Sony-Ericsson continued its announcements today and released a pair of accessories to make better use of its handsets. The MPS-75 Snap-on Speakers are built specifically for the cellphone maker's W660i Walkman phone and attach to the bottom, providing stereo sound powered entirely by the phone for parties or listening at work. An FM antenna is also hidden away to magnify the reception of the W660i's internal FM radio.

Introduced at the same time is the IPK-100 Camera Phone Kit. Its focus is on improving the quality of photos from Cyber-shot camera phones: a small 3.8-inch tripod steadies the phone for macro shots or self-portraits. A custom case also ships with the kit to keep the phone safe while on a belt or in a bag. Both the kit and the speakers will be available internationally this spring.
