Abstract

The present invention relates to a mobile handset comprising a handset housing comprising a front and a back cover, display means being visible from the front cover side of the handset housing, the display means being adapted to provide visual information to a user of the mobile handset. The mobile handset further comprises a plurality of loudspeakers being adapted to generate audio signals, wherein each of the plurality of loudspeakers comprises a magnetic circuit comprising a magnet, the magnetic circuit having at least one gap defined between two opposed and substantially parallel surfaces of the magnetic circuit. The magnet of the magnetic circuit causes a magnetic field to exist across the at least one gap. The magnetic circuit is so arranged that it defines magnetic return paths completely encircling the gap.

Description

technical field [0001] The invention relates to a mobile handset with a multi-speaker system. In particular, the invention relates to mobile handsets with LCOS displays suitable for near-to-the eye applications, and multiple speaker systems. Background technique [0002] Currently, mobile phones, such as cell phones, PDAs (Personal Digital Assistants), etc., only have a single speaker for providing a single audio signal. Stereo sound reproduction has not become an important issue because, for example, the loudspeakers of mobile phones are already positioned very close to the listener's ears. [0003] With the development of the telecommunication industry now, mobile handsets are required to provide high-quality audio signals. Recent near-eye displays for mobile devices provide sufficient solutions for high-quality color pictures, enabling new applications such as watching movies using mobile phones from a distance of 5-10 cm from the user's eyes - so-called near-eye applic...
