2. Brief Description of the Prior Art
Video and audio players are getting smaller in size, and quality of output sound and images higher with progress of electronic technology, satisfying the consumers' need.
Home VCD and DCD players, portable CD players, portable tape players, iPOD, radios are among the currently existing video and audio players. Even desktop and laptop computers can be used to play out sound and images. Sound exists in wav format in the early days, which is gradually replaced by mp3 format because mp3 has a greater compressibility and takes up less storage space. And, portable multimedia players (PMP) are getting more common with ever increasing data capacity and size reduction of storage devices.
Portable multimedia players are easy to carry because they are small-sized and light-weighted. However, it is difficult for the elderly to clearly see the characters and images on the relatively small display screen of a portable multimedia player. Further, because the users have to wear earpieces in using the portable multimedia players, they are prone to hearing damage even though the volume of the sound output from the portable multimedia players is low.
