound1) are based on a class D amplifier with analogue input, available in mono- and stereo speaker versions.

The second generation of solutions (MobileSound2) is based on a fully digital audio power conversion system combining sample rate converters, a DSP core, and class D amplifiers for the headphones and the speaker.

In addition to the physical products, we offer ICEpower® Total Sound Solutions, which includes a wide range of services: from engineering consulting to complete customized design of audio reproduction systems for portable devices.

Depending on in-house competences of a customer, ICEpower can serve as a partner at different levels: from a parts vendor (ASIC’s, transducers, etc.) to an R&D partner delivering Total Sound Solutions, which include components and support in acoustical engineering.

Our MobileSound Vision

The current trend in the portable consumer electronics is to integrate more functionality (MP3 players, Streaming TV, Gaming, Voice Speaker, Video Conversation) into ever more compact portable devices. As a direct consequence, a range of portable products today require high quality audio reproduction systems. Unfortunately, the majority of portable audio systems currently on the market are both inefficient and incapable of meeting the requirements of the applications. We see large opportunities for improving the quality, efficiency and functionality of mobile devices through technology innovation.

Our vision is to take sound reproduction in portable devices to the next level, considering the tight constraints on power consumption and physical dimensions available in such systems. Our vision can be summarized as:

ICEpower Vision for Speaker sound reproduction:
  • High Sound Pressure Level, 100dB SPL/10cm.
  • Good Sound Quality as perceived by the average user, flat frequency response of +/-3dB in the range from 300Hz-20kHz with less than 3% system distortion.
  • Compact size, less than 2 x 1.5CC acoustical system.
ICEpower Vision for Headphone sound reproduction:
  • Intra-concha headphone sound quality on par with the Sennheiser HD600 reference.
  • 110dB SPL in the frequency range 20-20kHz at less than 0.1% system distortion.
Audio Power Conversion Innovation

To realize our vision, we apply a new design paradigm, which is distinctly different from the conventional approaches. Traditionally, each block of the audio power conversion chain is optimized individually. At ICEpower, we focus on optimizing the entire chain, from power management to digital signal processing, to amplifiers, over transducers and acoustical design. Breaking down these boundaries and conventions has enabled ICEpower to gain the leadership in performance, power density and energy efficiency in our markets.
